Time-Series Forecasting Model for Evaluating Clinical Outcomes in Rural Clinics of Tanzania
type: item
description: Rural clinics in Tanzania often face challenges related to resource allocation and patient outcomes, necessitating robust methods for evaluating clinical performance. A time-series forecasting model was developed to predict clinical outcomes based on historical data from multiple rural clinics. The model incorporates ARIMA (AutoRegressive Integrated Moving Average) methodology, accounting for seasonal and trend components of the data. The model demonstrated a predictive accuracy with an R² value of 0.75 across all clinics evaluated, indicating moderate to strong correlation between forecasted outcomes and actual clinical measures. This study provides a validated method for monitoring and improving clinical performance in rural Tanzanian settings through timely forecasting. The findings suggest implementing the model as a routine tool for assessing clinic effectiveness and guiding resource allocation decisions. Rural clinics, Tanzania, clinical outcomes, time-series analysis, ARIMA Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Community-Led Waste Management Initiatives and Health Outcomes Among Vulnerable Populations in Kampala, Uganda
type: item
description: This study examines community-led waste management initiatives in Kampala, Uganda to assess their impact on health outcomes among vulnerable populations. Community surveys were conducted with a sample size of 300 participants, using a structured questionnaire designed to measure waste management practices and health status over two years. Data analysis revealed that the proportion of households participating in waste segregation increased from 25% pre-intervention to 60% post-intervention. This was statistically significant ($p < 0.01$). Community-led waste management initiatives have led to a substantial improvement in health outcomes among vulnerable populations, with a notable increase in sanitation practices. Further research should focus on the long-term effects of these interventions and explore ways to sustain them within community structures.

Grassroots Financial Inclusion
type: item
description: Despite growing recognition of community-based savings institutions across sub-Saharan Africa, the precise mechanisms through which Community Group Savings and Lending (CGSL) participation translates into measurable improvements in farming productivity remain underexplored — particularly in fragile, post-conflict contexts. This study examines the overarching influence of CGSL membership on rural agricultural development and technological adoption across three ecologically and socio-politically distinct states of South Sudan: Eastern Equatoria, Jonglei, and Lakes State. Drawing on a mixed-methods design that combined descriptive statistics, chi-square tests, and logistic regression analysis of primary data from 81 validated respondents (n=81; response rate 95%), alongside MAXQDA-facilitated thematic analysis of in-depth interviews, the study produces four integrated findings. First, chi-square testing confirms a statistically significant positive association between CGSL membership and agricultural productivity improvements across three indicators (χ²=15.92; p=0.0001). Second, logistic regression establishes that credit access through CGSLs significantly increases the probability of technology adoption (β=1.9459; p=0.026). Third, 100 per cent of respondents unanimously confirmed working capital scarcity as the primary investment barrier, establishing the exact developmental niche that CGSLs fill. Fourth, CGSL members demonstrate substantially higher rates of improved seed and fertiliser adoption compared to non-members, with member adoption rates exceeding non-member rates by 28–42 percentage points across technology categories. The study introduces the CGSL-Driven Agrarian Transformation Model (CDATM) — an original author-developed conceptual framework that maps the causal pathway from group membership through financial capital access, technology adoption, and market orientation to structural agrarian transformation. Findings confirm that CGSLs act as the primary ca…

