Increasing the Use of Self Measured Home Blood Pressure Logs in the Management of Hypertension

Telephone-Based Patient Outreach to Improve Self-Measured Blood Pressure Log Utilization in Chronic Hypertension: A Pragmatic Quality Improvement Randomized Implementation Trial

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
No Intervention: Usual Care; The control arm represents usual care, wherein patients receive standard medical management for chronic hypertension without any additional telephone outreach or targeted education regarding blood pressure logging workflows.
Experimental: A structured, telephone-based educational outreach to encourage HBPM; The intervention arm consists of a structured, telephone-based educational outreach led by medical students using a standardized script to provide brief education on the clinical value of HBPM and to encourage patients to maintain and present a monitoring log at their subsequent clinic visit. This arm utilizes a maximum of two call attempts per patient with no voicemail messages left to determine if a simple, low-resource reminder can influence patient behavior.	Other: A structured, telephone-based educational outreach to encourage HBPM; Telephone-based educational outreach to encourage HBPM

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
HBPM Log Adherence	The primary outcome was the proportion of patients with a documented home blood pressure log in the electronic health record (EHR). A "documented log" was operationally defined as any notation in the medical record indicating that a patient presented with, reported, or submitted home blood pressure readings, whether through a scanned paper log, free-text documentation in a clinical note, or an entry in a structured data field	Adherence was measured at follow-up within a 90-day window of the intervention.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Blood Pressure	The secondary outcomes consisted of the mean change in both systolic and diastolic blood pressure. These clinical metrics were selected to evaluate the impact of the HBPM intervention on objective blood pressure control	The most recent follow-up measurement recorded within a 90-day window of the intervention.
