title: Methodological Evaluation of Community Health Centre Systems in Uganda Using Multilevel Regression Analysis
description: Community health centres (CHCs) in Uganda play a crucial role in addressing healthcare needs within rural areas. Despite their importance, there is limited empirical evidence on how effectively these systems operate and whether they can be optimised for better service delivery. The review employs rigorous methodologies to select relevant studies based on predefined inclusion criteria. Quantitative data from these studies are analysed using multilevel regression models to assess the impact of various factors on CHCs' performance. Multilevel regression analyses reveal significant variance in service delivery quality across different levels, suggesting that interventions targeting both individual providers and community-level factors could enhance efficiency gains. For instance, provider-specific feedback loops show an average improvement of 15% in patient satisfaction scores after implementing these mechanisms. This review underscores the importance of adopting a multilevel approach to understand CHCs' performance dynamics and highlights specific strategies for enhancing their operational effectiveness. The findings suggest that policymakers should prioritise training programmes for providers at both the individual and managerial levels, alongside community engagement initiatives. This combination is likely to yield substantial improvements in service quality and patient outcomes. 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 Nigerian Community Health Centres Using Time-Series Models
type: item
description: Community health centers in Nigeria have been underutilized due to varying adoption rates of new health interventions. A time-series forecasting model was employed to analyse historical data from five randomly selected community health centers in Nigeria. The ARIMA (AutoRegressive Integrated Moving Average) model was used for its robustness and predictive capabilities. The ARIMA model indicated a significant trend with an estimated coefficient of adoption rate at 0.75 ± 0.12, suggesting that the community health centers can expect a moderate increase in adoption over time. This study provides evidence for the effectiveness of time-series forecasting models in predicting and improving adoption rates in Nigerian healthcare settings. Implementing these forecasts could guide policy decisions to enhance resource allocation and service delivery efficiency. Nigerian Community Health Centers, Adoption Rates, Time-Series Forecasting, ARIMA Model Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

School-Based Physical Activity Interventions and Childhood Obesity Reduction in Nairobi's Lower-Class Neighborhoods
type: item
description: Childhood obesity is a significant public health issue in Nairobi's lower-class neighborhoods, where physical activity levels are often low due to environmental and socioeconomic factors. A systematic review and meta-analysis approach was employed, including relevant studies from databases such as PubMed and Scopus. Studies were selected based on specific inclusion criteria related to school-based interventions and BMI changes. School-based physical activity interventions showed a significant mean BMI change of -0.5 kg/m² (95% CI: -1.0 to -0.05) among children in Nairobi's lower-class neighborhoods, indicating a modest but statistically meaningful reduction in obesity levels. The findings suggest that school-based physical activity interventions can be effective in reducing childhood obesity in Nairobi's lower-class neighborhoods, although the magnitude of effect was small and further research is needed to confirm these results. Given the effectiveness observed, it is recommended that schools in Nairobi's lower-class neighborhoods implement or expand existing physical activity programmes as part of their curriculum. Additionally, ongoing monitoring and evaluation should be conducted to assess the sustainability and impact of these interventions. 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 Measuring Clinical Outcomes in Public Health Surveillance Systems of Nigeria
type: item
description: Public health surveillance systems in Nigeria are essential for monitoring and managing clinical outcomes across various diseases. However, their effectiveness is often hampered by data quality issues such as missing or inconsistent information. The study employs a Bayesian hierarchical model to analyse clinical outcome data from multiple sources, including hospital records, community surveys, and laboratory tests. This approach allows for the integration of heterogeneous information with varying measurement scales. The analysis reveals that the Bayesian hierarchical model significantly improves accuracy in estimating disease prevalence and treatment outcomes compared to traditional methods, particularly when dealing with imprecise or incomplete data. The findings underscore the utility of Bayesian hierarchical models for enhancing the reliability of public health surveillance systems in Nigeria. This methodological evaluation provides a robust framework for improving clinical outcome measurements. Public health officials should consider implementing this model to enhance data quality and decision-making processes within their surveillance systems. Future research could explore its application across different diseases and geographic regions.

Modernization of Water Supply Systems and Its Impact on Childhood Diarrhea in Ethiopian Villages
type: item
description: Water supply systems in rural Ethiopian villages often lack modernization, leading to increased prevalence of childhood diarrhea. A systematic review and meta-analysis approach was employed using standardised databases for studies conducted between and . Studies were assessed based on quality, methodology, and outcomes related to childhood diarrhea reduction. The analysis identified a significant trend towards reduced childhood diarrhea incidence by 42% among villages with newly modernized water supply systems compared to those without (p < 0.05). Modernization of water supply systems in Ethiopian rural areas is associated with substantial reductions in childhood diarrhea. Implementing and sustaining modern water supply infrastructure should be prioritised for public health interventions targeting children under five years of age.

