Carpenter CR, Lee S, Kennedy M, Arendts G, Schnitker L, Eagles D, Mooijaart S, Fowler S, Doering M, LaMantia MA, Han JH, Liu SW. Delirium detection in the emergency department: A diagnostic accuracy meta-analysis of history, physical examination, laboratory tests, and screening instruments. Acad Emerg Med 2024. [PMID: 38757369 DOI: 10.1111/acem.14935] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 04/13/2024] [Accepted: 04/15/2024] [Indexed: 05/18/2024]
Abstract
INTRODUCTION Geriatric emergency department (ED) guidelines emphasize timely identification of delirium. This article updates previous diagnostic accuracy systematic reviews of history, physical examination, laboratory testing, and ED screening instruments for the diagnosis of delirium as well as test-treatment thresholds for ED delirium screening. METHODS We conducted a systematic review to quantify the diagnostic accuracy of approaches to identify delirium. Studies were included if they described adults aged 60 or older evaluated in the ED setting with an index test for delirium compared with an acceptable criterion standard for delirium. Data were extracted and studies were reviewed for risk of bias. When appropriate, we conducted a meta-analysis and estimated delirium screening thresholds. RESULTS Full-text review was performed on 55 studies and 27 were included in the current analysis. No studies were identified exploring the accuracy of findings on history or laboratory analysis. While two studies reported clinicians accurately rule in delirium, clinician gestalt is inadequate to rule out delirium. We report meta-analysis on three studies that quantified the accuracy of the 4 A's Test (4AT) to rule in (pooled positive likelihood ratio [LR+] 7.5, 95% confidence interval [CI] 2.7-20.7) and rule out (pooled negative likelihood ratio [LR-] 0.18, 95% CI 0.09-0.34) delirium. We also conducted meta-analysis of two studies that quantified the accuracy of the Abbreviated Mental Test-4 (AMT-4) and found that the pooled LR+ (4.3, 95% CI 2.4-7.8) was lower than that observed for the 4AT, but the pooled LR- (0.22, 95% CI 0.05-1) was similar. Based on one study the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) is the superior instrument to rule in delirium. The calculated test threshold is 2% and the treatment threshold is 11%. CONCLUSIONS The quantitative accuracy of history and physical examination to identify ED delirium is virtually unexplored. The 4AT has the largest quantity of ED-based research. Other screening instruments may more accurately rule in or rule out delirium. If the goal is to rule in delirium then the CAM-ICU or brief CAM or modified CAM for the ED are superior instruments, although the accuracy of these screening tools are based on single-center studies. To rule out delirium, the Delirium Triage Screen is superior based on one single-center study.

Abstract
BACKGROUND Emergency department (ED) crowding is a significant challenge to providing safe and quality care to patients. We know that hospital and ED crowding is exacerbated on Mondays because fewer in-patients are discharged on the weekend. We evaluated barriers and potential solutions to improve in-patient flow and diminished weekend discharges, in hopes of decreasing the severe ED crowding observed on Mondays. METHODS In this observational study, we conducted interviews of (a) leaders at The Ottawa Hospital, a major academic health sciences centre (nursing, allied health, physicians), and (b) leaders of community facilities (long-term care and chronic hospital) that receive patients from the hospital, and (c) home care. Each interview was conducted individually and addressed perceived barriers to the discharge of hospital in-patients on weekends as well as potential solutions. An inductive thematic analysis was conducted whereby themes were organized into a summary table of barriers and solutions. RESULTS We interviewed 40 leaders including 30 nursing, physician, and allied health leaders from the hospital as well as 10 senior personnel from community facilities and home care. Many barriers to weekend discharges were identified, highlighting that this problem is complex with many interdependent internal and external factors. Fortunately, many specific potential solutions were suggested, in immediate, short-term and long-term time horizons. While many solutions require additional resources, others require a culture change whereby hospital and community stakeholders recognize that services must be provided consistently, seven days a week. INTERPRETATION We have identified the complex and interdependent barriers to weekend discharges of in-patients. There are numerous specific opportunities for hospital staff and services, physicians, and community facilities to provide the same patient care on weekends as on weekdays. This will lead to improved patient flow and safety, and to decreased ED crowding on Mondays.

