Pathogens,risk factors and economic burden of nosocomial infection among death cases in a tertiary hospital
OBJECTIVE To analyze the characteristics of the death cases with nosocomial infection in a tertiary hos-pital so as to provide bases for medical institutions to put forward targeted measures for management of nosocomi-al infection.METHODS The status of nosocomial infection among the death cases in a tertiary teaching hospital in the whole year of 2022 was retrospectively analyzed,including disease diagnosis related grouping(DRG),nosoco-mial infection sites,pathogens causing the infection,drug resistance,risk factors and economic burden.RESULTS The case-time incidence rate of nosocomial infection was 9.8%among the death cases,and the death cases with lower re-spiratory tract infection and bloodstream infection were dominant.GB11,RR13 and BK19 ranked the top 3 DRG of the death cases.Totally 51 strains of pathogens were isolated from the death cases with nosocomial infection,34(66.7%)of which were gram-negative bacteria,9(17.6%)were gram-positive bacteria,and 8(15.7%)were fungi.Length of hos-pital stay more than 15 days,use of antibiotics more than 20 days,use of ventilator,diabetes mellitus and cardiovascular diseases were the risk factors for the death of the nosocomial infection cases.As compared with the death cases without nosocomial infection,the length of hospital stay of the death cases with nosocomial infection was increased by 21.5 days,and the hospitalization cost was increased by 97 801.7 yuan.CONCLUSION The prevention and control of nosocomial infection should be stressed on the patients undergoing esophageal and gastrointestinal surgeries and the acute leu-kemia patients,it should focus on the emergence of lower respiratory tract infection and bloodstream infection and remain vigilant with the high lethality rate and high drug resistance rate caused by CRKP infection.
