title: Is academic managed care an oxymoron?
abstract: BACKGROUND
  A review of 1993 data on length of stay (LOS) and charges for diagnosis-related group (DRG) 195 (complicated cholecystectomies) showed that Maricopa Medical Center charged more and had longer LOS than all other area hospitals.
  
  
  METHODS
  Twenty DRG 195 charts were analyzed for the causes of the inefficiencies. The remaining cholecystectomy DRGs were similarly analyzed.
  
  
  RESULTS
  Analysis of the charts for DRG 195 showed that 55% of the patients had laparoscopic conversions. Charges and LOS varied significantly because of the conversions, increased preoperative hospital days and increased operative times. Moreover, 30% of patients were more than 70 years old. Comparisons of other cholecystectomy DRGs showed similar inefficiencies, indicating a hospital system's problem.
  
  
  CONCLUSIONS
  Diagnosis-related group delta analysis is a powerful performance improvement tool. Once problem areas are identified and corrected, monitoring prospective data produces rapid analysis of quality of care and cost improvements. The models can serve as a means for teaching hospitals to become more competitive and satisfy the Joint Commission on Accreditation of Healthcare Organizations requirements for patient-care improvements.
