Abstract:

Objective To understand the characteristics and changing trend of nosocomial infection in the intensive care unit (ICU) in a tertiary hospital in Beijing for evidence to formulate prevention and control measures for nosocomial infection. Methods The clinical data of all nosocomial infection cases reported by a tertiary hospital in Beijing from 2017 to 2022 was derived through the Beijing Nosocomial Infection Surveillance and Management System, and analyzed pertinent to the changing trends by year of nosocomial infection proportion, incidence rate, age group, infection site and pathogens responsible for the infection. Results A total of 3 001 ICU patients were monitored, and 160 cases (195 times) of nosocomial infection occurred in 2017-2022, with overall nosocomial infection rate of 5.33%. The infection rates from 2017 to 2022 were 4.61% (20/434), 8.02% (38/474), 7.16% (34/475), 4.90% (21/429), 3.29% (24/730) and 5.01% (23/459), respectively, which indicated a decreasing trend (Z=2.061, P<0.05). The average daily nosocomial infection incidence was 0.55% (160/28 987) from 2017 to 2022. The median age for the ICU infections was 70.0 (57.5, 80.0) years, and the infection most occurred in patients aged 60 years or older (72.50%, 116/160). The most common infection site was in respiratory system (46.67%, 91/195), followed by blood system (33.85%, 66/195). The top three pathogens responsible for the nosocomial infection were involved in Klebsiella Pneumoniae (16.88%, 27/160), Acinetobacter baumannii (14.38%, 23/160) and Pseudomonas aeruginosa (13.75%, 22/160). Conclusion The incidence of nosocomial infections of ICU of this hospital was lower, and the incidence tended to decrease from 2017 to 2022. The infections mainly occurred in the elderly population, and respiratory infections are the main pathway. Gram negative bacteria are the major pathogens causing the infections. The findings suggest that attention should be paid to the key populations for nosocomial infections in ICU through implementation of the prevention and control measures and strengthening targeted surveillance in order to reduce the risk of nosocomial infection.
