Background
The Crohn’s and Colitis Knowledge (CCKNOW) score, which was developed more than 15 years ago, does not reflect updated knowledge relating to inflammatory bowel disease (IBD). The aim of this study was to develop, validate, and apply a novel tool (IBD-KNOW) to measure disease-related knowledge in patients with IBD.
Methods
A draft questionnaire consisted of 51 items regarding knowledge of various aspects of IBD (anatomy, function, epidemiology, diet/life style, general knowledge, medication, complication, surgery, reproduction, and vaccination) was constructed. After 2 pilot studies on 40 IBD patients and through the revision, a final questionnaire with 24 items was completed. Discriminate ability of this ‘IBD-KNOW’ was validated in 3 groups with different levels of IBD-related knowledge (14 gastroenterology fellows, 20 ward nurses, and 19 from the administrative staff). CCKNOW and IBD-KNOW were administrated to 193 IBD patients in 3 tertiary hospitals. Patient factors affecting the level of IBD-related knowledge were analysed.
Results
The median IBD-KNOW score was significantly different amongst the 3 groups for validation (22 gastroenterology fellows, 20 ward nurses, and 5 from the administrative staff, p < 0.001). IBD-KNOW showed excellent internal consistency (Cronbach alpha = 0.952) and high correlation with CCKNOW (Spearman’s ρ = 0.827, p = 0.01). In total, 193 IBD patients (Crohn’s disease 118 and ulcerative colitis 75) completed both questionnaires. The mean score of IBD-KNOW and CCKNOW was 13.3 and 9.4, respectively. Better IBD-KNOW score was associated with never or past smoker, disease duration more than 5 years, history of hospitalisation or operation, high education level (college/university or more), IBD-related information acquisition from Internet/books/patient organisation. Multivariate logistic regression analysis showed that the higher IBD-KNOW score than the median was associated with history of hospitalisation (RR 4.051, 95% CI 1.841–8.911, p = 0.001), high education level (RR 2.439, 95% CI 1.074–5.538, p = 0.033), and information acquisition from patient organisation (RR 3.645, 95% CI 1.172–11.340, p = 0.025).
Conclusion
IBD-KNOW, a novel assessment tool of IBD-related knowledge, has demonstrated excellent test characteristics. History of hospitalisation, education level, and information acquisition from patient organisation play important roles for acquisition of correct IBD-related knowledge.
