Predictors and correlates of adherence to combination antiretroviral therapy (ART) for chronic HIV infection: a meta-analysis

Positive Psychological Factors Relate to Domain-Specific Cognition and Daily Functioning in Middle-Aged and Older Adults with HIV

Understanding positive psychological factors (PPFs; internal strengths, socioemotional support) that promote optimal health outcomes among people with HIV (PWH) is increasingly important. 122 PWH and 98 people without HIV (PWoH) were included in multivariable regressions, testing interactions between HIV status and PPFs on 7 cognitive domains and 2 daily functioning outcomes, controlling for depressive symptoms. Overall, higher internal strengths were related to better learning and memory, whereas higher socioemotional support was related to better processing speed and psychomotor speed. PWH had a stronger positive relationship between PPFs and verbal fluency than PWoH. Overall, higher internal strengths were associated with fewer daily functioning impairments; however, only PWoH showed fewer functional declines with higher socioemotional support. PWH may require greater socioemotional support to accommodate an increased burden of comorbidities leading to functional difficulties. Among PWH, bolstering PPFs may improve cognition; however, internal strengths may particularly benefit daily functioning.

Predicting Trajectories of Everyday Functioning in Adults Aging with HIV Using Latent Growth Mixture Modeling

As the U.S. population of people with HIV (PWH) ages, PWH exhibit high rates of adverse health outcomes including everyday functioning decline. We aimed to (1) identify trajectories of self-reported everyday functioning and (2) examine baseline predictors (demographics, cognitive domains, psychiatric and medical comorbidities, HIV-disease characteristics) of trajectories among PWH. 742 PWH completed up to five semi-annual visits over two years. Latent growth mixture modeling identified a linear 3-class solution with good statistical fit and interpretability. Most PWH (88%) had good baseline functioning with stability. Two classes had elevated baseline functional declines with worsening (7%) or improvement (5%). Greater depressive symptoms and motor skills impairment predicted higher odds of impaired functioning. Having chronic pulmonary disease increased odds of improvement, which may reflect connection to care, while older age increased odds of worsening. Most aging PWH demonstrate stable everyday functioning; however, interventions for depression and motor skills may improve functioning.

Urine tenofovir adherence testing: Perspectives of recently diagnosed South African adolescents and young adults with HIV accessing care via mobile HIV clinics

BACKGROUND

Adolescents and young adults (AYA) living with HIV face several challenges to engaging in HIV care, which can impact adherence to antiretroviral therapy (ART). Point-of-care (POC) diagnostics that detect tenofovir in urine may be a useful tool to support ART adherence, but perspectives from AYA in South Africa have not been explored.

METHODS

We conducted in-depth interviews (IDIs) among young people (age 18-24) newly diagnosed with HIV in Cape Town, and a focus group discussion (FGD) with HIV care providers to understand their perspectives regarding the use of POC urine tenofovir testing to support ART adherence. Transcripts were analyzed using Dedoose, with an iterative thematic approach.

RESULTS

Transcripts from 8 IDI participants and 8 FGD participants were included in the analysis. Major themes identified during analysis related to beliefs about POC urine adherence testing and recommendations for future clinical implementation. Most IDI participants indicated they would want to use the tests if clinically available, and both IDI and FGD participants believed the tests would be helpful to clinicians. Participants believed the tests could motivate people to take their ART regularly, either by reassuring them ART was present in their bodies, or to avoid the negative consequences of being found to be non-adherent. Drawbacks of POC adherence testing identified by respondents included not wanting to be caught skipping ART doses, concerns about privacy, how the test results would be explained, and adding to the amount of testing required for HIV clinical care.

CONCLUSIONS

AYA living with HIV in South Africa had favorable views toward POC tenofovir adherence testing and felt utilizing these tests in HIV clinical care would motivate people to remain adherent to ART.

Correlates of internalized stigma and antiretroviral therapy adherence among people living with HIV in the Volta region of Ghana

OBJECTIVE

HIV-related stigma is a major public health concern compromising the rights and health outcomes of many people living with HIV (PLWH). Its reduction is said to be critical in strengthening the continuous efforts targeted at preventing and controlling HIV, as it directly impacts antiretroviral treatment adherence. This study examines the association between HIV-related stigma and adherence to antiretroviral therapy (ART) among PLWH in one of the 16 administrative regions of Ghana, Africa.

METHODS

This descriptive cross-sectional study employed a survey to assess the factors affecting the utilization of ART among PLWH (n = 155) in the Volta region. The Center for Support Evaluation adherence index and internalized stigma of AIDS Tool were used to collect data on medication adherence and stigma, respectively. Data was analyzed using R statistical analysis software. Logistic regression models were performed to ascertain the predictors of ART utilization among PLWH.

RESULTS

A greater proportion (70%) of the study's participants reported adherence to ART. We found a positive association between HIV-related internalized stigma and medication adherence such that reporting high levels of stigma on average was associated with high levels of medication adherence [OR = 1.08, 95% CI:1.01, 1.15]. Older age was related to higher adherence while reporting more depressive symptoms was associated with low medication adherence.

CONCLUSION

Our findings show that stigma may serve as a facilitator instead of a barrier to adhering to antiretroviral medication. Although this contradicts common narratives about stigma's destructive effect, it is possible to promote good health-seeking behavior when the fear component of stigma is considered. To encourage medication adherence towards meeting UNAIDS' 95-95-95 agenda and better understand stigma's role, further research is required.

Health-Related Quality of Life in Young Adults With Perinatal HIV After Transfer to Adult Health Care in the Netherlands

INTRODUCTION

Health-related quality of life (HRQoL) in adult people with HIV is lower than that of the general population. Previously, no differences were detected in HRQoL of Dutch children with perinatal HIV (PHIV) compared with norm groups. In this study, we compared HRQoL of PHIV young adults (PHIV-YA, aged 18-30 years) with 2 norm groups, the healthy Dutch YA population and YA with various chronic conditions.

METHODS

Participants received questionnaires on HRQoL, adherence, and demographics. Additional social and health care-related variables were collected from patients' medical files. We explored correlations between HRQoL and demographic characteristics. Effect sizes (ES, Hedge s 'g with confidence intervals) were calculated to quantify the difference between PHIV-YA and norm groups.

RESULTS

Of 81 participants, 53 filled out the questionnaires. Compared with the healthy Dutch YA population, PHIV-YA aged 18-30 years had significantly lower HRQoL scores in the school/work subscale. PHIV-YA aged 26-30 years had significantly lower total, physical and psychosocial HRQoL scores as well. Participants in the older age category had lower HRQoL scores throughout all subcategories as compared with the younger age group. For PHIV-YA aged 18-25 years, lower scores on the school/work subscale were correlated with substance use and being born outside the Netherlands.

CONCLUSIONS

PHIV-YA had low HRQoL scores in school/work functioning compared with the healthy Dutch YA population. The circumstances driving these outcomes are likely to be multidimensional, including HIV infection, social background, and challenges in growing up with a chronic condition.

Including the Household: Individual, Community and Household Factors Affecting Antiretroviral Therapy Adherence After ART Initiation in Cape Town, South Africa

Antiretroviral therapy (ART) adherence is crucial for health outcomes of people living with HIV (PLHIV), influenced by a complex interplay of individual, community, and household factors. This article focuses on the influence of household factors, as well as individual and community factors, on ART adherence among PLHIV in Cape Town who have recently initiated ART. Baseline data for a cluster-randomized controlled trial were collected from 316 PLHIV in 12 districts in Cape Town between 6th May 2021 and 22nd May 2022. Zero-inflated Poisson models, with cluster-adjusted standard errors, were used to analyse the association between individual, household, and community factors and ART adherence measures. At the household-level, household support was associated with both better self-rated adherence (exp(β) = 0.81, z =  - 4.68, p < 0.001) and fewer days when pills were missed (exp(β) = 0.65, z =  - 2.92, p = 0.003). Psychological violence (exp(β) = 1.37, z = 1.97, p = 0.05) and higher household asset scores (exp(β) = 1.29, z =  - 2.83, p = 0.05) were weakly associated with poorer ART adherence. At the individual-level, male gender (exp(β) = 1.37, z = 3.95, p < 0.001) and reinitiating ART (exp(β) = 1.35, z = 3.64, p < 0.001) were associated with worse self-rated ART adherence; higher education levels (exp(β) = 0.30 times, z =  - 3.75, p < 0.001) and better HIV knowledge (exp(β) = 0.28, z =  - 2.83, p = 0.005) were associated with fewer days where pills were missed. At the community-level, community stigma was associated with worse self-rated ART adherence (exp(β) = 1.24, z = 3.01, p = 0.003). When designing interventions to improve ART adherence, household, individual and community factors should all be considered, particularly in addressing gender-based disparities, reducing stigma, tackling violence, and enhancing household support.Clinical Trial Number: Pan African Clinical Trial Registry, PACTR201906476052236.