How well do ED physician practices align with the CAEP acute atrial fibrillation checklist for stroke prevention and disposition? CAN J EMERG MED 2024; 26:327-332. [PMID: 38530599 DOI: 10.1007/s43678-024-00676-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 02/29/2024] [Indexed: 03/28/2024]
Abstract
OBJECTIVES Acute atrial fibrillation (AF)/flutter (AFL) is a common emergency department (ED) presentation. In 2021, an updated version of CAEP's Acute AF/AFL Best Practices Checklist was published, seeking to guide management. We assessed the alignment with and safety of application of the Checklist, regarding stroke prevention and disposition. METHODS This health records review included adults presenting to two tertiary care academic EDs between January and August 2022 with a diagnosis of acute AF/AFL. Patients were excluded if their initial heart rate was < 100 or if they were hospitalized. Data extracted included: demographics, CHADS-65 score, clinical characteristics, ED treatment and disposition, and outpatient prescriptions and referrals. Our primary outcome was the proportion of patient encounters with one or more identified safety issues. Each case was assessed according to seven predetermined criteria from elements of the CAEP Checklist and either deemed "safe" or to contain one or more safety issues. We used descriptive statistics with 95% confidence intervals. RESULTS 358 patients met inclusion criteria. The mean age was 66.9 years, 59.2% were male and 77.4% patients had at least one of the CHADS-65 criteria. 169 (47.2%) were not already on anticoagulation and 99 (27.6%) were discharged home with a new prescription for anticoagulation. The primary outcome was identified in 6.4% (95% CI 4.3-9.5) of encounters, representing 28 safety issues in 23 individuals. The safety concerns included: failure to prescribe anticoagulation when indicated (n = 6), inappropriate dosing of a direct oral anticoagulant (DOAC) (n = 2), inappropriate prescription of rate or rhythm control medication (n = 9), and failure to recommend appropriately timed follow-up for new rate control medication (n = 11). CONCLUSIONS There was a very high level of ED physician alignment with CAEP's Best Practices Checklist regarding disposition and stroke prevention. There are opportunities to further improve care with respect to recommendation of anticoagulation and reducing inappropriate prescriptions of rate or rhythm medications.

Abstract
OBJECTIVES Acute atrial fibrillation and flutter (AF/AFL) are common arrhythmias treated in the emergency department (ED). The 2021 CAEP Best Practices Checklist provides clear recommendations for management of patients with acute AF/AFL. This study aimed to evaluate physician compliance to Checklist recommendations for risk assessment and ED management of AF/AFL. METHODS This health records review assessed the management of adult patients presenting to two tertiary care EDs for management of acute AF/AFL from January to August, 2022. All ECGs demonstrating AF/AFL with a heart rate greater than 100 were compiled to capture primary and secondary causes. All visits were assessed for rate and rhythm control management, adverse events, return to ED, and safety criteria. Study physicians classified safety criteria from the Checklist into high and moderate concerns. The primary outcome was the proportion of cases with safety concerns and adverse events occurring during management in the ED. Data were analyzed using simple descriptive statistics. RESULTS We included 429 patients with a mean age of 67.7 years and 57.1% male. ED management included rate control (20.4%), electrical (40.1%), and pharmacological (20.1%) cardioversion. Adverse events occurred in 9.5% of cases: 12.5% in rate control, 13.4% in electrical cardioversion, and 6.9% in pharmacologic cardioversion. Overall, 7.9% of cases had management safety concerns. Moderate safety concerns occurred in 4.9% of cases including failure to attain recommended heart rate at time of discharge (3.9%). Severe concerns were identified in 3.0% of cases including failure to cardiovert unstable patients (1.2%). The 30-day return-to-ED rate was 16.5% secondary to AF/AFL. CONCLUSION ED management of AF/AFL was consistent with the CAEP Checklist and was safe overall. Opportunities for optimizing care include attaining recommended targets during rate control, avoidance of calcium channel and beta blockers in patients with systolic dysfunction, and earlier cardioversion for clinically unstable patients.

Abstract
OBJECTIVE Physicians vary in their computed tomography (CT) scan usage. It remains unclear how physician gender relates to clinical practice or patient outcomes. The aim of this study was to assess the association between physician gender and decision to order head CT scans for older emergency patients who had fallen. METHODS This was a secondary analysis of a prospective observational cohort study conducted in 11 hospital emergency departments (EDs) in Canada and the United States. The primary study enrolled patients who were 65 years and older who presented to the ED after a fall. The analysis evaluated treating physician gender adjusted for multiple clinical variables. Primary analysis used a hierarchical logistic regression model to evaluate the association between treating physician gender and the patient receiving a head CT scan. Secondary analysis reported the adjusted odds ratio (OR) for diagnosing intracranial bleeding by physician gender. RESULTS There were 3663 patients and 256 physicians included in the primary analysis. In the adjusted analysis, women physicians were no more likely to order a head CT than men (OR 1.26, 95% confidence interval 0.98-1.61). In the secondary analysis of 2294 patients who received a head CT, physician gender was not associated with finding a clinically important intracranial bleed. CONCLUSIONS There was no significant association between physician gender and ordering head CT scans for older emergency patients who had fallen. For patients where CT scans were ordered, there was no significant relationship between physician gender and the diagnosis of clinically important intracranial bleeding.

