Experiences of support by unsuppressed adolescents living with HIV and their caregivers in Windhoek, Namibia: a qualitative study.

Background: Adolescents living with HIV (ALHIV) lag behind younger children and adults in the achievement of HIV care and treatment targets for HIV epidemic control. Treatment outcomes for adolescents may be influenced by their experiences with the support provided in HIV programs. We report on the experiences of virally unsuppressed adolescents and their caregivers with the current support in primary healthcare settings in Namibia. Methods: A qualitative descriptive and exploratory study was conducted in 13 public primary healthcare facilities in Windhoek, Namibia. A total of 25 in-depth interviews were conducted with unsuppressed adolescents (n = 14) and their caregivers (n = 11) between August and September 2023. The audio-recorded interviews were transcribed verbatim, and uploaded into ATLAS.ti software, and subjected to thematic content analysis. Findings: Three main support domains for the unsuppressed adolescents emerged from our analysis, namely: psychosocial, clinical and care, and socioeconomic support. The psychosocial support was delivered through peer support (teen clubs and treatment supporters) and enhanced adherence counselling mostly. The clinical and care support included implementing adolescent-friendly HIV services, differentiated service delivery approaches, and caregivers and healthcare worker care support for improved ART adherence, clinic attendance and continuous engagement in care. Socioeconomic support was provided for nutritional support, transport to access clinics, and school supplies, as well as income-generating projects. Conclusion: Psychosocial, clinical and care, and socioeconomic support are key elements in addressing the needs of adolescents challenged with achieving viral suppression. Health systems may benefit from whole-of-society and whole-of-government approaches to meet the needs of ALHIV that are beyond the scope of health service delivery such as nutritional, education and socioeconomic influences on both the health and well-being of ALHIV.

Policy and Programming Towards Addressing Treatment Gaps in Adolescents Living with HIV: A Content Analysis of Policy and Programme Documents in Namibia.

Adolescents living with HIV (ALHIV) face unique challenges resulting in persistent treatment gaps, particularly viral non-suppression. Country programs adopt policies, guidelines, and innovations, based on WHO recommendations and best practices from elsewhere. However, it is unclear to what extent these tools address the management of adolescents with viral non-suppression. We report on a review of guidelines for the provision of HIV services to ALHIV in Namibia. We conducted a systematic document review using Content Analysis and Thematic Analysis methodology, and the READ approach. We identified seven relevant policy documents, four of which somewhat addressed viral non-suppression (treatment gap) in ALHIV and outlined interventions to improve treatment outcomes in adolescents considering their lived experience and unique challenges. The persistent treatment gap may reflect policy implementation gaps in specifically addressing viral non-suppression. It may be worthwhile to leverage existing documents to develop specific operational guidance for ALHIV with unsuppressed viral loads.

Study analysing the potential gaps in the contents of policies and programme documents meant to address management of adolescents living with HIV with high viral load Viral load suppression is a huge challenge in adolescents living with HIV (ALHIV). Globally, adolescents lag when compared to children and adults in achieving viral suppression levels set for achieving HIV epidemic control. The WHO and global HIV program initiatives recommend evidence-based interventions to be included in policies and guidelines to address unique barriers adolescents face that prevent them from staying in HIV care and adhering to their medication. The extent to which country policies guide service providers in managing high viral load cases among adolescents is important in identifying and addressing the persistent gaps. We reviewed the contents of policies, guidelines and other programmatic documents that address HIV management in adolescents in Namibia to assess the extent to which the documents guide management of ALHIV who have high viral load. Seven documents addressing management of ALHIV in Namibia were identified. Four documents address viral suppression among adolescents and recommend some interventions to improve treatment outcomes in adolescents in general. The documents acknowledge the uniqueness of the adolescence, with unique experiences and challenges. However, the documents fall short in providing comprehensive and specific guidance in managing adolescents with high viral loads, for program implementers and direct service providers for ALHIV. The fragmented guidance on managing adolescents with unsuppressed viral loads may be leading to implementation gaps or uncertainties among service providers on how to manage unique cases. It would be essential to focus future efforts on consolidation or development of comprehensive guidance on management of adolescents with high viral load, and capacitating the healthcare providers and stakeholders engaged in addressing social determinants of health affecting these adolescents. A multisectoral approach may provide a pathway to improved viral suppression among ALHIV.

Determinants and rates of retention in HIV care among adolescents receiving antiretroviral therapy in Windhoek, Namibia: a baseline cohort analysis.

