Emergency physician gender and head computed tomography orders for older adults who have fallen.

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.

Derivation of the Falls Decision Rule to exclude intracranial bleeding without head CT in older adults who have fallen.

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.

History, ECG, Risk Factors (HER) Scoring for Cardiac Risk Stratification in Patients <45 Years of Age Presenting With Chest Pain.

Background Chest pain is a common chief complaint of patients presenting to the emergency department. Acute coronary syndrome (ACS) is found to be the etiology of this symptom in a minority of these patient encounters. This study aimed to determine the utility of using the History, ECG, Risk Factors (HER) components of the History, ECG, Age, Risk Factors, Troponin (HEART) score in ruling out 30-day Major Adverse Cardiac Event (MACE), ACS, ventricular tachycardia, and ventricular fibrillation in patients aged less than 45. Additionally, the utility of this score in ruling out a positive troponin was investigated as well. Methodology This is a retrospective chart review study that examined a consecutive cohort of 7,724 patients presenting with chest pain to the 11 emergency departments of a single healthcare system over a two-year period (January 2019 to December 2020). HER scores of 0 to 1 were categorized as negative (-) and scores of two or greater were categorized as positive (+). Sensitivity, specificity, and predictive values were calculated for the relationship between HER score positivity and primary cardiac disease and troponin results. Results Test characteristics of HER scoring for significant primary cardiac disease in patients between 18 and 45 years of age presenting with undifferentiated chest pain were sensitivity of 88.0 (CI = 80.0-94.0), specificity of 72.6 (CI = 71.8-73.8), positive predictive value of 3.1 (CI = 2.4-3.9), and negative predictive value of 99.8 (CI = 99.7-99.9). Furthermore, an HER score >1 was neither sensitive nor specific in predicting a positive troponin (sensitivity = 80, CI = 71.9-86; specificity = 71.3, CI = 70.3-72.3). However, the negative predictive value of an HER score of 0-1 was 99.5 (CI = 99.3-99.7) and the positive predictive value was 4.7 (CI = 3.9-5.7). Conclusions According to this study, when evaluating young patients who are deemed to have a subjectively non-highly suspicious history, who have minimal risk factors, and who have an ECG without significant ST deviation, troponin testing is low yield in the risk stratification of patients under the age of 45 for serious primary cardiac disease.

Compassion Fatigue and Satisfaction among Turkish Emergency Medicine Residents Using the Professional Quality of Life Scale.

Introduction: Emergency medicine (EM) residents are at high risk for burnout syndrome. The professional quality of life scale (ProQOL) is a validated survey that measures compassion satisfaction (CS) and compassion fatigue, which is comprised of burnout and secondary traumatic stress (STS) scales. This study sought to evaluate CS and fatigue among Turkish EM residents using the ProQOL survey. Methods: This was a cross-sectional study of Turkish EM residents who are part of the EM Residency Association of Turkey. The ProQOL survey version 5 was E-mailed in Turkish to all 150 EM residents. Participants were currently employed as EM residents. Demographics and satisfaction with quality of life were also collected. Results: Eighty residents completed the survey. Almost half of the respondents were either very dissatisfied or dissatisfied with their overall quality of life. Turkish EM residents not only had moderate levels of CS (scoring 33.9 ± 7.9), but also suffered moderate burnout (27.0 ± 5.9) and STS (24.7 ± 5.3). Conclusions: Turkish EM residents have moderate levels of CS and moderate levels of burnout and secondary traumatic stress.

Reverse Takotsubo Cardiomyopathy After Accidental Exposure to an Illicit Substance: A Case Report.

Stress-induced (Takotsubo) cardiomyopathy is a clinical syndrome and its incidence has been on the rise. Patients with this syndrome often present with chest pain, dyspnea, or syncope. The findings from a typical cardiac evaluation can make this entity difficult to distinguish from acute myocardial infarction (AMI). A 50-year-old woman presented to the emergency department (ED) with anxiety and palpitations after the accidental ingestion of a sympathomimetic. The patient had consumed coffee that she had brewed in a hotel coffee pot, unaware that a previous guest had placed drug paraphernalia including methamphetamine in the water reservoir of the coffee pot. Her symptoms had started shortly thereafter. In the ED, the patient's workup was remarkable for positive troponin and an echocardiogram demonstrating basilar hypokinesis. The patient's ejection fraction was reduced at 40%. She was admitted to the hospital, where she underwent catheterization, demonstrating normal coronary arteries. She had full clinical recovery at the six-month follow-up. Reverse Takotsubo cardiomyopathy is a rare variant of Takotsubo cardiomyopathy, which presents with basal left ventricular hypokinesis. It is associated with younger age and female gender and has an overall good prognosis. This diagnosis should be considered in patients who are otherwise at low risk for atherosclerotic cardiac disease with known emotional or physical triggers and changes in left ventricular function. Treatment is generally supportive, but a Takotsubo cardiomyopathy diagnosis alters the management of shock and dysrhythmia when known.

