BackgroundDespite the availability of evidence-based inflammatory bowel disease (IBD) guidelines, suboptimal care persists. There is little published research assessing barriers to IBD guideline adherence.AimTo identify barriers to IBD guideline adherence including gastroenterologists' knowledge and attitudes towards guidelines.MethodsAn online cross-sectional survey of 824 Australian gastroenterologists was conducted from April to August 2018, with 198 (24%) responses. A novel survey was developed that was informed by the theoretical domain's framework.ResultsConfidence in guideline recommendations was high; however, referral to them was low. The European Crohn's and Colitis Organisation guidelines were referred to most commonly (43.6%). In multivariate analysis, significant predictors of frequent versus infrequent guideline referral were: high confidence in the guideline (odds ratio (OR) 7.70; 95% confidence interval (CI): 2.43-24.39; P = 0.001), and low (≤10 years) clinical experience (OR 3.62; 95% CI: 1.11-11.79; P = 0.03). The most common barriers to guideline adherence were not having time (62%), followed by guideline specifics being difficult to remember (61%). Low confidence was reported in managing pregnancy and IBD (34%) and loss of response to therapy (29%). High confidence was reported in managing immunomodulators; however, only 43% answered the associated knowledge question correctly.ConclusionAlthough gastroenterologists have high confidence in guidelines, they use them infrequently, primarily due to specifics being difficult to remember and lack of time. Self-reported confidence in an area of IBD management does not always reflect knowledge. An intervention targeting these barriers, for example, computer-based clinical decision support tools, might improve adherence and standardise care.© 2021 Royal Australasian College of Physicians.