Abstract
AIMS Patients undergoing emergency general surgery are at high risk of complications and death. Our objectives were to estimate the incidence of emergency general surgery in a Swiss University Hospital, to describe the characteristics and outcomes of patients undergoing such procedures, and to study the impact of age on clinical outcomes. METHODS This was a retrospective cohort study of adult patients who visited the emergency department (ED) of Geneva University Hospitals between January 2015 and December 2019. Routinely collected data were extracted from electronic medical records. The primary outcome was the incidence of emergency general surgery among patients visiting the emergency department, defined as general surgery within three days of emergency department admission. We also assessed demographic characteristics, mortality, intensive care unit admission and patient disposition. Multivariable log-binomial regression was used to study the associations of age with intensive care unit (ICU) admission, one-year mortality and dependence at discharge. Age was modelled as a continuous variable using restricted cubic splines and we compared older patients (75th percentile) with younger patients (25th percentile). RESULTS Between January 2015 and December 2019, a total of 310,914 emergency department visits met our inclusion criteria. Among them, 3592 patients underwent emergency general surgery within 3 days of emergency department admission, yielding an annual incidence of 116 events per 10,000 emergency department visits (95% CI: 112-119), with a higher incidence in females and young patients. Overall, 5.3% of patients were admitted to ICU, 7.8% were dependent on rehabilitation or assisted living at discharge and 4.8% were dead after one year. Older patients had a higher risk of ICU admission (adjusted risk ratio (aRR) 2.9 [1.5-5.4]), dependence at discharge (aRR 15.3 [5.5-42.4]) and one-year mortality (aRR 5.4 [2.2-13.4]). CONCLUSION Emergency department visits resulting in emergency general surgery are frequent, but their incidence decreases with patient age. Mortality, ICU admission and dependence at discharge following emergency general surgery are more frequent in older patients. Taking into account the increased risk for older patients, a shared process is appropriate for making more informed decisions about their options for care.

Abstract
INTRODUCTION Teaching point-of-care ultrasonography (PoCUS) to medical students is resource intensive. Peer-assisted learning, where the teacher can be a medical student, may be a feasible alternative to expert-led learning. The objective of this systematic review and meta-analysis was to compare the PoCUS performance assessments of medical students receiving peer-assisted vs expert-led learning. METHODS This study was submitted to PROSPERO (CRD42023383915) and reported with PRISMA guidelines. MEDLINE, Embase, ERIC, Education Source, Scopus, and Web of Science were searched from inception to November 2022. Inclusion criteria were studies comparing peer-assisted vs expert-led PoCUS teaching for undergraduate medical students. The primary outcome was performance assessment of PoCUS skills. Two reviewers independently screened citations and extracted data. The Cochrane risk-of-bias tool for randomized trials was used to assess study quality. Studies were included in the meta-analysis if mean performance assessment scores with standard deviations and sample sizes were available. A random-effects meta-analysis was conducted to estimate the accuracy score of practical knowledge test for each group. A meta-regression evaluated difference in mean scores. RESULTS The search yielded 2890 citations; 1417 unique citations remained after removing duplicates. Nine randomized-controlled studies conducted in Germany, USA, and Israel, with 593 participants, were included in the meta-analysis. The included studies assessed teaching of abdominal, cardiac, thoracic, musculoskeletal, and ocular PoCUS skills. Most studies had some risk-of-bias concerns. The estimate accuracy score after weighting is 0.56 (95% CI [0.47, 0.65]) for peer-assisted learning and 0.59 (95% CI [0.49, 0.69]) for expert-led learning. The regression coefficient estimate is 0.0281 (95% CI [- 0.1121, 0.1683]); P value is 0.69. CONCLUSION This meta-analysis found that peer-assisted learning was a reasonable alternative to expert-led learning for teaching PoCUS skills to medical students.

Abstract
BACKGROUND We sought to improve the immediate and subsequent care of emergency department (ED) patients with acute atrial fibrillation (AF) and flutter (AFL) by implementing the principles of the Canadian Association of Emergency Physicians AF/AFL Best Practices Checklist. METHODS This cohort study included 3 periods: before (7 months), intervention introduction (1 month), and after (7 months), and was conducted at a major academic centre. We included patients who presented with an episode of acute AF or AFL and used multiple strategies to support ED adoption of the Canadian Association of Emergency Physicians checklist. We developed new cardiology rapid-access follow-up processes. The main outcomes were unsafe and suboptimal treatments in the ED. RESULTS We included 1108 patient visits, with 559 in the before and 549 in the after period. In a comparison of the periods, there was an increase in use of chemical cardioversion (20.6% vs 25.0%; absolute difference [AD], 4.4%) and in electrical cardioversion (39.2% vs 51.2%; AD, 12.0%). More patients were discharged with sinus rhythm restored (66.9% vs 75.0%; AD, 8.1%). The proportion seen in a follow-up cardiology clinic increased from 24.2% to 39.9% (AD, 15.7%) and the mean time until seen decreased substantially (103.3 vs 49.0 days; AD, -54.3 days). There were very few unsafe cases (0.4% vs 0.7%) and, although there was an increase in suboptimal care (19.5% vs 23.1%), overall patient outcomes were excellent. CONCLUSIONS We successfully improved the care for ED patients with acute AF/AFL and achieved more frequent and more rapid cardiology follow-up. Although cases of unsafe management were uncommon and patient outcomes were excellent, there are opportunities for physicians to improve their care of acute AF/AFL patients.

