Integration of Telehealth Systems into HIV Care Services in Sub-Saharan Africa: A Scoping Review

Telehealth programs have been documented to help conserve scarce resources and enable the provision of quality and convenient patient care. Given the high HIV prevalence in sub-Saharan Africa, it is crucial for telehealth programs to be implemented. The purpose of this scoping review is to map the literature on telehealth in HIV care in sub-Saharan Africa, determine gaps in the utilisation of telehealth, and identify the barriers to implementation. A keyword search for studies reporting on telehealth in HIV care from PubMed, Research gate and gray literature was conducted, and studies published from 2015 to 2022, meeting the research criteria were included in the scoping review. Thematic content analysis was used to analyze findings from the included articles. Extraction of themes was performed using NVIVO version 12. Quality appraisal of the included studies was conducted using the mixed methods appraisal tool 2018 version. Database search retrieved 395 potentially eligible articles. Of these, 13 studies reported evidence of telehealth in HIV care. Included studies were conducted in South Africa, Kenya, Zambia, Zimbabwe, Togo, Mozambique, Tanzania, and Uganda. Three main themes emerged from the thematic content analysis: telehealth systems in sub-Saharan Africa are still at pilot stages or not widely implemented; users accept telehealth but raise concerns about privacy; and that low mobile phones ownership hampers telehealth implementation. The review revealed evidence for the effectiveness of telehealth in HIV care despite the presence of barriers. In this sense, it is recommended to adopt telehealth, which is cost effective, and improves access to healthcare. Keywords: HIV; Sub-Saharan Africa; Telehealth; Utilisation.

The acceptability of antidepressant treatment in people living with HIV in Malawi: A patient perspective

ABSTRACT Depression is common among people living with HIV (PLWH). Measurement-based care models that measure depression severity and antidepressant side effects, and use an algorithm to guide antidepressant prescription by non-specialized health workers represent an evidence-based treatment for severe depression in sub-Saharan Africa. We conducted in-depth interviews from June to December 2018 with eleven patients enrolled in Project SOAR-Mental Health, a pilot project integrating depression treatment into HIV care in Malawi. Patients treated with amitriptyline or fluoxetine participated in interviews exploring antidepressant acceptability through patient knowledge, side effect severity, pill burden, adherence, perceived efficacy, and tolerability. Patients described a lack of detailed antidepressant education from their providers. Variable, typically self-limiting side effects were reported from both amitriptyline and fluoxetine. While most side effects were mild, three patients reported functional impairment. Patients reported high adherence, though the additional pill burden was a challenge. Most patients found the antidepressants efficacious, tolerable, beneficial and acceptable. Although patient psychoeducation is notably lacking as a facet of clinical management, antidepressant prescription by primary care providers appears acceptable for comorbid severe depression in PLWH initiating HIV care in sub-Saharan Africa. Health workers should be mindful of dosing to minimise side effects and considerate of the additional pill burden. Trial registration: ClinicalTrials.gov ID [NCT03555669].

Measuring patient engagement with HIV care in sub-Saharan Africa: a scoping study.

