Patient information leaflets (PILs) and educational videos help diabetic foot ulcer (DFU) patients with their foot care practices, selection of footwear, and prevention of further complications. The current study aims to compare the communicative efficiency of written PIL with audio-visual aids. PILs and educational videos were developed with inputs from peer-reviewed articles and international guidelines and validated by experts in healthcare, based on the content validity index. A pre- and post-quasi-experimental study without a control group was conducted. PIL readability was assessed by Flesch reading ease (FRE) and Flesch-Kincaid grade level (FKGL) tools. The design and layout of the PIL were evaluated using the Baker able leaflet design (BALD). The user opinions on the design and content of the PILs and educational videos were obtained with the help of questionnaires. The FRE and FKGL scores of the PIL were 81.4 and 6.1, respectively. The BALD scores of the English, Kannada, and Malayalam language PILs were 27, 28, and 26, respectively. The overall user-testing knowledge mean score of the PILs and videos significantly improved from 45.5 ± 11.26 to 69.33 ± 9.18 (p < 0.001) and 46 ± 15.20 to 84.33 ± 9.08 (p < 0.001), respectively. The overall user opinion was good for both the PIL [n = 54 (90%)] and video [n = 55 (91.67%)]. The study’s results showed a notable improvement in the degree of knowledge among the DFU patients after reading the PIL and watching the video. The education tool video had a higher impact on knowledge levels than PIL.
