Introduction: There is a shortage of individuals trained in using quantitative methods in biomedical research in sub-Saharan Africa (SSA). Improving public health in SSA requires new ways to promote quantitative knowledge and skills among faculty in biomedical research and better-integrated network systems of support.

Methods: We describe the development, implementation, and evaluation of an innovative faculty training and support program in SSA from December 2017-June 2020, using courses in monitoring and evaluation, data management, and complex surveys as prototypical examples. Indicators were selected to follow the 4 levels outlined in the Kirkpatrick evaluation model: reaction, learning, behavior, and results. We used survey data from faculty fellows and students and reported median change and interquartile ranges (IQR).

Results: The training program created an international community of 26 faculty members working collaboratively to lead the training of 3 quantitative methods courses. The program increased faculty members' knowledge of the course content (median increase 17 percentage points [IQR: 0, 20]). Faculty members, in turn, trained 380 students at institutions of higher education in 8 SSA countries (Botswana, Ethiopia, Ghana, Nigeria, Rwanda, South Africa, Tanzania, and Uganda).

Conclusion: The program relied on collaborative funding from participating institutions and focused on individual capacity-strengthening. In the future, the program will be scaled to include other emerging areas, such as data science, will integrate institutional support and feedback, and will move some of the training and mentoring activities to an online platform. Finally, to ensure that faculty have both improved confidence and improvement in competence, in future iterations, the program will include competency evaluation at the start and end and pair fellows who need additional training with those who excelled to co-teach.

Background: Despite increased antiretroviral therapy (ART) access in South Africa, HIV testing and ART initiation are suboptimal in hospital settings. Key gaps include in-hospital case finding, ART initiation support, and primary health care (PHC) facility linkage after discharge.

Intervention development and description: We identified weaknesses in hospital processes by comparing them with PHC HIV services and developed a quality improvement model for implementation in 5 Johannesburg hospitals. We introduced dedicated teams of HIV testing counselors for structured case finding and ART-trained nurses and linkage officers to provide in-hospital or post-discharge ART initiation and support to strengthen PHC facility linkage. Monitoring data (May 2020-March 2021) was used to measure initiation rates.

Lessons learned: Over 11 months, despite COVID-19 pandemic-related disruptions, our model achieved 74% (5,201/7,025) ART linkage within 28 days post-discharge and 87% (6,087/7,025) overall, including all initiations (i.e., all newly diagnosed, known not on ART and reinitiating individuals). The 2 highest-performing hospitals achieved 97% (2,096/2,170) linkage overall, demonstrating the potential of implementing this quality improvement model with fidelity. Over half (58%, 4,092/7,025) of patients initiated ART within 7 days, with 39% (2,748) initiating on the same day. Women and men achieved similar initiation rates (3,010/4,015, 75%; 2,186/3,003, 73%, respectively). Combining rapid (<7 days) in-hospital ART initiation with 28-day post-discharge follow-up supported high ART initiation rates. Using the model mitigated initiation gaps for men and older people, engaging stakeholders supported implementation, and using a team-based approach founded on clear roles and responsibilities improved service delivery.

Conclusion: This model achieved above-average ART linkage rates in a large hospitalized population. We recommend considering introducing this model or adaptations of it to hospitals across South Africa and similar settings where hospital-to-PHC ART service gaps are identified to optimize case finding, ART initiation, and post-discharge linkage support.

Introduction: Electronic decision-support systems (EDSSs) aim to improve the quality of antenatal care (ANC) through adherence to evidence-based guidelines. We assessed the potential of the mHealth integrated model of hypertension, diabetes, and ANC EDSS and the World Health Organization EDSS to improve the quality of ANC in primary-level health care facilities in Nepal.

Methods: From December 2021 to January 2023, we conducted a mixed-methods evaluation in 19 primary-level ANC facilities in Bagmati Province, Nepal. Implementation was from March 2022 to August 2022. We conducted a health facility survey, ANC clinical observations, longitudinal case studies and validation workshop, in-depth interviews, monitoring visits, research team debriefing meetings, health care provider attitude survey, and stakeholder engagement and feedback meetings. Results were integrated using concurrent triangulation to develop explanations about the EDSS implementation process and the effects observed.

Results: We identified 9 themes on implementation challenges that hindered the EDSS from generating the desired improvements to ANC quality. Facility readiness and provider confidence in using the EDSS were mixed. It was not always used or used as intended, and the approach to ANC provision did not change. EDSS inflexibility did not reflect how staff made decisions about pregnant women's needs or ensure that tests were done at the right time. There was mixed evidence that ANC staff believed that the EDSS benefited their work. The EDSS did not become fully integrated into existing health systems. Engagement of essential stakeholders fell short.

Conclusion: Different understandings of and inconsistent use of the EDSS highlighted the need for increased training and support periods, greater stakeholder engagement, and further integration into existing health systems. Our novel approach to integrating findings from multiple substudies offers uniquely valuable insights into the many factors needed for the successful implementation of an EDSS to improve the quality of ANC in Nepal.

