During COVID-19 pandemic, a shortage of surgical masks (Mask) and respirators (Resp) was experienced worldwide. We aimed to assess its pattern of use, adverse effects and user errors by Portuguese health care professionals (HCP).
A cross-sectional study was conducted through snowball convenience sample, collected by email/ social media to health care organizations. Participants answered an online anonymous survey in March 2021.
Mean age of 3052 respondents was 42.1 years old, 83.6% were female and 77.8% provided direct health care to COVID-19 patients. Mean time of use per shift was 6-8 hours in 40.8% of the participants. 28.0% reported never changing it during their shift. Resp use (vs Mask) was more associated with discomfort (58.2% vs 26.8%), affecting task performance (41.5 vs 18.9%) and communication (55.0 vs 40.9%), dyspnea (36.0 vs 14.4%), skin rash (37.5 vs 19.4%) and headache (37.5 vs 19.4%). Frequent user errors included touching the front while in use (70.1% Mask vs 66.3% Resp) and omitting hand hygiene before (61.8% Mask vs 55.0% Resp) or after use (61.3% Mask vs 57.0% Resp). Average number of errors was higher for Mask (4.3), than for Resp (3.2) (all: P < .001).
Most HCP admitted an extended use of Mask/ Resp. Resp were more prone to adverse effects and Mask more prone to errors. Strategies to reinforce good practices should be considered.
在 COVID-19 大流行期间，全球范围内出现了外科口罩（口罩）和呼吸器（呼吸器）短缺的情况。我们旨在评估葡萄牙卫生保健专业人员（HCP）对其使用模式、不良反应和使用者错误的评估。
通过雪球便利样本进行了一项横断面研究，通过电子邮件/社交媒体收集卫生保健组织的样本。参与者于 2021 年 3 月回答了在线匿名调查。
3052 名受访者的平均年龄为 42.1 岁，83.6%为女性，77.8%为 COVID-19 患者提供直接医疗服务。40.8%的参与者每班次使用时间为 6-8 小时。28.0%的人报告在轮班期间从未更换过口罩。与口罩相比，呼吸器的使用（与口罩相比）更容易引起不适（58.2%比 26.8%），影响任务表现（41.5%比 18.9%）和沟通（55.0%比 40.9%），呼吸困难（36.0%比 14.4%），皮疹（37.5%比 19.4%）和头痛（37.5%比 19.4%）。频繁的使用者错误包括在使用时触摸口罩的前面（口罩为 70.1%，呼吸器为 66.3%），以及在使用前（口罩为 61.8%，呼吸器为 55.0%）或使用后（口罩为 61.3%，呼吸器为 57.0%）不进行手部卫生。口罩的错误平均数量（4.3）高于呼吸器（3.2）（均 P<.001）。
大多数 HCP 承认口罩/呼吸器的使用时间延长。呼吸器更容易出现不良反应，口罩更容易出现错误。应考虑采取策略加强良好操作。
