Impact Assessment of Food Security Interventions on Child Growth Rates in Ghanaian Regions
type: item
description: Food security interventions have been implemented in Ghanaian regions to address malnutrition among children. However, their long-term impact on child growth rates remains unclear. The study employed a mixed-methods approach, combining quantitative data from anthropometric measurements with qualitative interviews. Data were collected through community surveys and health facility records. A significant positive correlation was observed between the implementation of food security programmes and improved child growth rates, with approximately 15% higher mean height-for-age Z-scores in intervention areas compared to control regions. The findings suggest that sustained food security interventions can lead to substantial improvements in child growth outcomes. Future research should focus on replicating these findings across different socio-economic backgrounds and exploring the long-term sustainability of such programmes. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Mobile Health Check-ups in Rural South Africa
type: item
description: Rural areas in South Africa often face challenges in accessing healthcare services, particularly for chronic disease management. The analysis will aggregate data from multiple studies comparing mobile health check-up interventions with standard care controls, using standardised effect size measures and accounting for potential confounders such as socioeconomic status and geographical region. Mobile health check-ups showed a statistically significant improvement in blood pressure management (p < 0.05) compared to control groups after controlling for baseline differences. Mobile health check-up services appear effective in enhancing chronic disease management outcomes, particularly for hypertension among rural residents. Rural healthcare providers should integrate mobile health check-ups into their service delivery models as a cost-effective and accessible strategy for managing chronic diseases. 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 Ethiopia Using Time-Series Forecasting Models for Clinical Outcomes Assessment
type: item
description: Public health surveillance systems in Ethiopia are crucial for monitoring disease prevalence and guiding interventions. However, their effectiveness is often underappreciated due to limitations in data collection and analysis. The study employed a mixed-method approach, combining observational data from existing surveillance systems with predictive analytics. Time-series forecasting models were applied to historical clinical outcome data (e.g., incidence rates) to forecast future trends and evaluate system performance. A significant proportion (35%) of the model's predictions accurately reflected actual disease prevalence over a five-year period, indicating robustness in forecasting public health phenomena. The time-series forecasting models provided a reliable framework for assessing clinical outcomes within Ethiopia’s surveillance systems, offering valuable insights into system performance and potential areas for improvement. Enhanced data collection efforts should be prioritised to improve the accuracy of future forecasts. Additionally, cross-validation techniques could further validate model predictions across different geographic regions in Ethiopia. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

title: Methodological Evaluation of Public Health Surveillance Systems in South Africa
description: Public health surveillance systems in South Africa are crucial for monitoring diseases and guiding interventions. However, their effectiveness can be compromised by methodological issues that affect data accuracy and yield. A mixed-method approach combining quantitative analysis of existing surveillance data and qualitative interviews with stakeholders will be employed. The study will use statistical models such as logistic regression to assess the impact of proposed methodological changes. An initial analysis suggests that a modest increase in yield by up to 20% can be achieved through targeted improvements, particularly in areas prone to underreporting due to resource constraints and stigma. The quasi-experimental design provides robust evidence for the effectiveness of methodological enhancements, affirming their potential to improve data accuracy and public health outcomes. Public health authorities should prioritise implementing these improvements based on preliminary findings. Future research could explore scalability and cost-effectiveness in diverse settings. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Community-Based Diabetes Self-Management Programmes in Northern Ghana
type: item
description: Diabetes mellitus is a prevalent chronic condition in Northern Ghana, affecting both urban and rural populations disproportionately. Despite its importance, self-management of diabetes often relies on fragmented care provided by health workers with limited resources. A randomized controlled trial was conducted with 200 participants randomly assigned into an intervention group (receiving CBSM) and a control group (standard care). Data collection included pre- and post-intervention assessments using validated questionnaires for knowledge, adherence, and quality of life metrics. Statistical analysis employed a two-sample t-test to compare the means. Participants in the CBSM intervention showed significant improvement in diabetes-related knowledge compared to the control group (mean difference = 15 points; CI: [8, 23]; p < 0.001). The community-based diabetes self-management programme demonstrated positive effects on participants' knowledge levels and adherence to treatment protocols. Further studies should explore the sustainability of these programmes in diverse settings and assess their cost-effectiveness for wider implementation within Northern Ghana's health care system.

A systematic literature review was conducted using databases such as PubMed and Scopus. Studies published between and were included if they reported on the use of time-series forecasting models to assess clinical outcomes in rural Ghanaian clinics. One study employed an ARIMA model, finding a positive trend in patient recovery times with a $ARIMA(1,1,0)$ structure [mean recovery time: (95% CI) - (8.2 days, 11.3 days)]. The review highlights the potential of ARIMA models for improving clinical outcome assessments in rural Ghanaian settings. Further research should validate these findings and explore other forecasting methods that could be applied to diverse clinical outcomes.

Time-Series Forecasting Model for Clinical Outcomes in Senegalese District Hospitals Systems
type: item
description: District hospitals in Senegal are critical for healthcare delivery, particularly in underserved areas. However, their performance and potential improvements require robust evaluation methods. We employed a time-series forecasting model using historical data from selected district hospitals. The model was validated using cross-validation techniques and assessed for its predictive accuracy. Our analysis revealed that the proposed model accurately forecasted hospital readmission rates with an average error of ±5% over the study period. The time-series forecasting model demonstrated promising performance in predicting clinical outcomes at district hospitals in Senegal, offering a valuable tool for healthcare management and planning. Further research should be conducted to validate these findings across different regions and hospital types in Senegal. district hospitals, clinical outcomes, time-series forecasting, predictive analytics, Senegal Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Methodological Assessment of Public Health Surveillance Systems in Rwanda Using Difference-in-Differences for Clinical Outcome Evaluation
type: item
description: { "background": "Public health surveillance systems in Rwanda are critical for monitoring and managing infectious diseases such as malaria and tuberculosis (TB). However, their effectiveness varies over time due to factors like endemic prevalence, healthcare infrastructure improvements, and intervention strategies.", "purposeandobjectives": "To evaluate the methodological robustness of public health surveillance systems in Rwanda using a Difference-in-Differences (DiD) model for clinical outcome evaluation. The objective is to assess changes in TB incidence rates before and after implementing new diagnostic tools and treatment protocols.", "methodology": "Public health surveillance data from two distinct time periods were analysed: pre-intervention and post-intervention phases, spanning approximately five years each. A Difference-in-Differences model was applied to compare changes in TB incidence rates between intervention and non-intervention areas. The statistical model is represented as $Y{it} = \beta0 + \beta1 PreInterventioni + \beta2 Interventionj + \beta3 (PreInterventioni \times Interventionj) + u$ where $u$ captures unobserved heterogeneity.", "findings": "The DiD analysis revealed a significant reduction in TB incidence rates by 30% post-intervention, with robust standard errors indicating the model's reliability. This suggests that new diagnostic tools and treatment protocols had a substantial positive impact on clinical outcomes.", "conclusion": "The Difference-in-Differences method effectively highlights the effects of public health interventions on TB incidence rates in Rwanda, providing evidence for efficient resource allocation and policy development.", "recommendations": "Future studies should explore other infectious diseases and incorporate longitudinal data from multiple geographic regions to enhance the robustness of surveillance systems. Policy makers should consider implementing similar diagnostics and treatment protocols based on this study's…
