Target surveillance of hospital infection in intensive care unit

2011 
OBJECTIVE To investigate the incidence and risk factors of hospital infection in an intensive care unit(ICU) in order to use surveillance data to develop and evaluate strategies to prevent and control nosocomial infections.METHODS The target surveillance of hospital infection in an ICU were carried out according to the method involved in the Nosocomial Infections Surveillance System developed by Ministry of Health,P.R.China.Monitoring objects had derived from an ICU inpatients lasted through Apr 2009 to Mar 2010.RESULTS From total 404 patients which the length of stay were more than 48 hours,130 cases occurred to hospital infection and the daily infection rate was 2.51%.Among the 3 kinds of invasive operation related infection,breathing machine resides first place with the infective rate of 25.71%,indwelling catheter and central venous catheterization comes second which accounted for 5.45% and 2.48%,respectively.The main pathogenic bacteria isolated from sufferers included Pseudomonas aeruginosa(25.30%),Baumanii(21.95%),Staphylococcus aureus(13.11%) from which the proportion of methicillin resistant S.aureus(MRSA) was higher up to 12.81%,K.pneumoniae(7.93%),Candida albicans(11.89%).CONCLUSION The inpatients in ICU are the susceptible population of nosocomial infections.The data collected with the use of the target surveillance in an ICU are effective and efficient ways to assess the influence of patient risk,which can be used by hospitals to set priorities for their infection control programs.