Background: In 2022, 10% of an estimated 560,000 people living with HIV in Thailand were unaware of their HIV status. A well-established HIV program is a solid platform for integrating HIV self-testing (HST) as part of efforts to end AIDS. We analyzed how HST was integrated into the national HIV program and became a benefit package.

Policy adoption of hst: In 2015, the National AIDS Prevention and Alleviation Committee included HST as a strategy to end HIV/AIDS by 2030. This led to collaboration between the Department of Disease Control (DDC), Food and Drug Administration (FDA), and partner networks, including civil society organizations, to amend policy regulations, allowing HIV testing outside health care facilities and facilitating HST registration. By 2024, 4 HST commercial products were registered by the Thai FDA.

Program pilots: In 2020, the DDC launched pilot programs distributing HST kits through private pharmacies in Bangkok and online platforms. Preliminary findings showed feasibility in reaching key populations and adolescents. In 2023, HST was included in the Universal Health Coverage benefit package, providing free access to all citizens. Guidelines, e-learning, public awareness campaigns, and a reimbursement system of HST were developed and implemented. By September 2024, over 166,000 users had received HST kits.

Lessons learned: Leadership, scientific evidence, feasibility testing through pilots, regulatory adjustments, licensing, price negotiations by the National Health Security Office, and stakeholder and community engagement were key to the program's success. A nationwide distribution network through public and private health care facilities, including pharmacies, was a key enabling factor for HST delivery.

Conclusions: HST is an additional intervention to increase awareness of HIV status and a key component in Thailand's effort to end HIV/AIDS.

Introduction: As part of a laboratory strengthening program in Malawi to achieve and maintain International Organization for Standardization (ISO) 15189 accreditation, we intended to mentor selected HIV molecular laboratories to achieve this accreditation. Due to the COVID-19 pandemic, mentorship pivoted to a hybrid model using an Internet-based approach and on-site mentorships. We describe the implementation of this strategy, successes, and challenges.

Methods: We conducted weekly, 1-hour virtual mentorship sessions for the 5 initial laboratories (cohort 1) selected based on their Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) performance score of 3 or more stars. Laboratories presented updates and supporting documents electronically, and trainings were conducted virtually. In September 2020, when travel restrictions were relaxed, we initiated hybrid mentorships and audits for cohort 1 laboratories. The same hybrid approach was used to mentor 4 additional laboratories in cohort 2. We performed descriptive analysis, and the Wilcoxon signed-rank test was used to compare the training pre-and post-test scores.

Results: Between March 2020 and May 2023, the team completed a total of 54 virtual mentorship sessions and 20 on-site visits across 9 laboratories. Overall, the team conducted 8 training sessions for 35 laboratory quality officers. Median score improvement (pre-test vs. post-test scores) was observed across individual trainings and across cohorts (P<.01). At the end of cohort 1, 4 of 5 (80%) laboratories were accredited. One laboratory that did not reach accreditation joined cohort 2. At the end of the mentoring period, all 5 cohort 2 laboratories were accredited.

Conclusions: We demonstrated that using a hybrid mentorship model for accreditation was a successful strategy during the COVID-19 pandemic. For the first time in Malawi, this strategy resulted in accrediting 9 of the 10 HIV molecular laboratories in 3 years at a reduced cost. Continuous mentorship is key in the maintenance of accreditation.

Introduction: Timely access to emergency obstetric care (EmOC) remains a challenge in sub-Saharan Africa, influenced by poor health care utilization and rapid urbanization. Studies show poor maternal health outcomes in African cities, reflecting weak health systems. Understanding care-seeking pathways is key to improving service delivery and health outcomes. We examined self-reported care-seeking pathways among women with obstetric complications in Kampala City, Uganda.

Methods: In this cross-sectional survey, we collected sequential data from 433 women (15-49 years) from 9 health facilities in Kampala City. We developed typologies of common pathways to EmOC and descriptively analyzed key attributes, including median time spent at each step, comparing pathways across complications and participant characteristics. Provider utilization and service delivery performance issues were also assessed.

Results: Participants' average age was 26 years (standard deviation=6), with 55% (237/433) living outside Kampala. We identified 4 common pathways based on number and location of steps: pathways with 1 step, directly to a facility that provided required care (42%, 183/433); 2 steps, mostly including direct facility referrals (40%, 171/433); 3 steps (14%, 62/433); and 4 or more steps (4%, 17/433). Comprehensive EmOC facilities referred elsewhere 43% (79/184) of women who initially sought care in these facilities. Peripheral facilities referred 65% of women directly to the national referral hospital. A majority (60%, 34/57) of referred women returned home before reaching the final care facility.

Conclusions: Our findings suggest that care pathways of women with obstetric complications in Kampala often involve at least 2 formal providers and reflect possible inefficiencies in the referral process, including potential delays and unnecessary steps. Efforts to strengthen urban health and referral systems should adopt multidisciplinary and integrated approaches, supported by clear policies and structures that facilitate effective interfacility and interdistrict care coordination. This should include streamlined care/referral pathways and equitable emergency transportation systems.
