title: Hospital reported complications of laparoscopic cholecystectomy among Medicare and Medicaid patients.
abstract: The purpose of this study was to initiate a hospital-based case review of all laparoscopic cholecystectomies performed on Medicare and Medicaid patients in New York State in 1991 where there were one or more complications. Another purpose was to facilitate efforts by hospitals to monitor the performance of laparoscopic cholecystectomy through an educational process of data-sharing. There were 2,940 Medicare and 1,108 Medicaid cholecystectomies in New York State in 1991. Of these, 351 (11.9%) Medicare and 107 (9.7%) Medicaid patients were reported as having complications. The complication rate for Medicare patients was slightly lower than that observed (15.8%) in an epidemiologic study of Medicare patients in New York State who underwent laparoscopic cholecystectomy during the period January 1, 1990-June 30, 1991. Both of these observed rates for Medicare patients are higher than the mean 6.0% complication rate reported for open cholecystectomy in the literature. These increased rates may in part be due to age related risk factors present among Medicare patients. The absence of age related risk factors may also largely account for the lower laparoscopic cholecystectomy complication rate (9.7%) observed among Medicaid patients. The complication rate of 9.7% for Medicaid patients is similar to rates reported in other recent studies. The 11.9% complication rate for Medicare patients is higher than that reported in other recent studies. However, careful patient selection, the absence of age related risk factors, and greater surgical experience may account for the lower complication rates reported in some published series. Overall, the coding of complications was found to be accurate. The coding of laparoscopic cholecystectomy was found to be slightly flawed.(ABSTRACT TRUNCATED AT 250 WORDS)
