Where are you located? I have done some trainings in this area in Wisconsin, but it was 'pre masking' era, although the issue of face coverings was included in the training. We are working on something similar here again. May be able to collaborate, or put you in touch with someone who is involved in developing a new program in Wisconsin. We know that this issue is NOT commonly understood of by hospital personnel. The ADA covers a lot, but many do not related it to communication.
