FINANCE: The introduction of night time confinement for patients at Ashworth Hospital could save Mersey Care Trust £3.5m by 2015.

The trust wants to roll out the policy by March next year, which would allow it to reduce the number of staff on duty overnight from 73 to 36.

A change to NHS safety and security directions for high secure hospitals has meant that night time confinement is allowable and the trust has already invested in doors which allow patients to be observed in preparation for the move.