Correlates of HIV treatment adherence self-efficacy among adolescents and young adults living with HIV in southwestern Uganda

Adherence to antiretroviral therapy (ART) among adolescents and young adults living with HIV (AYLHIV) in sub-Saharan Africa is sub-optimal compared to younger children and older adults. Adherence self-efficacy is one of the intrapersonal factors most strongly correlated with ART adherence. The role of adherence self-efficacy in ART adherence among AYLHIV is not well studied in Uganda. We enrolled 300 AYLHIV between October and December 2021 from an HIV clinic in southwestern Uganda. We collected information on adherence self-efficacy, HIV stigma, depression, self-management, and social skills. We used linear regression to estimate the association between adherence self-efficacy and the covariates of interest. At multivariable adjustment self-management (b = 0.29, 95% CI 0.23-0.35, p<0.001) and social skills (b = 0.16, 95% CI 0.08-0.24; p<0.001) were statistically significantly associated with adherence self-efficacy. The findings imply that interventions directed at enhancing self-management and social skills in AYLHIV may increase adherence self-efficacy and, potentially, HIV outcomes among AYLHIV.

Comparing pill counts and patient self-reports versus DBS tenofovir concentrations as ART adherence measurements with virologic outcomes and HIV drug resistance in a cohort of adolescents and young adults failing ART in Harare, Zimbabwe

BACKGROUND

Monitoring adherence presents a challenge in adolescents and it is prudent to explore several options for determining their level of adherence. This study sought to determine ART adherence levels in adolescents and young adults (on a tenofovir-containing regimen) failing ART as measured by self-reports, pill counts and DBS tenofovir concentrations and to compare levels of agreement among the methods and determine the ability of each method to predict virological suppression.

METHODS

This was a cohort study involving 107 adolescents and young adults between 10 and 24 years failing ART with viral load > 400copies/ml at enrolment. Pill count (PC) records, self-reports (SR) and DBS tenofovir concentrations (done by liquid Chromatography with tandem mass spectrometry (LC-MS/MS)) were used to determine adherence in adolescent participants failing ART in Harare. The latter was used as the reference method with a cut-off of 64 ng/ml. Determination of DBS tenofovir concentrations was also performed to rule out inadequate viral response due to low cumulative drug exposure despite high adherence (≥90 %). Longitudinal analysis was performed to determine the correlation of viral loads (VL) with adherence. The Kappa (k) coefficient was used to evaluate the level of agreement among the 3 methods.

RESULTS

Poor level of agreement was found between PC records and DBS tenofovir concentrations (k = -0.115). Moderate agreement was found between DBS and SR methods (k = 0.0557). Slight agreement was found between PC and SR methods (k = 0.0078). Adherence was dependent on age at HIV diagnosis (p = 0.0184) and ART initiation (p = 0.0265). Participants who were adherent were six times more likely to be suppressed at end point than their non-adherent counterparts (OR=5.7 CI 2.1 - 16.5, p < 0.0001).

CONCLUSIONS

Self-reported measure of adherence and pill counts exhibited poor agreement with the reference method used i.e. DBS tenofovir concentrations and are thus not effective methods of predicting virological suppression.

Switching Human Immunodeficiency Virus Therapy: Basic Principles and Options

The number of options for effective antiretroviral therapy (ART) is steadily increasing. Although older regimens may achieve the goal of virologic suppression, newer options can offer advantages in safety, tolerability, and convenience. In this article, we offer guiding principles for switching ART, highlighting reasons to pursue a switch and key factors to consider when selecting a new regimen.

Is fear of disease progression associated with antiretroviral therapy adherence in persons with HIV/AIDS?

We examined the mediating role of depression and anxiety on the relationship between fear of disease progression (FoP) and antiretroviral therapy (ART) adherence and the moderating role of social support in the FoP-depression/anxiety-ART adherence relationship in persons with HIV/AIDS (PWHA). 202 PWHA completed self-report measures. Simple mediation and moderated mediation analyses were performed. FoP was directly and negatively associated with ART adherence, and the mediating role of depression in this relationship was significant. Indirect effect of FoP mediated by anxiety on ART adherence was not significant. The moderating effect of social support was significant in the FoP-depression pathway, while the indirect effect of FoP on ART adherence mediated by depression was greatest at a higher level of social support and lower level of FoP. The results suggest the relevance of high FoP and depression-mediated FoP in ART adherence and social support may attenuate the negative impact of FoP.

Depression mediates the relationship between exposure to stigma and medication adherence among people living with HIV in low-resource setting: a structural equation modeling approach

This study hypothesizes that depression mediates the association between exposure to stigma and medication non-adherence in people living with HIV (PLHIV). We recruited 372 PLHIV from the Stigma, health-related Quality of life, antiretroviral Adherence, and Depression among people living with HIV (SQuAD-HIV) project, a multicenter cross-sectional study conducted between October 2021 and February 2022 among PLHIV attending six ART clinics in two geopolitical regions of northern Nigeria. A structural equation modeling (SEM) framework, utilizing the full information maximum likelihood estimator, was used to elucidate the pathways linking stigma, depression, and ART medication adherence, adjusting for sociodemographic characteristics. The total number of eligible participants analyzed (353) included 32.7% male PLHIV with a mean age (SD) of 39.42 (10.14). Being female was positively associated with adherence (β, 95% CI 0.335, 0.163-0.523, p-value < 0.001) but negatively associated with stigma (β, 95% CI - 0.334, - 0.561 to - 0.142, p-value = 0.001), while urban residence was negatively associated with stigma (β, 95% CI - 0.564, - 0.804 to - 0.340, p-value < 0.001). Our analysis also indicated that a higher level of experienced stigma was associated with decreased medication adherence. This association was partially mediated by depression (indirect effect = (0.256) (- 0.541) =  - 0.139; p-value < 0.01). The proportion of the association between stigma and medication adherence explained through mediation by depression was 35.6%. These findings underscore the need for targeted interventions aimed at lowering exposure to stigma among PLHIV to improve medication adherence.

One Year of Long-Acting Cabotegravir and Rilpivirine in People With Human Immunodeficiency Virus and Long Exposure to Antiretroviral Therapy: Data From the SCohoLART Study

Background

The aim of the study was to evaluate the 12-month cumulative probability of treatment discontinuation (TD) in people with human immunodeficiency virus (HIV; PWH) and a long exposure to antiretroviral therapy (ART) switching to long-acting cabotegravir and rilpivirine (CAB/RPV).

Methods

SCohoLART is a single-center, prospective, cohort study designed to collect both samples and clinical data from PWH with virological suppression who switched to bimonthly long-acting CAB/RPV. TD occurred at switch to another regimen for any reason including virological failure (VF); VF was defined as HIV RNA levels ≥50 copies/mL at 2 consecutive measurements or a single HIV RNA level ≥1000 copies/mL. Results were reported as median (interquartile range [IQR]) or frequency (percentage). Cumulative probabilities of TD were estimated using Kaplan-Meier curves.

Results

We evaluated 514 participants; 467 (90.9%) were male, and their median age (IQR) was 49 (40-56) years. At the time of switching, the median time from HIV diagnosis and the median duration of ART were 14.0 (IQR, 8.8-20.5) and 11.4 (7.9-17.4) years, respectively; before starting CAB/RPV, the median number of antiretroviral regimens was 3 (2-4). During a median study follow-up (IQR) of 13.1 (9.1-15.5) months, 52 PWH (10.1%) experienced TD, including 4 (0.8%) for VF. The 12-month cumulative probability of TD was 11% (95% confidence interval, 8%-14%). The main cause of TD was injection site reaction (15 participants [28.8%]).

Conclusions

The 1-year cumulative probability of TD with long-acting CAB/RPV was quite low in this cohort of people with a median exposure to ART of 10 years, in whom injection site reaction was the leading cause of TD. VFs were rare during study follow-up.

Addressing food insecurity in HIV care: perspectives from healthcare and social service providers in New York state

Ending the HIV epidemic in the United States will require addressing social determinants contributing to poor care engagement among people living with HIV (PLH), such as food insecurity. Food insecurity is associated with poor care engagement among PLH. Yet, few studies have examined the perspectives of healthcare and social services providers on addressing food insecurity in HIV care. Guided by the Social Ecological Model, we conducted semi-structured interviews with 18 providers in New York State to understand barriers and facilitators to addressing food insecurity in HIV care. Thematic analysis illustrated eight themes across various levels of the Social Ecological Model. At the patient-level, providers perceived patients' feelings of embarrassment, shame, and judgement, and low health literacy as barriers. At the provider-level, challenges included limited time. Facilitators included fostering strong, patient-provider relationships. Barriers at the clinic-level included limited funding, while clinic resources served as facilitators. At the community-level, challenges included intersecting stigmas arising from community norms towards PLH and people who receive food assistance and limited access to healthy food. Findings suggest the need to incorporate their insights into the development of interventions that address food insecurity in HIV care.

Latent class analysis of ART barriers among adolescents and young adults living with HIV in South Africa

This study examined adherence to antiretroviral therapy (ART) among adolescents and young adults living with HIV in South Africa. Using survey data from 857 youth on ART, the study employed latent class analysis to identify subgroups based on self-reported reasons for missed ART doses. Three distinct classes emerged: the largest class (85%) occasionally forgot to take their medication or missed a dose because others were around, the second class (9%) missed doses only due to feeling sick, and the third class (6%) faced multiple barriers such as forgetting, feeling sick, worrying about side effects, or doubting the effectiveness of ART. Youth who reported multiple barriers to adherence had significantly lower adjusted odds (AOR = 0.35, 95% CI = 0.16-0.78) of reporting 90% past month adherence compared to those who occasionally forgot their medication. Additionally, contextual factors such as food security, being treated well at the clinic, and being accompanied to the clinic were associated with higher odds of adherence. The findings highlight the importance of considering co-occurring barriers to adherence and tailoring interventions accordingly. Addressing contextual factors, such as ensuring food security and providing supportive clinic environments, is also crucial for promoting optimal adherence among adolescents and young adults living with HIV.

