The Telephone-Based Patient Outreach to Improve Home Blood Pressure Monitoring (HBPM) in Chronic Hypertension study is a pragmatic, randomized, open-label quality improvement implementation trial designed to evaluate the effectiveness of a structured telephone outreach intervention in increasing the proportion of patients with chronic hypertension who present to clinic visits with a completed home blood pressure log compared to the receipt of usual primary care services over a 90-day period. The study aims to address the inconsistent integration of HBPM-an evidence-based strategy endorsed by major guidelines to improve diagnostic accuracy and longitudinal management-into routine primary care workflows where no standardized educational or documentation process currently exists. Patients with documented chronic uncontrolled hypertension, defined as three documented readings exceeding 130/80 mmHg, are eligible for participation. Typically, patients at this academic primary care practice lack a standardized process for receiving education on home monitoring or a dedicated mechanism for documenting logs, which can lead to therapeutic inertia and missed opportunities to optimize treatment. The intervention is designed around a structured telephone outreach program led by medical students using a standardized script to provide direct patient education on the clinical value of HBPM and to encourage the completion and presentation of BP logs during subsequent primary care visits.

Inclusion Criteria:

• Patients must have a documented diagnosis of chronic uncontrolled hypertension
• "Uncontrolled" was defined as having three documented blood pressure readings exceeding 130/80 mmHg within the electronic health record.

Exclusion Criteria:

• None
