Interventions to improve adherence to antiretroviral therapy in children with HIV infection

The Effectiveness of Patient Training in Inflammatory Bowel Disease Knowledge via Instagram: Randomized Controlled Trial

Background

Patients’ knowledge was found to be a key contributor to the success of therapy. Many efforts have been made to educate patients in their disease. However, research found that many patients still lack knowledge regarding their disease. Integrating patient education into social media platforms can bring materials closer to recipients.

Objective

The aim of this study is to test the effectiveness of patient education via Instagram.

Methods

A randomized controlled trial was conducted to test the effectiveness of patient education via Instagram among patients with inflammatory bowel disease. Participants were recruited online from the open Instagram page of a patient organization. The intervention group was educated via Instagram for 5 weeks by the research team; the control group did not receive any educational intervention. The knowledge about their disease was measured pre- and postintervention using the Inflammatory Bowel Disease Knowledge questionnaire. Data were analyzed by comparing mean knowledge scores and by regression analysis. The trial was purely web based.

Results

In total, 49 participants filled out both questionnaires. The intervention group included 25 participants, and the control group included 24 participants. The preintervention knowledge level of the intervention group was reflected as a score of 18.67 out of 24 points; this improved by 3 points to 21.67 postintervention. The postintervention difference between the control and intervention groups was 3.59 points and was statistically significant (t_32.88=–4.56, 95% CI 1.98-5.19; P<.001). Results of the regression analysis, accounting for preintervention knowledge and group heterogeneity, indicated an increase of 3.33 points that was explained by the intervention (P<.001).

Conclusions

Patient education via Instagram is an effective way to increase disease-related knowledge. Future studies are needed to assess the effects in other conditions and to compare different means of patient education.

Facilitators and barriers to antiretroviral therapy adherence among HIV-positive adolescents living in Tanzania

BACKGROUND

Adolescents living with HIV face substandard outcomes along the continuum of care, including higher rates of poor adherence and virologic failure. Support groups have been identified as a method to improve adherence, but there is insufficient evidence regarding their effectiveness. This study seeks to examine the protective influences for and barriers to antiretroviral therapy (ART) adherence in HIV-positive adolescents living in Tanzania.

METHODS

This is a qualitative study conducted in Tanzania from January to March 2018. The sample of adolescents aged 10-19 (n = 33) was purposefully selected based on age, gender, and support group attendance to capture a broad range of experiences. Participants completed an in-depth interview, covering topics such as retention in HIV services, support group experiences, and joys and challenges of adolescent life. Interviews were coded and themes related to ART adherence were identified and summarized.

RESULTS

Support groups helped promote adherence by improving adolescents' knowledge and confidence. Participants associated joining support groups with an improvement in health. Almost every participant described the significant positive influence a treatment supporter had on adherence. Adolescents' daily schedules and emotional state served as a barrier to adherence. Furthermore, adherence was negatively impacted by participants' fear of accidental disclosure.

CONCLUSION

Logistical and psychosocial factors can hinder adherence. Interventions that provide both education and psychosocial support, such as peer support groups, have the potential to improve health outcomes for this population, but may not address more persistent barriers to adherence rooted in lack of treatment support from family members or friends who have not been disclosed to, or lack of transportation funds/food security.

Improving viral load suppression among men and children active in care through community-designed and led solutions: Protocol for retrospective closed cohort study in Eastern Uganda (Preprint)

Background

In collaboration with facilities, communities, district local government, and the United States Agency for International Development (USAID) implementing partners, the iDARE methodology was implemented at the community level to address root causes of low HIV antiretroviral therapy adherence among men and children actively enrolled in care, resulting in low viral load suppression (VLS) in two districts in the eastern region of Uganda. The methodology encourages the use of cocreated sustainable solutions addressing gender, youth, and social inclusion issues to reduce barriers to care and reach the 95-95-95 Joint United Nations Programme on HIV/AIDS target for HIV epidemic control. We aim to measure the impact of iDARE on VLS for men and children active in care and investigate the practical scale up of the solutions designed using the iDARE methodology.

Objective

The primary objective of this study will be to measure the implementation impact of the iDARE methodology at the facility and community levels on VLS for people living with HIV. The secondary objective is to investigate the practical scale up of the iDARE methodology using evidence-based gender, youth, and social inclusion social behavior change packages to rapidly meet the Ugandan Ministry of Health targets for VLS.

Methods

A retrospective cohort study design will be used to analyze program data that aims to increase the rates of VLS in men and children who are classified as active in care using community engagement and quality improvement techniques. We will examine 3 pilot health centers’ data from a USAID-funded program aimed at social behavior change to increase health-seeking behavior in Uganda. Based on the iDARE process and results, change packages were developed to highlight lessons learned and best practices in order to share with subsequent implementation sites.

Results

The USAID-funded Social and Behavior Change Activity began implementation of iDARE in September 2020, with baseline data collected in August 2020.

Conclusions

Data on viral load suppression was collected from facilities on a monthly basis to record progress toward the 95-95-95 goal. The expected primary outcome is an increase in actively enrolled men and children reaching VLS in order to meet the Ugandan Ministry of Health target of 95% VLS among those active in care.

Importance of support groups to the health and well-being of vulnerable children and young people living with HIV: a case study of the Kids Clubs program in Haiti

BACKGROUND

Although access to antiretroviral therapy (ART) among children and young people living with HIV has increased in recent years, adherence to medication and viral suppression remain challenges. Evidence of benefits of support groups is growing and reflects a range of models and approaches. Since 2014, hospital-linked psychosocial support groups for children and young people living with HIV, known as Kids Clubs, have been established throughout Haiti. The program provides safe spaces for them to meet with peers, supports medication adherence, delivers health and life skills education, and facilitates linkages with clinic visits and social services. This study describes program enrollment and participant engagement, ART adherence and viral suppression among participants, and other outcomes attributed to the program by participants, caregivers, and program implementers.

METHODS

Our mixed methods study included quantitative analysis of program monitoring data on rollout and attendance, and medication adherence and viral load results extracted from medical records. We collected qualitative data from club members, caregivers, and implementers about their experiences with the clubs and the impact of participation.

RESULTS

From January 2014-December 2018, 1330 individuals aged 8-29 were enrolled in the program; over three-quarters participated for at least 12 months. In 2018, 1038 members attended at least one club meeting; more than half missed three or fewer monthly meetings. Three-quarters of ever-enrolled members reported consistent medication use at their most recent clinic visit; 64.2% (600/935) of those with a recent viral load test were virally suppressed. Level of club attendance was positively associated with ART adherence (p < 0.01) and viral suppression (p < 0.05). Club members, caregivers, and implementers noted the value of the clubs to participants' retention in care and medication adherence, health knowledge, and capacity to deal with peer pressure, stigma, shyness, and depression.

CONCLUSIONS

The Kids Club program has been successful in scaling HIV support services to highly vulnerable children and young people through peer-based groups, and program participation has led to a range of benefits. Efforts to innovate, evaluate, and scale support strategies for vulnerable young populations must be accelerated in order to ensure that they survive, thrive, and reach their full potential.

Time to treatment disruption in children with HIV-1 randomized to initial antiretroviral therapy with protease inhibitors versus non-nucleoside reverse transcriptase inhibitors

BACKGROUND

Choice of initial antiretroviral therapy regimen may help children with HIV maintain optimal, continuous therapy. We assessed treatment-naïve children for differences in time to treatment disruption across randomly-assigned protease inhibitor versus non-nucleoside reverse transcriptase inhibitor-based initial antiretroviral therapy.

METHODS

We performed a secondary analysis of a multicenter phase 2/3, randomized, open-label trial in Europe, North and South America from 2002 to 2009. Children aged 31 days to <18 years, who were living with HIV-1 and treatment-naive, were randomized to antiretroviral therapy with two nucleoside reverse transcriptase inhibitors plus a protease inhibitor or non-nucleoside reverse transcriptase inhibitor. Time to first documented treatment disruption to any component of antiretroviral therapy, derived from treatment records and adherence questionnaires, was analyzed using Kaplan-Meier estimators and Cox proportional hazards models.

RESULTS

The modified intention-to-treat analysis included 263 participants. Seventy-two percent (n = 190) of participants experienced at least one treatment disruption during study. At 4 years, treatment disruption probabilities were 70% (protease inhibitor) vs. 63% (non-nucleoside reverse transcriptase inhibitor). The unadjusted hazard ratio (HR) for treatment disruptions comparing protease inhibitor vs. non-nucleoside reverse transcriptase inhibitor-based regimens was 1.19, 95% confidence interval [CI] 0.88-1.61 (adjusted HR 1.24, 95% CI 0.91-1.68). By study end, treatment disruption probabilities converged (protease inhibitor 81%, non-nucleoside reverse transcriptase inhibitor 84%) with unadjusted HR 1.11, 95% CI 0.84-1.48 (adjusted HR 1.13, 95% CI 0.84-1.50). Reported reasons for treatment disruptions suggested that participants on protease inhibitors experienced greater tolerability problems.

CONCLUSIONS

Children had similar time to treatment disruption for initial protease inhibitor and non-nucleoside reverse transcriptase inhibitor-based antiretroviral therapy, despite greater reported tolerability problems with protease inhibitor regimens. Initial pediatric antiretroviral therapy with either a protease inhibitor or non-nucleoside reverse transcriptase inhibitor may be acceptable for maintaining optimal, continuous therapy.

"We give them threatening advice…": expectations of adherence to antiretroviral therapy and their consequences among adolescents living with HIV in rural Malawi

INTRODUCTION

Many adolescents living with HIV in sub-Saharan Africa struggle to achieve optimal adherence to antiretroviral therapy (ART), but few studies have investigated how their treatment-taking decisions are influenced by their social interactions with providers, caregivers and community leaders. This study aims to explore the narratives that define expectations of adherence to ART among adolescents living with HIV in a rural Malawian setting.

METHODS

Overall, 45 in-depth interviews were conducted in 2016 with adolescents living with HIV, caregivers, health workers and community leaders, and four group sessions using participatory tools were undertaken with adolescents. Interviews and group sessions were audio-recorded, transcribed and translated into English. Data were coded inductively and analysed thematically.

RESULTS

Adolescents were given strict behavioural codes around optimal treatment adherence, which were often enforced through encouragement, persuasian and threats. In HIV clinics, some staff supported adolescents with broader concerns relating to living with HIV, but other measures to address sub-optimal adherence in HIV clinics were perceived by patients as punitive, including pill-counts and increased frequency of clinic visits. Community leaders felt responsible for young peoples' health, sometimes attempting to influence their treatment-taking by threatening to withdraw services, or to publically "out" those deemed to be non-adherent. At home, discussions with adolescents about HIV were often limited to dose reminders, and some caretakers resorted to physical punishment to ensure adherence. While some adolescents complied with strictly-enforced adherence rules, others demonstrated resistance by hiding missed doses, secretly throwing away drugs, or openly refusing to take them.