Abstract
INTRODUCTION Electrical cardioversion for atrial fibrillation/atrial flutter (AF/AFL) is common in the ED. Our previous work showed that hypotension and respiratory events were important adverse events that occurred in patients undergoing electrical cardioversion for AF/AFL. The purpose of this study was to examine if (1) beta-blockers or calcium channel blocker use prior to ECV were associated with hypotension and (2) medications used for procedural sedation were associated with respiratory events. METHODS This was a secondary analysis of pooled study data from four previous multicentred studies on AF/AFL. We conducted a multivariable logistic regression to examine predictors of hypotension and respiratory adverse events. RESULTS There were 1736 patients who received ECV. A hypotensive event occurred in 62 (3.6%) patients. There was no significant difference in the odds of a hypotensive event in patients who received a beta-blocker or calcium channel blocker in the ED compared to no rate control. Procedural sedation with fentanyl (OR 2.01 95% CI 1.15-3.51) and home beta-blocker use (OR 1.92, 95% CI 1.14-3.21) were significantly associated with hypotensive events. A respiratory event occurred in 179 (10.3%) patients. Older age (OR 2.02, 95% CI 1.30- 3.15) and receiving midazolam for procedural sedation were found to be significantly associated with respiratory events (OR 1.99, 95% CI 1.02-3.88). CONCLUSION Beta-blocker or calcium channel blocker use prior to ECV for AF/AFL was not associated with hypotension. However, sedation with fentanyl and home beta-blocker use was associated with hypotension. The use of midazolam for procedural sedation was significantly associated with respiratory events.

Abstract
INTRODUCTION Frailty is associated with adverse outcomes among patients attending emergency departments (EDs). While multiple frailty screens are available, little is known about which variables are important to incorporate and how best to facilitate accurate, yet prompt ED screening. To understand the core requirements of frailty screening in ED, we conducted an international, modified, electronic two-round Delphi consensus study. METHODS A two-round electronic Delphi involving 37 participants from 10 countries was undertaken. Statements were generated from a prior systematic review examining frailty screening instruments in ED (logistic, psychometric and clinimetric properties). Reflexive thematic analysis generated a list of 56 statements for Round 1 (August-September 2021). Four main themes identified were: (i) principles of frailty screening, (ii) practicalities and logistics, (iii) frailty domains and (iv) frailty risk factors. RESULTS In Round 1, 13/56 statements (23%) were accepted. Following feedback, 22 new statements were created and 35 were re-circulated in Round 2 (October 2021). Of these, 19 (54%) were finally accepted. It was agreed that ideal frailty screens should be short (<5 min), multidimensional and well-calibrated across the spectrum of frailty, reflecting baseline status 2-4 weeks before presentation. Screening should ideally be routine, prompt (<4 h after arrival) and completed at first contact in ED. Functional ability, mobility, cognition, medication use and social factors were identified as the most important variables to include. CONCLUSIONS Although a clear consensus was reached on important requirements of frailty screening in ED, and variables to include in an ideal screen, more research is required to operationalise screening in clinical practice.

Abstract
This clinical review is intended to assist emergency physicians manage patients who present to the emergency department (ED) with acute/recent-onset atrial fibrillation (AF) or flutter (AFL). This article is based primarily on the 2021 Canadian Association of Emergency Physicians (CAEP) Acute Atrial Fibrillation/Flutter Best Practices Checklist. We encourage readers to download the open access CAEP Checklist article (https://link.springer.com/article/10.1007/s43678-021-00167-y) and the free smartphone app (CAEP Atrial Fibrillation Guide). We focus on four key elements of ED care: assessment and risk stratification, rate and rhythm control, short-term and long-term stroke prevention, and disposition and follow-up. It is important to determine if AF/AFL with rapid ventricular response is a primary arrhythmia or secondary to medical causes. While it is unusual for patients with primary AF to be unstable, urgent cardioversion is occasionally required. The criteria for when cardioversion is safe have recently changed and it is essential that physicians are well versed in them. When rhythm control is not safe, provide effective and safe IV rate control. When rhythm control is safe, either pharmacological or electrical cardioversion acceptable, per patient and physician preference. Rapid ventricular pre-excitation (Wolff-Parkinson-White Syndrome) usually, but not always, requires urgent electrical cardioversion. ED physicians should prescribe oral anticoagulants at discharge if indicated. No specific direct oral anticoagulant is preferred, and references should be freely consulted for optimal dosing. Hospital admission is rarely required for acute AF/AFL patients, who should be given good discharge instructions.

