Social Norms, Messengers, & Processing Fluency to Increase Hypertension

Status Completed

Clinical Trial Summary

Medicare Advantage beneficiaries ages 65-79 and insured by Humana with at least two unique fills of hypertension medication within the 2023 calendar year and adherence level between 60 and 85% will be identified using Humana Medicare Advantage claims data. Individuals meeting these inclusion criteria will be included and, with an institutional review board approved waiver of informed consent, will be randomized to one of 6 mailed messages or control (no message). The messages will be sent by Humana and use different behavioral techniques (social norms, messenger effects, and/or processing fluency) providing their medication refill score. Humana will send a second message within 60 days of the first message noting any changes in the refill score. The primary outcome will be the average end-of-year adherence in each arm. A secondary outcome will be the proportion of study participants with end-of-year adherence greater than or equal to 80%. The study team's hypothesis is that messages using dynamic social norms, messenger effects, and processing fluency in combination will more effectively increase average end-of-year adherence level compared to usual care. Humana will conduct all study participant outreach and data analyses, which will be performed using routinely collected insurance claims data. Regulatory oversight is conducted using Humana's centralized institutional review board (IRB) of record. The work completed by Humana study staff is funded by Humana, Inc. Dr. Choudhry and his colleagues (including subaward recipients ideas42 and Tuck School of Business at Dartmouth) will provide technical and subject matter expertise related to study research design and implementation, protocol design, statistical analysis, publication (abstract, poster, manuscript) preparation and/or review, and assistance throughout the peer review process including revisions and additional analyses if necessary for this project. The work completed by study staff at Brigham and Women's Hospital, ideas42, and Tuck School of Business at Dartmouth is funded by NIA.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
