Overview
Brief Summary
The study team is proposing a single arm intervention to test the effect of an electronic intervention on medication use among individuals with a prescription for hypertension/high blood pressure. The investigator proposes that technology like text messaging, email, web applications and mobile apps with proven, nurse intervention scripts, will lead to significant, cost-effective improvements in hypertension medication use.
Detailed Description
The intervention will incorporate a scalable electronic intervention using Email/Web Apps and Short Message Service (SMS)/Mobile Web Apps. The study team will examine the participants' responses to the electronic encounters in the technology-only intervention throughout the 3-month study timeframe.

Outcomes
Primary Outcomes
Proportion of Days Covered (PDC)
Time Frame: 3 months
Proportion of Days Covered (PDC), a Pharmacy Quality Alliance (PQA)-recommended metric for estimation of medication adherence for patients using chronic medications, will be used to identify the percentage of patients taking medications in a particular drug class with high adherence (PDC \> 80% for the individual). Participants with a PDC ≤0.8 will be categorized as having "poor" adherence, and those with a PDC \>0.8 will be categorized as having "good" adherence. For analyses, the PDC will be dichotomized at 0.8 (PDC \>0.8) over the entire 3 month follow-up, yielding a single assessment of pill refill adherence that will be used as the primary outcome.
