From recent research it’s concluded that sending an automated short message service (SMS) message 24 hours before the appointment to patient’s cell phones reduces nonattendance rates.
Another effective strategy to reduce nonattendance rates next to phone calls or letters as appointment reminders. But these require more time and money compared to automatic sent SMS messages. Other strategies mentioned in the literature are education about the importance of attending all appointments, faciltating appointment rescheduling.
How did they do it, this automated sms service (tech)?
A private company, Katu Company, and the Department of Health Informatics at Federal University of São Paulo established a partnership to implement and maintain two electronic medical record systems, Clinic Manager® and its related Web version, Clinic Web®. A compatible module was developed for sending reminders as SMS text messages to patients’ cell phones, with cost about US$ 10,000. It has been operating since June 2007. This module is based on open, low-cost technologies including webservices (SOAP/XML) and SQL-based data access.
This study was done in 5 clinics in Brazil, providing general practice. Patients could refuse the SMS service. Patients were not randomized. The researchers compared the total number of scheduled appointments at the clinics during the period studied and the appointments were grouped into appointments attended and not attended by the patients. Appointments attended by the patients were subgrouped into those with an SMS reminder sent and those with no reminder sent. Similarly, nonattended appointments were also subgrouped into those with an SMS reminder sent and those with no reminder sent. So this was not a randomized trial comparing two groups, one with sms reminders and one group without.
From the 5 clinics one was discarded from analysis due to protocol violation and one from the remaining four did not show the beneficial effects of the SMS service. Overall the mean rate of nonattendance when no appointment reminder was sent was 25.57%, and it was 19.42% when a reminder was sent. In cost-benefit in terms of money is also beneficial for the SMS service.
- Appointment attendance is also influenced by specialty
- SMS reminders to patients has ethical implications such as confidentiality and limitations such as switching telephone numbers, lack of cell phone
Anyone experience with this or other measures to lower nonattendance to clinic? Please let me know?
