Developing an implementation science research agenda to improve the treatment and care outcomes among adolescents living with HIV in sub-Saharan Africa

In February 2016, Project SOAR convened a Technical Advisory Network meeting, attended by more than 50 international and domestic thought leaders in adolescent HIV care research and a small group of youth from southern Africa who are living with HIV. To prepare the groundwork for the meeting, SOAR produced a background paper synthesizing the literature on HIV continuum of care outcomes among adolescents living with HIV (ALHIV) in sub-Saharan Africa, where most adolescent cases of HIV are concentrated. This report presents the findings from the literature review and highlights from the Technical Advisory Network meeting. The first section is a summary of the review’s findings, specifically what we know about ALHIV along the care continuum. The second section of the report summarizes the outcomes from the meeting, including a set of priority research questions for the larger HIV community, as well as for Project SOAR, to consider addressing as part of new or ongoing studies

Conference: Women Learn from Women

On February 10, nearly one thousand women met at Barnard College to participate in a regional conference sponsored by Barnard, Columbia Women\u27s Liberation, Douglass College, NYU, Queens College, Sarah Lawrence, Hunter College, Richmond College, and SUNY/College at Old Westbury. Twelve workshops, each running morning and afternoon, allowed participants to attend two sessions, ranging from After Consciousness Raising, What? and How Far Will Legal Solutions Take Us? to Androgyny: The Range of Human Sexual Expression and Women Over Thirty: Fears, Expectations and Reality

Behavioral interventions for improving contraceptive use among women living with HIV

BACKGROUND: Contraception services can help meet the family planning goals of women living with HIV as well as prevent mother-to-child transmission. Due to antiretroviral therapy, survival has improved for people living with HIV, and more HIV-positive women may desire to have a child or another child. Behavioral interventions, involving counseling or education, can help women choose and use an appropriate contraceptive method. OBJECTIVES: We systematically reviewed studies of behavioral interventions for HIV-positive women intended to inform contraceptive choice, encourage contraceptive use, or promote adherence to a contraceptive regimen. SEARCH METHODS: Until 2 August 2016, we searched MEDLINE, CENTRAL, Web of Science, POPLINE, ClinicalTrials.gov and ICTRP. For the initial review, we examined reference lists and unpublished project reports, and we contacted investigators in the field. SELECTION CRITERIA: Studies evaluated a behavioral intervention for improving contraceptive use for family planning (FP). The comparison could have been another behavioral intervention, usual care, or no intervention. We also considered studies that compared HIV-positive versus HIV-negative women. We included non-randomized studies as well as randomized controlled trials (RCTs).Primary outcomes were pregnancy and contraception use, e.g. uptake of a new method or improved use or continuation of current method. Secondary outcomes were knowledge of contraceptive effectiveness and attitude about contraception or a specific contraceptive method. DATA COLLECTION AND ANALYSIS: Two authors independently extracted the data. One entered the data into RevMan and a second verified accuracy. We evaluated RCTs according to recommended principles. For non-randomized studies, we examined the quality of evidence using the Newcastle-Ottawa Quality Assessment Scale. Given the need to control for confounding factors in non-randomized studies, we used adjusted estimates from the models when available. Where we did not have adjusted analyses, we calculated the odds ratio (OR) with 95% confidence interval (CI). Due to varied study designs and interventions, we did not conduct meta-analysis. MAIN RESULTS: With three new reports, 10 studies from seven African countries met our eligibility criteria. Eight non-randomized studies included 8980 participants. Two cluster RCTs had 7136 participants across 36 sites. Three studies compared a special FP intervention versus usual care, three examined FP services integrated with HIV services, and four compared outcomes for HIV-positive and HIV-negative women.In four studies with high or moderate quality evidence, the special intervention was associated with contraceptive use or pregnancy. A study from Nigeria compared enhanced versus basic FP services. All sites had integrated FP and HIV services. Women with enhanced services were more likely to use a modern contraceptive method versus women with basic services (OR 2.48, 95% CI 1.31 to 4.72). A cluster RCT conducted in Kenya compared integrated FP and HIV services versus standard referral to a separate FP clinic. Women with integrated services were more likely to use more effective contraception (adjusted OR 1.81, 95% CI 1.24 to 2.63). Another cluster RCT compared an HIV prevention and FP intervention versus usual care in Kenya, Namibia, and Tanzania. Women at the special intervention sites in Tanzania were more likely to use highly effective contraception (adjusted OR 2.25, 95% CI 1.24 to 4.10). They were less likely to report unprotected sex (no condom use) at last intercourse (adjusted OR 0.23, 95% CI 0.14 to 0.40). Across the three countries, women at the special intervention sites were less likely to report any unprotected sex in the past two weeks (adjusted OR 0.56, 95% CI 0.32 to 0.99). A study in Côte d'Ivoire integrated HIV and FP services. HIV-positive women had a lower incidence of undesired pregnancy, but not overall pregnancy, compared with HIV-negative women (1.07 versus 2.38; reported P = 0.023). AUTHORS' CONCLUSIONS: The studies since 2009 focused on using modern or more effective methods of contraception. In those later reports, training on FP methods and counseling was more common, which may strengthen the intervention and improve the ability to meet clients' needs. The quality of evidence was moderate from the more recent studies and low for those from the 1990s.Comparative research involving contraceptive counseling for HIV-positive women is limited. The FP field needs better ways to help women choose an appropriate contraceptive and continue using that method. Improved counseling methods are especially needed for limited resource settings, such as clinics focusing on people living with HIV

