Background Information: The presentation of a patient with syncope to the Emergency Department (ED) can pose a challenge to clinicians as the identification of a serious underlying condition is the priority. Often the original cause of the syncope is difficult to determine in the ED and ultimately results in unnecessary hospitalization. Of all syncope patients evaluated in the ED, 3-5% of them will be found to have a serious condition after ED disposition.1 Furthermore, the literature has shown that hospital admissions due to syncope were associated with low mortality or the need for procedures.2 Emergency physicians are then also posed with the task of determining which patients may be considered low, medium and high risk for a serious outcome. Several risk stratification tools have been developed to help with the identification of these patients, however many of these tools are not validated and very complex, therefore they are not used clinically. The Canadian Syncope Risk Score (CSRS) is among these decision tools, however it has yet to be validated. The authors of this paper sought to conduct a multicenter ED based prospective study to validate this tool and advocate its superior use over some of the other risk stratification tools that currently exist.

Take Home Points

  • There is no real distinction between syncope and near syncope.

  • Older folk with near syncope or syncope should be treated the same.

  • Patient with high risk features its reasonable to admit but if they’re low risk, well-appearing and have reasonable follow up discharge home is fine.

Background Information: Syncope is defined as a sudden transient loss of consciousness (LOC) followed by complete resolution. It represents 1-3% of all emergency department (ED) visits. 1 1% of all hospitalizations are due to syncope as it may have resulted from a serious underlying condition, such as arrhythmia, acute cardiac ischemia, pulmonary embolism or internal hemorrhage. 2,3 Prior studies have demonstrated that up to a half of these serious conditions, particularly arrhythmias, are missed during ED evaluation and become evident after disposition. 1 Several risk stratification tools, such as the Canadian Syncope Risk Score (CSRS; Figure 1) and the San Francisco Syncope Rule (SFSR; Figure 2) have been developed to help identify serious outcomes. 4,5 The authors of this study sought to describe the time to occurrence of serious arrhythmias relative to when the patient arrived in the ED and based on their CSRS risk category. Furthermore, their goal was to use the results of this study to provide guidance for decision making regarding duration and location of cardiac monitoring.

Background: Syncope, defined as a transient loss of consciousness with spontaneous and complete recovery to pre-event status, is a common emergency department (ED) presentation. Recently, we have discussed the lack of clinical utility in distinguishing syncope from near-syncope in terms of outcomes. In that discussion, we concluded: “In older adults (> 60 years of age), near-syncope appears to portend an equal risk of death or serious clinical event at 30 days when compared to syncope. These two entities should be considered as one when decisions are made in terms of evaluation in the ED.” While we argue for evaluation and disposition to be the same, we don’t address what the best disposition or plan is. While it is common to admit older patients with syncope/near-syncope from the ED, admission doesn’t inherently yield better outcomes.
