Behavioral Economics and Medication Adherence for Hypertension
- Randomised controlled trial
- 3 safety-net clinics
Authors' conclusion
In a diverse safety-net population, the BETTER-BP intervention doubled the rate of adequate antihypertensive medication adherence but did not reduce SBP at 6 months.
Study context
- Population
- Adults with hypertension on ≥1 antihypertensive medication, systolic blood pressure (SBP) >140 mm Hg and poor self-reported adherence, New York City safety-net clinics
- Participants
- 400 adults
- Comparison
- mHealth incentive lottery vs control
- Interventionn = 265
- Controln = 135reference
- Primary endpoint
- Clinical: change in SBP; process: adequate antihypertensive medication adherence (≥80% days adherent)
- Follow-up
- 6 months
