Methods Thirty-nine cases whose CRKP isolation and culture were positive and who were confirmed with nosocomial infection in 2nd affiliated hospital medical school of Zhcjiang University between July 2006 and July 2008 were retrospectively investigated. Results There were 22 (56.4%) sputum specimens among CRKP samples. The average age of the patients was 64.0 years old and the average length of staying in hospital was 80.8 days. There wcre 36 patients who had been in intensive care unit (ICU) within 2 weeks and 26 were conscious disturbance,38 received urethral catheterization, 34 inserted with central venous catheter, 32 received tracheal intubation and 30 assisted with mechanical ventilation. There were 27 (69. 2 % ) patients who were co-infected with other bacteria and 8 were co-infccted with fungi. The mortality was 46. 2% in patients with CRKP infection. Before CRKP-positive culture, 27 (69.2%)experienced ＞4 kinds of antibiotics with the majority of β-lactams/β-lactamase inhibitors and carbapenems.Conclusions CRKP infection frequently occurrs in elder and patients who prolonged stay in hospital,especially patients in ICU.
