Therapeutic nursing or unblocking beds? A randomised controlled trial of a post-acute intermediate care unit

To compare post-acute intermediate care in an inpatient nurse-led unit with conventional post-acute care on general medical wards of an acute hospital and to examine the model of care in a nurse-led unit.

Randomised controlled trial with six month follow up.

Urban teaching hospital and surrounding area, including nine community hospitals.

238 patients accepted for admission to nurse-led unit.

Care in nurse-led unit or usual post-acute care.

Patients' length of stay, functional status, subsequent move to more dependent living arrangement.

Inpatient length of stay was significantly longer in the nurse-led unit than in general medical wards (14.3 days longer (95% confidence interval 7.8 to 20.7)), but this difference became non-significant when transfers to community hospitals were included in the measure of initial length of stay (4.5 days longer (-3.6 to 12.5)). No differences were observed in mortality, functional status, or living arrangements at any time. Patients in the nurse-led unit received significantly fewer minor medical investigations and, after controlling for length of stay, significantly fewer major reviews, tests, or drug changes.

The nurse-led unit seemed to be a safe alternative to conventional management, but a full accounting of such units' place in the local continuum of care and the costs associated with acute hospitals managing post-acute patients is needed if nurse-led units are to become an effective part of the government's recent commitment to intermediate care.
