Abstract:
Objective To explore the risk factors of nosocomial infections to provide a reference for prevention and control of nosocomial infection.Methods The data of 680 patients with nosocomial infection in this hospital from January 2015 to December 2016 were retrospectively collected.The characteristics of nosocomial infection were analyzed from the aspects of age,hospitalization department,infection site,etc.Results A total of 680 cases of nosocomial infection accounted for 1.67％(680/40 657) of all hospitalization patients,including 316 cases(nosocomial infection rate was 2.47％) of 61-80 years old.The infection rate was the highest in ICU(24.90％),followed by the nephrology department(4.99％).For infection sites,the maximal cases-times in infection site was lower respiratory tract(413 case-times),followed by urinary tract and superficial incision(each 68 case-times).The pathogenic detection rate was 45.03％,and 190 strains of pathogens were detected.The top five places were Escherichia coli(47 strains),Klebsiella pneumoniae(28 strains),Pseudomonas aeruginosa (23 strains),Staphylococcus aureus (22 strains) and Bauman Acinetobacter (16 strains).Logistic regression analysis showed that age larger than 60 years old,hospitalization time longer than 60 d,indwelling urinary catheter,peripherally inserted central catheter(PICC),tracheotomy and enteral nutrition were the risk factors for nosocomial infection occurrence.Conclusion Hospital should put the emphasis on preventing nosocomial infection of lower respiratory tract and strengthen the nosocomial infection management of key departments like ICU.
