Abstract：Objective To investigate the occupational exposure to blood-borne pathogens among medical workers in a tertiary general hospital in Hangzhou City from 2010 to 2022, so as to provide the evidence for improving occupational protective measures among medical workers. Methods The registration and follow-up data of occupational exposure to blood-borne pathogens among medical workers from 2010 to 2022 were collected from the blood-borne occupational exposure monitoring system in a tertiary general hospital in Hangzhou City. The population distribution, occurrence, protection and disposal of occupational exposure to blood-borne pathogens were analyzed using a descriptive epidemiological method. Results A total of 1 230 cases were reported with occupational exposure to blood-borne pathogens among medical workers in the study hospital from 2010 to 2022, with the highest incidence in 2021 (4.67%) and the lowest incidence in 2010 (0.99%). The incidence of occupational exposure to blood-borne pathogens appeared a tendency forwards a rise from 2010 to 2022 (P<0.05). Of all cases with occupational exposure to blood-borne pathogens, there were 934 women (75.93%), 656 nurses (53.33%), and 514 cases with working experiences of one year and shorter (41.79%). Hand was the predominant site of occupational exposure to blood-borne pathogens (92.03%) and ward was the predominant place of exposure (35.37%), while scalp needle was the predominant mode of exposure (32.68%), and removal of needle was the predominant procedure of exposure (32.36%). A total of 1 106 cases were tested for the blood-borne pathogens in the exposure sources, and 448 cases were tested positive for blood-borne pathogens, with a detection rate of 40.51%. Hepatitis B virus, treponema pallidum and human immunodeficiency virus were the three most common blood-borne pathogens, and there were 739 cases (60.08%) with personal protective equipment during exposure. Following the follow-up surveillance for more than 6 months post-exposure, no infections occurred. Conclusions Junior nurses and hand exposure were predominant among medical workers with occupational exposure to blood-borne pathogens in the study hospital from 2010 to 2022, and hepatitis B virus was the predominant blood-borne pathogen. No post-exposure infections occurred.
