ABSTRACT
BACKGROUND: Millions of Americans search the Internet for health-related information; however, the readability and comprehensiveness of consumer medication information (CMI) on the Internet has not been widely studied. OBJECTIVE: The purpose of this study was to evaluate the readability and comprehensiveness of online CMI. METHODS: The readability and comprehensiveness of consumer drug information found on 3 well-known Web sites (Medline Plus, Yahoo Health, and WebMD) was evaluated; in particular, information related to 10 commonly prescribed medications. Readability was assessed using the Simple Measure of Gobbledygook (SMOG) and Fry Readability Graph (FRG) tools; comprehensiveness of information was evaluated using the Keystone action plan criteria. RESULTS: Using SMOG, the mean reading level of each Web site was 13th grade level or higher. Using the FRG, the mean reading level was 10th grade or higher. Out of the 24 points in the Keystone action plan criteria, information found on each of the Web sites was deemed accurate with mean score of 21, 21, and 19 for Medline Plus, Yahoo Health, and WebMD, respectively. CONCLUSIONS: For the medications reviewed, CMI found on Web sites was accurate when assessed using the Keystone action plan criteria. The readability levels were higher than the recommended sixth grade level.
