Diagnosis-related group (DRG) analysis revealed inefficiencies in complicated cholecystectomies at Maricopa Medical Center. Identifying and correcting these issues, such as laparoscopic conversions, can improve patient care and reduce costs.

Area of Science:

  • Health Services Research
  • Hospital Administration
  • Medical Economics

Background:

  • A 1993 data review indicated Maricopa Medical Center had higher charges and longer length of stay (LOS) for diagnosis-related group (DRG) 195 (complicated cholecystectomies) compared to regional hospitals.
  • This suggested potential inefficiencies within the hospital's system for managing these procedures.

Purpose of the Study:

  • To identify the root causes of increased length of stay (LOS) and charges for diagnosis-related group (DRG) 195.
  • To determine if similar inefficiencies existed across other cholecystectomy DRGs.
  • To evaluate the utility of DRG delta analysis as a performance improvement tool.

Main Methods:

  • Analysis of twenty patient charts for DRG 195 to identify causes of inefficiency.

  • Comparative analysis of other cholecystectomy DRGs to identify systemic issues.
  • Utilized diagnosis-related group (DRG) delta analysis for performance evaluation.

    • Main Results:

    • Laparoscopic conversions were identified in 55% of DRG 195 cases, contributing to significant variations in charges and LOS.
    • Increased preoperative hospital days and operative times were also factors in prolonged LOS and higher costs.
    • A substantial portion (30%) of DRG 195 patients were over 70 years old, potentially impacting care complexity.
    • Similar inefficiencies were observed in other cholecystectomy DRGs, pointing to a hospital-wide problem.

    Conclusions:

    • Diagnosis-related group (DRG) delta analysis is an effective tool for identifying and addressing performance issues in healthcare settings.
    • Systematic identification and correction of identified problems lead to rapid improvements in quality of care and cost-efficiency.
    • Implementing these performance improvement models can enhance the competitiveness of teaching hospitals and meet accreditation standards for patient care.
