Abstract
The purpose of this study was to analyze the effects on clinical outcomes of regionalization for a high risk surgical procedure, pancreaticoduodenectomy (the Whipple procedure). Claims data were examined for all Medicare patients undergoing the procedure in New York State for the 4-year period 1991-1994. Outcomes were analyzed for two regional hospitals and for 115 other hospitals that performed the procedure. In-hospi tal mortality and length of stay were significantly less at the two high volume regional hospitals when compared with the remaining low volume hospitals. In-hospital mortality rates at all hospitals generally decreased as the number of procedures increased. The results of this study demonstrate that there is significant value in re gionalization for even relatively lower volume high risk surgical procedures.