\u27I need time to start antiretroviral therapy\u27: Understanding reasons for delayed ART initiation among people diagnosed with HIV in Lusaka, Zambia

INTRODUCTION: Rapid antiretroviral therapy (ART) initiation can improve patient outcomes such as viral suppression and prevent new infections. However, not everyone who can start ART does so immediately. METHODS: We conducted a qualitative study to inform interventions supporting rapid initiation in the \u27Test and Start\u27 era. We purposively sampled 20 adult patients living with HIV and a previous gap in care from ten health facilities in Lusaka, Zambia for interviews. We inductively analysed transcripts using a thematic, narrative approach. In their narratives, seven participants discussed delaying ART initiation. RESULTS: Drawing on messages gleaned from facility-based counselling and community information, many cited greater fear of rapid sickness or death due to imperfect adherence or treatment side effects than negative health consequences due to delayed initiation. Participants described needing time to \u27prepare\u27 their minds for a lifetime treatment commitment. Concerns about inadvertent HIV status disclosure during drug collection discouraged immediate initiation, as did feeling healthy, and worries about the impact of ART initiation on relationship dynamics. CONCLUSION: Findings suggest that counselling messages should accurately communicate treatment risks, without perpetuating fear-based narratives about HIV. Identifying and managing patient-specific concerns and reasons for the \u27need for time\u27 may be important for supporting individuals to rapidly accept lifelong treatment.Key messagesFear-based adherence messaging in health facilities about the dangers of missing a treatment dose or changing the time when ART is taken contributes to Zambian patients\u27 refusals of immediate ART initiationResponsive health systems that balance a stated need for time to accept one\u27s diagnosis and prepare to embark on a lifelong treatment plan with interventions to identify and manage patient-specific treatment related fears and concerns may support more rapid ART initiationPerceived social stigma around HIV continues to be a significant challenge for treatment initiation

Youth engagement in developing an implementation science research agenda on adolescent HIV testing and care linkages in sub-Saharan Africa

The importance of youth engagement in designing, implementing and evaluating programs has garnered more attention as international initiatives seek to address the HIV crisis among this population. Adolescents, however, are not often included in HIV implementation science research and have not had opportunities to contribute to the development of HIV-related research agendas. Project Supporting Operational AIDS Research (SOAR), a United States Agency for International Development-funded global operations research project, involved youth living with HIV in a meeting to develop a strategic implementation science research agenda to improve adolescent HIV care continuum outcomes, including HIV testing and counseling (HTC) and linkage to care

Retention and risk factors for attrition among adults in antiretroviral treatment programmes in Tanzania, Uganda and Zambia.

