Introduction: For patients with chest pain, the target time from first medical contact to obtaining an electrocardiogram (ECG) is 10 minutes, as reperfusion within 120 minutes can reduce the risk of death and adverse outcomes in patients with ST elevation myocardial infarction (STEMI). In 2007, Vancouver Coastal Health (VCH) began tracking key indicators including time to first ECG. The Vancouver General Hospital (VGH) Emergency Department (ED) has been troubled with the longest door to ECG times in the region since 2014. In 2016, the VGH ED Quality Council developed a strategy to address this issue, with an aim of obtaining ECGs on 95% of patients presenting to the VGH ED with active chest pain within 10 minutes of presentation within a 6 month period. Methods: The VGH ED Quality Council brought together frontline clinicians, ECG technicians, and other stakeholders and completed a process map. We obtained baseline data regarding the median time to ECG in both patients with STEMI and all patients presenting with chest pain. Root cause analysis determined two main barriers: access to designated space to obtain ECGs, and the need for patients to be registered in the computer system before an ECG could be ordered. The team identified strategies to eliminate these barriers, identifying a dedicated space and undergoing multiple PDSA cycles to change the workflow to stream patients to this space before registration. Results: Our median times in patients with STEMI have gone from 33 minutes to 8 minutes as of June 2017. In all patients presenting with chest pain, we improved from a median of 36 to 17 minutes. As of April 2017 we are obtaining an ECG within 10 minutes in 27% of our patients, compared to 3% in 2016. Given the limitations in our data extraction process, we were not able to differentiate between patients with active chest pain versus those whose chest pain had resolved. Conclusion: By involving frontline staff, and having frontline champions providing real time support, we were able to make significant changes to the culture at triage. We cultivated sustainability by changing the workflow and physical space, and not relying on education only. While we have improved the times for our walk-in patients, we have not perfected the process when a patient moves immediately to a bed or presents via ambulance. Implementing small changes and incorporating feedback has allowed us to identify these new challenges early.

Introduction: Physician Initial Assessment (PIA) time at the Montfort Emergency Department (ED) in Ottawa is one of the longest in the province. PIA, Length of Stay (LOS), and Left Without Being Seen (LWBS) are all performance measures which impact hospital funding through the pay for results (P4R) system. Increased PIA times negatively impact hospital funding, patient satisfaction and may be correlated to patient safety. Our aim was to examine whether having a physician at triage during the last hour of their shift decreased PIA time, LOS, and LWBS rate, and also to overall improve patient care received in the Emergency Department. Methods: During the last hour of five different Emergency Department (ED) shifts (14-15h, 16-17h, 19-20h, 22-23h, 23h-00h), the physician worked with a designated registered nurse, evaluating patients in a room adjacent to triage and the waiting room. The current study evaluated the effectiveness of having a physician perform initial assessments at triage (including history, physical and ECG) and assess the impact on PIA time, LOS, and LWBS during the specific hours that a physician is at triage. This is a pre-post retrospective study. Baseline data was collected retrospectively over a period of 20 weeks prior to the intervention (between January 2017 and June 2017). Intervention data was collected over a period of 20 weeks starting in June 2017. Statistical process control (SPC) methodologies were then applied to the pre-post data of continuous variables. PIA time and LOS averages were obtained for each hour in which the physician was stationed at triage. I (XmR) charts were used for statistical analysis. Analysis was done using QI macros in Microsoft Excel. Results: Reductions in PIA times of 8 minutes (14-15h), 16 minutes (16-17h), 30 minutes (19-20h), 72 minutes (22-23h) and 88 minutes (23h-00h) were demonstrated across the 5 shifts throughout the trial period. No clear increase in LWBS wait times were demonstrated. Overall ED volumes increased modestly over the course of the intervention. Overall ED LOS in the department decreased about 25 minutes over this same period. There were no other PIA or LOS reduction initiatives taking place in the ED over the trial period. Conclusion: The goal of this study was to have patients seen quickly by an emergency physician at triage who would perform a rapid initial assessment and respond to needs for pain management, and order urgent testing or imaging. In this study, PIA times improved after the process change for every time period tested. One possible limitation was that this intervention likely had less adherence at the beginning of the trial as the staff adjusted to the new shift flow. This seems to be reflected in the data, since an improved process change is demonstrated near the end of the trial period. The next step in quality care improvement is to look at lab and imaging data to evaluate the utilization of tests with a physician at triage.