CONCLUSIONS

The potential of young people to adhere to their ART may be undermined by restrictive messages and punitive approaches to enforce and control their engagement with treatment at home, in the clinic and in the wider community. Interventions should focus on creating safe spaces for adolescents to speak frankly about the adherence challenges that they face and support for caregivers including home-based interventions.

Overview of systematic reviews on strategies to improve treatment initiation, adherence to antiretroviral therapy and retention in care for people living with HIV: part 1

OBJECTIVES

We sought to map the evidence and identify interventions that increase initiation of antiretroviral therapy, adherence to antiretroviral therapy and retention in care for people living with HIV at high risk for poor engagement in care.

METHODS

We conducted an overview of systematic reviews and sought for evidence on vulnerable populations (men who have sex with men (MSM), African, Caribbean and Black (ACB) people, sex workers (SWs), people who inject drugs (PWID) and indigenous people). We searched PubMed, Excerpta Medica dataBASE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Web of Science and the Cochrane Library in November 2018. We screened, extracted data and assessed methodological quality in duplicate and present a narrative synthesis.

RESULTS

We identified 2420 records of which only 98 systematic reviews were eligible. Overall, 65/98 (66.3%) were at low risk of bias. Systematic reviews focused on ACB (66/98; 67.3%), MSM (32/98; 32.7%), PWID (6/98; 6.1%), SWs and prisoners (both 4/98; 4.1%). Interventions were: mixed (37/98; 37.8%), digital (22/98; 22.4%), behavioural or educational (9/98; 9.2%), peer or community based (8/98; 8.2%), health system (7/98; 7.1%), medication modification (6/98; 6.1%), economic (4/98; 4.1%), pharmacy based (3/98; 3.1%) or task-shifting (2/98; 2.0%). Most of the reviews concluded that the interventions effective (69/98; 70.4%), 17.3% (17/98) were neutral or were indeterminate 12.2% (12/98). Knowledge gaps were the types of participants included in primary studies (vulnerable populations not included), poor research quality of primary studies and poorly tailored interventions (not designed for vulnerable populations). Digital, mixed and peer/community-based interventions were reported to be effective across the continuum of care.

CONCLUSIONS

Interventions along the care cascade are mostly focused on adherence and do not sufficiently address all vulnerable populations.

iSAY (incentives for South African youth): Stated preferences of young people living with HIV

High adherence to antiretroviral therapy (ART) is essential for achieving viral suppression and preventing HIV transmission. Yet adherence is suboptimal among adolescents who face unique adherence challenges. Little is known about the role of conditional economic incentives (CEIs) for increasing ART adherence in this population. During 2017-2019, we conducted a mixed-methods discrete choice experiment in Cape Town, South Africa to inform the optimal design of a CEI intervention for ART adherence among youth. In-depth interviews were conducted with n = 35 adolescents (10-19 years old) living with HIV and prescribed ART, to identify attributes of a youth-centered CEI intervention for ART adherence. A discrete choice experiment was subsequently conducted with N = 168 adolescents to elicit preferences for intervention components. A rank-ordered mixed logit model was used for main results; marginal willingness-to-accept (mWTA) was then estimated. Five attributes emerged from the qualitative research as important for a CEI-based intervention for youth ART adherence: (1) incentive amount, (2) incentive format, (3) incentive recipient, (4) delivery mode, and (5) program participants. Youth had a high probability of acceptance of any incentives program (88-100%), yet they did not have a strong preference of a quarterly over a monthly program. From a maximum incentive amount of R1920 (~US$115), youth were willing to forgo up to R126 per year (~US$9) if the incentive was given in cash (versus fashion vouchers); R274 (~US$19.6) if it was open to both previously adherent and non-adherent youth (instead of non-adherent only); and up to R91 (~US$6.5) to receive incentives at a clinic setting (instead of electronically). The use of incentives over the short term during the critical age- and developmental-transition, when adolescents begin to take sole responsibility for their medication-taking behaviors, holds great promise for habituating adherence into adulthood.

Longitudinal evaluation of adherence, retention, and transition patterns of adolescents living with HIV in Nigeria

Introduction

Adherence to antiretroviral therapy (ART) and retention in treatment programs are required for successful virologic suppression and treatment outcomes. As the number of adolescents living with HIV continues to increase globally, more information about adherence and retention patterns during and through transition from child- to adult-centered care is needed to ensure provision of a high level of care and inform development of targeted interventions to improve patient outcomes in this vulnerable population. In this analysis, we sought to describe long-term trends in adherence, retention, and virologic suppression in adolescents receiving ART at a pediatric HIV clinic in Nigeria through transition to the adult clinic.

Setting

The Jos University Teaching Hospital, United States President’s Emergency Plan for AIDS Relief (PEPFAR)-funded HIV clinic in Jos, Plateau State, Nigeria.

Methods

We conducted a retrospective observational longitudinal evaluation of data that had been collected during the course of care in a large pediatric ART program in Nigeria. We used descriptive statistics to define our patient population and quantify retention from ART initiation through adolescence and transition to adult-centered care. Logistic regression was used to evaluate predictors of loss to follow-up. We used medication possession ratio (MPR) to quantify adherence for each year a patient was on ART. To evaluate adherence and virologic suppression, we measured the proportion of patients with ≥95% MPR and the proportion with virologic suppression (viral load ≤400 copies/mL) within each age cohort, and used bivariate analyses to examine any association between MPR and VL suppression for all person-years observed.

Results

A total of 476 patients received at least one dose of ART as an adolescent (ages 10–19 years). The proportions of patients lost to follow-up were: 11.9% (71/597) prior to adolescence, 19.1% (31/162) during adolescence, and 13.7% (10/73) during transition to adult-centered care. While over 80% of patients had ≥95% medication adherence in all age groups, their viral load suppression rates through adolescence and post-transition were only 55.6%–64.0%. For patients that successfully transitioned to adult-centered care, we observed 87.7% (50/57) retention at month 12 post-transition, but only 34.6% (9/26) viral load suppression.

Conclusions

Our evaluation found considerable proportions of adolescents lost to follow-up throughout the ART program cascade. We also found discrepancies between the proportions of patients with ≥95% MPR and the proportions with VL suppression, suggesting that true medication adherence in this population may be poor. Significant attention and targeted interventions to improve retention and adherence focused on adolescents are needed in order for global programs to achieve 90-90-90 goals.

The Perspectives of Adolescents and Young Adults on Adherence to Prophylaxis in Hemophilia: A Qualitative Study

PURPOSE

Adolescents and young adults (AYAs) with severe hemophilia use prophylaxis that requires a high level of adherence. The present study aimed to explore the underlying reason for adherence and non-adherence to prophylaxis in hemophilia from the perspective of AYAs.

PATIENTS AND METHODS

A qualitative study in Dutch AYAs with hemophilia (14-25 years) using prophylaxis was executed. Focus group interviews and individual interviews were recorded, transcribed, coded and analyzed using an iterative process. Member checking in three respondents was used to validate the potential model.

RESULTS

A total of 21 interviews were performed. Parental support decreased when AYAs gained more treatment responsibilities, which resulted in a higher risk for non-adherence. AYAs were weighing their potential bleeding risk per activity based on the wish to do what they prefer while also wanting to simultaneously feel safe. When bleeding with low impact on their daily life occurred, or when bleeding remained absent, AYAs felt safe and the perceived need for prophylaxis decreased.

CONCLUSION

The level of treatment responsibility per AYA and estimated risks per activity were the two main underlying reasons for (non-)adherence.

CLINICAL IMPLICATIONS

We suggest using a conversation technique to discuss adherence, especially during bleeding assessment visits.

Analysis of Systematic Reviews of Medication Adherence Interventions for Persons with HIV, 1996-2017

This overview of reviews summarizes the evidence from systematic reviews (SR) on the effectiveness of antiretroviral therapy (ART) adherence interventions for people with HIV (PWH) and descriptively compares adherence interventions among key populations. Relevant articles published during 1996-2017 were identified by comprehensive searches of CDC's HIV/acquired immunodeficiency syndrome (AIDS) Prevention Research Synthesis Database and manual searches. Included SRs examined primary interventions intended to improve ART adherence, focused on PWH, and assessed medication adherence or biologic outcomes (e.g., viral load). We synthesized the qualitative data and used the Assessment of Multiple Systematic Reviews (AMSTAR) for quality assessment. Forty-one SRs met inclusion criteria. Average quality was high. SRs that evaluated text-messaging interventions (n = 9) consistently reported statistically significant improvements in adherence and biologic outcomes. Other ART adherence strategies [e.g., behavioral, directly administered antiretroviral therapy (DAART)] reported improvements, but did not report significant effects for both outcomes, or intervention effects that did not persist postintervention. In the review focused on people who inject drugs (n = 1), DAART alone or in combination with medication-assisted therapy improved both outcomes. In SRs focused on children or adolescents aged <18 years (n = 5), regimen-related and hospital-based DAART improved biologic outcomes. ART adherence interventions (e.g., text-messaging) improved adherence and biologic outcomes; however, results differed for other intervention strategies, populations, and outcomes. Because few SRs reported evidence for populations at high risk (e.g., men who have sex with men), the results are not generalizable to all PWH. Future implementation studies are needed to examine medication adherence interventions in specific populations and address the identified gaps.

Vivências de jovens em terapia antirretroviral para o HIV: estudo fenomenológico

Objetivo: compreender as vivências de jovens quanto ao uso da terapia antirretroviral para o HIV.Método: trata-se de uma investigação fenomenológica, fundamentada no referencial teórico-filosófico-metodológico de Martin Heidegger. Foram desenvolvidas entrevistas com dez jovens (16 a 23 anos), em serviço de referência na Região Sul do Brasil.Resultados: as unidades de significados foram: 1. Medo de contar o diagnóstico e de morrer, justificado nas experiências familiares ou sociais; 2. Tomar os remédios é complicado, mas tem que tomar para ficar bem e cuidar do outro e para isso, buscam estratégias; e, de modo contraditório, 3. Tomar os medicamentos é algo normal, tornando a vida diferente. A hermenêutica desvela o modo de ser-com, nas relações que estabelecem com as pessoas que confiam. Apresentaram temor devido à possibilidade do preconceito e da morte. No modo da ambiguidade, expressam que tomar os medicamentos é complicado e também normal, tornando a vida diferente. E, no falatório em que todas as informações parecem ter sido compreendidas, quando na verdade não foram, então os jovens repetem aquilo que escutam dos profissionais e continuam curiosos.Conclusões: concluímos que é necessário um cuidado que fortaleça as estratégias e a rede de apoio para manter o tratamento.

HIV care continuum among newly diagnosed student and non-student youths between 2012 and 2016 in Hangzhou, China

BACKGROUND

Youths are disproportionally affected by the human immunodeficiency virus (HIV) infection. We aimed to assess anti-retroviral therapy (ART) initiation and viral suppression rates among student and non-student youths in Hangzhou, China.

