Admission rates and expenditures for syncope remain high. This unsatisfactory management could be due to several factors, including lack of evidence-based strategy, poor accuracy of clinical decision rules, difficulty in disseminating guidelines, as well as uncertainties concerning management of intermediate-risk patients and role of observation protocols and syncope units. To optimise management, it has been proposed to adopt a pragmatic, symptoms-based definition of syncope and a classification related to the underlying mechanism rather than suspected aetiology. It has also been emphasised the importance of identifying patients at intermediate risk as they can be safely discharged after an intensive emergency department evaluation. A further improvement might result from a research implementation to validate the role of observation protocols and to select patients amenable to be sent to outpatient syncope units. Finally, future studies on prognostic significance of syncope should be performed with a more careful selection of outcomes and a greater uniformity.
