Introduction: Current guidelines recommend patients with first trimester bleeding without previously documented intrauterine pregnancy undergo urgent transvaginal ultrasound (TVUS) to exclude ectopic pregnancy. However, in Canadian practice to receive urgent TVUS, particularly out of daytime hours is difficult, if not impossible. Thus, when TVUS is not available to exclude ectopic pregnancy, providers use point of care ultrasound (POCUS) or their best clinical judgment to determine if the patient can be safely discharged home while awaiting outpatient follow-up. The objective of this study was to determine what proportion of first trimester patients presenting to a community hospital emergency department (ED) with vaginal bleeding undergo either TVUS or POCUS to exclude ectopic pregnancy. Methods: This is an ongoing retrospective chart review of pregnant women gestational age (GA) less than 20 weeks presenting to a community hospital ED (103,000 visits/year) with a discharge diagnosis of vaginal bleed, first trimester bleed, threatened abortion, spontaneous abortion, missed abortion, rule out ectopic pregnancy, and ectopic pregnancy from January 2016 - January 2017. Patients are excluded if they are diagnosed with a ruptured ectopic pregnancy during their index ED visit. To date, 98 patient charts have been reviewed. Results: Of the 98 included patients, 13 (13.3%) had a viable pregnancy, 37 (37.8%) had a spontaneous or missed abortion, 4 (4.1%) had an ectopic pregnancy, and 45 (45.9%) had unknown outcomes. Of included patients, 4 (4.1%) only had POCUS, 66 (67.4%) only had a radiologist-interpreted TVUS, and 3 (3.1%) had both POCUS and radiologist-interpreted TVUS during their ED index visits. Thus, 73 (74.5%) had either a radiologist-interpreted TVUS or ED provider-performed POCUS during their index ED visit. After their index ED visits, 2 (2.0%) patients returned with ruptured ectopic pregnancies, 1 of whom had not undergone initial US investigations. Conclusion: Although TVUS is standard of care to exclude ectopic pregnancy in patients presenting with first trimester bleeding or abdominal pain, our preliminary results show some patients are not receiving this diagnostic modality nor POCUS during their index ED visit. Particularly in a setting, such as this ED, without rapid access to an early pregnancy clinic, patients should be counselled about their risk of ectopic pregnancy at the time of ED discharge.

Introduction: The field of Clinical Informatics (CI) and specifically the electronic health record, has been identified as a key facilitator to achieve a sustainable evidence-based healthcare system for the future. International graduate medical education programs have been challenged to ensure their trainees are provided with appropriate skills to deliver effective and efficient healthcare in an evolving environment. This study explored how international Emergency Medicine (EM) specialist training standards address training in relevant areas of CI. Methods: A list of categories of CI competencies relative to EM was developed following a thematic review of published references documenting CI curriculum and competencies. Publically available, published documents outlining core content, curriculum and competencies from international organizations responsible for specialty graduate medical education and/or credentialing in EM for the United States, Canada, Australasia, the United Kingdom and Europe. These EM training standards were reviewed to identify inclusion of topics related to the relevant categories of CI competencies. Results: A total of 23 EM curriculum documents were included in the thematic analysis. Curricula content related to critical appraisal/evidence based medicine, leadership, quality improvement and privacy/security were included in all EM curricula. The CI topics related to fundamental computer skills, computerized provider order entry and patient-centered informatics were only included in the EM curricula documents for the United States and were absent for each other organization. Conclusion: There is variation in the CI related content of the international EM specialty training standards which were reviewed. Given the increasing importance of CI in the future delivery of healthcare, organizations responsible for training and credentialing specialist emergency physicians must ensure their training standards incorporate relevant CI content, thus ensuring their trainees gain competence in essential aspects of CI.

