Readability of Patient Information on Hypertension in Korea

ABSTRACT

BACKGINFORMAROUND Patient education is an important component of family practice. Pamphlets and the websites have been one of the most common resources for patient education. Patient information has been assessed using criteria with marks allocated for its content, design, readability. Up to present there have been studies on content, design but not readability. The WHO identifies readability as an essential tool for people to increase control over their health. Therefore, patient information should be assessed readability. The objective of our study was to assess patient information leaflets and the websites on hypertension to determine the readability of information currently available to patients. METHODS: Ten leaflets were reviewed, five form the internet and five from other sources. A total of ten subjects were assessed for readability using 'grading system of vocabulary' presented by the Academy of Korea Education in 2002. RESULTS: In five leaflets, about 41.3% vocabularies were comprised of 1st and 2nd grade. The portion of vocabularies in higher grade than 4th was 35%. In the five websites, 41.3% vocabularies in 1st and 2nd grade were used. The mean reading level (calculated with weight) was 2.057 for the five leaflets and 2.050 for the five websites. These results indicated that the leaflets were easier to read than websites. But, both of them were not comprehensible to the majority of patients. CONCLUSION: All 10 patient information materials for hypertension were at higher readability level than high school level. As recommended levels of readability were lower than 2nd grade, educational materials need to be modified to meet the information needs for the people with low reading skills.
