Meta Analysis
The diagnostic accuracy of a point-of-care ultrasound protocol for shock etiology: A systematic review and meta-analysis.
The aim of this study was to perform a systematic review and meta-analysis of the diagnostic accuracy of a point-of-care ultrasound exam for undifferentiated shock in patients presenting to the emergency department. ⋯ The rapid ultrasound for shock and hypotension (RUSH) exam performs better when used to rule in causes of shock, rather than to definitively exclude specific etiologies. The negative likelihood ratios of the exam by subtype suggest that it most accurately rules out obstructive shock.

The Canadian Stroke Best Practice Recommendations suggests that patients suspected of transient ischemic attack (TIA)/minor stroke receive urgent brain imaging, preferably computed tomography angiography (CTA). Yet, high requisition rates for non-cerebrovascular patients overburden limited radiological resources, putting patients at risk. We hypothesize that our clinical decision support tool (CDST) developed for risk stratification of TIA in the emergency department (ED), and which incorporates Canadian guidelines, could improve CTA utilization. ⋯ Our CDST could enhance CTA utilization in the ED for suspected TIA patients, and facilitate guideline-based stroke care. Use of our CDST would increase the number of TIA patients receiving CTA before ED discharge (rather than later at TIA units) and reduce the burden of imaging stroke mimics in radiological departments.

Patients suffering from an out-of-hospital cardiac arrest (OHCA) associated with an initial shockable rhythm have a better prognosis than their counterparts. The implications of recurrent or refractory malignant arrhythmia in such context remain unclear. The objective of this study is to evaluate the association between the number of prehospital shocks delivered and survival to hospital discharge among patients in OHCA. ⋯ Survival remains possible even after a high number of shocks for patients suffering from an OHCA with an initial shockable rhythm. However, requiring more shocks is independently associated with worse survival.

Emergency medicine residents may be transitioning to practice with minimal training on how to supervise and assess trainees. Our study sought to examine: 1) physician comfort with supervision and assessment, 2) what the current training gaps are within these competencies, and 3) what barriers or enablers might exist in implementing curricular improvements. ⋯ As programs transition to competence by design, there will be a need for formal training in supervision and assessment, with a focus on negative feedback, to achieve a standardized level of competence among emergency physicians.

Patients often bring their smartphones to the emergency department (ED) and want to record their procedures. There was no clear ED recording policy in the Saskatoon Health Region nor is there in the new Saskatchewan Health Authority. With limited literature on the subject, clinicians currently make the decision to allow/deny the request to record independently. The purpose of this study was to examine and compare patient and clinician perspectives concerning patients recording, in general, and recording their own procedures in the ED. ⋯ Contrary to patients' views, clinicians were not in favour of allowing audio or video recordings in the ED. Concerns around consent, staff and patient privacy, and legal issues warrant the development of a detailed policy if the decision is made in favour of recording.
