NCT ID NCT06543394
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how to best reach adults with uncontrolled high blood pressure who struggle to take their medications as prescribed. Researchers will test different recruitment letters and phone call strategies to see which approach gets more people to attend a counseling session with a pharmacist. The goal is to find the most effective and practical way to help patients manage their blood pressure long-term.
