Barriers to antiretroviral adherence for patients living with HIV infection and AIDS in Botswana

Spinning plates: livelihood mobility, household responsibility and anti-retroviral treatment in an urban Zambian community during the HPTN 071 (PopART) study

INTRODUCTION

Qualitative data are lacking on the impact of mobility among people living with HIV (PLHIV) and their decision-making around anti-retroviral treatment (ART). We describe challenges of juggling household responsibility, livelihood mobility and HIV management for six PLHIV in urban Zambia.

METHODS

Six PLHIV (three men and three women, aged 21 to 44) were recruited from different geographic zones in one urban community drawn from a qualitative cohort in a social science component of a cluster-randomized trial (HPTN071 PopART). Participants were on ART (n = 2), not on ART (n = 2) and had started and stopped ART (n = 2). At least two in-depth interviews and participant observations, and three drop-in household visits with each were carried out between February and August 2017. Themed and comparative analysis was conducted.

RESULTS

The six participants relied on the informal economy to meet basic household needs. Routine livelihood mobility, either within the community and to a nearby town centre, or further afield for longer periods of time, was essential to get by. Although aware of ART benefits, only one of the six participants managed to successfully access and sustain treatment. The other five struggled to find time to access ART alongside other priorities, routine mobility and when daily routines were more chaotic. Difficulty in accessing ART was exacerbated by local health facility factors (congestion, a culture of reprimanding PLHIV who miss appointments, sporadic rationed drug supply), stigma and more limited social capital.

CONCLUSIONS

Using a time-space framework illustrated how household responsibility, livelihood mobility and HIV management every day were like spinning plates, each liable to topple and demanding constant attention. If universal lifelong ART is to be delivered, the current service model needs to adjust the limited time that some PLHIV have to access ART because of household responsibilities and the need to earn a living moving around, often away from home. Practical strategies that could facilitate ART access in the context of livelihood mobility include challenging the practice of reprimand, improving drug supply, having ART services more widely distributed, mapped and available at night and weekends, and an effective centralized client health information system.

Mood, cognitive structuring and medication adherence

A study with a placebo was conducted. Healthy university students were given a placebo and were told to make one pill every day for a week. Participants were informed that the medicine improved mood. The extent to which they conformed to this instruction was treated as an index of compliance. Our results show that for women, but not for men, positive mood and cognitive structuring or negative mood and lack of cognitive structuring significantly predicted participants' compliance. A new model of medication adherence, based on the role of the patient's mood and cognitive structuring processes in decision making is presented in the paper.

Multivariate analysis of covariates of adherence among HIV-positive mothers with low viral suppression

Background

As part of efforts to improve the prevention of mother-to-child transmission in Northern Uganda, we explored reasons for poor viral suppression among 122 pregnant and lactating women who were in care, received viral load tests, but had not achieved viral suppression and had more than 1000 copies/mL. Understanding the patient factors associated with low viral suppression was of interest to the Ministry of Health to guide the development of tools and interventions to achieve viral suppression for pregnant and lactating women newly initiating on ART as well as those on ART with unsuppressed viral load.

Methods

A facility-based cross-sectional and mixed methods study design was used, with retrospective medical record review. We assessed 122 HIV-positive mothers with known low viral suppression across 31 health facilities in Northern Uganda. Adjusted odds ratios were used to determine the covariates of adherence among HIV positive mothers using logistic regression. A study among health care providers shed further light on predictors of low viral suppression and a history of low early retention. This study was part of a larger national evaluation of the performance of integrated care services for mothers.

Results

Adherence defined as taking antiretroviral medications correctly everyday was low at 67.2%. The covariates of low adherence are: taking other medications in addition to ART, missed appointments in the past 6 months, experienced violence in the past 6 months, and faces obstacles to treatment. Mothers who were experiencing each of these covariates were less likely to adhere to treatment. These covariates were triangulated with perspectives of health providers as covariates of low adherence and included: long distances to health facility, missed appointments, running out of pills, sharing antiretroviral drugs, violence, and social lifestyles such as multiple sexual partners coupled with non-disclosure to partners. Inadequate counseling, stigma, and lack of client identity are the frontline factors accounting for the early loss of mothers from care.

Conclusions

Adherence of 67% was low for reliable viral suppression and accounts for the low viral suppression among HIV-positive mothers studied, in absence of any other factors. This study provided insights into the covariates for low adherence to ART and low viral load suppression; these covariates included taking other medications in addition to ART, missed appointments in the past 6 months, feels like giving up, doesn’t have someone with whom to share private concerns, experienced violence in the past 6 months, and faces obstacles to treatment and confirmed by health providers. To improve adherence, we recommend use of a screening tool to identify mothers with any of these covariates so that more intensive adherence support can be provided to these mothers.

Adherence to antiretroviral therapy and factors affecting low medication adherence among incident HIV-infected individuals during 2009-2016: A nationwide study

For ideal clinical benefit, human immunodeficiency virus (HIV)-infected individuals should receive continuous medication. This is the first nationwide antiretroviral therapy (ART) adherence study in Asia, where medication monitoring at national level is systemically available. We estimated the ART adherence of incident HIV-infected individuals and investigated factors affecting low medication adherence using the national health insurance (NHI) claims data from 2007 to 2016. Medication possession ratio (MPR) was used to measure medication adherence and risk factors were identified by multivariable logistic regression analysis. Of the 8,501 newly diagnosed HIV-infected individuals during 2009–2016 with at least one ART prescription, 70.4% of HIV patients had adequate adherence to ART defined as MPR ≥95%. Requiring prophylactic antibiotics, female gender, age of 0–19 and same or over 50 s compared to 30–39, and having a history of malignancy, lower socioeconomic status, not visiting tertiary hospital, and being diagnosed in the earlier years were risk factors for lower adherence (Odds ratio 1.7, 1.6, 1.6, 1.4, 1.6, 2.1, 1.2, and 1.6 to 3.8 respectively). Health authority should take into consideration of these modifiable and unmodifiable barriers to establish sustainable monitoring system at national level and to improve adherence.

Barriers to HIV Medication Adherence as a Function of Regimen Simplification

BACKGROUND

Barriers to HIV medication adherence may differ by levels of dosing schedules.

PURPOSE

The current study examined adherence barriers associated with medication regimen complexity and simplification.

METHODS

A total of 755 people living with HIV currently taking anti-retroviral therapy were recruited from community services in Atlanta, Georgia. Participants completed audio-computer-assisted self-interviews that assessed demographic and behavioral characteristics, provided their HIV viral load obtained from their health care provider, and completed unannounced phone-based pill counts to monitor medication adherence over 1 month.

RESULTS

Participants taking a single-tablet regimen (STR) were more likely to be adherent than those taking multi-tablets in a single-dose regimen (single-dose MTR) and those taking multi-tablets in a multi-dose regimen (multi-dose MTR), with no difference between the latter two. Regarding barriers to adherence, individuals taking STR were least likely to report scheduling issues and confusion as reasons for missing doses, but they were equally likely to report multiple lifestyle and logistical barriers to adherence.

CONCLUSIONS

Adherence interventions may need tailoring to address barriers that are specific to dosing regimens.

Community-Based Accompaniment and the Impact of Distance for HIV Patients Newly Initiated on Antiretroviral Therapy: Early Outcomes and Clinic Visit Adherence in Rural Rwanda

Community-based accompaniment (CBA) has been associated with improved antiretroviral therapy (ART) patient outcomes in Rwanda. In contrast, distance has generally been associated with poor outcomes. However, impact of distance on outcomes under the CBA model is unknown. This retrospective cohort study included 537 adults initiated on ART in 2012 in two rural districts in Rwanda. The primary outcomes at 6 months after ART initiation included overall program status, missed a visit and missed three consecutive visits. The associations between cost surface distance (straight-line distance adjusted for surface features) and outcomes were assessed using logistic regression, controlling for potential confounders. Died/lost-to-follow-up and missed three consecutive visits were not associated with distance. Patients within 0-1 km cost surface distance were significantly more likely to miss a visit, potentially due to stigma of attending clinic within one's community. These results suggest that CBA may mediate the impact of long distances on outcomes.

