Item does not contain fulltext BACKGROUND: Inflammatory bowel disease (IBD) care and education might differ around Europe. Therefore, we conducted this European Variation In IBD PracticE suRvey (VIPER) to investigate potential differences between countries. METHODS: This trainee-initiated survey, run through SurveyMonkey®, consisted of 47 questions inquiring basic demographics, IBD training, and clinical care. Results were compared according to gross domestic product (GDP) per capita, for which countries were divided into 2 groups (low/high income, according to the World Bank). RESULTS: The online survey was completed by 1,285 participants from 40 European countries, with a majority of specialists (65.3%) working in academic institutions (50.4%). Significant differences in IBD-specific training (55.9% vs. 38.4%), as well as availability of IBD units (58.4% vs. 39.7%) and multidisciplinary meetings (73.2% vs. 40.1%), were observed between respondees from high and low GDP countries (p < 0.0001). In high GDP countries, IBD nurses are more common (85.9% vs. 36.0%), also mirrored by more nurse-led IBD clinics (40.6% vs. 13.7%; p < 0.0001). IBD dieticians (33.4% vs. 16.5%) and psychologists (16.8% vs. 7.5%) are mainly present in high GDP countries (p < 0.0001). In the current COVID era, telemedicine is available in 73.2% versus 54.1% of the high/low GDP countries, respectively (p < 0.0001). Treat-to-target approaches are implemented everywhere (85.0%), though access to biologicals and small molecules differs significantly. CONCLUSION: Much variability in IBD practice exists across Europe, with marked differences between high and low GDP countries. Further work is required to help address some of these inequalities, aiming to improve and standardize IBD care and training across Europe.

Background and objectives Primary biliary cholangitis (PBC) is an autoimmune disease that affects the small bile ducts. The only treatments currently approved in our country are ursodeoxycholic acid (UDCA) and obeticholic acid. Different indices evaluate the response after 1 year of treatment. The aim of our study was to evaluate the different predictive scores and prognostic factors of response to UDCA. Material and methods Retrospective single-centre study in which clinical and analytical data of patients diagnosed with PBC were collected from January 1987 to December 2015. The response after 1 year of treatment was evaluated using the different response scores and their concordance degree using the Kappa index. The area under the receiver operating characteristic curve (AUROC) was calculated to determine the predictive capacity of the scores. Likewise, the prognostic factors of response to treatment were analysed. Results We included 153 patients. The bivariate analysis showed a statistically significant relationship between the initial high levels of alkaline phosphatase and cholesterol and the poor response to treatment. The best AUROC was in Paris-I score (0.81). The concordance between the different scores was low. The GLOBE score was valid to evaluate the prognosis. Conclusion Basal alkaline phosphatase and cholesterol were predictors of poor outcome. The best predictive qualitative score in our cohort patients was Paris-I. There was a poor concordance between the different predictive scores. GLOBE score is valid to evaluate prognosis.

Background Heterogeneity in the treatment of a disease is a marker of suboptimal quality of care. Recent studies suggest that there is a marked heterogeneity in the management of inflammatory bowel disease. The aim of this study is to evaluate the heterogeneity in the treatment used and the outcomes (rate of hospitalization and surgery) for Crohn’s disease (CD) in the different health areas of Catalonia. Methods All patients with CD included in the Catalan Health Surveillance System (CHSS) including data on more than 7 million individuals from 2011 to 2017 were identified using with the ICD-9-CM codes. The different Catalonian health areas were grouped into 19 groups according to the reference hospital (figure 1). Exposures to different treatments were retrieved from the electronic dispensation records. Data on hospitalizations and surgeries were also extracted from the CHSS according to ICD-9-CM codes. Treatment used rates (systemic corticosteroids, non-biological and biological immunosuppressant) and outcome rates (hospitalization and surgery) were calculated. Results The use of systemic corticosteroids presented a decreasing trend over the study period, with an average rate of use of the total number of patients in the different territories between 10% and 16% (figure 2). The use of non-biological immunosuppressant treatment has remained stable, with an average rate of use ranging from 20% to 40% (figure 3). On the other hand, the use of biological immunosuppressant treatment increased, with an average rate of use in the different territories ranging from 10 to 22% (figure 4). Hospitalizations for any reason showed an increasing trend between 2011–2017 with an average rate between 19% and 30% per year depending on the area. Contrarily, hospitalizations for CD presented a decreasing trend, with an average rate between 5% and 10% per year. Surgical treatment (both resections and ostomies) remained stable over time. Rates per year were between 1% and 2%. Conclusion In this population study we appreciated an important heterogeneity in the use of non-biological and biological immunosuppressant treatments, identifying use rates of almost the double in some of the areas. There is also a remarkable variability in the rate of hospitalizations for CD between certain areas of Catalan territory.

Background Data from clinical trials suggest that biological drugs may improve the outcomes in Crohn’s disease (CD) by reducing the need for surgery or hospitalisation. However, data on the trends in biological drug use and outcomes in CD patients are scarce. The aim of this study is to evaluate the time-trends of the use of biological drugs and other treatments for CD, and its relationship with outcomes such as surgery and hospitalisation in Catalonia. Methods All patients with CD included in the Catalan Health Surveillance System (containing data on a population of more than 7.5 million) from 2011 to 2017 were identified. The exposures to different treatments for inflammatory bowel disease were retrieved from electronic invoicing records. Time trends for surgery and hospitalisation were described and tested for correlation with treatment using the statistical package R, version 3.4.3. Results Between 2011 and 2017, the use of salicylates, corticosteroids and immunosuppressive treatment fell from 28.8% to 17.1%, 15.8% to 13.7%, and 32.9% to 29.6%, respectively. Biological treatment use rose from 15.0% to 18.7%. Adalimumab was the most frequently prescribed biologic (1604 patients; 52% of all biologics in 2017). Ostomy rates per 1000 patients/year fell from 13.2 in 2011 to 9.8 in 2017, and surgical resection rates from 24.1 to 18.0. The rate of CD-related hospitalisations per 1000 patients/year also fell, from 92.7 to 72.2. Conclusion Biological drug use rose from 15.0% to 18.7% between 2011 and 2017. During the same period, we observed an improvement in the outcomes of CD patients.