IntroductionEngagement with HIV care is a multi‐dimensional, dynamic process, critical to maintaining successful treatment outcomes. However, measures of engagement are not standardized nor comprehensive. This undermines our understanding of the scope of challenges with engagement and whether interventions have an impact, complicating patient and programme‐level decision‐making. This study identified and characterized measures of engagement to support more consistent and comprehensive evaluation.MethodsWe conducted a scoping study to systematically categorize measures the health system could use to evaluate engagement with HIV care for those on antiretroviral treatment. Key terms were used to search literature databases (Embase, PsychINFO, Ovid Global‐Health, PubMed, Scopus, CINAHL, Cochrane and the World Health Organization Index Medicus), Google Scholar and stakeholder‐identified manuscripts, ultimately including English evidence published from sub‐Saharan Africa from 2014 to 2021. Measures were extracted, organized, then reviewed with key stakeholders.Results and discussionWe screened 14,885 titles/abstracts, included 118 full‐texts and identified 110 measures of engagement, categorized into three engagement dimensions (“retention,” “adherence” and “active self‐management”), a combination category (“multi‐dimensional engagement”) and “treatment outcomes” category (e.g. viral load as an end‐result reflecting that engagement occurred). Retention reflected status in care, continuity of attendance and visit timing. Adherence was assessed by a variety of measures categorized into primary (prescription not filled) and secondary measures (medication not taken as directed). Active self‐management reflected involvement in care and self‐management. Three overarching use cases were identified: research to make recommendations, routine monitoring for quality improvement and strategic decision‐making and assessment of individual patients.ConclusionsHeterogeneity in conceptualizing engagement with HIV care is reflected by the broad range of measures identified and the lack of consensus on “gold‐standard” indicators. This review organized metrics into five categories based on the dimensions of engagement; further work could identify a standardized, minimum set of measures useful for comprehensive evaluation of engagement for different use cases. In the interim, measurement of engagement could be advanced through the assessment of multiple categories for a more thorough evaluation, conducting sensitivity analyses with commonly used measures for more comparable outputs and using longitudinal measures to evaluate engagement patterns. This could improve research, programme evaluation and nuanced assessment of individual patient engagement in HIV care.

Stigma-directed services (Stig2Health) to improve 'linkage to care' for people living with HIV in rural Tanzania: study protocol for a nested pre-post implementation study within the Kilombero and Ulanga Antiretroviral Cohort.

Background: HIV-related stigma is a major barrier to the timely linkage and retention of patients in HIV care in sub-Saharan Africa, where most people living with HIV/AIDS reside. In this implementation study we aim to evaluate the effect of stigma-directed services on linkage to care and other health outcomes in newly diagnosed HIV-positive patients. Methods: In a nested project of the Kilombero and Ulanga Antiretroviral Cohort in rural Tanzania, we conduct a prospective observational pre-post study to assess the impact of a bundle of stigma-directed services for newly diagnosed HIV positive patients. Stigma-directed services, delivered by a lay person living with HIV, are i) post-test counseling, ii) post-test video-assisted teaching, iii) group support therapy and group health education, and iv) mobile health. Patients receiving stigma services (enrolled from 1 st February 2020 to 31 st August 2021) are compared to a historical control receiving the standard of care (enrolled from 1 st July 2017 to 1 st February 2019). The primary outcome is 'linkage to care'. Secondary endpoints are retention in care, viral suppression, death and clinical failure at 6-12 months (up to 31 st August 2022). Self-reported stigma and depression are assessed using the Berger Stigma scale and the PHQ-9 questionnaire, respectively. The sample size calculation was based on cohort data from 2018. Assuming a pre-intervention cohort of 511 newly diagnosed adults of whom 346 (68%) were in care and on antiretroviral treatment (ART) at 2 months, a 10% increase in linkage (from 70 to 80%), a two-sided type I error rate of 5%, and 90% power, 321 adults are required for the post-implementation group. Discussion: We expect that integration of stigma-directed services leads to an increase of proportions of patients in care and on ART. The findings will provide guidance on how to integrate stigma-directed services into routine care in rural sub-Saharan Africa.

Interventions to improve early retention of patients in antiretroviral therapy programmes in sub-Saharan Africa: A systematic review.

