PURPOSE: The lack of training in personal protective equipment (PPE) donning and doffing is hindering the current fight against the COVID-19 worldwide. In order to enable medical staff to learn how to don and doff PPE faster and more effectively, we compared two training methods of PPE donning and doffing. METHODS: Participants in this study were 48 health care workers randomly divided into two groups. Group A watched a 10-minute demonstration (demo) video four times, while Group B watched the same 10-minute demo video twice and then watched a 10-minute live demo twice. The 40-minute learning time was the same for both groups. A 29-step examination was held after the training was completed. The examination scores of Groups A and B were recorded according to a checklist containing PPE donning and doffing steps . The time spent by the participants on PPE donning and doffing, their satisfaction with the training, and their confidence in donning and doffing PPE accurately were analyzed. RESULTS: The average score of Group B was higher than that Group A, with a mean (SD) of 94.92 (1.72) vs 86.63 (6.34), respectively (P<0.001). The average time spent by Group B was shorter than that spent by Group A, with a mean (SD) of 17.67 (1.01) vs 21.75 (1.82), respectively (P<0.001). The satisfaction and confidence of Group B were higher than those of Group A (P<0.001). CONCLUSION: Compared with repeated video display, combined video display and live demonstration are more suitable training methods for donning and doffing PPE.
