Health Literacy and Medication Adherence Among Patients Treated in a Free Health Clinic: A Pilot Study

Abstract

Background: A patient’s health literacy is not routinely assessed during visits with a health care provider. Since low health literacy is a risk factor for poor health outcomes, assessing health literacy should be considered as part of the standard medical workup. Objectives: To evaluate the health literacy levels and medication adherence of patients treated by pharmacists in both the general medicine and the chronic care clinics at an urban free health clinic. Methods: Eligible patients from the free health clinic completed the Rapid Estimate of Adult Literacy in Medicine (REALM), a health literacy measurement tool, during their clinic visit in 2011. Medication adherence was self-reported by the patients. Results: A total of 100 patients participated (mean age = 48). The majority of participants were female (56%) and white (55%). Most (64%) of the patients scored at a high school reading level according to REALM. Only 21% of participants read at a seventh- to eighth-grade level. Overall medication adherence rate was 73%. Forgetting to take medication was the most popular reason given for nonadherence. Conclusion: Disease state and adherence were significantly related in patients with HIV/AIDS and hypertension. Patient’s ethnicity was significantly associated with literacy levels (P
