Implementation of the diagnosis procedure combination in specific-function hospitals

Area of Science:

• Health Economics
• Medical Policy
• Hospital Management

Background:

• The Diagnosis Procedure Combination (DPC) payment system was introduced in Japan in 2003.
• This system bases payments on diagnosis and procedures, differing from previous fee-for-service models.
• The DPC system categorizes patients into nearly 2,500 groups based on ICD-10 codes and procedures.

Purpose of the Study:

• To evaluate the impact of the DPC payment system on hospital practices.
• To explore strategies for reducing hospital length of stay under the new system.
• To improve patient care and clinical practices within a transitioning healthcare landscape.

Main Methods:

• Implementation of the DPC payment system in specific-function hospitals.
• Development of clinical pathways for common surgical procedures (e.g., laparoscopic cholecystectomy, gastrectomy).
• Creation of clinical protocols for specific surgical interventions (e.g., PTCD, PEG).

Main Results:

• The DPC system aims to decrease the length of hospital stays, with official ranges of 14 to 30 days.
• The system is expected to foster competition among hospitals.
• Clinical pathways and protocols were developed to support reduced lengths of stay.

Conclusions:

• The DPC payment system represents a significant shift in healthcare reimbursement in Japan.
• Clinical pathways and protocols are key tools for managing hospital stays under the DPC system.
• Continuous improvement in patient care and clinical practice is essential during this healthcare transition.
