High Blood Pressure
Conditions
Brief summary
BETTER-BP (Behavioral Economics Trial To Enhance Regulation of Blood Pressure) is a phase II, single-center, prospective, pragmatic randomized clinical trial within the New York City Health and Hospitals (NYC-H+H) system and NYU Langone Family Health Centers. The trial will recruit from 3 NYC-H+H ambulatory clinics as well as NYU Langone Family Health Centers, and will use a lottery incentive program to promote adherence to antihypertensive medication that will be delivered via smartphone for 6 months. The trial will randomize 435 patients with hypertension determined to have poor adherence (\<80% adherence with antihypertensive medication), in a 2:1 (intervention:control) ratio. Baseline enrollment will occur over 36 months with an expected 12 months follow-up per participant.
Interventions
3 in-person study visits, approximately one hour each. These will take place at baseline, 6 months, and 12 months.
Delivered by the Way to Health platform, installed on a smartphone and communicates with participants via text message.Participants are eligible to receive a potential cash reward if they are adherent with their antihypertensive medication the day before, which is monitored via electronic monitoring device (EMD) from AdhereTech. Each participant is assigned a 2-digit number for the trial, and each day the Way to Health platform randomly generates a 2-digit number. Participants will receive a prize if both digits match (1 in 100 chance) and will receive a prize of lesser value if one digit matches (18 in 100 chance). If they are not adherent with their medication, but would have won if they were adherent, they receive a text message that they would have won ("regret" component).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Systolic Blood Pressure (SBP) | Baseline, Month 6 | Three seated BPs will be measured after a rest period (5 minutes) using an automated device (Omron, Lake Forest, IL) which will reduce the potential for observer bias. The average of the three measurements will be recorded as the value for that time period. The change is the difference in mean measurements during each time period. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With Adequate Antihypertensive Adherence | Baseline, Month 6 | Measured with a wireless Tech wireless which transfers data via cell phone to the Way to Health platform. Adequate adherence defined as ≥ 80% of days adherent from baseline to 6 months. Adherence was calculated using the scheduling adherence metric, which is the proportion of days that a participant took their prescribed medication divided by the total number of days that they were expected to take medication in a given period. |