Detectable Virological Load and Associated Factors among People Living with HIV on Antiretroviral Treatment: A Retrospective Study

The complete and prolonged suppression of viral load is the primary objective of HAART in people living with HIV. Some people may experience therapeutic failure, while others may achieve virological suppression but are unable to maintain it, developing persistent or single detection of low-level viremia. This study aims to evaluate the determinants of a detectable viral load among patients on HAART to identify and address them promptly. In this retrospective study, all patients referring to the Infectious Disease Operative Unit of the Vito Fazzi Hospital in Lecce, Puglia, older than 18 years, receiving HAART for at least 12 months as of 30 June 2022, were included. For each patient, demographic characteristics such as age, sex, educational level, stable relationship, cohabitation, employment status, and information relating to habits and lifestyles such as physical activity, use of drugs, and substances or supplements for sport, abuse of alcohol, and smoking were collected. Degree of comorbidity was quantified according to the Charlson Comorbidity Index, and the presence of obesity and the COVID-19 infection was also considered. Univariable and multivariable logistic regression models were used to assess the association between patients' characteristics and the outcome. In the multivariable logistic regression model, the odds were lower for the duration of therapy (OR: 0.96; p = 0.0397), prescriber's perception of adherence to therapy (OR: 0.50; p < 0.0001), and Nadir CD4+ T-cell count (OR: 0.85; p = 0.0329), and higher for the presence of AIDS (OR: 1.89; p = 0.0423) and COVID-19 (OR: 2.31; p = 0.0182). Our findings support the early initiation of HAART to achieve virological suppression. Additionally, measures to improve adherence to therapy should be adopted to ensure better outcomes for patients.

Effects of telehealth-assisted interventions among people living with HIV/AIDS: A systematic review and meta-analysis of randomized controlled studies

INTRODUCTION

Taking antiretroviral therapy (ART) is a daily necessity for people living with HIV but these individuals experience multiple barriers and challenges to medication adherence. Interventions to support medication adherence have yielded effects in the expected direction, but the extent to which telehealth or virtually delivered interventions to promote adherence are effective among people living with HIV/AIDS remains unknown. We aimed to address this knowledge gap and inform future research and practice that promotes the well-being of people living with HIV/AIDs through telehealth interventions addressing medication use.

METHODS

A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted using the following databases: Academic Search Complete, Cochrane library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, MEDLINE, PubMed, OVID (UpToDate), and the Web of Science. Relevant full-text articles published through September 2021 were retrieved. The revised Cochrane risk of bias tool for randomized trials was used to assess the methodological quality of the included studies. A meta-analysis was performed using a random-effects model to calculate the pooled effects of telehealth-assisted interventions for people living with HIV/AIDS. Stata 16.0 was used for statistical analysis.

RESULTS

A total of 12 studies (N = 3557 participants) that used telehealth-assisted interventions for people living with HIV/AIDS were included. Telehealth interventions were found to increase the adherence to treatment (standardized mean difference [SMD]: 0.21; 95% confidence interval (CI): 0.03 to 0.40), to reduce depressive symptoms (SMD: -2,74; 95% CI: -3.39 to -2.09), and to improve perceived quality of life (SMD: 0.74; 95% CI: 0.37 to 1.10).

DISCUSSION

The meta-effects of telehealth-assisted interventions include significantly enhanced adherence to treatment, improved quality of life, and reduced depressive symptoms among people living with HIV/AIDS. These findings suggesting that delivering health management interventions remotely through telehealth-assisted modalities was both feasible and effective in yielding health benefits for people living with HIV/AIDS. Integrating telehealth-assisted interventions as a modality in HIV/AIDS care might support continuity of care and sustained well-being. Future research should evaluate telehealth intervention outcomes and examine mediating, moderating, or other tailorable variables affecting intervention effectiveness.

Antiretroviral Therapy Concealment Behaviors and their Association with Antiretroviral Therapy Adherence among People with HIV: Findings from the Florida Cohort Study

Little is known about HIV medication concealment behaviors and the effect of medication concealment on antiretroviral therapy (ART) adherence among people with HIV (PWH). This study aims to (1) to describe medication concealment behaviors and factors associated with these behaviors, and (2) assess the association between medication concealment and suboptimal ART adherence. The Florida Cohort Study enrolled adult PWH from community-based clinics around the state from October 2020 to September 2022 (n = 416, 62% aged 50+, 56% male, 44% non-Hispanic Black, 18% Hispanic). Participants responded to questions about sociodemographics, stigma, ART adherence (≥ 85%), symptoms of depression, social networks and disclosure to their networks, and actions to conceal ART to avoid inadvertent disclosure of their HIV status. Analyses were conducted using multivariable logistic regressions models. The most common concealment behavior was hiding ART while having guests over (32%), followed by removing ART labels (26%), and putting ART into a different bottle (16%). Overall, 43% reported ≥ 1 behavior. In multivariable models, depressive symptoms, incomplete disclosure of HIV to close social networks, and not having a close social network were associated with ART concealment. After adjusting for risk factors for suboptimal ART adherence, endorsing hiding medication while having guests was associated with suboptimal ART adherence (aOR 2.87, 95% CI 1.15-7.55). Taking any action and other individual behaviors were not associated. ART concealment behaviors were common but did not consistently negatively influence adherence when accounting for other factors. PWH may want to receive ART medications in ways that ensure privacy and reduce the risk of inadvertent disclosure.

Effect of a brief psychological intervention for common mental disorders on HIV viral suppression: A non-randomised controlled study of the Friendship Bench in Zimbabwe

BACKGROUND

For people living with co-morbid HIV and common mental disorders (CMD), it is not known whether a brief psychological intervention for CMD can improve HIV viral suppression.

METHODS

We conducted a prospective cohort study in eight primary care clinics in Harare, Zimbabwe, enrolling adults with co-morbid HIV and CMD. Six clinics provided the Friendship Bench (FB), a brief psychological intervention for CMD based on problem-solving therapy, delivered by lay counsellors. Two clinics provided enhanced usual care (EUC). The primary outcome was viral non-suppression after six months (viral load ≥400 copies/mL). Data were analysed using a difference-in-difference approach with linear regression of cluster-level proportions, adjusted for baseline viral non-suppression (aDiD). The secondary outcome was presence of CMD measured by the Shona Symptom Questionnaire.

RESULTS

In FB clinics, 407/500 (81.4%) participants had viral load results at baseline and endline: 58 (14.3%) had viral non-suppression at baseline and 41 (10.1%) at endline. In EUC clinics, 172/200 (86.0%) had viral load results at baseline and endline: 22 (12.8%) were non-suppressed at baseline and 26 (15.1%) at endline (aDiD = -7.3%; 95%CI 14.7% to -0.01%; p = 0.05). Of the 499 participants virally suppressed at baseline, the FB group had lower prevalence of non-suppression at endline compared to the EUC group (2.9% vs 9.3%; p = 0.002). There was no evidence of a difference in endline viral non-suppression by group among the 80 participants with non-suppression at baseline (53.5% vs 54.6%; p = 0.93). The FB group was less likely to screen positive for CMD at endline than the EUC group (aDiD = -21.6%; 95%CI -36.5% to -6.7%; p = 0.008).

CONCLUSION

People living with co-morbid HIV and CMD may benefit from receiving a low-cost mental health intervention to enhance viral suppression, especially if they are already virally suppressed. Research is needed to understand if additional adherence counselling could further improve viral suppression.

The Importance of Social Engagement in the Development of an HIV Cure: A Systematic Review of Stakeholder Perspectives

As research into the development of an HIV cure gains prominence, assessing the perspectives of stakeholders becomes imperative. It empowers stakeholders to determine priorities and influence research processes. We conducted a systematic review of the empirical literature on stakeholder perspectives. PubMed, Embase, Web of Science, and Scopus were searched for empirical, peer-reviewed articles, published before September 2022. Our analysis of 78 papers showed that stakeholders could be divided into three categories: people with HIV, key populations, and professionals. Following thematic synthesis, two main themes were distinguished: stakeholders' perspectives on HIV cure research and stakeholders' perspectives on HIV cure. Research on perspectives on HIV cure research showed that stakeholders' hypothetical willingness to participate (WTP) in HIV cure research was relatively high, while actual WTP was found to be lower. Studies also identified associated (individual) characteristics of hypothetical WTP, as well as facilitators and barriers to hypothetical participation. Additionally, we reported research on experiences of actual HIV cure research participation. Our analysis of stakeholder perceptions of HIV cure showed that most stakeholders preferred a cure that could eliminate HIV and outlined positive associated impacts. Furthermore, we observed that most included studies were conducted among PWHIV, and in the Global North. To empower stakeholders, we recommend that future research include an even greater diversity of stakeholders and incorporate theories of behavior to further explore how stakeholders decide to meaningfully engage in every stage of HIV cure research.

