Comparing Written Programs and Self-reported Respiratory Protection Practices in Acute Care Hospitals

Margaret Sietsema, Lorraine M. Conroy and Lisa M. Brosseau
5. While hospitals were often lacking important details in their written respiratory protection programs, they appeared to be following many of the requirements of the OSHA respiratory protection standard. What do the authors hypothesize is the reason for this?

6. While many hospital programs did not describe a risk assessment and respirator selection strategy, those programs that did so were primarily focused on which organisms? (check all that apply)