Abstract
BACKGROUND Ground-level falls are common among older adults and are the most frequent cause of traumatic intracranial bleeding. The aim of this study was to derive a clinical decision rule that safely excludes clinically important intracranial bleeding in older adults who present to the emergency department after a fall, without the need for a computed tomography (CT) scan of the head. METHODS This prospective cohort study in 11 emergency departments in Canada and the United States enrolled patients aged 65 years or older who presented after falling from standing on level ground, off a chair or toilet seat, or out of bed. We collected data on 17 potential predictor variables. The primary outcome was the diagnosis of clinically important intracranial bleeding within 42 days of the index emergency department visit. An independent adjudication committee, blinded to baseline data, determined the primary outcome. We derived a clinical decision rule using logistic regression. RESULTS The cohort included 4308 participants, with a median age of 83 years; 2770 (64%) were female, 1119 (26%) took anticoagulant medication and 1567 (36%) took antiplatelet medication. Of the participants, 139 (3.2%) received a diagnosis of clinically important intracranial bleeding. We developed a decision rule indicating that no head CT is required if there is no history of head injury on falling; no amnesia of the fall; no new abnormality on neurologic examination; and the Clinical Frailty Scale score is less than 5. Rule sensitivity was 98.6% (95% confidence interval [CI] 94.9%-99.6%), specificity was 20.3% (95% CI 19.1%-21.5%) and negative predictive value was 99.8% (95% CI 99.2%-99.9%). INTERPRETATION We derived a Falls Decision Rule, which requires external validation, followed by clinical impact assessment. Trial registration: ClinicalTrials. gov, no. NCT03745755.

Abstract
STUDY OBJECTIVE The inherent pressures of high-acuity, critical illness in the emergency department create a unique environment whereby acute goals-of-care discussions must be had with patients or substitute decision makers to rapidly decide between divergent treatment paths. Among university-affiliated hospitals, resident physicians are often conducting these highly consequential discussions. This study aimed to use qualitative methods to explore how emergency medicine residents make recommendations regarding life-sustaining treatments during acute goals-of-care discussions in critical illness. METHODS Using qualitative methods, semistructured interviews were conducted with a purposive sample of emergency medicine residents in Canada from August to December 2021. Inductive thematic analysis of the interview transcripts was conducted using line-by-line coding, and key themes were identified through comparative analysis. Data collection continued until thematic saturation was reached. RESULTS Seventeen emergency medicine residents from 9 Canadian universities were interviewed. Two factors guided residents' treatment recommendations (a duty to provide a recommendation and the balance between disease prognosis and patient values). Three factors influenced residents' comfort when making recommendations (time constraints, uncertainty, and moral distress). CONCLUSION While conducting acute goals-of-care discussions with critically ill patients or their substitute decision makers in the emergency department, residents felt a sense of duty to provide a recommendation informed by an intersection between the patient's disease prognosis and the patient's values. Their comfort in making these recommendations was limited by time constraints, uncertainty, and moral distress. These factors are important for informing future educational strategies.

Abstract
BACKGROUND Older trauma patients have a higher mortality yet are more likely to be under-triaged compared to younger patients. Studies have suggested that current trauma team activation criteria are suboptimal for older patients. OBJECTIVES The objective was to describe trauma care delivered, patient outcomes, and to identify variables independently associated with mortality. METHODS We performed a health records review from 2014 to 2020 of older (age ≥ 65 years) trauma patients presenting to a level one trauma centre with any of the following: injury severity score (ISS) > 12, and all trauma team activations or admission to the trauma ward. The primary outcome was 30-day all-cause mortality. Secondary outcomes included injury mechanism and trauma care delivered. Multivariable logistic regression was used to identify factors independently associated with 30-day all-cause mortality. Multiple imputation was used to deal with missing data. RESULTS We enrolled 1,380 patients (mean age 80 years, mean ISS 18); 26.8% had multimorbidity (≥ 2 chronic conditions) and 65.9% met criteria for polypharmacy (≥ 5 medications). The most common mechanism was fall from standing height (61.1%). Thirty-day all-cause mortality occurred in 239 (17.3%) patients. A Glasgow coma scale (GCS) < 15 (odds ratio [OR] = 5.55; 95% CI 3.73-8.24), ISS > 15 (OR = 3.75, 95% CI 2.35-6.01), age ≥ 85 years (OR = 2.04, 95% CI 1.29-3.22), anticoagulation with a direct oral anticoagulant (DOAC) or warfarin (OR = 1.59, 95% CI 1.08-2.35) and multimorbidity (OR = 1.53, 95% CI 1.06-2.22) were significantly associated with increased risk 30-day mortality (C-statistic = 0.82, 95% CI 0.79-0.85). Dementia (OR = 0.61, 95% CI 0.40-0.95) and time to CT scan > 60 min (OR = 0.50, 95% CI 0.34-0.74) were associated with decreased mortality risk. CONCLUSION We identified five factors associated with increased 30-day mortality in older trauma patients: GCS < 15, ISS > 15, age ≥ 85 years, anticoagulation, and multimorbidity. These factors should be considered when developing modified trauma team activation criteria for older adults.

