Sorry to hear about your dad.
You should start by asking to talk with the ward's occupational therapist as they will be involved with planning your father's discharge from hospital.
They should assess him on the ward,with input from nursing staff and judge whether or not in their view he could be looked after at home with a suitable 'package of care.'
If they think he could return home,and / or he expresses a keen desire to get home,they should at some stage carry out an assessment of his home environment to determine, if with suitable equipment in place,and suitable care package, he could be cared for at home.
For example he may need a hoist to be transferred from his bed into his wheelchair, and also onto a commode.
If this is the case 2 carers would be needed at least in the morning and again in the evening, and again for daytime toilet access.
(A live in carer would need back up in this situation)
If he has savings over around £22500 he may be paying for this care himself,but depending on father's local authority he may get a few weeks of free assessment period.
To find local care agencies and also homes go to www.cqc.org.uk and you can search by postcode for agencies and homes.
If it is felt instead that your father may need palliative care as he is suffering from a rapidly deteriorating illness he may be eligible for 'continuing care'funding, which comes from the NHS and is not means tested
Again the hospital and possibly the local social services team should be helping you through ths very difficult and confusing time.
Finally,depending on where your father lives expect to spend at least £80 to £120/day for live in care. A live in carer should be know how to wash and dress your father safely, and with dignity, together with preparing meals, prompting to take medication and light household tasks.
You also need to factor in additional costs such as the carer's food,but this depends on the agency you choose.
