Purpose of Review We reviewed interventions to improve uptake and adherence to antiretroviral therapy (ART) in African countries in the Treat All era. Recent Findings ART initiation can be improved by facilitated rapid receipt of first prescription, including community-based linkage and point-of-care strategies, integration of HIV care into antenatal care and peer support for adolescents. For people living with HIV (PLHIV) on ART, scheduled SMS reminders, ongoing intensive counselling for those with viral non-suppression and economic incentives for the most deprived show promise. Adherence clubs should be promoted, being no less effective than facility-based care for stable patients. Tracing those lost to follow-up should be targeted to those who can be seen face-to-face by a peer worker. Summary Investment is needed to promote linkage to initiating ART and for differentiated approaches to counselling for youth and for those with identified suboptimal adherence. More evidence from within Africa is needed on cost-effective strategies to identify and support PLHIV at an increased risk of non-adherence across the treatment cascade.

Background Delay to start antiretroviral therapy (ART) and nonadherence compromise the health and wellbeing of people living with HIV (PLWH), raise the cost of care and increase risk of transmission to sexual partners. To date, interventions to improve adherence to ART have had limited success, perhaps because they have failed to systematically elicit and address both perceptual and practical barriers to adherence. The primary aim of this study is to determine the efficacy of the Supporting UPtake and Adherence (SUPA) intervention. Methods This study comprises 2 phases. Phase 1 is an observational cohort study, in which PLWH who are ART naïve and recommended to take ART by their clinician complete a questionnaire assessing their beliefs about ART over 12 months. Phase 2 is a randomised controlled trial (RCT) nested within the observational cohort study to investigate the effectiveness of the SUPA intervention on adherence to ART. PLWH at risk of nonadherence (based on their beliefs about ART) will be recruited and randomised 1:1 to the intervention (SUPA intervention + usual care) and control (usual care) arms. The SUPA intervention involves 4 tailored treatment support sessions delivered by a Research Nurse utilising a collaborative Cognitive Behavioural Therapy (CBT) and Motivational Interviewing (MI) approach. Sessions are tailored to individual needs and preferences based on the individual patient’s perceptions and practical barriers to ART. An animation series and intervention manual have been developed to communicate a rationale for the personal necessity for ART and illustrate concerns and potential solutions. The primary outcome is adherence to ART measured using Medication Event Monitoring System (MEMS). Three hundred seventy-two patients will be sufficient to detect a 15% difference in adherence with 80% power and an alpha of 0.05. Costs will be compared between intervention and control groups. Costs will be combined with the primary outcome in cost-effectiveness analyses. Quality adjusted life-years (QALYs) will also be estimated over the follow-up period and used in the analyses. Discussion The findings will enable patients, healthcare providers and policy makers to make informed decisions about the value of the SUPA intervention.

IntroductionNon-adherence to antiretroviral therapy (ART) is the main cause of viral non-suppression and its risk is increased by depression. In countries with high burden of HIV, there is a lack of trained professionals to deliver depression treatments. This paper describes the protocol for a 2-arm parallel group superiority 1:1 randomised controlled trial, to test the effectiveness and cost effectiveness of the TENDAI stepped care task-shifted intervention for depression, ART non-adherence and HIV viral suppression delivered by lay interventionists.Methods and analysisTwo hundred and ninety people living with HIV aged ≥18 years with probable depression (Patient Health Questionnaire=>10) and viral non-suppression (≥ 1000 HIV copies/mL) are being recruited from HIV clinics in towns in Zimbabwe. The intervention group will receive a culturally adapted 6-session psychological treatment, Problem-Solving Therapy for Adherence and Depression (PST-AD), including problem-solving therapy, positive activity scheduling, skills to cope with stress and poor sleep and content to target barriers to non-adherence to ART. Participants whose score on the Patient Health Questionnaire-9 remains ≥10, and/or falls by less than 5 points, step up to a nurse evaluation for possible antidepressant medication. The control group receives usual care for viral non-suppression, consisting of three sessions of adherence counselling from existing clinic staff, and enhanced usual care for depression in line with the WHO Mental Health Gap intervention guide. The primary outcome is viral suppression (<1000 HIV copies/mL) at 12 months post-randomisation.Ethics and disseminationThe study and its tools were approved by MRCZ/A/2390 in Zimbabwe and RESCM-18/19–5580 in the UK. Study findings will be shared through the community advisory group, conferences and open access publications.Trial registration numberNCT04018391.
