The impact of medical terminology on readability of patient education materials.

Most health-related literature is written above the reading ability of the lay audience; however, no studies to date have identified the impact of medical terms on readability of health education materials. The purpose of this study was to identify whether there was a change in calculated reading levels of patient education brochures after medical terms were removed from analysis passages. The reading levels of 5 patient education brochures were analyzed before and after removal of medical terms, using both the Fry and Simple Measure of Gobbledegook (SMOG) readability formulas. Results indicated that the reading levels for all brochures were significantly lower after removal of medical terminology, but they remained above the 5th to 6h grade level recommended by health education experts. Findings hold implications for healthcare professionals in relation to the development and evaluation of patient education materials.
