Surveillance of healthcare-associated infection in hospitalized patients in a comprehensive hospital of Jiaxing

Abstract

Objective To understand the characteristics of healthcare-associated infection (HAI) in hospitalized patients, and to provide references for HAI control and prevention. Methods By real-time monitoring system of HAI and retrospective investigation, 240 709 patients hospitalized in the First Hospital of Jiaxing from July 1st, 2016 to June 30th, 2018 were enrolled to analyze the incidence rate, infection site, pathogens and departments. Results The incidence rate of HAI was 2.30% (5 546 patients) and the infection rate was 2.40% (5 781 episodes) . The incidence rate and infection rate of HAI showed decreasing trends (χ2=140.45, 153.66, P<0.01) . The main infection sites of HAI were lower respiratory tract (47.34%) , urinary tract (15.81%) and upper respiratory tract (9.31%) . Departments of ICU (14.63%) , neurosurgery (6.42%) , hematology (6.10%) and cardiothoracic surgery (5.69%) had high incidence rates of HAI. Escherichia coli, Klebsiella pneumonia, Acinetobacte rbaumannii, Staphylococcus aureus and Pseudomonas aeruginosa were the most common pathogens of HAI. Gram-negative bacteria were the main pathogens, accounting for 66.20%. Conclusions The incidence rate of HAI in the First Hospital of Jiaxing is low, and shows a decrease trend. It is necessary to strengthen the monitoring and management of the infection sites, departments, pathogens with high incidence of HAI, and take effective measures to prevent and control HAI.
