Optimizing Sustainable Cuff Access and Training Pathways for Self-Measured Blood Pressure Monitoring in Primary Care

The study team developed a clinical integration package as a multicomponent primary care-based approach to increase SMBP adoption through structured workflows, patient training, blood pressure logs, reminders/support, and clinical follow-up. Pilot work demonstrated that SMBP uptake can be significantly improved in underserved primary care settings. However, the pilot relied on research funds to purchase cuffs, which is not sustainable for health-system scale. A scalable model must identify practical pathways for patients to obtain standard validated blood pressure cuffs through routine care mechanisms, including vendor-supported, insurance-billed, consignment, or mail-order pathways, without depending on research-purchased devices.

In addition to cuff access, effective SMBP implementation also requires feasible approaches to patient training. Many patients do not receive standardized instruction on how to correctly measure and record home blood pressure readings, and intensive in-person training models may be difficult to sustain in routine primary care workflows. Health systems therefore need practical training strategies that balance effectiveness with scalability, ranging from brief hands-on education delivered during clinic visits to lower-touch written or self-guided educational materials.

Patients will be randomized to one of four arms:

• Mail-order cuff delivery with hands-on training
• Mail-order cuff delivery with written instructions
• In-clinic cuff distribution with hands-on training
• In-clinic cuff distribution with written instructions

All other intervention components will be standardized across study arms, including receipt of a blood pressure log, written instructions on when and how to obtain home blood pressure readings, and routine clinic processes for documenting or reviewing SMBP readings returned by patients. The design is intended to evaluate implementation pathways for SMBP delivery in routine care rather than to test the clinical efficacy of SMBP itself. This design is intended to evaluate operational implementation pathways for SMBP delivery in routine care rather than to test the clinical efficacy of SMBP itself.
