Introduction: The Ottawa SAH Rule was developed to identify patients at high-risk for subarachnoid hemorrhage (SAH) who require investigations and the 6-Hour CT Rule found that computed tomography (CT) was 100% sensitive for SAH 6 hours of headache onset. Together, they form the Ottawa SAH Strategy. Our objectives were to assess: 1) Safety of the Ottawa SAH Strategy and its 2) Impact on: a) CTs, b) LPs, c) ED length of stay, and d) CT angiography (CTA). Methods: We conducted a multicentre prospective before/after study at 6 tertiary-care EDs January 2010 to December 2016 (implementation July 2013). Consecutive alert, neurologically intact adults with a headache peaking within one hour were included. SAH was defined by subarachnoid blood on head CT (radiologists final report); xanthochromia in the cerebrospinal fluid (CSF); >1 x 106/L red blood cells in the final tube of CSF with an aneurysm on CTA. Results: We enrolled 3,669 patients, 1,743 before and 1,926 after implementation, including 185 with SAH. The investigation rate before implementation was 89.0% (range 82.9 to 95.6%) versus 88.4% (range 85.2 to 92.3%) after implementation. The proportion who had CT remained stable (88.0% versus 87.4%; p = 0.60), while the proportion who had LP decreased from 38.9% to 25.9% (p < 0.001), and the proportion investigated with CTA increased from 18.8% to 21.6% (p = 0.036). The additional testing rate (i.e. LP or CTA) diminishedfrom 50.1% to 40.8% (p < 0.001). The proportion admitted declined from 9.8% to 7.3% (p = 0.008), while the mean length of ED stay was stable (6.2 +/− 4.0 to 6.4 +/− 4.1 hours; p = 0.45). For the 1,201 patients with CT 6 hours, there was an absolute decrease in additional testing (i.e. LP or CTA) of 15.0% (46.6% versus 31.6%; p < 0.001). The sensitivity of the Ottawa SAH Rule was 100% (95%CI: 98-100%), and the 6-Hour CT Rule was 95.3% (95%CI: 88.9-98.3) for SAH. Five patients with early CT had SAH with CT reported as normal: 2 unruptured aneuryms on CTA and presumed traumatic LP (determined by treating neurosurgeon); 1 missed by the radiologist on the initial interpretation; 1 dural vein fistula (i.e. non-aneuyrsmal); and 1 profoundly anemic (Hgb 63g/L). Conclusion: The Ottawa SAH Strategy is highly sensitive and can be used routinely when SAH is being considered in alert and neurologically intact headache patients. Its implementation was associated with a decrease in LPs and admissions to hospital. Introduction: Gastroenteritis accounts for 1.7 million emergency department visits by children annually in the United States. We conducted a double-blind trial to determine whether twice daily probiotic administration for 5 days, improves outcomes. Methods: 886 children aged 348 months with gastroenteritis were enrolled in six Canadian pediatric emergency departments. Participants were randomly assigned to twice daily Lactobacillus rhamnosus R0011 and Lactobacillus helveticus R0052, 4....

CanadiEM: Accessing a Virtual Community of Practice to Create a Canadian National Medical Education Institution

“…At CanadiEM, the facilitated interactions between team members in our community of practice have developed an identity that values national collaboration on high‐quality scholarship. Our community has produced more than a half‐dozen nationally presented posters and presentations and four traditional academic publications . As CanadiEM has become an established leader in FOAM, we have begun to spearhead the online recruitment efforts of study participants and to support research on FOAM projects …”

Exploring Factors Affecting Physical Health Perception Through Sports Participation: A PLS-SEM Approach

“…This social relationship sometimes becomes a turning point for someone to show their best performance in sports. Highlighting self-identity to maintain social relationships in sports teams can contribute to greater enjoyment of sports and reduce feelings of hopelessness in sports (Huang et al, 2018). Other research shows that the benefits of sports participation for young people in society are generally becoming more realistic (Bailey, 2005).…”
