BackgroundMany patient education materials (PEMs) available on the internet are written at high school or college reading levels, rendering them inaccessible to the average US resident, who reads at or below an 8(th) grade level. Currently, electronic health record (EHR) providers partner with companies that produce PEMs, allowing clinicians to access PEMs at the point of care.ObjectiveTo assess the readability of PEMs provided by a popular EHR vendor as well as the National Library of Medicine (NLM).DesignWe included PEMs from Micromedex, EBSCO, and MedlinePlus. Micromedex and EBSCO supply PEMs to Meditech, a popular EHR supplier in the US. MedlinePlus supplies the NLM. These PEM databases have high market penetration and accessibility.MeasurementsGrade reading level of the PEMs was calculated using three validated indices: Simple Measure of Gobbledygook (SMOG), Gunning Fog (GFI), and Flesch-Kincaid (FKI). The percentage of documents above target readability and average readability scores from each database were calculated.ResultsWe randomly sampled 100 disease-matched PEMs from three databases (n = 300 PEMs). Depending on the readability index used, 30-100% of PEMs were written above the 8(th) grade level. The average reading level for MedlinePlus, EBSCO, and Micromedex PEMs was 10.2 (1.9), 9.7 (1.3), and 8.6 (0.9), respectively (p ≤ 0.000) as estimated by the GFI. Estimates of readability using SMOG and FKI were similar.ConclusionsThe majority of PEMS available through the NLM and a popular EHR were written at reading levels considerably higher than that of the average US adult.
