Estimation Formula for Preparation Time of Anesthesia Induction Surgery accounting for Department Factors in Optimal Surgery Schedule Management

The clinical information (department, anesthesia factor, operation factor) was acquired from the medical records. The time at which the patient entered the operating room, time at which anesthesia was administered, and time at which operation was started were obtained. The anesthesia factors were as follows: type of anesthesia, insertion of epidural catheters, insertion of peripheral venous catheter (1st), insertion of peripheral venous catheter (2nd), insertion of arterial catheter insertion, and insertion of central venous catheter. The surgical factors were use of endoscope, surgery position, use of preoperative mobile biplane X-ray imaging, use of preoperative ultrasound diagnostic device, and use of preoperative surgical navigation systems. To address bias sources, researchers audited the accuracy of data input.

本研究从医疗病历中提取临床相关信息，涵盖科室、麻醉相关因素与手术相关因素。研究采集了患者进入手术室时间、麻醉实施时间以及手术开始时间。麻醉相关因素包括：麻醉方式、硬膜外导管置入、首次外周静脉导管置入、二次外周静脉导管置入、动脉导管置入以及中心静脉导管置入。手术相关因素包括：内窥镜使用情况、手术体位、术前移动式双向X射线成像设备使用情况、术前超声诊断设备使用情况以及术前手术导航系统使用情况。为控制偏倚来源，研究人员对数据录入的准确性进行了审核校验。
