The objective was to externally validate the ability of the San Francisco Syncope Rule (SFSR) to accurately identify patients who will experience a 7-day serious clinical event in an Asian population. ⋯ In this study, SFSR rule had a sensitivity of 94.2%. This suggests caution on the strict application of the rule to all patients presenting with syncope. It should only be used as an aide in clinical decision-making in this population.

In the face of increasing volume of emergency department (ED) patients with primary psychiatric illness and increasing length of stay (LOS), a department of psychiatry initiated a program whereby faculty members of the department of psychiatry from a hospital conducted rounds in the ED each weekday on these patients. ⋯ Weekday rounds in the ED by psychiatry faculty are associated with a reduction in the LOS for psychiatric patients, mainly due to reduced LOS of those patients with the longest stays.

Recombinant tissue plasminogen activator (rt-PA) is a lytic medication widely used in the emergency department to treat acute thrombotic disorders such as ischemic stroke and myocardial infarction. It is known in the clinical use of this drug that it can be less effective in approximately 25% of individuals receiving such treatment. However, there are no data on the variation of lytic efficacy of rt-PA in decreasing individuals' clot size over time. In this study, in vitro lytic efficacy was determined by measuring the decrease in clot diameter after 30 minutes of drug exposure. The authors sought to explore whether there are individuals who do not respond to this lytic therapy and to estimate the rate of nonresponse. ⋯ Overall, rt-PA does not produce clot lysis in vitro in clots from a substantial minority of the population, likely due to individual variations in clot composition and structure.

Emergency department (ED) computed tomography (CT) use has increased significantly during the past decade. It has been suggested that adherence to clinical decision support (CDS) may result in a safe decrease in CT ordering. In this study, the authors quantified the percentage agreement between routine and CDS-recommended care and the anticipated consequence of strict adherence to CDS on CT use in mild traumatic brain injury (mTBI). ⋯ There is a 60% to 80% agreement between routine and CDS-recommended head CT use. Of the three CDS systems examined, the only one that may result in a reduction in head CT use if strictly followed was the Canadian head CT CDS. Further studies are needed to examine reasons for the less than optimal agreement between routine care and care recommended by the Canadian head CT CDS.
