目的了解医务人员免疫缺陷病毒（HIV）职业暴露风险,做好医务人员血源性病原体职业暴露预防,保护医务人员执业安全。方法对2013-2015年某医院46例确证实验HIV阳性患者各项信息进行统计分析。同时对该医院感染控制科登记随访的45例医务人员职业暴露相关信息进行回顾性分析。结果 2013-2015年间共登记存档医务人员血源性病原体职业暴露45例,以女性护士和实习护士居多,血源性病原体职业暴露主要以针刺伤为主（97.8%）,其中主要病原体为乙肝病毒（44.4%）;接诊HIV阳性患者逐年增加,医务人员HIV职业暴露风险不断加大。结论随着接诊HIV阳性患者增多,医务人员HIV职业暴露风险随之升高,应了解患者血源性病原体感染情况,缩短HIV暴露风险窗口期,同时医务人员应加强岗位培训,做好标准预防措施,降低HIV暴露风险。

英文摘要：

bObjective To analyze the risks posed by HIV occupational exposure among health care workers（ HCWs） in a tertiary hospital in order to take appropriate precautions against blood-borne pathogens and protect the health of HCWs. Methods Clinical data of 46 cases of HIV-positive patients confirmed between 2013 and 2015 was collected and analyzed,and occupational exposure related information of 45 cases of medical staff in the Department of Infection Control of the hospital who were followed up in the same period was analyzed retrospectvely.Results Among the 45 cases of medical staff with occupational exposure related information registered and recorded in the Affiliated Hospital of the Armed Police College from 2013 to 2015,the majority were female nurses and nursing interns,and the main occupational exposure to blood borne pathogens was needle stick injuries（ 97.8%）,while the main pathogen was hepatitis B virus（ 44.4%）. Admissions of patients with positive HIV increased year by year,and the risk of occupational exposure to HIV kept increasing among healthcare providers. Conclusion With the increase of admissions of HIV positive patients,the risk of occupation exposure to HIV is increasing among medical personnel. First-hand information on patients with blood borne pathogen infections should be made available to shorten the window period of HIV exposure. Meanwhile,medical staff should strengthen the on-the-job training,take standard prevention measures in order to reduce the risk of HIV exposure.
