ASPIRE: Adapting Self-Blood Pressure Monitoring to Reduce Health Disparities

Barriers to blood pressure control are multi-faceted and a silver-bullet solution/intervention does not exist. Therefore, the literature highlights the importance of creating multi-component interventions when addressing blood pressure control. The ASPIRE intervention consists of 5 components identified based on the study team's prior work and review of the literature.

Patients randomized to the intervention arm will receive all 5 components of the ASPIRE intervention. Patients randomized to the control arm will receive only the first component of the ASPIRE intervention and will continue to receive usual care. The ASPIRE intervention consists of 5 components aimed at supporting both patients and clinic care teams in successfully adopting self-measured blood pressure (SMBP) into their clinic workflow.

The 5 ASPIRE components are:

1. Access to cuff (Patient). Patients in the intervention arm and control arm will be measured for and will receive a blood pressure monitoring device to take home and keep beyond the study timeline.

2. Training (Patient). Only patients in the intervention arm will receive training and support on how to accurately measure their blood pressure. They will receive a folder containing an infographic that demonstrates how to accurately measure blood pressure at home. They will also receive a lifestyle infographic describing what they can do to improve their blood pressure.

3. Clear instructions (Patient). Patients in the intervention arm will also receive clear instructions on how to keep a record of their home blood pressure measures and share with their care team. They will be provided with a 7-day blood pressure long that details the number of blood pressure values they need to take in the mornings and evenings for seven days. Additionally, a clinic care team member serving as the ASPIRE coach will follow up with the intervention patients via a scheduled virtual call one week after they receive their materials (blood pressure monitoring device, infographics, and 7-day blood pressure log) to provide further support and instructions on self-measured blood pressure and to emphasize the importance of returning the blood pressure values to their care team.

4. SMBP EHR Documentation (ASPIRE Coach). To facilitate documentation of home blood pressure values in the electronic health record (EHR), the ASPIRE coach will average the blood pressure values patients return and document that average in the EHR. These home blood pressure averages will be shared with the patient's doctor who can use these values to modify treatment as appropriate.

5. Address Social Determinants of Health (Patient). Patients will be screened for social needs via a social determinants of health (SDOH) questionnaire that they will be asked to return to the care team. During the one week follow up virtual call the ASPIRE coach will address any identified social needs by following up with referrals as needed.
