Beyond Medication Adherence: The Role of Patients' Beliefs and Life Context in Blood Pressure Control

In: Ethnicity & disease: an international journal on population differences in health and disease patterns, Volume 29, Issue 4, p. 567-576

Abstract

Objectives: Despite numerous interven­tions to address adherence to antihyperten­sive medications, continued high rates of uncontrolled blood pressure (BP) suggest a need to better understand patient factors beyond adherence associated with BP con­trol. We examined how patients' BP-related beliefs, and aspects of life context affect BP control, beyond medication adherence.Methods: We conducted a cross-sectional telephone survey of primary care patients with hypertension between 2010 and 2011 (N=103; 93 had complete data on all variables and were included in the regression analyses). We assessed patient so­ciodemographics (including race/ethnicity), medication adherence, BP-related beliefs, aspects of life context, and used clinical BP assessments.Results: Regression models including sociodemographics, medication adherence, and either beliefs or context consistently predicted BP control. Adding context after beliefs added no predictive value while adding beliefs after context significantly predicted BP control.Conclusion: Including patients' BP beliefs after context had the strongest effects on BP control.Practice Implications: Results suggest that when clinicians must choose a dimen­sion on which to intervene, focusing on beliefs would be the most fruitful approach to effecting change in BP control.Ethn Dis. 2019;29(4):567-576; doi:10.18865/ ed.29.4.567