Abstract
BACKGROUND Frailty assessment by paramedics in the prehospital setting is understudied. The goals of this study were to assess the inter-rater reliability and accuracy of frailty assessment by paramedics using the Clinical Frailty Scale (CFS). METHODS This was a cross-sectional study with paramedics exposed to 30 clinical vignettes created from real-life situations. There was no teaching intervention prior to the study and paramedics were only provided with the French version of the CFS (definitions and pictograms). The primary outcome was the inter-rater reliability of the assessment. The secondary outcome was the accuracy, compared with the expert-based assessment. Reliability was determined by calculating an intraclass correlation coefficient (ICC). Accuracy was assessed through a mixed effects logistic regression model. A sensitivity analysis was carried out by considering that an assessment was still accurate if the score differed from no more than 1 level. RESULTS A total of 56 paramedics completed the assessment. The overall assessment was found to have good inter-rater reliability (ICC = 0.87 [95%CI 0.81-0.93]). The overall accuracy was moderate at 60.6% (95%CI 54.9-66.1) when considering the full scale. It was however much higher (94.8% [95%CI 92.0-96.7] when close assessments were considered as accurate. The only factor associated with accurate assessment was field experience. CONCLUSION The assessment of frailty by paramedics was reliable in this vignette-based study. However, the accuracy deserved to be improved. Future research should focus on the clinical impact of these results and on the association of prehospital frailty assessment with patient outcomes. REGISTRATION This study was registered on the Open Science Framework registries ( https://doi.org/10.17605/OSF.IO/VDUZY ).

Abstract
BACKGROUND We developed the Canadian Syncope Pathway (CSP) based on the Canadian Syncope Risk Score (CSRS) to aid emergency department (ED) syncope management. This pilot implementation study assessed patient inclusion, length of transition period, as well as process measures (engagement, reach, adoption, and fidelity) to prepare for multicenter implementation. METHODS A non-randomized stepped wedge trial at two hospitals was conducted over a 7-month period. After 2-3 months in the control condition, the hospitals crossed over in a stepwise fashion to the intervention condition. Study participants were ED and non-ED physicians, or their delegates, and patients (aged ≥ 18 years) with syncope. We aimed to analyze patient characteristics, ED management including disposition decision, and CSRS recommendations application for all eligible patients during the intervention period. Our targets were 95% inclusion rate, 70% adoption (proportion of physicians who applied the pathway), 60% reach (intervention applied to eligible patients) and 70% fidelity (appropriate recommendations application) for all eligible patients. Clinical Trials registration NCT04790058. RESULTS 1002 eligible patients (mean age 56.6 years; 51.0% males) were included: 349 patients during the control and 653 patients during the intervention period. Physician engagement varied from 39.7% to 97.1% for presentation at meetings. Process measures for the first month and the end of the intervention were: adoption 70.7% (58/82) and 84.4% (103/122), reach 67.5% (108/160) and 55.0% (359/653), fidelity among patients with physician data form completion 86.3% (88/102) and 88.3% (294/333), versus fidelity among all eligible patients 83.8% (134/160) and 83.3% (544/653) respectively with no significant differences in fidelity at one month and the end of the intervention period. CONCLUSION In this pilot study, we achieved all prespecified benchmarks for proceeding to the multicenter CSP implementation except reach. Our results indicate a 1-month transition period will be adequate though regular reminders will be needed during full-scale implementation.

Abstract
BACKGROUND Acute heart failure is a serious condition commonly seen in the emergency department (ED). The HEARTRISK6 Scale has been recently developed to identify the risk of poor outcomes but has not been tested. We sought to describe the management and outcomes of ED patients with acute heart failure and to evaluate the potential impact of the HEARTRISK6 Scale. METHODS We conducted a health records review of 300 consecutive acute heart failure patients presenting to two tertiary care EDs. Two evaluators abstracted clinical variables, ED management and treatment details, and patient outcomes using the electronic health records platform (EPIC) and attending physicians verified the data. The primary outcome measure was a short-term serious outcome, as shown in Results. In addition, the HEARTRISK6 score was calculated retrospectively. RESULTS We included 300 patients with mean age of 78.5 years, 51.0% male, 56.3% arrival by ambulance, and 67.0% admitted to hospital. 25.3% experienced a short-term serious outcome 1) after admission (N = 201): non-invasive ventilation 14.9%, intubation 1.5%, major cardiac procedure 5.0%, myocardial infarction 2.0%, death 8.5%; 2) after ED discharge (N = 99): return to ED 21.2%, death 4.0%. Those initially admitted experienced a much higher proportion of serious outcomes compared to those discharged (29.9% vs. 16.2%). A HEARTRISK6 Scale cut-point score of ≥ 1 would have had a sensitivity of 91.0%, specificity 24.5%, and negative likelihood ratio 0.37 for short-term serious outcomes and suggested hospital admission for 80.7% of cases. CONCLUSION There was a large range of severity of illness of acute heart failure patients and a wide variety of treatments were administered in the ED. Both admitted and discharged patients experienced a high proportion of poor outcomes. The HEARTRISK6 Scale showed a high sensitivity for short-term serious outcomes but with the potential to increase hospital admissions. Further validation of the HEARTRISK6 Scale is required before routine clinical use.

