ABSTRACT
Objective To understand the characteristics of population distribution,risk factors and risk links of occupational exposure among health care workers(HCWs)in a hospital.Methods Occupational exposure among HCWs between January 2011 and June 2014 were monitored,data about occupational categories of HCWs,expo-sure locations,exposure links and exposure modes were analyzed statistically.Results Among 286 occupational ex-posure cases,the female and male HCWs accounted for 22.03% (n=63)and 77.97% (n=223)respectively;the incidence of occupational exposure in 2011 ,2012,2013 and January-June of 2014 was 38.81 %(n=111),26.22% (n=75),23.43% (n=67)and 11 .54% (n=33)respectively;occupational exposure of junior nurses,doctors,nurs-ing attendants,technicians,senior nurses and cleaners was 31 .97%,19.90%,15.79%,7.64%,4.17%,and 2.84% respectively;exposure mainly occurred at the time of sorting waste,withdrawing or changing needles,dis-carding sharps into sharps containers,surgical suturing or instruments passing,and puncturing (including drawing blood),the constituent ratio was 22.38%,19.58%,14.34%,12.94% and 11 .19%,respectively;the main loca-tions where exposure occurred were wards,operating rooms and injection (treatment)rooms,the constituent ratio was 51 .40%,19.58% and 11 .54% respectively.Conclusion Hospital should establish comprehensive occupational exposure monitoring and risk management system,strengthen standard prevention,enhance the training about occu-pational exposure among high-risk population,and monitor and intervene on risk factors and links,so as to reduce the incidence of HCWs’occupational exposure.
