Early validity and reliability evidence for the American Board of Emergency Medicine Virtual Oral Examination.

Background: The American Board of Emergency Medicine (ABEM) in-person Oral Certification Examination (OCE) was halted abruptly in 2020 due to the COVID-19 pandemic. The OCE was reconfigured to be administered in a virtual environment starting in December 2020. Objectives: The purpose of this investigation was to determine whether there was sufficient validity and reliability evidence to support the continued use of the ABEM virtual Oral Examination (VOE) for certification decisions. Methods: This retrospective, descriptive study used multiple data sources to provide validity evidence and reliability data. Validity evidence focused on test content, response processes, internal structure (e.g., internal consistency and item response theory), and the consequences of testing. A multifaceted Rasch reliability coefficient was used to measure reliability. Study data were from two 2019 in-person OCEs and the first four VOE administrations. Results: There were 2279 physicians who took the 2019 in-person OCE examination and 2153 physicians who took the VOE during the study period. Among the OCE group, 92.0% agreed or strongly agreed that the cases on the examination were cases that an emergency physician should be expected to see; 91.1% of the VOE group agreed or strongly agreed. A similar pattern of responses given to a question about whether the cases on the examination were cases that they had seen. Additional evidence of validity was obtained by the use of the EM Model, the process for case development, the use of think-aloud protocols, and similar test performance patterns (e.g., pass rates). For reliability, the Rasch reliability coefficients for the OCE and the VOE during the study period were all >0.90. Conclusions: There was substantial validity evidence and reliability to support ongoing use of the ABEM VOE to make confident and defensible certification decisions.

Emergency physician and nurse discretion accurately triage high-risk trauma patients.

PURPOSE: Prehospital trauma team activation (TTA) criteria allow for early identification of severely injured trauma patients. Although most TTA criteria are objective, one TTA criterion is subjective: emergency provider discretion. The study objective was to define the ability of emergency department physician and nurse discretion to accurately perform prehospital triage of high risk trauma patients. METHODS: All highest level TTAs arriving to our American College of Surgeons (ACS)-verified Level 1 trauma center (06/2015-08/2020) were included. Exclusions were undocumented prehospital vitals or discharge disposition. At our institution, TTAs are triggered for standard ACS TTA criteria and age > 70 with traumatic mechanism other than ground level fall. Patients meeting ≥ 1 criterion apart from "Emergency Provider Discretion" were defined as Standard TTAs and patients meeting only "Emergency Provider Discretion" were defined as Discretion TTAs. Univariable/multivariable analyses compared injury data and outcomes. RESULTS: 4540 patients met inclusion/exclusion criteria: 3330 (73%) Standard TTAs and 1210 (27%) Discretion TTAs. Discretion TTAs were younger (34 vs. 37 years, p < 0.001) and more frequently injured by penetrating trauma (38% vs. 33%, p = 0.008), particularly stab wounds (64% vs. 29%). Overtriage rates were comparable after Discretion vs. Standard TTAs (33% vs. 31%, p = 0.141). Blood transfusion < 4 h (31% vs. 32%, p = 0.503) and ICU admission ≥ 3 days (25% vs. 27%, p = 0.058) were comparable between groups. Discretion TTA was independently associated with increased need for emergent surgery (OR 1.316, p = 0.005). CONCLUSIONS: Emergency provider discretion accurately identifies major trauma, with comparable rates of overtriage as standard TTA criteria. Discretion TTAs were as likely as Standard TTAs to require early blood transfusion and prolonged ICU stay. After controlling for confounders, Discretion TTAs were significantly more likely to require emergent surgical intervention. Emergency provider discretion should be recognized as a valid method of identifying major trauma patients at high risk of need for intervention.

Misdiagnosis of Orbital Foreign Body as Glaucoma Drainage Device.

BACKGROUND: Sight-threatening complications from retained orbital and intraocular foreign bodies are frequently reported in literature. Delays in diagnosis can result in severe complications, including choroidal neovascularization, infection, and irreversible vision loss. Therefore, it is imperative that emergency physicians consider the possibility of orbital and intraocular foreign bodies when evaluating patients with acute facial trauma. CASE REPORT: A 91-year-old woman with a history of laser-treated glaucoma and cataracts presented to an outside emergency department after a ground-level fall. A maxillofacial noncontrast computed tomography scan showed no facial fractures or hemorrhage, but a 41 mm × 4 mm foreign body within the intraconal compartment of the right orbit was identified. The object was presumed to be an implanted glaucoma drainage device, and the patient was discharged without antibiotics. One day after discharge, the patient developed right periorbital swelling and erythema with increasing purulent discharge and skin thickening, ultimately requiring transfer to our facility for management of complex right orbital cellulitis, orbital compartment syndrome, and surgical foreign body removal. Despite globe exploration and surgical intervention, the patient developed a frozen globe with no light perception in the right eye. Why Should an Emergency Physician Be Aware of This? Subtle ophthalmologic emergencies such as sight-threatening foreign bodies can be challenging to diagnose on imaging, particularly with the advent of implantable ocular technology. When an orbital foreign body is discovered in the context of facial trauma, early ophthalmology consultation should be considered.

