Background:Previous studies describe significant rates of misdiagnosis of stroke, seizure and other neurological problems, but there are few studies examining diagnostic accuracy of all emergency referrals to a neurology service. This information could be useful in focusing the neurological education of physicians who assess and refer patients with neurological complaints in emergency departments.Methods:All neurological consultations in the emergency department at a tertiary-care teaching hospital were recorded for six months. The initial diagnosis of the requesting physician was recorded for each patient. This was compared to the initial diagnosis of the consulting neurologist and to the final diagnosis, as determined by retrospective chart review.Results:Over a six-month period, 493 neurological consultations were requested. The initial diagnosis of the requesting physician agreed with the final diagnosis in 60.4% (298/493) of cases, and disagreed or was uncertain in 35.7% of cases (19.1% and 16.6% respectively). In 3.9% of cases, the initial diagnosis of both the referring physician and the neurologist disagreed with the final diagnosis. Common misdiagnoses included neurocardiogenic syncope, peripheral vertigo, primary headache and psychogenic syndromes. Often, these were initially diagnosed as stroke or seizure.Conclusions:Our data indicate that misdiagnosis or diagnostic uncertainty occurred in over one-third of all neurological consultations in the emergency department setting. Benign neurological conditions, such as migraine, syncope and peripheral vertigo are frequently mislabeled as seizure or stroke. Educational strategies that emphasize emergent evaluation of these common conditions could improve diagnostic accuracy, and may result in better patient care.

ABSTRACT Objective: Acetylsalicylic acid (ASA) is a simple and cost-effective treatment for acute coronary syndromes (ACS). Our objectives were to determine the frequency of ASA administration in the emergency department (ED) for patients with acute myocardial infarction or unstable angina, and to identify patient characteristics associated with its administration. Methods: This is a retrospective chart review of patients discharged with a final diagnosis of ACS. Data on age, gender, mode of presentation, presence of chest pain at triage, administration of ASA or not in the ED, dosage and form of ASA received, timing of administration, presence of contraindications to ASA and use of regular ASA prior to ED presentation were recorded. Results: Six hundred and one charts were analyzed. Five hundred and fifty patients (91.5%) received ASA. Only 444 (73.9%) of these 550 patients were administered the ASA appropriately, according to the American Heart Association / American College of Cardiology (AHA/ACC) guidelines. Univariate analysis showed that chart notes “Transport by ambulance,” “Allergy to ASA” and “Gastrointestinal bleed” were associated with a lower probability of the patient being administered ASA. If a patient was noted as taking ASA regularly, it increased the chance of this patient being administered ASA in the ED. Conclusion: Although the study ED performed well, administering ASA to 91.5% of patients with ACS, only 73.9% of the patients who received ASA were administered the ASA appropriately, as recommended in the AHA/ACC guidelines. Educational strategies and system changes are necessary to increase the proportion of eligible ACS patients who receive appropriate ASA therapy.

Background: Some 20% of patients with stable Chronic Obstructive Pulmonary Disease (COPD) might have heart failure (HF). HF contribution to acute exacerbations of COPD (AECOPD) presenting to the emergency department (ED) is not well established. Aims: To assess (1) the HF incidence in patients presenting to the ED with AECOPD; (2) the concordance between ED and respiratory ward (RW) diagnosis; (3) the factors associated with risk of death after hospital discharge. Methods: Retrospective chart review of 119 COPD patients presenting to ED for acute exacerbation of respiratory symptoms and then admitted to RW where a final diagnosis of AECOPD, AECOPD and HF and AECOPD and OD (other diagnosis), was obtained. ED and RW diagnosis were then compared. Factors affecting survival at follow-up were investigated. Results: At RW, 40.3% of cases were diagnosed of AECOPD, 40.3% of AECOPD and HF and 19.4% of AECOPD and OD, with ED diagnosis coinciding with RW’s in 67%, 23%, and 57% of cases respectively. At RW, 60% of patients in GOLD1 had HF, of which 43% were diagnosed at ED, while 40% in GOLD4 had HF that was never diagnosed at ED. Lack of inclusion in a COPD care program, HF, and early readmission for AECOPD were associated with mortality. Conclusions: HF is highly prevalent and difficult to diagnose in patients in all GOLD stages presenting to the ED with severe AECOPD, and along with lack of inclusion in a COPD care program, confers a high risk for mortality.

