Effect of Reminder Devices on Medication Adherence

A study of three low-cost reminder devices concluded there was no statistically significant increase in medication adherence among patients using them, compared with those receiving no reminders. The four-arm, block-randomized clinical trial involved more than 53,000 enrollees of CVS Caremark. Participants were aged 18–64 years and taking 1- 3 oral medications for long-term use. The patients were stratified on the basis of the medications they were using at randomization: medications for cardiovascular or other nondepression chronic conditions and antidepressants.
