Shift work has been found to be associated with an increased rate of errors and accidents among healthcare workers (HCWs), but the effect of shift work on accidental blood and body fluid exposure sustained by HCWs has not been well characterized.
To determine the duration of time on shift before accidental blood and body fluid exposure in housestaff, nurses, and technicians and the proportion of housestaff who sustain a blood and body fluid exposure after 12 hours on duty.
This retrospective, descriptive study was conducted during a 24-month period at a large urban teaching hospital. Participants were HCWs who sustained an accidental blood and body fluid exposure.
Housestaff were on duty significantly longer than both nursing staff (P=.02) and technicians (P<.0001) before accidental blood and body fluid exposure. Half of the blood and body fluid exposures sustained by housestaff occurred after being on duty 8 hours or more, and 24% were sustained after being on duty 12 hours or more. Of all HCWs, 3% reported an accidental blood and body fluid exposure, with specific rates of 7.9% among nurses, 9.4% among housestaff, and 3% among phlebotomists.
Housestaff were significantly more likely to have longer duration of time on shift before blood and body fluid exposure than were the other groups. Almost one-quarter of accidental blood and body fluid exposures to housestaff were incurred after they had been on duty for 12 hours or more. Housestaff sustained a higher rate of accidental blood and body fluid exposures than did nursing staff and technicians.
研究发现轮班工作与医护人员（HCW）的差错和事故发生率增加有关，但轮班工作对医护人员意外血液和体液暴露的影响尚未得到充分描述。
确定住院医师、护士和技术人员在意外血液和体液暴露前的轮班时长，以及住院医师在值班12小时后发生血液和体液暴露的比例。
这项回顾性描述性研究在一家大型城市教学医院进行，为期24个月。研究对象为发生意外血液和体液暴露的医护人员。
住院医师在意外血液和体液暴露前的值班时间显著长于护士（P = 0.02）和技术人员（P < 0.0001）。住院医师发生的血液和体液暴露中有一半发生在值班8小时或更长时间之后，24%发生在值班12小时或更长时间之后。在所有医护人员中，3%报告有意外血液和体液暴露，其中护士的暴露率为7.9%，住院医师为9.4%，采血员为3%。
与其他组相比，住院医师在血液和体液暴露前的轮班时间显著更长。住院医师发生的意外血液和体液暴露中，近四分之一是在值班12小时或更长时间之后发生的。住院医师意外血液和体液暴露的发生率高于护士和技术人员。