A systematic review of psychological correlates of HIV testing intention

Undiagnosed HIV infection is associated with onward HIV transmission and delays in accessing HIV care and treatment. As a significant proportion of HIV tests are self-initiated, it is important to assess correlates of the intention to test for HIV. Psychological correlates of HIV testing intention are more likely to be the feasible target of interventions than structural determinants. A systematic review of psychological correlates of HIV testing intention was conducted. Twenty studies were included in the review, covering a range of populations and geographical regions. The most commonly assessed variables were HIV risk perception and HIV knowledge rather than HIV test-specific psychological factors. There was evidence that HIV risk perception and pro-testing attitudes were consistently associated with HIV testing intention across a number of studies. There is a need for longitudinal designs, including experimental studies, allowing for more confident casual inferences to be made. Theoretical, research and practice implications are outlined.

Proximity to healthcare clinic and depression risk in South Africa: geospatial evidence from a nationally representative longitudinal study

Proximity to primary healthcare facilities may be a serious barrier to accessing mental health services in resource-limited settings. In this study, we examined whether the distance to the primary healthcare clinic (PHCC) was associated with risk of depression in KwaZulu-Natal Province, South Africa. Depressive symptoms and household coordinates data were accessed from the nationally representative South African National Income Dynamics Study. Distances between households and their nearest PHCCs were calculated and mixed-effects logistic regression models fitted to the data. Participants residing <6 km from a PHCC (aOR = 0.608, 95% CI 0.42-0.87) or 6-14.9 km (aOR = 0. 612, 95% CI 0.44-0.86) had a lower depression risk compared to those residing ≥15 km from the nearest PHCC. Distance to the PHCC was independently associated with increased depression risk, even after controlling for key socioeconomic determinants. Minimizing the distance to PHCC through mobile health clinics and technology could improve mental health.

The relationship between negative responses to HIV status disclosure and psychosocial outcomes among people living with HIV

This report examines rates of HIV status disclosure and negative responses to disclosure among people living with HIV in Australia. Among 697 people living with HIV, most (>90%) had disclosed their status to friends, sexual partners and health providers. Almost a third had not disclosed to family, and half had not told any work colleagues. Negative responses to disclosure (e.g. blame, rejection) by all groups were associated with increased HIV-related stigma, psychological distress and diminished social support and health satisfaction. These results shed light on rates of disclosure among people living with HIV in Australia and the adverse health impacts of negative responses to disclosure.

Optimal antiretroviral therapy adherence as evaluated by CASE index score tool is associated with virological suppression in HIV-infected adults in Dakar, Senegal

OBJECTIVE

To determine the prevalence and factors associated with optimal antiretroviral therapy (ART) adherence and virological failure (VLF) among HIV-infected adults enrolled in the national ART programme at the teaching hospital of Fann, Dakar, Senegal.

METHODS

Cross-sectional study from 1 September 2013 to 30 January 2014.

OUTCOMES

(1) optimal ART adherence by the Center for Adherence Support Evaluation (CASE) Index Score (>10) and (2) VLF (HIV RNA > 1000 copies/ml). Diagnostic accuracy of CASE Index Score assessed using sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV) and corresponding 95% confidence intervals (CIs). Multivariate logistic regression analysis was performed to identify independent factors associated with optimal adherence and VLF.

RESULTS

Of 98 HIV-infected patients on ART, 68% were female. The median (IQR) age was 42 (20-50) years. A total of 57 of 98 (60%) were on ART more than 3 years, and majority (88%) were on NNRTI-based first-line ART regimen. A total of 79 of 98 (80%) patients reported optimal ART adherence, and only five of 84 (5.9%) had documented VLF. Patients with VLF were significantly more likely to have suboptimal ART adherence (17.7% vs. 2.9%; P = 0.02). CASE Index Score showed the best trade-off in Se (78.9%, 95% CI: 54.4-93.9%), Sp (20.0%, 95% CI: 11.1-31.7), PPV (22.4, 95% CI: 13.1-34.2%) and NPV (76.5%, 95% CI: 50.1-93.2), when used VLF threshold of HIV RNA >50 copies/ml. Factors independently associated with VLF were CASE Index Score <10 ([aOR] = 13.0, 95% CI: 1.1-147.9; P = 0.04) and being a boosted PI-based ART regimen ([aOR] = 27.0, 95% CI: 2.4-309.4; P = 0.008).

CONCLUSIONS

Optimal ART adherence is achievable in a high proportion of HIV-infected adults in this study population. CASE Index Score was independently associated with virological outcomes, supporting usefulness of this low-cost ART adherence monitoring tool in this setting.

A Multilevel Conceptual Framework to Understand the Role of Food Insecurity on Antiretroviral Therapy Adherence in Low-Resource Settings: From Theory to Practice

The objective of this study was to describe a multilevel conceptual framework to understand the role of food insecurity on antiretroviral therapy adherence. The authors illustrated an example of how they used the multilevel framework to develop an intervention for poor people living with HIV in a rural and low-resource community. The framework incorporates intrapersonal, interpersonal, and structural-level theories of understanding and changing health behaviors. The framework recognizes the role of personal, social, and environmental factors on cognition and behavior, with particular attention to ways in which treatment adherence is enabled or prevented by structural conditions, such as food insecurity.

Treatment Outcomes Among Older Human Immunodeficiency Virus-Infected Adults in Nigeria

Background

Older age at initiation of combination antiretroviral therapy (cART) has been associated with poorer clinical outcomes. Our objectives were to compare outcomes between older and younger patients in our clinical cohort in Jos, Nigeria.

Methods

This retrospective cohort study evaluated patients enrolled on cART at the Jos University Teaching Hospital, Nigeria between 2004 and 2012. We compared baseline and treatment differences between older (≥50 years) and younger (15–49 years) patients. Kaplan-Meier analysis and Cox proportional hazard models estimated survival and loss to follow-up (LTFU) and determined factors associated with these outcomes at 24 months.

Results

Of 8352 patients, 643 (7.7%) were aged ≥50 years. The median change in CD4 count from baseline was 151 vs 132 (P = .0005) at 12 months and 185 vs 151 cells/mm³ (P = .03) at 24 months for younger and older patients, respectively. A total of 68.9% vs 71.6% (P = .13) and 69.6% vs 74.8% (P = .005) of younger and older patients achieved viral suppression at 12 and 24 months, with similar incidence of mortality and LTFU. In adjusted hazard models, factors associated with increased risk of mortality were male sex, World Health Organization (WHO) stage III/IV, and having a gap in care, whereas being fully suppressed was protective. The risk of being LTFU was lower for older patients, those fully suppressed virologically and with adherence rates >95%. Male sex, lack of education, WHO stage III/IV, body mass index <18.5 kg/m², and having a gap in care independently predicted LTFU.

Conclusions

Older patients achieved better viral suppression, and older age was not associated with increased mortality or LTFU in this study.

From HIV diagnosis to initiation of treatment: Social transformation among people starting antiretroviral therapy in Peru

Social support is a key, yet elusive resource for HIV patients living in poverty in Lima, Peru. Despite a greater need for health services and encouragement from others, economic restraints, stigma, and trouble negotiating a fractured health system act as hurdles to accessing support. In this study, 33 people with HIV and 15 of their treatment supporters were interviewed upon initiation of antiretroviral therapy in order to understand changes in social support during this critical time, and how these changes affected their well-being. Everyone's social network underwent dramatic transformation, while some were rejected upon disclosure by people they knew, many successfully trimmed their social circles to a few trusted parties. Treatment supporters were most frequently the first to whom they disclosed their HIV status, and most backed the person with HIV, although sometimes out of obligation. HIV peers became a vital new source of strength. Ultimately, people with HIV who successfully reorganized their social network drew personal strength and self-worth from new and old relationships in their lives.

Determinants of adherence to antiretroviral therapy among HIV-positive adults in sub-Saharan Africa: a systematic review

OBJECTIVE

The rapid scale up of antiretroviral treatment (ART) in sub-Saharan Africa (SSA) has resulted in an increased focus on patient adherence. Non-adherence can lead to drug-resistant HIV caused by failure to achieve maximal viral suppression. Optimal treatment requires the identification of patients at high risk of suboptimal adherence and targeted interventions. The aim of this review was to identify and summarise determinants of adherence to ART among HIV-positive adults.