Effects of depression on medication adherence in HIV/AIDS patients: Korea HIV/AIDS cohort study

BACKGROUND

The number of people with HIV/AIDS has consistently increased in Korea since the first case of HIV/AIDS infection was reported in 1985. The depressive symptoms of patients with HIV/AIDS may lead to medication non-adherence. This study sought to investigate the cross-sectional and longitudinal association between depression and antiretroviral treatment adherence in the Korean HIV/AIDS population.

METHODS

We included participants of the Korea HIV/AIDS cohort study between 2009 and 2017. All information was collected at the enrollment and every annual visit, including sociodemographic characteristics, health-related behaviors, HIV/AIDS infection-related factors, depression score, and frequency of skipped medication. We performed a cross-sectional analysis of 601 participants registered between 2009 and 2017. Longitudinal data were evaluated by panel regression analysis in 515 patients who registered from 2009 to 2013.

RESULTS

In cross-sectional analysis, the HIV/AIDS patients with depressive symptoms were more likely to be non-adherent (adjusted OR = 0.52, 95 % CI 0.34, 0.79, p = 0.002). Medication adherence was significantly associated with a health-related lifestyle; the adjusted odds ratio of the non-smoking and non-drinking group was 1.75 (95 % CI 1.05, 2.90, p = 0.031). The longitudinal panel regression model revealed a significant negative impact of depression on medication adherence (adjusted OR = 0.50, 95 % CI 0.30, 0.84, p = 0.009). Non-smoking and non-drinking participants were 2.31 times more likely to adhere to antiretroviral treatment (95 % CI 1.29, 4.15, p = 0.005).

CONCLUSIONS

Our finding of depression and lifestyle modifications being significant contributors underscore the importance of proactive interventions to optimize the treatment outcomes of PLWH.

Perceptions of Long-Acting Injectable Antiretroviral Therapy Among People Living with HIV Who Use Drugs and Service Providers: a Qualitative Analysis in Rhode Island

Long-acting injectable antiretroviral therapy (LAI-ART) is a novel method to deliver HIV treatment, and the first regimen was approved in the USA in 2021. LAI-ART may mitigate barriers to oral treatment adherence, but little is known about LAI-ART perceptions among people living with HIV (PLWH) who use drugs, despite these populations facing greater barriers to treatment retention and ART adherence. We assessed LAI-ART perceptions and implementation considerations among PLWH who use drugs and health and ancillary service providers in Rhode Island. Data was collected from November 2021 to September 2022, and include in-depth interviews with 15 PLWH who use drugs and two focus groups with HIV clinical providers (n = 8) and ancillary service providers (n = 5) working with PLWH who use drugs. Data were analyzed thematically, with attention paid to how levels of structural vulnerability and social-structural environments shaped participants' LAI-ART perceptions and the HIV care continuum. Willingness to consider LAI-ART was impacted by HIV outcomes (e.g., viral suppression) and previous experiences with oral regimens, with those on stable regimens reluctant to consider alternative therapies. However, LAI-ART was seen as potentially improving HIV outcomes for PLWH who use drugs and enhancing people's quality of life by reducing stress related to daily pill-taking. Recommendations for optimal implementation of LAI-ART varied across participants and included decentralized approaches to delivery. HIV care delivery must consider the needs of PLWH who use drugs. Developing patient-centered and community-based delivery approaches to LAI-ART may address adherence challenges specific to PLWH who use drugs.

A Psychometric Evaluation and a Framework Test of the HIV Stigma Mechanisms Scale Among a Population-Based Sample of Men and Women Living with HIV in Central Uganda

HIV stigma is a critical barrier to HIV prevention and care. This study evaluates the psychometric properties of the HIV Stigma Mechanisms Scale (HIV-SMS) among people living with HIV (PLHIV) in central Uganda and tests the underlying framework. Using data from the PATH/Ekkubo study, (n = 804 PLHIV), we assessed the HIV-SMS' reliability and validity (face, content, construct, and convergent). We used multiple regression analyses to test the HIV-SMS' association with health and well-being outcomes. Findings revealed a more specific (5-factor) stigma structure than the original model, splitting anticipated and enacted stigmas into two subconstructs: family and healthcare workers (HW). The 5-factor model had high reliability (α = 0.92-0.98) and supported the convergent validity (r = 0.12-0.42, p < 0.01). The expected relationship between HIV stigma mechanisms and health outcomes was particularly strong for internalized stigma. Anticipated-family and enacted-family stigma mechanisms showed partial agreement with the hypothesized health outcomes. Anticipated-HW and enacted-HW mechanisms showed no significant association with health outcomes. The 5-factor HIV-SMS yielded a proper and nuanced measurement of HIV stigma in central Uganda, reflecting the importance of family-related stigma mechanisms and showing associations with health outcomes similar to and beyond the seminal study.

The Moderating Role of Social Support and HIV Stigma on the Association Between Depression and ART Adherence Among Young Thai Men Who Have Sex with Men

In Thailand, antiretroviral therapy (ART) programs still have difficulties reaching and promoting adherence among a key population - young men who have sex with men (YMSM) living with HIV. As such, we sought to examine potential psychosocial barriers that may contribute to suboptimal levels of ART adherence for this population. Data were drawn from a study of 214 YMSM living with HIV from Bangkok, Thailand. Linear regression models tested the association between depression and ART adherence, and whether social support and HIV-related stigma moderated that relationship. Multivariable models demonstrated social support was significantly associated with higher levels of ART adherence, and that there was a three-way interaction between depression, social support, and HIV-related stigma on ART adherence. These results further our understanding of the role of depression, stigma, and social support in ART adherence among Thai YMSM living with HIV, and that additional supports for YMSM with depression and HIV-related stigma are needed.

Cognitive Performance, as well as Depression, Alcohol Use, and Gender, predict Anti-Retroviral Therapy Adherence in a South African Cohort of People with HIV and Comorbid Major Depressive Disorder

Depression and cognitive impairment, which commonly coexist in people with HIV (PWH), have been identified as potential barriers to optimal antiretroviral therapy (ART) adherence. We investigated associations between cognitive performance, depression (as well as other sociodemographic, psychosocial and psychiatric variables) and ART adherence in a South African cohort of PWH with comorbid major depressive disorder (MDD). Cognitive performance and ART adherence were assessed at two time points 8 months apart (Nbaseline = 105, Nfollow-up = 81). Adherence was indicated by self-report, objective measures (Wisepill usage and plasma tenofovir-diphosphate levels), and HIV viral suppression. Mixed-effects regression models examined associations across both time points. Univariate models detected no significant associations between cognitive performance (globally and within-domain) and ART adherence. Multivariate modelling showed increased depression severity (β = - 0.54, p < 0.001) and problematic alcohol use (β = 0.73, p = 0.015) were associated with worse adherence as measured subjectively. Being female (OR 0.27, p = 0.048) and having better global cognitive performance (OR 1.83, p = 0.043) were associated with better adherence as indicated by viral suppression. This study identifies poor global cognitive performance, as well as depression and problematic alcohol use, as potential barriers to optimal ART adherence in PWH and comorbid MDD. Hence, clinicians could consider assessing for cognitive deficits, depression, and problematic alcohol use, and should endeavour to provide the appropriate support so as to improve adherence.

What are the determinants of antiretroviral therapy adherence among stable people living with HIV? A cross-sectional study in Cambodia

BACKGROUND

Understanding context-specific determinants of antiretroviral therapy (ART) adherence is crucial for developing tailored interventions for improving health outcomes and achieving the UNAIDS' third 95% target. This cross-sectional study explores factors associated with ART adherence among stable people living with HIV on ART in Cambodia.

METHODS

We used baseline survey data from a quasi-experimental study conducted in 2021. The participants were recruited from 20 ART clinics in nine provinces for face-to-face interviews. A structured questionnaire collected information on sociodemographic characteristics, ART adherence, perceived ART self-efficacy, mental health, quality of life, stigma, and discrimination. We conducted bivariate and multiple logistic regression analyses to identify factors associated with ART adherence.

RESULTS

Out of the 4101 participants, 86.5% reported adhering to ART in the past two months. The adjusted odds of ART adherence were significantly higher among participants in older age groups than those aged 15-29, participants with elevated cholesterol than those without it, participants who exhibited strong self-efficacy in health responsibility to maintain life than those with poor self-efficacy in health responsibility, participants who scored < 3 on the stigma and discrimination scale than those who scored ≥ 3, participants who scored ≥ 42 on the mental component of the quality-of-life scale than those who scored < 42. The adjusted odds of ART adherence were significantly lower in participants who earned > 301 USD per month than those who earned ≤ 100 USD per month.

CONCLUSION

The ART adherence rate among stable people living with HIV in this study was comparable to that of the general people living with HIV in Cambodia. The results suggest the need for innovative interventions to further reduce stigma and discrimination and strategies to improve the self-efficacy and mental health of people living with HIV to improve ART adherence.