METHODS

Data were taken from the Chinese HIV/acquired immune deficiency syndrome Comprehensive Response Information Management System. Youths aged 15 to 24 years who were newly diagnosed with HIV between 2012 and 2016 and were living in Hangzhou were included in the study. Comparisons between student and non-student youths were made for ART initiation within 30 days, 90 days, and 12 months of HIV diagnosis, and the viral suppression rate at 12 months of HIV diagnosis and at 12 months of ART initiation.

RESULTS

A total of 707 cases met inclusion criteria, 29.6% of which were students and 70.4% were non-student youths. The student group had a higher proportion of ART initiation compared with the non-student group within 30 days of diagnosis (45.5% vs. 37.0%, P = 0.044), and a slightly higher but not statistically significant proportion at 90 days (67.0% vs. 62.7%), and 12 months (83.7% vs. 78.5%) of HIV diagnosis. ART initiation within 30 days improved from <15% in 2012 to over 65% in 2016 in both groups, and ART initiation within 90 days improved from <30% in 2012 to >90% in 2016. A smaller proportion of students experienced viral suppression compared with the non-student group (9.6% vs. 17.1%, P = 0.011) at 12 months after HIV diagnosis, but the suppression rate was similar at 12 months of ART initiation (69.9% vs. 71.1%, P = 0.743).

CONCLUSIONS

ART initiation in both student and non-student youths has significantly improved between 2012 and 2016. However, the viral suppression rate remained unacceptably low at 12 months of HIV diagnosis in both student and non-student groups. Specific intervention strategies must be taken to address this challenge.

Challenges faced by caregivers of virally non-suppressed children on the intensive adherence counselling program in Uganda: a qualitative study

Background

Of the estimated 130,000 children living with HIV in Uganda, 47% are receiving ART. Only 39.3% have suppressed HIV-1 viral load to levels below 50 copies per ml. Caregivers are key drivers of adherence to achieve viral suppression in children. We investigated the challenges and potential support required by caregivers of ART-treated children.

Methods

A qualitative study was conducted within the Infectious Diseases Institute paediatric ART program in Kampala and Hoima districts. Caregivers of children with viral loads above 1000 copies were purposively sampled and engaged in five focus group discussions (FGD). The FGD guide highlighted questions on challenges that caregivers face and the kind of support they required to improve children’s ART adherence. Thematic analysis using the inductive approach was used. All the transcripts were read, coded and emergent themes determined.

Results

Overall, 37 caregivers participated in five FGD, of whom 29 (78%) were female, 28 (76%) were HIV-infected and 25 (68%) were biological parents of the children. The elicited challenges were either in failure to attend the counselling sessions or in supporting adherence to medication. Individual and health system challenges such as competing priorities, logistics, poor quality of counselling and lack of reminders prevented attendance at counselling sessions. Five themes emerged as challenges to supporting adherence: i) environmental (school activities, working away from home), ii) personal (non-disclosure, stigma), iii) psychological (guilt), iv) financial (lack of food and transport) and v) child-related (fatigue and peer influence). Three major themes emerged for the support that caregivers needed namely: a) health system reforms (clinic appointments outside school hours, minimize ART drug stock outs and improve quality of counselling), b) psychosocial support (support with disclosure of HIV status to children and their families, more frequent peer support groups and parenting classes) and c) economic empowerment (training in vocational skills, school fees support and opportunities to initiate income generating activities).

Discussion and conclusion

To achieve viral suppression, ART programs require targeted efforts to provide specific health facility requirements, psychological and economic needs of ART-treated children and their caregivers. Integration of HIV treatment with programs for orphans and vulnerable children may improve viral suppression rates.

Effects of antiretroviral therapy in HIV-positive adults on new HIV infections among young women: a systematic review protocol

BACKGROUND

The HIV/AIDS pandemic has struck regions, countries, and populations in different ways. With the introduction of antiretroviral drugs, people living with HIV (PLHIV) have a much better prognosis, even though there are still many new infections in young women. The role of widespread antiretroviral therapy (ART) on the incidence of HIV in young women is unknown.

METHODS

We will conduct a comprehensive search of MEDLINE (PubMed), Excerpta Medica database (EMBASE), Scopus, Google Scholar, Cochrane Central Register of Controlled Trials (CENTRAL), World Health Organization's (WHO's) library database, Latin American and Caribbean Health Sciences Literature (LILACS), conference abstracts, and gray literature sources to identify any relevant literature. We will include randomized and non-randomized clinical trials and cohort studies in which ART was offered to adults aged 18 and above reporting outcomes in females aged 15 to 24 years. The outcomes of interest are HIV incidence, ART initiation, adherence, retention, and viral load suppression. We will screen titles, abstracts, and the full texts of relevant articles in duplicate. Disagreements will be resolved by consensus. We will extract data on the risk of HIV infection in younger females after the use of ART in the adult population.

DISCUSSION

To our knowledge, this is the first systematic review to look at the impact of ART use among adults on HIV incidence in young women. The results of this review will be used in a modeling study to simulate the effects of using ART as an effective tool to prevent sexual transmission of HIV to young women. Our findings will inform the treatment-as-prevention (TasP) strategy to reduce new HIV infections among young women.

The Supporting Adolescent Adherence in Vietnam (SAAV) study: study protocol for a randomized controlled trial assessing an mHealth approach to improving adherence for adolescents living with HIV in Vietnam

BACKGROUND

The overall goal of the Supporting Adolescent Adherence in Vietnam (SAAV) study is to improve understanding of an adherence feedback mHealth intervention designed to help adolescents living with HIV (ALHIV) maintain high adherence to antiretroviral therapy (ART), critical to effective treatment. Specifically, we aim to: (1) conduct formative research with Vietnamese ALHIV and their caregivers to better understand adherence challenges and refine the personalized mHealth intervention package; and (2) assess the feasibility, acceptability, and efficacy of the intervention to improve ART adherence by implementing a randomized controlled trial (RCT).

METHODS

The study will utilize mixed methods. The formative phase will include 40 in-depth interviews (IDIs) with 20 adolescent (12-17 years)/caregiver dyads and eight focus group discussions with adolescents, caregivers, and clinicians at the National Hospital for Pediatrics (NHP) in Hanoi, Vietnam. We will also conduct 20 IDIs with older adolescents (18-21 years) who have transitioned to adult care at outpatient clinics in Hanoi. We will then implement a seven-month RCT at NHP. We will recruit 80 adolescents on ART, monitor their adherence for one month to establish baseline adherence using a wireless pill container (WPC), and then randomize participants to intervention versus control within optimal (≥ 95% on-time doses) versus suboptimal (< 95% on-time doses) baseline adherence strata. Intervention participants will receive a reminder of their choice (cellphone text message/call or bottle-based flash/alarm), triggered when they miss a dose, and engage in monthly counseling informed by their adherence data. Comparison participants will receive usual care and offer of counseling at routine monthly clinic visits. After six months, we will compare ART adherence, CD4 count, and HIV viral suppression between arms, in addition to acceptability and feasibility of the intervention.

DISCUSSION

Findings will contribute valuable information on perceived barriers and facilitators affecting adolescents' ART adherence, mHealth approaches as adherence support tools for ALHIV, and factors affecting adolescents' ART adherence. This information will be useful to researchers, medical personnel, and policy-makers as they develop and implement adherence programs for ALHIV, with potential relevance to other chronic diseases during transition from adolescent to adult care.

Challenges and support for quality of life of youths living with HIV/AIDS in schools and larger community in East Africa: a systematic review

BACKGROUND

Youths living with HIV/AIDS (YLWHA) experience innumerable challenges within schools and the larger community. Nonetheless, these environments are potential sources of support for such youths. This review provides a synthesis of evidence about these challenges and support available for YLWHA to inform the design and implementation of interventions that support the wellbeing of youths living with HIV/AIDS in an East African context.

METHODS

We searched MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, and Cochrane central registry of systematic reviews and randomized control trials for studies conducted in East Africa and published in English in the last 10 years (March 2007 to March 2017). We also searched Google Scholar and reference lists of all included studies. We purposed to include both qualitative and quantitative data but no quantitative data merited inclusion. We analyzed qualitative data using a framework thematic analysis.

RESULTS

We included 16 primary studies conducted in clinic and community settings that used qualitative or mixed methods. Three overarching themes-psychosocial wellbeing, treatment and health, and disclosure of HIV status together with a sub-theme of stigma that was important across the three overarching themes-were the basis for analysis. In each overarching theme, a duality of challenges versus support was reported. Psychosocial wellbeing included subthemes of challenges in schools and larger community, financial challenges, domestic violence, sexual and reproductive health challenges, and psychosocial support.

CONCLUSION

YLWHA experience numerous challenges and support needs, some of which occur in schools and affect their QoL. The effects of these challenges are poor health and educational outcomes as well as school dropout. The schools in which youths spend most of their formative years have not provided adequate support for YLWHA. This review identified that although most of the challenges that studies identified arose from within schools and that a few supportive approaches were available, none of the studies explored how these supportive approaches would work in schools. It was additionally identified that stigma complicates challenges of living with HIV/AIDS necessitating interventions for the wellbeing of YLWHA to understand and address HIV-stigma and its ramifications. Such interventions ought to be sustainable in schools, culturally appropriate, and multidisciplinary in order to promote the general health of all students.

Enhancing health among youth living with HIV using an iPhone game

BACKGROUND

Despite promising outcomes of antiretroviral therapy (ART), challenges to improving adherence among youth living with HIV (YLWH) exist. Mobile games are popular among youth and may improve skills related to resilience, coping, and ART adherence. This study examines the preliminary effects of an iPhone game/app on ART adherence, viral load, and relevant knowledge and attitudes among YLWH in Jackson, MS.

METHODS

A RCT with 61 YLWH tested the impact of BattleViro, an ART-related iPhone game, over 16 weeks. Participants, ages 14-26, were recruited from HIV clinics and randomly assigned to receive BattleViro or a non-HIV-related game. All participants received a medication monitoring device. Chi-square and t-test analyses examined baseline differences between conditions. Continuous outcomes were examined using analyses of covariance (ANCOVAs) controlling for baseline scores. Cohen's d effect size differences (ESD) between groups were calculated.

RESULTS

The sample was 79% male, 97% Black, and 74% non-heterosexual, with a mean age of 22 years. A third had started ART in the past 3 months. There were no demographic differences between conditions. Examination of ESDs revealed that BattleViro demonstrated promising, but nonsignificant, improvements in HIV knowledge (ESD = 0.50), ART knowledge (ESD = 0.42) and social support (ESD = 0.62). Exploratory moderation analyses revealed interactions between BattleViro and newly starting ART. Those newly starting ART in the BattleViro condition, compared to those in the control, experienced a 0.96 log greater decrease in viral load (ESD=-2.21, F = 4.33, p = 0.04), better adherence (71% vs. 48%; ESD = 1.15, F = 3.90, p = 0.05), more HIV knowledge (ESD = 0.90), and more ART knowledge (ESD = 0.72).

