OBJECTIVES: To assess infliximab infusion patterns in ulcerative colitis (UC) and assess the impact of persistence with infliximab maintenance therapy on UC-related hospitalizations, lengths of stay, and inpatient costs. STUDY DESIGN: Retrospective analysis of medical claims for UC patients newly initiating infliximab treatment. METHODS: Patients were aged >18 years and had 2 UC diagnosis codes, an infliximab index date between September 1, 2005, and January 31, 2008, and continuous enrollment for >12 months before and >14 months after the index date. Infliximab induction (first 56 days postindex) and maintenance (>56 days and <12 months postinduction) patterns were evaluated. Of patients with maintenance treatment, persistence was defined as a medication possession ratio (MPR) of >80%, and this group was compared with those without persistence (<80% MPR). RESULTS: Overall, 420 patients were included in the analysis; 84.3% (n = 354) continued to maintenance therapy. Maintenance infusion patterns were consistent with recommended prescribing information. A smaller proportion of patients with maintenance therapy persistence required hospitalization compared with patients without persistence (3.0% vs 20.4%; P <.001). Hospitalized patients with maintenance therapy persistence had significantly lower mean inpatient costs ($14,243 vs $32,745; P = .046), with a trend toward shorter mean lengths of stay (6.67 vs 9.71 days; P = .147) than patients without persistence. CONCLUSIONS: Infliximab maintenance therapy persistence in UC was associated with significantly fewer hospitalizations. Once hospitalized, patients with therapeutic persistence had significantly decreased inpatient costs.
