Inspired by another thread about long ambulance waiting times (and we'll documented general concerns about the state of healthcare in the UK) it seems that a big factor is the way social care is decoupled from the NHS.
It means that people who are well enough to be discharged, but who require a card package to return home, or a place in a care facility are often "blocking" beds, causing a crunch at all other layers of the service.
How can we solve social care? How can we ensure older people are treated better and with more dignity? Do we need "convalescent homes", where they can continue to recover outside hospital in a less acute medical environment, acting as a super-hub for the services that will need to support them subsequently? Do we nest social care back under the NHS to ensure true cradle to grave care?
