Figures published yesterday show more than 90,000 cases of corridor care were recorded in English NHS hospitals in May - an average of 3,000 per day.
Katie Reade, Head of Policy & Public Affairs at Hospice UK said:
"A third of patients in hospital are in their last year of life, meaning some people with palliative care needs will undoubtedly be among those receiving corridor care.
"These figures raise the alarming prospect of people potentially dying in corridors, without adequate pain relief, privacy, or access to the care they need.
"Many people receiving corridor care today could have avoided admission to hospital if they had received earlier access to palliative and end of life care.
"Hospices are part of the solution. They ease pressure on an overstretched NHS by preventing avoidable hospital admissions, supporting earlier discharge and reducing distressing visits to A&E.
"The Government has committed to more care closer to home, but hospice services are shrinking when they should be expanding. Nearly six in ten hospices have made or are considering frontline service cuts, 380 desperately needed hospice beds are out of use, and specialist community visits fell by 20% last year.
"Hospices are underfunded and underutilised. Only around 40% of the cost of their essential care is covered by government funding, with the rest reliant on fundraising and charitable donations. This broken funding model needs to change."
