We've got exactly this at the moment.
MIL is 74, seriously disabled and cannot speak at all.
She had a fall on Monday, she's in hospital. No-one can visit.
She can't use a phone to talk, can't text or type. To communicate, we need to physically be with her.
The hospital are struggling because they just don't know how to talk to her. She can't get help or ask for anything.
Oh, and we've had one update since she was admitted, on Monday evening. We asked for contact today - still waiting. Apparently, this morning they'd tried but they'd been ringing her home phone, despite being clearly told my mobile was primary contact. She could be dead, and we'd be none the wiser.
It's ridiculous and unfair to everyone, including the staff. They need us there to be able to offer her the best care - they said as much Monday
