Background:
We explore an innovative approach by transforming patient information leaflet (PILs) into Quick Response (QR) code linked patient information videos (PIVs) in ophthalmology. Our objectives are to assess the subjective utility of a PIV on glaucoma and analyse the use of QR codes as a delivery method.
Methods:
A prospective study was conducted in Ninewells Hospital, NHS Tayside. A glaucoma PIV was created and linked to a QR code provided to 130 glaucoma patients. Pre- and post-video questionnaires evaluated the patients' perception of using a QR code and subjective improvement in their understanding of glaucoma.
Results:
Out of 102 responses collected, 55% of patients had no prior experience with QR codes. However, 81% of patients were able to watch the PIV. The average view duration of the video was 3:26, with 82.5% view retention. Statistically significant improvement in glaucoma knowledge was observed across all six areas questioned (p < 0.001) using a 5-point Likert scale. Overall, 70% of patients preferred PIVs over PILs, and 77% acknowledged that PIVs could be a sustainable alternative.
Conclusion:
QR codes for delivering PIVs were well-received, with patients finding them easy to use. Our PIV on glaucoma effectively enhanced patients' understanding of the condition.