Introduction: The 2015 CanMEDS framework requires all residency programs to increase their focus on Quality Improvement and Patient Safety (QIPS). We created a longitudinal (4-year), modular QIPS curriculum for FRCP emergency medicine residents at the University of Toronto (UT) using multiple educational methods. The curriculum addresses three levels of QIPS training: knowledge, practical skills at the microsystem level, and practical skills at the organization level. Aim Statement: To increase the UT FRCP emergency medicine residents absolute score on the QIKAT-R (Quality Improvement Knowledge Application Tool Revised) by 10% after the completion of the QIPS curriculum. Methods: Physicians and other healthcare professionals with QI expertise collaboratively designed and taught the curriculum. We used the QIKAT-R as the outcome measure to evaluate QI knowledge and its applicability. The QIKAT-R is a validated measure that assesses an individuals ability to decipher a QI issue within the healthcare context, and propose a change initiative to address it. The first cohort of residents completed the QIKAT-R prior to the first session in 2014 (pre) and at the completion of the curriculum in 2017 (post). Each response was anonymized and scored by physicians with QI expertise. The QIKAT-R scores and comments from course evaluations are used to make yearly iterative curriculum changes. Results: The QIPS curriculum was implemented in September 2014. All nine residents in the first cohort completed the curriculum; they demonstrated an absolute increase of 19.6% (5.3/27) in the mean QIKAT-R score (13.0 +/− 3.3 pre vs. 18.3 +/− 3.8 post, p=0.001). Of the pre-test responses, 26% were categorized as poor, 70% as good, and 4% as excellent, whereas of the post-test 11% of responses were categorized as poor, 37% as good, and 52% as excellent (p<0.001). Two iterative curriculum changes were made at the end of each academic year since 2014: (1) The time between sessions were decreased to promote knowledge retention, and (2) different PGY3 QI practical project options were provided to suit residents individual QI interests. QIKAT-R scores and resident feedback were used to evaluate the impact of the curriculum changes. Conclusion: A collaborative, modular, longitudinal QIPS curriculum for UT FRCP emergency medicine residents that met CanMEDS requirements was created using multiple educational methods. The first resident cohort that completed the curriculum demonstrated an absolute increase in QI knowledge and its applicability (as measured by the QIKAT-R) by 19.6%. Two PDSA cycles were completed to improve the curriculum with the change ideas generated from resident feedback. Ongoing challenges include limited staff availability to teach and supervise resident QI projects. Future directions include incentivising staff participation and providing mentorship for residents with a career interest in QI beyond what is offered by the curriculum.

Introduction: The administration of “to-go” medications in the Kelowna General Hospital Emergency Department was identified as an issue. Frequently, multiple administrations of “to-go” medication pre-packs were administered to individual patients on a frequent basis. In addition, the variability in “to-go” medication was substantial between providers. Recognizing the patient issues (addiction, dependency and diversion) and system issues (costs, risk) a team-based quality improvement initiative was instituted, utilizing a variety of quality improvement techniques. The aim was to reduce the number of “to-go” medications by half, within a year. Methods: The project began January 2015, and is ongoing. Multiple stakeholders were engaged within the emergency department; these included leaders of the physician, nursing and pharmacy teams, including an executive sponsor. Using change theory, and traditional Plan-Do-Study-Act (PDSA) cycles, an iterative methodology was proposed. The outcome measure proposed was number of “to-go” medications administered; secondary measures included number of opioid “to-go” and benzodiazepine “to-go“prescriptions. Balancing measures were the number of narcotic prescriptions written. Physician prescribing practice and nursing practice were reviewed at meetings and huddles. Individualized reports were provided to physicians for self-review. Data was collated at baseline then reviewed quarterly at meetings and huddles. Run charts were utilized along with raw data and individualized reports. Results: At baseline (January 2015), the number of “to-go” medications was 708. Over the next year, this value reduced to 459, showing a 35% reduction in “to-go”. Two years later (June 2017), this had reduced to 142, resulting in an overall reduction of 80% “to-go” medications. Secondary measures are currently under analysis. Further, no increase in prescribing of narcotics was seen during this time period. Conclusion: The administration of “to-go” medications from the emergency department has significant individual and societal impact. Frequently, these medications are diverted; meaning, sold for profit on the black market. Further, opioid prescribing is under increased scrutiny as the linkage between opioid prescriptions and addiction / dependency becomes more evident. This quality improvement initiative was successful for a number of reasons. First, we had strong engagement from the full emergency department clinical teams. The issue was first identified collaboratively, and teamwork and participation was strong from the outset. Second, we used individual and aggregate data to provide feedback on a regular basis. Third, we had strong support from our executive sponsor(s) who were able to support the efforts and champion and present the results locally, and now, throughout the Health Region.

