ObjectiveTo evaluate the effect of diagnosis-related group (DRG) payment method systematically before and after implementation in terms of average hospitalization day, cost and care quality.MethodRestricted the period from 2019 to May 31, 2023, we use 6 databases from CNKI, Wipu, Wanfang, PubMed, ScienceDirect, and web of science. With the related study, we extract the data about DRG, then we conducted meta-analysis of the data about length of stay (LOS) and cost by RevMan 5.4 and Stata 12.0 software. Care quality is in conjunction with literature reports.ResultAbout 24 articles were included, covering 2 indicators: average hospitalization expenses and days. Meta-analysis shows that implementing DRG payment method has an advantage in terms of average hospital stay (pooled effect: -1.13%, 95% CI: -1.42 to -0.84, P = .00), and the difference is statistically significant. There is also an advantage in average hospitalization expenses (pooled effect: -2.58, 95% CI: -3.38 to -1.79, P = .00), and the difference is statistically significant.ConclusionThe use of DRG payment method can effectively reduce LOS and average hospitalization expenses. However, quality of care may decline with DRG adoption.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
