Patient and Healthcare Professional Perspectives on Crohn's Perianal Fistula Treatment: Results From a Discrete Choice Experiment

Background: Crohn's perianal fistulas (CPF) are difficult to manage and often require multiple interventions. This study aimed to assess the preferences of patients and healthcare professionals (HCPs) for attributes of CPF-related procedures/surgeries to better inform CPF management.

Methods: This US cross-sectional, observational study was conducted via a web-enabled questionnaire (October 2021-January 2022) among patients aged 21-89 years with a self-reported physician diagnosis of CPF (with or without CPF-related surgery experience) and HCPs (gastroenterologists and colorectal surgeons who managed ≥3 patients with CPF in the past 12 months). Patient and HCP preferences for CPF-related procedure/surgery attributes were assessed using a discrete choice experiment and stated preference methodology.

Results: In total, 100 patients and 137 HCPs were recruited. Benefits of therapy (symptom control and/or fistula closure) were rated as the most important CPF treatment attribute by both patients and HCPs influencing treatment decisions (mean relative importance 23.9 and 36.3, respectively). The mean relative importance of procedure invasiveness and postoperative discomfort was higher for patients (19.3 and 20.2, respectively) than for HCPs (14.3 and 11.0, respectively), whereas the mean relative importance of fecal incontinence was greater for HCPs than patients (25.0 vs. 19.3, respectively).

Conclusions: Patients and HCPs have different perspectives on the importance of specific CPF-related procedure/surgery attributes. The attributes identified as important to patients and HCPs in this study should be considered when managing patients with CPF and making treatment decisions.
