Biosocial Analysis of the DREAMS Program in Tanzania

In Tanzania, the HIV epidemic is impacting many people throughout the country. However, this impact is not equally distributed among all people. Different areas in Tanzania suffer higher prevalence rates of HIV than others. In addition, females, especially adolescent girls and young women (AGYW), are at greater risk when it comes to HIV infection. These inequitable prevalence rates are caused by a number of factors, including but not limited to gender-based violence, lack of education, and involvement in transactional sex and sex work. In order to address HIV in Tanzania, U.S.-based groups including President's Emergency Plan for AIDS Relief (PEPFAR), the Centers for Disease Control and Prevention (CDC), and ICAP have designed and implemented the DREAMS program, which aims to protect AGYW from HIV infection via empowerment, education, and testing services. While this is a multi-faceted intervention that aims to protect women and address more than just the biological factors that spread disease, there are possible unintended consequences that can lead to harm.

An exploration of multi-level factors affecting routine linkage to HIV care in Zambia's PEPFAR-supported treatment program in the treat all era.

Multiple steps from HIV diagnosis to treatment initiation and confirmed engagement with the health system are required for people living with HIV to establish full linkage to care in the modern treat all era. We undertook a qualitative study to gain an in-depth understanding of the impeding and enabling factors at each step of this linkage pathway. In-depth interviews were conducted with fifty-eight people living with HIV recruited from ten routine HIV care settings supported by the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) in Lusaka, Zambia. Using a semi-structured interview guide informed by an established conceptual framework for linkage to care, questions explored the reasons behind late, missed, and early linkage into HIV treatment, as well as factors influencing the decision to silently transfer to a different clinic after an HIV diagnosis. We identified previously established and intersecting barriers of internal and external HIV-related stigma, concerns about ART side effects, substance use, uncertainties for the future, and a perceived lack of partner and social support that impeded linkage to care at every step of the linkage pathway. However, we also uncovered newer themes specific to the current test and treat era related to the rapidity of ART initiation and insufficient patient-centered post-test counseling that appeared to exacerbate these well-known barriers, including callous health workers and limited time to process a new HIV diagnosis before treatment. Long travel distance to the clinic where they were diagnosed was the most common reason for silently transferring to another clinic for treatment. On the other hand, individual resilience, quality counseling, patient-centered health workers, and a supportive and empathetic social network mitigated these barriers. These findings highlight potential areas for strengthening linkage to care and addressing early treatment interruption and silent transfer in the test and treat era in Zambia.

Prioritizing Mental Health within HIV and Tuberculosis Services in PEPFAR.

Underprioritization of mental health is a global problem and threatens the decades-long progress of the US President's Emergency Plan for AIDS Relief (PEPFAR) program. In recent years, mental health has become globally recognized as a part of universal healthcare, making this an opportune moment for the global community to integrate mental health services into routine programming. PEPFAR is well positioned to lead by example. We conceptualized 5 key strategies that might help serve as a framework to support mental health programming as part of PEPFAR's current 5-year strategic plan. PEPFAR and the global community have an opportunity to identify mental health service gaps and interweave global mental health priorities with actions to end the HIV and TB epidemics by 2030.

Tuberculosis Preventive Treatment Update - U.S. President's Emergency Plan for AIDS Relief, 36 Countries, 2016-2023.

Tuberculosis (TB) is the leading cause of death among persons with HIV. In 2022, an estimated 167,000 TB-related deaths occurred globally among persons with HIV. TB preventive treatment (TPT) helps prevent TB disease and is recommended for persons at high risk for developing TB, including those with HIV. TPT, when taken with antiretroviral treatment (ART), can reduce TB-attributable deaths among persons with HIV. In 2018, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) program committed to offer one course of TPT to all eligible clients receiving ART. This analysis describes trends in TPT initiation and completion among PEPFAR-supported programs in 36 countries in Africa, Central and South America, and Asia during fiscal years (FYs) 2017-2023. Overall, TPT initiation rates peaked in FY19, a possible sign of programmatic saturation. TPT initiation among clients who had been on ART <6 months reached 59%, and overall completion rates up to 87% were reported. Approximately 13 million persons with HIV have completed TPT since FY17, but widespread adoption of shorter regimens, patient-centered approaches, and electronic medical record systems might be needed to ensure full TPT coverage. Through PEPFAR's partnership with national HIV programs, TPT has become the standard of care for persons with HIV.

