ABSTRACTIntroduction:Venous thromboembolism (VTE) is difficult to diagnose yet potentially life threatening. A low-risk pretest probability (PTP) assessment combined with a negative D-dimer can rule out VTE in two-thirds of outpatients, reducing the need for imaging. Real-life implementation of this strategy is associated with several challenges. ⋯ Conclusion:In spite of excellent compliance with our algorithm, we were unable to reduce imaging for VTE. This may be due to a lower threshold for suspecting VTE and an increase in investigation for VTE combined with a high false positive rate of our D-dimer assay in low-pretest probability patients. This study highlights two common real-life challenges with adopting this strategy for VTE investigation.

A 51-year-old man presented with a 5-day history of progressive facial swelling, sensation of head fullness, increasing shortness of breath and paroxysmal nocturnal dyspnea. He denied chest pain, syncope or presyncope. Past medical history included mechanical aortic valve replacement 7 years prior and atrial fibrillation treated with warfarin. ⋯ Acute type A aortic dissection (AD) is an emergency requiring prompt diagnosis and treatment. Patients typically present with acute onset of chest and/or back pain, classically described as "ripping" or "tearing." SVC syndrome is rarely, if ever, mentioned as a presentation, as it is usually due to more chronic conditions. This case illustrates a rare incidence of type A AD actually presenting as SVC syndrome.

ABSTRACTObjective:To define the range of clinical conditions Canadian emergency pediatricians consider appropriate for management by physician assistants (PAs) and the degree of autonomy PAs should have in the pediatric emergency department (PED). Methods:We conducted a cross-sectional, pan-Canadian survey using electronic questionnaire technology: the Active Campaign Survey tool. We targeted PED physicians using the Pediatric Emergency Research Canada (PERC) network database (N = 297). ⋯ For the remaining 33 clinical conditions, more than 85% of respondents felt that PA could appropriately manage but were divided between requiring direct and only indirect physician supervision. Respondents' selection of the number of conditions felt to be appropriate for PA involvement varied between the size of the emergency department (ED) in which they work (larger EDs 87.7-89.1% v. smaller EDs 74.2%) and familiarity with the clinical work of PAs in the ED (90.5-91.5% v. 82.2-84.7%). Conclusion:This national survey of Canadian PED physicians suggests that they feel PAs could help care for a large number of nonemergent clinical cases coming to the PED, but these clinical encounters would have to be directly supervised by a physician.

ABSTRACTObjectives:Emergency departments (EDs) are recognized as a high-risk setting for prescription errors. Pharmacist involvement may be important in reviewing prescriptions to identify and correct errors. The objectives of this study were to describe the frequency and type of prescription errors detected by pharmacists in EDs, determine the proportion of errors that could be corrected, and identify factors associated with prescription errors. ⋯ Factors associated with prescription errors were patient age over 65 (odds ratio [OR] 2.34; 95% CI 1.32-4.13), prescriptions with more than one medication (OR 5.03; 95% CI 2.54-9.96), and those written by emergency medicine residents compared to attending emergency physicians (OR 2.21, 95% CI 1.18-4.14). Conclusions:Pharmacists in a tertiary ED are able to correct the majority of prescriptions in which they find errors. Errors are more likely to be identified in prescriptions written for older patients, those containing multiple medication orders, and those prescribed by emergency residents.
