Aminosalicylates are the most commonly prescribed therapy in Crohn's disease (CD), despite uncertainty in the evidence to support their efficacy.


To examine physicians' perspectives on aminosalicylate use for CD and explore the discordance between clinical practice and the evidence base.


A qualitative interview study was performed amongst physicians with at least 4 years of independent experience in managing CD patients. Semi-structured telephone interviews were conducted using an exploratory interview guide. Interview transcripts were thematically analyzed to elucidate concepts pertaining to treatment strategies for CD, motivations for prescribing aminosalicylates, perceived benefits and harms of aminosalicylate use, and the relationship between the evidence and real-world prescribing practices.


A representative sample of thirty physicians from four different countries and multiple practice environments (university/teaching hospitals, public practice, private/community practice, and subspecialty gastroenterology clinics) participated. Nearly all physicians (93.3%, 28/30) reported prescribing aminosalicylates for CD. Aminosalicylates were endorsed as first-line therapy for mild CD by nearly half of participants (13/30, 43.3%). A favorable safety profile, possible efficacy in mild colonic CD, and patient reluctance to step-up to other therapies were primary motivators for aminosalicylate use. Almost half of respondents (46.7%) expressed that the evidence informing aminosalicylate efficacy in CD differed substantially from their own clinical experience.


Physicians' beliefs about efficacy in subgroups of CD patients, safety, and patient preferences primarily motivate aminosalicylate prescription in CD. There is a lack of confidence in published clinical trials, and a desire for more robust evidence to inform 5-ASA use in CD.
