Practice and exploration of 24-hour supervision model in personal protection supervision in a COVID-19 isolation ward

Multifactor Logistic Regression Analysis of Error Rate Factor Regression Coefficient Standard Error Wald Value P Value Exp(B) 95% Confidence Interval Upper Lower Profession 1.689 0.799 4.473 0.034 5.413 1.132 25.891 Discussion In this investigation, the error rate was significantly higher in the PPE doffing procedure than in the PPE donning procedure, which is consistent with the research by Zhang et al4 during SARS. [...]the standardized performance of PPE removal is very important.5 After implementation of the 24-hour supervision mode, the error rates of all steps in donning and doffing PPE significantly decreased. [...]hand hygiene plays an important role in safe donning and doffing.