The impact ofshifts inPEPFAR funding policy onHIV services inEastern Uganda (2015-21).

Although donor transitions from HIV programmes are increasingly common in low-and middle-income countries, there are limited analyses of long-term impacts on HIV services. We examined the impact of changes in President's Emergency Plan for AIDS Relief (PEPFAR) funding policy on HIV services in Eastern Uganda between 2015 and 2021.We conducted a qualitative case study of two districts in Eastern Uganda (Luuka and Bulambuli), which were affected by shifts in PEPFAR funding policy. In-depth interviews were conducted with PEPFAR officials at national and sub-national levels (n = 46) as well as with district health officers (n = 8). Data were collected between May and November 2017 (Round 1) and February and June 2022 (Round 2). We identified four significant donor policy transition milestones: (1) between 2015 and 2017, site-level support was withdrawn from 241 facilities following the categorization of case study districts as having a 'low HIV burden'. Following the implementation of this policy, participants perceived a decline in the quality of HIV services and more frequent commodity stock-outs. (2) From 2018 to 2020, HIV clinic managers in transitioned districts reported drastic drops in investments in HIV programming, resulting in increased patient attrition, declining viral load suppression rates and increased reports of patient deaths. (3) District officials reported a resumption of site-level PEPFAR support in October 2020 with stringent targets to reverse declines in HIV indicators. However, PEPFAR declared less HIV-specific funding. (4) In December 2021, district health officers reported shifts by PEPFAR of routing aid away from international to local implementing partner organizations. We found that, unlike districts that retained PEPFAR support, the transitioned districts (Luuka and Bulambuli) fell behind the rest of the country in implementing changes to the national HIV treatment guidelines adopted between 2017 and 2020. Our study highlights the heavy dependence on PEPFAR and the need for increasing domestic financial responsibility for the national HIV response.

A community-based child health and parenting intervention to improve child HIV testing, health, and development in rural Lesotho (Early Morning Star): a cluster-randomised, controlled trial

When caregivers live in remote settings characterised by extreme poverty, poor access to health services, and high rates of HIV/AIDS, their caregiving ability and children's development might be compromised. We aimed to test the effectiveness of a community-based child health and parenting intervention to improve child HIV testing, health, and development in rural Lesotho. We implemented a matched cluster-randomised, controlled trial in the Mokhotlong district in northeastern Lesotho with 34 community clusters randomly assigned to intervention or wait-list control groups within a pair. Eligible clusters were villages with non-governmental organisation partner presence and an active preschool. Participants were caregiver-child dyads, where the child was 12-60 months old at baseline. The intervention consisted of eight group sessions delivered at informal preschools to all children in each village. Mobile health events were hosted for all intervention (n=17) and control (n=17) clusters, offering HIV testing and other health services to all community members. Primary outcomes were caregiver-reported child HIV testing, child language development, and child attention. Assessments were done at baseline, immediately post-intervention (3 months post-baseline), and 12 months post-intervention. We assessed child language by means of one caregiver-report measure (MacArthur-Bates Communicative Development Inventory [CDI]) and used two observational assessments of receptive language (the Mullen Scales of Early Learning receptive language subscale, and the Peabody Picture Vocabulary Test 4th edn). Child attention was assessed by means of the Early Childhood Vigilance Task. Assessors were masked to group assignment. Analysis was by intention to treat. This trial was registered with ISRCTN.com, ISRCTN16654287 and is completed. Between Aug 8, 2015, and Dec 10, 2017, 1040 children (531 intervention; 509 control) and their caregivers were enrolled in 34 clusters (17 intervention; 17 control). Compared with controls, the intervention group reported significantly higher child HIV testing at the 12-month follow-up (relative risk [RR] 1·46, 95% CI 1·29 to 1·65, p<0·0001), but not immediately post-intervention. The intervention group showed significantly higher child receptive language on the caregiver report (CDI) at immediate (effect size 3·79, 95% CI 0·78 to 6·79, p=0·028) but not at 12-month follow-up (effect size 2·96, 95% CI -0·10 to 5·98, p=0·056). There were no significant group differences for the direct assessments of receptive language. Child expressive language and child attention did not differ significantly between groups. Integrated child health and parenting interventions, delivered by trained and supervised lay health workers, can improve both child HIV testing and child development.

