Abstract
Background

In the primary care setting, compliance with lipid lowering therapy was relatively low. In order to compare the efficacy of a short messaging service (SMS) text messaging and postal reminder as means of improving attendance rates during the first 24 weeks of lipid-lowering therapy, a randomized controlled trial of 918 patients from 19 family practice clinics was conducted between February 2003 and June 2006.


Methods

Patients were randomly assigned into 3 groups: SMS (327), postal (294),and control (297) group. To ascertain attendance rates, patients were followed up at 24 weeks after their treatment. Reminders were sent at 16 weeks from the coordinating center.


Results

Overall attendance rate was 74.1%. This differed between groups, with 76.1% attendance for the SMS group, 73.5% for the postal group, and 72.4% for the control group. According to a multivariate analysis, the SMS group had a significantly higher attendance rate (Odds ratios [OR] 1.48; 95% confidence interval [CI], 1.01 to 2.16) than the control group, but the postal group (OR, 1.15; 95% CI, 0.79 to 1.69) did not. Moreover, the cost per attendance for the SMS reminder (155 Korean Won [KRW]) was much lower than that for the postal reminder (722 KRW).


Conclusion

SMS reminder may be more cost saving method to improve the attendance rate compared with the postal reminder.
