Ditto the concerns above. More specifically, my concern would be about personal care - particularly if I were to become frail or infirm. Certainly in my neck of the woods, care homes tend to assign female carers to female patients and male carers to male patients, particularly if the patient needs to get naked or partially naked for anything (e.g. toilet, bathing, dressing, medical check-ups etc.).
How will they decide which type of carer is appropriate for a trans patient? A transphobic manager may well assign someone of our birth sex to care for us, which in my case would be hugely inappropriate and a violation of my person - and I daresay many here would feel the same way. And that's just us binary folk: how would they decide who to assign to a non-binary person?
Either way, would those carers respect us? Would they mock, bully or abuse us for perhaps having non-standard body parts? Once I've had bottom surgery I'll need the occasional checkup and replacement of the equipment involved, and I'll also need occasional checkups for some other problems I have acquired as a result of having my kids. Would they be able to keep an eye on these things? And could they remain professional whilst doing so?
Have they considered the sort of health care we may continue to need as we age, such as (perhaps) prostate checks for trans women and cervical smears for trans men? I've had some nasty dealings with health care 'professionals' whose bedside manner and lack of tact has been very difficult for me to cope with. I dread to encounter the same whilst in an even more vulnerable position.
Good grief... what if I were to get some form of dementia, regressing to an earlier state of my life, and forget that I'd transitioned? This will almost certainly happen to some of us. Have care homes thought of this eventuality? How will it be managed? Will the patient be consulted about their wishes (if this is possible)? Is it possible that a transphobic care home manager will force us to live in a gender-inappropriate way if that happens?
If any of the above were to happen, I'd be booking a one-way ticket to Switzerland.
