目的 探讨以跨专业协作团队发展理论为框架的早期活动多学科协作模式在ICU机械通气患者中的实施效果。 方法 采用类实验研究法，选取2023年7月—2024年2月在重庆市某三级甲等医院ICU接受机械通气治疗的危重患者作为研究对象，按照入院时间先后分为试验组54例、对照组56例。试验组实施基于跨专业协作团队发展理论的早期活动多学科协作模式，对照组实施常规早期活动方案，比较干预前后多学科团队成员协作水平、患者早期活动开展率、ICU期间累计活动时长、不良事件发生率、首次主动活动时间、离床活动率、机械通气时间的组间差异。 结果 试验组多学科成员团队协作水平提高，实施后和实施前分别为（3.72±0.50）分和（3.32±0.71）分（P<0.01）；试验组患者早期活动开展率提高，试验组和对照组分别为48.21%和35.22%（P<0.05）；试验组患者离床活动率提升，试验组和对照组分别为48.1%和7.1%（P<0.01）。患者ICU住院期间的累计活动时长增加（P<0.05），机械通气时间缩短（P<0.05）；两组患者活动期间均无重大不良事件发生，首次主动活动时间差异无统计学意义（P>0.05）。 结论 基于跨专业协作团队发展理论的早期活动多学科协作模式可提升多学科团队成员的协作水平，促进机械通气患者早期活动的开展，提升活动效率。

Objective To evaluate the implementation effect of an early activity multidisciplinary collaboration model based on the framework of the interprofessional collaborative team development theory in ICU mechanically ventilated patients. Methods Critically ill patients who received mechanical ventilation treatment in the Department of Intensive Care Medicine of a tertiary-level A hospital from July 2023 to February 2024 were selected as the study subjects using quasi-experiment research method，and were divided into 54 cases in the experimental group and 56 cases in the control group according to the sequence of admission time. The experimental group implemented the multidisciplinary cooperation mode of early activity based on the interprofessional collaborative team development theory，and the control group implemented the routine early activity program. The differences between the groups before and after intervention were compared in the level of cooperation of multidisciplinary team members，the rate of early activity among patients，the cumulative activity duration during ICU，the incidence of adverse events，the time of first active activity，the rate of out-of-bed activity，and the length of mechanical ventilation. Results The team cooperation level of multi-disciplinary members in experimental group was improved from（3.32±0.71） points to（3.72±0.50） points（P<0.01）. The early activity rate of experimental group was increased （The rates in experimental and control group were 48.21% and 35.22%）（P<0.05）The out-of-bed activity rate of experimental group was increased（The rates in experimental and control group were 48.1% and 7.1%）（P<0.01）. The cumulative activity time of patients during ICU stay was increased（P<0.05），and the length of mechanical ventilation was shortened（P<0.05）. There were no significant adverse events between the two groups during the activity period，and there was no significant difference in the time of the first active activity（P>0.05）. Conclusion The multidisciplinary collaboration model of early activity based on the theory of interprofessional collaborative team development may improve the cooperation level of multidisciplinary team members，promote the early activity of mechanical ventilation patients，and improve the efficiency of activity.