CONCLUSION

BattleViro showed promising improvements in HIV knowledge, ART knowledge and social support. Also, there was improved adherence and viral load outcomes specifically among those newly starting ART. ART initiation may be an opportunity to empower and motivate YLWH to build healthy skills.

Adoption of routine virologic testing and predictors of virologic failure among HIV-infected children on antiretroviral treatment in western Kenya

BACKGROUND

Access to routine virologic monitoring, critical to ensuring treatment success, remains limited in low- and middle-income countries. We report on implementation of routine viral load (VL) monitoring and risk factors for virologic failure among HIV-infected children on antiretroviral treatment (ART) in Western Kenya.

METHODS

Routine VL testing was introduced in western Kenya in November 2013. We performed a case-control study among 1190 HIV-infected children ≤15 years on ART who underwent routine VL testing June 2014-May 2015. A random sample of 98 cases (virologic failure define as VL >1000 cps/mL) and 201 controls (VL <1000 cps/mL) from five facilities in three high HIV prevalence counties in Kenya were followed for a minimum of 12 months. Data from patient charts were analyzed using logistic regression to determine factors associated with failure to attain virologic suppression at initial routine and subsequent VL testing among cases.

RESULTS

Overall, 1190 (94%) children with a median age of 8 years underwent routine VL testing of whom (37%) had virological failure. Among the 299 cases and controls, WHO stage, baseline CD4 count and time since ART initiation were not associated with virologic failure during the follow-up period. In multivariable analysis, unsuppressed children at initial test were more likely to be male (adjusted Odds Ratio (aOR) 2.1, 95% Confidence Interval (CI) 2.1-3.6) and have had an ART regimen change (aOR 2.0, CI 1.0-3.7) than controls. Of the two-thirds of children 201/299 who had a subsequent VL performed, VL suppression was greater among those suppressed at initial test 126/135 (93.3%) compared to children with virologic failure 15/66 (22.7%, p<0.0001). Among those failing at first test who achieved viral suppression in follow up, 12/15 (80%) were on a protease inhibitor (PI)-based regimen. In the multivariable analysis of children with subsequent VL testing, children on PI-based 2nd line regimens were 10-fold more likely to achieve viral suppression than children on first-line NNRTI-based ART (adjusted Odds Ratio [aOR] 0.1; 95%CI 0.0-0.4).

CONCLUSION

Coverage of initial routine viral load testing among children on ART in western Kenya is high. However, subsequent testing and virologic suppression are low in children with virologic failure on initial routine viral load test. There is an urgent need to improve management and viral load monitoring of children living with HIV experiencing treatment failure to ensure improved long-term outcomes.

Effectiveness of short message services and voice call interventions for antiretroviral therapy adherence and other outcomes: A systematic review and meta-analysis

BACKGROUND

The potential of using mobile phone technologies to improve antiretroviral therapy (ART) adherence has provided a new facet to human immunodeficiency virus (HIV) research. The quality of evidence and the strength of recommendations of existing reviews, however, do not adequately support large-scale adoption of the intervention. This review adopted broad selection criteria to include all mobile phone-based interventions designed to improve patient's adherence to ART.

METHODS

We performed a systematic review and meta-analysis of randomized controlled trials and quasi-experimental studies. PUBMED, MEDLINE, EMBASE, PsychINFO, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, AMED and Web of Science were searched. Online abstracts archives of relevant conference proceedings and trial registries were also searched. Thirty-Five (35) full-text articles were assessed for eligibility. Included studies were conducted in high, low and middle-income countries and reported ART adherence interventions delivered by mobile phones (standard or smartphones) in the form of voice calls, interactive voice response calls (IVR), and short message service (SMS).

RESULTS

Thirteen (13) studies met the inclusion criteria, and 11 were used in the meta-analysis. Intervention characteristics of included studies ranged from mobile phone functionalities to provision of study phones to participants. SMS and voice call contents were tailored to participants' specific adherence needs. Mobile SMS interventions improved adherence to ART compared with control conditions (OR, 95% CI = 1.59, 1.27-1.98). In subgroup analysis, only scheduled SMS was significant whereas triggered SMS had no effect on adherence to ART. Mobile voice calls did not significantly increase adherence to ART. The interventions were highly rated by > 90% of participants in the studies that reported on the experiences and satisfaction with the intervention.

CONCLUSION

Scheduled mobile phone text-messaging have demonstrated significant improvement in adherence to ART. Mobile SMS adherence interventions that allow for two-way communication may, however, be more acceptable than standalone SMS reminders, which are seen to be intrusive, producing habituation and response fatigue. Voice calls and triggered SMS functionalities do not have a significant effect on adherence to ART although there is a higher preference for voice functionality over SMS especially in limited-resource and low-literacy settings. Further exploration of the mobile voice functionality and its possible combination with scheduled SMS functionality is recommended. Evidence provided in this study will guide the implementation of mobile phone intervention to improve adherence to ART, by addressing practical challenges that could militate against scalability especially in resource limited settings.

The role of community health workers in improving HIV treatment outcomes in children: lessons learned from the ZENITH trial in Zimbabwe

Reliance on community health workers (CHWs) for HIV care continues to increase, particularly in resource-limited settings. CHWs can improve HIV service use and adherence to treatment, but effectiveness of these programmes relies on providing an enabling work environment for CHWs, including reasonable workload, supportive supervision and adequate training and supplies. Although criteria for effective CHW programmes have been identified, these have rarely been prospectively applied to design and evaluation of new interventions. For the Zimbabwe study for Enhancing Testing and Improving Treatment of HIV in Children (ZENITH) randomized controlled trial, we based our intervention on an existing evidence-based framework for successful CHW programmes. To assess CHWs’ experiences delivering the intervention, we conducted longitudinal, qualitative semi-structured interviews with all 19 CHWs at three times during implementation. The study aimed to explore CHWs’ perceptions of how the intervention’s structure and management affected their performance, and consider implications for the programme’s future scale-up and adoption in other settings. CHWs expressed strong motivation, commitment and job satisfaction. They considered the intervention acceptable and feasible to deliver, and levels of satisfaction rose over interview rounds. Intensive supervision and mentoring emerged as critical to ensuring CHWs’ long-term satisfaction. Provision of job aids, standardized manuals and refresher training were also important, as were formalized links between clinics and CHWs. Concerns raised by CHWs included poor remuneration, their reluctance to stop providing support to individual families following the requisite number of home visits, and disappointment at the lack of programme sustainability following completion of the trial. Furthermore, intensive supervision and integration with clinical services may be difficult to replicate outside a trial setting. This study shows that existing criteria for designing successful CHW programmes are useful for maximizing effectiveness, but challenges remain for ensuring long-term sustainability of ‘task shifting’ strategies.

Low HIV viral suppression rates following the intensive adherence counseling (IAC) program for children and adolescents with viral failure in public health facilities in Uganda

Background

The UNAIDS 90–90-90 strategy clearly stipulates that 90% of all people on antiretroviral therapy (ART) should have a suppressed viral load. Intensified adherence counselling (IAC) was recently recommended by WHO to improve viral suppression among ART-treated paediatric and adolescent clients with virological failure. This paper describes the implementation and outcomes of IAC in the first year of implementation in a public ART program, to inform strategic interventions to reach the “third 90” among children.

Methods

A retrospective chart review was conducted for all children aged 9 months to 19 years with HIV viral loads (VL) ≥ 1000 copies/ml at 15 public health facilities from June 2015–December 2016. Data on initial VL test results, IAC sessions, repeat VL test results, and ART regimen switch were abstracted and analysed for completion of IAC and viral suppression after IAC.

Results

A total of 449 children had a detectable viral load above 1000 copies/ml, after an average of 3.5 years (SD 5.8) years of ART. 192 (43%) were 10–20 years of age, and 320 (71%) were receiving Nevirapine-based ART regimen. Out of 345 (77%) who completed the recommended three IAC sessions, 62 (23%) achieved viral suppression following IAC. The mean time from 1st to 3rd IAC session was 113 (SD 153) days and 172 (50%) of the children had completed the three sessions within 200 days.

Conclusion

Suppression rates were low among ART-treated children with virological failure that completed the recommended three IAC sessions. As we move towards having 90% of ART-treated children and adolescents achieve and maintain viral suppression, there is need to re-evaluate the implementation of IAC among children and adolescents to consider both psychosocial and biological factors such as resistance testing for those with multiple detectable viral loads.

Adherence to Highly Active Antiretroviral Therapy Among Children in Ethiopia: A Systematic Review and Meta-analysis

Adherence to highly active antiretroviral therapy (HAART) is the mainstay of the strategy in reducing morbidity and mortality of HIV-infected children. Different primary studies were conducted in Ethiopia. Thus, we aimed to conduct a meta-analysis of the national prevalence of optimal adherence to HAART in children. In addition, associated factors of HAART adherence were reviewed. A weighted inverse variance random-effects model was applied. The 88.7 and 93.7% of children were adhering to HAART at 07 and 03 days prior to an interview respectively. The subgroup analysis showed that HAART adherence was 93.4% in Amhara, 90.1% in Addis Ababa and 87.3% in Tigray at 07 days prior to an interview. Our study suggests that, within short window reported time, adherence to HAART in Ethiopian children may be in a good progress. Emphasis on specific adherence interventions need further based on individual predictors to improve overall HAART adherence of children.

A Mobile Gaming Intervention to Increase Adherence to Antiretroviral Treatment for Youth Living With HIV: Development Guided by the Information, Motivation, and Behavioral Skills Model

Background

Highly active combination antiretroviral treatment has been shown to markedly improve the health of HIV-infected adolescents and young adults. Adherence to antiretroviral treatment leads to decreased morbidity and mortality and decreases the number of hospitalizations. However, these clinical achievements can only occur when young persons with HIV are adherent to care. Unfortunately, adolescents and young adults have poorer rates of adherence to antiretroviral medications and poorer rates of retention in care than older adults. Novel and engaging digital approaches are needed to help adolescents and young adults living with HIV be adherent to treatment.

Objective

The aim of this study was to develop an immersive, action-oriented iPhone gaming intervention to improve adherence to antiretroviral medication and treatment.

Methods

Game development was guided by social learning theory, taking into consideration the perspectives of adolescents and young adults living with HIV. A total of 20 adolescents and young adults were recruited from an HIV care clinic in Rhode Island, and they participated in qualitative interviews guided by the information-motivation-behavioral skills model of behavior change. The mean age of participants was 22 years, 60% (12/20) of the participants identified as male, and 60% (12/20) of the sample reported missing a dose of antiretroviral medication in the previous week. Acceptability of the game was assessed with client service questionnaire and session evaluation form.

