Creation of a Syncope Channel for Patients Admitted to the Emergency Department for Loss of Consciousness and Not Hospitalized: Etiological Predictivity (Before/After Study)

The main aim of this study is to assess the value of creating a "syncope pathway" to optimize diagnostic performance in patients admitted to the emergency department for syncope and not hospitalized, compared with the previous pre-syncope pathway situation.

Inclusion Criteria:

• Adults aged 18 and over;

• Consultant at the emergency department of the Centre Hospitalier de V ersailles

• For a confirmed diagnosis:

• of recurrent syncope with low-risk criteria according to ESC 2018 (1,2) Or

• of syncope recurrent or not, not fulfilling low-risk or high-risk criteria according to the ESC 2018 definition (1,2). These patients are those with minor high-risk criteria without aggravating circumstances:

  • With no personal history of loss of consciousness whose clinical features strongly suggest syncope of rhythmic origin;
  • No structural heart disease or abnormal ECG.

• Outpatient (returning home after emergency);

• Beneficiary or beneficiary of a social security scheme (excluding AME).

Exclusion Criteria:

• Etiology of syncope identified as early as the emergency department visit;
• High-risk syncope according to ESC 2018 criteria (1,3);
• First and only episode of low-risk syncope according to ESC 2018 criteria (1,3);
• Syncope of any risk category requiring hospitalization at the discretion of the emergency physician and cardiologist;
• Legal protection by guardianship ;
• Language barrier or condition incompatible with the patient's understanding or informed adherence to the protocol;
• Opposition to the use of their pseudonymized data (for retrospective inclusions);
• Patient's refusal to give consent to participate in the study (for prospective inclusions);
