NCT05610059

Brief Summary

This randomized controlled trial will assess the efficacy and scalability of a blood pressure technology system intervention. The investigators will enroll 224 older adults with hypertension to identify those who are nonadherent for one hypertension medication. The participants will be randomized to one of two groups (112 per group) to use the blood pressure system for 6-months. Both groups receive information about high blood pressure and medications. One group will also receive strategies that can be used to take medications and manage blood pressure. Both groups will complete a mid-assessment at 3-months and a post-assessment at 6-months.

Outcome Measures

Primary Outcomes (2)

  • Medication Adherence (MEMS Cap)

    The Medication Event Monitoring System (MEMS®Cap) assesses objective medication adherence using the smart pill bottle cap. Digital sensors in the track cap automatically record the date and time of cap opening and upload the information to AARDEX Medication Adherence Software. Percentage of medication taken at the correct time frame.

    3 months, 6 months

  • Medication Adherence Report Scale (MARS-5)

    The Medication Adherence Report Scale (MARS-5) is a 5-item self-report scale to assess medication adherence related to the frequency of not taking a prescribed dose of medication or not taking the dose prescribed. Self-report score of 5-25. Item scores are summed for a total scale score, where higher scores reflect greater medication adherence. Scale: 5=never, 4=rarely, 3=sometimes, 2=often, and 1=always.

    3 months, 6 months
