Team-based home blood pressure monitoring for blood pressure equity a protocol for a stepped wedge cluster randomized trial.

Background: Home Blood Pressure Monitoring (HBPM) that includes a team with a clinical pharmacist is an evidence-based intervention that improves blood pressure (BP). Yet, strategies for promoting its adoption in primary care are lacking. We developed potentially feasible and sustainable implementation strategies to improve hypertension control and BP equity.

Methods: We assessed barriers and facilitators to HBPM and iteratively adapted implementation strategies through key informative interviews and guidance from a multistakeholder stakeholder team involving investigators, clinicians, and practice administration.

Results: Strategies include: 1) pro-active outreach to patients; 2) provision of BP devices; 3) deployment of automated bidirectional texting to support patients through education messages for patients to transmit their readings to the clinical team; 3) a hypertension visit note template; 4) monthly audit and feedback reports on progress to the team; and 5) training to the patients and teams. We will use a stepped wedge randomized trial to assess RE-AIM outcomes. These are defined as follows Reach: the proportion of eligible patients who agree to participate in the BP texting; Effectiveness: the proportion of eligible patients with their last BP reading <140/90 (six months); Adoption: the proportion of patients invited to the BP texting; Implementation: patients who text their BP reading ≥10 of days per month; and Maintenance: sustained BP control post-intervention (twelve months). We will also examine RE-AIM metrics stratified by race and ethnicity.

Conclusions: Findings will inform the impact of strategies for the adoption of team-based HPBM and the impact of the intervention on hypertension control and equity.