The Effectiveness of Community Health Volunteers in Cervical Cancer Screening Programmes in Northern Ghana
type: item
description: Cervical cancer is a significant health issue in Northern Ghana, where access to healthcare services can be limited due to geographical and socioeconomic factors. A longitudinal study design was employed with quantitative data collection methods including self-reported surveys, clinical examinations, and follow-up assessments over a two-year period. CHVs demonstrated an effective recall rate of 82% for cervical cancer screening appointments compared to the national average of 75%, indicating improved accessibility and patient compliance. The findings suggest that CHVs significantly enhance access to screening services, particularly in underserved rural areas of Northern Ghana. Further research should be conducted to assess the long-term impact on cervical cancer outcomes with a broader sample size. Training programmes for CHVs must also be improved to ensure consistent quality of care.

A Qualitative Validation of Wearable Sleep-Tracking Technology Against Polysomnography for Obstructive Sleep Apnoea in an Obese African Cohort at Aga Khan University Hospital, Nairobi
type: item
description: Obstructive sleep apnoea (OSA) is a significant but underdiagnosed comorbidity in obese populations across Africa. Polysomnography (PSG) is the diagnostic gold standard, but its limited availability necessitates investigation of accessible alternatives. Validation of consumer wearable sleep-tracking technology within African clinical contexts remains scarce. This study aimed to qualitatively validate a wearable sleep-tracking device against in-laboratory PSG for identifying OSA in an obese cohort. The objectives were to explore the device’s performance characteristics, its alignment with PSG-derived metrics, and to understand patient experiences and perceptions of both diagnostic methods. A qualitative, instrumental case study was conducted at the sleep laboratory of Aga Khan University Hospital, Nairobi. A purposively sampled cohort of obese patients (BMI ≥30 kg/m²) with suspected OSA underwent concurrent overnight PSG while wearing a commercially available wrist-worn sleep tracker. Data collection involved in-depth analysis of device-generated sleep reports compared to PSG scores, followed by semi-structured interviews with participants regarding their experience. Thematic analysis was employed for the interview data. Comparative analysis revealed a consistent trend of the wearable device underestimating sleep latency and overestimating total sleep time relative to PSG. A prominent theme from patient interviews was a strong preference for the wearable device’s comfort and convenience in a home setting, contrasted with the acknowledged clinical authority but reported intrusiveness of PSG equipment. The wearable device demonstrated notable discrepancies in specific sleep metrics compared to PSG, limiting its utility for precise diagnostic classification of OSA severity in this cohort. However, its high acceptability suggests potential utility as a screening tool to prompt formal referral. Further qualitative research should explore clinician perspectives on integrat…

A Systematic Review of Hospital-Based Light Exposure Systems on Circadian Rhythms and Inpatient Duration in Preterm Neonates
type: item
description: Preterm neonates in neonatal intensive care units (NICUs) are frequently exposed to abnormal light-dark cycles. This may disrupt the development of their circadian rhythms, potentially affecting physiological stability and extending hospitalisation. Research from African contexts, with distinct environmental and resource constraints, remains scarce. This systematic review aimed to synthesise evidence on the impact of hospital-based light exposure systems on circadian rhythm entrainment and the length of inpatient stay for preterm neonates. A key objective was to assess the applicability and reported outcomes of such interventions within African settings, using the Red Cross War Memorial Children's Hospital in Uganda as a focal point. A systematic search was performed across multiple electronic databases for relevant studies. Included studies investigated structured light exposure interventions in hospitalised preterm infants, measuring circadian parameters or length of stay. Study screening, selection, and data extraction were conducted by two independent reviewers. The quality of included studies was appraised using appropriate tools. The search identified a limited number of eligible studies, with very few conducted in African contexts. The available evidence, largely from high-income countries, suggests cycled light exposure may promote circadian rhythm development more effectively than continuous bright light or near-darkness. A prominent theme was the logistical challenge of implementing controlled light systems in resource-variable settings. No studies provided direct empirical data on length of stay specific to the Ugandan case study setting. While international evidence indicates potential benefits of cycled light for circadian entrainment in preterm neonates, there is a significant paucity of robust, context-specific research from African NICUs. The generalisability of findings from well-resourced settings to hospitals such as the Red Cross War Memorial Chi…
