Utilizing Consumer Health Informatics to Support Management of Hypertension by Clinical Pharmacists in Primary Care

Study Overview
=================
Brief Summary
-----------------
The purpose of this research study is to test the feasibility, acceptability, and preliminary effectiveness of the use of a mobile pharmacist-led intervention that incorporates home BP monitoring and medication reminders with patients recruited from a primary care setting, as well as identify challenges and potential solutions to broader implementation of a mobile pharmacist-led home-based BP monitoring intervention in primary care clinics through key stakeholder interviews.
