Delays in Initiating Post-operative Prophylactic Biologic Therapy Are Common Among Crohn's Disease Patients.

BACKGROUND: Studies have shown that prophylactic biologic therapy can reduce post-surgical Crohn's disease recurrence.

AIMS: We aimed to identify the frequency of delay and risk factors associated with a delay in the initiation of prophylactic post-surgical biologic therapy in high-risk patients.

METHODS: We performed a cohort study of Crohn's disease patients who underwent a bowel resection. We identified those at risk of recurrence and explored multiple characteristics for those with and without a delay post-operatively.

RESULTS: A total of 84 patients were included in our analysis of which 69.0% had a greater than 4-week delay and 56.0% a greater than 8-week delay in post-surgical biologic prophylaxis. Publicly insured patients had a 100% delay in post-surgical prophylaxis initiation (p = 0.039, p = 0.003 at 4 and 8 weeks, respectively). Patients on a biologic pre-surgery were less likely to have a delay (p < 0.001) in post-operative prophylaxis. Care at an inflammatory bowel disease (IBD) center was associated with timely therapy when considering a post-operative immunomodulator or biologic strategy.

CONCLUSIONS: There are a substantial number of delays in initiating post-operative prophylactic biologic therapy in high-risk patients. Identifying susceptible patients by insurance type or absence of pre-operative therapy can focus future improvement efforts. Additionally, consultation with IBD-specialized providers should be considered in peri-surgical IBD care.
