Abstract
Background
People with reduced health literacy are at higher risk of not sufficiently understanding informed consent prior to procedures. Approximately 44% of adults read at or below the age of an average 12-13-year-old, indicating they may struggle to understand basic health information during the consent process. This is magnified in indigenous peoples, older adults and those with English as a second language in both countries.
Methods
We designed a procedural graphic comic booklet to be shared prior to the consent process, aiming to increase understanding in all patient groups. Pilot research on patients’ understanding of basic probability was conducted using non-medical questions confirmed poor understanding of risk. The comic booklet was developed with patient and health literacy group input and subjected to several cycles of feedback to reach the final version utilised in our audit.
Results
We audited patient and staff perceptions of the graphic comic booklet to the commonly used Heart Foundation information booklet. In 15 patients and 12 health-workers, the graphic comic booklet format was felt to be more succinct and understandable and was preferred by the majority of respondents. A small group preferred more detailed information.
Discussion
The use of a graphic comic booklet can therefore be an important educational tool, aiding patient understanding of procedures prior to the consent process. We intend to use it in addition to the current pre-angiography education provided to patients.
