Deaf and Hard of Hearing Support at UHNM from UHNM NHS Trust on Vimeo.
Still gaps in their awareness but a really good effort. All deaf don't sign, don't lip read, and all HoH don't either, always ensure there is no blanket acceptance of need. I would have forseen issues with a glass screen and someone trying to communicate to me that way, as I don't carry a card, and I don't use sign either, of course, if you are in a queue and the counter staff haven't the time then it can quickly break down and become stressful.
I know most deaf would not attempt to go to a hospital unsupported so they are catered for mostly, it is the others with no defined effective communication as such who are elderly etc who present at POC. With no effective lip speakers on hand e.g, lip-reading is mostly zeroed as a format that can be used. Hearing aids can be zeroed too with no effective medical-patient loop. I think most would have resorted to writing things down. Personally, I take all relevant details with me in written form, and have few issues after. Of course, emergency admission is an absolute terror as everyone has to wing it. In those cases, deaf may refuse to go to a hospital unless supported first which can be very risky.