DESIGN

Systematic review of adherence to ART in SSA from January 2002 to October 2014.

METHODS

A systematic search was performed in 6 databases (PubMed, Cochrane Library, EMBASE, Web of Science, Popline, Global Health Library) for qualitative and quantitative articles. Risk of bias was assessed. A meta-analysis was conducted for pooled estimates of effect size on adherence determinants.

RESULTS

Of the 4052 articles screened, 146 were included for final analysis, reporting on determinants of 161 922 HIV patients with an average adherence score of 72.9%. Main determinants of non-adherence were use of alcohol, male gender, use of traditional/herbal medicine, dissatisfaction with healthcare facility and healthcare workers, depression, discrimination and stigmatisation, and poor social support. Promoters of adherence included counselling and education interventions, memory aids, and active disclosure among people living with HIV. Determinants of health status had conflicting influence on adherence.

CONCLUSIONS

The sociodemographic, psychosocial, health status, treatment-related and intervention-related determinants are interlinked and contribute to optimal adherence. Clinics providing ART in SSA should therefore design targeted interventions addressing these determinants to optimise health outcomes.

Intimate partner violence and challenges facing women living with HIV/AIDS in accessing antiretroviral treatment at Singida Regional Hospital, central Tanzania

BACKGROUND

Human immunodeficiency virus (HIV) remains a global public health problem. Sub-Saharan Africa is the region most affected by HIV/AIDS in the world. Globally, and in Tanzania in particular, women are more affected by HIV/AIDS than men. Tanzania has been reported to be among the countries with the highest burden of intimate partner violence (IPV). This study explored the challenges facing women living with HIV/AIDS (LWHA) attending the care and treatment clinic (CTC) in Singida Regional Hospital in Tanzania.

DESIGN

A qualitative study was performed in which data were collected through in-depth interviews with 35 women LWHA who also experienced IPV. Content analysis was used to analyse the data.

RESULTS

The study findings showed that women LWHA experienced challenges from their male partners in the form of lack of fare to attend CTC, delayed attendance to CTC, verbal threats and intimidation, mistrust partner resulting in changed antiretroviral (ARV) dosing time. Also, systemic challenges such as malfunction of CD4 count testing apparatus contributed to mistrust from their male partners which led to IPV.

CONCLUSION

In this study, women LWHA experienced IPV challenges that resulted in poor adherence to ARV medication and CTC attendance, as well as insufficient time to collect ARV medication. It is recommended that the government address systemic challenges faced by women LWHA, introduce multiple approaches to address the needs of women LWHA experiencing IPV, and develop strong policies to prevent IPV against women in Tanzania, regardless of their HIV status.

High levels of retention in care with streamlined care and universal test and treat in East Africa

OBJECTIVE

We sought to measure retention in care and identify predictors of nonretention among patients receiving antiretroviral therapy (ART) with streamlined delivery during the first year of the ongoing Sustainable East Africa Research on Community Health (SEARCH) 'test-and-treat' trial (NCT 01864603) in rural Uganda and Kenya.

DESIGN

Prospective cohort of patients in the intervention arm of the SEARCH study.

METHODS

We measured retention in care at 12 months among HIV-infected adults who linked to care and were offered ART regardless of CD4 cell count, following community-wide HIV-testing. Kaplan-Meier estimates and Cox proportional hazards modeling were used to calculate the probability of retention at 1 year and identify predictors of nonretention.

RESULTS

Among 5683 adults (age ≥15) who linked to care, 95.5% [95% confidence interval (CI): 92.9-98.1%] were retained in care at 12 months. The overall probability of retention at 1 year was 89.3% (95% CI: 87.6-90.7%) among patients newly linking to care and 96.4% (95% CI: 95.8-97.0%) among patients previously in care. Younger age and pre-ART CD4 cell count below country treatment initiation guidelines were predictors of nonretention among all patients. Among those newly linking, taking more than 30 days to link to care after HIV diagnosis was additionally associated with nonretention at 1 year. HIV viral load suppression at 12 months was observed in 4227 of 4736 (89%) of patients retained with valid viral load results.

CONCLUSION

High retention in care and viral suppression after 1 year were achieved in a streamlined HIV care delivery system in the context of a universal test-and-treat intervention.

Medication Adherence in 13- to 24-Year-Old Youth Living With HIV

Despite advances in HIV medicine, adherence presents as a barrier to effective treatment for youth. We designed this study to assess medication knowledge, adherence, and factors affecting adherence in youth with HIV. Participants were 72 youth ages 13 to 24 years with perinatally or behaviorally acquired HIV. Demographic data were collected and a self-report adherence interview was administered. Interviews were audio-recorded to allow for qualitative data analysis. Self-reported adherence varied depending on the framing of questions, with participants reporting greater adherence when asked how many doses they had missed within the past 7 days compared to results from a 7-day recall interview. At least 74% of the sample said they sometimes forgot to take their medication. A taxonomic approach to the qualitative analysis revealed internal and external facilitators and barriers to adherence. Findings suggest a need for education and provider support to include strategies to improve adherence.

Adherence to antiretroviral therapy among HIV and AIDS patients at the Kwa-Thema clinic in Gauteng Province, South Africa

Background

Introduction of antiretroviral therapy (ART) has shown reduction in HIV-related mortality and morbidity in people living with HIV and AIDS. Since high levels of adherence of more than 95.0% is required to achieve effective suppression of viral load, researchers found it important to establish whether people are pursuing what is expected of them.

Aim and setting

The study was aimed at determining adherence to ART among HIV and AIDS patients at the Kwa-Thema clinic in Gauteng Province

Methods

Quantitative cross-sectional descriptive design was used. Ethical clearance was sort from MEDUNSA Research Ethics Committee. Validity and reliability were maintained throughout the study. A non-probability systematic sampling was used. Data were collected using administered structured questionnaire, and a total of 290 respondents were involved. Data were analysed using SPSS software version 22.

Results

The findings indicated that the adherence to ART was 77.0%. Factors that were significantly associated with adherence were gender (χ² = 3.78, df = 1, p < 0.05), level of education (χ² = 3.52, df = 3, p = 0.032), co-treatment of HIV and other infections (χ² = 5.46, df = 4, p = 0.019), ability to follow ART (χ² = 12.82, df = 1, p = 0.000 < 0.05), and types of antiretroviral drugs.

Recommendation

The study recommends intensification of health education campaign against stigma and gender discrimination. Providing feedback to patients regarding benefits of ART is important.

Conclusion

The study concluded that adherence to ART at the Kwa-Thema clinic was sub-optimal (less than 95%) at 77%, but comparable with the adherence levels in other developing countries.

Effect of 2 Models of Care and Factors Predicting Patients' Adherence to Doctor's Appointment Attendance in Lagos State University Teaching Hospital, Ikeja, Lagos, Nigeria

BACKGROUND

Provision of antiretroviral therapy in resource limited settings has put pressure on the available infrastructure.

OBJECTIVES

The study examined patients' adherence to Doctor's appointment attendance after an intervention changing the model of care and factors that predicted adherence.

METHODS

Observational study was carried out over four years. The model of care was changed in the last year and the effect assessed. SPSS version 15.0 was used for analysis. Predictors of adherence were determined using logistic regression model.

RESULTS

Over half 148 (59.7%) of the patients were females, with a mean age of 40.4±8.8 years and baseline CD4 cells of 143.5±92.7cells/microliters. "Adherence" rates were 51.3% in 2007, 35.9% in 2008 and 14.9% in 2009 giving patients' average adherence to Doctor's appointment attendance of 34.03%. Intervention changing the model of care in 2010 recorded an adherence rate of 93.1%.

CONCLUSIONS

The change in model of care greatly improved patients' "adherence". Patients' knowledge of management, adherence, and smoking and drinking habits were identified as statistically significant predictors of adherence.