Introduction: Patients in our ED were dissatisfied with their waiting experience, which resulted in patient anxiety and complaints. In 8 months, we aimed to (1) improve patient satisfaction with the ED waiting experience from triage to physician initial assessment by a 15% improvement in patients who rate their experience very good/excellent on a Likert Scale, and (2) improve patient knowledge of ED wait time by a 50% increase in understanding on a Likert Scale. Methods: We co-designed a display with ED patients to notify those in the waiting room of their wait process and wait time. The intervention was selected after root cause diagnostics including: Fishbone exercise, Pareto Diagram, and Driver Diagram. The display was co-designed with ED patients and improved via PDSA cycles to establish information displayed and how to incorporate it into the waiting experience. After co-design, a low-fidelity display was piloted in the waiting room. Results: A family of measures were evaluated using patient/provider surveys and hospital data metrics. Outcome measures were (1) percentage of patients who rated their ED experience as very good/excellent on a Likert scale, and (2) patients who had a clear/very clear understanding of their wait time on a Likert scale. Process measures were the percentage of patients who (1) looked at the wait time display, and (2) felt they could communicate their wait time to others. Balancing measures were clerk/nurse satisfaction and self-reported interruptions of patients asking wait time. Outcomes were tracked using statistical process charts and run charts. Following display implementation, patient rating of their ED experience and patient understanding of wait time showed positive improvement. Clerks/nurses were also more satisfied with their jobs and self-reported interruptions decreased. Conclusion: A low-fidelity wait time display co-designed with patients improved patient satisfaction and understanding of ED wait times. We plan to develop an automated electronic display that resembles the low-fidelity display and evaluate the impact of the intervention on the established measures. This intervention has the potential to be sustainable, feasible for other EDs, and require minimal upkeep costs.

Introduction: The effectiveness of intravenous alteplase is highly time dependent, and very short door-to-needle times (DNT) of 30 minutes or less have been reported in single centre hospitals, but never in an entire population. QuICR (Quality Improvement and Clinical Research) Alberta Stroke Program aimed to reduce DNT to a median of 30 minutes across the Canadian province of Alberta. Methods: We used the Improvement Collaborative Methodology from early 2015 to September 2016 with participation from all 17 Stroke Centres in Alberta. This methodology included 4 face-to-face workshops, site visits, webinars, data collection, data feedback, intensive process mapping, and process improvements. We compared data in the pre-intervention period from 2009-2014 (collected during the Alberta Provincial Stroke Strategy) to data in the post-intervention period from March 2016-February 2017 (collected during the QuICR DTN Collaborative). Data from January 2015-February 2016 were excluded, as improvements were being implemented during this time. Results: There were a total of 2,322 treated cases in the pre- and post-intervention periods. The results show that the median DNT dropped from 68 minutes (n=1846) in the pre-intervention period to 36 minutes (n=476) in the post-intervention period (p<0.001). There were reductions in DNT across all hospital types: median DNT dropped from 63 to 32 minutes in Urban Tertiary Centres (p<0.001), from 73 to 32 minutes in Community with 24/7 neurology (p<0.001), from 85 to 62 minutes in Community with limited/no neurology (p<0.001), and from 74 to 52.5 minutes in rural centres (p<0.001). Conclusion: There were 21.5 to 41 minute reductions in median DNT across all hospital types including smaller rural and community hospitals. A targeted multi-site improvement collaborative can be an effective intervention to reduce DNT across an entire population.

Introduction: Patients with acute atrial fibrillation or flutter (AAFF) are the most common acute arrhythmia cases requiring care in the ED. Our goal was to adapt the existing Canadian Cardiovascular Society (CCS) AF Management Guidelines into an emergency physician-friendly best practices checklist. Methods: We chose to adapt, for use by emergency physicians, existing high-quality clinical practice guidelines (CPG) previously developed by the CCS using the GRADE system. We used the Canadian CAN-IMPLEMENT© process adapted from the ADAPTE Collaboration. We created an Advisory Committee consisting of 14 academic and community emergency physicians, three cardiologists, one PhD methodologist, and two patients. The Advisory Committee communicated by a two-day face-to-face meeting, teleconferences, and email. The checklist was prepared and revised through a process of feedback and discussions through ten iterations until consensus was achieved. We then circulated the draft checklist for comment to approximately 300 emergency medicine and cardiology colleagues whose written feedback was further incorporated into the final approved version. Results: The final CAEP ED AAFF Guidelines are comprised of two algorithms and four sets of checklists, organized by 1) Assessment and Risk Stratification, 2) Rhythm and Rate Control, 3) Long-term Stroke Prevention with the CHADS-65 Algorithm, and 4) Disposition and Follow-up. The guidelines have been endorsed by CAEP and accepted for publication in the Canadian Journal of Emergency Medicine. During the consensus and feedback processes, we addressed a number of issues and concerns. We highlighted the issue that many unstable patients are actually suffering from underlying medical problems rather than a primary arrhythmia. One controversial recommendation is to consider rate control or transesophageal echocardiography guided cardioversion if the duration of symptoms is 24-48 hours and the patient has two or more CHADS-65 criteria. We emphasize the importance of evaluating long-term stroke risk by use of the CHADS-65 algorithm and encourage ED physicians to prescribe anticoagulants where indicated. Conclusion: We have created the CAEP AAFF Best Practices Checklist which we hope will standardize and improve care of AAFF patients in all EDs across Canada. We believe that most of these patients can be managed rapidly and safely with ED rhythm control, early discharge, and appropriate use of anticoagulants.