Introduction: With the increasing volume of medical literature published each year, it is difficult for clinicians to translate the latest research into practice. Awareness is the first step of knowledge translation and journals have begun using social media to increase the dissemination and awareness of their publications. Infographics can describe research findings visually, are shared broadly on social media, and may be a more effective way to convey information. We hypothesized that infographic abstracts would increase the social media dissemination and online readership of research articles relative to traditional abstracts. Methods: In this randomized controlled trial, 24 original research articles were chosen from the six issues of the Canadian Journal of Emergency Medicine (CJEM) published between July 2016 and May 2017 (4 articles per issue). Half were randomized to the infographic and control groups within each issue. Infographic articles were promoted using a visual infographic outlining the findings of the article. Control articles were promoted using a screen capture image of each articles abstract. Both were disseminated through the journals social media accounts (Twitter and Facebook) along with the link to the selected article. Infographics were also published on CanadiEM.org. Abstract views, full text views, and the change in Altmetric score were tracked for 30 days and compared between groups. Unpaired two-tailed t-tests were used to detect significant differences. Results: Abstract views (mean, SD) were significantly higher for infographic articles (378.9, 162.0) than control articles (175.5, 69.2, p<0.001). Mean Altmetric scores were significantly higher for infographic articles (26.4, 13.8) than control articles (3.4, 1.7, p<0.0001). There was no statistically significant difference in full-text views between infographic (49.7, 90.4) and control articles (25.3, 12.3). Conclusion: CJEM articles promoted on social media using infographics had higher abstract viewership and Altmetric scores than those promoted with traditional abstracts. Although there was no difference in full-text readership, our results suggest that infographic abstracts may have a role in increasing the dissemination of medical literature.

Introduction: The management of patient flow in the emergency department (ED) is crucial for the practice of emergency medicine (EM). However, this skill is difficult to teach didactically and is learned implicitly in the latter half of residency training. To help expedite the learning process, we developed the GridlockED board game as an educational tool to simulate ED patient flow. By having junior medical trainees play this game, we believe that they will develop a greater understanding of patient flow and resource management in the ED. Additionally, since GridlockED is a cooperative game, players may also benefit by improving their communication and teamwork skills. Methods: GridlockED was developed over twenty months of iterative gameplay and review. Feedback from attending emergency physicians, residents, and medical students was integrated into the game through a Plan-Do-Study-Act (PDSA) model. Emergency medicine nurses, physicians and residents at McMaster University were recruited to play GridlockED. Each player completed a pre-survey to collect demographic data and to assess their prior experience with playing board games. All play sessions were recorded for data collection purposes. Following each game session, a member of the research team conducted an exit interview with the players to gather information about their play experience and the educational value of the game. A post-survey was also sent to each participant for further feedback. Results: Eighteen gameplay sessions were conducted from June to August 2017. A total of thirty-two participants played the game (13 emergency physicians, 15 residents, and four nurses). Overall responses to the post-gameplay survey showed that players endorsed GridlockED as a useful potential teaching tool (75%, n=24/32) and the majority felt that it had the potential to improve patient flow in the ED (56%, n=18/32). Most participants found that the game was easy to play (91%, n=27/29), and that the instructions were clear (87.5%, n=28/32). Respondents also felt that the game reflected real life scenarios (56%, n=18) and that cases reflected the types of patients that they saw in the ED (78%, n=25). Conclusion: Our results have shown an overall positive response to GridlockED, with most participants supporting it as both an engaging board game and potential teaching tool. We believe that future studies with larger sample sizes and medical students will further validate the use of serious games in medical education.

Introduction: The proliferation of unmanned aerial vehicle (UAV) technology has the potential to change the way medical incident commanders respond to mass casualty incidents (MCI) in triaging victims. The aim of this study was to compare UAV technology to standard practice (SP) in triaging casualties at a MCI Methods: A randomized comparison study was conducted with forty paramedic students from the Holland College Paramedicine Program. Using a simulated motor vehicle collision with moulaged casualties, iterations of twenty students were used for both a day and a night trial. Students were randomized to an UAV or a SP group. After a brief narrative participants either entered the study environment or used UAV technology where total time to triage completion, green casualty evacuation, time on scene, triage order and accuracy was recorded Results: A statistical difference in the time to completing of 3.63 minutes (95% CI: 2.45, 4.85, p=0.002) during the day iteration and a difference of 3.49 minutes (95% CI: 2.08,6.06, p=0.002) for the night trial with UAV groups was noted. There was no difference found in time to green casualty evacuation, time on scene or triage order. One hundred percent accuracy was noted between both groups. Conclusion: This study demonstrated the feasibility of using an UAV at a MCI. A non clinical significant difference was noted in total time to completion between both groups. There was no increase in time on scene by using the UAV while demonstrating the feasibility of remotely triaging green casualties prior to first responder arrival.