Factors Associated with Prevalent Tuberculosis Among Patients Receiving Highly Active Antiretroviral Therapy in a Nigerian Tertiary Hospital

Background:

Tuberculosis (TB) causes significant morbidity/mortality among human immunodeficiency virus-infected individuals in Africa. Reducing TB burden in the era of highly active antiretroviral therapy (HAART) is a public health priority.

Aim:

We determined the factors associated with prevalent TB among patients receiving HAART.

Subjects and Methods:

We conducted a cross-sectional study of adult patients who had received HAART for ≥12 weeks in a Nigerian tertiary hospital. Patients whose TB diagnosis predated HAART were excluded from the study. Pre-HAART data were collected from the clinic records, whereas post-HAART data were obtained through medical history, physical examination, and laboratory investigations. Standard TB screening/diagnostic algorithms as applicable in Nigeria were used. Logistic regression analysis was used to determine factors independently associated with prevalent TB.

Results:

about 65.8% (222/339) were women. The mean age was 41.1 (10.0) years and 23.6% (73/339) had past history of TB. The prevalence of active TB was 7.7% (26/339). Among these patients, 42.3% (11/26) had pulmonary TB, 34.6% (9/26) had disseminated TB, whereas 23.1% (6/26) had only extra-pulmonary disease. Only 45% (9/20) of patients with pulmonary involvement had positive sputum smear. Factors independently associated with prevalent TB were lower social class (adjusted odds ratio [aOR]: 31.7; 95% confidence interval [CI]: 1.1–1417.3), HAART non-adherence (aOR125.5; 95% CI: 9.6–1636.3), baseline CD4 <200cells/μl (aOR31.0; 95%CI: 1.6–590.6), previous TB (aOR13.8; 95% CI: 2.0–94.1), and current hemoglobin <10 g/dl (aOR10.3; 95% CI: 1.1–99.2).

Conclusion:

Factors associated with prevalent TB were a lower social class, HAART non-adherence, severe immunosuppression before HAART initiation, previous TB, and anemia post-HAART. TB case finding should be intensified in these high-risk groups.

Community-Based Accompaniment Mitigates Predictors of Negative Outcomes for Adults on Antiretroviral Therapy in Rural Rwanda

Clinical, socioeconomic, and access barriers remain a critical problem to antiretroviral (ART) programs in sub-Saharan Africa. Community-based accompaniment (CBA), including daily home visits and psychosocial and socioeconomic support, has been associated with improved patient outcomes at 1 year. We conducted a prospective observational cohort study of 578 HIV-infected adults initiating ART in 2007-2008 with or without CBA in rural Rwanda. Among patients without CBA, those with advanced HIV disease, low CD4 cell counts, lower social support, and transport costs had significantly higher odds of negative outcomes at 1 year; amongst patients who received CBA, only those with low CD4 cell counts had significantly higher odds of negative outcomes at 1 year. CBA also significantly mitigated the effect of transport costs and inaccessibility of services on the likelihood of negative outcome. CBA may be one approach to mitigating known risk factors for negative outcomes for patients on ART in resource-poor settings.

Relationship between characteristics of volunteer community health workers and antiretroviral treatment outcomes in a community-based treatment programme in Uganda

Community health workers (CHWs) can help to redress the shortages of health human resources needed to scale up antiretroviral treatment (ART). However, the selection of CHWs could influence the effectiveness of a CHW programme. The purpose of this observational study was to assess whether sociodemographic characteristics and geographic proximity to patients of volunteer CHWs were predictors of clinical outcomes in a community-based ART (CBART) programme in Kabarole, Uganda. Data from CHW surveys for 41 CHWs and clinic charts for 185 patients in the CBART programme were analysed using multivariable logistic and Cox regression models. Time to travel to patients was the only statistically significant characteristic of CHWs associated with ART outcomes. Patients whose CHWs had to travel one or more hours had a 71% lower odds of virologic suppression (adjusted OR = 0.29, 95% CI = 0.13-0.65, p = .002) and a 4.52 times higher mortality hazard rate (adjusted HR = 4.52, 95% CI = 1.20-17.09, p = .026) compared to patients whose CHWs had to travel less than one hour. The findings show that the sociodemographic characteristics of CHWs were not as important as the geographic distance they had to travel to patients.

Adherence to antiretroviral therapy and its determinants among persons living with HIV/AIDS in Bayelsa state, Nigeria

Background:

A high level of adherence is required to achieve the desired outcomes of antiretroviral therapy. There is paucity of information about adherence to combined antiretroviral therapy in Bayelsa State of southern Nigeria.

Objectives:

The objectives of the study were to determine the level of adherence to combined antiretroviral therapy among the patients, evaluate the improvement in their immune status and identify reasons for sub-optimal adherence to therapy.

Methods:

The cross-sectional study involved administration of an adapted and pretested questionnaire to 601 consented patients attending the two tertiary health institutions in Bayesla State,

Nigeria:

The Federal Medical Centre, Yenagoa and the Niger-Delta University Teaching Hospital Okolobiri. The tool was divided into various sections such as socio-demographic data, HIV knowledge and adherence to combined antiretroviral therapy. Information on the patient’s CD4+ T cells count was retrieved from their medical records. Adherence was assessed by asking patients to recall their intake of prescribed doses in the last fourteen days and subjects who had 95-100% of the prescribed antiretroviral drugs were considered adherent.

Results:

Three hundred and forty eight (57.9%) of the subjects were females and 253 (42.1%) were males. The majority of them, 557 (92.7%) have good knowledge of HIV and combined anti-retroviral therapy with a score of 70.0% and above. A larger proportion of the respondents, 441 (73.4%), had ≥95% adherence. Some of the most important reasons giving for missing doses include, “simply forgot” 147 (24.5%), and “wanted to avoid the side-effects of drugs” 33(5.5%). There were remarkable improvements in the immune status of the subjects with an increment in the proportion of the subjects with CD4+ T cells count of greater than 350 cells/mm3 from 33 (5.5%) at therapy initiation to 338 (56.3%) at study period (p<0.0001).

Conclusion:

The adherence level of 73.4% was low which calls for intervention and improvement. The combined antiretroviral therapy has significantly improved the immune status of the majority of patients which must be sustained. “Simply forgot” was the most important reason for missing doses.

Social, Psychological and Health Concerns of People Living with HIV/AIDS in Mysore District, Karnataka

INTRODUCTION

One of the significant health and social problem the world facing today is Acquired immune deficiency syndrome (AiDS). The patients affected with HIV and their family may face various psychosocial problems during diagnosis and treatment due to the stigma associated with this disease.

AIM

The objective of the study was to identify social, psychological and health concerns of people living with HIV/AIDS (PLWHA) and its association with the demographic factors in Mysore District, Karnataka, India.

MATERIALS AND METHODS

A questionnaire based study was conducted among 194 participants in Mysore District, Karnataka state who were receiving care and support services. A 22-item questionnaire provided information regarding social, psychological and health concerns of PLWHA in Mysore district. A general linear regression model was used for assessing the predictors of social, psychological and health concerns.

RESULTS

The main social concern was that of "Fear of Losing a loved one" whereas the main psychological concern was "Too much worry", "No cure for AIDS" was the highly rated health concern. Males had more social, psychological and health concerns when compared to females but was not statistically significant. Employed people were having fewer psychological concerns when compared to unemployed people. Unemployed people were having fewer health concerns than employed people. For every unit increase in age there were fewer social and health concerns and both these findings were statistically significant.

CONCLUSION

PLWHA in the present study reported that they were concerned about social, psychological and health issues in spite of the fact they were attending counseling. Health care workers, including those in public health sector should be educated about the importance of these factors that influence the health of the population they are caring for.

Adherence to Antiretroviral Therapy and Its Determinants Among HIV-Infected Patients in Nigeria

PURPOSE

The study investigated the level of adherence and factors affecting adherence to antiretroviral treatment (ART).

METHODS

The study sample consisted of 300 HIV-infected patients who received ART in the Antiretroviral Clinic of Central Hospital, Agbor, Delta State, Nigeria. Self-reported adherence to ART in the previous 1 month prior to the study as well as determinants of adherence were assessed using a questionnaire.