Medication nonadherence: health impact, prevalence, correlates and interventions

Nonadherence to medicines is a global problem compromising health and economic outcomes for individuals and society. This article outlines how adherence is defined and measured, and examines the impact, prevalence and determinants of nonadherence. It also discusses how a psychosocial perspective can inform the development of interventions to optimise adherence and presents a series of recommendations for future research to overcome common limitations associated with the medication nonadherence literature. Nonadherence is best understood in terms of the interactions between an individual and a specific disease/treatment, within a social and environmental context. Adherence is a product of motivation and ability. Motivation comprises conscious decision-making processes but also from more 'instinctive', intuitive and habitual processes. Ability comprises the physical and psychological skills needed to adhere. Both motivation and ability are influenced by environmental and social factors which influence the opportunity to adhere as well as triggers or cues to actions which may be internal (e.g. experiencing symptoms) or external (e.g. receiving a reminder). Systematic reviews of adherence interventions show that effective solutions are elusive, partly because few have a strong theoretical basis. Adherence support targeted at the level of individuals will be more effective if it is tailored to address the specific perceptions (e.g. beliefs about illness and treatment) and practicalities (e.g. capability and resources) influencing individuals' motivation and ability to adhere.

Perceived Mistreatment in Health Care Settings and its Relationship with HIV Clinical Outcomes in HIV-positive People who Use Drugs in Vancouver, Canada

People living with HIV (PLWH) often experience stigma and discrimination by health care professionals. We investigated the prevalence of perceived mistreatment in health care settings and its associations with HIV clinical outcomes and health care-seeking behaviour using data from a long-running prospective cohort of PLWH who use drugs. Of the 857 participants included, 19% reported at least one instance of perceived mistreatment during the study period. In adjusted longitudinal analyses, perceived mistreatment was positively associated with not being on ART in the same follow-up period, and participants who reported perceived mistreatment were less likely to report seeing a physician in the subsequent follow-up period. Daily use of injection drugs was positively associated with reporting perceived mistreatment. These findings demonstrate the implications of negative health care interactions in a population that must consistently engage with the health care system, and the need for stigma-reducing educational interventions for health care professionals.

Association of mental health symptoms on HIV care outcomes and retention in treatment

OBJECTIVE

The purpose was to examine associations between HIV care engagement and mental health symptoms among persons living with HIV (PLWH) receiving ART. This study builds upon previous findings indicating a significant association between mental health and retention in HIV care,¹ while also advancing the literature by examining the impact of substance use on this link, as well as potential bidirectional associations.

METHOD

Participants of the current study were 493 patients who engaged in care and received antiviral therapy (ART) from Infectious Disease physicians between 2017 and 2019 in a large academic medical center.

RESULTS

Results from hierarchical regression analyses revealed that patients who missed more days of ART medication had higher depressive symptoms, even when accounting for the effect of demographic variables and alcohol use. Further, depressive symptoms predicted significant variance in number of "no show" visits, but was not individually predictive of ""no show"" visits beyond the effect of other HIV care outcomes (e.g., number of days of medication missed).

CONCLUSION

Findings reflect linkages among HIV treatment adherence, mental health, and substance use, and highlight the need to target mental health symptoms to improve outcomes among PLWH and prevent HIV transmission.

Association Between Belief in Medicine and Adherence to Antiretroviral Therapy Among Human Immunodeficiency Virus Adults in Zaira, Kaduna State, Nigeria

BACKGROUND

Negative perceptions of antiretroviral treatment (ART)'s efficacy and consequences may operate as roadblocks to adherence. This research aimed to determine the association between belief in medicine and adherence to antiretroviral therapy among HIV adults on ART in Ahmadu Bello University Teaching Hospital, Zaria, Kaduna State, Nigeria.

METHOD

Using a cross-sectional design, a systematic random sampling method was used to select respondents aged 18-64 years on antiretroviral therapy for at least six months at Ahmadu Bello University Teaching Hospital, outpatients of the President's Emergency Plan for AIDS Relief Clinic. Socio-demographics, belief in medicine and adherence to ART were obtained using a self-administered questionnaire. Descriptive statistics, chi-square test, and multiple logistic regression were used for data analysis.

RESULTS

Among the 385 people who took part in the study, about 67.5% were females and 32.5% were males. About 54% of adults adhered to ART. More than half (55.8%) of the respondents had negative perceptions (beliefs) of personal need for ART medication and about 42.3% of the respondents had more concerns about the potential negative effects of the ART medication. Government employment (odds ratio (OR) = 2.842, p = <0.01), self-employment (OR = 2.6, p = <0.001), and being divorced or widowed (OR = 2.0, p = <0.01), negative perceptions (beliefs) of personal need for the ART medication (adjusted OR (AOR) = 1.525, p=<0.01) and more concerns about the potential negative effects of the ART medication (AOR= 1.362, p = <0.05) were all significantly associated with ART adherence.

CONCLUSION

Employment, marital status and belief in medicine were associated with adherence to ART. Therefore, during adherence counseling, healthcare personnel should address respondents' false views and fears regarding ART medication in order to strengthen proper information and the benefits of ART. This article was previously presented as a meeting poster at the 36th Scientific Conference of the Nutrition Society of Malaysia (7th and 8th September 2021).

[Adherence to antiretroviral therapy by people living with HIV/AIDS in Florianópolis, Santa Catarina State, Brazil]

Adherence to antiretroviral therapy (ART) is essential to control HIV infections and avoid clinical complications and the development of resistant HIV strains. Several Brazilian municipalities have committed themselves to the 90-90-90 target, which aims at diagnosing 90% of HIV/AIDS cases, treating 90% of them, and virally suppressing 90% of them. However, only three Brazilian studies have assessed adherence to ART from secondary dispensing data. This study aimed to estimate the prevalence of adherence to treatment in the Municipality of Florianópolis, Santa Catarina State, Brazil, examining its association with demographic, health access, and clinical characteristics. A cross-sectional study was conducted using secondary national data from electronic medical records and Medication Logistic Control System (SICLOM) and Laboratory Test Control System (SISCEL) regarding people living with HIV/AIDS in the municipality from April 2020 to March 2021. We found an about 85% prevalence of adherence to ART. White men with follow-ups both in primary and secondary care showed greater adherence to treatment. Age and number of consultations directly related to adherence. Decentralizing care for users living with HIV/AIDS is the way to more comprehensive care but technical and ethical challenges still require solutions. Professional training, correct network referrals, and attention to confidentiality issues must be reinforced to expand treatment adherence.

Integrated Care as a Model for Interprofessional Disease Management and the Benefits for People Living with HIV/AIDS

INTRODUCTION

Today, antiretroviral therapy (ART) is effectively used as a lifelong therapy to treat people living with HIV (PLWH) to suppress viral replication. Moreover, PLWH need an adequate care strategy in an interprofessional, networked setting of health care professionals from different disciplines. HIV/AIDS poses challenges to both patients and health care professionals within the framework of care due to frequent visits to physicians, avoidable hospitalizations, comorbidities, complications, and the resulting polypharmacy. The concepts of integrated care (IC) represent sustainable approaches to solving the complex care situation of PLWH.

AIMS

This study aimed to describe the national and international models of integrated care and their benefits regarding PLWH as complex, chronically ill patients in the health care system.

METHODS

We conducted a narrative review of the current national and international innovative models and approaches to integrated care for people with HIV/AIDS. The literature search covered the period between March and November 2022 and was conducted in the databases Cinahl, Cochrane, and Pubmed. Quantitative and qualitative studies, meta-analyses, and reviews were included.

RESULTS

The main findings are the benefits of integrated care (IC) as an interconnected, guideline- and pathway-based multiprofessional, multidisciplinary, patient-centered treatment for PLWH with complex chronic HIV/AIDS. This includes the evidence-based continuity of care with decreased hospitalization, reductions in costly and burdensome duplicate testing, and the saving of overall health care costs. Furthermore, it includes motivation for adherence, the prevention of HIV transmission through unrestricted access to ART, the reduction and timely treatment of comorbidities, the reduction of multimorbidity and polypharmacy, palliative care, and the treatment of chronic pain. IC is initiated, implemented, and financed by health policy in the form of integrated health care, managed care, case and care management, primary care, and general practitioner-centered concepts for the care of PLWH. Integrated care was originally founded in the United States of America. The complexity of HIV/AIDS intensifies as the disease progresses.

CONCLUSIONS

Integrated care focuses on the holistic view of PLWH, considering medical, nursing, psychosocial, and psychiatric needs, as well as the various interactions among them. A comprehensive expansion of integrated care in primary health care settings will not only relieve the burden on hospitals but also significantly improve the patient situation and the outcome of treatment.