Introduction: Free Open Access Medical education (FOAM) resources have been developed using various needs assessment methods. We describe a storytelling exercise used to identify unperceived medical expert learning needs, which also resulted in the emergence of unknown learning needs within intrinsic physician roles. Methods: A FOAM curriculum was created for thrombosis based on an online needs assessment comprised of a topic listing, case scenarios, and a storytelling exercise. In the storytelling exercise, learners described i) a difficult case in thrombosis, and ii) why that case was difficult. In this qualitative description study, we performed a secondary thematic analysis of this storytelling data, coded for CanMEDS 2015 intrinsic roles. Two investigators independently coded transcripts to iteratively generate a coding framework. Results: 143 respondents completed the storytelling exercise. All responses yielded a gap in medical expertise, while 25 (17.5%) described an additional intrinsic theme. Learning needs in all six intrinsic roles were identified. The most commonly cited learning needs were in the Leader (recognizing how resource allocation impacts healthcare), Communicator (communicating expert knowledge with patients), and Collaborator (unclear communication between providers) domains. Participants who described an intrinsic learning need were primarily from emergency medicine (21/25, 84.0%). These excerpts were notable for how they expressed the complexity and affective components of medicine. Conclusion: Storytelling exercises can highlight context, attitudes, and relationships which provide depth to needs assessments. These narratives are a novel method of capturing emergent learning needs, which may be unknown to learner and faculty (Johari window). These intrinsic learning needs may ultimately be used to enrich learner-centered curricula.

Introduction: Choosing Wisely Canada has identified blood transfusions as a priority area for improving clinical appropriateness. Relevant recommendations include Dont transfuse blood if other non-transfusion therapies or observation would be just as effective. In parallel with this recommendation, the Alberta division of Towards Optimized Practice (ToP) has developed guidelines for the treatment of iron deficiency anemia (IDA) that emphasize the use of non-transfusion therapies (i.e. parenteral or oral iron, in appropriate patients). Choosing Wisely also emphasizes strategies to better engage patients in shared decision making. Methods: In order to better engage patients in shared decision making about their treatment options, both physician and patient handouts were developed using an iterative process. The development of the patient-facing documents began with a synthesis of educational materials currently available to patients with IDA. Clinical leaders from nine different specialties (Emergency Medicine, Family Medicine, Day Medicine, Hematology, and others) were continually engaged in the development of content using a consensus model. A focus group of ESCN patient advisors was assembled to review materials with an emphasis on: (1) Are the patient materials easily understood? (2) Are intended messages resonating while avoiding unintended messaging? (3) What information do patients require that has not been included? Following the focus group, revisions were made to patient materials and a subsequent online survey confirmed that the final version addressed any issues they had raised. Results: A four-page patient handout/infographic was developed utilizing best practices in information design, and in physician and patient engagement. Content includes the causes and symptoms of IDA, progressive treatment options from dietary changes to transfusion, and the four Choosing Wisely questions to discuss with your doctor. Conclusion: Patient education materials can be developed according to best practices in information design and stakeholder engagement. Patient focus groups demonstrate that such materials are easier to understand, and better equip patients to engage in shared decision making.

Introduction: Foreign patients often do not receive appropriate treatment in the emergency room as compared to locals. This is due to various causes such as language, insurance, and cultural differences. The purpose of this study was to investigate whether there is a wide range of health inequalities among foreigners who visited the emergency room with injury and to find out what causes it. Methods: We analyzed clinical data from the National Emergency Department Information System(NEDIS) database, which visited the emergency room from January 1, 2013 to December 31, 2015, in all age groups. Foreigners are classified based on the personal information described in the NEDIS. We analyzed the number of injuries, serious cases(death, operation, ICU admission), length of stay in ER, and transfer ratio. Results: A total of 4,464,603 cases of injured patients were included, of whom 67,683 were foreign patients. The incidence rate per 100,000 people per year was 2960.5 from locals and 1659.8 from foreigners. Serious outcomes were higher for foreigners than for locals(31.0% versus 23.2%, p<0.001). There was a further difference in the rural region. Length of stay was longer for foreigners(72 versus 69 minutes, median, p<0.001). The transfer rate was also higher for foreigners(1.9% versus 1.6%, p<0.001). Daegu had the highest ratio of foreigners’ injury compared to locals(ratio=0.998). Jeonnam(0.073) was the highest serious outcome rate in Korea, and Jeonbuk(0.070) was the second. The area with the longest length of stay in the Emergency department was the median 139 minutes for locals and 153 minutes for foreigners in Daegu. The more patients per day, the shorter the time spent in the emergency rooms(Spearman correlation coefficient=-0.388). This phenomenon was more prominent in locals(-0.624 versus -0.175). Multivariable logistic regression was used as a dependent variable for the serious outcomes of foreign patients. The foreign patients(OR=1.413, p<0.001), intention, no insurance, age, sex, urban area, low blood pressure, decreased consciousness, transfer, acuity, and length of stay were statistically significant. Conclusion: This study showed that there is a health inequality for foreigners who came to the emergency room due to injury in Korea. Also, serious outcomes from injury in foreigners have been shown to be related to various causes including factors of the foreigner.

