Early Impact on Outpatients of Mandatory Adoption of the Diagnosis-Related Group-Based Reimbursement System in Korea on Use of Outpatient Care: Differences in Medical Utilization and Presurgery Examination.

ABSTRACT:

Objective

To explore the impact of mandatory adoption of diagnosis-related groups (DRGs) on the use of outpatient care in Korea.

Data sources

National Health Claim data from 2,022 hospitals and 1,029,101 admission cases during 2011-2014: tonsillectomy/adenoidectomy, inguinal/femoral hernia operation, and hemorrhoidectomy.

Study design

Outcome variables included probability of outpatient visit, number of outpatient visits, and outpatient medical expenditures within 30 days. Presurgery examination before hospitalization for surgery, including basic and other examination, was conducted to evaluate a possible shift in health care service. A difference-in-difference research design was used to evaluate the impact of the DRG system on the use of outpatient care.
