Objectives: Lengthy emergency department (ED) wait times caused by hospital access block is a growing concern for the Canadian health care system. Our objective was to quantify the impact of alternate-level-of-care on hospital access block and evaluate the likely effects of multiple interventions on ED wait times.

Methods: Discrete-event simulation models were developed to simulate patient flows in EDs and acute care of six Canadian hospitals. The model was populated with administrative data from multiple sources (April 2017-March 2018). We simulated and assessed six different intervention scenarios' impact on three outcome measures: (1) time waiting for physician initial assessment, (2) time waiting for inpatient bed, and (3) patients who leave without being seen. We compared each scenario's outcome measures to the baseline scenario for each ED.

Results: Eliminating 30% of medical inpatients' alternate-level-of-care days reduced the mean time waiting for inpatient bed by 0.25 to 4.22 h. Increasing ED physician coverage reduced the mean time waiting for physician initial assessment (∆ 0.16-0.46 h). High-quality care transitions targeting medical patients lowered the mean time waiting for inpatient bed for all EDs (∆ 0.34-6.85 h). Reducing ED visits for family practice sensitive conditions or improving continuity of care resulted in clinically negligible reductions in wait times and patients who leave without being seen rates.

Conclusions: A moderate reduction in alternate-level-of-care hospital days for medical patients could alleviate access block and reduce ED wait times, although the magnitude of reduction varies by site. Increasing ED physician staffing and aligning physician capacity with inflow demand could also decrease wait time. Operational strategies for reducing ED wait times should prioritize resolving output and throughput factors rather than input factors.

Purpose: This is the first study to take an in-depth qualitative approach to identify motivating factors for caregivers who chose the paediatric emergency virtual care option in Canada during the SARS-CoV-2 pandemic. The role that virtual care may play moving forward is also considered.

Methods: Between May 2020 and May 2021, 773 respondents attending the virtual clinic completed a follow-up survey with open-ended questions. For qualitative content analysis, comments were coded and analysed until thematic saturation was reached. Sub-codes were subsumed into major coding categories to identify themes.

Results: Three major themes, including safety, reassurance and convenience, and an overarching theme of satisfaction emerged from this analysis. Paediatric virtual clinic use was motivated in part by a desire to avoid the hospital environment. In-person Emergency Department visits were reported to be challenging and stressful, particularly due to perceived infection risk. Respondents appreciated that the clinic provided reassurance by assisting in navigating the healthcare system during a time of uncertainty and felt the virtual option allowed them to use healthcare resources responsibly. The convenience and ease of access to virtual care allowed for improved family-centred care in vulnerable populations. The overarching theme of satisfaction was emphasized by numerous comments for this service to be offered post-pandemic.

Conclusion: Our study indicates that virtual care was an attractive option for caregivers due to the safety, reassurance, and convenience provided. The strong patient desire for continued availability post-pandemic will be important considerations in this rapidly developing area of care.

Objectives: We hypothesized that an association exists between satisfaction with ED mental health care delivery and patient and system characteristics. Primary: To evaluate overall satisfaction with ED mental health care delivery. Secondary: To explore aspects of ED mental health care delivery associated with general satisfaction, and patient and ED visit characteristic associated with total satisfaction scores and reported care experience themes.

Methods: We enrolled patients < 18 years of age presenting with a mental health concern between February 1, 2020 and January 31, 2021, to two pediatric EDs in Alberta, Canada. Satisfaction data were collected using the Service Satisfaction Scale, a measure of global satisfaction with mental health services. Association of general satisfaction with ED mental health care was evaluated using Pearson's correlation coefficient and variables associated with total satisfaction score was assessed using multivariable regression analyses. Inductive thematic analysis of qualitative feedback identified satisfaction and patient experience themes.