Evaluation of the impact of PEPFAR transition on retention in care in South Africa's Western Cape Province.

Research on the impact of the US President's Emergency Plan for AIDS Relief (PEPFAR) transition in South Africa (SA) in 2012 found varying results in retention in care (RIC) of people living with HIV (PLWH). To investigate the factors that impacted RIC during the PEPFAR transition in Western Cape Province, SA, in 2012. We used aggregate data from 61 facilities supported by four non-governmental organisations from 2007 to 2015. The main outcome was RIC 12 months after antiretroviral therapy initiation for two periods - during PEPFAR and post PEPFAR. We used adjusted quantile regression to estimate the effect of the PEPFAR pull-out on RIC. Regression models (50th quantile) for 12-month RIC showed a 4.0% (95% CI -7.7 - -0.4%) decline in RIC post-direct service. Facilities supported by Anova/Kheth'impilo fared worst post PEFPAR, with a decline in RIC of -4.9% (95% CI -8.8 - -1.0%), while TB, HIV/AIDS, Treatment Support, and Integrated Therapy (that'sit) fared best (3.6% increase in RIC; 95% CI: -0.2 - 7.3%). There was a decrease in RIC when comparing urban with rural areas (-7.8%; 95% CI -12.8 - -2.9%). City of Cape Town combined with Western Cape Government health facilities showed a substantial decrease (-6.1%; 95% CI -10.6 - -1.7%), while community health clinic (v. central day clinics) declined (-6.4; 95% CI -10.6 - -2.1%) in RIC. We observed no RIC difference by facility size and a slight increase when two or more human resources transitioned from PEPFAR to the government. When PEPFAR funding decreased in 2012, there was a decrease in RIC. To ensure the continuity of HIV care when a major funder withdraws sufficient and stable transition resources, investment in organisations that understand the local context, joint planning and co-ordination are required.

Analysis of economic and educational spillover effects in PEPFAR countries.

The United States President's Emergency Plan for AIDS Relief (PEPFAR) has been credited with saving millions lives and helping to change the trajectory of the global human immunodeficiency virus (HIV) epidemic. This study assesses whether PEPFAR has had impacts beyond health by examining changes in five economic and educational outcomes in PEPFAR countries: the gross domestic product (GDP) per capita growth rate; the share of girls and share of boys, respectively, who are out of school; and female and male employment rates. We constructed a panel data set for 157 low- and middle-income countries between 1990 and 2018 to estimate the macroeconomic impacts of PEPFAR. Our PEPFAR group included 90 countries that had received PEPFAR support over the period. Our comparison group included 67 low- and middle-income countries that had not received any PEPFAR support or had received minimal PEPFAR support (<$1M or <$.05 per capita) between 2004 and 2018. We used differences in differences (DID) methods to estimate the program impacts on the five economic and educational outcome measures. This study finds that PEPFAR is associated with increases in the GDP per capita growth rate and educational outcomes. In some models, we find that PEPFAR is associated with reductions in male and female employment. However, these effects appear to be due to trends in the comparison group countries rather than programmatic impacts of PEPFAR. We show that these impacts are most pronounced in COP countries receiving the highest levels of PEPFAR investment.

1036. Reporting of SARS-CoV-2 testing results among PEPFAR and non-PEPFAR countries in Sub-Saharan Africa during the first year of the COVID-19 pandemic

