No studies were identified in this review for the safety of different levels of wear compliance. One study was analyzed for the repeated donning and doffing of respiratory protection for healthcare workers. Authors found that multiple donning and doffing processes have a significant impact on protective capability and a maximum of five repeated processes should be instituted as the maximum acceptable. No systematic reviews or health technology assessments were identified for either of these questions. The guidelines that were identified were of excellent quality and contained well represented pictorial depiction for proper donning/doffing techniques though they did suffer from a lack of defined study inclusion criteria.
