Comparative efficiency assessment of primary care service delivery models using data envelopment analysis.

This paper compares the relative productive efficiencies of four models of primary care service delivery using the data envelopment analysis method on 130 primary care practices in Ontario, Canada. A quality-controlled measure of output and two input scenarios are employed: one with full-time-equivalent labour inputs and the other with total expenditures. Regression analysis controls for the mix of patients in the practice population. Overall, we find that community health centres fare the worst when it comes to relative efficiency scores.
