Both the GP and social care have impacted - one on the way in, the other on the way out.
Shorter GP opening has resulted in more going in, but lack of social care places means people, esp elderly, aren't able to leave despite not needing the same level of care as provided in hospital. Hospitals have become bottlenecks.
I think one thing we should see is MP's and high ranking officials having to use the NHS for healthcare (without preferential treatment) and not private insurance etc meaning many don't experience the true problems in the service. It doesn't affect them to the same extent so aren't as bothered about it other than how it affects voting for them. Put them in the problem and you'd soon see an attempt to fix it.
