Physician profiling. How it can be misleading and what to do

Area of Science:

• Health Services Research
• Medical Economics
• Healthcare Management

Background:

• Hospitals face pressure to control costs, necessitating identification of high-cost physician practices.
• Diagnosis Related Groups (DRGs) are commonly used for physician cost comparison but have limitations.
• DRGs do not adequately account for patient illness severity, potentially leading to inaccurate assessments.

Purpose of the Study:

• To evaluate the effectiveness of the Computerized Severity Index (CSI) in profiling physician practice costs.
• To compare CSI-based physician profiling with traditional DRG-based methods.
• To identify genuinely high-cost physicians for targeted intervention.

Main Methods:

• Utilized the Computerized Severity Index (CSI) to measure patient illness severity.
• Developed physician practice profiles based on CSI-adjusted resource utilization.
• Compared CSI-based profiles with those generated using Diagnosis Related Groups (DRGs).

Main Results:

• CSI provides more accurate physician practice profiles by accounting for patient severity.
• DRG-based comparisons can lead to incorrect conclusions about physician costs.
• CSI-based profiling effectively identifies physicians with genuinely higher resource consumption.

Conclusions:

• The Computerized Severity Index (CSI) is a superior tool for assessing physician practice costs compared to DRGs.
• Accurate severity adjustment is crucial for meaningful physician cost profiling.
• CSI-based profiles can guide interventions to help physicians modify practice patterns and reduce costs.
