A time/motion study performed in the Department of Anesthesiology at Ohio State University divided intraoperative events into three categories: (1) patient-centered, direct--activities that direct the anesthesiologist's attention to the patient; (2) patient-centered, indirect--observation of equipment or data related to patient status; and (3) non-patient-centered--activities that direct the anesthesiologist's attention away from the patient. Surprisingly, results of this study did not differ greatly from those of earlier investigators, who found that the anesthesiologist was distracted from the patient 46% of the time. Future studies and monitor development should address this problem by reducing non-patient-centered activities and distractions to the anesthesiologist during surgery.
俄亥俄州立大学麻醉学系进行的一项时间/动作研究将术中事件分为三类：（1）以患者为中心的直接活动——将麻醉医生的注意力引向患者的活动；（2）以患者为中心的间接活动——对与患者状态相关的设备或数据的观察；（3）非以患者为中心的活动——将麻醉医生的注意力从患者身上引开的活动。令人惊讶的是，这项研究的结果与早期研究者的结果并无太大差异，早期研究者发现麻醉医生有46%的时间会分心而无法关注患者。未来的研究和监测设备的开发应通过减少手术期间非以患者为中心的活动和对麻醉医生的干扰来解决这一问题。