RESULTS

The most frequently used ART regimen was zidovudine + lamivudine + nevirapine. On the whole, a total of 33 (11%) respondents missed 3 doses or less in the previous month prior to the survey. There was a statistically significant association between adherence to ART and marital status, source of income, and occupation ( P < .05). The most commonly reported reasons for missed doses were forgetfulness (60.4%), busy daily task (18.3%), and avoiding being seen while taking medications (11%).

CONCLUSION

The prevalence of adherence among the participants was high. However, more serious efforts are needed to reduce the number of in-adherent patients. Interventions to improve adherence to ART should address challenges such as forgetfulness among the patients and frequent occurrence of adverse effects and consider specific patient-related factors such as daily tasks.

The effect of altruism on the spending behavior of elderly caregivers of family members with HIV/AIDS in South African townships

HIV/AIDS has led to an enormous demand for health care in the developing world and many governments have opted to capitalize on altruistic home-based caregivers. These caregivers are mainly poor older women and their financial survival is critically important to themselves and their families. We found that as the patient's illness progressed: (a) the altruistic cultural norm "ubuntu" led the caregiver to increase spending and (b) the social pressure (sanction) of stigma led to a very dramatic drop in direct interpersonal assistance. The impact on their spending, health care, and the related public policies are discussed.

A socio-ecological perspective of access to and acceptability of HIV/AIDS treatment and care services: a qualitative case study research

Background

Access to healthcare is an essential element of health development and a fundamental human right. While access to and acceptability of healthcare are complex concepts that interact with different socio-ecological factors (individual, community, institutional and policy), it is not known how these factors affect HIV care. This study investigated the impact of socio-ecological factors on access to and acceptability of HIV/AIDS treatment and care services (HATCS) in Wolaita Zone of Ethiopia.

Method

Qualitative case study research was conducted in six woredas (districts). Focus group discussions (FGDs) were conducted with 68 participants in 11 groups (six with people using antiretroviral therapy (ART) and five with general community members). Key informant interviews (KIIs) were conducted with 28 people involved in HIV care, support services and health administration at different levels. Individual in-depth interviews (IDIs) were conducted with eight traditional healers and seven defaulters from (ART). NVIVO 10 was used to assist qualitative content data analysis.

Results

A total of 111 people participated in the study, of which 51 (45.9 %) were male and 60 (54.1 %) were female, while 58 (53.3 %) and 53 (47.7 %) were urban and rural residents, respectively. The factors that affect access to and acceptability of HATCS were categorized in four socio-ecological units of analysis: client-based factors (awareness, experiences, expectations, income, employment, family, HIV disclosure and food availability); community-based factors (care and support, stigma and discrimination and traditional healing); health facility-based factors (interactions with care providers, availability of care, quality of care, distance, affordability, logistics availability, follow up and service administration); and policy and standards (healthcare financing, service standards, implementation manuals and policy documents).

Conclusions

A socio-ecological perspective provides a useful framework to investigate the interplay among multilevel and interactive factors that impact on access to and acceptability of HATCS such as clients, community, institution and policy. Planners, resource allocators and implementers could consider these factors during planning, implementation and evaluation of HATCS. Further study is required to confirm the findings.

People living with HIV travel farther to access healthcare: a population-based geographic analysis from rural Uganda

Introduction

The availability of specialized HIV services is limited in rural areas of sub-Saharan Africa where the need is the greatest. Where HIV services are available, people living with HIV (PLHIV) must overcome large geographic, economic and social barriers to access healthcare. The objective of this study was to understand the unique barriers PLHIV face when accessing healthcare compared with those not living with HIV in a rural area of sub-Saharan Africa with limited availability of healthcare infrastructure.

Methods

We conducted a population-based cross-sectional study of 447 heads of household on Bugala Island, Uganda. Multiple linear regression models were used to compare travel time, cost and distance to access healthcare, and log binomial models were used to test for associations between HIV status and access to nearby health services.

Results

PLHIV travelled an additional 1.9 km (95% CI (0.6, 3.2 km), p=0.004) to access healthcare compared with those not living with HIV, and they were 56% less likely to access healthcare at the nearest health facility to their residence, so long as that facility lacked antiretroviral therapy (ART) services (aRR=0.44, 95% CI (0.24 to 0.83), p=0.011). We found no evidence that PLHIV travelled further for care if the nearest facility supplies ART services (aRR=0.95, 95% CI (0.86 to 1.05), p=0.328). Among those who reported uptake of care at one of two facilities on the island that provides ART (81% of PLHIV and 68% of HIV-negative individuals), PLHIV tended to seek care at a higher tiered facility that provides ART, even when this facility was not their closest facility (30% of PLHIV travelled further than the closest ART facility compared with 16% of HIV-negative individuals), and travelled an additional 2.2 km (p=0.001) to access that facility, relative to HIV-negative individuals (aRR=1.91, 95% CI (1.00 to 3.65), p=0.05). Among PLHIV, residential distance was associated with access to facilities providing ART (RR=0.78, 95% CI (0.61 to 0.99), p=0.044, comparing residential distances of 3–5 km to 0–2 km; RR=0.71, 95% CI (0.58 to 0.87), p=0.001, comparing residential distances of 6–10 km to 0–2 km).

Conclusions

PLHIV travel longer distances for care, a phenomenon that may be driven by both the limited availability of specialized HIV services and preference for higher tiered facilities.

Younger Age Predicts Failure to Achieve Viral Suppression and Virologic Rebound Among HIV-1-Infected Persons in Serodiscordant Partnerships

BACKGROUND

Antiretroviral therapy (ART) markedly reduces the risk of HIV-1 transmission in serodiscordant partnerships. We previously found that younger age and higher CD4 counts were associated with delayed initiation of ART by HIV-1-infected partners in serodiscordant partnerships. Among those initiating ART, we sought to explore whether those same factors were associated with failure to achieve viral suppression.

METHODS

In a prospective study of HIV-1-infected persons who had a known heterosexual HIV-1-uninfected partner in Kenya and Uganda [Partners Pre-Exposure Prophylaxis (PrEP) Study], we used Cox proportional hazards regression to evaluate correlates of viral nonsuppression (HIV-1 RNA >80 copies/ml).

RESULTS

Of 1,035 HIV-1-infected participants initiating ART, 867 (84%) achieved viral suppression: 77% by 6 months and 86% by 12 months. Younger age [adjusted hazard ratio (aHR) 1.05 for every 5 years younger; p = .006], lower pretreatment CD4 count (aHR 1.26; p = .009 for ≤250 compared with >250 cells/μl), and higher pretreatment HIV-1 RNA quantity (aHR 1.21 per log10; p < .001) independently predicted failure to achieve viral suppression. Following initial viral suppression, 8.8% (76/867) experienced virologic rebound (HIV-1 RNA >200 copies/ml): 6.3% and 11.5% by 6 and 12 months after initial suppression, respectively. Age was the only factor associated with increased risk of virologic rebound (aHR 1.33 for every 5 years younger; p = .005).

CONCLUSIONS

For HIV-1-infected persons in serodiscordant couples, younger age was associated with delayed ART initiation, failure to achieve viral suppression, and increased risk of virologic rebound. Motivating ART initiation and early adherence is a key to achieving and sustaining viral suppression.

Factors associated with adherence to Antiretroviral Therapy (ART) among adult people living with HIV and attending their clinical care, Eastern Ethiopia

BACKGROUND

To attain a successful treatment outcome, Antiretroviral Therapy (ART) treatment for people living with HIV requires more than 95% adherence level. The adherence level varies depending on different population contexts. Thus, the objective of this study was to investigate ART adherence level among HIV positive patients attending their clinical care in public health facilities in Harar and Dire Dawa, Eastern Ethiopia.

METHODS

We conducted a cross-sectional study among 626 ART attendees. Data were collected using a structured questionnaire with a face-to-face interview. ART adherence was considered when taking all antiretroviral treatment in a correctly prescribed doses at a right time (no dose missed or delayed for greater than or equal to 90 min) in the week prior to the study. Multivariable logistic analysis was applied to examine the association between the dependent and independent variables. Statistical significance was set at p-value <0.05.