Costs and Benefits of Initial Certification for Emergency Medicine Residency Graduates.

BACKGROUND: Graduates of emergency medicine residency programs can seek certification from the American Board of Emergency Medicine (ABEM), yet the costs and perceived value by residents is not clear. OBJECTIVE: This report sought to better define the value of board certification by asking physicians taking the ABEM Oral Certification Examination (OCE) to describe its costs (eg, time, money) and perceived benefits. METHODS: A descriptive, cross-sectional, voluntary, anonymous survey was administered to physicians taking the 2018 spring and fall ABEM OCEs. Response frequencies were used to report response rates. RESULTS: There were 2016 physicians who participated in the 2018 OCEs, of whom 1565 (78%) completed a survey. With respect to preparation, 38% (599 of 1565 responses) spent more than 30 hours preparing for the examination. Regarding the expense of preparing for the examination, 21% (328) spent nothing, 50% (776) spent less than $1,000, and 2% (38) spent more than $3,000. Most physicians (80%, 1254) reported a learning benefit to preparing for and taking the OCE. There were 49% (765) of respondents who reported that preparing for the examination reinforced their knowledge of emergency medicine; 20% (311) reported no learning benefit. Most physicians (92%, 1442) reported that ABEM certification provided a career benefit, the most common of which was more career opportunities (69%, 1076). CONCLUSIONS: Initial certification requires a considerable investment of time and money. Physicians seeking initial ABEM certification found both learning and professional benefits, with the most frequently reported being reinforcement of medical knowledge and more career opportunities.

A Novel Emergency Department-based Community Notification Method for Clinical Research Without Consent.

OBJECTIVE: We used an emergency department (ED)-based method to provide targeted, individualized consultation; community notification; and public disclosure and collect data regarding willingness to participate in prospective resuscitation research requiring waiver of consent. METHODS: We conducted a prospective survey of convenience cohort in an urban ED. We targeted the community of ED patients with pulmonary disease for individualized notification and public disclosure using a 1) large poster, 2) scripted oral presentation describing an emergency intubation clinical trial, and 3) video demonstration. RESULTS: Approximately 10% of our annual ED census, 6,936 subjects, enrolled. Of that total, 29 were also subjects in a prospective coincident endotracheal resuscitation intubation study, which enrolled a total of 262 subjects. ED community notification was provided to 22 of the 29 (75.9%) subjects prior to the visit during which they were intubated (13 agreed to participate, six declined, and three undecided) and seven of the 29 subjects subsequent to enrollment in the intubation study (five agreed to participate and two undecided). Fourteen of the 29 patients who participated in both projects had undergone endotracheal intubation at least once prior to community notification: 10 agreed to participate in the study, two declined, and two were undecided. CONCLUSIONS: Emergency department-based community notification and public disclosure is a viable way to provide information to a target population and collect data about the success of the notification. Feedback data collection is critical to an ethical understanding of the success of community notification for the institutional review board and investigators. Collection of feedback data should be required as a subject protection for exception from informed consent in emergency settings.

The use of inhaled nitrous oxide for analgesia in adult ED patients: a pilot study.

BACKGROUND: Oligoanalgesia challenges emergency department (ED) health care providers and remains an area of patient dissatisfaction. Nitrous oxide (NO) is a safe, quick-acting, and well-tolerated sedative agent with analgesic and anxiolytic properties that make it ideal for ED use. OBJECTIVES: We seek to test the effectiveness of a self-administered and self-contained NO device as an analgesic agent in the ED and assess patient and staff satisfaction with this method. METHODS: We enrolled 85 patients 18 years and older in a prospective observational study of patients presenting to the ED with moderate to severe pain (≥30 mm on a 100-mm visual analog scale). Subjects received a mixture of 50% NO via a self-administered portable delivery device. Primary outcome was the reduction in baseline pain scores at 20, 40, and 60 minutes. Secondary outcomes were patient, nurse, and physician satisfaction as reported on a brief satisfaction questionnaire. RESULTS: There was a significant reduction in mean pain scores from baseline to 20 minutes that was sustained through the 60-minute period. Most subjects (93%; 95% confidence interval [CI], 85%-97%) and nurses (97%; 95% CI, 90%-99%) reported that the NO delivery system was easy to use and were satisfied with the level of pain relief and would use NO in the future (82%; 95% CI, 73%-89%). Physicians and nurses were also satisfied with the analgesic effects of NO (82%; 95% CI, 73%-89%). CONCLUSIONS: The portable NO device is an effective analgesia adjunct for ED patients presenting with painful conditions, and patients, ED nurses, and emergency physicians are satisfied with its use. Nitrous oxide coupled with a nurse-driven analgesia protocol may provide a novel solution for improvement in ED analgesia rates and overall patient satisfaction with ED pain management.