Gender coding in job advertisements for academic, non-academic, and leadership positions in emergency medicine.

OBJECTIVES: Gender disparities continue to exist in emergency medicine (EM) despite increasing percentages of women in medical school and residencies. Prior studies in other male dominated industries have shown using masculine or feminine-coded language in job advertisements affects the proportion of male versus female applicants who choose to apply for those jobs. The goal of this study was to determine if gender-coding exists in EM job advertisements, and to see if there were differences between academic vs. non-academic jobs or administrative vs. non-administrative jobs. METHODS: This was a cross sectional study of EM jobs advertised in the United States on 13 academic and non-academic medical job databases from September 2020-February 2021. Using a gender decoder program based on prior research by Gaucher et al. on gendered wording in job advertisements, we analyzed each job to determine if the job advertisement was overall highly masculine, masculine, highly feminine, feminine, or neutral. Each job was categorized as academic, non-academic, administrative, or non-administrative. Data were analyzed using descriptive statistics and chi-square analysis. RESULTS: Seventy-four EM job advertisements were posted during the study period. Forty-four (59.4%) of these coded out as masculine or strongly masculine, 18 (24.3%) coded out as feminine or strongly feminine, and 12 (16.2%) were neutral. Only one job advertisement contained no gender-coded words. There were no differences in the gender-coding of academic, non-academic, or administrative jobs. CONCLUSION: Job advertisements for EM physicians tend to contain more masculine-coded language. Almost all job advertisements for emergency medicine physicians in this study contained at least one gender-coded word. Further studies could explore whether changing the language of job advertisements in EM has an impact on the proportion of women who choose to apply to EM jobs.

Patients' sex and race are independent predictors of HEART score documentation by emergency medicine providers.

INTRODUCTION: The HEART score is a widely used clinical decision tool that provides emergency providers with objective risk stratification for patients presenting to the emergency department (ED) with undifferentiated chest pain (CP). There is no data as to which patients undergo formal risk stratification with a HEART score, and whether patient demographics influence decisions to apply the HEART score. Our objective was to determine if sex or race independently predict documentation of patients' HEART scores in CP patients. METHODS: This is a retrospective cohort study of all patients with a chief complaint of CP who presented to EDs within a single health care system (11 EDs) from September 2018-January 2021. Charts were identified via query of the electronic medical record, and patient age, race, and sex were extracted. The presence or absence of documentation of a HEART score was also recorded. Patient race was categorized as white/non-white. Sex was categorized as male/female. Age was inputted as a continuous variable. We performed logistic regression to determine which variables were associated with documentation of a HEART score. RESULTS: 38,277 patients were included in the study. The median patient age was 51 with IQR 36-64, and 18,927 (47.5%) were male. HEART scores were documented in 24,181. Younger age, female sex, and non-white race were all independent predictors of not having HEART score risk stratification documented in the medical record. CONCLUSIONS: Women and non-white patients are less likely to receive HEART score risk stratification when presenting with undifferentiated CP, even when controlling for patient age. Further studies should address whether this influences patient centered outcomes.

Which older emergency patients are at risk of intracranial bleeding after a fall? A protocol to derive a clinical decision rule for the emergency department.