OBJECTIVES: We assessed retention and predictors of attrition (recorded death or loss to follow-up) in antiretroviral treatment (ART) clinics in Tanzania, Uganda and Zambia. METHODS: We conducted a retrospective cohort study among adults (≥18 years) starting ART during 2003-2010. We purposefully selected six health facilities per country and randomly selected 250 patients from each facility. Patients who visited clinics at least once during the 90 days before data abstraction were defined as retained. Data on individual and programme level risk factors for attrition were obtained through chart review and clinic manager interviews. Kaplan-Meier curves for retention across sites were created. Predictors of attrition were assessed using a multivariable Cox-proportional hazards model, adjusted for site-level clustering. RESULTS: From 17 facilities, 4147 patients were included. Retention ranged from 52.0% to 96.2% at 1 year to 25.8%-90.4% at 4 years. Multivariable analysis of ART initiation characteristics found the following independent risk factors for attrition: younger age [adjusted hazard ratio (aHR) and 95% confidence interval (95%CI) = 1.30 (1.14-1.47)], WHO stage 4 ([aHR (95% CI): 1.56 (1.29-1.88)], >10% bodyweight loss [aHR (95%CI) = 1.17 (1.00-1.38)], poor functional status [ambulatory aHR (95%CI) = 1.29 (1.09-1.54); bedridden aHR1.54 (1.15-2.07)], and increasing years of clinic operation prior to ART initiation in government facilities [aHR (95%CI) = 1.17 (1.10-1.23)]. Patients with higher CD4 cell count were less likely to experience attrition [aHR (95%CI) = 0.88 (0.78-1.00)] for every log (tenfold) increase. Sites offering community ART dispensing [aHR (95%CI) = 0.55 (0.30-1.01) for women; 0.40 (0.21-0.75) for men] had significantly less attrition. CONCLUSIONS: Patient retention to an individual programme worsened over time especially among males, younger persons and those with poor clinical indicators. Community ART drug dispensing programmes could improve retention

Reasons for Missing Antiretroviral Therapy: Results from a Multi-Country Study in Tanzania, Uganda, and Zambia.

OBJECTIVES: To identify the reasons patients miss taking their antiretroviral therapy (ART) and the proportion who miss their ART because of symptoms; and to explore the association between symptoms and incomplete adherence. METHODS: Secondary analysis of data collected during a cross-sectional study that examined ART adherence among adults from 18 purposefully selected sites in Tanzania, Uganda, and Zambia. We interviewed 250 systematically selected patients per facility (≥ 18 years) on reasons for missing ART and symptoms they had experienced (using the HIV Symptom Index). We abstracted clinical data from the patients' medical, pharmacy, and laboratory records. Incomplete adherence was defined as having missed ART for at least 48 consecutive hours during the past 3 months. RESULTS: Twenty-nine percent of participants reported at least one reason for having ever missed ART (1278/4425). The most frequent reason was simply forgetting (681/1278 or 53%), followed by ART-related hunger or not having enough food (30%), and symptoms (12%). The median number of symptoms reported by participants was 4 (IQR: 2-7). Every additional symptom increased the odds of incomplete adherence by 12% (OR: 1.1, 95% CI: 1.1-1.2). Female participants and participants initiated on a regimen containing stavudine were more likely to report greater numbers of symptoms. CONCLUSIONS: Symptoms were a common reason for missing ART, together with simply forgetting and food insecurity. A combination of ART regimens with fewer side effects, use of mobile phone text message reminders, and integration of food supplementation and livelihood programmes into HIV programmes, have the potential to decrease missed ART and hence to improve adherence and the outcomes of ART programmes

Project YES! Youth Engaging for Success: A randomized controlled trial testing a peer mentoring approach among HIV-positive adolescents and young adults in Ndola, Zambia

This research addresses the gaps in knowledge about how to best support adolescents and young adults transitioning to HIV self-management in the context of both child-focused and adult-focused HIV care settings. Johns Hopkins University, in partnership with the Arthur Davison Children’s Hospital, implemented this study through the USAID-funded Project SOAR (led by the Population Council)
