Background: Studies examining the treatment reality of IBD patients in Germany have been limited, as networking among deliverers of care and reliable documentation of medical, demographic, and economic data are lacking. The aim of the present study was to establish an internet-based treatment registry in order to evaluate treatment of IBD patients in Germany.
Methods: Between November 1(st), 2005, and January 31, 2007, 1024 outpatients with prevalent IBD from 10 gastroenterological private practices and 3 hospitals (UC = 439, CD = 567, ID = 18) were enrolled in the study. An internet-based registry was established that included data about medical history, disease status, diagnostic procedures, laboratory test results, and medical treatment. Data for private practices and hospitals were pooled in order to compare treatment habits between these types of medical facilities. The cost of medication was determined according to medications prescribed.
Results: There was no significant difference between the 2 patient groups in demographic and clinical characteristics. Marked differences were observed in medical treatment. The most frequently prescribed medications in the private practices for patients in remission and those with active disease were aminosalicylates and corticosteroids. Immunomodulators played a marginal role. In contrast, in the hospitals azathioprine/6-MP was predominantly used for the maintenance of remission. Patients with fistulizing CD were treated with infliximab. The mean annual cost of medications was 1826 +/- 1331euro/patient (median 1353euro) in the private practices and 1849euro +/- 2897euro/patient (median 960euro) at the University Hospital.
Conclusions: The registry provides the first detailed data about the reality of treatment of IBD patients in Germany and reveals the necessity for networking among attending physicians in order to implement guidelines-conformed treatment.