The utility of high-flow oxygen during emergency department procedural sedation and analgesia with propofol: a randomized, controlled trial.

STUDY OBJECTIVE: We determine whether high-flow oxygen reduces the incidence of hypoxia by 20% in adults receiving propofol for emergency department (ED) sedation compared with room air. METHODS: We randomized adults to receive 100% oxygen or compressed air at 15 L/minute by nonrebreather mask for 5 minutes before and during propofol procedural sedation. We administered 1.0 mg/kg of propofol, followed by 0.5 mg/kg boluses until the patient was adequately sedated. Physicians and patients were blinded to the gas used. Hypoxia was defined a priori as an oxygen saturation less than 93%; respiratory depression was defined as an end tidal CO(2) greater than 50 mm Hg, a 10% absolute change from baseline, or loss of waveform. RESULTS: We noted significantly less hypoxia in the 59 patients receiving high-flow oxygen compared with the 58 receiving compressed air (19% versus 41%; P=.007; difference 23%; 95% confidence interval 6% to 38%). Respiratory depression was similar between groups (51% versus 48%; difference 2%; 95% confidence interval -15% to 22%). We observed 2 adverse events in the high-flow group (1 hypotension, 1 bradycardia) and 2 in the compressed air group (1 assisted ventilation, 1 hypotension). CONCLUSION: High-flow oxygen reduces the frequency of hypoxia during ED propofol sedation in adults.

Does end tidal CO2 monitoring during emergency department procedural sedation and analgesia with propofol decrease the incidence of hypoxic events? A randomized, controlled trial.

STUDY OBJECTIVE: We determine whether the use of capnography is associated with a decreased incidence of hypoxic events than standard monitoring alone during emergency department (ED) sedation with propofol. METHODS: Adults underwent ED propofol sedation with standard monitoring (pulse oximetry, cardiac and blood pressure) and capnography and were randomized into a group in which treating physicians had access to the capnography and a blinded group in which they did not. All patients received supplemental oxygen (3 L/minute) and opioids greater than 30 minutes before. Propofol was dosed at 1.0 mg/kg, followed by 0.5 mg/kg as needed. Capnographic and SpO2 data were recorded electronically every 5 seconds. Hypoxia was defined as SpO2 less than 93%; respiratory depression, as end tidal CO2 (ETCO2) greater than 50 mm Hg, ETCO2 change from baseline of 10%, or loss of the waveform. RESULTS: One hundred thirty-two subjects were evaluated and included in the final analysis. We observed hypoxia in 17 of 68 (25%) subjects with capnography and 27 of 64 (42%) with blinded capnography (P=.035; difference 17%; 95% confidence interval 1.3% to 33%). Capnography identified all cases of hypoxia before onset (sensitivity 100%; specificity 64%), with the median time from capnographic evidence of respiratory depression to hypoxia 60 seconds (range 5 to 240 seconds). CONCLUSION: In adults receiving ED propofol sedation, the addition of capnography to standard monitoring reduced hypoxia and provided advance warning for all hypoxic events.

T2-3 Thoracic disc herniation with myelopathy.

We report a case of thoracic disc herniation in a 53-year-old woman who presented to the Emergency Department (ED) with a 2-week history of acute lower back numbness and intermittent fecal incontinence. On examination, she had lower extremity hyperreflexia, an abnormal gait, and lower lumbar pain but lacked any radicular findings. A magnetic resonance imaging scan revealed a large focal paracentral herniated disc at the T2-3 level. The patient underwent successful T2-3 anterior discectomy with T2-3 rib autograft fusion. Nine months after surgery her weakness and gait had improved, but she continued to have recurrent intermittent fecal incontinence. Thoracic disc herniation is an uncommon, but treatable cause of spinal cord compression. Prompt recognition and early treatment are the keys to preventing permanent neurologic sequelae.

Letters, libel, and the law.

Authors of scientific articles and journal editors are subject to antidefamation publication laws. We describe our experience with an accusation of libel. We define libel as it involves the medical literature and explain the ways in which threats of libel influence editorial decisionmaking and lead to negative publication bias by presenting examples drawn from the medical and legal literature.

The utility of supplemental oxygen during emergency department procedural sedation with propofol: a randomized, controlled trial.

