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.

Emergency medicine (EM) is emerging worldwide. Its development as a recognized specialty is proceeding at difference rates in different countries. Europe is a region with complex political affiliations and is composed of countries both within and outside the European Union (EU). ⋯ The European Union of Medical Specialists requires that once two-fifths of countries acknowledge a specialty, all EU countries must address the question. EM had achieved the needed majority by 2011. This article briefly describes the European road to specialty acceptance.

Patients sustaining rattlesnake envenomation often develop thrombocytopenia, the etiology of which is not clear. Laboratory studies have demonstrated that venom from several species, including the Mojave rattlesnake (Crotalus scutulatus scutulatus), can inhibit platelet aggregation. In humans, administration of crotaline Fab antivenom has been shown to result in transient improvement of platelet levels; however, it is not known whether platelet aggregation also improves after antivenom administration. ⋯ Crotaline Fab antivenom improved platelet aggregation in an in vitro model of platelet dysfunction induced by venom from C. scutulatus. It is unclear at this time whether this improvement in platelet dysfunction translates into improved clinical outcomes in envenomated patients.
