As far as I understand, it this isn't about community care. It's care for people who would otherwise be in hospital. That would apply to some people with ME/CFS, but not many.
Yes, that is what I'm thinking about. People with ME/CFS who are at risk of hospital admission, probably primarily due to feeding/weight maintenance issues. People with ME/CFS who would like to be discharged from hospital, perhaps with a feeding tube, but so far haven't been allowed to be. It seemed as though there was a gap that Maeve and others fell through.I imagine this as being potentially most relevant in v severe and preventative dietary support, but that is not something I know enough about to make constructive suggestions.
I don't think you would need to restrict the service to a particular sub-national geographical location, or, at least, not a very specific one. District nurses/support workers might still call in on the patient, but there would be some management/support for those nurses from the ME/CFS hospital in the home service.
I note that the Health and Social Care Delivery Research group has two funding calls out at the moment. One is on the Hospital at home concept, one is much more general about health and social care delivery innovation (closes 29 July). That considerably opens up possibilities. With Maeve's inquest having made it clear that there are big problems, and the delivery plan soon to come, I think funding something around providing better care and support to people with severe and very severe ME/CFS and their families might be seen as attractive.
I think if there was a group of people or an organisation interested in trying something different in the UK, it could well be worth talking with the team there to work out exactly what would be fundable.
