Adverse Events and Compliance Among Inflammatory Bowel Disease Patients Treated With Home- vs Office-Based Biologic Infusions.

Background: Biologic medications are a common therapy for those with inflammatory bowel disease (IBD). There are limited data on the outcomes of home-based biologic infusions for patients with IBD. The aim of this study was to compare the safety and efficacy of biologic infusions for IBD patients who receive either home- or office-based administration.
Methods: Patients receiving infliximab or vedolizumab were analyzed retrospectively over a period of 152 weeks. Survival free of major adverse events including delayed infusion reaction, steroid initiation, drug discontinuation, or IBD-related emergency department visits, admission, and surgery were compared using a Kaplan-Meier curve. Individual adverse events, infusion-.related quality measures, and markers of patient adherence were analyzed.
Results: Adverse event-free survival was greater among those receiving home-based infusion (n = 154) compared with office-based infusion (n = 133). The office infusion cohort had higher rates of delayed infusion reactions (4 vs 0), IBD-related surgery (6 vs 0), and drug discontinuation (44 vs 35); this was a sicker cohort of patients compared with those in the home infusion group. Home infusion patients were less likely to receive correct weight-based dosing for infliximab (71.7% vs 89.3%), obtain labs for drug monitoring (53.2% vs 71.4%), and adhere to routine clinic visits (37.9% vs 58.1%).
Conclusions: The home-based infusion of biologics for IBD appears safe with lower rates of major adverse events compared with office-based infusions. However, those receiving home infusion were less likely to receive correct weight-based dosing for infliximab and were poorly adherent to routine follow-up.