RESULTS

The level of ART adherence was 85%. Adherence was more likely among patients of 35-44 years (AOR = 2.39; 95% CI = 1.15-5.01), had monthly income of 501.00-999.00 Ethiopian Birr (ETB) (AOR = 6.73; 95% CI = 2.71-16.75), no history of opportunistic infection (AOR = 2.81; 95% CI = 1.47-5.36), and had good family support (AOR = 2.61; 95% CI = 1.45-4.72). However, those who did not disclose their sero-status (AOR = 0.45; 95% CI = 0.21-0.97) and did experience depression (AOR = 0.36; 95% CI = 0.21-0.61) were less likely adherent than their counter parts.

CONCLUSIONS

The level of ART adherence was sub-optimal. Concerted and collaborative efforts through effective and efficient interventions are needed in view of the identified factors in order to improve the adherence level.

"Wan Kanyakla" (We are together): Community transformations in Kenya following a social network intervention for HIV care

BACKGROUND

In sub-Saharan Africa, failure to initiate and sustain HIV treatment contributes to significant health, psychosocial, and economic impacts that burden not only infected individuals but diverse members of their social networks. Yet, due to intense stigma, the responsibility for managing lifelong HIV treatment rests solely, and often secretly, with infected individuals. We introduce the concept of "HIV risk induction" to suggest that social networks of infected individuals share a vested interest in improving long-term engagement with HIV care, and may represent an underutilized resource for improving HIV/AIDS outcomes within high prevalence populations.

METHODS

In 2012, we implemented a 'microclinic' intervention to promote social network engagement in HIV/AIDS care and treatment. A microclinic is a therapy management collective comprised of a small group of neighbors, relatives, and friends who are trained as a team to provide psychosocial and adherence support for HIV-infected members. Our study population included 369 patients on ART and members of their social networks on Mfangano Island, Kenya, where HIV prevalence approaches 30%. Here we report qualitative data from 18 focus group discussions conducted with microclinic participants (n = 82), community health workers (n = 40), and local program staff (n = 39).

RESULTS

Participants reported widespread acceptability and enthusiasm for the microclinic intervention. Responses highlight four overlapping community transformations regarding HIV care and treatment, namely (1) enhanced HIV treatment literacy (2) reduction in HIV stigma, (3) improved atmosphere for HIV status disclosure and (4) improved material and psychosocial support for HIV-infected patients. Despite challenges, participants describe an emerging sense of "collective responsibility" for treatment among HIV-infected and HIV-uninfected members of social networks.

DISCUSSION

The lived experiences and community transformations highlighted by participants enrolled in this social network intervention in Western Kenya suggest opportunities to reframe the continuum of HIV care from a secretive individual journey into a network-oriented cycle of engagement.

Factors Associated with Retention to Care in an HIV Clinic in Gabon, Central Africa

Background

Retention to HIV care is vital for patients’ survival, to prevent onward transmission and emergence of drug resistance. Travelling to receive care might influence adherence. Data on the functioning of and retention to HIV care in the Central African region are limited.

Methods

This retrospective study reports outcomes and factors associated with retention to HIV care at a primary HIV clinic in Lambaréné, Gabon. Adult patients who presented to this clinic between January 2010 and January 2012 were included. Outcomes were retention in care (defined as documented show-up for clinical visits, regardless of delay) or LTFU (defined as a patient not retained in care; on ART or ART naïve, not returning to care during the study period with a patient delay for scheduled visits of more than 6 months), and mortality. Cox regression analysis was used to assess factors associated with respective outcomes. Qualitative data on reasons for LTFU were obtained from focus-group discussions.

Results

Of 223 patients included, 67.3% were female. The mean age was 40.5 (standard deviation 11.4) years and the median CD4 count 275 (interquartile range 100.5–449.5) cells/μL. In total, 34.1% were lost to follow up and 8.1% died. Documented tuberculosis was associated with increased risk of being LTFU (adjusted hazard ratio (aHR) 1.80, 95% confidence interval (95% CI) 1.05–3.11, P = 0.03), whereas early starting anti-retroviral therapy (ART) was associated with a decreased risk of LTFU (aHR 0.43, 95%CI 0.24–0.76, P = 0.004), as was confirmed by qualitative data.

Conclusions

Retention to HIV care in a primary clinic in Gabon is relatively poor and interventions to address this should be prioritized in the HIV program. Early initiation of ART might improve retention in care.

Implementation of electronic medical records requires more than new software: Lessons on integrating and managing health technologies from Mbarara, Uganda

Implementation lessons: • Technology alone does not necessarily lead to improvement in health service delivery, in contrast to the common assumption that advanced technology goes hand in hand with progress. • Implementation of electronic medical record (EMR) systems is a complex, resource-intensive process that, in addition to software, hardware, and human resource investments, requires careful planning, change management skills, adaptability, and continuous engagement of stakeholders. • Research requirements and goals must be balanced with service delivery needs when determining how much information is essential to collect and who should be interfacing with the EMR system. • EMR systems require ongoing monitoring and regular updates to ensure they are responsive to evolving clinical use cases and research questions. • High-quality data and analyses are essential for EMRs to deliver value to providers, researchers, and patients.

Factors Influencing Antiretroviral Adherence and Virological Outcomes in People Living with HIV in the Highlands of Papua New Guinea

Adherence to antiretroviral therapy (ART) is paramount for virological suppression and positive treatment outcomes. ART has been rapidly scaled up in Papua New Guinea (PNG) in recent years, however clinical monitoring of HIV+ individuals on ART is limited. A cross-sectional study was conducted at two major sexual health clinics in high HIV prevalence provinces in the Highlands Region of PNG to assess ART adherence, factors affecting adherence and the relationship between ART adherence and virological outcomes. Ninety-five HIV+ individuals were recruited and administered a questionnaire to gather demographic and ART adherence information whilst clinical data and pill counts were extracted from patient charts and blood was collected for viral load testing. Bivariate analysis was performed to identify independent predictors of ART adherence. Fourteen percent (n = 12) of participants showed evidence of virological failure. Although the majority of participants self-reported excellent ART adherence in the last seven days (78.9%, 75/91), pill count measurements indicated only 40% (34/84) with >95% adherence in the last month. Taking other medications while on ART (p = 0.01) and taking ART for ≥1 year (p = 0.037) were positively associated with adherence by self-report and pill count, respectively. Participants who had never heard of drug resistance were more likely to show virological failure (p = 0.033). Misconception on routes of HIV transmission still persists in the studied population. These findings indicate that non-adherence to ART is high in this region of PNG and continued education and strategies to improve adherence are required to ensure the efficacy of ART and prevent HIV drug resistance.

A combination SMS and transportation reimbursement intervention to improve HIV care following abnormal CD4 test results in rural Uganda: a prospective observational cohort study

BACKGROUND

Up to 50 % of HIV-infected persons in sub-Saharan Africa are lost from care between HIV diagnosis and antiretroviral therapy (ART) initiation. Structural barriers, including cost of transportation to clinic and poor communication systems, are major contributors.

METHODS

We conducted a prospective, pragmatic, before-and-after clinical trial to evaluate a combination mobile health and transportation reimbursement intervention to improve care at a publicly operated HIV clinic in Uganda. Patients undergoing CD4 count testing were enrolled, and clinicians selected a result threshold that would prompt early return for ART initiation or further care. Participants enrolled in the pre-intervention period (January - August 2012) served as a control group. Participants in the intervention period (September 2012 - November 2013) were randomized to receive daily short message service (SMS) messages for up to seven days in one of three formats: 1) messages reporting an abnormal result directly, 2) personal identification number-protected messages reporting an abnormal result, or 3) messages reading "ABCDEFG" to confidentially convey an abnormal result. Participants returning within seven days of their first message received transportation reimbursements (about $6USD). Our primary outcomes of interest were time to return to clinic and time to ART initiation.