Introduction: Les patients souffrant dun arrêt cardiaque extra hospitalier (ACEH) sont fréquemment traités à laide de soins avancés en réanimation cardiovasculaire (SARC). Dans ce contexte, des bicarbonates de sodium sont parfois administrés à des patients en arrêt cardiaque réfractaire chez qui une acidose métabolique importante, une hyperkaliémie ou une intoxication est suspectée. Puisquil ny a que peu dévidences quant à cet usage, lobjectif de la présente étude est dévaluer lassociation entre le traitement à laide de bicarbonate de sodium (une dose ou plus) et le devenir (retour de circulation spontané et survie au congé) chez les patients souffrant dun ACEH. Methods: La présente étude de cohorte a été réalisée à partir des bases de données de la Corporation dUrgences-santé dans la région de Montréal entre 2010 et 2015. Les patients adultes ayant souffert dun ACEH dorigine médicale traités en préhospitalier par des paramédics de soins avancés prodiguant des SARC ont été inclus. Les associations dintérêt ont été évaluées initialement à laide de régressions logistiques univariées, puis à laide de régressions logistiques multivariées ajustant pour les variables sociodémographiques et cliniques pertinentes. Results: Un total de 1973 patients (1349 hommes et 683 femmes) dun âge moyen de 66 ans (±17) ont été inclus dans cette étude, parmi lesquels 77 (3,8%) ont reçu une dose de bicarbonate, 763 (37,5%) ont retrouvés un pouls en préhospitalier et 222 (10,9%) ont survécu jusquà leur congé de lhôpital. Sans ajustement, il y avait une association négative entre le traitement à laide de bicarbonates et le retour de circulation spontané (rapport de cotes [RC]=0,46 [intervalle de confiance {IC} 95% 0,27-0,79], p=0,005) et la survie au congé (RC=0,21 [IC 95% 0,05-0,86], p=0,030). Cependant, ces associations nétaient plus significatives suite à lajustement pour les autres covariables (RC ajusté=0,63 [IC 95% 0,34-1,18], p=0,15 et RC ajusté=1,69 [95% IC 0,29-10,01], p=0,56). Conclusion: Il ny a pas dassociation indépendante entre le traitement à laide de bicarbonates et le devenir chez les patients souffrant dun ACEH. Dans ce contexte, il serait adéquat de réaliser un essai clinique afin de trancher définitivement sur cette question.

Introduction: Emergency health care providers (HCPs) regularly perform difficult medical resuscitations that require complex decision making and action. Critical incident debriefing has been proposed as a mechanism to mitigate the psychological effect of these stressful events and improve both provider and patient outcomes. The purpose of this updated systematic review is to determine if HCPs performing debriefing after critical incidents, compared to no debriefing, improves the outcomes of the HCPs or patients. Methods: We performed a librarian assisted systematic review of OVID Medline, CINAHL, OVID Embase and Google Scholar (January 2006 to February 2017) No restrictions for language were imposed. Two investigators evaluated articles independently for inclusion criteria, quality and data collection. Agreement was measured using the Kappa statistic and quality of the articles were assessed using the Downs and Black evaluation tool. Results: Among the 658 publications identified 16 met inclusion criteria. Participants included physicians, nurses, allied health and learners involved in both adult and pediatric resuscitations. Findings suggest that HCPs view debriefing positively (n=7). One moderate quality study showed that debriefing can enhance medical student and resident knowledge. Several studies (n=8) demonstrated at least some improvement in CPR and intubation related technical skills. Debriefing is also associated with improved short term patient survival but not survival to discharge (n=5). Two studies reported benefits to HCPs mental health as evidenced by improved ability to manage grief and decreased reported symptoms of Post-Traumatic Stress Disorder (PTSD). Conclusion: We found HCPs value debriefing after critical incidents and that debriefing is associated with improved HCP knowledge, skill and well-being. Despite these positive findings, there continues to be limited evidence that debriefing significantly impacts long term patient outcomes. Larger scale higher quality studies are required to further delineate the effect of structured debriefing on patient and provider outcomes.

Introduction: Long-term outcomes following out-of-hospital cardiac arrest (OHCA) remain poor. Two-thirds of OHCA patients surviving to hospital admission die from neurological injuries, and of those discharged, one-third have irreversible cognitive disabilities due to cerebral ischemia. Near-infrared spectroscopy (NIRS) is a non-invasive imaging technique which is able to continuously detect regional cerebral oxygenation (rSO2). NIRS monitoring has been used to measure rSO2 during in-hospital cardiac arrest resuscitation. Our study is the first feasibility study of paramedics applying NIRS monitoring during OHCA resuscitation. Methods: One NIRS monitor (Equanox 7600; Nonin, Plymouth, MI, USA) was placed on an Emergency Response Unit (ERU) with York Region Paramedic Services. ERU paramedics were trained to apply the device to patients foreheads during OHCA resuscitation and record rSO2 until arrival at hospital or termination of resuscitation. Paramedics did not alter any aspect of patient care by using the NIRS monitor. They were instructed to press an action marker on the device during ACLS interventions (e.g. defibrillation, intubation, medications, etc). rSO2 data was later downloaded for analysis. Our feasibility criteria was to obtain >70% of data files with rSO2 data and >70% of data files with event markers. Results: Data was collected from 24 OHCA patients over a period of 10 months. 19 cases (79%) files contained rSO2 data and 17 cases (71%) had event markers. The rSO2 data present in each file varied widely from complete recording for the entire call duration to sporadic brief readings. Event markers varied from 1 to 10 markers spaced throughout the cases. Conclusion: This is the first study to demonstrate that the use of NIRS by paramedics as part of OHCA resuscitation is feasible. Future studies are required to determine how rSO2 monitoring can be used to guide OHCA resuscitation. The results of this study will help inform protocols for future studies evaluating the use of NIRS in the out-of-hospital setting.

