Summary

This will be a two--arm Randomized controlled trial (RCT) design that will assess efficacy of the Smartphone Medication Adherence Stops Hypertension (SMASH) mobile health ( mHealth) program compared to an enhanced standard care (SC) program. Participants will be African-American (AA) hypertension patients with no other known chronic diseases.

Participants found to have uncontrolled hypertension (HTN) and medication non-adherence via electronic device monitoring will be randomized to SMASH or enhanced Standard Care (SC). The SMASH group will receive reminders in the form of auditory and visual reminders from a pill monitoring device when their medication dose is due, they will monitor their blood pressure at home and will receive tailored motivational text messages based upon levels of adherence . Enhanced SC group will use the pill monitoring device without reminder functions enabled and will receive text messages on topics of healthy lifestyles not related to medication adherence and hypertension.

The active intervention will continue for 6 months and follow-up will continue for 1 year.
