Occupational Exposure to Positive Blood and Body Fluids among Health Care Workers in a Chinese University Hospital: A Three Years Retrospective Study.

Health care workers (HCWs) are exposed to blood and body fluids (BBF) due to occupational accidents. However, few studies have investigated the prevalence of occupational exposure in Chinese HCWs thus far. There is a clearly a critical need to characterize its epidemiology more fully in China so that effective prevention programs can be implemented. We conducted a retrospective study at a university hospital in China, giving an epidemiological analysis on these exposed HCWs whose pathogens of BBF from patients were positive [human immunodeficiency virus (HIV) / hepatitis B (HBV) / hepatitis C (HCV)]. From July 1st 2011 to June 30th 2014, a total of 155 occupational exposures to positive BBF were reported, with an incidence of 16.64 (/1000 person-years). Percutaneous injuries were the most common type of exposure episodes (89.03%). The most common type of exposed blood-borne pathogens was HBV (83.87%), and the majority of the respondents were nursing students, with an incidence of 34.22 (/1000 person-years). More effective preventive strategies on HCWs' BBF occupational exposure should be implemented in China, especially for nursing students.