Introduction: Recent reports suggest that up to 30% of medical interventions provide no benefit to patients. In a response to ED over-crowding, guidelines commonly exist to guide blood test ordering in patients waiting to see a physician. In many cases, this increases the use of tests without benefiting patients. We describe a quality improvement project designed to reduce the number of laboratory tests considered routine for waiting patients. Methods: A multidisciplinary group reviewed existing symptom-prompted nursing blood test guidelines for serum electrolytes and glucose, renal function tests, liver tests, lipase, toxicological tests and beta Human Chorionic gonadotrophin levels. Order sets were revised with tests eliminated from the routine panels that were not felt to routinely contribute to patient care. The new guidelines were communicated to nursing staff in a series of educational sessions, and the revised guidelines were posted at nursing stations. Physician ordering practice was not changed. A pre-post evaluation compared the period 1 December 2014, - 30 November 2015 with 1 December 2015 - 30 November 2016. Clinical outcomes and patient wait times were not evaluated. Results: The use of tests in these categories decreased 32% between the two periods, at a net saving of $210, 246c. The largest savings came from total protein (73% decrease), Creatine kinase (68%), chloride (64%), glucose (49%), and albumin (47%). Sodium/Potassium testing decreased by only 13%. The only increase in test ordering recorded was AST (3% increase). Conclusion: Simply changing symptom driven order sets resulted in significant savings to the system. In the era of Choosing wisely regular review of lab order sets is indicated. Further study is needed to assess the effect of these changes on patient flow and on clinical outcome.

Introduction: In many rural and remote communities in BC, family physicians who are providing excellent primary and emergency care would like to access useful, timely, and collegial support to ensure the highest quality of health services for their patients. We undertook a real-time virtual support project in Robson Valley, located in northern BC, to evaluate the use of digital technologies such as videoconferencing for on demand consultation between family physicians at rural sites and emergency physicians at a regional site. Telehealth consults also occurred between rural sites with nurses at community emergency rooms consulting with local on-call physicians. Our aim was to use telehealth to facilitate timely access to high quality, comprehensive, coordinated team-based care. An evaluation framework, based on the Triple Aim sought to: 1) Identify telehealth use cases and assess impact on patient outcomes, patient and health professional experience, and cost of health care delivery; and 2) Assess the role of relationships among care team members in progressing from uptake to normalization of telehealth into routine usage. Methods: Using a participatory approach, all members of the pilot project were involved in shaping the pilot including the co-development of the evaluation itself. Evaluation was used iteratively throughout implementation for ongoing quality improvement via regular team meetings, sharing and reflecting on findings, and adjusting processes as required. Mixed methods were used including: interviews with family physicians, nurses, and patients at rural sites, and emergency physicians at regional site; review of records such as technology use statistics; and stakeholder focus groups. Results: From November 2016 to July 2017, 26 cases of telehealth use were captured and evaluated. Findings indicate that telehealth has positively impacted care team, patients, and health system. Benefits for care team at the rural sites included confidence in diagnoses through timely access to advice and support, while emergency physicians at the regional site gained deeper understanding of the practice settings of rural colleagues. Nevertheless, telehealth has complicated the emergency department work flow and increased physician workload. Findings demonstrated efficiencies for the health system, including reducing the need for patient transfer. Patients expressed confidence in the physicians and telehealth system; by receiving care closer to home, they experienced personal cost savings. Implementation saw a move away from scheduled telehealth visits to real use of technology for timely access. Conclusion: Evidence of the benefits of telehealth in emergency settings is needed to support stakeholder engagement to address issues of workflow and capacity. This pilot has early indications of significant local impact and will inform the expansion of emergency telehealth in all emergency settings in BC.