Abstract Background The U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) is the largest global health program dedicated to addressing a single disease. In its first ten years, PEPFAR invested one-fifth of country budgets on governance and health systems strengthening, including laboratories, surveillance networks, and long-term training of health care workers. In addition to furthering the HIV response and promoting the sustainability of health programs, it has been argued these investments built capacity to respond to novel public health threats such as SARS-CoV-2. Methods Testing data from 1/1/2020 through 2/17/2021 were downloaded from Our World in Data, an online database that collates information from national and international health agencies. These data were cross-referenced against publicly reported testing totals from Africa CDC and the World Health Organization. The data set did not include testing reported by governments through non-machine-readable formats such as social media or press releases. PEPFAR data were drawn from PEPFAR.gov. Results Of the 18 countries in sub-Saharan Africa (SSA) that reported testing data one year into the pandemic, 16 (88.9%) were PEPFAR countries (Table 1). Among PEPFAR countries in SSA, 16 of 27 countries (59.3%) reported SARS-CoV-2 tests performed, compared with 2 of 21 non-PEPFAR countries (9.5%, OR = 13.8). Among countries that reported testing, PEPFAR countries had a per-capita testing rate nearly 3 times that of non-PEPFAR countries (28.7 tests per 1,000 people vs. 9.6 tests per 1,000 people), suggesting greater testing capacity. PEPFAR countries reported higher COVID-19 case rates, likely due to increased testing, however this could also be due to regional differences in incidence (Table 2). Mean GDP per capita was 62% higher in non-PEPFAR SSA countries, making it unlikely that financial resources alone account for the observed differences.Figure 1.Countries that have received PEPFAR funding and countries that reported SARS-CoV-2 testing totals during the first year of the coronavirus pandemicTable 1.Reporting of SARS-CoV-2 testing in sub-Saharan Africa among PEPFAR and non-PEPFAR countries 1 year into the COVID-19 pandemicTable 2.COVID-19 indicators and characteristics of PEPFAR and non-PEPFAR countries in sub-Saharan Africa Conclusion PEPFAR countries in SSA were more likely than non-PEPFAR countries to report SARS-CoV-2 testing during the first year of the COVID-19 pandemic and also reported higher per-capita testing rates. This further supports anecdotal evidence that PEPFAR’s historical investments in health systems strengthened local capacity to respond to non-HIV public health emergencies such as COVID-19.

2068. Progress in the Infection Prevention and Control Monitoring System for the United States President’s Emergency Plan for AIDS Relief (PEPFAR) Programs and Supported Facilities

Abstract Background The U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) prioritizes infection prevention and control (IPC) activities in its 40,000 supported facilities in over 50 countries. PEPFAR’s 2015 quality assurance tool included four IPC indicators (tuberculosis IPC [TBIPC], waste management [WM], injection safety [IS], laboratory biosafety [LB]). In 2022, four new IPC indicators were added (IPC program [IP], environmental cleaning [EC], availability of personal protective equipment [PPE], medical device reprocessing [MD]). As of October 2022, PEPFAR programs are required to assess IPC indicators in 10% of facilities over the course of one year. We report quarter one data results. Methods Indicator data from October 1 - December 31, 2022 were analyzed. Scores were calculated based on compliance with 2-4 criteria each: green, yellow, and red represented good, fair, and poor compliance, respectively. Percentages of yellow and red scores were combined, to represent the percent of facilities requiring improvement. Results A total of 272 sites were assessed across 15 countries; each PEPFAR program selects the indicators to assess in each site. For existing indicators (TBIPC, WM, IS, LB), 16%, 34%, 22%, and 57% of sites assessed scored red or yellow, respectively; for indicators added in 2022 (IP, EC, PPE, MD), 74%, 67%, 64%, and 61% scored red or yellow, respectively (Figure). Specific gaps include: 63% of facilities lack adequate IPC leadership; ∼50% lack adequate environmental cleaning staff, protocols, and methods; 41% lack respirators; 30% lack device reprocessing protocols.Figure:Infection Prevention and Control (IPC) Indicator Scores from PEPFAR Panorama for Quarter 1 (October 1 – December 31, 2022) Conclusion Unknown IPC weaknesses were identified in PEPFAR supported facilities. PEPFAR requires that facilities with fair or poor compliance be reassessed within six months to monitor improvements. Strengthening IPC leadership is a priority. Improvement activities will require collaboration between facilities, implementing partners, and Ministries of Health (MOH). Future plans include increasing compliance with conducting required IPC indicator assessments; timely, data driven identification of gaps and advancements towards IPC standards; and developing guidance and resources to facilitate improvements. MOHs can leverage data to inform priorities and design context-specific interventions. Disclosures All Authors: No reported disclosures

Measuring training effectiveness of laboratory biosafety program offered at African Center for Integrated Laboratory Training in 22 President’s Emergency Plan for AIDS Relief supported countries (2008–2014)

