Integrated Care for Crohn's Disease: A Plea for the Development of Clinical Decision Support Systems

Evolution in the management of Crohn's disease [CD] has been characterized by recent paradigm changes. First, new biological therapies induce intestinal healing and full disease control in a substantial number of patients, particularly when introduced early in the disease course. However, they are expensive and associated with potentially severe side effects, raising the question of optimal treatment duration. Secondly, progress in biomarkers and medical imaging performance has enabled better refinement of the definition and prediction of remission or relapse of the disease through monitoring [tight control]. This progress may help to improve tailoring treatment in relation to target ['treat-to target' approach], applying patient-centred and collaborative perspectives, consistent with other chronic disease management. Such an approach requires the integration of a potentially large number of parameters coming from different stakeholders. This integration would be difficult based solely on implementation of classical guidelines and the clinician's intuition. To this end, clinical decision support systems should be developed that integrate a combination of various outcomes to facilitate the treatment decision and to share information between patients, primary care specialists, and health insurance companies or health authorities. This should ease complex therapeutic decisions and serve as a basis for continued research into effectiveness of CD management.
