Investigation on prevalence rate of nosocomial infections in 1002 inpatients

OBJECTIVE To understand the infection situation and discover the potential problems with nosocomial infections,so as to improve the measures for prevention and control.METHODS The cross-sectional study was performed and the inspectors were unified trained.Medical records were accessed and bedside visit to patients was performed in specified period.The questionnaires were filled.Inspection results were statistically analyzed.RESULTS Totally 1016 patients should be inspected and 1002 cases were actually inspected with the inspection rate of 98.6%.The prevalence rate of nosocomial infection was 3.7%,and the case-time infection rate was 3.9%.Respiratory tract infection ranked NO 1 in all the nosocomial infection sites,among which lower respiratory tract infection accounted for 41.0%,upper respiratory tract infection accounted for 20.5%,and gastrointestinal tract infection accounted for 10.3%;the submission rate of etiological examination for nosocomial infection cases was 38.5%;195 cases were community-acquired infection with the submission rate of etiological examination of 27.2%;the use rate of antibiotics was 55.6%.The submission rate of bacterial culture for the drug treatment was 29.0%.CONCLUSION The inspection of prevalence rate can reflect the actual infection situation,risk factors,and major existing problems in hospital,which can help us to control nosocomial infection and improve the measures as well as enhance the quality management and control the incidence of nosocomial infection.