RESULTS

There were 45 participants in the pre-intervention period and 138 participants in the intervention period (46, 49, and 43 in the direct, PIN, and coded groups, respectively) with low CD4 count results. Median time to clinic return was 33 days (IQR 11-49) in the pre-intervention period and 6 days (IQR 3-16) in the intervention period (P < 0.001); and median time to ART initiation was 47 days (IQR 11-75) versus 12 days (IQR 5-19), (P < 0.001). In multivariable models, participants in the intervention period had earlier return to clinic (AHR 2.32, 95 %CI 1.53 to 3.51) and earlier time to ART initiation (AHR 2.27, 95 %CI 1.38 to 3.72). All three randomized message formats improved time to return to clinic and time to ART initiation (P < 0.01 for all comparisons versus the pre-intervention period).

CONCLUSIONS

A combination of an SMS laboratory result communication system and transportation reimbursements significantly decreased time to clinic return and time to ART initiation after abnormal CD4 test results.

TRIAL REGISTRATIONS

Clinicaltrials.gov NCT01579214 , approved 13 April 2012.

Adherence to antiretroviral treatment by adults in a rural area of Botswana

Background: As antiretroviral therapy (ART) is becoming increasingly available to people in developing countries, ART adherence challenges assume ever greater significance. Often underlying treatment failure is the fact that suboptimal adherence to ART is the strongest predictor of failure to achieve viral suppression below the level of detection.

Objectives: The study's main objective was to identify factors affecting ART adherence levels, as well as the impact on immunologic and virologic responses in adult patients in one rural district in Botswana.

Methods: A cross-sectional quantitative survey, was used. Structured interviews were conducted with 300 ART patients between November 2011 and February 2012. Data were analysed, then presented in charts, graphs and frequency tables.

Results: The prevalence of non-adherence to ART was 14.0%. Motivators of good adherence included disclosure of HIV-positive status to more than one person, frequent adherence counselling, self-efficacy for adherence to ART, positive interactions between patients and healthcare providers; and using adherence partners. Barriers to adherence were forgetfulness, transportation costs to and from the clinic, time away from work and side-effects. There was a strong positive correlation between adherence, CD4 counts and viral load. Adherence was closely tied to immunologic and virologic improvements. Respondents with poor adherence were likely to have unsuppressed viral loads (OR 12.98, 95% CI 4.9–34).

Conclusion: Adherence to ART is closely tied to virologic, immunologic, and clinical outcomes. Increases in adherence levels resulted in significant improvements in these outcomes. Near perfect adherence, however, is required to maximise the likelihood of long-term clinical success, which could pose challenges to many ART patients, especially in resource-limited rural settings.

A qualitative study of patient motivation to adhere to combination antiretroviral therapy in South Africa

Taken as prescribed, that is, with high adherence, combination antiretroviral therapy (ART) has changed HIV infection and disease from being a sure predictor of death to a manageable chronic illness. Adherence, however, is difficult to achieve and maintain. The CAPRISA 058 study was conducted between 2007 and 2009 to test the efficacy of individualized motivational counselling to enhance ART adherence in South Africa. As part of the overall trial, a qualitative sub-study was conducted, including 30 individual interviews and four focus group discussions with patients in the first 9 months of ART initiation. Data were inductively analyzed, using thematic analysis, to identify themes central to ART adherence in this context. Four themes emerged that characterize the participants' experiences and high motivation to adhere to ART. Participants in this study were highly motivated to adhere, as they acknowledged that ART was 'life-giving', in the face of a large amount of morbidity and mortality. They were further supported by techniques of routine remembering, and highlighted the importance of good social support and access to supportive healthcare workers, to their continued success in negotiating their treatment. Participants in the current study told us that their adherence motivation is enhanced by free accessible care, approachable and supportive healthcare workers, broad social acceptance of ART, and past first-hand experiences with AIDS-related co-morbidity and mortality. Programs that include specific attention to these aspects of care will likely be successful in the long term.

Antiretroviral drug diversion links social vulnerability to poor medication adherence in substance abusing populations

Antiretroviral (ARV) medication diversion to the illicit market has been documented in South Florida, and linked to sub-optimal adherence in people living with HIV. ARV diversion reflects an unmet need for care in vulnerable populations that have difficulty engaging in consistent HIV care due to competing needs and co-morbidities. This study applies the Gelberg-Andersen behavioral model of health care utilization for vulnerable populations to understand how social vulnerability is linked to ARV diversion and adherence. Cross-sectional data were collected from a targeted sample of vulnerable people living with HIV in South Florida between 2010 and 2012 (n = 503). Structured interviews collected quantitative data on ARV diversion, access and utilization of care, and ARV adherence. Logistic regression was used to estimate the goodness-of-fit of additive models that test domain fit. Linear regression was used to estimate the effects of social vulnerability and ARV diversion on ARV adherence. The best fitting model to predict ARV diversion identifies having a low monthly income and unstable HIV care as salient enabling factors that promote ARV diversion. Importantly, health care need factors did not protect against ARV diversion, evidence that immediate competing needs are prioritized even in the face of poor health for this sample. We also find that ARV diversion provides a link between social vulnerability and sub-optimal ARV adherence, with ARV diversion and domains from the Behavioral Model explaining 25 % of the variation in ARV adherence. Our analyses reveal great need to improve engagement in HIV care for vulnerable populations by strengthening enabling factors (e.g. patient-provider relationship) to improve retention in HIV care and ARV adherence for vulnerable populations.

Adherence to antiretroviral therapy among HIV-infected children attending a donor-funded clinic at a tertiary hospital in Nigeria

The success of antiretroviral therapy (ART) depends on a high level of adherence to a life-long regimen of antiretroviral drugs (ARVs). Since the scale-up of access to ARVs in Nigeria, few studies have determined the level of adherence of ART among children. This study was undertaken to determine the level of ART adherence among paediatric patients at an outpatient clinic, the reasons for non-adherence, and the factors associated with adherence, according to caregivers' reports. Out of a total of 212 children, 183 (86%) were adherent in the three days preceding the interview, while 29 (14%) were not adherent. Drug exhaustion at home (16 children), followed by 'child slept through' (7 children) and 'caregiver away' were the most common reasons for a child having missed one or more ARV doses. Independent factors for adherence were male gender (odds ratio [OR] = 2.85; 95% confidence interval [CI]: 1.17-6.92) and attendance at last scheduled clinic appointment (OR = 4.76; 95% CI: 1.73-13.04). The caregiver's highest educational attainment, distance travelled to the clinic, use of medication reminders, formulation of ARVs, duration of HAART usage, age of the child and orphan status were not significantly associated with adherence to drug treatment. The overall level of adherence was high and similar to the rate reported prior to free access to ART services in Nigeria. Among child patients on HAART, there is a need to identify factors affecting clinic attendance and drug exhaustion at home.

Correlates of highly active antiretroviral therapy adherence among urban Ethiopian clients

There has been a massive expansion of highly active antiretroviral therapy (HAART) services in Ethiopia since 2005. To assess clients' self-reported adherence to HAART medication, a descriptive, comparative cross-sectional study was carried out among adults receiving HAART medication at the Zewditu Memorial Hospital ART clinic in Addis Ababa. Of 1 808 clients eligible for the study, 1 722 agreed to participate. The data were collected over six weeks in February and March 2010. Ordered and binary logistic regression models were applied to analyse the data. The majority of participants were over age 30 years, most were females, and 90% had some formal education. More than half reported being 'extremely sure' about their ability to take most or all of their medication. Self-reported adherence to the medication was generally good, as 62% said they had never missed a dose. The most commonly cited reason for missing medication was being busy (57.5%). The odds of ever missing a dose of HAART were lower for males (adjusted odds ratio [AOR]: 1.44; 95% confidence interval [CI]: 1.15-1.79), older persons (AOR: 0.98; 95% CI: 0.97-0.99), and those who did not drink alcohol regularly. Similarly, the odds of being self-confident about taking the medication properly were higher for males and for those who did not drink alcohol regularly (AOR: 0.48; 95% CI: 0.35-0.64). The odds of self-confidence in taking the medication were lower among those in lower income group. Those who reported an expenditure income of Birr 501-999 (AOR: 0.35; 95% CI: 0.24-0.49) or Birr 1 000-1 999 (AOR: 0.41; 95% CI: 0.29-0.60) had less self-confidence in taking their medication properly as compared to those who had an expenditure income of Birr 2 000 or more. There is a need to design and implement targeted adherence interventions that could lead to better treatment outcomes.

