Abstract:
Objective To investigate the characteristic of intravascular catheter-related infections (CRI) in Peking University Third Hospital in 2009. Methods The clinical and microbiological features of CRI were analyzed retrospectively. Results Two hundred and nineteen catheters were examined. Twenty-nine CRI cases were confirmed with colonization, 7 were insertion site infection and 6 were catheter-related bloodstream infections (CRBSI) by quantitative catheter culture method, but no CRBSI was diagnosed by differential time to positivity (DTTP) method. The incidence rates of CRBSI in intensive care units (ICU) were 0. 99- 3.03 per 1000 catheter-days.Among the colonized strains, 51.72 % were Gram-positive cocci, 20.69 % were non-fermenting bacilli (NFB), 13. 79% were Enterobacteriaceae and 10. 34% were Candida. One neonatal CRBSI was caused by Leuconostoc mesenteroides. Most of bacterial isolates were drug resistant. Seventy-seven percent of adult patients were older than 60 years and most of them had chronic underlying diseases.All of the 9 neonate patients were preterm neonate and 7 of them were extremely low birth weight infants. Conclusion There is a certain amount of CRI occurred in Peking University Third Hospital in 2009 and the intravascular catheter management should be enhanced.
