Understanding the role of the primary care physician in the management of patients with Crohn's perianal fistulas.

Objectives: To understand the role of primary care physicians (PCPs) in the recognition, diagnosis, and management of Crohn's perianal fistulas (CPF) and their referral patterns and treatment expectations.

Methods: This survey-based study was conducted between September 2020 and October 2020. US-based PCPs managing at least one patient with Crohn's disease per week were included. Participants were presented with two case vignettes relevant to primary care practice; Case Vignette 1 comprised three parts and focused on initial CPF presentation and progression to partial response; Case Vignette 2 focused on recurrent CPF. Survey questions elicited the physician's clinical approach to each case. Data were presented as descriptive statistics.

Results: Overall, 151 PCPs (median 23 years in practice) who saw about three patients per month with new/existing CPF responded. For Case Vignette 1, upon identification of a fistulous tract, 89% of respondents would refer the patient, mostly to a colorectal surgeon or gastroenterologist. Most PCPs (69%) would begin the patient on medication; 46% would conduct a diagnostic/imaging study. Treatment expectations after referral varied: 55% of respondents believed surgeons would place a seton or use one prior to surgery; 23% expected medical management only; 23% were unsure. Case Vignette 2 revealed that 98% of PCPs preferred to be involved in patient care after referral; however, only 49% were. Of these, 76% considered reinforcing patient treatment adherence as their primary role. While 80% of PCPs were at least moderately satisfied with communication and care coordination with multidisciplinary teams, 52% considered lack of access to specialists as at least a moderate barrier to multidisciplinary team management.

Conclusion: PCPs want more involvement in multidisciplinary management of patients with CPF. Continuing education providing PCPs with up-to-date information on diagnostic modalities, treatment options, early diagnosis, the role of PCPs within a multidisciplinary team, and effective initial CPF care is required.
