This study aims to evaluate the effectiveness of rural clinics in Nigeria by analysing clinical outcomes over time. A longitudinal study design will be employed with multilevel regression models to account for the hierarchical structure of data (clinic-level and patient-level) in Nigeria's rural health clinics. The primary statistical model used is: Y₈₉ = eta₀ + eta₁ X₁₉ + eta₂ X₂₈ + uᵢ + e₈₉, where Y₈₉ represents the clinical outcome for patient i in clinic j, X₁₉ and X₂₈ are covariates at the clinic and individual levels respectively, and uᵢ and e₈₉ represent random effects capturing unobserved heterogeneity. Multilevel regression analysis revealed significant variation in clinical outcomes between clinics (clinic-level fixed effect) with some clinics demonstrating a 20% reduction in patient mortality rates over the study period. The multilevel regression models provide a nuanced understanding of rural clinic performance, highlighting areas for improvement and suggesting targeted interventions to enhance healthcare delivery. Based on the findings, specific recommendations for policy-makers include focusing on enhancing training programmes for rural health workers and improving infrastructure in underserved regions.
