Safe patient care in hospitals relies on teamwork. Transactive Memory Systems (TMS), are shared cognitive systems that have been linked to team performance in other domains, but have received limited attention in healthcare. This study investigated the role of TMS, psychological safety and interpersonal conflict in predicting team performance in hospital ward teams where team membership is dynamic and often loosely defined. Hospital staff ( = 106) in four wards completed a battery of instruments assessing team performance, TMS, psychological safety and interpersonal conflict. TMS was a weak predictor of team performance, but the relationship was mediated by psychological safety. Overall, team performance was predicted by high psychological safety, low interpersonal conflict and low reliance on team members' knowledge (i.e. TMS credibility). These findings suggest that, in hospital teams, TMS is not a strong predictor of team performance but team culture is critical to ensure the quality and safety of patient care. This study investigated the role of Transactive Memory Systems (TMS) and cultural factors in hospital team performance. Team performance was predicted by psychological safety, low interpersonal conflict and low reliance on team members' untested knowledge. This highlights the importance of a supportive and psychologically safe team culture for safe care in hospitals. : TMS: transactive memory systems; HCA: health care assistant.
医院中安全的患者护理依赖于团队合作。 传递记忆系统（TMS）是一种共享认知系统，已与其他领域的团队绩效相关联，但在医疗保健领域受到的关注有限。 本研究调查了 TMS、心理安全性和人际冲突在预测医院病房团队绩效中的作用，在病房团队中，团队成员是动态的，并且通常定义不明确。 四个病房的医院工作人员（ = 106）完成了一系列工具，评估团队绩效、TMS、心理安全性和人际冲突。 TMS 是团队绩效的一个较弱的预测因素，但这种关系是通过心理安全性来介导的。 总的来说，高心理安全性、低人际冲突和低依赖团队成员未经测试的知识（即 TMS 可信度）可以预测团队绩效。 这些发现表明，在医院团队中，TMS 不是团队绩效的有力预测因素，但团队文化对于确保患者护理的质量和安全至关重要。 本研究调查了传递记忆系统（TMS）和文化因素在医院团队绩效中的作用。 心理安全性、低人际冲突和低依赖团队成员未经测试的知识可以预测团队绩效。 这突出了支持性和心理安全的团队文化对于医院安全护理的重要性。
