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.
Article in Health services research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo 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
designOutcome 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. PRINCIPAL
findingsBefore the introduction of the DRG system, 384,609 (91.1 percent) participants used an outpatient clinic either before or after hospitalization. In our study, the number of outpatient visits and outpatient medical expenditures within 30 days increased after mandatory adoption of the DRG system. After adoption of the DRG system, volume and costs for presurgery examinations increased before hospitalization.
conclusionWe observed a spillover effect after mandatory adoption of the DRG system. A future payment system should be designed for spillover effects, and the introduction of a new payment system that expands the DRG-based reimbursement system should be considered.
