Occupational exposure to bloodborne pathogens among health care workers in a general hospital in Shenzhen in recent five years
Objective:To characterize the blood-borne occupational exposures among healthcare workers in a tertiary general hospital in Shenzhen from 2019 to 2023 and determine the influencing factors,aiming to provide insights for continuously improving the management of occupational exposures and strengthening the protective measures.Methods:An observational descriptive study was performed by a retrospective retrieval of five-year data of exposures to blood among healthcare workers in a tertiary general hospital in Shenzhen.The demographic distribution,exposure routes and exposure sources were descriptively statistically analyzed.Results:From 2019 to 2023,a total of 359 cases of blood-borne occupational exposures were reported.The annual incidence rate fluctuated,of which the highest was 3.59%in 2019 and the lowest was 1.53%in 2022.The exposure mainly occurred in the second half of the year.The majority of the affected individuals were female and nurses,with 79.39%of them having less than 5 years of work experience.84.68%of occupational exposures were caused by sharp instrument injuries,mainly occurring during needle withdrawal and disposal(22.70%)and surgery(21.05%).The main exposure sites included ward(42.34%)and operation rooms(20.61%).Most of exposure sources were tested negative for blood-borne pathogens except for 131 cases.The top three pathogens were hepatitis B virus,Treponema pallidum and hepatitis C virus.Follow-up monitoring suggested that 77.78%of the exposed individuals completed the recommended preventive medication and no post-exposure infection occurred after exposure.Conclusion:The blood-borne occupational exposure reported in this hospital during 2019 and 2023 was mainly needle stick injuries in junior nurses,and the main pathogen exposed was hepatitis B virus.No post-exposure infection occurred.Nurses are high-risk group of occupational exposure,and the prevention of needle-stick injury calls for our great concern.Meanwhile,vaccination against pathogens from occupational exposure especially hepatitis B,should be paid great attention as an effective protective measure.
