When my dd was doing caring in the community, the most common situation was a family member would let them in, if that wasn't possible, key safe.
Its not just feeding, its cleaning, washing up, dressing and washing the client, helping with medication, changing stoma's.
People who can heat up a meal and answer the door, will not be getting state provided care.
The issue now is that hospitals cannot get carers, so in Cornwall, the district hospital is having to provide them from hospital staff i.e. nurses/hca's, leading to further staff shortages.