BackgroundSeveral interventions to improve long term retention (12 months and above) on treatment have been rigorously evaluated in Sub-Saharan Africa (SSA). However, research on interventions to improve retention of patients in the early stages of treatment (6 months) during this era of Universal Test and Treat has only recently emerged. The aim of this study is to systematically map evidence of interventions used to improve early retention of patients in antiretroviral therapy (ART) programmes in SSA.MethodsWe searched PubMed, EMBASE and Cochrane electronic databases to identify studies describing interventions aimed at improving early retention in ART treatment. We applied the methodological frameworks by Arksey and O’Malley (2005) and Levac et al. (2010). We also followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Interventions were categorized according to key broad areas in the existing literature.ResultsA total of 2,241 articles were identified of which 19 met the inclusion criteria and were eligible for this review, with the majority either being randomized control trials 32% (n = 6) or cohort studies 32% (n = 6). The studies reviewed were conducted in 11 SSA countries. The most common interventions described under key broad areas included: Health system interventions such as Universal Test-and-Treat, integration of ART initiation, HIV Testing and Counselling and Antenatal Care services and reduction of ART drug costs; Patient centered approaches such as fast track ART initiation, Differentiated Drug Delivery models and point of care HIV birth testing; Behavioral interventions and support through lay counselors, mentor mothers, nurse counselors and application of quality improvement interventions and financial incentives. Majority of the studies targeted the HIV positive adults and pregnant women.ConclusionWith the introduction of Universal Test-and-Treat and same-day initiation of ART, findings suggest that adoption of policies that expand ART uptake with the goal of reducing HIV transmission at the population level, promoting patient centered approaches such as fast track ART initiation, Differentiated Service Delivery models and providing adequate support through Mentor Mothers, lay and nurse counselors may improve early retention in HIV care in SSA. However, these interventions have only been tested in few countries in the region which points to how hard evidence based HIV programming is. Further research investigating the impact of individual and a combination of interventions to improve early retention in HIV care, including for various groups at high risk of attrition, is warranted across SSA countries to fast track the achievement of 95-95-95 Joint United Nations Programme on HIV/AIDS (UNAIDS) targets by 2030.

Integrating Care for Diabetes and Hypertension with HIV Care in Sub-Saharan Africa: A Scoping Review.

Introduction:Although HIV continues to have a high prevalence among adults in sub-Saharan Africa (SSA), the burden of noncommunicable diseases (NCD) such as diabetes and hypertension is increasing rapidly. There is an urgent need to expand the capacity of healthcare systems in SSA to provide NCD services and scale up existing chronic care management pathways. A scoping review mapped extant policy and evidence based literature on the feasibility of integrating NCD care with HIV in the region.Methods:A scoping review methodology was utilised to conduct a systematic search of peer-reviewed and grey literature published in English language and with no date limitation. A systematic search was conducted on PubMed, Embase, CINAHL, and the Cochrane library. The initial search identified 231 records considered for inclusion in this review. Twelve duplicate records were removed. The remaining 219 records were screened by title and abstract of which 165 records were excluded and 54 records were selected for full-text review. A further 16 records were excluded due to a lack of relevance or the unavailability of the full text article. Finally, 38 were charted and analysed thematically.Results:Thirty-eight studies were included. These comprised a range of different models to integrate NCD and HIV care in the region, reflecting differences in health system environments, and disease epidemiology. The studies provide a variety of evidence that integration of HIV and NCD care can be feasible and can improve clinical effectiveness and identify barriers and facilitators to integration and task shifting. The review confirms that integrated HIV and NCD care services is by-and-large feasible, being both clinically effective and cost-effective.Conclusion:The review may inform the understanding of how best to develop an integrated model of care service by reducing barriers to uptake, linkage and retention in HIV, diabetes and hypertension treatment in SSA countries.

Characteristics and impacts of nutritional programmes to address undernutrition of adults living with HIV in sub-Saharan Africa: a systematic review of evidence

Assessment of dietary diversity and nutritional support for children living with HIV in the IeDEA pediatric West African cohort: a non-comparative, feasibility study

