Plans have been put forward to cut hospital services in two-thirds of England, a BBC analysis shows.
The proposals have been put forward by local NHS bosses as part of a national programme to transform the health service and save money.
They include everything from full closures of hospitals to cutting some specialist services such as accident and emergency and stroke care.
Ministers argue patients will receive better care in the community.
But a review of the plans by the King's Fund think tank warned they were not always credible because there were not enough services outside of hospitals.
It warned GPs, district nursing and council care services were already "feeling the strain" and could not currently cope with an increase in workload.
This simply cannot be allowed to happen. The 'community' cannot cope and it means more and more people are going to miss out on treatment ands suffer from neglect. I've been a Tory for most of my life but this closing of hospitals under the guise of improving patient services is an all thought out policy.
May needs to forget the austerity as far as the NHS is concerned and either borrow more money or increase taxes to ensure that it and social care are sufficiently funded.
