Improving patient comprehension and recall of discharge instructions by supplementing free texts with pictographs.

Abstract

Inpatient discharge instructions provide critical information for patients to manage their own care. These instructions are typically free-text and not easy for patients to understand and remember. In this pilot study, we developed a set of pictographs through a participatory design process and used them to enhance two mock-up discharge instructions. Tested on 13 healthy volunteers, the pictograph enhancement resulted in statistically significant better recall rates (p<0.001). This suggests that patient comprehension and recall of discharge instructions could be improved by supplementing free texts with pictographs.
