- ABSTRACT: Objective: Syncope accounts for 1% of emergency department (ED) visits, yet few experience a serious adverse event (SAE). Two-thirds of syncope patients are transported to the ED by ambulance, placing considerable burden on emergency medical services (EMS), and many of these transports may be unnecessary. We estimated the proportion of syncope patients who fell into a low-risk category based on an ED diagnosis of vasovagal syncope and the absence of EMS intervention, hospitalization, or SAE. Methods: We conducted a multicentre prospective cohort study enrolling adult syncope patients transported to the ED by ambulance over 13 months. We collected demographics and EMS interventions, and followed patients for 30 days to identify all SAE, including death, dysrhythmia, myocardial infarction, aortic dissection, pulmonary embolism, subarachnoid hemorrhage, significant hemorrhage, and related procedural interventions. Results: Of 990 (67.2%) patients transported to the ED by ambulance, 121 had EMS interventions, 137 suffered 30-day SAE, 393 (39.7%; 95%CI 36.6, 42.8) were deemed low risk, 41 patients with vasovagal syncope were lost to follow-up, and 298 patients were diagnosed with non-vasovagal syncope. During transport, 121 (12.2%; 95%CI 10.2, 14.3) patients underwent some EMS intervention, and 137 (14.6%; 95%CI 12.4, 16.9) suffered SAEs within 30 days. Conclusion: About 40% of patients transported to the ED by ambulance are at low risk and may not benefit fromABSTRACT: Objective: Syncope accounts for 1% of emergency department (ED) visits, yet few experience a serious adverse event (SAE).

Conclusion: About 40% of patients transported to the ED by ambulance are at low risk and may not benefit from paramedic care or transport to a hospital. A robust clinical decision tool would help identify patients safe for treat-and-release, diversion to alternative care, or rapid offload into low-acuity ED areas, potentially reducing EMS workload and cost. RÉSUMÉ: Objectif: Les syncopes motivent 1 % des consultations au service des urgences (SU), mais le malaise entraîne peu d'événements indésirables graves (EIG). Ainsi, deux tiers des patients ayant subi une syncope sont transportés en ambulance au SU, ce qui impose un lourd fardeau sur les services médicaux d'urgence (SMU), et pourtant bon nombre de transports effectués seraient non nécessaires. Aussi l'étude visait-elle à estimer la proportion de patients ayant subi une syncope dont l'état serait jugé à faible risque d'après le diagnostic de syncope vasovagale posé au SU ainsi que d'après l'absence d'intervention faite par les SMU, d'hospitalisation ou d'EIG. Méthode: Il s'agit d'une étude prospective de cohortes, multicentrique, menée chez des adultes qui ont subi une syncope et qui ont été transportés en ambulance au SU, sur une période de 13 mois. Ont été recueillies des données démographiques ainsi que les notes sur les interventions effectuées par les SMU; à cela s'ajoute un suivi de 30 jours aux fins de collecte de renseignements sur tout EIG : mort, arythmie, infarctus du myocarde, dissection de l'aorte, embolie pulmonaire, hémorragie sous-arachnoïdienne, hémorragie importante et gestes interventionnels liés aux troubles en question. Résultats: Au total, 990 patients (67, 2 %) ont été transportés en ambulance au SU; sur ce nombre, 121 ont subi des interventions pratiquées par les SMU; 137 ont connu un EIG au cours des 30 jours suivant le malaise; 393 (39, 7 %; IC à 95 % : 36, 6-42, 8) ont été jugés à faible risque; 41 ayant fait une syncope vasovagale ont été perdus de vue durant le suivi; et 298, ont fait une syncope non vasovagale. Durant le transport, 121 patients (12, 2 %; IC à 95 % : 10, 2-14, 3) ont subi une forme quelconque d'intervention par les SMU et, au cours des 30 jours de suivi, 137 (14, 6 %; IC à 95 % : 12, 4-16, 9) ont connu un EIG. Conclusion: Environ 40 % des patients transportés en ambulance au SU connaissent un faible risque et, dans leur cas, la prestation de soins paramédicaux ou le transport à l'hôpital pourraient ne pas être nécessaires. Un outil d'aide à la décision clinique qui soit digne de confiance pourrait faciliter le repérage des patients dont l'état se prêterait au traitement suivi du congé, à une orientation vers d'autres types de soins ou à un passage rapide dans des zones de petites urgences, ce qui permettrait à la fois de réduire la charge de travail des SMU ainsi que les coûts. … (more)