BACKGROUND: Long-term engagement in HIV care is essential to achieving and maintaining viral suppression. Adolescents living with HIV (ALHIV) experience many barriers to remaining engaged in care and treatment programs. Higher attrition among adolescents compared to adults remains a huge concern due to unique psychosocial and health systems challenges adolescents face, and recently the COVID-19 pandemic effects. We report on determinants and rates of retention in care in adolescents aged 10-19 years enrolled on antiretroviral therapy (ART) in Windhoek, Namibia. METHODS: A retrospective cohort analysis of routine clinical data of 695 adolescents aged 10-19 years enrolled for ART at 13 Windhoek district public healthcare facilities, between January 2019 and December 2021 was conducted. Anonymized patient data were extracted from an electronic database and registers. Bivariate and Cox proportional hazards analysis were performed to determine factors associated with retention in care among ALHIV at 6, 12, 18, 24 and 36 months. Retention in care trends were also described using the Kaplan-Meier survival analysis. RESULTS: The retention in care rates at 6, 12, 18, 24 and 36 months were 97.7%, 94.1%, 92.4%, 90.2%, and 84.6%, respectively. Our study population had predominantly treatment-experienced adolescents, who initiated ART between birth and 9 years (73.5%), were on treatment for > 24 months (85.0%), and on first-line ART (93.1%). After controlling for confounders, the risk of dropping out of care was increased for older adolescents aged 15-19 years (aHR = 1.964, 95% CI 1.033-3.735); adolescents on switched ART regimens (Second line + Third line regimen) (aHR = 4.024, 95% CI 2.021-8.012); adolescents who initiated ART at 15-19 years (aHR = 2.179, 95%CI 1.100-4.316); and male adolescents receiving ART at a PHC clinic (aHR = 4.322, 1.332-14.024). Conversely, the risk of ALHIV dropping out of care decreased for adolescents whose TB screen results were negative (aHR = 0.215, 95% CI 0.095-0.489). CONCLUSION: Retention in care rates among ALHIV in Windhoek do not meet the UNAIDS revised target of 95%. Gender-specific interventions are needed to keep male and older adolescents motivated and engaged in long-term care, and to promote adherence amongst those adolescents who were initiated on ART in late adolescence (15-19 years).

The Comparison of Teen Clubs vs. Standard Care on Treatment Outcomes for Adolescents on Antiretroviral Therapy in Windhoek, Namibia.

BACKGROUND: Adolescents living with HIV (ALHIV) are challenged to adhere to antiretroviral therapy (ART) and achieve and maintain virologic suppression. Group-based adherence support interventions, such as adherence clubs, have been shown to improve long-term adherence in ART patients. The teen club intervention was introduced in 2010 in Namibia to improve treatment outcomes for ALHIV by providing adherence support in a peer-group environment. Adolescents who have completed the full HIV disclosure process can voluntarily join the teen clubs. The current study compared treatment outcomes of ALHIV receiving ART at a specialized paediatric HIV clinic between 1 July 2015 and 30 June 2017 in Windhoek, Namibia. METHODS: A retrospective cohort analysis was conducted on routine patient data extracted from the electronic Patient Monitoring System, individual Patient Care Booklets, and teen club attendance registers. A sample of 385 adolescents were analysed: 78 in teen clubs and 307 in standard care. Virologic suppression was determined at 6, 12, and 18 months from study start date, and compared by model of care, age, sex, disclosure status, and ART regimen. Comparisons between adolescents in teen clubs and those receiving standard care were performed using the chi-square test, and risk ratios were calculated to analyze differences in ART adherence and virologic suppression. RESULTS: The average clinician-measured ART adherence was 89% good, 6% fair, and 5% poor amongst all adolescents, with no difference between teen club members and adolescents in standard care (p = 0.277) at 3 months. Virologic suppression over the 2-year observation period was 87% (68% fully suppressed <40 copies/ml and 19% suppressed between 40-999 copies/ml), with no difference between teen club members and those in standard care. However, there were statistically significant differences in virologic suppression levels between the younger (10-14 years) adolescents and older (15-19 years) adolescents at 6 months (p = 0.015) and at 12 months (p = 0.021) and between adolescents on first-line and second-line ART regimen at 6 months (p = 0.012), 12 months (p = 0.004), and 18 months (p = 0.005). CONCLUSION: The teen club model delivering psychosocial support only did not improve adherence and virologic suppression levels for adolescents in a specialized paediatric ART clinic, neither were they inferior to standard care. Considering the limitations of this study, teen clubs may still hold potential for improving adherence and virologic suppression levels for older adolescents, and more robust research on adherence interventions for adolescents with higher methodological quality is required.

The effects of Teen Clubs on retention in HIV care among adolescents in Windhoek, Namibia.

BACKGROUND: Adolescents living with HIV (ALHIV) are notably underserved by the national HIV programmes globally because of their unique needs. Of particular concern is limited access to and availability of adolescent-friendly antiretroviral therapy (ART) services, which contribute to poor retention in care in many sub-Saharan African countries. A Teen Club intervention was introduced in 2010 in Windhoek, Namibia, to improve retention in care among ALHIV through psychosocial support in a peer-group environment. OBJECTIVES: To compare the effects of the Teen Club intervention against standard care on retention in HIV care amongst adolescents at a Paediatric ART clinic. METHOD: A retrospective cohort analysis of adolescents aged 10-19 years receiving ART between July 2015 and June 2017 was conducted. Routine patient data were extracted from an electronic database and patient registers. A sample of 385 participants was analysed: 78 in the Teen Club and 307 in standard care. Retention was measured by assessing attendance to prescribed clinic visits up to 24 months. Comparisons were assessed with the Chi-square test, and Kaplan-Meier survival analysis was conducted to analyse differences in retention rates. RESULTS: The overall retention rate at 24 months among all adolescents was 90.1%, with no statistically significant difference between those in Teen Club (91%) and those in standard care (89%) (p = 0.956). Younger adolescents (10-14 years) had better retention rates at 24 months compared to older adolescents (15-19 years) (94% vs. 86%; p = 0.016). Retention rates were significantly higher for adolescents on first-line ART regimen (vs. second line: hazard ratio [HR] = 0.333; 95% confidence interval [CI] = 0.125-0.889); on ART ≥ 12 months (vs. < 12 months: HR =0.988; 95% CI = 0.977-0.999); and those to whom their HIV status was disclosed (HR = 0.131; 95% CI = 0.025-0.686). CONCLUSION: Group-based adherence support interventions did not improve retention rates for younger adolescents in specialised paediatric ART clinics but may still hold the potential for improving retention rates of older adolescents.