IntroductionThe African Center for Integrated Laboratory Training (ACILT) in Johannesburg, South Africa offered a laboratory biosafety program to improve laboratory biosafety practices in 22 President’s Emergency Plan for AIDS Relief (PEPFAR) supported countries. This manuscript evaluates the transference of newly gained knowledge and skills to the participants’ place of employment for HIV and TB diagnostic laboratory programs. It also serves as a follow-on to a previously published manuscript that measured training effectiveness for all courses offered at ACILT.MethodsACILT offered 20 Laboratory Biosafety and Infrastructure courses (2008–2014), also referred as biosafety course/course comprising of 14 core laboratory safety elements to 402 participants from 22 countries. In 2015, participants received 22 e-questions divided into four categories: (1) Safety Policies, (2) Management’s Engagement, (3) Safety Programs and (4) Assessments of Safety Practices to determine retrospectively the training effectiveness of biosafety practices in their place of employment 6 months before and after attending their course. We used Kirkpatrick model to assess the transference of knowledge, skills and obstructive factors.Results20% (81/402) of the participants completed the e-questionnaire. The overall percentage of positive responses indicating implementation of new safety practices increased from 50% to 84%. Improvement occurred in all four categories after attending the course, with the greatest increases in Safety Policies (67–94%) and Safety Programs (43–91%). Creating a safety committee, allocating resources, and establishing a facility safety policy were important drivers for implementing and maintaining laboratory safety practices. In addition, accredited laboratories and countries with national safety regulations or policies had a higher percentage of improvements. The most reported challenges were inadequate funding and lack of management enforcement.ConclusionsPEPFAR and other partners’ investments in training institutions, such as ACILT, were effective in building sustainable country ownership to strengthen biosafety practices and were leveraged to combat zoonotic diseases and COVID-19. Although support continues at the national/regional level, a standardized, coordinated and continent-wide sustainable approach to offer a biosafety program-like ACILT is missing. Continuous offerings of biosafety programs similar to ACILT could contribute to sustainable strengthening of laboratory biosafety, QMS and pandemic preparedness.

Impact of HIV treat-all and complementary policies on ART linkage in 13 PEPFAR-supported African countries

BackgroundIn 2015, the World Health Organization recommended that all people living with HIV begin antiretroviral treatment (ART) regardless of immune status, a policy known as ‘Treat-All to end AIDS’, commonly referred to as Treat-All. Almost all low- and middle-income countries adopted this policy by 2019. This study describes how linkage to treatment of newly diagnosed persons changed between 2015 and 2018 and how complementary policies may have similarly increased linkage for 13 African countries. These countries adopted and implemented Treat-All policies between 2015 and 2018 and were supported by the U.S. Government’s President’s Emergency Plan for AIDS Relief (PEPFAR). The focuses of this research were to understand 1) linkage rates to ART initiation before and after the adoption of Treat-All in each country; 2) how Treat-All implementation differed across these countries; and 3) whether complementary policies (including same-day treatment initiation, task-shifting, reduced ART visits, and reduced ART pickups) implemented around the same time may have increased ART linkage.MethodsHIV testing and treatment data were collected by PEPFAR country programs in 13 African countries from 2015 to 2018. These countries were chosen based on the completeness of policy data and availability of program data during the study period. Program data were used to calculate proxy linkage rates. These rates were compared relative to the Treat All adoption period and the adoption of complementary policies.ResultsThe 13 countries experienced an average increase in ART linkage of 29.3% over the entire study period. In examining individual countries, all but two showed increases in linkage to treatment immediately after Treat All adoption. Across all countries, those that had adopted four or more complementary policies showed an average increased linkage of 39.8% compared to 13.9% in countries with fewer than four complementary policies.ConclusionsEleven of 13 country programs examined in this study demonstrated an increase in ART linkage after Treat-All policy adoption. Increases in linkage were associated with complementary policies. When exploring new public health policies, policymakers may consider which complementary policies might also help achieve the desired outcome of the public health policy.

Who Will Suffer Most if US AIDS Funding Ends.

The President's Emergency Plan for AIDS Relief (PEPFAR) is among the most successful US global health programs. It has moved HIV/AIDS from a certain death to a treatable disease. PEPFAR is now in danger of not being renewed. This perspective seeks to highlight the voice of perinatally HIV-infected Tanzanian youth.

