Japanese hospitals use a diagnosis procedure combination (DPC) prospective payment system (PPS) to increase income by shortening average length of stay (ALOS) and patient numbers. A new simulation program helps predict optimal ALOS and patient counts for each DPC to maximize hospital revenue.

Area of Science:

  • Health Economics
  • Hospital Management
  • Health Services Research

Background:

  • Japan introduced a diagnosis procedure combination (DPC) prospective payment system (PPS) in April 2003 for acute care hospitals.
  • Under DPC/PPS, hospitals aim to increase revenue by reducing average length of stay (ALOS) and increasing patient volume.

Purpose of the Study:

  • To develop a simulation program to analyze the relationship between ALOS, bed occupation rate (BOR), and hospital income under DPC/PPS.
  • To identify optimal ALOS and patient numbers for each DPC to maximize hospital income.

Main Methods:

  • Construction of a simulation program to model DPC/PPS financial dynamics.
  • Inputting and regulating ALOS and patient numbers for individual DPCs within the simulation.
  • Evaluating the impact of these adjustments on overall hospital income and BOR.

Main Results:

  • The simulation program accurately evaluates hospital income by adjusting ALOS and patient counts per DPC.
  • The tool enables prediction of optimal ALOS and inpatient numbers for each DPC to enhance financial performance.

Conclusions:

  • The developed simulation program is a valuable tool for hospitals operating under DPC/PPS.
  • It facilitates strategic decision-making to optimize operational parameters for increased hospital income.
