Health literacy plays a vital role in patients' understanding of their prescribed medication instructions. To inform strategies to assist providers in communicating in a manner that is easily understood by patients, it would be beneficial to determine the relationship between health literacy and the day-to-day aspects of medication adherence. This study identified: 1) differences of health literacy levels in medication adherence; 2) the association between health literacy and medication adherence; and 3) and factors associated with medication adherence score. A convenience sample of older predominantly African-American patients (N = 389), over the age of 60, completed a cross-sectional survey. Chi-square analysis assessed health literacy differences in five aspects of medication adherence. Ordinary linear regression analysis determined factors associated with medication adherence score. Patients with limited health literacy were more likely to forget to take their medications and more likely to take less medication than instructed than patients with adequate health literacy (χ(5) = 15.91, p = .007, χ(5) = 10.31, p = .036, respectively). REALM score was also significantly associated with medication adherence score (β= .016, p < .001, β = .009, p = .033), respectively). Findings suggest that providers seeking to improve medication adherence in older adults, particularly African-American patients, should focus communication on assessing health literacy levels prior to discussing medication instructions.

OBJECTIVE - Diabetes patients with limited resources often experience suboptimal care. Less is known about the role of effective health communication (HC) in caring for low income diabetes patients.
METHODS - Ten health department clinics in TN participated in a trial evaluating a literacy-sensitive communication intervention. We assessed the quality of baseline HC and measured associations with diabetes outcomes. Assessments included: demographics, measures of HC, health literacy, self-care behaviors, self-efficacy, medication non-adherence, treatment satisfaction, and A1C. Unadjusted and adjusted multivariable regression models were used to test associations.
RESULTS - Participants (N=411) were 49.7±9.5 years, 61% female, uninsured (96%), with A1C 9.6±2.1. In unadjusted analyses, better communication, was associated with lower medication non-adherence (OR 0.40-0.68, all p<0.05), higher treatment satisfaction (OR 1.76-1.96, all p<0.01), portion size reduction (OR 1.43, p<0.05), diabetes self-efficacy (OR 1.41, p<0.05), and lower A1C (β=-0.06, p<0.01). In adjusted analyses, communication quality remained associated with lower medication non-adherence (AOR 0.39-0.68, all p<0.05), and higher treatment satisfaction (AOR 1.90-2.21, all p<0.001).
CONCLUSIONS - Better communication between low-income patients and providers was independently associated with lower medication non-adherence and higher treatment satisfaction.
PRACTICE IMPLICATIONS - Communication quality may be an important modifiable approach to improving diabetes care for vulnerable populations.
