A simple bedside test, the Dix-Hallpike test (DHT), can reliably diagnose benign paroxysmal positional vertigo (BPPV) in patients with acute onset dizziness or vertigo. We evaluated patterns of DHT use by emergency physicians in patients presenting with dizziness and vertigo. Our objective was to assess the frequency and clinically appropriate use of the DHT in an emergency department. ⋯ The DHT is both underutilized and frequently applied to patients whose symptoms are not consistent with BPPV. This may result in prolonged patient discomfort and increased resource utilization, as well as increasing the risk of misdiagnosing central vertigo.

Observational Study
The association between monthly social assistance disbursement days and emergency department visits for trauma, mental health, and substance use.
Social assistance helps fulfill the basic needs of low-income individuals. In British Columbia, social assistance is issued on the third or fourth Wednesday of every month. However, this sudden influx of resources may have negative health consequences. We investigated social assistance timing and emergency department (ED) visits related to trauma, mental health, and substance use. ⋯ Social assistance disbursement is followed by an increase in mental health and substance-related ED presentations and may be associated with an increase in trauma presentations on the day of cheque disbursement. These findings support calls for clinical and policy-level changes and support to reduce cheque day-associated harm.

Early surgical intervention is increasingly employed for patients with ureteral colic, but guidelines and current practice are variable. We compared 60-day outcomes for matched patients undergoing early intervention vs. spontaneous passage. ⋯ In matched patients with 2.0-9.9 mm ureteral stones, early intervention was associated with similar rates of treatment failure but greater patient morbidity, evidenced by hospitalizations and emergency revisits. Physicians should adopt a selective approach to interventional referral and consider that spontaneous passage probably provides better outcomes for many low-risk patients.
