Overnight calls in primary care: randomised controlled trial of management using nurse telephone consultation

Abstract
This study was an adjunct to a randomised controlled trial in a 55 member general practice cooperative serving 97 000 patients in Wiltshire. The design has been described.1 The night nurse telephone consultation service ran over two two-week periods (15-28 October 1997 and 12-25 November 1997) from 11.15 pm until 8 am. Outcome measures were as used in the main trial with one addition: the number of patients attending daytime surgery within three days of a call.1 One of us (FT) visited each surgery to extract details of attendances from patient records.