Results: 646 participants were enrolled. 71.2% were Caucasian and 56.3% female. Median age was 13 years (IQR 11-15). Parents/caregivers (n = 606) and adolescents (n = 40) were most satisfied with confidentiality and respect in the ED and least satisfied with how ED services helped reduce symptoms and/or problems. General satisfaction was associated with perceived amount of help received in the ED (r = 0.85) and total satisfaction with evaluation by a mental health team member (p = 0.004) and psychiatrist consultation (p = 0.05). Comments demonstrated satisfaction with ED provider attitudes and interpersonal skills and dissatisfaction with access to mental health and addictions care, wait time, and the impact of COVID-19.

Conclusions: There is a need to improve ED mental health care delivery, with a focus on timely access to ED mental health providers. Access to outpatient/community-based mental health care is needed to complement care received in the ED and to provide continuity of care for youth with mental health concerns.

Background: Residency training is associated with risks of burnout and impaired well-being. This may be due to multiple factors, including navigating various transitions. Chief among these is the transition to independent practice which, in Canada, involves a certification exam administered by the Royal College of Physicians and Surgeons of Canada or the College of Family Physicians of Canada. This qualitative study explored the experience of residents in their examination year, including residents impacted by pandemic-related examination postponment, to understand how these experiences may impact residents' well-being.

Methods: Qualitative description methodology was used for this study. Participants were residents and physicians in independent practice from McMaster University and the University of Toronto. In depth, semi-structured, one-on-one interviews were conducted by one of the investigators. Each was transcribed, reviewed, and coded by two members of the investigating team.

Results: Five themes were identified. Examinations were perceived to be a significant stressor, and the extent of preparation involved was viewed as a threat to one's physical and mental well-being. Participants identified a culture of fear surrounding the exam, as well as a perception that exam preparation requires significant sacrifice which can exacerbate the impacts of the exam year. Personal and professional supports were identified as important protective factors.

Conclusion: This study has identified unique challenges in the examination year, and its impact on the well-being of residents immediately before they enter independent practice. Residents also experienced significant learning and a sense of accomplishment through their preparation for the examination. The COVID-19 pandemic had a unique impact on one cohort of residents. This should prompt medical education institutions to examine the support provided to residents, the culture surrounding certification examinations, and mitigation strategies for future examination disruptions.

Purpose: Trauma team leaders (TTLs) have traditionally been general surgeons; however, some trauma centres use a mixed model of care where both surgeons and non-surgeons (primarily emergency physicians) perform this role. The objective of this multicentre study was to provide a well-powered study to determine if TTL specialty is associated with mortality among major trauma patients.

Methods: Data were collected from provincial trauma registries at six level 1 trauma centres across Canada over a 10-year period. We included adult trauma patients (age ≥ 18 yrs) who triggered the highest-level trauma activation. The primary outcome was the difference in risk-adjusted in-hospital mortality for trauma patients receiving initial care from a surgeon versus a non-surgeon TTL.

Results: Overall, 12,961 major trauma patients were included in the analysis. Initial treatment was provided by a surgeon TTL in 57.8% (n = 7513) of cases, while 42.2% (n = 5448) of patients were treated by a non-surgeon TTL. Unadjusted mortality occurred in 11.6% of patients in the surgeon TTL group and 12.7% of patients in the non-surgeon TTL group (OR 0.87, 95% CI 0.78-0.98, p = 0.02). Risk-adjusted mortality was not significantly different between patients cared for by surgeon and non-surgeon TTLs (OR 0.92, 95% CI 0.80-1.06, p = 0.23). Furthermore, we did not observe differences in risk-adjusted mortality for any of the subgroups evaluated.

Conclusions: After risk adjustment, there was no difference in mortality between trauma patients treated by surgeon or non-surgeon TTLs. Our study supports emergency physicians performing the role of TTL at level 1 trauma centres.

Objectives: The objective of this study was to synthesize indication-based evidence for N₂O for distress and pain in children.

