UNASSIGNED: Among a cohort of 183 HCP, we prospectively examined how HCP rated EHMR tolerability using the Respirator Comfort, Wearing Experience, and Function Instrument (R-COMFI) questionnaire at Study Week 2 and Week 10. At the completion of the study (Week-12), HCP compared EHMR comfort with their prior N95 FFR use. Overall R-COMFI scores and three subscales (comfort, wear experience, and function) were examined as well as individual item scores.
UNASSIGNED: The HCP reported an improved overall R-COMFI score (lower score more favorable, 30.0 vs. 28.7/47, respectively) from Week 2 to Week 10. Many individual item scores improved or remained low over this period, except difficulty communicating with patients and coworkers. The overall R-COMFI scores for the EHMR were more favorable than for the N95 FFR (33.7 vs. 37.4, respectively), with a large proportion of workers indicating their perception that EHMR fit better, provided better protection, and they preferred to wear it in pandemic conditions compared with the N95 FFR.
UNASSIGNED: Findings suggest that the EHMR is a feasible respiratory protection device with respect to tolerance. EHMRs can be considered as a possible alternative to the N95 FFR in the health care setting. Future work is needed in the EHMR design to improve communication.
■在183名HCP中,我们前瞻性地检查了HCP如何使用呼吸器舒适度评估EHMR耐受性,佩戴经验,和功能仪器(R-COMFI)问卷在研究第2周和第10周。在研究完成时(第12周),HCP将EHMR舒适度与之前使用的N95FFR进行了比较。总体R-COMFI评分和三个分量表(舒适度,佩戴经验,和功能)进行了检查以及个别项目得分。
■HCP报告总体R-COMFI得分有所改善(得分越低越好,30.0vs.分别为28.7/47)从第2周到第10周。在此期间,许多个别项目得分提高或保持较低,除了与患者和同事沟通困难。EHMR的总体R-COMFI得分比N95FFR更有利(33.7vs.分别为37.4),很大一部分工人表示他们认为EHMR更适合,提供更好的保护,与N95FFR相比,他们更喜欢在大流行条件下佩戴它。
■研究结果表明,就耐受性而言,EHMR是一种可行的呼吸保护装置。EHMR可以被认为是医疗保健环境中N95FFR的可能替代方案。在EHMR设计中需要未来的工作来改善通信。
