Brief Summary

"Blood Pressure: Improving Control among Alaska Native People" (BP-ICAN) that targets blood pressure control among Alaska Native and American Indian (AN/AI) people diagnosed with hypertension. Participants will include adults with a diagnosis of hypertension who have not achieved blood pressure control. Primary Care Center (PCC) provider teams and associated panels of Alaska Native or American Indian (ANAI) adults will be randomized into the control or intervention arm. The investigators will recruit up to 10 ANAI adults per PCC provider for a total of 324 participants. Intervention participants will receive a home blood pressure monitor (HBPM), upload personal home blood pressure values into a data mall, and be encouraged to communicate with providers and pharmacists about HBPM results using an online electronic health record application, telephone, or other existing clinical processes. HBPM measurements for each intervention arm participant will be provided to provider teams and integrated pharmacists. Control participants will receive care as usual. Data will be collected over a 12 month period. Participants will meet with investigators at time of consent (baseline), and 3, 6, and 12 months after baseline. At each visit, participants will have blood pressure measured using 3 methods (aneroid sphygmomanometer, automated Omron upper arm cuff device, and automated Omron wrist cuff device), complete surveys, and have height, weight, and arm circumference measured. In-person measures are omitted during the pandemic and only one method of blood pressure measurement is used (upper arm cuff device). Clinical and service utilization information will be electronically queried with participant consent. The investigators will examine whether participants in the intervention arm have better blood pressure control at the end of the 12 month period than participants in the control arm.

Outcome Measures

Primary Outcomes (3)

  • Individual-level: within-person change in systolic blood pressure

    Examine change in systolic blood pressure (mmHg) between participants in the intervention group compared to the control group.

    12 months

  • Provider-level: frequency of antihypertensive medication adjustments

    Examine number of medication adjustments (new prescription or change in dose of antihypertensive medications) between participants in the intervention group compared to the control group.

    3 months, 6 months, and 12 months

  • System-level: change in systolic blood pressure for all patients with hypertension

    Examine change in systolic blood pressure (mmHg) between all patients whose providers are in the intervention group (receiving automated alerts about high blood pressure and pharmacist support), compared to patients whose providers are in the control group (do not receive alerts and pharmacist support).

    12 months

Study Arms (2)

BP-ICAN

ACTIVE COMPARATOR

Participants in the BP-ICAN arm will receive a home blood pressure monitor to be used twice daily for 12 months. Participants' home blood pressure measurements will be shared with their provider and participants will receive a series of text messages including topics on the importance of managing hypertension, reminders to measure blood pressure with their device, and motivational messages on diet and exercise.

Device: BP-ICAN

Control

NO INTERVENTION

Participants in the control arm will receive care as usual for the treatment of hypertension

Interventions

BP-ICANDEVICE

One of two home blood pressure monitor devices will be used. 1. Omron 7 Series Wrist cuff 2. Omron 10 Series Upper Arm cuff

BP-ICAN
