目的定量评估医务人员血源性疾病感染风险。方法调查乡镇卫生院基层医务人员锐器刺伤情况以及乙肝疫苗免疫率,采用Kane模型计算个人年感染概率。结果429名医务人员平均年锐器刺伤率50.82%,每人年刺伤频数为1.05,乙肝疫苗免疫率72.03%。HBV、HCV、HIV每万人年风险感染例数分别为239、99和0.08。结论通过锐器刺伤以及乙肝疫苗免疫率调查可以定量评估医务人员HBV等血源性疾病感染风险。
Objective To quantitatively assess the risk of blood-borne diseases among medical staffs. Methods Investigate the sharp stab wounds of primary medical staff in township hospitals and the immunization rate of hepatitis B vaccine, and calculate the probability of annual infection by Kane model. Results 429 medical staff average annual sharp injury rate of 50.82%, per person annual stab wound frequency of 1.05, hepatitis B vaccine immunization rate of 72.03%. The number of risk infections per million people of HBV, HCV and HIV was 239, 99 and 0.08, respectively. Conclusions The risk of blood-borne diseases such as HBV among medical staff can be quantitatively assessed through the stab wounds and hepatitis B vaccine immunization rate survey.
