Personal protective equipment during the COVID-19 pandemic (Letter #1) George D. Shorten, MD, PhD

To the Editor, Lockhart et al. have reviewed the importance and use of personal protective equipment (PPE) for anaesthesiologists and other airway managers.1 They point out that ‘‘PPE donning and doffing requires education and practice prior to their use during patient care’’, going on to state that ‘‘ the more unfamiliar staff is with PPE, the more likely they will incorrectly don and doff it’’. Weissman et al.2 have expressed the need for fundamental research to inform PPE recommendations, particularly in the setting of tracheal intubation. They cite the recent work of Feldman et al.3 who showed that, in a simulated setting, currently recommended PPE may not prevent exposure of those who perform tracheal intubation. One critical aspect of the efficacy of PPE in protecting healthcare workers (HCWs) is the manner in which donning is performed. A closer examination of training in donning and doffing PPE is warranted. During the coronavirus disease pandemic, the circumstances under which donning and doffing of PPE is being learned, trained, and subsequently performed may be suboptimal. Although no overview exists of the training practices for donning and doffing PPE, it is likely that it is less than ideal.

Ideally, in designing a training program for a new procedure, one would: 1) share a description of the procedure with ‘‘trainees’’ that contains unambiguous definitions of each step, and common and critical errors; 2) apply a pre-training preparation standard; 3) provide real-world materials (e.g., PPE) for repeated deliberate practice; 4) provide multiple training sessions based on performance; and 5) undertake an ‘‘exit’’ assessment. The ‘‘graduate trainee’’ would then transfer their newly acquired skills into the real world with experienced supervision. Of course, one might argue that the current pandemic requires that prompt action is required during which perfect is the enemy of good. In fact, scientifically rigorous training methodology exists which ensures that a newly learned procedure is performed competently. The discipline of anesthesiology has been at the forefront of training to a pre-defined level of competency.4 Proficiencybased progression and other forms of metrics-based training decrease the incidence of errors amongst novice practitioners and the evidence of its consistent efficacy is particularly strong for procedural skills.5 It is possible that the difficulties in donning and doffing PPE are underestimated. Seal-testing a face mask and minimizing the risk of fogging googles are particularly amenable to error. The key resource for such training (characteris