BackgroundNutritional care is not optimally integrated into pediatric HIV care in sub-Saharan Africa. We assessed the 6-month effect of a nutritional support provided to children living with HIV, followed in a multicentric cohort in West Africa.MethodsIn 2014-2016, a nutritional intervention was carried out for children living with HIV, aged under 10 years, receiving antiretroviral therapy (ART) or not, in five HIV pediatric cohorts, in Benin, Togo and Côte d’Ivoire. Weight deficiency was assessed using two definitions: wasting (Weight for Height Z-score [WHZ] for children<5 years old or Body-Mass-Index for Age [BAZ] for ≥5 years) and underweight (Weight for Age Z-score [WAZ]) (WHO child growth standards). Combining these indicators, three categories of nutritional support were defined: 1/ children with severe malnutrition (WAZ and/or WHZ/BAZ <-3 Standard Deviations [SD]) were supported with Ready-To-Use Therapeutic Food (RUTF), 2/ those with moderate malnutrition (WAZ and/or WHZ/BAZ = [-3;-2[ SD) were supported with fortified blended flours produced locally in each country, 3/ those non malnourished (WAZ and WHZ/BAZ ≥-2 SD) received nutritional counselling only. Children were followed monthly over 6 months. Dietary Diversity Score (DDS) using a 24h recall was measured at the first and last visit of the intervention.ResultsOverall, 326 children were included, 48% were girls. At baseline, 66% were aged 5-10 years, 91% were on ART, and 17% were severely immunodeficient (CD4 <250 cells/mL or CD4%<15). Twenty-nine (9%) were severely malnourished, 63 (19%) moderately malnourished and 234 (72%) non-malnourished. After 6 months, 9/29 (31%) and 31/63 (48%) recovered from severe and moderate malnutrition respectively. The median DDS was 8 (IQR 7-9) in Côte d’Ivoire and Togo, 6 (IQR 6-7) in Benin. Mean DDS was 4.3/9 (sd 1.2) at first visit, with a lower score in Benin, but with no difference between first and last visit (p=0.907), nor by intervention groups (p-value=0.767).ConclusionsThis intervention had a limited effect on nutritional recovery and dietary diversity improvement. Questions remain on determining appropriate nutritional products, in terms of adherence, proper use for families and adequate energy needs coverage for children living with HIV.Trial registrationPACTR202001816232398, June 01, 2020, retrospectively registered.

Integrating diabetes, hypertension and HIV care in sub-Saharan Africa: a Delphi consensus study on international best practice

BackgroundAlthough HIV continues to have a high prevalence among adults in sub-Saharan Africa (SSA), the burden of noncommunicable diseases (NCD) such as diabetes and hypertension is increasing rapidly. There is an urgent need to expand the capacity of healthcare systems in SSA to provide NCD services and scale up existing chronic care management pathways. The aim of this study was to identify key components, outcomes, and best practice in integrated service provision for the prevention, identification and treatment of HIV, hypertension and diabetes.MethodsAn international, multi stakeholder e-Delphi consensus study was conducted over two successive rounds. In Round 1, 24 participants were asked to score 27 statements, under the headings ‘Service Provision’ and ‘Benefits of Integration’, by importance. In Round 2, the 16 participants who completed Round 1 were shown the distribution of scores from other participants along with the score that they attributed to an outcome and were asked to reflect on the score they gave, based on the scores of the other participants and then to rescore if they wished to. Nine participants completed Round 2.ResultsBased on the Round 1 ranking, 19 of the 27 outcomes met the 70% threshold for consensus. Four additional outcomes suggested by participants in Round 1 were added to Round 2, and upon review by participants, 22 of the 31 outcomes met the consensus threshold. The five items participants scored from 7 to 9 in both rounds as essential for effective integrated healthcare delivery of health services for chronic conditions were improved data collection and surveillance of NCDs among people living with HIV to inform integrated NCD/HIV programme management, strengthened drug procurement systems, availability of equipment and access to relevant blood tests, health education for all chronic conditions, and enhanced continuity of care for patients with multimorbidity.ConclusionsThis study highlights the outcomes which may form key components of future complex interventions to define a model of integrated healthcare delivery for diabetes, hypertension and HIV in sub-Saharan Africa.

Health Insurance Status of Pregnant Women and the Likelihood of Receipt of Antenatal Screening for HIV in Sub-Saharan Africa.

