Prospects for using DRGs in Swedish hospitals

Area of Science:

• Health economics
• Healthcare management
• Medical informatics

Background:

• Swedish healthcare costs decreased as a share of GDP (9.7% to 9.1%) between 1982-1986.
• Traditional productivity measures in Swedish healthcare may not adequately reflect advancements in medical technology, case-mix, or quality.
• There is significant interest in Sweden regarding improved methods for healthcare planning, budgeting, and follow-up.

Purpose of the Study:

• To evaluate the feasibility and adequacy of using Diagnosis Related Groups (DRGs) in the Swedish healthcare system.
• To assess DRGs for potential application in planning, budgeting, and follow-up processes.
• To determine if DRGs can provide a more accurate measure of healthcare productivity and resource allocation.

Main Methods:

• A project was initiated by the Swedish Planning and Rationalization Institute of Health and Social Services (Spri).
• The study utilized over 500,000 patient discharges from 6 Swedish counties.
• Data from Swedish discharge abstracts were compared with a US database for DRG analysis, focusing on length of stay and diagnosis coding.

Main Results:

• Swedish and American lengths of stay correlated well (r = 0.83) in a comparison of DRG data.
• A notable difference was observed in the average number of diagnosis codes per patient (1.4 in Sweden vs. 2.8 in the US).
• This discrepancy suggests potential systematic differences in coding practices for complications and comorbidities between the two countries.

Conclusions:

• Diagnosis Related Groups (DRGs) show potential for use in the Swedish healthcare system for planning and budgeting.
• Further investigation into coding practices is warranted to ensure accurate DRG assignment and comparison.
• The study highlights the need for updated productivity measures that account for evolving healthcare complexities.
