Application of disease diagnosis-related grouping in nosocomial infection surveillance
OBJECTIVE To explore the application of the disease diagnosis-related grouping(DRGs)approach in nosocomial infection monitoring.METHOD The basic information of discharged cases,DRGs,hospitalization days,hospitalization costs and nosocomial infection in the Affiliated Hospital of Guizhou Medical University from Jan.1 to Dec.31,2022 were retrospective analyzed.RESULTS Before the adjustment of the incidence rate of noso-comial infections,the top five clinical departments were ICU,cardiac surgery,gastrointestinal surgery,hematolo-gy,and neurology.After the adjustment of the value using the case-mix index(CMI),the top five were hematolo-gy,gastrointestinal surgery,neurosurgery,ICU and rehabilitation wards.The top five DRG groups in the number of nosocomial infection cases were RB19,GB23,RR13,AG29 and RE19.The top five DRG groups in the inci-dence rate of nosocomial infection were RR21,AG29,RR11,GB11 and IC23.Among the top five DRG groups in the number of nosocomial infection cases,the median hospitalization days in the nosocomial infection group were higher than that in the non-nosocomial infection group(P＜0.05).In terms of hospitalization costs,except for AG29,the median hospitalization costs of the other top five DRG groups were higher than those of the non-hospi-talization groups(P＜0.05).CONCLUSIONS DRGs can be applied to nosocomial infection surveillance,and CMI value can be used to standardize nosocomial infection incidence index.Calculating the incidence of nosocomial infec-tion in different DRG groups is conducive to the development of precise control of infection.