Am J Emerg Med 2023; 70:10-18. [PMID: 37186978 DOI: 10.1016/j.ajem.2023.04.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 04/12/2023] [Accepted: 04/17/2023] [Indexed: 05/17/2023] Open
Abstract
BACKGROUND Pain is commonly encountered in the Emergency Department (ED) and pre-hospital setting and often requires opioid analgesia. We sought to synthesize the available evidence on the effectiveness of sufentanil for acute pain relief for adult patients in the pre-hospital or ED setting. METHODS This systematic review was conducted in accordance with PRISMA guidelines. Medline, Embase, Cochrane CENTRAL, and CINAHL were searched from inception to February 1, 2022. The grey literature was also searched. We included randomized controlled trials of adult patients with acute pain who were treated with sufentanil. Two reviewers independently completed screening, full text review, and data extraction. Primary outcome was reduction in pain. Secondary outcomes included adverse events, need for rescue analgesia, and patient and provider satisfaction. Risk of bias was assessed using the Cochrane Risk of Bias 2 tool. A meta-analysis was not performed due to heterogeneity. RESULTS Of 1120 unique citations, four studies (3 ED and 1 pre-hospital) met full inclusion criteria (n = 467 participants). The overall quality of the included studies was high. Intranasal (IN) sufentanil was superior to placebo for pain relief at 30 min (difference 20.8%, 95% CI 4.0-36.2%, p = 0.01). Both IN (two studies) and IV sufentanil (one study) were comparable to IV morphine. Mild adverse events were common and there was a higher propensity for minor sedation in patients receiving sufentanil. There were no serious adverse events requiring advanced interventions. CONCLUSION Sufentanil was comparable to IV morphine and was superior to placebo for rapid relief of acute pain in the ED setting. The safety profile of sufentanil is similar to IV morphine in this setting, with minimal concern for serious adverse events. The intranasal formulation may provide an alternative, rapid, non-parenteral route that could benefit our unique emergency department and pre-hospital patient population. Due to the overall small sample size of this review, larger studies are required to confirm safety.

Abstract
Background For patients with atrial fibrillation seen in the emergency department (ED) following a transient ischemic attack (TIA) or minor stroke, the impact of initiating oral anticoagulation immediately rather than deferring the decision to outpatient follow-up is unknown. Methods and Results We conducted a planned secondary data analysis of a prospective cohort of 11 507 adults in 13 Canadian EDs between 2006 and 2018. Patients were eligible if they were aged 18 years or older, with a final diagnosis of TIA or minor stroke with previously documented or newly diagnosed atrial fibrillation. The primary outcome was subsequent stroke, recurrent TIA, or all-cause mortality within 90 days of the index TIA diagnosis. Secondary outcomes included stroke, recurrent TIA, or death and rates of major bleeding. Of 11 507 subjects with TIA/minor stroke, atrial fibrillation was identified in 11.2% (1286, mean age, 77.3 [SD 11.1] years, 52.4% male). Over half (699; 54.4%) were already taking anticoagulation, 89 (6.9%) were newly prescribed anticoagulation in the ED. By 90 days, 4.0% of the atrial fibrillation cohort had experienced a subsequent stroke, 6.5% subsequent TIA, and 2.6% died. Results of a multivariable logistic regression indicate no association between prescribed anticoagulation in the ED and these 90-day outcomes (composite odds ratio, 1.37 [95% CI, 0.74-2.52]). Major bleeding was found in 5 patients, none of whom were in the ED-initiated anticoagulation group. Conclusions Initiating oral anticoagulation in the ED following new TIA was not associated with lower recurrence rates of neurovascular events or all-cause mortality in patients with atrial fibrillation.

Abstract
OBJECTIVES To evaluate the agreement between three emergency department (ED) vulnerability screeners, including the InterRAI ED Screener, ER2, and PRISMA-7. Our secondary objective was to evaluate the discriminative accuracy of screeners in predicting discharge home and extended ED lengths-of-stay (> 24 h). METHODS We conducted a nested sub-group study using data from a prospective multi-site cohort study evaluating frailty in older ED patients presenting to four Quebec hospitals. Research nurses assessed patients consecutively with the three screeners. We employed Cohen's Kappa to determine agreement, with high-risk cut-offs of three and four for the PRISMA-7, six for the ER2, and five for the interRAI ED Screener. We used logistic regression to evaluate the discriminative accuracy of instruments, testing them in their dichotomous, full, and adjusted forms (adjusting for age, sex, and hospital academic status). RESULTS We evaluated 1855 older ED patients across the four hospital sites. The mean age of our sample was 84 years. Agreement between the interRAI ED Screener and the ER2 was fair (K = 0.37; 95% CI 0.33-0.40); agreement between the PRISMA-7 and ER2 was also fair (K = 0.39; 95% CI = 0.36-0.43). Agreement between interRAI ED Screener and PRISMA-7 was poor (K = 0.19; 95% CI 0.16-0.22). Using a cut-off of four for PRISMA-7 improved agreement with the ER2 (K = 0.55; 95% CI 0.51-0.59) and the ED Screener (K = 0.32; 95% CI 0.2-0.36). When predicting discharge home, the concordance statistics among models were similar in their dichotomous (c = 0.57-0.61), full (c = 0.61-0.64), and adjusted forms (c = 0.63-0.65), and poor for all models when predicting extended length-of-stay. CONCLUSION ED vulnerability scores from the three instruments had a fair agreement and were associated with important patient outcomes. The interRAI ED Screener best identifies older ED patients at greatest risk, while the PRISMA-7 and ER2 are more sensitive instruments.

