ABSTRACT
Objective To evaluate the performance of medical services of 18 tertiary hospitals in Sichuan province in 2016 based on DRGs, to identify objective methods to evaluate service quality and performance of medical institutions.Methods Based on the homepage data of inpatient medical records from 18 tertiary hospitals in Sichuan in 2016, using diagnosis-related groups as a risk-adjustment tool, the study evaluated the medical service quality and performance from three dimensions:medical ability,service efficiency and medical Quality.Results In the evaluation of medical service capacity, hospital I had the highest number of discharged cases and total weight(83 405 cases and 126 522.22),and hospital G had the lowest discharge cases and total weight(2 350 cases,2 797.12).The highest number of DRGs group was from hospital B(661 groups),and the lowest from hospital G(43 groups).The highest value of CMI was from hospital F(2.091),and the lowest from hospital D(0.953).Hospitals B,I and P had wide disease type range,while hospitals F, B and I had higher overall technical level than the other hospitals.Of the service efficiency evaluation,hospital E had the lowest time consumption index(0.740),and hospital P had the lowest expenditure index(1.073).Of the service quality evaluation,hospitals F and G had the lowest risk of mortality and the lower risk of mortality(0.00%,0.00%).Hospital I had the highest total score (100.0 points), and hospital G had the lowest total score(51.1 points).Conclusions DRGs based evaluation on medical service quality and performance of medical institutions can ensure reliability and scientific adequacy of evaluation.It may contribute to the continuous improvement of medical quality, and provide data support and decision reference for medical service supervision.