Introduction: Intravenous (IV) therapy in the emergency department (ED) is associated with risk of harm from IV complications, higher ED monitoring requirements and increased ED length of stay (LOS), the latter a measure most cumbersome in lower-acuity patients that are eventually discharged from the ED. The aim of this quality improvement project was to evaluate the effectiveness of educational and audit-and-feedback interventions, with a goal of relative reduction of ED IV therapy by 20% over eight week periods, in lower-acuity patients in the high-turnover intake area of the ED who were discharged from the ED. Methods: The first cycle of the project was education about IV therapy use and alternatives in lower-acuity, ED patients (Canadian Triage Acuity Scale (CTAS) 3 and 4) from July 2 to August 31, 2017. Education was delivered through email information, posters, education sessions with nurse educators, and working groups sharing information. The second cycle of the project, from October 16 to December 15, 2017, also integrated an audit-and-feedback tool whereby physicians received their own pooled ordering data of IVs from the same period the previous year and then trial period as well pooled comparison averages for the physician group in the population of interest. Measures were the percentage of IVs ordered by physicians and administered by nurses in the population of interest in each time period. Results: From July 2 to August 31, 2017, when the intervention was education only, the rate of IV therapy changed from 31% to 37%, which reflects a 19% relative increase in IV use. In the beginning of the second cycle utilizing both education and audit-and-feedback interventions, from October 16 to December 15, 2017, 35% of patients had IV therapy. At the end of the second cycle, 25% of patients had IV therapy, a 28% relative decrease in IV therapy rates. When both cycles are reviewed sequentially, IV therapy rates decreased from 31% to 25%, a relative reduction of IV usage of 19%. Conclusion: In this quality improvement project, an educational initiative for the interdisciplinary team alone did not reduce IV use in lower-acuity patients. Concurrent education and audit-and-feedback interventions were more effective than education alone in decreasing IV therapy in appropriately selected patients in a tertiary ED.

Introduction: Emergency departments (EDs) are overcrowded and patient acuity and volumes are ever-increasing. While changes to the flow of ED patient input and output are outside the control of frontline ED teams, the efficiency of ED throughput can be optimized. One widely studied intervention is the implementation of a physician liaison role to assist in managing overall ED flow. The Physician Float (PF) acts as a triage liaison, second physician for resuscitations, ED procedural sedation physician, and fields ED referral calls. This is a first-iteration proof-of-concept trial to plan, implement and evaluate if the PF role could decrease ED length of stay (LOS) by a goal of 30 minutes, over a four-week period, without adverse changes to left without being seen (LWBS) and bounce-back rates. Methods: The PF role was implemented as a scheduled emergency physician shift in the fall of 2017. Ongoing iterations of this role implementation are being reviewed for re-implementation. The primary outcome measure was ED LOS; secondary outcomes included time-to-physician initial assessment (PIA), EMS offload rates, and LWBS and 72-hour bounce-back rates. Qualitative data including patient concerns and physician feedback were also collected. Data were collected after the trial from a centralized, de-identified ED information system database with time-stamp quantifiers and compared to the following four-week time period where the shift is a regular ED physician shift at the same time. The ED physician and nursing team planned and implemented the PF role, then results were evaluated and shared with the wider ED staff in departmental grand rounds and quality council presentation formats, and recommendations were gathered from to adjust and strengthen future iterations of PF role implementation. Results: Descriptive statistics and Mann-Whitney and Median tests were calculated. On average there were 185 daily ED visits in the trial and comparison periods. Median ED LOS decreased by 12 minutes in the PF trial period (p<0.05). Furthermore, there was a 12 minute decreased ED LOS for all discharged patients (p<0.05). PIA time decreased by 13 minutes for patients that were admitted. The average percentage of EMS offloads within 60 min improved from 75% to 80.7% for admitted patients. LWBS and 72-hour bounce-back rates were unchanged. No additional patient concerns arose related to or during the trial. Physician feedback on the PF role was mainly positive. Conclusion: The defined role of a PF in an ED can decrease ED LOS, albeit not achieving the desired 30-minute reduction on the first iteration, this trial supported proof-of-concept for implementation of a PF role in a tertiary care centre ED. Further iterations are needed to evaluate the scalability and sustainability of this role.

Introduction: Unnecessary care is an increasingly commonly used term in medicine. Previous survey research suggests that definitions of unnecessary care vary within and among professional and patient groups. This research explores how emergency physicians and administrators understand the term unnecessary care. Methods: Site chiefs and emergency physicians in an Alberta region were recruited through email and online surveys respectively for a qualitative study. One hour one-on-one in-depth interviews explored understandings of unnecessary care within the emergency department (ED) context. Interview transcripts underwent thematic analysis. Results: Five physicians and seven site chiefs completed interviews. Two key themes emerged. First, interviewees conceptualized unnecessary care as inappropriate or non-urgent presentations. This patient-centric view raised non-urgent ED presentations as a health system problem with complex components, including: lack of public knowledge of healthcare resources, shrinking comfort and scope of community providers and patient willingness to utilize other resources. Despite concerns over non-urgent visits, interviewees expressed that these patients still need to be seen, assessed and managed. The second conceptualization focused on over-investigation (and to lesser extent, treatment). This physician-centric conceptualization identified issues around: variation in physician risk tolerance, established decision rules with the allowable miss rates, patient expectation for testing or physician feeling that the patient was owed something or that patient would not accept their diagnosis/treatment without testing. Additionally, interviewees described patient characteristics that may initiate more aggressive investigation (e.g., patient reliability, follow-up care access, etc.). An overarching concern about the connection between unnecessary care and wasted resources was identified. Additionally, interviewees emphasized that patient conversations are outside the scope of unnecessary care despite their possible implications for limited time resources. Conclusion: A range of concepts surrounding unnecessary care in the ED were identified. Further exploring nuances of these conceptualizations may inform and improve the effectiveness of campaigns seeking to improve efficiency in practice and reduce inappropriate care. Additionally, this work provides an impetus for developing clearer concepts of care within the ED.