Introduction: BACKGOUND In the modern era of terrorism and senseless violence, it is essential that hospital staff have expertise in implementation of a mass casualty incident (MCI) plan. OBJECTIVES 1. To assess current gaps in implementation of an academic urban hospital code orange plan using live simulation and tabletop exercise. 2. To identify and educate front-line staff to champion a hospital-wide MCI plan. INNOVATION Historically, in order to limit resource utilization and impact on patient care, disaster response training of front-line staff involved tabletop exercises only. The tenets of experiential learning suggest that learner engagement through realistic active practice of skills achieves deeper uptake of new knowledge. We enhanced the traditional tabletop approach through novel use of live actor patients presenting to an academic, urban emergency department (ED) during a hospital-wide MCI simulation. Methods: To assess the current code orange plan, an interprofessional, committee comprising expert leaders in trauma, emergency preparedness, emergency medicine and simulation integrated tabletop and live simulation to stage a MCI based on a mock incident at a new subway station. ED staff, the trauma team and champions from medicine, surgery and critical care participated along with support departments such as Patient Flow, Patient Transport, Environmental Services and the Hospital Emergency Operations Centre. Ten live actor patients and eight virtual patients presented to the ED. The exercise occurred in situ in the ED. Other participating departments conducted tabletop exercises and received live actor patients. Results: CURRICULUM Staff decanted the ED and other participating units using their current knowledge of hospital code orange policy. Live and virtual patients were triaged and managed according to severity of injuries. Live actor patients were assessed, intervened and transported to their designated unit. Virtual patients were managed through verbal discussion with the simulation controllers. An ED debrief took place using a plus/delta approach followed by a hospital-wide debrief. Conclusion: CONCLUSION An interprofessional hospital-wide MCI simulation revealed important challenges such as communication, command and control and patient-tracking . The exercise ignited enthusiasm and commitment to longitudinal practice and improvement for identified gaps.

Introduction: Final year emergency medicine residents may be transitioning to practice with little to no training on how to effectively supervise and assess trainees. It remains unclear how comfortable final year residents and new-to-practice physicians are with these competencies. The goal of our study was to examine physician comfort with supervision and assessment, whether there was a perceived need for formal training in these areas, and what gaps, barriers and enablers would exist in implementing it. Methods: Qualitative data were collected in two phases during September 2016-November 2017 through interviews of PGY5 emergency residents and new-to-practice staff at the University of Toronto and McMaster University in Ontario, Canada. A semi-structured interview guide was developed and used during the first round of interviews at the University of Toronto during phase one. Results from phase one were used to refine the interview guide, to be used in phase two, to ensure that all potential areas of thematic generation were touched upon. Phase two occurred at the University of Toronto and McMaster University using the refined interview guide. All transcripts were coded, analyzed, and collapsed into themes. Data analysis was guided by a constructivist grounded theory based in a relativist paradigm. Results: Thematic analysis revealed five themes. Residents and staff alike described acquiring the skills of supervision and assessment passively, primarily through modeling the behaviours of others; the training that is available in these areas is variably used, creating a diversity of physician comfort levels within these two competencies; the many competing priorities in the emergency department represent significant barriers to improving supervision and assessment; providing negative feedback is universally difficult and often avoided, sometimes resulting in struggling trainees not being identified until late in residency; the move towards competency based education (CBE) will act as an impetus for more formal curriculum being required in these areas. Conclusion: As residency programs transition to a CBE model, there will be a greater need for formal training in supervision and assessment to achieve a standard level of comfort and competence among senior residents physicians in independent practice. These competencies will also need an emphasis on how to identify struggling trainees, and how to approach negative and constructive feedback.

