Homeless Hospital Discharge Schemes that has brought together data on over 100,000 homeless people from across England to understand their health outcomes after discharge from hospital. Our study established that one in three people with experience of homeless admitted to hospital subsequently died from a health condition that our current medical knowledge and technology should have been able to prevent, if help was provided in a timely and appropriate manner. This research received extensive media coverage including an in depth piece on Channel 4 News and this work, and the corresponding economic evaluation has been used as the business case by several NHS trusts as the basis for commissioning intermediate care for people experiencing homelessness and informed the Mayor of London’s health vision for London.