Results

A number of themes emerged that informed game development. Adolescents and young adults living with HIV desired informational game content that included new and comprehensive details about HIV, details about HIV as it relates to doctors’ visits, and general health information. Motivational themes that emerged were the desire for enhancement of future orientation; reinforcement of positive influences from partners, parents, and friends; collaboration with health care providers; decreasing stigma; and increasing personal relevance of HIV care. Behavioral skills themes centered on self-efficacy and strategies for medical adherence and self-care. On the client service questionnaire, 10 out of the 11 participants indicated they were “satisfied with the game activities,” and 9 out of 11 “would recommend it to a friend.” On the session evaluation form, 9 out of 11 agreed that they “learned a lot from the game.”

Conclusions

We utilized youth feedback, social learning theory (information-motivation-behavioral skills), and agile software development to create a multilevel, immersive, action-oriented iPhone gaming intervention to measure and improve treatment adherence for adolescents and young adults living with HIV. There is a dearth of gaming interventions for this population, and this study is a significant step in working toward the development and testing of an iPhone gaming app intervention to promote adherence to antiretroviral treatment.

Routine viral load monitoring in HIV-infected infants and children in low- and middle-income countries: challenges and opportunities

INTRODUCTION

The objective of this commentary is to review considerations for implementing routine viral load (VL) monitoring programmes for HIV-infected infants and children living in low- and middle-income countries (LMIC). Since 2013, the World Health Organization (WHO) guidelines recommend VL testing as the preferred monitoring approach for all individuals treated with ART in order to assess treatment response, detect treatment failure and determine the need to switch to a second-line regimen in a timely manner. More recently, WHO guidelines from 2016 identify HIV-infected infants and children as a priority group for routine VL monitoring.

DISCUSSION

There are a number of reasons why HIV-infected infants and children should be prioritized for routine VL monitoring. Data from national VL monitoring programmes as well as systematic reviews and meta-analyses from LMIC indicate rates of viral suppression are lower for infants and children compared to adults. The number of antiretroviral drugs and palatable formulations suitable for young children are limited. In addition, emotional and developmental issues particular to children can make daily medication administration difficult and pose a challenge to adherence and achievement of sustained viral suppression. VL monitoring can be instrumental for identifying those in need of additional adherence support, reducing regimen switches and preserving treatment options. The needs of infants and children warrant consideration in all aspects of VL monitoring services. If capacity for paediatric venipuncture is not assured, platforms that accept dried blood spot specimens are necessary in order for infants and children to have equitable access. Healthcare systems also need to prepare to manage the substantial number of infants and children identified with elevated VL, including adherence interventions that are appropriate for children. Establishing robust systems to evaluate processes and outcomes of routine VL monitoring services and to support drug forecasting and supply management is essential to determine best practices for infants and children in LMIC.

CONCLUSIONS

The particular concerns of HIV-infected infants and children warrant attention during all phases of planning and implementation of VL monitoring services. There are a number of key areas, including frequency of monitoring, blood specimen type and adherence challenges, where specific approaches tailored for infants and children may be required.

Interventions to improve antiretroviral therapy adherence among adolescents in low- and middle-income countries: A systematic review of the literature

Introduction

Globally, an estimated 30% of new HIV infections occur among adolescents (15–24 years), most of whom reside in sub-Saharan Africa. Moreover, HIV-related mortality increased by 50% between 2005 and 2012 for adolescents 10–19 years while it decreased by 30% for all other age groups. Efforts to achieve and maintain optimal adherence to antiretroviral therapy are essential to ensuring viral suppression, good long-term health outcomes, and survival for young people. Evidence-based strategies to improve adherence among adolescents living with HIV are therefore a critical part of the response to the epidemic.

Methods

We conducted a systematic review of the peer-reviewed and grey literature published between 2010 and 2015 to identify interventions designed to improve antiretroviral adherence among adults and adolescents in low- and middle-income countries. We systematically searched PubMed, Web of Science, Popline, the AIDSFree Resource Library, and the USAID Development Experience Clearinghouse to identify relevant publications and used the NIH NHLBI Quality Assessment Tools to assess the quality and risk of bias of each study.

Results and discussion

We identified 52 peer-reviewed journal articles describing 51 distinct interventions out of a total of 13,429 potentially relevant publications. Forty-three interventions were conducted among adults, six included adults and adolescents, and two were conducted among adolescents only. All studies were conducted in low- and middle-income countries, most of these (n = 32) in sub-Saharan Africa. Individual or group adherence counseling (n = 12), mobile health (mHealth) interventions (n = 13), and community- and home-based care (n = 12) were the most common types of interventions reported. Methodological challenges plagued many studies, limiting the strength of the available evidence. However, task shifting, community-based adherence support, mHealth platforms, and group adherence counseling emerged as strategies used in adult populations that show promise for adaptation and testing among adolescents.

Conclusions

Despite the sizeable body of evidence for adults, few studies were high quality and no single intervention strategy stood out as definitively warranting adaptation for adolescents. Among adolescents, current evidence is both sparse and lacking in its quality. These findings highlight a pressing need to develop and test targeted intervention strategies to improve adherence among this high-priority population.

Systematic review of risk factors for nonadherence to TB treatment in immigrant populations

BACKGROUND

Foreign-born populations carry a significant TB burden in low-prevalence countries, composing over half of all cases in parts of Europe and North America. This study systematically reviewed evidence of risk factors for nonadherence to TB drug therapy in this group.

METHODS

On 28 October 2013 MEDLINE, CINAHL, Embase, PsychINFO and ProQuest were systematically searched for studies examining adherence in foreign-born populations with TB. Grey literature and reference lists were hand-searched. Risk factor studies were selected for inclusion if they consisted of at least 95% foreign-born populations.

RESULTS

Of 1761 studies identified in the search, 20 were included in the risk factor review. Undocumented immigration status, older age, and social risk factors were consistently correlated with nonadherence; gender, ethnicity, immigration time, education level, adverse side effects, and HIV status were inconsistently correlated; and behavioural risk factors and marital status were consistently not correlated.

CONCLUSIONS

This review emphasizes documentation status as a risk factor candidate for further investigation.

Video observations of treatment administration to children on antiretroviral therapy in rural KwaZulu-Natal

For children younger than five years, caregivers are responsible for the measurement and administration of antiretroviral medication doses to children. Failure to adhere to the regimen as prescribed may lead to high viral loads (VLs), immune suppression and ultimately drug resistance. In the content of this study, adherence refers to adequate dosing of the medication by a caregiver. Acquired drug resistance to antiretroviral therapy (ART) is prevalent amongst children in South Africa, and poor adherence to the dosing regimen by caregivers may be associated with this problem. In this qualitative study, we purposively recruited 33 caregiver–child dyads from the Hlabisa HIV Treatment and Care Programme database. Children were divided into three groups based on their VL at the time of recruitment. Children with a VL ≥ 400 cps/ml were grouped as unsuppressed (n = 11); children with a VL ≤ 400 cps/ml were grouped as suppressed (n = 12); and children with no VL data were grouped as newly initiated (n = 10). Caregiver–child dyads were visited at their households twice to document, by means of video recording, how treatment was administered to the child. Observational notes and video recordings were entered into ATLAS.ti v 7 and analysed thematically. Results were interpreted through the lens of Ecological Systems Theory and the information–motivation–behavioural skills model was used to understand and reflect on several of the factors influencing adherence within the child’s immediate environment as identified in this study. Thematic video analysis indicated context- and medication-related factors influencing ART adherence. Although the majority of children in this sample took their medicine successfully, caregivers experienced several challenges with the preparation and administration of the medications. In the context of emerging drug resistance, efforts are needed to carefully monitor caregiver knowledge of treatment administration by healthcare workers during monthly clinic visits.

Improving antiretroviral therapy adherence in resource-limited settings at scale: a discussion of interventions and recommendations

Introduction: Successful population-level antiretroviral therapy (ART) adherence will be necessary to realize both the clinical and prevention benefits of antiretroviral scale-up and, ultimately, the end of AIDS. Although many people living with HIV are adhering well, others struggle and most are likely to experience challenges in adherence that may threaten virologic suppression at some point during lifelong therapy. Despite the importance of ART adherence, supportive interventions have generally not been implemented at scale. The objective of this review is to summarize the recommendations of clinical, research, and public health experts for scalable ART adherence interventions in resource-limited settings. Methods: In July 2015, the Bill and Melinda Gates Foundation convened a meeting to discuss the most promising ART adherence interventions for use at scale in resource-limited settings. This article summarizes that discussion with recent updates. It is not a systematic review, but rather provides practical considerations for programme implementation based on evidence from individual studies, systematic reviews, meta-analyses, and the World Health Organization Consolidated Guidelines for HIV, which include evidence from randomized controlled trials in low- and middle-income countries. Interventions are categorized broadly as education and counselling; information and communication technology-enhanced solutions; healthcare delivery restructuring; and economic incentives and social protection interventions. Each category is discussed, including descriptions of interventions, current evidence for effectiveness, and what appears promising for the near future. Approaches to intervention implementation and impact assessment are then described. Results and discussion: The evidence base is promising for currently available, effective, and scalable ART adherence interventions for resource-limited settings. Numerous interventions build on existing health care infrastructure and leverage available resources. Those most widely studied and implemented to date involve peer counselling, adherence clubs, and short message service (SMS). Many additional interventions could have an important impact on ART adherence with further development, including standardized counselling through multi-media technology, electronic dose monitoring, decentralized and differentiated models of care, and livelihood interventions. Optimal targeting and tailoring of interventions will require improved adherence measurement. Conclusions: The opportunity exists today to address and resolve many of the challenges to effective ART adherence, so that they do not limit the potential of ART to help bring about the end of AIDS.

Bottlenecks and opportunities for delivering integrated pediatric HIV services in Nepal

BACKGROUND

In children, integration of HIV in MNCH services has been shown to incr. ease uptake of early infant diagnosis. This article examines bottlenecks and opportunities for scaling up integrated pediatric HIV services in Nepal.

METHODS

This is a descriptive study using both mixed qualitative and quantitative methods, conducted in January 2015 in 19 facilities in five regions of Nepal most affected by HIV epidemic. The qualitative methods comprised in-depth structured interviews with key informants (leadership of The National Center for AIDS and STD Control and National Public Health Laboratory, district management teams, medical officers in charge of health facilities and HIV clinics, frontline staff at antenatal care and HIV clinics and laboratory). The quantitative methods were used to abstract data of HIV-infected pregnant women seen between January and December 2014, HIV-exposed infants aged less than 12 months, and HIV infected children aged less than 15 years who were initiated HIV treatment from 2010 to 2014. Structured tools were used to collect data which were analysed using IBM SPSS.

