Abstract:

To investigate the incidence of nosocomial infections (NI) in integrated intensive care unit (ICU) patients and its risk factors in order to take measures to prevent infections.  MethodsNosocomial infections of ICU patients in Qilu Hospital of Shangdong University from January to December 2008 were investigated and analyzed using the method of prospective investigation. ResultsOf the 330 patients investigated, 111(33.64%) suffered from NI, and the NI rate per day was 25.92‰. The average severity of illness score was 4.40 and the adjusted day infection rate was 5.89‰. The associated NI rates in ventilator, vascular catheter and urinary catheter were 36.17‰, 5.38‰ and 3.69‰ respectively. The main infection site was the lower respiratory tract, and the main bacteria were Gram negative bacilli and Gram positive cocci. The risk factors for NI included the using of ventilator, vascular catheter, urinary catheter and immunosuppressant (P＜0.05). The lower respiratory tract infection rate was significantly higher in patients using a ventilator than in those not using a ventilator (P＜0.01). ConclusionsNosocomial infection rate in patients of integrate ICU is high. In order to gradually reduce the incidence of nosocomial infection, intervention and management of traumatic operation should be paid close attention.