Grit is associated with psychological health among older sexual minority men

Objectives: Studies have shown that grit-defined as perseverance and passion for achieving one's long-term goals-is associated with improved health outcomes, including lower levels of psychological distress. However, the psychometric properties of the original Grit Scale (Grit-O Scale) has not been validated among sexual minority men (SMM). The present study aimed to validate the Grit-O Scale among a sample of older SMM and assess the relationships between the Grit-O Scale factors and symptoms of psychological distress.Method: We used data from a single visit of participants in the Multicenter AIDS Cohort Study (MACS) Healthy Aging longitudinal study. The sample included 981 older SMM (mean age = 61, SD = 8.5) with and without HIV. We conducted confirmatory factor analysis (CFA) to identify the two factors of the Grit-O Scale: consistency of interest and perseverance of effort. We also conducted a latent profile analysis (LPA) to identify distinct profiles of psychological distress from self-reported scales of depression, anxiety, and perceived stress.Results:The Grit-O Scale showed acceptable reliability estimates for the items with Cronbach's alpha reliability coefficients ranging from 0.77 to 0.82. The CFA identified the two factors of the Grit-O Scale with acceptable model fit (root mean square error of approximation = 0.058 [95% CI = 0.050, 0.067], comparative fit index = 0.95, Tucker-Lewis Index = 0.93, standardized root mean square residual = 0.07). The LPA yielded three mutually exclusive profiles of psychological distress (profile 1: low stress, anxiety, and depression; profile 2: high stress and depression and low anxiety; and profile 3: high stress, anxiety, and depression). In adjusted multinominal logistic regression analysis, we found that both higher levels of consistency of interest and perseverance of effort factors of the Grit-O Scale were significantly associated with decreased odds of being in profiles 2 and 3 compared with being in profile 1.Conclusion: Our findings support the use of the Grit-O Scale among older SMM. Grit factors could explain variability in the negative psychological symptoms among older SMM and warrant further investigation.Supplemental data for this article is available online at http://dx.doi.org/10.1080/13607863.2022.2032594.

A process and impact evaluation of a peer-led HIV self-management program

There is evidence that people with HIV (PWH) receive health-related benefits from having peer support and learning self-management skills. This evaluation assessed the effect of The Positive Life Workshop (TPLW)-a 7-session peer-led HIV self-management program-on psychosocial and HIV treatment outcomes. The overall sample included 1360 PWH who completed TPLW during 3/2015-2/2019. Surveys were administered before and after the program, and three months following program completion. Analyses examined changes in outcomes from pre-test to both post-test and 3-month follow-up using non-parametric tests. Subgroup analyses were conducted for 406 participants with ≥ 1 characteristic of the priority population for TPLW (i.e., recent HIV diagnosis, not taking antiretroviral therapy (ART), suboptimal ART adherence, unsuppressed viral load). In the overall sample, there were statistically significant improvements in HIV-related knowledge, social support, patient self-advocacy, and confidence in self-management between pre-test and post-test/3-month follow-up assessment. Analyses for the priority population showed significant increases from pre-test to 3-month follow-up in the proportion of participants who were ≥ 90 % adherent to ART (59-83 %, p < 0.01) and virally suppressed (42 % to 66 %, p < 0.01). The findings suggest the importance of ensuring HIV self-management interventions reach vulnerable populations of PWH who struggle with initiating and maintaining HIV-related health-promoting behaviors.

Virtual voices: examining social support exchanged through participant-generated and unmoderated content in a mobile intervention to improve HIV antiretroviral therapy adherence among GBMSM

Antiretroviral therapy (ART) adherence is suboptimal among gay, bisexual, and other men who have sex with men (GBMSM). Online interventions that incorporate social support represent new opportunities to improve adherence. This study focused on how social support was provided and sought within a technology-based ART adherence intervention. We coded and analyzed 1,751 messages. Within the social support messages, half of the time participants sought social support and half of the time they provided social support. Emotional and informational support were the most frequently exchanged forms. The most frequent topic that participants sought support around was interpersonal relationships (29%), followed by HIV care and treatment (28%). Similarly, 31% and 27% of messages in which participants provided support was related to HIV treatment and care and interpersonal relationships, respectively. HIV treatment and care issues most salient were ART adherence, lab results and upcoming tests, ART side effects, changes in ART regimens, and relationships with healthcare providers. Participants used the messaging feature in this intervention to spontaneously discuss and exchange support around HIV treatment and care. This analysis provided an opportunity to understand how participants informally interact with one another, how they seek and provide social support online, and their salient personal issues.

Acceptance Rate and Reasons for Rejection of Long Acting Injectable Antiretrovirals

In January 2021, cabotegravir/rilpivirine, the first extended-release injectable regimen for the treatment of Human Immunodeficiency Virus (HIV) was approved. Long-acting injections have the potential to improve adherence and viral suppression. We analyzed the acceptance rate of, and reasons for declining to switch to, the new regimen. During routine appointments, 102 people living with HIV (PLWH) were presented with information on the new medication and asked if they would like to switch from their current regimen. If they declined to switch, they were asked why. Sixty-nine percent of respondents declined to switch, with frequency of injections as the primary reason. Patients indicated they would be willing to switch if the interval between injections was longer. Forty percent of the patients accepting the injectable anti-retrovirals (ARVs) were not on any other medications. Barriers to switching to long-acting injectable ARVs include the need for more frequent provider visits, aversion to needles, and a perceived lack of evidence supporting the new medication.

Impact of antiretroviral therapy (ART) duration on ART adherence among men who have sex with men (MSM) living with HIV in Jinan of China

Background

Consistent and complete adherence is considered an essential requirement for patients on antiretroviral therapy (ART). This study aimed to evaluate the impact of ART duration on ART adherence, identify the trend of complete adherence, and compare the factors associated with ART adherence between short-term and long-term ART group among men who have sex with men (MSM) living with HIV in Jinan of China.

Methods

MSM living with HIV aged 18 or above and currently on ART were recruited from October to December 2020 using convenience sampling. Univariate and multivariable logistic regressions were used to evaluate the impact of ART duration on adherence and compare factors associated with ART adherence between subgroups. The Mann–Kendall test was used to identify the trend of complete adherence.

Results

A total of 585 participants were included in analysis, consisting of 352 on short-term ART (ART initiation ≤ 3 years) and 233 on long-term ART (ART initiation > 3 years). Significant difference of complete ART adherence between short-term and long-term ART group was detected (79.8% vs. 69.1%, P = 0.003). Multivariable analysis showed that men with longer ART duration were less likely to report complete ART adherence (AOR = 0.88, 95% CI 0.81–0.95). A descending trend of complete adherence was identified (Z = 1.787, P = 0.037). Alcohol use and lack of medication reminders were barriers to complete adherence for both of the subgroups.

Conclusions

Sustained efforts to encourage maintaining adherence for a lifetime are necessary, especially for those on long-term ART. Future interventions should be tailored to subgroups with different ART duration and individuals with specific characteristics.

Daily Associations Between Alcohol Consumption and Antiretroviral Therapy (ART) Adherence Among HIV-Positive Men Who Have Sex With Men

Alcohol consumption is one of the strongest predictors of suboptimal adherence to antiretroviral therapy (ART), however, there is little research that has investigated both within- and between-person associations of alcohol consumption and ART adherence at the event-level. In this secondary data-analysis, (N = 22) HIV-positive MSM prospectively reported daily alcohol consumption and ART adherence for 42-days. Multilevel models demonstrated (1) days in which participants reported consuming any alcohol was associated with 2.48 increased odds of ART non-adherence, compared to days in which participants reported no alcohol consumption, and (2) there was a non-significant trend indicating days in which participants reported consuming greater than their own average levels of alcohol was associated with increased odds of ART non-adherence. Findings highlight the importance of combining intervention efforts that address alcohol consumption and suboptimal ART adherence, and indicate a need for future research to investigate the mechanisms by which alcohol influences ART adherence.

Internet-based peer support interventions for people living with HIV: A scoping review

Peer support interventions for people living with HIV and AIDS (PLWHA) are effective, but their associated time and material costs for the recipient and the health system make them reachable for only a small proportion of PLWHA. Internet-based interventions are an effective alternative for delivering psychosocial interventions for PLWHA as they are more accessible. Currently, no reviews are focusing on internet-based interventions with peer support components. This scoping review aims to map the existing literature on psychosocial interventions for PLWHA based on peer support and delivered through the internet. We conducted a systematic scoping review of academic literature following methodological guidelines for scoping reviews, and 28 articles met our criteria. We summarized the main characteristics of the digital peer support interventions for PLWHA and how they implemented peer support in a virtual environment. Overall the reported outcomes appeared promising, but more robust evidence is needed.

Involvement, Perception, and Understanding as Determinants for Patient-Physician Relationship and Their Association with Adherence: A Questionnaire Survey among People Living with HIV and Antiretroviral Therapy in Austria

BACKGROUND

The relationship between patients and healthcare professionals (physicians) is the cornerstone of successful long-term antiretroviral therapy for people living with human immunodeficiency virus (HIV).

PURPOSE

This study aimed to investigate the connection between involvement, perception, and understanding as the basis for the patient-physician relationship and drug adherence, measured as the probability of non-adherence.

METHODS

In an online survey, people with HIV were asked about their relationship with their physicians and the extent to which they felt involved in treatment-related decisions. A statistical analysis was conducted to determine whether a better patient-physician relationship was associated with higher adherence to therapy. This was performed by univariate group comparison (Mann-Whitney-U, Fishers Exact Test) and logistic regression.