RESULTS

Of the 19 facilities assessed, 18(98%), 18(98%), 14(75%), and 11(58%) provided prevention of mother-to-child transmission (PMTCT), Expanded Program on Immunization (EPI), pediatric ART and nutrition rehabilitation services, respectively. However, only 1(5%) facility collected onsite dried blood spots (DBS) for PCR HIV testing and 6(32%) facilities provided counselling and referral for DBS. In 2014, of the 121 HIV-exposed infants recorded, only 21(17%) received PCR test. The median turnaround time of the PCR test results was 54 days. Of the 21 records with PCR test, 11(52.5%) were from PMTCT clinics, 7(33%) from Nutritional rehabilitation clinics, and 3(14.5%) from pediatric outpatient clinic.Conversely, 934 children were initiated ART between 2010 and 2014, of which 5% were infants and 29% aged between 1 and 5 years. 298(32%) had comorbidities of which 64% had malnutrition. A total of 534(57%) had tuberculosis (TB) status assessed of which 58(11%) had active TB. Infants had lowest retention (63%), high mortality (17.4%), and loss to follow-up (10.9%).

CONCLUSION

Few facilities collect DBS and few children receive PCR tests with limited linkage to ART. This has led to late ART initiation, comorbidities, including TB coinfections and poor outcomes. The results indicate that there are opportunities for improving HIV case finding among HIV-exposed infants in PMTCT, EPI, TB, and nutrition services if provider initiated testing and counselling at the point of service delivery is institutionalized in these settings.

The Challenge of and Opportunities for Transitioning and Maintaining a Continuum of Care Among Adolescents and Young Adults Living with HIV in Resource Limited Settings

An unprecedented number of youth living with HIV (YLHIV) are aging into adolescence and young adulthood, increasing concerns about the possibility of these youth being lost in the transition from supported care (sometimes in pediatric settings) to more independent healthcare settings and perhaps furthering the emerging disparities in outcomes (e.g., higher nonadherence to treatment, increased morbidity and mortality). In resource-rich settings where there is likely greater recognition of adolescent cognitive and developmental challenges, transitioning YLHIV to adult healthcare has emerged as a major challenge. In resource limited settings (RLS), where the burden of HIV is significant and healthcare resources often stretched, the challenge to move toward healthcare independence and maintain a fluid continuum of care for YLHIV may be the greatest. We review key issues in transitioning YLHIV in RLS, highlighting steps in the transition process, examining evidence where available, and discussing challenges and opportunities to understanding and optimizing outcomes.

Falling through the gaps: how should HIV programmes respond to families that persistently deny treatment to children?

Introduction

Children living with HIV rely on adult caregivers for access to HIV testing and care, including clinical monitoring and adherence to treatment. Yet, many caregivers confront barriers to ensuring children's care, including fear of disclosure of the child's or the parents’ HIV status, competing family demands, fluctuating care arrangements and broader structural factors such as entrenched poverty or alternative beliefs about HIV's aetiology and treatment. Thus, many children are “falling through the gaps” because their access to testing and care is mediated by guardians who appear unable or unwilling to facilitate it. These children are likely to suffer treatment failure or death due to their caregivers’ recalcitrance.

Discussion

This Commentary presents three cases from paediatric HIV services in Zimbabwe that highlight the complexities facing health care providers in providing HIV testing and care to children, and discusses the implications as a child's rights issue requiring both legal and programmatic responses. The cases provide examples of how disagreements between family members about appropriate care, conflicts between a child and caregiver and religious objections to medical treatment interrupt children's engagement with HIV services. In all three cases, no social or legal mechanisms were in place for health staff to intervene and prevent “loss to follow up.”

Conclusions

We suggest that conceptualizing this as a child's rights issue may be a useful way to raise the debate and move towards improved treatment access. Our cases reflect policy failure to facilitate access to children's HIV testing and treatment, and are likely to be similar across international settings. We propose sharing experiences and encouraging dialogue between health practitioners and global advocates for children's right to health to raise awareness that children are the bearers of rights even if they lack legal capacity, and that the failure of either the state or their caregiver to facilitate access to care is in fact a rights violation.

A Randomized Controlled Trial of Personalized Text Message Reminders to Promote Medication Adherence Among HIV-Positive Adolescents and Young Adults

HIV-positive adolescents and young adults often experience suboptimal medication adherence, yet few interventions to improve adherence in this group have shown evidence of efficacy. We conducted a randomized trial of a two-way, personalized daily text messaging intervention to improve adherence to antiretroviral therapy (ART) among N = 105 poorly adherent HIV-positive adolescents and young adults, ages 16-29. Adherence to ART was assessed via self-reported visual analogue scale (VAS; 0-100 %) at 3 and 6-months for mean adherence level and proportion ≥90 % adherent. The average effect estimate over the 6-month intervention period was significant for ≥90 % adherence (OR = 2.12, 95 % CI 1.01-4.45, p < .05) and maintained at 12-months (6 months post-intervention). Satisfaction scores for the intervention were very high. These results suggest both feasibility and initial efficacy of this approach. Given study limitations, additional testing of this intervention as part of a larger clinical trial with objective and/or clinical outcome measures of adherence is warranted.

Adherence to Antiretroviral Therapy Among Children Living with HIV in South India

Adherence to ART, fundamental to treatment success, has been poorly studied in India. Caregivers of children attending HIV clinics in southern India were interviewed using structured questionnaires. Adherence was assessed using a visual analogue scale representing past-month adherence and treatment interruptions >48 h during the past 3 months. Clinical features, correlates of adherence and HIV-1 viral-load were documented. Based on caregiver reports, 90.9 % of the children were optimally adherent. In multivariable analysis, experiencing ART-related adverse effects was significantly associated with suboptimal adherence (p = 0.01). The proportion of children who experienced virological failure was 16.5 %. Virological failure was not linked to suboptimal adherence. Factors influencing virological failure included running out of medications (p = 0.002) and the child refusing to take medications (p = 0.01). Inclusion of drugs with better safety profiles and improved access to care could further enhance outcomes.

Interventions for Enhancing Adherence to Antiretroviral Therapy (ART): A Systematic Review of High Quality Studies

We sought to review the effectiveness of interventions designed to improve adherence to antiretroviral therapy (ART) from studies included in a recent Cochrane review that reported a clinical and an adherence outcome, with at least 80% follow-up for 6 months or more. Data were extracted independently and in duplicate, with an adjudicator for disagreements. Risk of bias was assessed using the Cochrane Risk of Bias tool. Of 182 relevant studies in the Cochrane review, 49 were related to ART. Statistical pooling was not warranted due to heterogeneity in interventions, participants, treatments, adherence measures and outcomes. Many studies had high risk of bias in elements of design and outcome ascertainment. Only 10 studies improved both adherence and clinical outcomes. These used the following interventions: adherence counselling (two studies); a once-daily regimen (compared to twice daily); text messaging; web-based cognitive behavioral intervention; face-to-face multi-session intensive behavioral interventions (two studies); contingency management; modified directly observed therapy; and nurse-delivered home visits combined with telephone calls. Patient-related adherence interventions were the most frequently tested. Uniform adherence measures and higher quality studies of younger populations are encouraged.

Factors associated with adherence to antiretroviral therapy among adolescents living with HIV/AIDS in low- and middle-income countries: a systematic review

Adolescents living in low- and middle-income countries (LMICs) are disproportionately burdened by the global HIV/AIDS pandemic. Maintaining medication adherence is vital to ensuring that adolescents living with HIV/AIDS receive the benefits of antiretroviral therapy (ART), although this group faces unique challenges to adherence. Knowledge of the factors influencing adherence among people during this unique developmental period is needed to develop more targeted and effective adherence-promoting strategies. This systematic review summarizes the literature on quantitative observational studies examining correlates, including risk and resilience-promoting factors, of ART adherence among adolescents living with HIV/AIDS in LMICs. A systematic search of major electronic databases, conference-specific databases, gray literature, and reference lists of relevant reviews and documents was conducted in May 2014. Included studies examined relationships between at least one factor and ART adherence as an outcome and were conducted in primarily an adolescent population (age 10-19) in LMICs. The search identified 7948 unique citations from which 15 studies fit the inclusion criteria. These 15 studies identified 35 factors significantly associated with ART adherence representing a total of 4363 participants across nine different LMICs. Relevant studies revealed few consistent relationships between measured factors and adherence while highlighting potentially important themes for ART adherence including the impact of (1) adolescent factors such as gender and knowledge of serostatus, (2) family structure, (3) the burdensome ART regimens, route of administration, and attitudes about medication, and (4) health care and environmental factors, such as rural versus urban location and missed clinic appointments. Rates of adherence across studies ranged from 16% to 99%. This review identifies unique factors significantly related to ART adherence among adolescents living in LMICs. More research using longitudinal designs and rigorous measures of adherence is required in order to identify the range of factors influencing ART adherence as adolescents living with HIV/AIDS in LMICs grow into adulthood.

Paediatric European Network for Treatment of AIDS (PENTA) guidelines for treatment of paediatric HIV-1 infection 2015: optimizing health in preparation for adult life

The 2015 Paediatric European Network for Treatment of AIDS (PENTA) guidelines provide practical recommendations on the management of HIV‐1 infection in children in Europe and are an update to those published in 2009. Aims of treatment have progressed significantly over the last decade, moving far beyond limitation of short‐term morbidity and mortality to optimizing health status for adult life and minimizing the impact of chronic HIV infection on immune system development and health in general. Additionally, there is a greater need for increased awareness and minimization of long‐term drug toxicity. The main updates to the previous guidelines include: an increase in the number of indications for antiretroviral therapy (ART) at all ages (higher CD4 thresholds for consideration of ART initiation and additional clinical indications), revised guidance on first‐ and second‐line ART recommendations, including more recently available drug classes, expanded guidance on management of coinfections (including tuberculosis, hepatitis B and hepatitis C) and additional emphasis on the needs of adolescents as they approach transition to adult services. There is a new section on the current ART ‘pipeline’ of drug development, a comprehensive summary table of currently recommended ART with dosing recommendations. Differences between PENTA and current US and World Health Organization guidelines are highlighted and explained.

A review of the role of food insecurity in adherence to care and treatment among adult and pediatric populations living with HIV and AIDS

Adherence to antiretroviral therapy (ART) is critical for reducing HIV/AIDS morbidity and mortality. Food insecurity (FI) is emerging as an important barrier to adherence to care and treatment recommendations for people living with HIV (PLHIV), but this relationship has not been comprehensively examined. Therefore, we reviewed the literature to explore how FI may impact ART adherence, retention in medical care, and adherence to health care recommendations among PLHIV. We found data to support FI as a critical barrier to adherence to ART and to other health care recommendations among HIV-infected adults, HIV-infected pregnant women and their HIV-exposed infants, and child and adolescent populations of PLHIV. Associations between FI and ART non-adherence were seen in qualitative and quantitative studies. We identified a number of mechanisms to explain how food insecurity and ART non-adherence may be causally linked, including the exacerbation of hunger or ART side effects in the absence of adequate food and competing resource demands. Interventions that address FI may improve adherence to care and treatment recommendations for PLHIV.

The economics of medicines optimization: policy developments, remaining challenges and research priorities

BACKGROUND

This review scopes the evidence on the effectiveness and cost-effectiveness of interventions to improve suboptimal use of medicines in order to determine the evidence gaps and help inform research priorities.

