The study is conducted over a two-year period (1989-1990) in all short-term general hospitals with 50 or more beds in Arizona.
We examine hospital discharge data for 43,625 women undergoing cesarean sections and vaginal deliveries without complications.
These data include physician identifiers that permit us to link patient information with information on physicians provided by the state medical association.
After controlling for patient factors, physician characteristics explain a significant amount of the variability in hospital charges and lenght of stay in the two maternity conditions.
Results also support hypotheses that efficiency is influenced by practice organization factors such as patient volume and managed care load.
Physicians with larger practices and a higher share of managed care patients appear to be more efficient.
The results suggest that health care reform efforts to develop physician-hospital networks and managed competition may promote greater parsimony in physicians'practice behavior.
