Methodological Evaluation of Public Health Surveillance Systems in South Africa Using Difference-in-Differences for Clinical Outcome Assessment
Public health surveillance systems are crucial for monitoring disease prevalence and health outcomes in South Africa. However, their effectiveness can be challenging to assess due to potential confounding factors. We employed a DiD regression analysis, accounting for temporal trends and geographical variations. The study utilised anonymized electronic health records from two provinces as our primary data source. Our findings indicate that the surveillance system in Province A showed a significant reduction of 15% in hospital admissions for respiratory infections compared to Province B over a five-year period. The DiD model provided robust evidence on the impact of public health interventions. Our study supports the use of this methodological approach for future evaluations. Future research should consider expanding the analysis to include more provinces and longer time periods to strengthen the findings' generalizability. public health surveillance, difference-in-differences, clinical outcomes, South Africa Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Time-Series Forecasting Model for Efficiency Gains in Community Health Centres in Tanzania
Community health centres in Tanzania have been established to improve access to healthcare services, yet their operational efficiency remains an area of concern. A time-series forecasting model was employed to analyse data from community health centre records in Tanzania. The model included ARIMA (AutoRegressive Integrated Moving Average) for predicting future performance based on historical trends. The ARIMA model showed a positive trend in efficiency gains over the period, with an estimated increase of 15% in service delivery effectiveness predicted by the end of the forecast horizon. This study provides evidence that time-series forecasting can be used effectively to assess and predict operational efficiencies in community health centres within Tanzania. Health policymakers should consider implementing similar models for continuous monitoring and improvement of service delivery efficiency. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
Impact of School-Based Sexual Health Education on Adolescent Behaviors in South African Schools,
Adolescent behaviors related to sexual health are influenced by various factors including school-based education programmes. A longitudinal study design was employed, collecting baseline and follow-up data from students attending secondary schools across South Africa. Data were analysed using linear mixed models to evaluate changes in behaviour over time. Comprehensive sexual health education led to significant reductions in unprotected sex (p = .03) and increases in contraceptive use (p < .01), with a notable increase in condom use from 25% at baseline to 40% at follow-up among sexually active students. The study provides evidence of the positive impact of consistent sexual health education on adolescent behaviors, particularly reducing risky sexual practices and increasing protective measures. Continued implementation and refinement of comprehensive school-based sexual health programmes are recommended to further enhance their efficacy in South African schools.

Evaluating the Implementation of a Drone-Delivered Blood Product System for Postpartum Haemorrhage in Remote Oromia, Ethiopia
Postpartum haemorrhage (PPH) remains a leading cause of maternal mortality in Ethiopia. Access to timely blood transfusion is a critical challenge in remote areas, creating a need for innovative delivery solutions. This mixed methods study evaluated the implementation of a drone-delivered blood product system for PPH in remote health centres of the Oromia region, Ethiopia. Its objectives were to assess the acceptability, feasibility, and fidelity of the system and to identify barriers and facilitators to its integration into routine emergency obstetric care. A convergent parallel mixed methods design was used. Quantitative data on drone delivery metrics, such as response times and success rates, were extracted from health facility records. Concurrently, qualitative data were collected through in-depth interviews and focus group discussions with healthcare workers, programme staff, and community representatives. Quantitative data were analysed descriptively, and qualitative data underwent thematic analysis. The system demonstrated high feasibility, with 94% of requested drone flights successfully completing delivery. The median drone transport time was 47 minutes, compared to a median of 4 hours for previous ground transport. Qualitative findings revealed strong acceptability among health workers, who reported increased confidence in managing PPH. Key implementation barriers included logistical disruptions during the rainy season and initial community apprehensions. The drone-delivered blood system was a feasible and acceptable intervention that substantially reduced transport times for essential blood products. Successful implementation depended on consistent technical support, proactive community engagement, and effective integration with existing emergency referral systems. To support scale-up and sustainability, recommendations include: investing in all-weather drone technology and supportive infrastructure; providing ongoing training and mentorship for health centre staff; and developing integrated national guidelines for drone-assisted emergency supply chains. postpartum haemorrhage, drone logistics, blood transfusion, implementation science, mixed methods, remote health services, Ethiopia.
