Hi
@Ryn66
Usually, when a patient is discharged from hospital, the OT assesses what equipment is needed - such as a bed and mattress, a commode or a toilet frame, a walking frame etc, etc., in conjunction with the physiotherapist.
Usually the local authority health dept have a home rehabilitation dept - they come and assess the help needed for the patient and any family carer. They usually pay for the carers for the first 6 weeks. Then before the 6 weeks is up, they would want to carry out a financial assessment. If your dad, in his own name, has assets (excluding home where mum has a right to live) in excess of £23,250 then he would be regarded as a "self funder" and would be required to pay for his care. As already stated this is likely to be in the region of £20 - £30 per hour - so that 2 carers at a a time for 4 x 30mins visits per day = £80 to 120 per day. You should ask the care company appointed by the hospital/local authority what their charges are for a self funder. You can also research the charges from other care companies in your area.
If you dad has assets in his own name of less than £14,500 the local authority will pay for the care. If the assets in his name are between £14,500 and £23,250 then he has to make a contribution to the care cost and local authority make a contribution.
If the occupational therapist has recommended 2 cares for 4 visits per day, then it seems sensible to follow this, unless you believe, 3 visits per day could be coped with for your dad's needs. which is primary object.
2 carers per visit are always required when moving and/or lifting and/or turning a lying down patient is concerned, or using a hoist to lift a patient (eg from a bed to a chair).
You may well have to consider a residential care home as
@Banjomansmate has suggested.
Full time care always takes longer than you think. Every step takes longer to undertake than you can imagine, especially when the person with dementia cannot follow instructions or resists.
I do not know, but I would think that your 85 yr old mum with new hip would not be able to cope and it would be unfair to expect her to have the energy required. Caring is both physically and emotionally v tiring.