Introduction: As utilization of CT imaging has risen dramatically, evidence-based decision rules and clinical decision support (CDS) tools have been developed to avoid unnecessary CT use in low risk patients. However, their ability to change physician practice has been limited to date, with a number of barriers cited. The purpose of this study was to identify the barriers and facilitators to CDS adoption following a local CDS implementation. Methods: All emergency physicians at 4 urban EDs and 1 urgent care center were randomized to voluntary evidence-based CT imaging CDS for patients with either mild traumatic brain injury (MTBI) or suspected pulmonary embolism (PE). CDS was integrated into the computerized physician order entry (CPOE) software and triggered whenever a CT scan for an eligible patient was ordered. Physicians in both the MTBI and PE arms were ranked according to their CDS use, and a stratified sampling strategy was used to randomly select 5 physicians from each of the low, medium and high CDS use tertiles in each study arm. Each physician was invited to participate in a 30-minute semi-structured interview to assess the barriers and facilitators to CDS use. Physician responses were reported using a thematic analysis. Results: A total of 202 emergency physicians were randomized to receive CDS for either MTBI or PE, triggering CDS 4561 times, and interacting with the CDS software 1936 times (42.4%). Variation in CDS use ranged from 0% to 88.9% of eligible encounters by physician. Fourteen physicians have participated in interviews to date, and data collection is ongoing. Physicians reported that CDS use was facilitated by their confidence in the evidence supporting the CDS algorithms and that it provided documentation to reduce medico-legal risk. CDS use was not impeded by concerns over missed diagnoses or patient expectations. Reported barriers to CDS use included suboptimal integration into the CPOE such as the inability to auto-populate test results, it disrupted the ordering process and was time consuming. A common concern was that CDS was implemented too late in workflow as most decision making takes place at the bedside. Physicians did not view CDS as infringing on physician autonomy, however they advised that CDS should be a passive educational option and should not automatically trigger for all physicians and eligible encounters. Conclusion: Physicians were generally supportive of CDS integration into practice, and were confident that CDS is an evidence-based way to reduce unnecessary CT studies. However, concerns were raised about the optimal integration of CDS into CPOE and workflow. Physicians also stated a preference to a passive educational approach to CDS rather than an automatic triggering mechanism requiring clinical documentation.

Introduction: Clinical decision support (CDS) has been implemented in many clinical settings in order to improve decision-making. Their potential to improve diagnostic accuracy and reduce unnecessary testing is well documented; however, their effectiveness in impacting physician practice in real world implementations has been limited by poor physician adherence. The objective of this systematic review and meta-regression was to establish the effectiveness of CDS tools on adherence and identify which characteristics of CDS tools increase physician use of and adherence. Methods: A systematic review and meta-analysis was conducted. MEDLINE, EMBASE, PsychINFO, the Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews were searched from inception to June 2017. Included studies examined CDS in a hospital setting, reported on physician adherence to or use of CDS, utilized a comparative study design, and reported primary data. All tool type was classified based on the Cochrane Effective Practice and Organization of Care (EPOC) classifications. Studies were stratified based on study design (RCT vs. observational). Meta-regression was completed to assess the different effect of characteristics of the tool (e.g. whether the tool was mandatory or voluntary, EPOC classifications). Results: A total of 3,359 candidate articles were identified. Seventy-two met inclusion criteria, of which 46 reported outcomes appropriate for meta-regression (5 RCTs and 41 observational studies). Overall, a trend of increased CDS use was found (pooled RCT OR: 1.36 [95% CI: 0.97-1.89]; pooled observational OR: 2.12 [95% CI: 1.75-2.56]).When type of tool is considered, clinical practice guidelines were superior compared to other interventions (p=.150). Reminders (p=.473) and educational interventions (p=.489) were less successful than other interventions. Multi-modal tools were not more successful that single interventions (p=.810). Lastly, voluntary tools may be supperior to than mandatory tools (p=.148). None of these results are statistically significant. Conclusion: CDS tools accompanied by a planned intervention increases physician utilization and adherence to the tool. Meta-regression found that clinical practice guidelines had the biggest impact on physician adherence although not statistically significant. Further research is required to understand the most effective intervention to maximize physician utilization of CDS tools.