Introduction: Prior to opening Strathcona Community Hospital (STCH) site leadership were tasked to develop an innovative care model. The central aim was quality improvement and patient safety optimization in the emergency department (ED) utilizing a nurse practitioner (NP) model. They developed 3 pillars: collaboration, multidisciplinary approach, and integration with the plan of improving patient satisfaction and ensuring no patient gets lost to follow up. NPs work in the STCH ED and the NP led Emergency Department Transition (EDT) Clinic in Ambulatory Care. In the ED NPs provide direct clinical care, judicious review of DI and microbiology reports, and care coordination for patients at risk of lost to follow up. The EDT clinic is an innovative NP lead clinic with the purpose of providing timely, high-quality follow up care for ED patients. Methods: Data for the service delivery indicators came from data repository and manual data collection looking at the following outcomes: timely review of DI/micro results; decreased ED visits for non-urgent/emergent issues; safe transitions in care and improved patient satisfaction. Quantitative data from service delivery, patient and surveys were analyzed using Microsoft Excel and SPSS 19. Results: From June 2016 to January 2017 ED NPs at STCH reviewed 3000 positive microbiology reports and made 517 f/u calls to those patients, and reviewed 3181 DI results. This has freed up approximately 2 hrs per day of ED physician time. When NPs were working in the ED, the number of patients who left without treatment (LWT) was approximately 50% less, and improved STCH ED wait times to be among the lowest in the Edmonton Zone. From June 2016 to January 2017, EDT NPs completed 837 patient visits; 371 letters to family physicians (FPs); 215 referrals; and connected 520 patients to a new FP. Patient satisfaction survey show 88-90% of the patients were satisfied with their care. Conclusion: NPs are integral members of the ED team at STCH, providing direct clinical care and several valuable follow up services for ED patients. The EDT clinic provides urgent follow up for ED patients unable to get a timely appointment with their FP or no access to primary care. The clinic also prevents unnecessary returns to ED, and aids to bridge ED services to family physicians or specialist. NPs are the common thread through all departments at STCH, contributing to quality improvement and high patient satisfaction.

Introduction: Administrative data are attractive for research, policy and quality improvement initiatives as large amounts of data can often be obtained quickly and at low cost. Unfortunately, administrative data often have significant limitations owing to how they were collected and coded. In many cases, free text, often hand written, diagnoses provided by physicians are converted into ICD-10 (International Statistical Classification of Diseases and Related Health Problems, 10th Revision) codes by trained nosologists for administrative purposes. However, because of the large data sets often obtained from administrative sources, it is difficult to verify the accuracy of the data, which may lead researchers to misleading or false conclusions. The objective of this study was to evaluate the accuracy of ICD-10 codes for the diagnosis of pulmonary embolism (PE) in emergency department (ED) patients. Methods: As part of a larger study examining the effectiveness of a clinical decision support intervention on CT utilization and diagnostic yield for ED patients with suspected PE, all patients with an ICD-10 code corresponding to PE (126.0 and 126.9) on ED discharge were obtained from four adult urban EDs and one urgent care center from August 2016 to March 2017. PE diagnosis was confirmed by reviewing electronic medical records and imaging reports for all patients. Discrepancies between coded ICD-10 diagnoses and actual imaging findings were quantified. This study was REB approved. Results: Of 584 ED patients with ICD-10 codes identifying PE as a discharge diagnosis, 535 had imaging that could be reviewed. Of these, 225 (42.1%) did not have clinical diagnoses of PE, and thus were incorrectly coded, resulting in false positive ICD-10 codes. Common coding errors included physician free text diagnoses of rule out PE or query PE being coded as positive for PE. Conclusion: Administrative data are subject to errors in coding. In this study ICD-10 codes were not reliable for the diagnosis of PE, with 42.1% of PE diagnoses being false positives. Similar coding errors are likely for other diagnoses that require waits for confirmatory imaging (e.g. appendicitis). Nosologist coding of physician free text diagnoses is challenging and prone to errors. Consequently, validation of ICD-10 coding prior to analysis of administrative datasets is crucial for meaningful results.

