The diagnosis of IBS in primary care: consensus development using nominal group technique

Abstract

The basis of IBS diagnosis in primary care differs from, and is less exclusive than, existing criteria. Few features are deemed essential for diagnosis, while psychosocial features, patient characteristics and contextual factors are important in increasing diagnostic probability. There are important cultural differences in the description of key symptoms. These results provide information on the defining characteristics of IBS and the diagnostic process, as it occurs in primary care, and can guide clinical practice.