Bayesian Hierarchical Model for Evaluating Public Health Surveillance System Reliability in Tanzania,
type: item
description: Public health surveillance systems are crucial for monitoring infectious diseases in developing countries like Tanzania. These systems rely on reports from healthcare providers and laboratories to detect outbreaks early. A Bayesian hierarchical model was applied to analyse surveillance data, accounting for variability at different levels (e.g., individual healthcare providers, regional laboratories). The model estimated that the reporting rate from healthcare providers varied by up to 25% across regions, with a mean of 80%, indicating moderate reliability. Bayesian hierarchical modelling provided insights into system variability and reliability, suggesting areas for improvement in data collection and transmission processes. Enhancements should focus on standardising reporting protocols and increasing training to ensure consistent and timely reports from healthcare providers. Public health surveillance, Bayesian hierarchical model, System Reliability, Tanzania Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Longitudinal Effects of Solar Irrigation Systems on Crop Yields in Northern Tanzania
type: item
description: Solar irrigation systems have been introduced to promote sustainable agricultural practices in arid regions, particularly in Tanzania's northern highlands where water scarcity is a significant constraint to crop productivity. A randomized controlled trial design was employed, with 20 farmers in each control (conventional drip irrigation) and intervention (solar-powered drip irrigation) groups. Data collection included pre- and post-intervention yield measurements using a linear regression model to account for potential confounders. Solar irrigation led to an average increase of 15% in maize yields compared to control conditions, with significant variation among individual farmers (e.g., one farmer saw a 20% increase). The solar irrigation systems demonstrated robust performance in enhancing crop productivity and were found to be economically viable over the long term. Further research should explore scalability of these systems, while policymakers could consider subsidies for farmers adopting such technologies to accelerate adoption in similar contexts. 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 Uganda
type: item
description: Public health surveillance systems in Uganda are essential for monitoring disease prevalence and guiding public health interventions. However, their effectiveness can vary significantly due to factors such as resource allocation, data quality, and reporting procedures. A mixed-methods approach will be employed, combining quantitative analysis of surveillance system data with qualitative interviews to understand operational challenges and strengths. The study will utilise logistic regression models to estimate the impact of surveillance systems on disease prevalence. Initial findings suggest that while the current surveillance systems detect a significant proportion (75%) of reported cases accurately, there is room for improvement in reporting speed and consistency across different regions. The quasi-experimental design provides robust evidence to inform policy decisions aimed at enhancing public health surveillance capabilities in Uganda. Immediate steps should include strengthening data collection protocols, training healthcare workers, and implementing standardised reporting procedures to improve the efficiency and effectiveness of surveillance systems. 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 are critical for monitoring and managing diseases in South Africa. These systems rely on various data sources and methodologies to ensure timely and accurate information is available. A comprehensive search strategy was employed across multiple databases including PubMed and Web of Science. Studies published between and were considered. Inclusion criteria included studies that evaluated the effectiveness of surveillance systems in South Africa, with a specific focus on adoption rates among healthcare providers. In our analysis, we identified a significant variation (p < 0.05) in the proportion of healthcare providers who reported adopting public health surveillance systems based on their perceived benefits and resource availability. The findings suggest that while there is variability in adoption rates across different regions of South Africa, certain factors such as training programmes and financial incentives significantly influence adoption rates. To enhance the effectiveness of public health surveillance systems, it is recommended that policymakers implement targeted training initiatives and provide adequate funding to support healthcare providers in adopting these systems. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Bayesian Hierarchical Model for Evaluating Cost-Effectiveness of Public Health Surveillance Systems in Tanzania
type: item
description: Public health surveillance systems are crucial for monitoring diseases and managing outbreaks effectively. In Tanzania, these systems face challenges in cost-effectiveness due to varying resource allocation across regions. A Bayesian hierarchical model was employed, incorporating data from multiple regions with varying levels of healthcare infrastructure. Model parameters were estimated using Markov Chain Monte Carlo methods, accounting for uncertainty through robust standard errors. The model revealed significant regional variations in the efficiency and cost-effectiveness of surveillance systems, with some rural areas underperforming compared to urban settings by a margin of at least 20% in terms of detection rates. This study provides evidence that supports targeted investments in infrastructure and training for underserved regions to improve overall system performance. Policy makers should prioritise investment in surveillance systems in rural areas, where the cost-effectiveness gap is most pronounced. Additionally, continuous monitoring and adaptive management strategies are recommended. Bayesian hierarchical model, public health surveillance, cost-effectiveness, Tanzania Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

description: Public health surveillance systems in Tanzania are crucial for monitoring clinical outcomes over time. However, the effectiveness of these systems can be improved through advanced analytical tools such as time-series forecasting models. A longitudinal study was conducted using data from the National Health Information System. A Vector Autoregression (VAR) model was employed to forecast trends in hospital-acquired infections, with uncertainty quantified through standard errors and confidence intervals. The VAR model demonstrated a significant predictive power for hospital-acquired infections, forecasting an increase of approximately 10% over the next year based on historical data. The study validates the efficacy of time-series forecasting models in enhancing public health surveillance systems. This novel method provides actionable insights to policymakers and healthcare providers. Policymakers should implement these forecasting tools to anticipate future clinical outcomes, enabling timely interventions and resource allocation. Vector Autoregression (VAR), Time-series Forecasting, Public Health Surveillance, Tanzania Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Cognitive Function Improvement Metrics Post-Mental Health Services Implementation Among Elderly in Urban Lagos, Nigeria
type: item
description: Urban Lagos, Nigeria faces significant challenges in mental health services provision for its elderly population, exacerbating existing cognitive decline issues. A longitudinal study design was employed with a sample size of 250 participants aged over 60 who received mental health services. Cognitive function assessments were conducted pre- and post-intervention using standardised tests. Memory scores improved by an average of 15% (95% CI: 7%, 23%) and problem-solving abilities increased by 8% (95% CI: 2%, 14%) among participants who received mental health services compared to the control group. The implementation of mental health services significantly enhances cognitive function in urban elderly populations, demonstrating a positive impact on their daily activities and quality of life. Further research should investigate long-term effects and potential cost-effectiveness analyses of such interventions. Policy makers are encouraged to integrate these findings into future mental health service frameworks for urban aging populations. Cognitive Function, Mental Health Services, Urban Elderly, Lagos, Nigeria Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
