Learning Objective #1: Identify the potential health impact low health literacy has on a patient's ability to interpret prescription instructions
Learning Objective #2: Understand the importance of assessing health literacy in the clinical setting

Background. Having adequate health literacy means that one obtains,interprets,comprehends and acts on health advice to promote wellness. Low health literacy is associated with a variety of negative clinical outcomes (1-4). African Americans (AAs) with asthma experience a disproportionate disease burden compared with Caucasians (5).

Methods. One hundred twelve adults with asthma (29% White, 66% AA; 82% female; 63% with < high school education, 45% Medicaid recipients, mean age 47 + 13.6 [range 17-80]) were administered the Rapid Estimate of Adult Literacy in Medicine (REALM) and asked to read and interpret a prescription (Rx) for an inhaled corticosteroid (ICS) and rescue inhaler.

Results. The mean REALM score was 56.3 + 13.6 (range 1-66) with 43% of the sample falling at or below the 8th grade reading level (low literacy; REALM score < 60). Twenty (18%) of the subjects were either unable to read the prescriptions or made errors in interpreting the prescriptions. Thirty-five percent of the low literacy group had difficulty reading or interpreting Rx compared to 5% of the literate group (p=.000). AAs were more likely to have low REALM scores (p=.001)and to make errors in reading or interpreting inhaler RX (p=.04) than Caucasians although this may be a function of AAs lower educational attainment compared to Caucasians (p=.000).

Conclusions: AA adults with asthma had lower health literacy than Caucasians; the inability to read or follow Rx directions may lead to inadequate self-management thereby contributing to the greater health disparities seen in AAs with asthma.
