Abstract
A universal community testing programme (UCTP) was initiated by the government of the Hong Kong Special Administrative Region of the People's Republic of China, as part of a territory-wide initiative to enhance the control of the coronavirus disease (COVID-19) pandemic, to facilitate the early identification of asymptomatic patients in the community-transmission chain. The authors (who were also engaged in this programme) observed that, at the end of their 6-hour shift, most of the HCPs sustained medical device-related pressure injuries (MDRPI), frequently on their faces, over the bridge of their nose, the upper cheeks, above the ears, lower jaws, and chin that caused pain and erythema. In this study, our team examined whether two different types of dressing (light silicone foam dressing and soft silicone perforated tape dressing) applied on the anatomical locations (including the bridge of the nose, upper cheek, above the ears, and lower jaw) would enable the wearer to pass the quantitative respirator fit testing that was conducted using a PortaCount Pro+ Respirator Fit Tester 8038. We also investigated if any skin reactions occurred after the participants worn the respirator with our applied dressing materials for 240 minutes in a safe laboratory setting. Lastly, we collected the qualitative feedback concerning how the participants felt about the performance of our dressing materials in preventing MDRPI associated with the prolonged use of tight-fitting FFRs. A small convenience sample of HCPs (n = 24) who participated in the UCTP was recruited. We randomly selected 12 participants for one type of dressing, and the rest for the second type of dressing. Quantitative fit testing showed an adequate seal of the respirators with the use of both types of thin dressings that were available in the clinical settings. All of the participants except one tolerated the dressings for prolonged use without any report of adverse skin reactions. Our findings may move a step forward in assisting the process of developing feasible pre-emptive skincare practice guidelines to reduce MDRPI during the prolonged use of nanofiber bacterial surgical respirators.
