ObjectiveTo analyze targeted surveillance results of nosocomial infection in Neurosurgical Intensive Care Unit (ICU) and investigate the characteristics of nosocomial infection, in order to provide reference for constituting the intervention measures. MethodsWe monitored the incidence of nosocomial infection, the application and catheter-related infection of invasive operation, and the situation of multiple resistant bacteria screening and drug resistance characteristics of each patient who stayed more than two days in neurosurgical ICU during January to December 2013. ResultsThere were a total of 1 178 patients, and the total ICU stay was 4 144 days. The nosocomial infection rate was 4.92%, and the day incidence of nosocomial infection was 13.75‰. The nosocomial infection rate was significantly higher in January and between July and December compared with other months. Ventilator utilization rate was 9.75%; ventilator-associated pneumonia incidence density was 14.85 per 1 000 catheter-days; central line utilization rate was 28.40%; central line-associated bloodstream infection incidence density was 0.85 per 1 000 catheter-days; urinary catheter utilization rate was 97.90%; and the incidence density of catheter-associated urinary tract infection was 0.25 per 1 000 catheter-days. ConclusionThe nosocomial infection rate has an obvious seasonal characteristic in neurosurgical intensive care unit, so it is necessary to make sure that the hospital infection control full-time and part-time staff should be on alert, issue timely risk warning, and strengthen the risk management of hospital infection.
ObjectiveTo analyze epidemic characteristics of multidrug-resistant organism (MDRO) in Neurosurgical Intensive Care Unit (NSICU), and to analyze the status of infection and colonization, in order to provide reference for constituting intervention measures. MethodsPatients who stayed in NSICU during January 2014 to April 2015 were actively monitored for the MDRO situation. ResultsA total of 218 MDRO pathogens were isolated from 159 patients, and 42 cases were healthcare-associated infections (HAI) among 159 patients. The Acinetobacter baumannii was the most common one in the isolated acinetobacter. Colonization rate was positively correlated with the incidence of HAI. From January to December, there was a significantly increase in the colonization rate, but not in the incidence of HAI. ConclusionThe main MDRO situation is colonization in NSICU. The obvious seasonal variation makes the HAI risk at different levels. So it is necessary that full-time and part-time HAI control staff be on alert, issue timely risk warning, and strengthen risk management. The Acinetobacter baumannii has become the number one target for HAI prevention and control in NSICU, so their apparent seasonal distribution is worthy of more attention, and strict implementation of HAI prevention and control measures should be carried out.
