Abstract:
Objective:To investigate the characteristics of nosocomial infection and relative risk factors, and provide the basis for the management and control of nosocomial infection.Methods:A cross-sectional survey was conducted on all inpatients with nosocomial infection in the First Affiliated Hospital of Shandong First Medical University from 0:00 to 24:00 on September 18, 2018.Results:There were 2 766 inpatients in the survey day, and the detection rate was 100%. The number of nosocomial infections was 57, with a current incidence rate of 2.06% (57/2 766), and the number of infections was 60, with a secondary incidence rate of 2.17% (60/2 766). The departments with the highest infection rates were neurosurgery department and intensive care units (ICU), which were 9.92% (13/131) and 9.38% (6/64) respectively. The lower respiratory tract at the infected site was the first, accounting for 50.00% (30/60). The main pathogens of nosocomial infection were gram-negative bacteria. The incidence of nosocomial infection was higher in patients with age ≥60 years ( χ2 value was 18.22 , P<0.001), ventilator( χ2 value was 37.84 , P<0.001), urinary tract intubation ( χ2 value was 180.57 , P<0.001), diabetic nephropathy ( χ2 value was 34.71 , P<0.001), and hemodialysis ( χ2 value was 368.60 , P<0.001) with statistically significant differences (all P<0.05). Conclusions:The focus should be on the prevention and treatment of lower respiratory tract infection inpatients in the intensive care unit of neurosurgery, and medic should develop preventive measures to avoid the occurrence of nosocomial infection according to the risk factors of patients with age ≥60 years, ventilator, urinary tract intubation, diabetic nephropathy, and hemodialysis to shorten hospital stay and costs.
