An international validation study found that the Canadian Syncope Risk Score (CSRS) showed good performance in the identification of patients at low risk for serious outcomes and, therefore, could potentially be discharge from the emergency department (ED). While the CSRS was also found to be superior to the Osservatorio Epidemiologico sulla Sincope nel Lazio (OESIL) risk score, its clinical utility remains uncertain without further research. The findings are published in Annals of Internal Medicine.
