Development and Evaluation of Patient Information Leaflet for Diabetic Foot Ulcer Patients

[Background]Patient education (PE) is as important as medical and surgical interventions in the management of diabetic foot ulcer (DFU). Patient information leaflets (PILs) are globally accepted patient counseling aids.[Objectives]This study aimed at developing PILs for DFU patients and investigating its validation.[Methods]The PILs were prepared based on different model leaflets available from various online resources, including “Patient UK”. The PILs readability was evaluated by Flesch/ Flesch-Kincaid readability (FRE/FK-GL) method before user-testing (n = 34 DFU patients) by quasi-experimental methods in patients with DFU. Additionally, user-opinion on legibility and content of the PIL was also determined. Baker Able Leaflet Design (BALD) method was employed to assess the layout and design characteristics of the PIL.[Results]The best FRE score achieved was 73.9 and the FK-GL score was 6.1. The mean BALD assessment score for English and Kannada versions of PIL were 27 and 26, respectively. The ICC of the test-retest reliability of user-testing and user-opinion questionnaires in both English and Kannada ranged from 0.91 to 0.96. The overall user-testing knowledge-based mean score significantly improved from 43.4 to 69.7 (P < 0.05). Overall, 82.4% of patients reported overall user-opinion on legibility and content of the PIL as good.[Conclusions]The developed PILs met the criteria of fairly easy readability and good layout design. The user-opinion of the majority of patients reported the PIL content, legibility, and design as good. The Pictogram-based PILs (P-PILs) was found to be an effective PE tool in DFU patients.