Introduction: Physician access to presenting complaint information may lead to cherry picking if some patients are seen as more attractive than others. Our objective was to determine whether chief complaint CC descriptors are associated with differing wait time to MD, hence whether physicians preferentially see patients with selected presenting complaints. Methods: We collated administrative data on all Calgary ED patients from 2016. Those in CTAS categories 1 and 5 were excluded, as well as fast track patients (because of single coverage). We described most common chief complaint (CC) categories and their median wait time to MD, adjusted for ED arrival site, patient sex, triage acuity, and need for admission. Results: We studied 128,812 subjects (54% CTAS2, 46% CTAS34) with 56,243 males and 72,569 females. Mean age was 50.6 years (sd=20), and most common CC categories (%) were abdominal pain (22%), chest pain (14.6%), musculoskeletal problems (7.2%), flank pain (5.2%), URI/Fever (4.7%), dyspnea (4.6%), headache (4.6%), and back pain (4.0%). Median TTMD was 84 min and admission rate in the study cohort was 30.4%. Multiple linear regression modeling showed that, in addition to CC category and ED arrival site, CTAS level, female sex, and need for admission changed TTMD by 18.6 min (per CTAS level), 6.6 min, -19.2 min respectively. Based on adjusted TTMD, the least attractive CC categories (adjusted median TTMD) were constipation (104 min), back pain (103), Depression/anxiety (103), abdominal pain (102), and dizziness/sensory disturbance (98); while the most attractive were trauma (44 min), allergic reaction (46), stroke symptoms (49), palpitations (61), and overdoses (66). Conclusion: There is a larger than expected difference in waiting times associated with specific chief complaint categories. This has implications for the way that patients are assigned to physicians or perhaps the way that chief complaint data is transmitted.

Introduction: With a Canadian aging population, the prevalence of mild traumatic brain injury (mTBI) among elderly is increasing and the age criterion of the Canadian CT head rule (CCHR) is challenged by many emergency physicians. We evaluated if increasing the age criterion of the CCHR would maintain its validity. Methods: We conducted an historical cohort study using the medical charts of all patients 65 years old or more who consulted at a Level One Trauma Centre emergency department (ED) for a mTBI between 2010 and 2014. The main outcome measures were clinically important brain injury (CIBI) on Computed Tomography (CT) and the presence of the CCHR criteria. The clinical and radiological data collection was standardized. Univariate analysis was performed to measure the predictive capacities of modified age cut-offs at 70 and 75 years old. Results: Out of the 104 confirmed mTBI in this study, 32 (30,8%) had CIBI on CT scan. Sensitivity and specificity [C.I. 95%] of the CCHR were 100% [89.1 - 100] and 0% [0.0 5.0] for an age criterion of 65 years old and above; 100% [89.1 - 100] and 4,2% [0.9 11.7] for a modified criterion of 70 years old; 100% [89.1 - 100] and 13,9% [6.9 24.1] for 75 years old. Furthermore, for an age criterion of 80 and 85 years old, sensitivity was respectively 90,6% [75.0 98.0] and 75,0% [56.6 88.5]. Conclusion: In our cohort, increasing the age criterion of the CCHR for minor head injury to 75 years old would benefit ED by further reducing CT scans without missing CIBI. A larger prospective study is indicated to confirm the proposed modification.

Introduction: Introduction: A variety of pain assessment tools exist for children, however none of the current scales were created specifically for family use. Further, none provide direct guidance with regards to pain treatment threshold. This study aimed to validate a novel, three faced, coloured coded (red, yellow, green), family-friendly pain tool, the Stoplight Pain Scale, by comparing it to the widely accepted and validated Faces Pain Scale-Revised (FPS-R). This novel tool has the capability to guide families with regards to treatment, as well as measure pain. Methods: Methods: A prospective observational cohort study was conducted at the Stollery Childrens Hospital emergency department (ED) (Edmonton, Alberta) from November, 2014 to February, 2017. Demographic information was collected, and patients (3-12 years) and their caregivers were asked to rate their pain using the novel Stoplight Pain Scale as well as the FPS-R. Pain was measured at presentation to the ED, immediately following painful procedures, and thirty minutes after analgesia administration. Patients and their caregivers also indicated their preferred scale for assessing pain. Results: Results: A purposeful random sample of 227 patients were included for analyses; 61/227 (26.9%) of patients were 3-5 years old and 166/227 (73.1%)were 6-12 years old. 53/227 (23.3%) of patients had been previously hospitalized. Correlation between the two pain scales was consistently fair to moderate; using Kappa Statistics, a baseline correlation for Stoplight and FPS-R was fair for both caregivers (0.38, 95% CI 0.28 0.48) and patients (0.36 95% CI 0.27-0.45). The Stoplight Pain Scale had fair to moderate correlation between caregiver and patient scores, (0.37, 95% CI 0.27-0.47), compared to FPS-R which showed poor to fair agreement between caregiver and child scores (0.20, 95% CI 0.12-0.29). Regardless of age or hospitalization status, 64% of patients (139/218) and 54% caregivers (118/220) preferred the Stoplight Pain scale (p=0.001). Conclusion: Conclusions: The Stoplight Pain Scale correlates moderately well with FPS-R, a validated pain assessment tool for children and shows good correlation between patients and caregivers assessment of reported pain. The Stoplight Pain Scale is a simple, easy to administer tool that may have a role in empowering family involvement in ED pain management. Future research should focus on at-home study of the tool.
