Delays in discharging patients out of hospital after treatment could be costing the NHS in England £900m a year, an independent review has said.
Labour peer Lord Carter's report found nearly one in 10 beds was taken by someone medically fit to be released.
It said it was a "major problem" causing operations to be cancelled and resulting in the NHS paying private hospitals to see patients.
Union Unison said cuts to social care were a major cause of "bed-blocking".
Lord Carter identified the issue in a wider look at how £5bn could be saved by 2020.
His proposals called for better procurement and staff management, and savings to the drugs bill.
