Factors affecting productive efficiency in primary care clinics

This study examines factors affecting the productive efficiency of primary care clinics. The empirical analysis uses a single-stage stochastic frontier regression model, in which factors affecting productive efficiency are specified as part of the inefficiency error component and estimated simultaneously with the production function. The study population includes primary care clinics in the US Military Health System from 1999 through 2003; the analytical data set is an unbalanced panel of 442 observations. The study's main results were that primary care clinics not associated with medical centres had significantly higher levels of productive efficiency than those associated with medical centres and that having proportionately more civilian staff (and thus less turnover) had a positive impact on productive efficiency. Due to their nature, these findings would be expected to also be applicable to the production of primary care in other settings. A key implication of the results is that improvements in productive efficiency should be a top priority, given the possibility for providing more primary care visits without increases in cost.
