Resource use in patients with Crohn's disease treated with infliximab.

AIM

To estimate the impact of infliximab (IFX) on hospital resources for patients with Crohn's disease.

METHODS

Resource use data for at least 1 year before (B-IFX) and after (A-IFX) infliximab administration were retrospectively collected for all patients treated with IFX at the Hospital Cabueñes (Spain). Direct costs calculated were: hospital-stays, surgeries, out-patient visits, diagnostic and laboratory tests, pharmacological treatments, and day-care hospitalization for IFX administration.

RESULTS

Patients (n = 34; mean age at treatment: 43.6 years) with 9.8 and 4.3 years (B-IFX and A-IFX, respectively) had their costs estimated. Partial or complete response was achieved in 82% of patients. Total annual B-IFX costs per patient were Euro 4,464, of which 62.4% was for hospitalization, 3.1% for surgery, 8.7% for consultation visits, 16.2% for diagnostic and laboratory tests, and 9.6% for other treatments. Total annual A-IFX costs per patient were Euro 10,594; of which 6.4% was for hospitalization, 0.8% for surgery, 4.2% for consultation visits, 7.6% for diagnostic and laboratory tests, 5.5% for other treatments, and 75.5% for IFX and its administration. The primary cost item was hospitalization (Euro 2,783) during the B-IFX period as opposed to IFX itself (Euro 7,996) during the subsequent A-IFX period.

CONCLUSIONS

In routine practice, IFX appears to be an effective treatment by reducing hospital-stays, but increases overall budgetary cost for patients with Crohn's disease.