Assessing sex differences in viral load suppression and reported deaths using routinely collected program data from PEPFAR-supported countries in sub-Saharan Africa

BackgroundIn sub-Saharan Africa, more women than men access HIV testing and treatment and may have better viral load suppression (VLS). We utilized routinely reported aggregated HIV program data from 21 sub-Saharan African countries to examine sex differences in VLS and death rates within antiretroviral therapy (ART) programs supported by the United States President's Emergency Plan for AIDS Relief (PEPFAR).MethodsWe included VLS and reported death data for persons aged 15 + years on ART from October–December 2020 disaggregated by sex and age for each subnational unit (SNU). We used linear mixed-model regression to estimate VLS proportion and negative binomial mixed-model regression to estimate the rates of death and death plus interruptions in treatment (IIT). All models were weighted for SNU-level ART population size and adjusted for sex, age, HIV/tuberculosis coinfection, country, and SNU; models for reported deaths and deaths plus IIT were also adjusted for SNU-level VLS.ResultsMean VLS proportion was higher among women than men (93.0% vs. 92.0%, p-value < 0.0001) and 50 + than 15–49 age group (93.7% vs. 91.2%, p-value < 0.0001). The mean rate of reported deaths was higher among men than women (2.37 vs. 1.51 per 1000 persons, p-value < 0.0001) and 50 + than 15–49 age group (2.39 vs. 1.50 per 1000, p-value < 0.0001); the mean rate of reported deaths plus IIT was higher among men (30.1 in men vs. 26.0 in women per 1000, p-value < 0.0001) and higher among 15–49 than 50 + age group (34.7 vs. 22.6 per 1000, p-value < 0.0001).ConclusionsThe mean rate of reported deaths was higher among men in most models despite adjusting for VLS. Further exploration into differences in care-seeking behaviors; coverage of screening, prophylaxis, and/or treatment of opportunistic infections; and more extensive testing options for men to include CD4 is recommended.

Retrospective longitudinal analysis of low-level viremia among HIV-1 infected adults on antiretroviral therapy in Kenya

HIV low-level viremia (LLV) (51-999 copies/mL) can progress to treatment failure and increase potential for drug resistance. We analyzed retrospective longitudinal data from people living with HIV (PLHIV) on antiretroviral therapy (ART) in Kenya to understand LLV prevalence and virologic outcomes. We calculated rates of virologic suppression (≤50 copies/mL), LLV (51-999 copies/mL), virologic non-suppression (≥1000 copies/mL), and virologic failure (≥2 consecutive virologic non-suppression results) among PLHIV aged 15 years and older who received at least 24 weeks of ART during 2015-2021. We analyzed risk for virologic non-suppression and virologic failure using time-dependent models (each viral load (VL) <1000 copies/mL used to predict the next VL). Of 793,902 patients with at least one VL, 18.5% had LLV (51-199 cp/mL 11.1%; 200-399 cp/mL 4.0%; and 400-999 cp/mL 3.4%) and 9.2% had virologic non-suppression at initial result. Among all VLs performed, 26.4% were LLV. Among patients with initial LLV, 13.3% and 2.4% progressed to virologic non-suppression and virologic failure, respectively. Compared to virologic suppression (≤50 copies/mL), LLV was associated with increased risk of virologic non-suppression (adjusted relative risk [aRR] 2.43) and virologic failure (aRR 3.86). Risk of virologic failure increased with LLV range (aRR 2.17 with 51-199 copies/mL, aRR 3.98 with 200-399 copies/mL and aRR 7.99 with 400-999 copies/mL). Compared to patients who never received dolutegravir (DTG), patients who initiated DTG had lower risk of virologic non-suppression (aRR 0.60) and virologic failure (aRR 0.51); similarly, patients who transitioned to DTG had lower risk of virologic non-suppression (aRR 0.58) and virologic failure (aRR 0.35) for the same LLV range. Approximately a quarter of patients experienced LLV and had increased risk of virologic non-suppression and failure. Lowering the threshold to define virologic suppression from <1000 to <50 copies/mL to allow for earlier interventions along with universal uptake of DTG may improve individual and program outcomes and progress towards achieving HIV epidemic control. No specific funding was received for the analysis. HIV program support was provided by the President's Emergency Plan for AIDS Relief (PEPFAR) through the United States Centers for Disease Control and Prevention (CDC).