STUDY OBJECTIVE: We determine whether supplemental oxygen reduces the incidence of hypoxia by 20% compared with breathing room air in adult study patients receiving propofol for emergency department procedural sedation. METHODS: Patients were randomized to receive either supplemental oxygen or compressed air by nasal cannula at 3 L per minute. Physicians were blinded to the gas used and end tidal CO(2) (etco(2)) data. Respiratory depression was defined a priori as oxygen saturation less than or equal to 93%, an etco(2) level of greater than or equal to 50 mm Hg, an absolute etco(2) change from baseline of greater than or equal to 10 mm Hg, or loss of the etco(2) waveform. RESULTS: Of the 110 patients analyzed, 56 received supplemental oxygen and 54 received room air. Ten (18%) patients in the supplemental oxygen group and 15 (28%) patients in the compressed air group experienced hypoxia (P=.3, effect size=10%, 95% confidence interval -24% to 7%). Twenty-seven patients (20 supplemental oxygen; 7 room air) met etco(2) criteria for respiratory depression but did not become hypoxic. Physicians identified respiratory depression in 23 of 25 patients who developed hypoxia compared with only 1 of 27 patients who met etco(2) criteria for respiratory depression but who did not have hypoxia. One patient in the supplemental oxygen group experienced a transient arrhythmia and had a short apneic episode, both of which resolved spontaneously. The patient was admitted for observation. CONCLUSION: Supplemental oxygen (3 L/minute) trended toward reducing hypoxia in adult study patients; however, the 10% difference observed was not statistically significant and was below our a priori 20% threshold. Blinded capnography frequently identified respiratory depression undetected by the treating physicians.

Incidence of occult upper gastrointestinal bleeding in patients presenting to the ED with hematochezia.

OBJECTIVE: The aim of the study was to determine the incidence of nasogastric (NG) aspiration revealing a clinically unsuspected upper gastrointestinal (GI) bleeding in patients presenting to the emergency department (ED) with hematochezia. A secondary aim was to identify factors associated with an upper GI source. METHODS: Data were prospectively collected from patients 18 years or older with either bright red blood per rectum or maroon stools. Patients were excluded if their history revealed hematemesis or their examination revealed melena, bleeding from an external hemorrhoid, or anal fissure. An NG tube was placed, and initial and postlavage aspirates were inspected and tested with Gastrocult (Beckman Coulter, Inc, Palo Alto, CA) for the presence of blood. Additional data included demographics, history, vital signs, and laboratory results. RESULTS: Of 114 patients, 11 (9.6%; 95% confidence interval, 4.9%-16.6%) had a positive NG aspirate. There were no statistically significant differences in age, sex, or race between the 2 groups. Factors associated with a positive aspirate were history of upper GI bleeding (P = .04), heart rate (P = .055), and hemoglobin (P = .03). CONCLUSION: Patients presenting to the ED with hematochezia require NG tube placement and aspiration to exclude an upper GI source of bleeding. History of an upper GI bleeding and anemia were associated with a positive NG aspirate.

The utility of supplemental oxygen during emergency department procedural sedation and analgesia with midazolam and fentanyl: a randomized, controlled trial.

STUDY OBJECTIVE: To determine whether supplemental oxygen reduces the incidence of hypoxia by 20% in study patients receiving midazolam and fentanyl for emergency department procedural sedation and analgesia. METHODS: Patients were randomized to receive either supplemental oxygen or compressed air by nasal cannula at 2 L per minute. Physicians were blinded to the gas used and end-tidal carbon dioxide (ETCO2) data. Respiratory depression was defined a priori as oxygen saturation less than 90%, ETCO2 level greater than 50 mm Hg, an absolute change from baseline of 10 mm Hg, or loss of the ETCO2 waveform. RESULTS: Of the 80 patients analyzed, 44 received supplemental oxygen and 36 received compressed air. Twenty supplemental oxygen patients and 19 compressed air patients met at least 1 criterion for respiratory depression. Six supplemental oxygen patients and 5 compressed air patients experienced hypoxia (P=.97; effect size 0%; 95% confidence interval -15% to +15%). Fourteen patients in each group met ETCO2 criteria for respiratory depression but were not hypoxic. Physicians identified respiratory depression in 8 of 11 patients who became hypoxic and 0 of 28 patients who met ETCO2 criteria for respiratory depression but who did not become hypoxic. There were no adverse events. CONCLUSION: Supplemental oxygen did not reduce (or trend toward reducing) the incidence of hypoxia in patients moderately sedated with midazolam and fentanyl. However, our lower-than-expected rate of hypoxia limits the power of this comparison. Blinded capnography frequently identified respiratory depression undetected by the treating physicians.
