Assessment of patient education materials for age-related macular degeneration

Purpose

Age‐related macular degeneration (AMD) is a leading cause of vision loss. It is helpful for patients living with AMD to understand the prognosis, risk factors and management of their condition. Online education materials are a popular and promising channel for conveying this knowledge to patients with AMD. However, the quality of these materials—particularly with respect to qualities such as ‘understandability’ and ‘actionability’—is not yet known. This study assessed a collection of online materials about AMD based on these qualities of ‘understandability’ and ‘actionability’.

Methods

Online education materials about AMD were sourced through Google from six English‐speaking nations: Australia, New Zealand, USA, UK, Ireland and Canada. Three Australian/New Zealand trained and registered optometrists participated in the grading of the ‘understandability’ and ‘actionability’ of online education materials using the Patient Education Materials Assessment Tool (PEMAT).

Results

This study analysed a total of 75 online materials. The mean ‘understandability’ score was 74% (range: 38%–94%). The ‘understandability’ PEMAT criterion U11 (calling for a summary of the key points) scored most poorly across all materials. The mean ‘actionability’ score was 49% (range: 0%–83%). The ‘actionability’ PEMAT criterion A26 (using ‘visual aids’ to make instructions easier to act on) scored most poorly across all materials.

Conclusion

Most education materials about AMD are easy to understand, but difficult to act on, because of a lack of meaningful visual aids. We propose future enhancements to AMD education materials—including the use of summaries, visual aids and a habit tracker—to help patients with AMD improve their understanding of disease prognosis, risk factors and eye assessment schedule requirements.