Introduction: It is critical for planning, clinical care and resource optimization to understand patterns of emergency department (ED) utilization. Individuals who have experienced adverse childhood experiences (ACE) are known to have more unhealthy behaviors and worse health outcomes as adults and therefore may be more frequent ED users. Adverse childhood experiences include physical, sexual and emotional abuse or neglect, substance abuse in the family, witnessing violence, having a parent incarcerated or parents getting divorced or separated. To date there are few studies exploring the relationship between ACE and ED utilization. Methods: This a mixed qualitative and quantitative study. It includes analysis of data collected through a survey, a retrospective chart review and focus group discussions. The survey was administered to a convenience sample of adult patients (CTAS 2 -5) presenting to EDs in Kingston Ontario, and consisted of two validated tools that measured exposure to ACE and resiliency. Demographic data and ED utilization frequency for 12 months prior to the index visit were extracted from an electronic medical record for each patient completing the survey. A sample of participants with a high ACE burden (ACE score > 4) were invited to participate in focus groups to explore their experiences of care in the ED. Demographic, ED utilization and health status data were summarized and statistically significant patterns between high ACE and lower ACE patients were determined using Chi2t or t-tests. Transcripts from the focus groups were thematically analyzed using NVivo software by 2 independent researchers. Results: 1693 surveys were collected, 301 (18%) were deemed to have a high ACE score, data analysis is ongoing. The primary outcome is the relationship between ACE and the frequency of ED utilization among adult patients presenting to EDs in Kingston, ON. Secondary outcomes include evaluating the role of resilience as a potential mitigating factor, describing the demographics of high ACE burden frequent ED visitors, and the experiences of care for individuals with high ACE burden in the ED. These outcomes will be utilized to inform hypotheses for future studies and potential interventions aimed at optimizing ED utilization and patient care experience. Conclusion: This study provides novel insight into the relationship between ACE burden and ED utilization while also describing the demographics and experiences of care for ED patients with a high ACE score. Data analysis is on-going.

Introduction: Many patients with advanced or end-stage diseases spend months or years in need of optimal physical, spiritual, psychological, and social care. Despite efforts to provide community care, those with severe illness often present to emergency departments (EDs). This abstract presents preliminary results on the qualitative component of an ED-based mixed methods pilot study. The objective of this qualitative component is to develop and test an interview guide to collect qualitative data on physicians perceptions about unmet palliative care (PC) and end of life care (EOLC) needs in EDs. Methods: A scan of the literature on PC and EOLC in EDs was conducted to develop propositions about what might be expected through the clinician interviews, as well as an interview guide. The interview guide will be piloted with up to four ED physicians. During the interview each physician will describe a case where a PC patient had unmet care needs and the impacts they believe these unmet needs had on patients and families. Interview transcripts will be coded descriptively and then conceptually themed by the researcher who conducted the interview. Interpretations drawn from the interview data, with supporting quotations and comparison to initial propositions, will be presented to members of the research team with experience providing ED care, for further interpretation. Advice of a second trained qualitative researcher will be sought on the richness and relevance of data obtained and how the interview guide could be improved to elicit richer and/or more relevant data. A revised interview guide will be produced alongside rationales for why the proposed revisions will elicit richer data. Results: After reviewing 27 articles on PC and EOLC, propositions and an initial interview guide were developed based on themes from the literature and the study groups experiences. One of the primary results of this pilot work will be an enhanced understanding of PC and EOLC in our local ED context, as reflected in an interview guide revised to elicit richer data than achieved through the initial interview guide. Conclusion: The comparison between our propositions and the study findings will help identify how biases may have influenced interview questions and/or the interpretation of the data. This pilot work to develop an interview guide enhances the rigour of this qualitative work on unmet PC and EOLC needs in EDs.

Introduction: When a female presents with abdominal pain and vaginal bleeding, a positive b-hcg level helps in the diagnosis of an ectopic pregnancy. A timely diagnosis as well as management is required for these cases. In many emergency departments, there can be delays in laboratory processing of quantitative b-hcg levels as well as qualitative urine pregnancy tests. In others, especially in rural hospitals in Canada, the laboratory closes at night and these tests cannot be processed until the morning. This may also help decrease length of stay for some patients in the emergency department. There are currently new point-of-care b-hcg tests on the market using capillary blood, but these are expensive and not readily available. The purpose of the study is to validate the most inexpensive point of care urine pregnancy tests readily available on the market for use with capillary blood samples. These point-of-care tests have only been studied with urine and whole blood. If validated with capillary blood, it would allow for a very practical, rapid, and inexpensive test which could help doctors and nurses to triage patients in a timely and more efficient fashion. Methods: In our emergency department, 385 patients between the ages of 18-50 with possible pregnancy, abdominal pain or vaginal bleeding will be included in the study. A capillary blood sample will be taken and applied to a cassette point-of-care pregnancy test with four drops of saline. Two independent investigators will assess the test. The results will be compared to a quantitative serum hCG assay and urine. If these tests are not done as part of the patients medical care, the patient will be contacted one month after to enquire if the patient is pregnant or not. The sensitivity, specificity, positive and negative predictive values will be calculated. Results: Data colleciton will begin in January 2018. Conclusion: No conclusions can yet be drawn.