INTRODUCTION: Falling on level ground is now the most common cause of traumatic intracranial bleeding worldwide. Older adults frequently present to the emergency department (ED) after falling. It can be challenging for clinicians to determine who requires brain imaging to rule out traumatic intracranial bleeding, and often head injury decision rules do not apply to older adults who fall. The goal of our study is to derive a clinical decision rule, which will identify older adults who present to the ED after a fall who do not have clinically important intracranial bleeding. METHODS AND ANALYSIS: This is a prospective cohort study enrolling patients aged 65 years or older, who present to the ED of 11 hospitals in Canada and the USA within 48 hours of having a fall. Patients are included if they fall on level ground, off a chair, toilet seat or out of bed. The primary outcome is the diagnosis of clinically important intracranial bleeding within 42 days of the index ED visit. An independent adjudication committee will determine the primary outcome, blinded to all other data. We are collecting data on 17 potential predictor variables. The treating physician completes a study data form at the time of initial assessment, prior to brain imaging. Data extraction is supplemented by an independent, structured electronic medical record review. We will perform binary recursive partitioning using Classification and Regression Trees to derive a clinical decision rule. ETHICS AND DISSEMINATION: The study was initially approved by the Hamilton Integrated Research Ethics Committee and subsequently approved by the research ethics boards governing all participating sites. We will disseminate our results by journal publication, presentation at international meetings and social media. TRIAL REGISTRATION NUMBER: NCT03745755.

Failure Rates During Reuse of Disposable N95 Masks in Clinical Practice in the Emergency Department.

INTRODUCTION: The coronavirus 2019 pandemic caused a shortage of disposable N95 respirators, prompting healthcare entities to extend the use of these masks beyond their intended single-use manufacturer recommendation with a paucity of supporting research. METHODS: We performed a prospective cohort study of ED healthcare workers (HCW) ("subjects") required to use respirators at an academic, Level I trauma center. Subjects had been previously fit tested and assigned an appropriately sized N95 mask per hospital protocol. Per study protocol, subjects were fit tested periodically throughout their shifts and on multiple shifts over the eight-week study period. Data points collected included the age of the mask, subjective assessment of mask seal quality, and fit test results. We analyzed the data using Fisher's exact test, and calculated odds ratios (OR) to determine the failure rate of disposable N95 masks following reuse. RESULTS: A total of 130 HCWs underwent fit testing and 127 were included for analysis. Mask failure rate climbed after day 2 of use, with 33.3% of masks failing at day 3, 42.9% at day 4, and 50% at ≥ day 5. Categorizing the masks into those being used for two or fewer days vs those in use for three or more, failure was more common on day 3 of use or older compared to those in the first two days of use (41.8% vs 8.3%, P < 0.0001) with an OR of failure with an older mask of 7.9 (confidence interval [CI], 2.8-22.3). The healthcare workers' assessment of poor seal was 33.3% sensitive (CI, 18.6-51.9) and 95.7% specific (CI, 88.8-98.6) for fit test failure. CONCLUSION: Disposable N95 masks have significant failure rates following reuse in clinical practice. Healthcare personnel also performed poorly in assessing the integrity of the seal of their disposable respirators.

The pragmatic use of industrial elastomeric facemasks in health care practice during the COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic has forced health care workers to explore alternative personal protective equipment (PPE) strategies due to traditional product shortages in the setting of increased global demand. Some physicians have chosen to use elastomeric face masks (EFMs), traditionally used in non-healthcare industries. METHODS: We performed a prospective cohort study of Emergency Medicine (EM) physicians working at a Level 1 Trauma Center who chose to use self-supplied EFMs for PPE. All subjects used commercial EFMs with disposable filters (N95, P95, or P100). All subjects chose their mask size independently with no input from employee health regarding appropriate fit. Per study protocol, subjects were fit tested periodically during clinical shifts over the course of the 6-week study period. All investigators performing fit testing underwent OSHA qualitative fit testing training. Data collected included mask/filters age, subjective assessment of mask seal quality, and fit test results. The data were analyzed using descriptive statistics. RESULTS: 105 fit tests were performed on physicians wearing EFMs over the course of 49 shifts. Physicians felt their fit was adequate for all tests performed. There were no fit test failures in any subjects. CONCLUSIONS: EFMs have an extremely low failure rate. Physicians are able to assess the adequacy of fit and accurately choose EFM size.

The efficacy of continuous use disposable N95 masks in clinical practice in the emergency department.

