Use of mobile telephone short message service (SMS) as a reminder: the effect on patient attendance.
OBJECTIVE
To evaluate the operational and financial efficacy of sending short message service (SMS) mobile telephone text message to patients with outpatient clinic appointments.


METHODS
Patients scheduled to attend an outpatient appointment at the Dept. Paediatric Dentistry, Edinburgh Dental Institute, Scotland, during October 2007 and who had mobile telephone contact details were sent a reminder SMS text 24hr prior to their appointment. An historical control group were selected from October 2006.


RESULTS
Data were available for 276 (F: 146; M: 130) and 433 (F: 228; M: 205) patient attendances during 2006 and 2007 respectively. Overall, 10.4% and 23.9% of the SMS and historical group failed to attend (FTA) respectively and the difference was statistically significant (Chi Square = 6.95, p = 0.008, 1 d.f). There was a reduction in the FTA rate for the specialist paediatric staff dentists from 29.2% to 24.4% for 2006 and 2007 respectively. The cost of sending text messages was 28.15 pound (approx. 30 euro) for October 2007.


CONCLUSIONS
The use of SMS text messages as a reminder may reduce the failure to attend rate for outpatient paediatric dental appointments.
