Can you get anyone to go into his house and email you photos for you to show social workers?
Speak to the social worker at the hospital using words like "vulnerable" and "unsafe discharge". Also phone the Local Authority adult social services, they should have a help line number, and explain that the hospital is proposing to discharge a vulnerable adult back into the community. You believe his home situation needs to be assessed before this happens. Follow this with a clear email outlining your concerns, attaching photos, and giving reasons why you feel he is "at risk".
It feels bad shopping a family member to Social Services but they need to be involved at some point with all the oldies who are struggling to cope on their own. They can be helpful and a properly flagged file should help prevent unsafe discharges in the future.
(My own experience was three years ago when at about this time the hospital suddenly announced they had changed their plans and would discharge my immobile mother on Christmas Eve to an empty flat in an empty block - the rest were second homes - despite, as we later discovered, hospital notes saying she was very confused. With, as it appears, no conversation with Social Services. Luckily we had the money to put her in expensive convalescent care whilst we found a solution, but as I went up the steep learning curve I realised it was crucial that she became known to Social Services and properly assessed.)
My mother had been hoarding. Now she is in sheltered housing she does not. I would be tempted to ask the hospital or the GP to look at possible:
- Dementia. Each time my mother went to the supermarket she would buy basics like washing powder and toothpaste forgetting she had cupboards full at home. Looking back this would have been a very early sign her memory was failing.
- Depression. My mother was clearly very lonely after my father died and probably aware of her failing memory, yet determined to remain "independent". There are a number of mail order firms who seem to target the elderly, promising good health via over priced vitamins, or the chance to be a perfect 60s style housewife/hostess via all sorts of weird kitchen equipment (chicken shears anyone?) What is your dad hoarding and what does it represent?
A diagnosis for either might open te way to some treatment, and also help lever in SS/care support.
A personal tip is to try to keep a distance and perspective. Less can be more. If you have to go down and I would wait till you have a clearer idea of what the optins are, collect several tasks and have clear objectives. For example meet with SS, arrange a key safe, get your dad to sign a POA or get third party access on his bank account, divvy up tasks with your brother (I was able to stuff all the paperwork into a suitcase and sort it out at home, really important as knowing how much money there was helped decision making, plus she had been very vulnerable to fraud) etc. If your husband can get a couple of days off work try to stay somewhere nice (if you suggest you might be a regular visitor you can get very cheap out of season rates) and do some nice family things along with the grotty. I found the clearing of someone else's life, and dealing with a mother who was clearly very frightened, emotionally exhausting. I got a lot more done when my husband was able to come down.