We investigated if initiating preventive care against HIV vertical transmission by antenatal HIV screening is independent of the patients' source of financial reimbursement for the care received in sub-Saharan Africa (SSA). Using information from the WHO's Global Health Expenditure Database and the Demographic Health Surveys Database for 27 sub-Saharan countries, we used Spearman's correlation and adjusted survey logistic regression to determine the potential relationship between enrollment in health insurance and the likelihood that expectant mothers would be offered antenatal HIV screening. We found that expectant mothers covered by health insurance were more than twice as likely to be offered antenatal screening for HIV compared to the uninsured. The likelihood differed by the type of insurance plan the expectant mother carried. Health insurance is more of a financial tool that this study finds to be necessary to boost the uptake of preventive and therapeutic HIV care in SSA. The ensuing disparity in receiving proper care could hinder the goals of 90-90-90 and the forthcoming 95-95-95 plan in SSA.

Developing an interprofessional transition course to improve team-based HIV care for sub-Saharan Africa

BackgroundWith funding from the United States Health Resources Service Administration (HRSA), a consortium of health professional training institutions from Africa developed HIV-specific, interprofessional, team-based educational resources to better support trainees during the transition period between pre-service training and professional practice.MethodsTen faculty members representing nine medical and nursing schools in sub-Saharan Africa (SSA) developed a training package of modules focused on core clinical, public health, interprofessional education (IPE), and quality improvement (QI) domains related to HIV service delivery. Curriculum development was informed by a rapid needs assessment of existing tools and future needs for HIV education across 27 SSA health professions training institutions. A total of 17 modules were developed, targeted at newly qualified health care professionals to be taught in a series of two-day workshops meant to complement existing institution specific HIV-curricula.ResultsBetween April and July 2019, a comprehensive case-based HIV training package was developed to support trainees in transition from pre-service training to independent professional practice. Each module, addressing different elements of interprofessional practice, was intended to be delivered in an interprofessional format. Thus far, 70 health professions training institutions in 14 countries have implemented the program; 547 educators facilitated STRIPE workshops, with a total of 5027 learners trained between September 2019 and September 2020.ConclusionsTo our knowledge this is the first IPE HIV-specific curriculum explicitly focused on enhancing the quality of training provided to graduating health care professionals working in SSA. The collaborative, cross-institutional, interprofessional approach to curriculum development provides a benchmark for how best-practice approaches to education can be disseminated in SSA.

Development of an interprofessional curriculum to improve team-based HIV care in sub-Saharan Africa: a training programme for undergraduate and early career health professionals

BackgroundDespite evidence of the impact of interprofessional education (IPE) strategies to improve the efficiency and quality of training, few undergraduate health professions education programmes in sub-Saharan Africa have implemented such approaches. Furthermore, few pre-service health professions educational institutions have developed educational interventions that target trainees during the transition between pre-service training and professional practice. We developed HIV-specific, interprofessional, team-based resources to better support trainees during the transition period. MethodsBetween April 1 and July 31, 2019 ten faculty members representing nine medical and nursing schools in Uganda and South Africa developed a training package focused on core clinical, public health, IPE, and quality improvement (QI) domains related to HIV service delivery. Using small-group learning principles, they developed 17 case-based modules to address a diverse set of HIV-related topics, including, but not limited to, HIV prevention, diagnosis, linkage to care, treatment, and management of opportunistic infections. All modules were aimed at newly, or nearly, qualified health-care professionals, including nurses, doctors, pharmacists, and laboratory scientists and were intended to be taught in workshops that will complement existing institution-specific HIV curricula. FindingsTraining resources were launched in August, 2019; in the following 6 months, 66 nursing and medical schools and their affiliated training sites in 14 countries in sub-Saharan Africa used the training modules to support interprofessional training for health professionals in training. In the first 6 months of the project, 3500 learners participated in the training. InterpretationFurther evaluation of this project and its effects on pedagogical approaches, trainee competencies, as well as wider changes in the organisation and delivery of HIV care, are warranted. The collaborative, interinstitutional, interprofessional approach to curriculum development could provide a benchmark for how best-practice approaches to education can be rapidly disseminated and scaled up across training programmes in Africa.