Personal coping strategies for managing the side effects of antiretroviral therapy among patients at an HIV/AIDS clinic in Uganda

The side effects of antiretroviral (ARV) medications negatively impact patients' quality of life and adherence to treatment. This study describes the burden of side effects from ARV treatment as experienced by a sample of HIV/AIDS patients and identifies the personal strategies they used to cope with the side effects. A total of 166 participants were recruited from a non-governmental HIV/AIDS clinic in Entebbe, Uganda. Most of the participants (76%) were females and the mean age of the sample was 38 years. Although the participants had taken ARV medications for an average period of nine months, a large proportion (76%) could not name the medications they were taking. The mean side-effects burden for the participants was five side effects. The most common adverse effects reported were tiredness, nightmares, mood swings, nausea, poor appetite, insomnia, vomiting and dizziness. The main strategies the patients used for coping with the side effects were those categorised under information-seeking, social-support seeking and positive-emotion-focused coping. However, 27% of the participants reported non-adherence to their ARV medications as a strategy to cope with the side effects. The findings show a significant relationship between the side-effects burden and a patient's age (r = 0.530, p ≤ 0.01) and level of education (r = 0.394, p ≤ 0.01). The findings indicate that in the short term after initiating ARV treatment most patients are able to cope with the high burden of side effects through appropriate strategies, but a sizable portion will fail to cope appropriately and thus resort to non-adherence. Clinicians should assist patients with continuous health education and counselling that focuses on appropriate strategies to cope with the side effects of ARVs in order to buffer the negative impact of HIV treatment on patients' adherence and quality of life.

The dynamic relationship between social support and HIV-related stigma in rural Uganda

BACKGROUND

Cross-sectional studies show that human immunodeficiency virus (HIV) stigma is negatively correlated with social support.

PURPOSE

The purpose of this study is to examine the bidirectional relationship between social support and HIV stigma.

METHODS

We collected quarterly data from a cohort of 422 people living with HIV in Uganda, followed for a median of 2.1 years. We used multilevel regression to model the contemporaneous and 3-month-lagged associations between social support and both enacted and internalized stigma.

RESULTS

Lagged enacted stigma was negatively correlated with emotional and instrumental social support, and lagged instrumental social support was negatively correlated with enacted stigma. Internalized stigma and emotional social support had reciprocal lagged associations.

CONCLUSIONS

Interventions to reduce enacted stigma may strengthen social support for people living with HIV. Improved social support may in turn have a protective influence against future enacted and internalized stigma.

[Characteristics of the patients "lost to follow-up" and determining factors of loss to follow-up to patients living with HIV at Ouagadougou, Burkina Faso]

The objective of this study is to describe the characteristics of the patients "lost to follow-up" and determining factors of lost to follow-up at the patients infected by HIV. This is a descriptive and analytical retrospective study made on patients with or not by HAART, registered in the Day hospital of Ouagadougou. Of 5118 adult patients studied, 402 (7.9%) lost to follow-up. Among these patients, 340 (84.5%) had an unknown vital status, 28 (7%) were alive and 34 (8.5%) died. Mean age was 37.5 years. After active research, 16 from 21 patients under HAART were in treatment interruption. The main factors associated with the loss of follow-up were: no schooling (p=0,008), residing outside the capital (p=0,002) and being infected with HIV2 (p< 10(-3)). The phenomenon of loss of follow-up is important and concerned mainly not informed patients.

'I am doing fine only because I have not told anyone': the necessity of concealment in the lives of people living with HIV in India

In HIV prevention and care programmes, disclosure of status by HIV-positive individuals is generally encouraged to contain the infection and provide adequate support to the person concerned. Lack of disclosure is generally framed as a barrier to preventive behaviours and accessing support. The assumption that disclosure is beneficial is also reflected in studies that aim to identify determinants of disclosure and recommend individual-level measures to promote disclosure. However, in contexts where HIV infection is stigmatised and there is fear of rejection and discrimination among those living with HIV, concealment of status becomes a way to try and regain as much as possible the life that was disrupted by the discovery of HIV infection. In this study of HIV-positive women and children in India, concealment was considered essential by individuals and families of those living with HIV to re-establish and maintain their normal lives in an environment where stigma and discrimination were prevalent. This paper describes why women and care givers of children felt the need to conceal HIV status, the various ways in which people tried to do so and the implications for treatment of people living with HIV. We found that while women were generally willing to disclose their status to their husband or partner, they were very keen to conceal their status from all others, including family members. Parents and carers with an HIV-positive child were not willing to disclose this status to the child or to others. Understanding the different rationales for concealment would help policy makers and programme managers to develop more appropriate care management strategies and train care providers to assist clients in accessing care and support without disrupting their lives.

Predictors of poor adherence among people on antiretroviral treatment in Cape Town, South Africa: a case-control study

A case-control study was conducted to describe the frequency with which structural- and individual-level barriers to adherence are experienced by people receiving antiretroviral (ARV) treatment and to determine predictors of non-adherence. Three hundred adherent and 300 non-adherent patients from 6 clinics in Cape Town completed the LifeWindows Information-Motivation-Behavioral Skills ART Adherence Questionnaire, the Substance Abuse and Mental Illness Symptoms Screener and the Structural Barriers to Clinic Attendance (SBCA) and Medication-taking (SBMT) scales. Overall, information-related barriers were reported most frequently followed by motivation and behaviour skill defects. Structural barriers were reported least frequently. Logistic regression analyses revealed that gender, behaviour skill deficit scores, SBCA scores and SBMT scores predicted non-adherence. Despite the experience of structural barriers being reported least frequently, structural barriers to medication-taking had the greatest impact on adherence (OR: 2.32, 95% CI: 1.73 to 3.12), followed by structural barriers to clinic attendance (OR: 2.06, 95% CI: 1.58 to 2.69) and behaviour skill deficits (OR: 1.34, 95% CI: 1.05 to 1.71). Our data indicate the need for policy directed at the creation of a health-enabling environment that would enhance the likelihood of adherence among antiretroviral therapy users. Specifically, patient empowerment strategies aimed at increasing treatment literacy and management skills should be strengthened. Attempts to reduce structural barriers to antiretroviral treatment adherence should be expanded to include increased access to mental health care services and nutrition support.

Antiretroviral adherence interventions in Southern Africa: implications for using HIV treatments for prevention

There is concern that the expansion of ART (antiretroviral treatment) programmes to incorporate the use of treatment as prevention (TasP) may be associated with low levels of adherence and retention in care, resulting in the increased spread of drug-resistant HIV. We review research published over the past year that reports on interventions to improve adherence and retention in care in Southern Africa, and discuss these in terms of their potential to support the expansion of ART programmes for TasP. We found eight articles published since January 2012, seven of which were from South Africa. The papers describe innovative models for ART care and adherence support, some of which have the potential to facilitate the ongoing scale- up of treatment programmes for increased coverage and TasP. The extent to which interventions from South Africa can be effectively implemented in other, lower-resource Southern African countries is unclear.

The enabling effect of food assistance in improving adherence and/or treatment completion for antiretroviral therapy and tuberculosis treatment: a literature review

Socioeconomic costs of HIV and TB and the difficulty of maintaining optimal treatment are well documented. Social protection measures such as food assistance may be required to offset some of the treatment related costs as well as to ensure food security and maintain good health of the affected individual and household. Programmes have started placing greater emphasis on treatment adherence and are looking for proven interventions that can optimize it. This paper looks at the effect of food assistance for enabling treatment adherence and reviews studies that used food assistance to promote adherence. Eight of ten studies found that provision of food can improve adherence and/or treatment completion for HIV care and treatment, ART and TB-DOTS. This indicates that food provision is not only a biological, but also a behavioural intervention, and underscores that unresolved food insecurity can be an impediment to treatment adherence and consequently to good treatment outcomes.

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.
