Improving the provision of supportive care for patients with Ebola is an important quality improvement initiative. We designed a simulated Ebola Treatment Unit (ETU) to assess performance and safety of healthcare workers (HCWs) performing tasks wearing personal protective equipment (PPE) in hot (35 °C, 60% relative humidity) or thermo-neutral (20 °C, 20% relative humidity) conditions. In this pilot phase to determine the feasibility of study procedures, HCWs in PPE were non-randomly allocated to hot or thermo-neutral conditions to perform peripheral intravenous (PIV) and midline catheter (MLC) insertion and endotracheal intubation (ETI) on mannequins. Eighteen HCWs (13 physicians, 4 nurses, 1 nurse practitioner; 2 with prior ETU experience; 10 in hot conditions) spent 69 (10) (mean (SD)) minutes in the simulated ETU. Mean (SD) task completion times were 16 (6) min for PIV insertion; 33 (5) min for MLC insertion; and 16 (8) min for ETI. Satisfactory task completion was numerically higher for physicians vs. nurses. Participants' blood pressure was similar, but heart rate was higher ( = 0.0005) post-simulation vs. baseline. Participants had a median (range) of 2.0 (0.0-10.0) minor PPE breaches, 2.0 (0.0-6.0) near-miss incidents, and 2.0 (0.0-6.0) health symptoms and concerns. There were eight health-assessment triggers in five participants, of whom four were in hot conditions. We terminated the simulation of two participants in hot conditions due to thermal discomfort. In summary, study tasks were suitable for physician participants, but they require redesign to match nurses' expertise for the subsequent randomized phase of the study. One-quarter of participants had a health-assessment trigger. This research model may be useful in future training and research regarding clinical care for patients with highly infectious pathogens in austere settings.
提高埃博拉患者的支持性护理水平是一项重要的质量改进举措。我们设计了一个模拟埃博拉治疗单元 (ETU),以评估医护人员 (HCWs) 在穿着个人防护设备 (PPE) 时执行任务的表现和安全性,这些任务是在炎热(35°C,60%相对湿度)或热中性(20°C,20%相对湿度)条件下进行的。在这个初步阶段,我们旨在确定研究程序的可行性,将穿着 PPE 的 HCWs 非随机分配到炎热或热中性条件下,以便在模拟 ETU 中对人体模型进行外周静脉 (PIV) 和中线导管 (MLC) 插入以及气管插管 (ETI)。18 名 HCWs(13 名医生,4 名护士,1 名护士从业者;2 名有 ETU 经验;10 名在炎热条件下)在模拟 ETU 中花费了 69(10)(平均值(SD))分钟。PIV 插入的平均(SD)任务完成时间为 16(6)分钟;MLC 插入的平均(SD)任务完成时间为 33(5)分钟;ETI 的平均(SD)任务完成时间为 16(8)分钟。与护士相比,医生完成任务的满意度更高。参与者的血压相似,但心率在模拟后更高(=0.0005)。参与者有中位数(范围)为 2.0(0.0-10.0)的轻微 PPE 破裂,2.0(0.0-6.0)的接近事故,2.0(0.0-6.0)的健康症状和担忧。在五名参与者中,有八名触发了健康评估,其中四名处于炎热环境中。由于热不适,我们终止了两名处于炎热环境中的参与者的模拟。总的来说,研究任务适合医生参与者,但需要重新设计以匹配护士的专业知识,以便在研究的随后随机阶段进行。四分之一的参与者触发了健康评估。这种研究模式可能对未来在恶劣环境中对高度传染性病原体患者的临床护理的培训和研究有用。