SOURCES OF DATA

Systematic searches of the National Health Service (NHS) Economic Evaluation Database, the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects.

AREAS OF AGREEMENT

The majority of the studies evaluated interventions to improve adherence, inappropriate prescribing and prescribing errors.

AREAS OF CONTROVERSY

Interventions tend to be specific to a particular stage of the pathway and/or to a particular disease and have mostly been evaluated for their effect on intermediate or process outcomes.

GROWING POINTS

Medicines optimization offers an opportunity to improve health outcomes and efficiency of healthcare.

AREAS TIMELY FOR DEVELOPING RESEARCH

The available evidence is insufficient to assess the effectiveness and cost-effectiveness of interventions to address suboptimal medicine use in the UK NHS. Decision modelling, evidence synthesis and elicitation have the potential to address the evidence gaps and help prioritize research.

HIV-Infected Individuals Who Delay, Decline, or Discontinue Antiretroviral Therapy: Comparing Clinic- and Peer-Recruited Cohorts

A substantial proportion of persons living with HIV/AIDS (PLHA) delay, decline, or discontinue antiretroviral therapy (ART) when it is medically indicated (40–45%), largely African-Americans and Latinos/Hispanics. This study explores the feasibility of locating PLHA, who are not on ART (PLHA-NOA) through clinics and peer-referral; compares the two cohorts on multi-level barriers to ART; and examines readiness to initiate/reinitiate ART, a predictor of treatment outcomes. We recruited adult HIV-infected African-American and Latino/Hispanic PLHA-NOA through HIV hospital clinics and peer-referral in 2012–2013. Participants were engaged in structured 1-h assessments with reliable/valid measures on barriers to ART. We found that recruitment through peers (63.2%, 60/95) was more feasible than in clinics (36.8%, 35/90). Participants were 48.0 years old and had lived with HIV for 14.7 years on average, and 56.8% had taken ART previously. Most (61.1%) were male and African-American (76.8%), and 23.2% were Latino/Hispanic. Peer-recruited participants were older, had lived with HIV longer, were less engaged in HIV care, and were more likely to have taken ART previously. The cohorts differed in reasons for discontinuing ART. Levels of ART knowledge were comparable between cohorts (68.5% correct), and there were no differences in attitudes toward ART (e.g., mistrust), which were in the neutral range. In bivariate linear regression, readiness for ART was negatively associated with physician mistrust (B = −10.4) and positively associated with self-efficacy (B = 5.5), positive outcome expectancies (B = 6.3), beliefs about personal necessity of ART (B = 17.5), and positive internal norms (B = 7.9). This study demonstrates the feasibility of engaging this vulnerable population through peer-referral. Peer-recruited PLHA evidence particularly high rates of risk factors compared to those in hospital clinics. Interventions to support ART initiation and continuation are sorely needed for both subgroups.

HIV behavioural interventions targeted towards older adults: a systematic review

Background

The increasing number of people living with HIV aged 50 years and older has been recognised around the world yet non-pharmacologic HIV behavioural and cognitive interventions specifically targeted to older adults are limited. Evidence is needed to guide the response to this affected group.

Methods

We conducted a systematic review of the available published literature in MEDLINE, Embase and the Education Resources Information Center. A search strategy was defined with high sensitivity but low specificity to identify behavioural interventions with outcomes in the areas of treatment adherence, HIV testing uptake, increased HIV knowledge and uptake of prevention measures. Data from relevant articles were extracted into excel.

Results

Twelve articles were identified all of which originated from the Americas. Eight of the interventions were conducted among older adults living with HIV and four for HIV-negative older adults. Five studies included control groups. Of the included studies, four focused on general knowledge of HIV, three emphasised mental health and coping, two focused on reduced sexual risk behaviour, two on physical status and one on referral for care. Only four of the studies were randomised controlled trials and seven – including all of the studies among HIV-negative older adults – did not include controls at all. A few of the studies conducted statistical testing on small samples of 16 or 11 older adults making inference based on the results difficult. The most relevant study demonstrated that using telephone-based interventions can reduce risky sexual behaviour among older adults with control reporting 3.24 times (95% CI 1.79-5.85) as many occasions of unprotected sex at follow-up as participants. Overall however, few of the articles are sufficiently rigorous to suggest broad replication or to be considered representative and applicable in other settings.

Conclusions

More evidence is needed on what interventions work among older adults to support prevention, adherence and testing. More methodological rigourised needed in the studies targeting older adults. Specifically, including control groups in all studies is needed as well as sufficient sample size to allow for statistical testing. Addition of specific bio-marker or validated behavioural or cognitive outcomes would also strengthen the studies.

"I don't want financial support but verbal support." How do caregivers manage children's access to and retention in HIV care in urban Zimbabwe?

Introduction

Children living with HIV experience particular challenges in accessing HIV care. Children usually rely on adult caregivers for access to care, including timely diagnosis, initiation of treatment and sustained engagement with HIV services. The aim of this study was to inform the design of a community-based intervention to support caregivers of HIV-positive children to increase children's retention in care as part of a programme introducing decentralized HIV care in primary health facilities.

Methods

Using an existing conceptual framework, we conducted formative research to identify key local contextual factors affecting children's linkages to HIV care in Harare, Zimbabwe. We conducted semi-structured interviews with 15 primary caregivers of HIV-positive children aged 6–15 years enrolled at a hospital clinic for at least six months, followed by interviews with nine key informants from five community-based organizations providing adherence support or related services.

Results

We identified a range of facilitators and barriers that caregivers experience. Distance to the hospital, cost of transportation, fear of disclosing HIV status to the child or others, unstable family structure and institutional factors such as drug stock-outs, healthcare worker absenteeism and unsympathetic school environments proved the most salient limiting factors. Facilitators included openness within the family, availability of practical assistance and psychosocial support from community members.

Conclusions

The proposed decentralization of HIV care will mitigate concerns about distance and transport costs but is likely to be insufficient to ensure children's sustained retention. Following this study, we developed a package of structured home visits by voluntary lay workers to proactively address other determinants such as disclosure within families, access to available services and support through caregivers’ social networks. A randomized controlled trial is underway to assess impact on children's retention in care over two years.

Interventions to improve safe and effective medicines use by consumers: an overview of systematic reviews

BACKGROUND

Many systematic reviews exist on interventions to improve safe and effective medicines use by consumers, but research is distributed across diseases, populations and settings. The scope and focus of such reviews also vary widely, creating challenges for decision-makers seeking to inform decisions by using the evidence on consumers' medicines use.This is an update of a 2011 overview of systematic reviews, which synthesises the evidence, irrespective of disease, medicine type, population or setting, on the effectiveness of interventions to improve consumers' medicines use.

OBJECTIVES

To assess the effects of interventions which target healthcare consumers to promote safe and effective medicines use, by synthesising review-level evidence.

SEARCH METHODS

We included systematic reviews published on the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects. We identified relevant reviews by handsearching databases from their start dates to March 2012.

SELECTION CRITERIA

We screened and ranked reviews based on relevance to consumers' medicines use, using criteria developed for this overview.

DATA COLLECTION AND ANALYSIS

We used standardised forms to extract data, and assessed reviews for methodological quality using the AMSTAR tool. We used standardised language to summarise results within and across reviews; and gave bottom-line statements about intervention effectiveness. Two review authors screened and selected reviews, and extracted and analysed data. We used a taxonomy of interventions to categorise reviews and guide syntheses.

MAIN RESULTS

We included 75 systematic reviews of varied methodological quality. Reviews assessed interventions with diverse aims including support for behaviour change, risk minimisation and skills acquisition. No reviews aimed to promote systems-level consumer participation in medicines-related activities. Medicines adherence was the most frequently-reported outcome, but others such as knowledge, clinical and service-use outcomes were also reported. Adverse events were less commonly identified, while those associated with the interventions themselves, or costs, were rarely reported.Looking across reviews, for most outcomes, medicines self-monitoring and self-management programmes appear generally effective to improve medicines use, adherence, adverse events and clinical outcomes; and to reduce mortality in people self-managing antithrombotic therapy. However, some participants were unable to complete these interventions, suggesting they may not be suitable for everyone.Other promising interventions to improve adherence and other key medicines-use outcomes, which require further investigation to be more certain of their effects, include:· simplified dosing regimens: with positive effects on adherence;· interventions involving pharmacists in medicines management, such as medicines reviews (with positive effects on adherence and use, medicines problems and clinical outcomes) and pharmaceutical care services (consultation between pharmacist and patient to resolve medicines problems, develop a care plan and provide follow-up; with positive effects on adherence and knowledge).Several other strategies showed some positive effects, particularly relating to adherence, and other outcomes, but their effects were less consistent overall and so need further study. These included:· delayed antibiotic prescriptions: effective to decrease antibiotic use but with mixed effects on clinical outcomes, adverse effects and satisfaction;· practical strategies like reminders, cues and/or organisers, reminder packaging and material incentives: with positive, although somewhat mixed effects on adherence;· education delivered with self-management skills training, counselling, support, training or enhanced follow-up; information and counselling delivered together; or education/information as part of pharmacist-delivered packages of care: with positive effects on adherence, medicines use, clinical outcomes and knowledge, but with mixed effects in some studies;· financial incentives: with positive, but mixed, effects on adherence.Several strategies also showed promise in promoting immunisation uptake, but require further study to be more certain of their effects. These included organisational interventions; reminders and recall; financial incentives; home visits; free vaccination; lay health worker interventions; and facilitators working with physicians to promote immunisation uptake. Education and/or information strategies also showed some positive but even less consistent effects on immunisation uptake, and need further assessment of effectiveness and investigation of heterogeneity.There are many different potential pathways through which consumers' use of medicines could be targeted to improve outcomes, and simple interventions may be as effective as complex strategies. However, no single intervention assessed was effective to improve all medicines-use outcomes across all diseases, medicines, populations or settings.Even where interventions showed promise, the assembled evidence often only provided part of the picture: for example, simplified dosing regimens seem effective for improving adherence, but there is not yet sufficient information to identify an optimal regimen.In some instances interventions appear ineffective: for example, the evidence suggests that directly observed therapy may be generally ineffective for improving treatment completion, adherence or clinical outcomes.In other cases, interventions may have variable effects across outcomes. As an example, strategies providing information or education as single interventions appear ineffective to improve medicines adherence or clinical outcomes, but may be effective to improve knowledge; an important outcome for promoting consumers' informed medicines choices.Despite a doubling in the number of reviews included in this updated overview, uncertainty still exists about the effectiveness of many interventions, and the evidence on what works remains sparse for several populations, including children and young people, carers, and people with multimorbidity.

