Abstract:
OBJECTIVE To investigate the causes of abnormal rising trends of isolation rate and infection of Staph-ylococcus aureus in the breast surgery department of a specialized cancer hospital.METHODS By means of pro-spective survey in combination with retrospective survey,an epidemiological survey was conducted for 5 patients with hospital-associated S.aureus infection who were treated in breast surgery department of Sun Yat-sen Univer-sity Cancer Center from Jan.2023 to Aug.2023,and the homology was observed.RESULTS The incidence rate of hospital-associated S.aureus infection(ward E 0.08％,ward F 0.38％)of the breast surgery department patients was higher during the period from Jan.2023 to Aug.2023,higher than 0.004％of the whole patients during the same period.The environmental sampling result showed that the colonized rate of S.aureus was 17.39％(4/23)and in nasal cavity 7.41％(2/27)in hands of the healthcare workers,and 28.57％in nasal cavity of logistical per-sonnel.Bundle interventions could reduce the incidence of hospital-associated methicillin-resistant S.aureus(MRSA)infection and the colonized rate in hands of the healthcare workers but had less impact on the colonized rate in the nasal cavity.The result of pulse field gel electrophoresis(PFGE)indicated that there was risk of cross transmission of colonized S.aureus between the hands of healthcare workers and the nasal cavities.The hand hy-giene,measures for contact transmission and environmental disinfection were supposed to be taken as the major links for control of the hospital-associated S.aureus infection.CONCLUSIONS The sporadic community-ac-quired infections and hospital-associated infections are the leading causes of the abnormal rise of the isolation rate and the infection rate of S.aureus in the breast surgery department.The bundle prevention and control measures can block the transmission of infections.
