To estimate the impact of infliximab (IFX) maintenance therapy on the use of hospital resources in patients with Crohn's disease (CD).


Medical records of patients treated with IFX maintenance therapy (5 mg/kg body weight; intravenous infusion) for luminal (L) or fistulizing (F) CD at 13 hospitals were retrospectively reviewed. Patients were assessed as their own controls. Use of CD-related healthcare resources was recorded comparing 1-year periods before and after first IFX infusion (pre-IFX and post-IFX).


One hundred fifty-three CD patients (n=84 L; 69 F) fulfilled the inclusion criteria. Mean number of IFX infusions was 7/y with an average of 335 mg/infusion dose/patient. During the pre-IFX period, 55% of patients needed hospitalization versus 31% in the post-IFX period (P<0.001). Mean inpatient stay was 11.3 d/y [11.2 (L), 11.5 (F)] for the pre-IFX period, and 6.3 d/y [6.2 (L), 6.3 (F)] in the post-IFX period (P<0.001). Surgery was required in 24% patients in the pre-IFX period and in 11% post-IFX (P<0.001). There were no significant changes in the incidence of outpatient visits although emergency room visits fell significantly.


Maintenance IFX in CD patients is associated with decreases in the use and length of hospitalizations and the need for surgery in clinical practice.
