醫療工作環境比較特殊，可能隱藏著一些未知的危害，為暸解醫療院所工作人員在執行業務時可能遭遇的危險，本文整理某醫學中心勞安室6 年來有關於員工在院內遭受意外傷害事件之資料，結果顯示以針扎事件最多；因之，本文探討針扎引起之危害並分析該院早年為員工免費接種B 型肝炎疫苗之措施，經過多年的接種措施，2002至2004 年皆沒有需要注射Hepatitis B immune globulin (HBIG) 的案例出現，似乎已呈現出降低額外醫療支出之效益，且員工被針扎後引發感染B 型肝炎的風險疑慮已大幅降低。

The health care worker is at substantial risk of medical hazards. By analyzing theoccupational health hazard records from a medical center in the past 6 years, we discovered thatneedlestick injury ranked as the highest threat to the health care workers' health. This studyassesses the risk of infection among health care workers from needlestick injuries, and furtheranalyzes the effectiveness of the former precautionary policy of hepatitis B vaccinationadministration among health care workers. Based on this analysis, it is discovered that after manyyears of employee hepatitis B vaccination, no Hepatitis B Immune Globulin usage was needed forthe health care workers from year 2002 to year 2004. This data displays the additional benefit ofreducing unnecessary medical expenditure and the risk associated with contracting heptatis Bfrom needlestick injuries is also diminished.