RESULTS

A total of 303 persons living with HIV participated in the survey, and 257 patients were included in the analysis. Overall, 27.6% were classified as non-adherent and self-reporting based on whether an antiretroviral therapy (ART) was taken in the past or how often the ART was interrupted. This proportion was significantly higher among patients aged 50-74 years (39.7%) and those with a longer therapy duration (9-15 years: 46.6%; from 15 years on: 55.8%). Therapy-non-adherent patients showed significantly lower scores in the relationship aspects understanding (2.68 vs. 3.03), participation (2.63 vs. 3.07), and perception (3.00 vs. 3.24) compared to adherent patients. Logistic regression analysis confirms that higher scores for understanding, involvement, and perception are strongly associated with a reduction in the risk of becoming non-adherent. This was true for all examined regression models, regardless of whether they were adjusted for the length of therapy and socio-demographic characteristics.

CONCLUSION

The results reinforce the need for awareness among health care professionals (HCP) regarding understanding, involvement, and perception as important aspects to improve the quality of the patient-physician relationship for high adherence levels with maximized non-adherence in ART management by PLWH.

Validation of the Korean Leeds satisfaction questionnaire in rheumatoid arthritis with Rasch models

OBJECTIVES

We conducted the cross-cultural adaptation and validation of the Leeds Satisfaction Questionnaire (LSQ) for patients with rheumatoid arthritis (RA) in Korea.

METHODS

The adaptation of the LSQ from English into Korean was based on guidelines for cross-cultural adaptation for self-report measures. Patients with RA were recruited from an outpatient clinic of a university hospital in South Korea. Validation of the Korean-LSQ with Rasch models was carried out using WINSTEPS. Model fit was determined by Infit and Outfit statistics (≥0.50 and ≤1.50), including the separation index (≥2.00) and reliability index (≥0.80).

RESULTS

The data set comprised 125 patients (82.4% female), with median (interquartile range) age 49.0 (37-57) years, and disease duration of 2.5 (1.2-3.8) years. The total and subscale scores of the Korean-LSQ demonstrated excellent or good test-retest reliability (0.88 for total, 0.71-0.82 for subscales), and items in the scale also revealed a high internal consistency (α = 0.93). The six subscales of the Korean-LSQ were found to have a good fit to the Rasch model and good reliability (Person separation index = 2.63 and reliability index = 0.87; item separation index = 37.03 and reliability index >0.99). In addition, the unidimensionality of the scale was confirmed by the principal component analysis based on the Rasch residuals.

CONCLUSION

Fit to the Rasch model confirmed that the construct validity, reliability, and unidimensionality of the LSQ were preserved following the adaptation into Korean. The Korean-LSQ is a valid and reliable tool for measuring satisfaction with care in Korean patients with RA.

An empiric tool to identify Kenyans living with HIV who will have unsuppressed viremia 18 months following treatment initiation to guide differentiated care models

Background

With the global push towards universal access to Antiretroviral Treatment (ART), patient numbers are increasing, further straining already under-resourced healthcare systems in sub-Saharan Africa. A simple scoring tool could be useful in optimizing differentiated service delivery by identifying individuals likely to have unsuppressed viral load.

Methods

Using existing data of patients accessing ART at public health facilities that were extracted from the Kenya Electronic Medical Record (KenyaEMR) and standard methods of developing a clinical prediction tool; we created and validated a risk scoring tool to identify persons likely to be virally unsuppressed at 18 months post-ART initiation. Data from the KenyaEMR were cleaned, merged and reviewed for completeness. We utilized multivariate modelling to determine key predictors of viral load suppression that could be measured in clinical settings.

Results

We assessed clinical reports of 3,968 patients on ART who had been on ART for at least 18 months and had at least one viral load result and were ≥ 18 years old. Of these, the majority (81%) were virally suppressed 18 months post-ART initiation. The final risk score included age, sex, body mass index at HIV diagnosis, number of years of formal education, disclosure status, and duration of time between HIV diagnosis and initiating ART. The maximum risk score was 78; a risk score of ≥22 was associated with unsuppressed viral load (>1000copies/mL). The area under the curve (AUC) for the probability of the risk score to correctly predict unsuppressed viral load was 0.55 (95% CI: 0.52 to 0.56). Internal and external validation showed similar predictive ability.

Conclusions

Routinely collected variables in a public HIV clinic medical record predicts, with modest accuracy, individuals likely to have unsuppressed HIV viremia 18 months after they initiate ART. The use and application of this tool could improve and complement efficiency in differentiated care models for patients on ART.

Estimating the minimum antiretroviral adherence required for plasma HIV-1 RNA viral load suppression among people living with HIV who use unregulated drugs

OBJECTIVES

Owing to advances in antiretroviral therapy (ART), we re-examined minimum ART adherence levels necessary to achieve sustained HIV-1 viral load (VL) suppression among people with HIV who use drugs (PHIV-PWUD).

DESIGN AND METHODS

We used data from ACCESS, a community-recruited prospective cohort of PHIV-PWUD in Vancouver, Canada. We calculated adherence using the proportion of days of ART dispensed in the year before each VL measurement. We used generalized linear mixed-effects models to identify adherence- and ART regimen-related correlates of VL suppression (<200 copies/ml). We employed probit regression models and generated dose-response curves to estimate the minimum adherence level needed to produce VL suppression in 90% of measures, stratified by regimen and calendar-year.

RESULTS

Among 837 ART-exposed PHIV-PWUD recruited between 1996 and 2017, the overall estimated adherence level necessary to achieve 90% VL suppression was 93% (95% confidence interval [CI]: 90-96). This differed by regimen: 69% (95% CI: 45-92) for integrase inhibitor (INSTI)-, 96% (95% CI: 92-100) for boosted protease inhibitor (bPI)-, and 98% (95% CI: 91-100) for non-nucleoside reverse transcriptase inhibitor-based regimens. In multivariable analysis, INSTI-based regimens were positively associated with VL suppression (vs. bPIs), while un-boosted PIs and other regimens were negatively associated. We observed a decreasing temporal trend of estimated adherence necessary for 90% VL suppression, dropping to 64% (95% CI: 50-77) during 2016-2017.

CONCLUSION

Although high levels of ART adherence were necessary to achieve consistent VL suppression, the minimum necessary adherence levels decreased over time. Overall, INSTI-based regimens performed the best, suggesting that they should be preferentially prescribed to PHIV-PWUD.

Preferences for a Game-Based SMS Adherence Intervention Among Young People Living with HIV in Ghana: A Qualitative Study

Young people living with HIV (YPLH) are at risk for poor treatment adherence. Short message service (SMS) interventions can improve adherence, yet few exist for YPLH. Our study investigated preferences for a game-based SMS intervention among YPLH in Ghana. Thirty-two YPLH, ages 18 to 24, were recruited from an HIV clinic to complete in-depth interviews. Content analysis of interview data revealed areas of technology use relevant to intervention implementation, including mobile communication preferences, internet access, and mobile game use. Participants reported high perceived utility towards intervention features: treatment reminders, gamification components, and involvement of supportive individuals (e.g., providers). Issues with privacy, literacy, and cultural/developmental appropriateness were among concerns raised. Suggestions were made for strengthening basic SMS features (e.g., using code words to protect privacy) and incorporating advanced features (e.g., simplifying game interactions). This novel approach may help engage YPLH in HIV care if carefully developed with attention towards its mechanisms and user preferences.

Perceptions About Local ART Adherence Norms and Personal Adherence Behavior Among Adults Living with HIV in Rural Uganda

Although misperceived norms often drive personal health behaviors, we do not know about this phenomenon in the context of antiretroviral therapy (ART) adherence. We conducted a cross-sectional study including all persons living with HIV (PLWH) on ART across eight villages in one parish in a rural region of southwestern Uganda. We used surveys to measure personal reports of ART adherence (not missing any doses of ART in the past 7 days was considered optimal adherence whereas missing doses was considered suboptimal adherence) and perceived norms about the local ART adherence norm (whether or not each individual thought 'most other PLWH on ART in this parish' missed any doses in the past 7 days). Multivariable Poisson regression models were used to estimate the association between perceived norms and personal adherence. Among 159 PLWH on ART (95% response rate), 142 (89%) reported no missed doses. However, 119 (75%) thought most individuals in this population of PLWH on ART were sub-optimally adherent. This misperception about the local ART adherence norm was prevalent in every subgroup of PLWH. Misperceiving the local ART adherence norm to be sub-optimal adherence was associated with a reduced likelihood of optimal adherence among married PLWH (adjusted relative risk [aRR] = 0.83; 95% confidence interval [CI] 0.71-0.97). The association was similar but imprecisely estimated for all PLWH (aRR = 0.91; 95% CI 0.82-1.01). Interventions to correct misperceived ART adherence norms as a stand-alone intervention or as a complement to other adherence promotion programs may influence ART adherence behavior and perhaps reduce HIV-related stigma.

