ABSTRACT

Objective To investigate occupational exposure among health care workers (HCWs)in a tertiary comprehen-sive hospital,and analyze the causes and preventive measures of occupational exposure.Methods 134 cases of occupational exposure among HCWs in a hospital from January 2010 to December 2013 were analyzed.Results Of HCWs sustained oc-cupational exposure,doctors,nurses,and technicians accounted for 59.70%,19.40%,and 9.70% respectively.The main cause for occupational exposure was non-standardized management of the sharps (46.27%,n=62),followed by unex-pected operation(42.54%,n=57)and inadequate protective measures (11.19%,n=15);The main exposure mode was sharp injury(94.78%,n=127),mucosal exposure accounted for 5.22% (n= 7);42.54% of exposure sources were not clear,57.46% of exposure sources were clear,35.82%,12.69%,3.73%,and 2.24% of which were hepatitis B virus (HBV),hepatitis C virus(HCV),Treponema pallidum(TP),and human immunodeficiency virus(HIV);2.24%(n=3)of exposure sources were co-infection of HBV and HCV;0.74% (n = 1 )was co-infection of HIV,HBV,HCV,and TP. 95.52%of occupational exposures were treated correctly.Conclusion The high-risk population for occupational exposure are nurses,standard occupational precautions and management of the sharps can reduce the occurrence of occupational expo-sure among HCWs.