During the SARS-CoV-2 pandemic, many emergency departments (EDs) initiated continuous use of N95 disposable respirators (N95s) rather than discarding them after each use to conserve respirators. This study investigates the efficacy of wearing disposable N95s continuously during clinical work. METHODS: This is a prospective cohort study of ED staff required to wear N95s continuously throughout their shifts. Subjects were doctors, nurses, and technicians who were previously fitted for their assigned N95 by employee health. Subjects were fit tested periodically throughout their shifts. Investigators filled out a questionnaire for each subject noting the hours of continuous N95 wear. Data were analyzed using descriptive statistics. RESULTS: One hundred thirteen N95s were evaluated, with 23 failures at first testing. These were not retested. Twenty-seven N95s passed at the start of a shift and did not have repeat testing during the course of the shift. These were excluded from further analysis. Seventeen N95s passed testing after several hours of continuous wear, but only had a single fit test done partway or at the end of a shift. These were assumed to have passed if tested at shift start, and were assigned as "passes" for continuous use. Forty-six N95s had an initial pass and were evaluated for continuous use, of which 6 subsequently failed later in the shift, giving a fail rate with continuous use of 9.5%. CONCLUSION: Continuous use of disposable N95s throughout an ED shift is reasonable during a PPE shortage if wearers are assured of fit at the start of their shift.

Prehospital end-tidal CO2 as an early marker for transfusion requirement in trauma patients.

OBJECTIVE: Below normal end-tidal carbon dioxide measurement (ETCO2) is associated with worse outcomes in sepsis and trauma patients as compared to patients with normal ETCO2. We sought to determine if ETCO2 can be used in the prehospital setting to predict transfusion requirement, operative hemorrhage control, or mortality in the first 24 h after admission for trauma. METHODS: This is a retrospective cohort study at a suburban, academic Level 1 Trauma Center. Patients were sequentially identified as prehospital trauma alerts from a single EMS system which requires, per policy, ETCO2 for all traumas. One year of prehospital data was collected and paired with hospital trauma registry data. Comparisons were made between ETCO2 values for patients who required transfusion, operative blood loss control, or who died, and those who did not. RESULTS: Two hundred thirty-five trauma patients were transported via the study EMS system, of which 105 (44.7%) had documented ETCO2 values. Patient mean age was 60 (SD24) years with 59 (56.2%) male. Three patients were intubated prehospital and seven were intubated in the trauma bay. Mean prehospital ETCO2 for those who needed transfusion, surgery, or died (n = 11) was 25.7 (9.1) compared to 30.6 (7.8) for those who did not (p = 0.049). Optimal cutoff for our population was EtCO2 ≤ 27 with a sensitivity of 72.7% (95% CI 32-93) and specificity of 72.2% (62-81). CONCLUSION: Below normal ETCO2 values were associated with increase need for transfusion, operative intervention, and death. Further study is warranted to determine if ETCO2 outperforms other predictors of severe trauma.

The 2019-2020 Novel Coronavirus (Severe Acute Respiratory Syndrome Coronavirus 2) Pandemic: A Joint American College of Academic International Medicine-World Academic Council of Emergency Medicine Multidisciplinary COVID-19 Working Group Consensus Paper.

What started as a cluster of patients with a mysterious respiratory illness in Wuhan, China, in December 2019, was later determined to be coronavirus disease 2019 (COVID-19). The pathogen severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel Betacoronavirus, was subsequently isolated as the causative agent. SARS-CoV-2 is transmitted by respiratory droplets and fomites and presents clinically with fever, fatigue, myalgias, conjunctivitis, anosmia, dysgeusia, sore throat, nasal congestion, cough, dyspnea, nausea, vomiting, and/or diarrhea. In most critical cases, symptoms can escalate into acute respiratory distress syndrome accompanied by a runaway inflammatory cytokine response and multiorgan failure. As of this article's publication date, COVID-19 has spread to approximately 200 countries and territories, with over 4.3 million infections and more than 290,000 deaths as it has escalated into a global pandemic. Public health concerns mount as the situation evolves with an increasing number of infection hotspots around the globe. New information about the virus is emerging just as rapidly. This has led to the prompt development of clinical patient risk stratification tools to aid in determining the need for testing, isolation, monitoring, ventilator support, and disposition. COVID-19 spread is rapid, including imported cases in travelers, cases among close contacts of known infected individuals, and community-acquired cases without a readily identifiable source of infection. Critical shortages of personal protective equipment and ventilators are compounding the stress on overburdened healthcare systems. The continued challenges of social distancing, containment, isolation, and surge capacity in already stressed hospitals, clinics, and emergency departments have led to a swell in technologically-assisted care delivery strategies, such as telemedicine and web-based triage. As the race to develop an effective vaccine intensifies, several clinical trials of antivirals and immune modulators are underway, though no reliable COVID-19-specific therapeutics (inclusive of some potentially effective single and multi-drug regimens) have been identified as of yet. With many nations and regions declaring a state of emergency, unprecedented quarantine, social distancing, and border closing efforts are underway. Implementation of social and physical isolation measures has caused sudden and profound economic hardship, with marked decreases in global trade and local small business activity alike, and full ramifications likely yet to be felt. Current state-of-science, mitigation strategies, possible therapies, ethical considerations for healthcare workers and policymakers, as well as lessons learned for this evolving global threat and the eventual return to a "new normal" are discussed in this article.

