Health care and cost of medication for inflammatory bowel disease in the Rhein-Main region, Germany: a multicenter, prospective, internet-based study.

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.

[Effectiveness of antiviral therapy in patients with chronic hepatitis C treated by private practice gastroenterologists]. / Effektivität der antiviralen Behandlung von Patienten mit chronischer Hepatitis C in der gastroenterologischen Facharztpraxis.

The standard treatment for patients with chronic hepatitis C consists of pegylated interferon (PegIFN) alpha in combination with ribavirin. Information on treatment effectiveness outside clinical trials is sparse. To study community-based health care, a regional network supported by the German network of competence for hepatitis (Hep-Net) was created between gastroenterologists in private practice and a tertiary referral centre. A treatment register containing evidence-based guidelines was established and 212 consecutive patients who were treated with either PegIF Nalpha 2a/ribavirin (n = 126) or PegIFNalpha2b/ribavirin (n = 86) for 24 weeks (HCV genotype 2, 3) and 48 weeks (HCV genotype 1, 4, 5), respectively, were included and followed prospectively. Twenty-four weeks after cessation of antiviral treatment a sustained virological response was achieved in 54 % of the patients. By univariate analyses, infection with HCV genotypes 2 or 3 (p < 0.0001), younger age (p < 0.0001), normal gamma-glutamyltransferase levels before initiation of treatment (p = 0.003), and absence of language communication problems (p = 0.023) were associated with a sustained virological response. The presence of liver cirrhosis in patients with HCV genotype 1, 4, 5 infection was associated with lower sustained response rates (p = 0.025). Patients infected with HCV genotype 1 in whom the PegIFNalpha dose was reduced had higher virological relapse rates (p = 0.049). With regard to the treating physician, sustained virological response rates ranged from 26 - 67 % in patients infected with HCV genotype 1. Our study shows that virological response rates similar to those in international randomised clinical trials can be achieved by private practice gastroenterologists. The presented network allows characterization of the treatment outcome in chronic hepatitis C not only with regard to virus- and host-related factors but also on an individual physician basis.