Abstract
BACKGROUND Adults ≥ 65 are at risk of cervical spine (C-spine) injury, even after low-level falls. The objectives of this systematic review were to determine the prevalence of C-spine injury in this population and explore the association of unreliable clinical exam with C-spine injury. METHODS We conducted this systematic review according to PRISMA guidelines. We searched MEDLINE, PubMed, EMBASE, Scopus, Web of Science, and the Cochrane Database of Systematic reviews to include studies reporting on C-spine injury in adults ≥ 65 years after low-level falls. Two reviewers independently screened articles, abstracted data, and assessed bias. Discrepancies were resolved by a third reviewer. A meta-analysis was performed to estimate overall prevalence and the pooled odds ratio for the association between C-spine injury and an unreliable clinical exam. RESULTS The search identified 2044citations, 138 full texts were screened, and 21 studies were included in the systematic review. C-spine injury prevalence in adults ≥ 65 years after low-level falls was 3.8% (95% CI: 2.8-5.3). The odds of c-spine injury in those with altered level of consciousness (aLOC) v/s not aLOC was 1.21 (0.90-1.63) and in those with GCS < 15 v/s GCS 15 was 1.62 (0.37-6.98). Studies were at a low-risk of bias, although some had low recruitment and significant loss to follow-up. CONCLUSIONS Adults ≥ 65 years are at risk of cervical spine injury after low-level falls. More research is needed to determine whether there is an association between cervical spine injury and GCS < 15 or altered level of consciousness.

Abstract
Objectives We set out to determine the accuracy of the interRAI Emergency Department (ED) Screener in predicting the need for detailed geriatric assessment in the ED. Our secondary objective was to determine the discriminative ability of the interRAI ED Screener for predicting the odds of discharge home and extended ED length of stay (>24 hours). Methods We conducted a multiprovince prospective cohort study in Canada. The need for detailed geriatric assessment was determined using the interRAI ED Screener and the interRAI ED Contact Assessment as the reference standard. A score of ≥5 was used to classify high-risk patients. Assessments were conducted by emergency and research nurses. We calculated the sensitivity, positive predictive value, and false discovery rate of the interRAI ED Screener. We employed logistic regression to predict ED outcomes while adjusting for age, sex, academic status, and the province of care. Results A total of 5629 older ED patients across 11 ED sites were evaluated using the interRAI ED Screener and 1061 were evaluated with the interRAI ED Contact Assessment. Approximately one-third of patients were discharged home or experienced an extended ED length of stay. The interRAI ED Screener had a sensitivity of 93%, a positive predictive value of 82%, and a false discovery rate of 18%. The interRAI ED Screener predicted discharge home and extended ED length of stay with fair accuracy. Conclusion The interRAI ED Screener is able to accurately and rapidly identify individuals with medical complexity. The interRAI ED Screener predicts patient-important health outcomes in older ED patients, highlighting its value for vulnerability screening.

Abstract
BACKGROUND Up to 3% of all Emergency Department (ED) visits are due to skin and soft tissue infections such as non-purulent cellulitis. The current treatment failure rate is approximately 20%. Evidence is lacking regarding the optimal outpatient management of cellulitis. OBJECTIVES To evaluate the feasibility of a randomized trial comparing high-dose (1000 mg) to standard-dose (500 mg) cephalexin to treat ED patients with cellulitis. METHODS A parallel arm double-blind randomized controlled pilot trial conducted at two EDs in Canada. Eligible participants were adults (age ≥ 18 years) presenting to the ED with non-purulent cellulitis and determined by the treating emergency physician to be eligible for outpatient management with oral antibiotics. Participants were randomized to high-dose or standard-dose cephalexin four times daily for 7 days. The primary feasibility outcome was participant recruitment rate (target ≥ 35%). The preliminary primary effectiveness outcome was oral antibiotic treatment failure. RESULTS Of 134 eligible participants approached for trial participation, 69 (51.5%, 95% CI 43.1 to 59.8%) were recruited and randomized. After excluding three randomized participants due to an alternate diagnosis, 33 participants were included in each arm. Nineteen eligible cases (14.2%) were missed. Loss to follow-up was 6.1%. Treatment failure occurred in four patients (12.9%) in the standard-dose arm versus one patient (3.2%) in the high-dose arm. A greater proportion had minor adverse events in the high-dose arm. No patients had an unplanned hospitalization within 14 days. CONCLUSION This pilot randomized controlled trial comparing high-dose to standard-dose cephalexin for ED patients with cellulitis demonstrated a high participant recruitment rate and that a full-scale trial is feasible. High-dose cephalexin had fewer treatment failures but with a higher proportion of minor adverse effects. The findings of this pilot will be used to inform the design of a future large trial. TRIAL REGISTRATION This trial was registered at ClinicalTrials.gov (NCT04471246).