Traumatic cervical fusion hardware displacement presenting with dysphagia and dysphonia.

Surgery for degenerative cervical myelopathy has been increasing in incidence. Almost 20% of patients have complications related to their surgery, although hardware extrusion is rare and generally reported in the first post-operative month. We report the case of a woman with new dysphagia and hoarseness secondary to traumatic screw dislodgement into her pre-vertebral space 5 months after cervical discectomy.

History and physical exam predictors of intracranial injury in the elderly fall patient: A prospective multicenter study.

OBJECTIVES: A prior single-center study demonstrated historical and exam features predicting intracranial injury (ICI) in geriatric patients with low-risk falls. We sought to prospectively validate these findings in a multicenter population. METHODS: This is a prospective observational study of patients ≥65 years presenting after a fall to three EDs. Patients were eligible if they were at baseline mental status and were not triaged to the trauma bay. Fall mechanism, head strike history, headache, loss of consciousness (LOC), anticoagulants/antiplatelet use, dementia, and signs of head trauma were recorded. Radiographic imaging was obtained at the discretion of treating physicians. Patients were called at 30 days to determine outcome in non-imaged patients. RESULTS: 723 patients (median age 83, interquartile range 74-88) were enrolled. Although all patients were at baseline mental status, 76 had GCS <15, and 154 had dementia. 406 patients were on anticoagulation/antiplatelet agents. Fifty-two (7.31%) patients had traumatic ICI. Two study variables were helpful in predicting ICI: LOC (odds ratio (OR) 2.02) and signs of head trauma (OR 2.6). The sensitivity of these items was 86.5% (CI 73.6-94) with a specificity of 38.8% (CI 35.1-42.7). The positive predictive value in this population was 10% (CI 7.5-13.3) with a negative predictive value of 97.3% (CI 94.4-98.8). Had these items been applied as a decision rule, 273 patients would not have undergone CT scanning, but 7 injuries would have been missed. CONCLUSION: In low-risk geriatric fall patients, the best predictors of ICI were physical findings of head trauma and history of LOC.

Iatrogenic Splenic Laceration Presenting as Syncope.

Millions of colonoscopies are performed annually for routine health maintenance in the United States. Patients commonly have adverse events from colonoscopy preparation, anesthesia, and procedural complications. We report a case of syncope secondary to iatrogenic splenic laceration from colonoscopy.

An observational study of patients' attitudes to tattoos and piercings on their physicians: the ART study.

INTRODUCTION: Perceptions regarding body art change over time as societal norms change. Previous research regarding patients' perceptions of physicians with exposed body art have been hampered by flaws in design methodology that incorporate biases into patient responses. This study was performed to determine whether emergency department (ED) patients perceived a difference in physician competence, professionalism, caring, approachability, trustworthiness and reliability in the setting of exposed body art. METHODS: Standardised surveys about physician competence, professionalism, caring, approachability, trustworthiness and reliability rating providers on a five point Likert scale were administered to patients in an ED after an encounter with a physician provider who demonstrated no body art modification, non-traditional piercings, tattoos, or both piercings and tattoos. Each provider served as their own control. Patients were blinded to the purpose of the survey. RESULTS: Patients did not perceive a difference in physician competence, professionalism, caring, approachability, trustworthiness or reliability in the setting of exposed body art. Patients assigned top box performance in all domains >75% of the time, regardless of physician appearance. CONCLUSION: In the clinical setting, having exposed body art does not significantly change patients' perception of the physician.
