非心脏手术的团队熟悉和围手术期结果

2026年8月23日更新者：Peng Zhendan、Zhongda Hospital

团队熟悉对手术结果和患者安全性在非心脏手术中的影响

这项回顾性观察性研究的目的是量化团队协作对非心脏手术团队中手术室和患者安全结果的工作效率的影响。主要目的是回答：

在手术期间/之后，团队协作如何影响手术室和患者安全结果的工作效率？数据将从医院电子病历信息系统中获得，参与者已经完成了所有计划的手术。

详细说明

这项研究旨在揭示团队合作在外科手术中的关键作用。首先，通过计算手术团队内的协作程度，我们量化了团队成员之间的互动，沟通和信任，并随后分析了这种协作对手术团队工作效率指标的影响，包括麻醉前准备时间，麻醉时间和操作时间和操作时间，以确定最佳实践。其次，它分析了手术团队之间的合作程度如何影响患者安全指标，例如术中失血，计划外次级手术的发生率和院内死亡率，从而揭示了团队工作对患者安全的直接或间接贡献。还分析了手术团队规模，性别组成和转移模式对工作效率和患者安全指标的影响。

研究衡量的是什么？

主要结果指标

结果测量	措施说明	大体时间
Operating Room Team Efficiency 大体时间：During the index surgical procedure, assessed up to 24 hours	Operating room team efficiency is assessed by three workflow time intervals: pre-anesthesia preparation time, defined as the interval from patient arrival in the operating room to anesthesia initiation; anesthesia induction time, defined as the interval from anesthesia initiation to surgery start; surgical duration, defined as the interval from surgery start to surgery completion. All time intervals are measured in minutes based on timestamps recorded in the anesthesia information management system.	During the index surgical procedure, assessed up to 24 hours

次要结果测量

结果测量	措施说明	大体时间
Estimated Intraoperative Blood Loss 大体时间：During the index surgical procedure, assessed up to 24 hours	Total estimated blood loss during surgery, recorded in milliliters (mL) from anesthesia and surgical records.	During the index surgical procedure, assessed up to 24 hours
Duration of Post-Anesthesia Care Unit (PACU) Stay 大体时间：From transfer from the operating room to the PACU until transfer from the PACU to the ward after the index surgery, assessed up to 12 hours	The duration of PACU stay, defined as the time interval from admission to discharge from the post-anesthesia care unit, recorded in minutes.	From transfer from the operating room to the PACU until transfer from the PACU to the ward after the index surgery, assessed up to 12 hours
Postoperative ICU Admission 大体时间：From completion of the index surgical procedure until hospital discharge, assessed up to 90 days	Whether the participant was admitted to the intensive care unit after the index surgery (yes/no), including direct transfer from the operating room to the ICU without PACU recovery, identified from postoperative medical records.	From completion of the index surgical procedure until hospital discharge, assessed up to 90 days
Duration of ICU Stay 大体时间：From postoperative ICU admission until ICU discharge or transfer to the ward during the index hospitalization (recorded as 0 days if no ICU admission), assessed up to 90 days	Length of postoperative ICU stay in days. Participants not admitted to the ICU are recorded as 0 days; for those admitted (including direct transfer from the operating room to the ICU), duration is measured from ICU admission until ICU discharge or transfer to the ward.	From postoperative ICU admission until ICU discharge or transfer to the ward during the index hospitalization (recorded as 0 days if no ICU admission), assessed up to 90 days
Unplanned Secondary Surgery Within 31 Days After Surgery 大体时间：From the day of the index surgical procedure, assessed up to 31 days	Occurrence of an unplanned secondary surgical procedure within 31 days after the index surgery, identified from hospital surgical records.	From the day of the index surgical procedure, assessed up to 31 days
In-Hospital Mortality 大体时间：From the day of the index surgical procedure until hospital discharge, assessed up to 90 days	Death occurring during the index hospitalization after surgery, identified from hospital medical records.	From the day of the index surgical procedure until hospital discharge, assessed up to 90 days
Unplanned Hospital Readmission Within 31 Days After Surgery 大体时间：From the day of the index surgical procedure, assessed up to 31 days	Occurrence of an unplanned hospital readmission within 31 days after the index surgical procedure, defined as an unexpected inpatient admission after discharge from the index hospitalization and identified from hospital medical records.	From the day of the index surgical procedure, assessed up to 31 days
Length of Hospital Stay 大体时间：From hospital admission until hospital discharge for the index surgical procedure, assessed up to 90 days	Total duration of hospitalization, measured in days, from hospital admission to discharge after the index surgical procedure.	From hospital admission until hospital discharge for the index surgical procedure, assessed up to 90 days
Total Hospitalization Cost 大体时间：From hospital admission until hospital discharge for the index surgical procedure, assessed up to 90 days	Total hospitalization expenses associated with the index surgical procedure, recorded in Chinese Yuan (CNY) based on hospital billing records.	From hospital admission until hospital discharge for the index surgical procedure, assessed up to 90 days
