Promoting Medication Adherence Among Older Adults With Hypertension
15 ottobre 2020 aggiornato da: Marie Krousel-Wood, Tulane University School of Medicine
Overcoming Immunity to Change: A Feasibility Study of a New Method to Promote Medication Adherence Among Older Adults With Hypertension
Over 70% of US adults 65 or older are diagnosed with hypertension, the leading cause of cardiovascular disease and premature deaths in the world. Despite availability of effective drugs to control blood pressure, uncontrolled blood pressure and low adherence to antihypertensive drugs persist as major public health and clinical challenges. On average, 50% of adults adhere to chronic disease medications and lower levels of adherence are associated with worse blood pressure control and adverse outcomes. Many barriers to adherence are well known and have been targeted in interventions to improve medication adherence. As of yet, no single intervention has emerged as superior or even particularly effective in improving adherence. The investigators have recently identified unconscious, self-protective 'hidden motives' that contribute to nonadherence to chronic disease medications. There is a critical need to expand on this insight to test the potential for targeting individuals' 'hidden motives' for low adherence using an innovative learning process called Immunity-to-Change.
As a critical step in testing this intervention to target these 'hidden motives', the investigators will undertake a pilot study to assess the feasibility and acceptability of the Overcoming Immunity-to-Change intervention and determine effect sizes of the intervention on adherence, blood pressure (BP) control, and quality of life (QOL). The investigators will test the Immunity-to-Change intervention in a sample of nonadherent older adults with hypertension (n=18). Another sample of nonadherent older adults with hypertension will be monitored for comparison (n=18).

Sperimentale: Health coaching
Two-hour in-person group counseling session led by health coach, involving development of personalized immunity maps that lay out adherence goal, behaviors that distract from goal, hidden motives that compete with achieving goal, and underlying assumptions Eight 50-minute individual telephone counseling sessions every three weeks with a health coach, focusing on uncovering hidden motives and challenging assumptions with the goal of overturning nonadherence mindsets |
