Primary outcomePrimary: Difference in Change in Systolic Blood Pressure- 12 Months — -23.8; -19.6 mmHg
Summary
Bidirectional texting is an effective way to collect home blood pressure (BP) measurements from subjects, but collecting BP measurements and sending them to physicians does not necessarily lead to decreased BP. Pharmacist interventions have been successful in decreasing subject BP. However, pharmacists are expensive, and in successful interventions, spent a substantial amount of time collecting home BP measurements. In this study, a proven pharmacist intervention will be added to a bidirectional texting program to determine if a combined pharmacist-bidirectional texting intervention is successful at decreasing subject BP and increasing subject BP treatment intensification in a cost-effective manner. This study will be a cluster-randomized, controlled trial of a new intervention.
