DRGs: an overview of the issues.

Area of Science:

• Health economics
• Psychiatric care financing
• Healthcare policy

Background:

• Medicare implemented a prospective payment system (PPS) based on Diagnostic Related Groups (DRGs) in 1983.
• This system has demonstrated deficiencies specifically concerning psychiatric care.
• Psychiatric units in general hospitals received a temporary exemption due to advocacy by the American Psychiatric Association.

Purpose of the Study:

• To review the potential effects of a DRG-based payment system on psychiatric clinical practice.
• To discuss the shortcomings of the DRG system in accurately predicting service utilization for psychiatric care.
• To identify and suggest areas for future research in psychiatric care financing.

Main Methods:

• Review of existing literature and policy analysis regarding DRG-based prospective payment systems.
• Examination of problematic issues within current psychiatric care financing models.
• Discussion of clinical practice implications and service utilization prediction challenges.

Main Results:

• The DRG system presents several problematic issues for psychiatric care, including premature discharge, code manipulation, cost-shifting, and challenges in ensuring equitable patient access to services.
• The current DRG framework is inadequate for accurately predicting the utilization of psychiatric services.
• The impact of DRG-based payment on clinical practice requires careful consideration and review.

Conclusions:

• The prospective payment system based on Diagnostic Related Groups has inherent deficiencies for psychiatric care.
• Modifications or alternative financing systems for psychiatric care must address critical issues such as premature discharge, code manipulation, cost-shifting, and equitable patient access.
• Further research is necessary to develop effective and equitable financing models for psychiatric services.