Estimation of HIV prevalence and burden in Nigeria: a Bayesian predictive modelling study

The cost of population-based surveys is high and obtaining funding for a national population-based survey may take several years, with follow-up surveys taking up to five years. Survey-based prevalence estimates are prone to bias owing to survey non-participation, as not all individuals eligible to participate in a survey may be reached, and some of those who are contacted do not consent to HIV testing. This study describes how Bayesian statistical modeling may be used to estimate HIV prevalence at the state level in a reliable and timely manner. We analysed national HIV testing services (HTS) data for Nigeria from October 1, 2020, to September 30, 2021, to derive state-level HIV seropositivity rates. We used a Bayesian linear model with normal prior distribution and Markov Chain Monte Carlo approach to estimate HIV state-level prevalence for the 36 states+1 FCT in Nigeria. Our outcome variable was the HIV seropositivity rates and we adjusted for demographic, economic, biological, and societal covariates collected from the 2018 Nigeria HIV/AIDS Indicator and Impact Survey (NAIIS), 2018 Nigeria Demographic and Health Survey (NDHS) and 2016-17 Multiple Indicator Cluster Surveys (MICS). The estimated population of 15-49 years olds in each state was multiplied by estimates from the estimated prevalence to generate state-level HIV burden. Our estimated national HIV prevalence was 2.1% (95% CI: 1.5-2.7%) among adults aged 15-49 years in Nigeria, which corresponds to approximately 2 million people living with HIV, compared to previous national HIV prevalence estimates of 1.4% from the 2018 NAIIS and UNAIDS estimation and projection package PLHIV estimation of 1.8 million in 2022. Our modelled HIV prevalence in Nigeria varies by state, with Benue (5.7%, 95% CI: 5.0-6.3) having the highest prevalence, followed by Rivers (5.2%, 95% CI: 4.6-5.8%), Akwa Ibom (3.5%, 95% CI: 2.9-4.1%), Edo (3.4%, 95% CI: 2.9-4.0%) and Taraba (3.0%, 95% CI: 2.6-3.7%) placing fourth and fifth, respectively. Jigawa had the lowest HIV prevalence (0.3%), which was consistent with prior estimates. This model provides a comprehensive and flexible use of evidence to estimate state-level HIV seroprevalence for Nigeria using program data and adjusting for explanatory variables. Thus, investment in program data for HIV surveillance will provide reliable estimates for HIV sub-national monitoring and improve planning and interventions for epidemiologic control. This article was made possible by the support of the American people through the United States Agency for International Development (USAID) under the U.S. President's Emergency Plan for AIDS Relief (PEPFAR).

Population Estimates of HIV Risk Factors to Inform HIV Prevention Programming for Adolescent Girls and Young Women.

Violence Against Children and Youth Survey (VACS) data from seven countries were analyzed to estimate population-level eligibility for the President's Emergency Plan for AIDS Relief (PEPFAR) Determined, Resilient, Empowered, AIDS-Free, Mentored, and Safe (DREAMS) HIV prevention program for adolescent girls and young women (AGYW). The prevalence of overall eligibility and individual risk factors, including experiences of violence, social, and behavioral risks differ across countries and age groups. A large proportion of AGYW across all countries and age groups examined have at least one risk factor making them eligible for DREAMS. Experiencing multiple risks is also common, suggesting that researchers and programs could work together to identify combinations of risk factors that put AGYW at greatest risk of HIV acquisition, or that explain most new HIV infections, to more precisely target the most vulnerable AGYW. The VACS provides important data for such analyses to refine DREAMS and other youth programming.

Understanding Gender-Based Violence Service Delivery in CDC-Supported Health Facilities: 15 Sub-Saharan African Countries, 2017-2021.

Gender-based violence (GBV) is a complex issue deeply rooted in social structures, making its eradication challenging. GBV increases the risk of HIV transmission and is a barrier to HIV testing, care, and treatment. Quality clinical services for GBV, which includes the provision of HIV postexposure prophylaxis (PEP), vary, and service delivery data are lacking. We describe GBV clinical service delivery in 15 countries supported by the President's Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Centers for Disease Control and Prevention. Through a descriptive statistical analysis of PEPFAR Monitoring, Evaluation, and Reporting (MER) data, we found a 252% increase in individuals receiving GBV clinical services, from 158,691 in 2017 to 558,251 in 2021. PEP completion was lowest (15%) among 15-19-year-olds. Understanding GBV service delivery is important for policy makers, program managers, and providers to guide interventions to improve the quality of service delivery and contribute to HIV epidemic control.
