Introduction: Gender-based violence (GBV) not only poses significant public health and human rights challenges but is also closely associated with HIV. GBV acts as a barrier to HIV prevention, testing, and treatment adherence, and fear of GBV inhibits disclosure of HIV status to sexual partners. In Malawi, where both GBV and HIV prevalence is high, integrating GBV services into HIV care is crucial. We describe the integration of GBV services into Lighthouse Trust's HIV testing and treatment clinics in Malawi, including screening, documentation, intervention implementation, outcomes, and lessons learned.

Methods: We conducted a retrospective analysis from January 2020 to June 2024. Data on cases identified, post-GBV services, and perpetrator demographics were collected from the GBV register. We used descriptive statistics to describe the intervention outcomes.

Results: We documented 9,045 reported GBV cases among males and females from January 2020 to June 2024. Adolescent girls aged 10-19 years constituted a significant proportion of survivors. Psychosocial services were the most common type of service that was offered to GBV survivors (25%), followed by HIV testing (19%) and sexually transmitted infection screening (18%). Perpetrators were mostly known to survivors.

Conclusion: We successfully integrated GBV services into the Lighthouse Trust HIV clinics in close collaboration with the one-stop centers in Malawi. Training health care providers enhanced support for GBV survivors, with a focus on increasing awareness, especially for children and adolescents. Recommended actions include improving access to GBV services, enhancing documentation, and promoting multi-sectoral collaboration to ensure comprehensive care aimed at creating a safer, more dignified health care environment for all, particularly GBV survivors.

The application of human-centered design (HCD) is growing in global health, given its potential to generate innovative solutions to entrenched health problems by prioritizing human perspectives, needs, and desires. To address gaps in consolidated evidence on prior programs, we conducted a review of studies that applied a comprehensive HCD approach in low- and middle-income countries. A total of 535 articles were initially identified. Based on the inclusion and exclusion criteria, 22 articles were included. Most studies were conducted in sub-Saharan Africa and used qualitative or mixed methods throughout the HCD work. In the "discover and define" phase, user personas, journey maps, and interviews were commonly used to empathize with end users and key stakeholders. Studies used various strategies in the "ideation" phase, including idea generation based on feasibility and resource constraints. In the "testing" phase, low-fidelity prototypes were tested to obtain feedback from end users and stakeholders, enabling quick and cost-effective refinements. Prototype iterations occurred twice in most studies, but information about when iterations ceased was limited. Evaluations of design outcomes and health impacts were lacking. Studies cited multidisciplinary approaches, flexible methodology, and a sense of ownership among users and communities as strengths of HCD. Contrastingly, challenges in consistent participant engagement and limited scientific rigor were reported as weaknesses. Elements that enhanced program reporting included clear descriptions of HCD as cyclical, stakeholder maps (empathy tools), visual materials on design activities and prototypes, and transparency in failures. We recommend strengthening capacity among those applying HCD to optimize the effectiveness of the approach for global health. Although HCD is not inherently intended to serve as a rigorous research method, data triangulation and proper evaluations may ensure its usability as evidence in health research when appropriate. Also, a thorough reporting of design phases and providing detailed rationale behind design decisions can advance future HCD literature.

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.

Background: In San Lucas Tolimán (SLT), Guatemala, a rural municipality with a large Indigenous population, women seeking cervical cancer screening face many barriers. We describe the process from design to implementation of a culturally appropriate and accessible cervical cancer screening and treatment pilot program for women aged 30-49 years.

Methods: After conducting a community needs assessment, we trained community health workers (CHWs) on basic cervical cancer pathophysiology and human papillomavirus (HPV) self-swab kit use. CHWs provided educational seminars and enrolled interested, eligible women in a mobile health application. Women collected samples at home and returned completed kits to CHWs, who sent the kits to a partner lab. Women who were positive for HPV received follow-up care at the local hospital, where physicians had received training in visual inspection with acetic acid (VIA) with same-day cryotherapy or thermocoagulation. Women with advanced lesions received access to care from gynecologists free of cost.

Results: Between February and November 2023, of the 230 women eligible to participate in the program, 132 completed HPV self-swabs and received results, and 34 received positive HPV tests (25.76% prevalence). Sixty-seven women had VIA exams as their first screening. Women who received VIA exams had an overall positivity rate of 24.47% (23/94). Twenty-three women received treatment: cryotherapy (n=8), thermocoagulation (n=7), or loop electrosurgical excision procedure (n=8). SLT had higher HPV-positivity rates than nearby Escuintla (21.6%; P=.29) and significantly higher than Santiago Atitlán (17.4% HPV+; P=.02).

Conclusion: Our screening program found significantly higher HPV-positivity rates in SLT than in previous Guatemalan studies. Our research reinforces that adequately treating cervical cancer in Guatemala requires accompaniment during care and economic support to make care affordable or free. Based on our pilot program, organizations worldwide can further invest in culturally sensitive cervical cancer screening and treatment.

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: The majority of neonatal deaths occur in low- and middle-income countries, most often due to perinatal events, prematurity, and/or infection. Reprocessing of neonatal resuscitation equipment is vital for ensuring the availability of clean equipment and preventing transmission of infection to a newborn. Staff at Tenwek Hospital, a tertiary referral hospital in rural Kenya, identified reprocessing medical equipment as a gap in improving neonatal care. We sought to implement steam-based high-level disinfection (HLD) for reprocessing neonatal resuscitation equipment in the labor and delivery ward of Tenwek Hospital.

Needs assessment: Before implementation, a needs assessment was conducted to identify existing facilitators and barriers to reprocessing through semistructured interviews with key stakeholders at the hospital (N=12) and identify gaps in the hospital's existing reprocessing procedures. A chemical, chlorine-based method of disinfection was used for neonatal resuscitation equipment in the ward. We conducted baseline bacterial burden of neonatal resuscitation equipment before clinical use, after clinical use, and after reprocessing. There was not a significant decrease in bacterial burden after reprocessing.

Implementation: After implementing a new steam-based HLD process, we conducted bacterial burden testing, which showed a reduction. However, staff preferences and implementation challenges compelled us to modify our original plan and instead implement optimized chemical HLD using chlorine. Although testing showed improved bacterial burden from baseline, in our small number of samples, bacterial burden testing after implementing the optimized chemical HLD process did not differ significantly compared to steam-based HLD.

Conclusions: Optimal chemical HLD was felt to be feasible and sustainable in the local setting. Reprocessing methods should be designed for unique challenges in low-resource settings.