Study design: We included trials of N₂O in participants 0-21 years, reporting distress or pain for emergency department procedures. The primary outcome was procedural distress. Where meta-analysis was not possible, we used Tricco et al.'s classification of "neutral" (p ≥ 0.05), "favorable," or "unfavorable" (p < 0.05, supporting N₂O or comparator, respectively). We used the Cochrane Collaboration's Risk of Bias tool and the Grading of Recommendations Assessment, Development, and Evaluation system to evaluate risk of bias and quality of evidence, respectively.

Results: We included 30 trials. For pain using the Visual Analog Scale (0-100 mm) during IV insertion, 70% N₂O (delta:-16.5; 95%CI:-28.6 to -4.4; p = 0.008; three trials; I² = 0%) and 50% N₂O plus eutectic mixture of local anesthetics (EMLA) (delta:-1.2; 95%CI:-2.1 to -0.3; p = 0.007; two trials; I² = 43%) were superior to EMLA. 50% N₂O was not superior to EMLA (delta:-0.4; 95%CI:-1.2 to 0.3; p = 0.26; two trials; I² = 15%). For distress and pain during laceration repair, N₂O was "favorable" versus each of SC lidocaine, oxygen, and oral midazolam but "neutral" versus IV ketamine (five trials). For distress and pain during fracture reduction (three trials), N₂O was "neutral" versus each of IM meperidine plus promethazine, regional anesthesia, and IV ketamine plus midazolam. For distress and pain during lumbar puncture (one trial), N₂O was "favorable" versus oxygen. For distress and pain during urethral catheterization (one trial), N₂O was "neutral" versus oral midazolam. For pain during intramuscular injection (one trial), N₂O plus EMLA was "favorable" versus N₂O and EMLA alone. Common adverse effects of N₂O included nausea (4.4%), agitation (3.7%), and vomiting (3.6%) AEs were less frequent with N₂O alone (278/1147 (24.2%)) versus N₂O plus midazolam (48/52 (92.3%)) and N₂O plus fentanyl (123/201 (61.2%)).

Conclusions: There is sufficient evidence to recommend N₂O plus topical anesthetic for IV insertion and laceration repair. Adverse effects are greater when combined with other sedating agents.

Introduction: Over the last two decades, there has been a steady rise in severe maternal morbidity and pregnancy-related deaths in Canada and the USA. The Modified Early Obstetric Warning System (MEOWS) is a risk stratification tool designed to predict severe maternal morbidity and mortality and has been validated for use in obstetrical wards. The objective of this study was to determine if MEOWS could accurately identify patients at risk of severe maternal morbidity and mortality in the ED setting.

Methods: This was a chart review of patients presenting to an academic tertiary care centre (annual ED census 65,000) with a postpartum complaint within 6 weeks of delivery between May 2020 and March 2022. The exposure was the presence of a trigger, defined as one severely abnormal (red) or two mildly abnormal (yellow) physiological measurements during the ED visit. The diagnostic accuracy of the tool to identify patients at risk of severe maternal morbidity severe maternal morbidity or mortality was estimated by calculating the sensitivity, specificity, positive predictive value and negative predictive value.

Results: Two hundred and sixty-seven patients were included, of which 21 (7.9%) met the criteria for severe maternal morbidity. There were no maternal deaths. Overall, the sensitivity of the MEOWS tool was 85.7% (95% CI 63.7-97.0%), specificity was 67.9% (95% CI 61.7-73.7%), positive predictive value was 18.6% (95% CI 15.1-22.7%), and negative predictive value was 98.2% (95% CI 95.1-99.4%). Severe preeclampsia and eclampsia were the most common outcome category of severe maternal morbidity, representing 16 (76.2%) cases. Most patients (86.5%) were discharged directly from the ED, and 90.0% did not return within 30 days.

Conclusions: This study is the first to explore the utility of MEOWS in postpartum ED patients. The presence of a MEOWS trigger at ED triage or the first ED nursing assessment was associated with severe maternal morbidity. Thus, MEOWS may be a valuable tool to identify postpartum patients at risk of severe outcomes early in an ED visit.
