Abstract Objective： To know the risk factors of occupational exposure among nursing staff， in order to provide some effective protective measures for them and reduce the risk of occupational exposure. Method： Through the analysis and summary which contrapose to the 37 occupational exposure registration of nurses in our hospital. Result： Among total 364 nurses（ including student nurses）， 37 nurses suffered the occupational exposure（ 37/364，10.16％）. The exposure
categories include sharp injuries， skin injuries and the others. 89.19% was sharp injuries（ needle stick injuries account for 94.12% in sharp injuries） and skin injuries account for 10.81%， 5.58% for the others. 15 cases（ 14 person-time） were exposed to hepatitis B cases blood（ 39.47％） ，3 cases were exposed to hepatitis C patient blood（ 7.89％）， 2 cases were exposed to the HIV-positive cases blood（ 5.26 ％）， 2 cases were exposed to the treponemapallidum（ 5.26%）， 3 cases were not exposed to the pathogens of hematogenous infection（ 10.53%） and the rest were not sure（31.58%）. 27 in the 37 nurses who suffered the occupational exposure haven’t been infected by occupational exposure during more than six months’follow-up. The others haven’t been infected by occupational exposure during more than three months’ follow-up. Conclusion： Nurses are the high-risk group of sharp injuries， especially needle stick injuries.
