Psychiatry under prospective payment: experience in the first year

Area of Science:

• Health economics
• Psychiatric care delivery
• Healthcare policy

Background:

• The implementation of the prospective payment system (PPS) in 1984 significantly altered hospital reimbursement structures.
• Medicare psychiatric patients in general hospitals represent a key demographic affected by these policy changes.

Purpose of the Study:

• To analyze the impact of the prospective payment system (PPS) on resource utilization for Medicare psychiatric patients.
• To compare changes in length of stay and charges per discharge before and after PPS implementation.

Main Methods:

• Retrospective analysis of Medicare patient data from general hospitals.
• Comparison of fiscal year 1984 data (post-PPS) with pre-PPS benchmarks.
• Stratification of analysis based on hospital type (with or without exempt psychiatric units).

Main Results:

• Overall length of stay for Medicare psychiatric patients decreased by 13.8% and charges per discharge by 15.9% post-PPS.
• Despite 31.8% of discharges being from exempt psychiatric units, significant reductions were observed.
• Hospitals without psychiatric units experienced a more substantial decrease in length of stay (23.2%) compared to those with exempt units.

Conclusions:

• The prospective payment system (PPS) effectively reduced resource use among Medicare psychiatric patients in general hospitals.
• The impact of PPS on resource utilization varied by hospital type, with non-exempt units showing greater efficiency gains.
• Findings suggest that payment reforms can influence care patterns and cost-effectiveness in psychiatric hospital services.
