This study examined the effects of contract management on service delivery at Mulago National Referral Hospital (MNRH) in Central Uganda. Using a cross-sectional survey design, primary data were collected from 148 respondents comprising procurement officers, contract managers, clinical heads, and administrative staff. The study employed descriptive statistics, Pearson correlation analysis, and multiple linear regression to establish the relationship between contract management dimensions contract formulation, contract implementation, and contract monitoring and service delivery outcomes including availability of medical supplies, timeliness of care, and patient satisfaction. Findings revealed that contract management significantly and positively influences service delivery (β = 0.614, p < 0.01). Contract monitoring emerged as the strongest predictor (β = 0.382, p < 0.001), followed by contract implementation (β = 0.271, p < 0.01) and contract formulation (β = 0.198, p < 0.05). The study concludes that strengthening contract management systems is imperative for improving public health service delivery in Uganda's referral hospitals.
