Utilization and case-mix impacts of per case payment in Maryland

Area of Science:

• Health economics
• Hospital payment systems analysis
• Healthcare policy research

Background:

• Maryland has utilized both per case and per service hospital payment systems since 1976.
• The stringency of per case rates has varied over time.
• Understanding the impact of these systems is crucial for healthcare management.

Purpose of the Study:

• To compare the effects of per case versus per service payment systems on hospital utilization.
• To analyze the impact on admissions, length of stay, and case-mix costliness.
• To assess the relationship between payment system stringency and utilization responses.

Main Methods:

• Regression analyses were employed to compare the two payment systems.
• Data spanned from July 1, 1976, to June 30, 1981.
• Key performance indicators analyzed included admissions, length of stay, and case-mix costliness.

Main Results:

• The per case payment approach showed a positive effect on hospital admissions.
• Conversely, per case payments were associated with negative effects on case mix and length of stay.
• Increased stringency in per case payment rates correlated with stronger utilization responses.

Conclusions:

• The per case hospital payment system significantly influences utilization patterns compared to the per service system.
• Payment system design and rate stringency are key determinants of hospital admissions and efficiency.
• Findings provide insights for optimizing hospital reimbursement strategies.