Geriatric Conditions Associated with Nonadherence to Antiretroviral Therapy Among Older People with HIV: The Importance of Frailty

Poor compliance with medications is a growing concern in geriatric care and is increasingly more relevant among people living with HIV (PLWH) as they age. Our goal was to understand geriatric conditions associated with antiretroviral therapy (ART) nonadherence in a Medicare population of older PLWH. We analyzed Medicare data from PLWH aged 50 years or older who were continuously enrolled in fee-for-service Medicare from January 1, 2014 to June 30, 2015. Prevalent geriatric conditions (dementia, depression, falls, hip fracture, sensory deficits, osteoporosis, orthostatic hypotension, urinary incontinence, frailty) were identified in January 1, 2014-December 31, 2014. ART nonadherence was defined as <80% proportion of days covered (PDC) by at least two ART medications in January 1, 2015-June 30, 2015. We examined geriatric condition association with nonadherence using lowest Akaike Information Criterion multi-variate logistic models, controlling for age, sex, race, census region, substance use, Medicaid eligibility, and polypharmacy. Of 8778 PLWH, 23% (n = 2042) had <80% PDC. The average age was 60 years (standard deviation ±8), and >70% were males. In adjusted models, age was not associated with nonadherence, frailty status was the only geriatric condition associated with nonadherence [robust: reference, prefrail odds ratio (OR): 0.97, confidence interval (95% CI) 0.86-1.10, frail OR: 1.34 95% CI 1.11-1.61], and odds of nonadherence were lower for polypharmacy [OR: 0.48 (0.43-0.54)]. Our findings suggest that patient-centered care plans aimed at improving ART adherence among older PLWH would benefit from long-term surveillance; a deeper understanding of the role of frailty and polypharmacy, even at chronologically younger ages in PLWH.

Indirect comparison of 48-week efficacy and safety of long-acting cabotegravir and rilpivirine maintenance every 8 weeks with daily oral standard of care antiretroviral therapy in participants with virologically suppressed HIV-1-infection

Background

Efficacy and safety of long-acting cabotegravir (CAB) + rilpivirine (RPV) every 8 weeks (Q8W) versus daily oral standard of care (SoC) maintenance in treatment-experienced individuals with virologically suppressed human immunodeficiency virus type 1 (HIV-1) has not been directly compared in randomized clinical trials. This analysis aimed to indirectly compare these regimens.

Methods

An adjusted indirect treatment comparison of CAB + RPV Q8W with daily oral SoC was performed, using Phase 3 data from studies of CAB + RPV every 4 weeks (Q4W) vs SoC (ATLAS/FLAIR, n = 591 per group) and a Phase 3b trial of CAB + RPV Q8W vs Q4W (ATLAS-2M [excluding participants with prior CAB + RPV exposure]; n = 327 per group). Eligible participants were virologically suppressed (viral load < 50 HIV-1 ribonucleic acid (RNA) copies/mL), treatment-experienced individuals with HIV-1-infection. Treatment efficacy and safety assessments at Week 48 included virologic suppression and lack of virologic suppression (proportion of participants with plasma HIV-1 RNA < 50 copies/mL or ≥ 50 copies/mL, respectively; both as per FDA snapshot algorithm), CD4-cell count change from baseline, no virologic data, discontinuations due to adverse events (AEs), and overall AEs, serious AEs and Grade 3–5 AEs excluding injection-site reactions. A subgroup analysis stratified by baseline third active drug class was performed.

Results

Baseline characteristics between the Q4W arms of ATLAS/FLAIR and ATLAS-2M showed no significant differences or differences were not judged to be clinically relevant, apart from participants switching from a baseline third active drug class; more participants switched from integrase strand inhibitors in ATLAS/FLAIR, and from non-nucleoside reverse transcriptase inhibitors in ATLAS-2M. Injections of CAB + RPV Q8W showed no significant differences across efficacy and safety outcomes versus daily oral SoC. Univariate subgroup analysis found there were no significant differences on virologic suppression or lack of virologic suppression for any baseline third active drug class subgroup. These results suggest that CAB + RPV Q8W is non-inferior to daily oral SoC.

Conclusions

This analysis supports the therapeutic potential of CAB + RPV Q8W for virologically suppressed people living with HIV-1 infection seeking an alternative maintenance treatment option to daily oral SoC.

HIV and ART related knowledge among newly diagnosed patients with HIV under the universal-test-and-treat (UTT) policy in Johannesburg, South Africa

South Africa implemented Universal Test & Treat (UTT) guidelines in September 2016. We examine HIV/ART knowledge among newly diagnosed from a prospective study enrolling newly diagnosed HIV-positive adults, under same-day ART policy, at four primary health clinics in Johannesburg, South Africa. We describe factors associated with high HIV/ART related knowledge score among newly diagnosed patients using Poisson regression. We included 652 HIV positive adults (64.1% female; median age 33 years (IQR: 28-39). Overall, 539 (82.7%) patients were classified as having high HIV/ART knowledge, 14.7% medium knowledge and 2.6% had low knowledge. HIV/ART knowledge was mainly associated to high English literacy (aRR 0.9 Medium vs High, 95% CI: 0.8-0.9; aRR 0.7 for Low vs High: 95% CI: 0.6-0.9). However, patients who did not disclose their intentions for HIV test (aRR 0.9, not disclosed intentions vs having disclosed intentions to test, 95% CI: 0.8-0.9), participants who indicated concerns with ART (aRR 0.9 moderate to high vs low concerns, 95% CI: 0.8-0.9) were less likely to have high knowledge. Our results highlight a correlation between English literacy and good knowledge. There is a need to make information more accessible in a non-English language. Addressing this gap is critical in achieving the WHO targets.

Family Conflict Non-negotiation and HIV Disclosure Associated With ART Adherence in a Disadvantaged Population

Adherence to antiretroviral therapy (ART) is vital for reducing racial and gender disparities in morbidity and mortality among people living with HIV/AIDS (PLWH). Little research attention has been given to aspects of family functioning affecting ART adherence among PLWH vulnerable to disparities. Data were from n = 313 participants (93% African American) in the BEACON study, which recruited injection-drug-using PLWH on ART. Using factor analysis and longitudinal structural equation modeling, we found that current substance use and negative family conflict tactics (i.e., non-negotiation) predicted PLWH's lower probability of ART adherence at 12-month follow-up; and greater HIV disclosure to support network members predicted a higher probability of adherence. These findings suggest the importance of family and other support network members in this vulnerable population's ART adherence. Social network-focused interventions promoting prosocial response to conflict and negotiation skills are important for improving vulnerable PLWH's HIV outcomes and reducing health disparities.

Content validation of a new measure of patient-reported barriers to antiretroviral therapy adherence, the I-Score: results from a Delphi study

Background

Over a third of people living with HIV (PLHIV) have suboptimal adherence to antiretroviral therapy (ART). Measures of barriers to ART adherence often lack comprehensiveness. To help manage ART adherence barriers in HIV care, we are developing a new patient-reported outcome measure (PROM) of these barriers (the I-Score).

Methods

We assessed the content validity of 100 items (distinct barriers) to retain only those most relevant to both PLHIV and HIV health/social service providers. A web-based Delphi was conducted in Canada and France, collecting data from December 2018 to October 2019. Items were evaluated on relevance (the combined rated importance and actionability for HIV care of items among both PLHIV and providers); comprehensibility (rated item clarity); comprehensiveness (examined against our conceptual framework); cross-cultural equivalence (based on comparisons by questionnaire language (English, French) and country of residence). Pearson’s chi-square tests were used for comparisons by language, country, gender, and stakeholder group (PLHIV, providers).

Results

Panelists included 40 PLHIV and 57 providers (66% response rate). Thirty-one items were retained based on consensus thresholds for relevance (minimum: 50% for PLHIV, 60% for providers) and showed good comprehensibility and comprehensiveness, when compared to our conceptual framework (representation of: 6/6 domains, 15/20 subdomains). No significant difference in relevance based on language or country was found among retained items, suggestive of cross-cultural equivalence. Among all 100 items, only 6 significant differences on relevance were observed for gender. For 62 items, the relevance ratings of PLHIV and providers differed significantly, with providers showing greater endorsement of all items but one.

Discussion

The Delphi led to a much-needed item reduction. Remaining items highlight the panel’s multidimensional priorities for the PROM on ART adherence barriers, with few, if any, differences by language, country, and gender. While the analyses may lack generalizability and power, the sample size is considered adequate for a PROM validation study.

Conclusion

Retained items showed good content validity. The different patterns of item endorsement observed underscore the utility of engaging multiple stakeholder groups in PROM development for use in clinical practice. The greater endorsement of items by providers versus patients merits further investigation, including the implications of such differentials for measure development.

A conceptual model of alcohol use and adherence to antiretroviral therapy: systematic review and theoretical implications for mechanisms of action

Alcohol consumption is one of the most prevalent correlates of antiretroviral therapy (ART) adherence, yet causal processes underlying this association remain largely unexplored. The goal of this systematic review was to develop a conceptual model that describes the causal effect of alcohol consumption on ART nonadherence. We reviewed 230 studies that examined the association between alcohol consumption and ART adherence with three primary aims: (1) to replicate and extend previous reviews of the literature, (2) to summarize and critique study designs capable of answering questions about temporal overlap and (3) to summarize potential mechanisms of action. A model of alcohol-associated ART nonadherence was proposed to guide future work, integrating general theories of ART adherence and theory on the psychological and behavioral effects of alcohol intoxication. The conceptual model describes two mechanistic processes-prospective memory impairment and interactive toxicity beliefs/avoidance behaviors-involved in alcohol-associated intentional and unintentional nonadherence, respectively. This model can be used to guide future research on the causal processes involved in the frequently observed correlation between alcohol consumption and adherence.
