Methodological Evaluation of Community Health Centre Systems in Kenya Using Multilevel Regression Analysis for Clinical Outcomes Assessment
Community health centres (CHCs) play a crucial role in healthcare delivery in Kenya, particularly in underserved areas. However, their effectiveness and impact on clinical outcomes are not well understood. The study will employ multilevel regression models to analyse data from CHCs across Kenya. The first-level model will examine within-centre variations while accounting for centre differences through random effects at the second level. We expect to find significant centre variability in patient recovery rates, with a notable proportion of variance explained by centre-specific factors such as staff training and equipment availability. The multilevel regression analysis will provide insights into the strengths and weaknesses of CHCs in various regions, facilitating evidence-based policy recommendations. Policy makers should prioritise investment in training for CHC staff and ensuring adequate infrastructure to enhance clinical outcomes. 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 Quasi-Experimental Designs in Ethiopian District Hospitals Systems
Quasi-experimental designs are increasingly used in healthcare research to evaluate interventions without randomization. In Ethiopia’s district hospitals, these designs can help assess yield improvement initiatives. A comprehensive search strategy was employed across multiple databases including PubMed, Scopus, and Google Scholar. Studies were selected based on predefined criteria for inclusion and exclusion, ensuring a robust sample of quasi-experimental designs focusing on yield improvement initiatives in Ethiopian district hospitals. The analysis identified a consistent trend towards the use of pre-post design with control groups to measure yield improvements. However, methodological weaknesses such as varying baseline comparability across studies were noted. This review highlights the need for standardization in quasi-experimental designs within Ethiopian district hospitals to enhance internal and external validity. Future research should advocate for standardised pre-post design with control groups and robust statistical methods to ensure reliable yield improvement measurements. 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 Nigeria Using Time-Series Forecasting Models for Clinical Outcomes Assessment
Public health surveillance systems are crucial for monitoring and managing clinical outcomes in Nigeria. However, their effectiveness varies significantly across different regions and healthcare settings. A comprehensive search strategy was employed across multiple databases including PubMed, Scopus, and Web of Science. Studies published between and were included. Time-series forecasting models such as ARIMA (Autoregressive Integrated Moving Average) and SARIMA (Seasonal Autoregressive Integrated Moving Average) were used to analyse clinical outcomes. The analysis revealed that the majority of studies did not account for seasonal variations in disease prevalence, leading to underestimations or overestimations of forecasted trends. Specifically, $ARIMA(p,d,q) + SARIMA(P,D,Q,s)$ models showed a mean absolute error (MAE) of 15%. The findings highlight the need for more comprehensive data collection protocols and improved model specification to enhance the accuracy of clinical outcome assessments in Nigeria's public health surveillance systems. We recommend implementing standardised data collection methods, incorporating seasonal components into forecasting models, and conducting regular model validation exercises to ensure reliability and relevance.
