performed a cross-sectional survey with 300 respondents (n = 153 English and n = 147 Arabic). Outcome Measures and Analysis: Emergent themes show that Facebook use appears to influence older female Arab adults who push certain food choices on their children as a result. Facebook provides a platform for unhealthy food advertising and inaccurate information sharing, and is a primer of intake of certain food items and mixes. A difference in the demographic profile is noted between participants who chose to respond to the survey in English over Arabic. While the majority were female (at least 80% and above), those who answered in English were 58% millennials, 60% university graduates, 58% married, and 69% employed compared to those who answered in Arabic: 34% Generation X, 29% millennials, 49% university graduates, 51% married, and 51% unemployed. Results: Results of linear regression primarily show that the average F scores statistically significantly predicted Exposure to Nutrition Misinformation (EtNM) scores, F (1,74) = 11.338, P = .001, accounting for 13.3% of the variation in EtNM score with adjusted R2 = 12.1%. Increase in F score leads to 0.273 EtNM score, 95% CI [0.111, 0.434] increase in EtNM score. Conclusions and Impolications:We conclude that exposure to nutrition misinformation is related to Facebook use. Future interventions to correct for nutrition misinformation on Facebook is warranted. Funding: None.
Introduction: Emergency medicine clinicians (physicians, nurses, paramedics, physician assistants) utilize podcasts for learning. However, their versatility produces variability in the ways they are used (e.g. their speed can be increased or decreased, unrelated activities can be performed simultaneously, or they can be accompanied by active learning methods). This study investigated how and why podcasts are used by an international cohort of clinicians. Methods: An international sample of medical students, residents, physicians, nurses, physician assistants, and paramedics was recruited to complete a survey hosted on FluidSurveys software using social media (Twitter and Facebook), direct contact from our international authorship group, infographics, and a study website (https://METRIQstudy.org/). Participants who indicated interest in the study were sent an email containing the study survey. Reminder emails were sent every 5-10 days a maximum of three times. Results: 462 clinicians expressed interest and 397 completed the survey (86.0% completion rate). Participants hailed from 34 countries (38.8% Canada, 30% United States, 31.2% outside of North America) and a majority (61.9%) were physicians. Approximately half (45.8%) of the participants listened to podcasts weekly. Podcasts were used to learn core material (75.1%), refresh memory (72.3%), or review new literature (75.8%). Most listened on iPhones (61%) and the native Apple App (66.1%). The preferred Android apps were Pocket Casts (22.8%) and Google Play (18.5%). Many listened to podcasts while driving (72.3%). Active learning techniques such as pausing, repeating segments, taking notes, or listening to a podcast more than once were rarely used (1/4 of the time or less) by the majority of participants. Conclusion: This study describes how and why medical education podcasts are used by emergency medicine clinicians and should inform both podcast producers and future research investigating the impact of various listening habits on retention. Further analysis of the data will elucidate differences in listening habits

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....
Innovation Concept: Canadian medical students completing their Emergency Medicine (EM) clerkship rotations must develop approaches to undifferentiated patients. Increasingly used in postgraduate EM education, Open Educational Resources (OERs) are a convenient and flexible solution to meeting medical student educational needs on their EM rotation. We hoped to supplement Canadian medical student EM education through the development of ‘ClerkCast’, a novel OER and podcast-based curriculum on CanadiEM.org. Methods: We utilized the Kern Six Step approach to curriculum development for ‘ClerkCast’. A general needs assessment involved a review of available OERs and identified a lack of effective EM OERs specific for medical students. A specific online needs assessment was used to determine which EM topics required further education for medical students. The survey was shared directly with key Canadian medical student and undergraduate medical educator stakeholder groups, and distributed globally through the CanadiEM social media networks. Results of the needs assessment highlighted shared perceptions of educational needs for medical students, with an emphasis on increased need for education on critical care and common EM presentations. We used the topics determined to be highest priority for the development of our first ten episodes of ‘ClerkCast’. Curriculum, Tool or Material: Podcast episodes are released from CanadiEM biweekly. Episodes are 30 to 45 min in length, and focus on cognitive approaches to a common EM presentation for medical students. Content is anchored on medical student interactions with a staff or resident EM co-host. Podcasts are supplemented by infographics and blog posts highlighting the key points from each episode. Learners are also encouraged to interact with the content through review quizzes on a provided question bank. Quality assurance of the content is provided by physician co-hosts who review episode scripts both prior to recording. Post-production feedback is elicited via comments on the curriculum's host website, CanadiEM.org, and through direct email correspondence to the ClerkCast address. Conclusion: With an ever increasing number of OERs in EM and critical care, the systematic development of new resources is important to avoid redundancies in content and medium while also addressing unmet learner needs. We describe the successful use of the Kern Six Steps for curriculum development for the creation of our novel EM OER for Canadian medical students, ‘ClerkCast’.
