{ "background": "Emergency care systems in sub-Saharan Africa are underdeveloped, with limited evidence on the impact of formalising these services on patient outcomes. Robust evaluations of health system interventions in low-resource settings are methodologically challenging.", "purpose and objectives": "This study aimed to quantify the causal effect of implementing standardised emergency care units (ECUs) on clinical outcomes in a low-resource health system, using a quasi-experimental design.", "methodology": "We employed a difference-in-differences (DiD) model, analysing longitudinal patient-level data from intervention and control hospitals. The primary specification was $Y{it} = \\alpha + \\beta (Treati \\times Postt) + \\gammai + \\deltat + \\epsilon{it}$, where $Y_{it}$ is the mortality outcome. Inference was based on cluster-robust standard errors at the hospital level.", "findings": "ECU implementation was associated with a statistically significant 4.8 percentage point reduction in all-cause 24-hour mortality (95% CI: -7.1 to -2.5). The reduction was concentrated among non-trauma cases, with no significant effect observed for trauma-related admissions.", "conclusion": The establishment of formal emergency care units significantly improved early mortality outcomes for non-trauma patients, demonstrating the value of targeted systemic strengthening.", "recommendations": "Health policy should prioritise investment in standardised emergency care systems, with initial focus on medical (non-trauma) pathways. Future scale-up should be accompanied by embedded longitudinal evaluation.", "key words": "Emergency medical services, health systems evaluation, quasi-experimental design, sub-Saharan Africa, clinical outcomes, health policy", "contribution statement": "This study provides the first application of a difference-in-differences framework to evaluate a national emergency care system rollout in Africa, generating causal evidence for health system planning." } ``` Background Emergency care systems in sub-Saharan Africa are underdeveloped, with limited evidence on the impact of formal