AUTHORS' CONCLUSIONS

This overview presents evidence from 75 reviews that have synthesised trials and other studies evaluating the effects of interventions to improve consumers' medicines use.Systematically assembling the evidence across reviews allows identification of effective or promising interventions to improve consumers' medicines use, as well as those for which the evidence indicates ineffectiveness or uncertainty.Decision makers faced with implementing interventions to improve consumers' medicines use can use this overview to inform decisions about which interventions may be most promising to improve particular outcomes. The intervention taxonomy may also assist people to consider the strategies available in relation to specific purposes, for example, gaining skills or being involved in decision making. Researchers and funders can use this overview to identify where more research is needed and assess its priority. The limitations of the available literature due to the lack of evidence for important outcomes and important populations, such as people with multimorbidity, should also be considered in practice and policy decisions.

Treatment non-adherence in pediatric long-term medical conditions: systematic review and synthesis of qualitative studies of caregivers' views

Background

Non-adherence to prescribed treatments is the primary cause of treatment failure in pediatric long-term conditions. Greater understanding of parents and caregivers’ reasons for non-adherence can help to address this problem and improve outcomes for children with long-term conditions.

Methods

We carried out a systematic review and thematic synthesis of qualitative studies. Medline, Embase, Cinahl and PsycInfo were searched for relevant studies published in English and German between 1996 and 2011. Papers were included if they contained qualitative data, for example from interviews or focus groups, reporting the views of parents and caregivers of children with a range of long-term conditions on their treatment adherence. Papers were quality assessed and analysed using thematic synthesis.

Results

Nineteen papers were included reporting 17 studies with caregivers from 423 households in five countries. Long-term conditions included; asthma, cystic fibrosis, HIV, diabetes and juvenile arthritis. Across all conditions caregivers were making on-going attempts to balance competing concerns about the treatment (such as perceived effectiveness or fear of side effects) with the condition itself (for instance perceived long-term threat to child). Although the barriers to implementing treatment regimens varied across the different conditions (including complexity and time-consuming nature of treatments, un-palatability and side-effects of medications), it was clear that caregivers worked hard to overcome these day-to-day challenges and to deal with child resistance to treatments. Yet, carers reported that strict treatment adherence, which is expected by health professionals, could threaten their priorities around preserving family relationships and providing a ‘normal life’ for their child and any siblings.

Conclusions

Treatment adherence in long-term pediatric conditions is a complex issue which needs to be seen in the context of caregivers balancing the everyday needs of the child within everyday family life. Health professionals may be able to help caregivers respond positively to the challenge of treatment adherence for long-term conditions by simplifying treatment regimens to minimise impact on family life and being aware of difficulties around child resistance and supportive of strategies to attempt to overcome this. Caregivers would also welcome help with communicating with children about treatment goals.

Plasma lopinavir concentrations predict virological failure in a cohort of South African children initiating a protease-inhibitor-based regimen

BACKGROUND

Poor adherence to antiretroviral therapy contributes to pharmacokinetic variability and is the major determinant of virological failure. However, measuring treatment adherence is difficult, especially in children. We investigated the relationship between plasma lopinavir concentrations, pretreatment characteristics and viral load >400 copies/ml.

METHODS

A total of 237 HIV-infected children aged 4-42 months on lopinavir/ritonavir oral solution were studied prospectively and followed for up to 52 weeks. Viral load and lopinavir concentration were measured at clinic visits 12, 24, 36 and 52 weeks after starting treatment. Cox multiple failure events models were used to estimate the crude and adjusted effect of lopinavir concentrations on the hazard of viral load >400 copies/ml.

RESULTS

The median (IQR) pretreatment CD4(+) T-lymphocyte percentage was 18.80% (12.70-25.35) and 53% of children had a pretreatment viral load >750,000 copies/ml. The median (IQR) weight-for-age and height-for-age z-scores were -2.17 (-3.35--2.84) and -3.34 (-4.57--3.41), respectively. Median (IQR) lopinavir concentrations were 8.00 mg/l (4.11-12.42) at median (IQR) 3.50 h (2.67-4.25) after the dose. The hazard of viral load >400 copies/ml was increased with lopinavir concentrations <1 mg/l versus ≥1 mg/l (adjusted hazard ratio 2.3 [95% CI 1.63, 3.26]) and lower height-for-age z-scores.

CONCLUSIONS

Low lopinavir concentrations (<1 mg/l) are associated with viraemia in children. This measure could be used as a proxy for adherence and to determine which children are more likely to fail.

Smartphone medication adherence apps: potential benefits to patients and providers

OBJECTIVES

To provide an overview of medication adherence, discuss the potential for smartphone medication adherence applications (adherence apps) to improve medication nonadherence, evaluate features of adherence apps across operating systems (OSs), and identify future opportunities and barriers facing adherence apps.

PRACTICE DESCRIPTION

Medication nonadherence is a common, complex, and costly problem that contributes to poor treatment outcomes and consumes health care resources. Nonadherence is difficult to measure precisely, and interventions to mitigate it have been largely unsuccessful.

PRACTICE INNOVATION

Using smartphone adherence apps represents a novel approach to improving adherence. This readily available technology offers many features that can be designed to help patients and health care providers improve medication-taking behavior.

MAIN OUTCOME MEASURES

Currently available apps were identified from the three main smartphone OSs (Apple, Android, and Blackberry). In addition, desirable features for adherence apps were identified and ranked by perceived importance to user desirability using a three-point rating system: 1, modest; 2, moderate; or 3, high. The 10 highest-rated apps were installed and subjected to user testing to assess app attributes using a standard medication regimen. RESULTS 160 adherence apps were identified and ranked. These apps were most prevalent for the Android OS. Adherence apps with advanced functionality were more prevalent on the Apple iPhone OS. Among all apps, MyMedSchedule, MyMeds, and RxmindMe rated the highest because of their basic medication reminder features coupled with their enhanced levels of functionality.

CONCLUSION

Despite being untested, medication apps represent a possible strategy that pharmacists can recommend to nonadherent patients and incorporate into their practice.

Linkage, initiation and retention of children in the antiretroviral therapy cascade: an overview

In 2012, there were an estimated 2 million children in need of antiretroviral therapy (ART) in the world, but ART is still reaching fewer than 3 in 10 children in need of treatment. [1, 7] As more HIV-infected children are identi&filig;ed early and universal treatment is initiated in children under 5 regardless of CD4, the success of pediatric HIV programs will depend on our ability to link children into care and treatment programs, and retain them in those services over time. In this review, we summarize key individual, institutional, and systems barriers to diagnosing children with HIV, linking them to care and treatment, and reducing loss to follow-up (LTFU). We also explore how linkage and retention can be optimally measured so as to maximize the impact of available pediatric HIV care and treatment services.

Self-reported adherence to medications in a pediatric renal clinic: psychological aspects

Background

Chronically ill children and adolescents comprise a vulnerable population that requires specific considerations in order to positively impact their treatment outcome. Pediatric renal patients can be non-compliant and also forgetful in taking their medications.

Objective

The objectives of the study were to (a) assess medication adherence and (b) to identify emotionality and variables that influence non-adherence by use of “The Child & Adolescent Adherence to Medication Questionnaire” (CAAMQ), which was constructed at Texas Tech University Health Sciences Center.

Methods

Pediatric renal patients from 10 to 21 years-of-age, taking three or more medications, for longer than a three-month period, were eligible to complete the CAAMQ.

Results

Thirty-four patients participated in the study. Many of the respondents had problems remembering to take their medications on weekends (P = 0.021). The majority of the patients stated that they were not bothered about having to take their medications (70.6%); and that taking pills did not interfere with their daily activities (85.3%). Open-ended questions in the CAAMQ identified patients’ feelings of sadness, distress, and the importance of strong family support systems. The study participants reported that they preferred to take their medications at school, in the nurses’ office or in a place where privacy was assured. The results indicated that Prednisone was the most disliked of all of the medications. Female patients were more reactive and secretive than males regarding peers knowing about their disease and medication schedules (P<0.017).

Conclusions

Non-adherence in pediatric patients is a complex and serious problem, which ultimately affects the patients’ health. Privacy and daily routine were found to impact the patients’ adherence to medications. Creative and individualized reminders for teenagers need to be developed and validated. Further studies that take into consideration developmental and motivational factors may help researchers identify modifiable psychosocial predictors that will lead to improved medication adherence.

Preventing HIV among young people: research priorities for the future

OBJECTIVE

To review the current state of knowledge on the prevention of sexual transmission of HIV in adolescents and to highlight the existing gaps and priority areas for future research.

BACKGROUND

A disproportionate burden of HIV infections falls on adolescents, a developmental stage marked by unique neural, biological, and social transition. Successful interventions are critical to prevent the spread of HIV in this vulnerable population.

METHODS

We summarized the current state of research on HIV prevention in adolescents by providing examples of successful interventions and best practices, and highlighting current research gaps.

RESULTS

Adolescent interventions fall into 3 main categories: biomedical, behavioral, and structural. The majority of current research has focused on individual behavior change, whereas promising biomedical and structural interventions have been largely understudied in adolescents. Combination prevention interventions may be particularly valuable to this group.

CONCLUSIONS

Adolescents have unique needs with respect to HIV prevention, and, thus, interventions should be designed to most effectively reach out to this population with information and services that will be relevant to them.

Managed problem solving for antiretroviral therapy adherence: a randomized trial

BACKGROUND

Adherence to antiretroviral therapy is critical to successful treatment of human immunodeficiency virus (HIV). Few interventions have been demonstrated to improve both adherence and virologic outcomes. We sought to determine whether an intervention derived from problem solving theory, Managed Problem Solving (MAPS), would improve antiretroviral outcomes.

METHODS

We conducted a randomized investigator blind trial of MAPS compared with usual care in HIV-1 infected individuals at 3 HIV clinics in Philadelphia, Pennsylvania. Eligible patients had plasma HIV-1 viral loads greater than 1000 copies/mL and were initiating or changing therapy. Managed Problem Solving consists of 4 in-person and 12 telephone-based meetings with a trained interventionist, then monthly follow-up calls for a year. Primary outcome was medication adherence measured using electronic monitors, summarized as fraction of doses taken quarterly over 1 year. Secondary outcome was undetectable HIV viral load over 1 year. We assessed 218 for eligibility, with 190 eligible and 180 enrolled, 91 randomized to MAPS and 89 to usual care. Fifty-six participants were lost to follow-up: 33 in the MAPS group and 23 in usual care group.

RESULTS

In primary intention-to-treat analyses, the odds of being in a higher adherence category was 1.78 (95% CI,1.07-2.96) times greater for MAPS than usual care. In secondary analyses, the odds of an undetectable viral load was 1.48 (95% CI, 0.94-2.31) times greater for MAPS than usual care. In as-treated analyses, the effect of MAPS was stronger for both outcomes. There was neither a difference by prior treatment status nor change in effect over time.

CONCLUSIONS

Managed Problem Solving is an effective antiretroviral adherence intervention over the first year with a new regimen. It was equally effective at improving adherence in treatment experienced and naïve patients and did not lose effect over time. Implementation of MAPS should be strongly considered where resources are available.
