Purpose: This study examined the reading difficulty of Consumer Medicine Information leaflets of five chronic-disease medicines. Design/ Methodology/ Approach: In this descriptive, cross-sectional study, 192 leaflets were randomly downloaded from the World Wide Web: Asthma (35), Cancer (42), Diabetes (41), HIV (29), and Hypertension (45). Text from each ‘leaflet’ was analysed using the Simple Measure of Gobbledygook (SMOG), Flesch Reading Ease, and Gunning Fog indexes. Findings: Consistently, the difficulty of the texts exceeded the recommended difficulty levels. A comparison of mean scores showed leaflets for HIV medication were the most difficult to read because they were written at grade levels too high for the average literate adult. Research Limitations: Readability indexes are suited to only prose. They neither measure how well-organised the text is, nor indicate the suitability of typographical features, such as illustrations, typeface, appeal of presentation, and use of white space. Readability scores do not account for readers’ backgrounds, exposure, and motivation. Practical implication: Developing user-friendly consumer medicine information leaflets can reduce the need for extensive explanations, allowing healthcare providers to allocate their time more efficiently. Social Implication: Improving the readability of Consumer Medicine Information leaflets can enhance health literacy, leading to better health outcomes and reduced healthcare costs associated with medication errors. Originality/Value: While readability indices have been widely used, their application specifically to Consumer Medicine Information leaflets for chronic ailments such as diabetes, hypertension, asthma, arthritis, and heart disease in Ghana is novel. Chronic ailments require continuous and often complex medication regimens, making readability particularly crucial.
