Objective To investigate the relationship between occurrence of healthcare-associated infection (HAI)and seasonal change,so as to provide the basis for seasonal HAI prevention and control.Methods The occurrence of HAI among inpatients in a hospital between 2010 and 2013 was analyzed retrospectively.Results Of 303 371 patients,10 376 developed 12 919 cases of HAI,the incidence of HAI was 3.42%,infection case incidence was 4.26%.The highest inci-dence of HAI occurred in the fourth quarter(3.76%)and lowest in the second quarter (3.20%)(P 5%intensive care unit(ICU,24.61%),hematology(17.47%),rehabilitation(13.16%),neurosurgery(9.27%),infectious diseases (9.17%),cardiothoracic surgery(7.67%),and hepatobiliary surgery(5.13%),the main HAI sites in patients in ICU,department of neurosurgery were lower respiratory tract,blood stream,and urinary tract.Conclusion The occu-rrence of HAI is closely related with seasonal change,appropriate control measures should be taken according to seasonal change and sites of high HAI rates,so as to reduce the occurrence of HAI.
