Effect on hospital attendance rates of giving patients a copy of their referral letter: randomised controlled trial

Abstract

Objectives: To investigate whether sending patients a copy of their referral letter can reduce non-attendance at outpatient departments. Design: Blinded randomised controlled trial. Setting: 13 general practices in Exeter, Devon. Subjects: 2078 new consultant referrals from 26 doctors. Main outcome measures: Non-attendance at outpatient departments. Results: The doctors excluded 117 (5.6%) referrals, and 100 (4.8%) received no appointment. Attendance data were available for 1857 of the 1861 patients sent an appointment (99.8%). The receipt of a copy letter had no effect on the non-attendance rate: copy 50/912 (5.5%) versus control 50/945 (5.3%). Conclusion: Copy letters are ineffective in reducing non-attendance at outpatient departments.
