The Anesthesiology Control Tower (ACT) for operating rooms (ORs) remotely assesses the progress of surgeries and provides real-time perioperative risk alerts, communicating risk mitigation recommendations to bedside clinicians. We aim to identify and map ACT-OR nonroutine events (NREs)-risk-inducing or risk-mitigating workflow deviations-and ascertain ACT's impact on clinical workflow and patient safety.
We used ethnographic methods including shadowing ACT and OR clinicians during 83 surgeries, artifact collection, chart reviews for decision alerts sent to the OR, and 10 clinician interviews. We used hybrid thematic analysis informed by a human-factors systems-oriented approach to assess ACT's role and impact on safety, conducting content analysis to assess NREs.
Across 83 cases, 469 risk alerts were triggered, and the ACT sent 280 care recommendations to the OR. 135 NREs were observed. Critical factors facilitating ACT's role in supporting patient safety included providing backup support and offering a fresh-eye perspective on OR decisions. Factors impeding ACT included message timing and ACT and OR clinician cognitive lapses. Suggestions for improvement included tailoring ACT message content (structure, timing, presentation) and incorporating predictive analytics for advanced planning.
ACT served as a safety net with remote surveillance features and as a learning healthcare system with feedback/auditing features. Supporting strategies include adaptive coordination and harnessing clinician/patient support to improve ACT's sustainability. Study insights inform future intraoperative telemedicine design considerations to mitigate safety risks.
Incorporating similar remote technology enhancement into routine perioperative care could markedly improve safety and quality for millions of surgical patients.
麻醉学控制塔(ACT)可远程评估手术室(OR)手术进展情况,并提供实时围手术期风险警报,向床边临床医生传达风险缓解建议。我们旨在确定和映射 ACT-OR 非例行事件(NRE)——引起风险或降低风险的工作流程偏差——并确定 ACT 对临床工作流程和患者安全的影响。
我们使用人种学方法,包括在 83 次手术中观察 ACT 和 OR 临床医生、收集文物、审查发送到 OR 的决策警报图表以及进行 10 次临床医生访谈。我们使用混合主题分析方法,该方法受以人为中心的系统方法的启发,以评估 ACT 在安全性方面的作用和影响,进行内容分析以评估 NRE。
在 83 例病例中,触发了 469 个风险警报,ACT 向 OR 发送了 280 条护理建议。观察到 135 个 NRE。促进 ACT 支持患者安全的关键因素包括提供后备支持和为 OR 决策提供新的视角。阻碍 ACT 的因素包括消息的时间安排以及 ACT 和 OR 临床医生的认知失误。改进建议包括调整 ACT 消息的内容(结构、时间、呈现方式)并纳入预测分析以进行高级规划。
ACT 充当具有远程监控功能的安全网,并且是具有反馈/审核功能的学习型医疗保健系统。支持策略包括自适应协调和利用临床医生/患者支持来提高 ACT 的可持续性。研究结果为未来术中远程医疗设计考虑因素提供了信息,以减轻安全风险。
将类似的远程技术增强功能纳入常规围手术期护理中,可以显著提高数百万手术患者的安全性和质量。
