I can not wear a paper or cloth mask, because of allergies to dust and mites. I wear a full face shield. Several times this year I have had a hospital admin cancel doctor appoints and testing in this hospital because of the shield. This is very troubling as I have Stomach Cancer and she has denied me treatment. I believe she has my registration information flagged in the computer system and is notified each time I appear at the hospital. It is always the same woman and she will not ID herself to me. Last Friday was the most recent event. There are doctors with specialty clinics within this hospital. This woman has cost me my Family doctor because of her unwillingness to accept the fully approved full face shield. All the other hospitals and clinics and doctors accept this shield, and the dr. I was to see last Friday knew in advance that I would be wearing the shield and his MA and nurse accepted that shield, it is this admin that has a problem wit h it.