Introduction: Incentive spirometry (IS) is commonly used in post-operative patients for respiratory recovery. Literature suggest that it can possibly improve lung function and reduce post-operative pulmonary complication. There is no recommendation about the use of IS in the emergency department (ED). However, rib fractures, a common complaint, increase the risk of pulmonary complications. There is heterogeneous ED practice for the management of rib fractures. The objective of this study is to assess the benefits of IS to reduce potential delayed complications in ED discharged patients with confirmed rib fracture. Methods: This is a prospective observational planned sub-study in 4 canadians ED between November 2006 and May 2012. Non-admitted patients over 16 y.o. with a main complaint of minor thoracic injury and at least one suspected/confirmed rib fracture on radiographs were included. Discharge recommendations of IS use was left to attending physician. IS training was done by ED nurses. Main outcomes were pneumonia, atelectasis and hemothorax within 14 days. Analyses were made with propensity score matching. Results: 450 patients with at least one rib fracture were included. Of these, 182 (40%) received IS with a mean age of 57.0 y.o. Patients with IS seem to have worse condition. 61 (33.5%) had 3 fractures comparatively to 56 (20.9) for patient without IS. Although, the groups were similar for mean age, sex and mechanism of injury. There were in total 76 cases of delayed hemothorax (16.9%), 69 cases of atelectasis (15.3%) and five cases of pneumonia (1.1%). The use of IS was not protector for delayed hemothorax (RR= 0.80, 95% CI [0.45 1.36]) and nor for atelectasis or pneumonia (RR=0.74, 95% CI [0.45 1.36]) Conclusion: Our results suggest that unsupervised and broad incentive spirometry use does not seem to add a protective effect against the development of delayed pulmonary complications after a rib fracture. Further study should be made to assess the usefulness of IS in specific injured population in the ED.

Introduction: Upper gastrointestinal bleeding (UGIB) is a common medical condition presenting to emergency departments (ED) and associated with substantial morbidity, mortality, and healthcare expenditures. Our aim was to evaluate the incidence of patients presenting to ED with UGIB in a large population-based surveillance cohort. Methods: The National Ambulatory Care Reporting System (NACRS) was used to identify all presentations to emergency departments for UGIB in Alberta from fiscal year 2010 to 2015 (n=56519) using the International Classification of Diseases Codes (ICD-10) in any diagnostic position. Baseline characteristics and UGIB incidence were calculated using descriptive statistics. Joinpoint regression models were used to calculate the average annual percent change (AAPC) with 95% confidence intervals (CI). Results: The median age of 56519 UGIB presentations was 56 years (interquartile range: 41 to 74 years), 56% were male, and 245% had at least one comorbidity. At time of disposition from the ED , 48.3% were admitted to or transferred to another hospital, 51.4% discharged, and 0.3% died in the emergency department. Further, 10.8% underwent upper endoscopy during their admission to the emergency department. The annual incidence of UGIB were 230.6 (2010), 232.8 (2011), 241.0 (2012), 242.2 (2013), 244.6 (2014), and 242.2 (2015) per 100,000 person-years. Between 2010 and 2015 the incidence of UGIB presenting to ED significantly increased overtime (AAPC=1.1; 95% CI: 0.3 to 2.0). Conclusion: UGIB is a common presentation to emergency departments and has been increasing overtime. Future studies are necessary to evaluate the underlying cause of UGIB and to determine its burden to Albertas healthcare system.

Introduction: Emergency department (ED) physicians strive to provide analgesia, amnesia and sedation for patients when performing painful procedures through the use of procedural sedation (PS). Examination of the literature suggests that the application of PS appears to be variable with institutional influences and clinician disagreement on pharmacology, airway management, and monitoring. The primary goal of this research project was to describe the variability of practice with respect to pharmacologic choices and clinical applications of PS among Canadian ED physicians. Methods: An electronic survey was distributed through the Canadian Association of Emergency Physicians (CAEP). Practicing physician members of CAEP were invited to complete the survey. The 20 question survey encompassed various aspects of PS including physician choices regarding PS indications and pharmacology. The primary outcome was the quantification of practice variability among ED physicians with respect to the above listed aspects of PS. The data was presented with simple descriptive statistics. Results: To date, 278 ED physicians responded to our survey (response rate 20.3%). Respondents were primarily academic hospital (53.2%) or community hospital based (38.2%). With emergency medicine training as: CCFP-EM (55.2%), FRCPC (30.1%), and CCFP (9.0%). There was relative agreement on the following interventions requiring PS: 98.4% applied PS for electrical cardioversion and 98.1% for brief (<10 mins) orthopedic manipulations. However, only 36.3% utilized PS for burn debridement in the ED. PS was utilized less frequently (78.1%) for prolonged (>10mins) orthopedic manipulations than brief manipulations. For all procedures aggregated, in hemodynamically stable patients with an American Society of Anesthesiology (ASA) score of 1, ED physicians utilized propofol 76.3% of the time. Additional agents were utilized at the following rates: fentanyl-propofol (7.6%), ketamine (7.6%), and fentanyl (4%). This inclination towards propofol alone appears to be consistent across modality of ER training, type of ER setting (rural vs academic), and volume of PS performed. Conclusion: This study demonstrates that Canadian ED physicians have a clear preference for propofol as a first line pharmacologic agent when administering PS in hemodynamically stable, ASA1 patients. Conversely, there appears to be more variation amongst ED physicians with respect to second line pharmaceutical choices for PS.

