Things We Do For No Reason: Echocardiogram in Unselected Patients with Syncope.

Syncope is a common cause of emergency department visits and hospitalizations. Echocardiogram is frequently used as a diagnostic tool in the evaluation of syncope, performed in 39% to 91% of patients. The diagnostic yield of echocardiogram for detecting clinically important abnormalities in patients with a normal history, physical examination, and electrocardiogram (ECG), however, is extremely low. In contrast, echocardiograms performed on patients with syncope with a positive cardiac history, abnormal examination, and/or ECG identify an abnormality in up to 29% of cases, though these abnormalities are not always defi nitively the cause of symptoms. Recently updated clinical guidelines for syncope management from the American College of Cardiology now recommend echocardiogram only if initial history or examination suggests a cardiac etiology, or ECG is abnormal. Universal echocardiography in patients with syncope exposes a signifi cant number of patients to unnecessary testing and cost and does not represent evidence-based or high-value patient care.

Youth tobacco access restrictions: Time to shift resources to other interventions?

There is limited data to guide policy makers as to whether youth tobacco access restriction is an effective strategy. Analysis of the limited data on youth access restriction suggests that (a) scalable models for access restriction are lacking, (b) enforcement of access restriction would be cost prohibitive, (c) the leaky commercial supply of cigarettes combined with the capacity of youth to tap into a "social supply" of cigarettes would hamper all but the most rigorously enforced efforts to restrict access to tobacco, and (d) access restriction may paradoxically increase allure of cigarettes for some youth. Although youth tobacco access restriction does not face strong political or industry opposition, the authors' analysis reveals that youth tobacco access restriction is likely to remain a failed strategy to control tobacco use in the United States.