Differentiated HIV care in sub-Saharan Africa: a scoping review to inform antiretroviral therapy provision for stable HIV-infected individuals in Kenya

ABSTRACTMany gaps in care exist for provision of antiretroviral therapy (ART) in sub-Saharan Africa. Differentiated HIV care tailors provision of ART for patients based on their level of acuity, providing alternatives for where, by whom, and how often care occurs. We conducted a scoping review to assess novel differentiated care models for ART provision for stable HIV-infected adults in sub-Saharan Africa, and how these models can be used to guide differentiated care implementation in Kenya. A systematic search was conducted using PubMed, Embase, Web of Science, Popline, Cochrane Library, and African Index Medicus between January 2006 and January 2017. Grey literature searches and handsearching were also used. We included articles that quantitatively assessed the health, acceptability, and cost-effectiveness of differentiated HIV care. Two reviewers independently performed article screening, data extraction and determination of inclusion for analysis. We included 40 publications involving over 240,000 participants spanning nine countries in sub-Saharan Africa – 54.4% evaluated clinical outcomes, 23.5% evaluated acceptability outcomes, and 22.1% evaluated cost outcomes. Differentiated care models included: facility fast-track drug refills and appointment spacing, facility or community-based ART groups, community ART distribution points or home-based care, and task-shifting or decentralization of care. Studies suggest that these approaches had similar outcomes in viral load suppression and retention in care and were acceptable alternatives to standard HIV care. No clear results could be inferred for studies investigating task shifting and those reporting cost-effectiveness outcomes. Kenya has started to scale up differentiated care models, but further evaluation, quality improvement and research studies should be performed as different models are rolled out.

Retention in Differentiated Care: Multiple Measures Analysis for a Decentralized HIV Care and Treatment Program in North Central Nigeria.

ObjectiveDifferentiated care refers collectively to flexible service models designed to meet the differing needs of HIV-infected persons in resource-scarce settings. Decentralization is one such service model. Retention is a key indicator for monitoring the success of HIV treatment and care programs. We used multiple measures to compare retention in a cohort of patients receiving HIV care at “hub” (central) and “spoke” (decentralized) sites in a large public HIV treatment program in north central Nigeria.MethodsThis retrospective cohort study utilized longitudinal program data representing central and decentralized levels of care in the Plateau State Decentralization Initiative, north central Nigeria. We examined retention with patient- level (retention at fixed times, loss-to-follow-up [LTFU]) and visit-level (gaps-in-care, visit constancy) measures. Regression models with generalized estimating equations (GEE) were used to estimate the effect of decentralization on visit-level measures. Patient-level measures were examined using survival methods with Cox regression models, controlling for baseline variables.ResultsOf 15,650 patients, 43% were enrolled at the hub. Median time in care was 3.1 years. Hub patients were less likely to be LTFU (adjusted hazard ratio (AHR)=0.91, 95% CI: 0.85-0.97), compared to spoke patients. Visit constancy was lower at the hub (−4.5%, 95% CI: −3.5, −5.5), where gaps in care were also more likely to occur (adjusted odds ratio=1.95, 95% CI: 1.83-2.08).ConclusionDecentralized sites demonstrated better retention outcomes using visit-level measures, while the hub achieved better retention outcomes using patient-level measures. Retention estimates produced by incorporating multiple measures showed substantial variation, confirming the influence of measurement strategies on the results of retention research. Future studies of retention in HIV care in sub-Saharan Africa will be well-served by including multiple measures.

Identifying models of HIV care and treatment service delivery in Tanzania, Uganda, and Zambia using cluster analysis and Delphi survey

