"background": "Rural clinic systems are critical for healthcare delivery in sub-Saharan Africa, yet robust methodological frameworks for evaluating their longitudinal performance are lacking. Existing assessments often rely on cross-sectional data, which fail to capture dynamic changes and unobserved heterogeneity. ", "purpose and objectives": "This study aims to develop and apply a panel-data econometric framework to evaluate the impact of systemic clinic factors on a range of clinical outcomes over a multi-decade period. The objective is to isolate the effects of resource inputs, staffing, and management practices from time-invariant clinic characteristics. ", "methodology": "We constructed a novel, longitudinal dataset from administrative records and health surveys. The primary analysis employed a two-way fixed effects model: Y{it = \0 + \1 Xit + \ + \ +, where Yit denotes clinical outcomes for clinic i in period t, Xit is a vector of time-varying covariates, \ represents clinic fixed effects, and \ₜ year fixed effects. Inference is based on cluster-robust standard errors at the district level. ", "findings": "A one-standard-deviation increase in the clinical officer-to-patient ratio was associated with a 7. 2% reduction in under-five mortality (95% CI: 4. 1% to 10. 3%). Conversely, drug stock-out frequency showed a non-linear relationship with antenatal care completion, with effects intensifying after a threshold of three occurrences per quarter. ", "conclusion": "The methodological approach confirms that panel-data techniques are essential for credible evaluation, revealing that staffing stability is a more potent driver of improved outcomes than episodic capital investment alone. ", "recommendations": "Policy should prioritise sustainable staffing models and integrated supply-chain logistics over isolated infrastructure projects. Future research should incorporate patient-level panel data within this clinic-level framework. ", "key words": "health systems evaluation, panel data, fixed
