RESUMO
OBJECTIVE To investigate the status of nosocomia infection and provide scientific reference for nosocomial infection control.METHODS Retrospective analysis based on the nosocomial infection materials of January,April,July,October,from 2006 to 2007 were conducted.RESULTS Both the infection incidence and the infection ratio were 4.66% and 5.97%,The main infection sites were lower respiratory tract,urinary tract and gastrointestinal tract.The risk factors were central venous catheters,urine catheters and mechanical ventilation.The nosocomial infection cases were compared with non-nosocomial infection control cases in age,number of days in hospital,death rate and medical treatment fee.There were significant difference between them.CONCLUSIONS It is an efficiency step in preventing infection from central venous catheters,urine cathters and mechanical ventilation,protecting sensitized hosts and developing the prospective analysis of nosocomial infection monitoring.