Introduction: Emergency department (ED) physicians strive to provide analgesia, amnesia and sedation for patients undergoing painful procedures through the use of procedural sedation (PS). While, PS is generally safe and effective in the ED, there is institutional variability and clinician disagreement with respect to the bedside equipment required for airway management and the monitoring of adverse events. The primary goal of this research project was to describe the variability of the bedside setup utilized by Canadian ED physicians preforming PS in conjunction with self-reported adverse events. Methods: An electronic survey was distributed through the Canadian Association of Emergency Physicians (CAEP). Practicing physician members of CAEP were invited to complete the survey. The 20 question survey encompassed various aspects of PS including physician choices regarding bedside setup of airway equipment, and prevalence of self-reported adverse events. The primary outcome was the quantification of variability among ED physicians with respect to the above listed aspects of PS. Data was presented with simple descriptive statistics. Results: 278 ED physicians responded to our survey (response rate 20.9%). Respondents were primarily academic (53.2%) or community hospital based (38.2%). With emergency medicine training as: CCFP-EM (55.2%), FRCPC (30.1%), and CCFP (9.0%). The ED area in which PS was carried out varied; bedside (30.5%), procedure room (37.1%), resuscitation area (31.2%). The basic equipment set utilized appears to be a bag valve mask, suction, and an oral airway. These 3 items were present 95.4%, 95.9%, and 86.3% of the time respectively. The preparation of other items such as capnography and difficult airway equipment is highly variable and appears to be physician specific rather than clinical situation specific. The most common physician self-reported adverse events associated with PS appear to be hypoxia (Spo2<90%), hypotension (sBP<90), and prolonged sedation which occurred in 10.7%, 8.3%, and 8.1% of PS performed. Conclusion: There appears to be significant practice variability with respect to the clinical setting as well as the equipment ED physicians prefer when administering PS. Given that causal relationships cannot be inferred between airway/monitoring equipment preferences and adverse events, future studies should be targeted at identifying optimal bedside set ups which minimize adverse events.

Introduction: The cricothyroid membrane is used as a landmark for emergent surgical airway access. Ultrasound identification of the cricothyroid membrane is more accurate than landmarking by palpation. The objective of this study was to determine whether head of bed elevation affects the position of the cricothyroid membrane as identified by ultrasound. Methods: This was a prospective, observational study on a convenience sample of adult patients presenting to the emergency department. Participants underwent ultrasound scans by trained physicians at 0, 30 and 90 degrees head of bed elevation to identify the cricothyroid membrane. The cricothyroid membrane position identified at 0 degrees was used as a reference, and the change in position of the external landmark of the cricothyroid membrane with the patient at 30 and 90 degrees was measured. Additionally, the patients gender, age, body mass index (BMI) and Mallampati score were recorded for comparison. Linear mixed effects models with 95% confidence intervals were used to determine the effect of head of bed elevation, age, BMI and Mallampati score on the differences between measured distances. Results: One hundred and two patients were enrolled in the study. The average change in position from reference was statistically significant for both 30 degrees [2.72±0.77mm (p<0.01)] and 90 degrees [4.23±0.77mm (p<0.01)] head of bed elevation. The adjusted linear mixed effects model showed age greater than 70, BMI over 30 and higher Mallampati score were associated with greater change in distance between cricothyroid membrane landmarks. Conclusion: There was a statistically significant difference in the position of the cricothyroid membrane comparing 0 degrees to 30 and 90 degrees head of bed elevation. However, the relatively small differences suggest that this finding is not clinically relevant. Further study is required to evaluate if these differences impact the actual successful performance of cricothyrotomy.