BackgroundOrganization of HIV care and treatment services, including clinic staffing and services, may shape clinical and financial outcomes, yet there has been little attempt to describe different models of HIV care in sub-Saharan Africa (SSA). Information about the relative benefits and drawbacks of different models could inform the scale-up of antiretroviral therapy (ART) and associated services in resource-limited settings (RLS), especially in light of expanded client populations with country adoption of WHO’s test and treat recommendation.MethodsWe characterized task-shifting/task-sharing practices in 19 diverse ART clinics in Tanzania, Uganda, and Zambia and used cluster analysis to identify unique models of service provision. We ran descriptive statistics to explore how the clusters varied by environmental factors and programmatic characteristics. Finally, we employed the Delphi Method to make systematic use of expert opinions to ensure that the cluster variables were meaningful in the context of actual task-shifting of ART services in SSA.ResultsThe cluster analysis identified three task-shifting/task-sharing models. The main differences across models were the availability of medical doctors, the scope of clinical responsibility assigned to nurses, and the use of lay health care workers. Patterns of healthcare staffing in HIV service delivery were associated with different environmental factors (e.g., health facility levels, urban vs. rural settings) and programme characteristics (e.g., community ART distribution or integrated tuberculosis treatment on-site).ConclusionsUnderstanding the relative advantages and disadvantages of different models of care can help national programmes adapt to increased client load, select optimal adherence strategies within decentralized models of care, and identify differentiated models of care for clients to meet the growing needs of long-term ART patients who require more complicated treatment management.

The Effect of Antiretroviral Stock-Outs on Medication Adherence Among Patients Living With HIV in Ghana: A Qualitative Study

Stock-outs of medications for antiretroviral therapy have been reported as a significant barrier to HIV care in sub-Saharan Africa, but patient responses to these shortages have not been fully described. The aim of our study was to employ qualitative methods to examine the role of medication stock-outs in contributing to treatment interruption among a sample of patients already engaged in care for HIV at Komfo Anokye Teaching Hospital in Kumasi, Ghana. We found that medication stock-outs presented a number of challenges to adherence for patients undergoing HIV treatment. Often, patients interrupted treatment until the stock-out ended. Those who did not interrupt treatment during stock-outs coped with shortages by stockpiling old medication or experienced clinic-initiated changes to their treatment regimens. Particularly in areas lacking the resources to monitor viral load or viral genotype, viral resistance could develop due to frequent unstructured treatment interruptions as a result of stock-outs.

Understanding data sources to measure patient retention in HIV care in sub-Saharan Africa.

Antiretroviral therapy (ART) programs in sub-Saharan Africa are moving towards universal treatment, yet the success of these programs is threatened by gaps within the continuum of HIV care. In this commentary, we seek to draw attention to the advantages and limitations of different data sources currently used for measuring retention in HIV care. Within the context of a piecemeal combination of imperfect data sources, selecting a gold standard of collecting retention data is difficult. Currently, our data systems for measuring retention provide an incomplete picture of the health of our national ART systems and, thus, the health of our patients.

Effective interventions to improve young adults’ linkage to HIV care in Sub-Saharan Africa: a systematic review

ABSTRACTHIV/AIDS remains a major public health problem despite the efforts to prevent and decrease its spread. Sub-Saharan Africa (SSA) represents 70% of the global number of people living with HIV and 73% of all HIV/AIDS-related deaths. Young adults age 15–24 years are disproportionately impacted by HIV/AIDS in SSA with 34% of people living with HIV (PLWHIV) and 37% of newly diagnosed individuals being in this age group. It is important that PLWHIV be linked to care to facilitate antiretroviral therapy (ART) initiation and limit the spread of infection. We conducted a systematic literature review to identify effective interventions designed to improve linkage to care among HIV-infected young adults in SSA. One hundred and forty-six titles and abstracts were screened, 28 full-texts were reviewed, and 6 articles met the inclusion and exclusion criteria. Home-based HIV counseling and testing, home-based HIV self-testing, and mobile HIV counseling and testing followed by proper referral of HIV-positive patients to HIV care were effective for improving linkage of young adults to care. Other factors such as referral forms, transportation allowance, home initiation of HIV care, and volunteer escort to the HIV treatment clinic were effective in reducing time to linkage to care. There is a vast need for research and interventions that target HIV-positive young adults in SSA which aim to improve their linkage and access to HIV care. The results of this study illustrate effective interventions in improving linkage to care and reducing time to linkage to care of young adults in SSA.
