摘　　要：目的:为中南大学湘雅医学院附属医院手术时间预测调度系统的设计提供更全面的参考数据,以提高手术室的利用率。方法:通过文献综述和专家咨询的方法,设计"手术时长影响因素调查问卷",进行信效度检验,确定问卷格式与内容。采用分层抽样,发放问卷,进行统计分析。结果:二维影响因素中,影响程度最高的是外科医师相关因素,程度最低的是患者自身因素;所选的38项一维影响因素对手术时长均有一定的影响,影响程度均值大于2.45。科室不同,对手术时长影响因素影响程度的认同度有差异。结论:手术时长影响因素较多,但外科医师相关因素对手术时长的影响较大,科室不同对麻醉相关因素和外科医师相关因素的认同度有差异。Objective To improve the utilization ratio of operating room in Affiliated Hospital of Central South University Xiangya Medical School by providing more comprehensive reference data for the design of surgical time prediction and dispatch system. Methods A questionnaire was designed according to the review of literature and consultation of experts for investigating the surgical time influencing factors. The surgical time influencing factors were analyzed by stratified sampling. Results The surgeons- related factor was the highest influencing factor while the patients themselves-related factor was the lowest influencing factor in the 2-dimensional factors. The selected 38 1-dimensional factors could affect the operating time with their mean influencing value 2.45. The recognition of surgical time influencing factors was different in different operating rooms. Conclusion There are a variety of surgical time influencing factors. However,the surgeons-related factor is the highest influencing factor. The cognition of anesthesia-related factors and surgeons-related factors differs in different operating rooms.
