Ugandan district hospitals play a crucial role in healthcare delivery, but their performance metrics such as patient yield improvement are often poorly documented and forecasted. Time-series analysis was employed to model yield improvements over time. The Box-Jenkins methodology was used with an ARIMA (AutoRegressive Integrated Moving Average) model for forecasting. The ARIMA(2,1,0) model provided a forecast direction of increase in patient yield improvement by approximately 5% within the next year. Time-series models effectively predict yield improvements at Ugandan district hospitals, offering a robust methodological evaluation. Further research should explore integrating these models into hospital management systems for better resource allocation and planning.
