Methodological Evaluation of Public Health Surveillance Systems in Ethiopia
Public health surveillance systems are crucial for monitoring diseases and managing public health crises in Ethiopia. A difference-in-differences (DiD) model was employed to assess changes in disease prevalence before and after implementing surveillance enhancements. The study utilised data from two time periods: pre-implementation and post-implementation phases. The DiD analysis revealed a significant reduction in the incidence of measles by 30% within one year of enhanced surveillance, with a confidence interval around the effect estimate indicating variability due to sampling error. Enhanced public health surveillance systems have demonstrated cost-effectiveness and potential for reducing disease prevalence in Ethiopia. Further research should be conducted to validate these findings across different diseases and regions within Ethiopia. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Evaluating District Hospitals' Systems in Nigeria Through Multilevel Regression Analysis for Cost-Effectiveness Assessment
Nigeria faces significant challenges in healthcare delivery, particularly in district hospitals which serve as critical points of care for rural populations. A multilevel regression analysis was employed, considering both individual patient outcomes and system-level variables such as staffing levels and infrastructure quality. Data were collected from 20 district hospitals across Nigeria over two years. The analysis revealed that a 1% increase in the number of trained healthcare workers led to an average reduction in outpatient costs by 3.5%, indicating a significant cost-saving potential within the system. This study highlights the importance of workforce development and infrastructure improvements for enhancing the cost-effectiveness of district hospital systems, providing practical insights for policymakers and healthcare administrators. Policymakers should prioritise investments in training programmes and upgrading facilities to align with best practices identified through this research. District hospitals are encouraged to adopt standardised protocols for better resource management. district hospitals, multilevel regression analysis, cost-effectiveness, Nigeria Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
Methodological Evaluation of District Hospitals Systems in Ethiopia
District hospitals in Ethiopia face challenges in delivering efficient healthcare services. A mixed-methods approach combining quantitative data analysis with qualitative interviews was employed to assess system performance over two years. District hospitals showed an average improvement in patient throughput by 15% after implementing targeted efficiency measures, although variability existed across different regions.

Forecasting Risk Reduction in Senegalese District Hospitals
Recent studies have highlighted significant challenges in risk management within Senegalese district hospitals, particularly regarding patient outcomes and resource allocation. A comprehensive time-series analysis was conducted using historical hospital data from three districts, focusing on patient admissions, bed turnover rates, and financial expenditure patterns over a five-year period. The model utilised an ARIMA (AutoRegressive Integrated Moving Average) approach to forecast future trends with robust standard errors provided. The forecasting model demonstrated an accuracy rate of 85% in predicting hospital resource needs, highlighting the need for proactive risk reduction strategies such as staffing adjustments and inventory management improvements. This study validates the utility of time-series forecasting models in enhancing district hospitals' operational efficiency by providing actionable insights into potential risks and enabling better resource allocation.

Bayesian Hierarchical Model Assessment of District Hospitals System Reliability in South Africa,
This study evaluates the reliability of district hospitals in South Africa by applying a Bayesian hierarchical model. A Bayesian hierarchical model was employed to analyse the performance of district hospitals across multiple sites. The model accounts for spatial variability and heterogeneity in hospital systems. The analysis revealed that the average system reliability varied significantly between districts, with some areas showing a decline over time. Bayesian hierarchical models provide a robust framework to understand and quantify system performance at district levels, enhancing decision-making for healthcare resource allocation. District health authorities should prioritise interventions in regions identified as having lower reliability to improve overall service delivery. district hospitals, Bayesian hierarchical model, system reliability, 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.

Methodological Evaluation of Public Health Surveillance Systems in Senegal Using Difference-in-Differences for Risk Reduction Measurement
Public health surveillance systems are crucial for monitoring diseases and guiding interventions in Senegal and other countries. However, their effectiveness can vary over time due to changes in healthcare policies or resource allocation. We employed a Difference-in-Differences approach to analyse the impact of policy changes on disease surveillance metrics. Data from two consecutive years were used to construct synthetic control groups, ensuring comparability between regions within Senegal and across countries for robust DID estimation. The analysis revealed that after implementing new policies, there was a statistically significant reduction in reported cases of malaria (p < 0.05) compared to baseline levels, indicating the effectiveness of these measures in reducing disease incidence. This study provides evidence supporting the efficacy of recent policy interventions aimed at improving public health surveillance systems in Senegal. The findings suggest that timely and targeted policy changes can lead to measurable reductions in reported disease cases. Based on our results, it is recommended that ongoing monitoring should continue for these policies and further research should be conducted to explore other potential areas where similar improvements could be achieved. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Forecasting Adoption Rates in Ugandan Community Health Centres
Community health centres in Uganda have been established to improve access to healthcare services across rural areas where facilities are scarce. A time-series analysis was conducted on data from five Ugandan community health centres, employing an ARIMA (AutoRegressive Integrated Moving Average) model to forecast adoption rates over a six-month period. The ARIMA(1,1,0) model showed that the average monthly adoption rate fluctuated by ±2% around its mean value, indicating moderate variability in service uptake across centres. The time-series forecasting approach provided insights into the potential factors affecting community health centre utilization and can inform future policy interventions aimed at increasing their effectiveness. Further research should explore non-technical barriers to adoption such as cultural norms or financial constraints, alongside improving data collection methods for more accurate forecasting. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
