Evidence-based out-of-hours hospital medicine.

Out-of-hours (OOH) hospital ward cover is generally provided by junior doctors and is typified by heavy workloads, reduced staff numbers and various non-urgent nurse-initiated requests. The present inefficiencies and management problems with the OOH service are reflected by the high number of quality improvement projects recently published. In this narrative review, five common situations peculiar to the OOH general ward setting are discussed with reference to potential areas of inefficiency and unnecessary management steps: (1) prescription of hypnotics and sedatives; (2) overnight fluid therapy; (3) fever; (4) overnight hypotension and (5) chasing outstanding routine diagnostic tests.