Cannabinoid Hyperemesis Syndrome

Introduction: Cannabinoid Hyperemesis Syndrome (CHS) in pediatric patients is poorly characterized. Literature is scarce, making identification and treatment challenging. This study's objective was to describe demographics and visit data of pediatric patients presenting to the emergency department (ED) with suspected CHS, in order to improve understanding of the disorder. Methods: A retrospective chart review was conducted of pediatric patients (12-17 years) with suspected CHS presenting to one of two tertiary-care EDs; one pediatric and one pediatric/adult (combined annual pediatric census 40,550) between April 2014-March 2019. Charts were selected based on discharge diagnosis of abdominal pain or nausea/vomiting with positive cannabis urine screen, or discharge diagnosis of cannabis use, using ICD-10 codes. Patients with confirmed or likely diagnosis of CHS were identified and data including demographics, clinical history, and ED investigations/treatments were recorded by a trained research assistant. Results: 242 patients met criteria for review. 39 were identified as having a confirmed or likely diagnosis of CHS (mean age 16.2, SD 0.85 years with 64% female). 87% were triaged as either CTAS-2 or CTAS-3. 80% of patients had cannabis use frequency/duration documented. Of these, 89% reported at least daily use, the mean consumption was 1.30g/day (SD 1.13g/day), and all reported ≥6 months of heavy use. 69% of patients had at least one psychiatric comorbidity. When presenting to the ED, all had vomiting, 81% had nausea, 81% had abdominal pain, and 30% reported weight loss. Investigations done included venous blood gas (30%), pregnancy test in females (84%), liver enzymes (57%), pelvic or abdominal ultrasound (19%), abdominal X-ray (19%), and CT head (5%). 89% of patients received treatment in the ED with 81% receiving anti-emetics, 68% receiving intravenous (IV) fluids, and 22% receiving analgesics. Normal saline was the most used IV fluid (80%) and ondansetron was the most used anti-emetic (90%). Cannabis was suspected to account for symptoms in 74%, with 31% of these given the formal diagnosis of CHS. 62% of patients had another visit to the ED within 30 days (prior to or post sentinel visit), 59% of these for similar symptoms. Conclusion: This study of pediatric CHS reveals unique findings including a preponderance of female patients, a majority that consume cannabis daily, and weight loss reported in nearly one third. Many received extensive workups and most had multiple clustered visits to the ED.

Introduction: Formal ultrasound imaging, with use of ultrasound technicians and radiologists, provides a valuable diagnostic component to patient care in the Emergency Department (ED). Outside of regular weekday hours, ordering formal ultrasounds can produce logistical difficulties. EDs have developed protocols for next-day ultrasounds, where the patient returns the following day for imaging and reassessment by an ED physician. This creates additional stress on ED resources – personnel, bed space, finances – that are already strained. There is a dearth of literature regarding the use of next-day ultrasounds or guidelines to direct efficient use. This study sought to accumulate data on the use of ED next-day ultrasounds and patient oriented clinical outcomes. Methods: This study was a retrospective chart review of 150 patients, 75 from each of two different tertiary care hospitals in Saskatoon, Saskatchewan. After a predetermined start date, convenience samples were collected of all patients who had undergone a next-day ultrasound ordered from the ED until the quota was satisfied. Patients were identified by an electronic medical record search for specific triage note phrases indicating use of next-day ultrasounds. Different demographic, clinical, and administrative parameters were collected and analyzed. Results: Of the 150 patients, the mean age was 35.9 years and 75.3% were female. Median length of stay for the first visit was 4.1 hours, and 2.2 hours for the return visit. Most common ultrasound scans performed were abdomen and pelvis/gyne (34.7%), complete abdomen (30.0%), duplex extremity venous (10.0%). Most common indications on the ultrasound requisition were nonspecific abdominal pain (18.7%), vaginal bleeding with or without pregnancy (17.3%), and hepatobiliary pathology (15.3%). Ultrasounds results reported a relevant finding 56% of the time, and 34% were completely normal. After the next-day ultrasound 5.3% of patients had a CT scan, 10.7% had specialist consultation, 8.2% were admitted, and 7.3% underwent surgery. Conclusion: Information was gathered to close gaps in knowledge about the use of next-day ultrasounds from the ED. A large proportion of patients are discharged home without further interventions. Additional research and the development of next-day ultrasound guidelines or outpatient pathways may improve patient care and ED resource utilization.

BackgroundBedside lung ultrasound (LUS) is an affordable diagnostic tool that could contribute to identifying COVID-19 pneumonia. Different LUS protocols are currently used at the emergency department (ED) and there is a need to know their diagnostic accuracy.DesignA multicentre, prospective, observational study, to compare the diagnostic accuracy of three commonly used LUS protocols in identifying COVID-19 pneumonia at the ED.Setting/patientsAdult patients with suspected COVID-19 at the ED, in whom we prospectively performed 12-zone LUS and SARS-CoV-2 reverse transcription PCR.MeasurementsWe assessed diagnostic accuracy for three different ultrasound protocols using both PCR and final diagnosis as a reference standard.ResultsBetween 19 March 2020 and 4 May 2020, 202 patients were included. Sensitivity, specificity and negative predictive value compared with PCR for 12-zone LUS were 91.4% (95% CI 84.4 to 96.0), 83.5% (95% CI 74.6 to 90.3) and 90.0% (95% CI 82.7 to 94.4). For 8-zone and 6-zone protocols, these results were 79.7 (95% CI 69.9 to 87.6), 69.0% (95% CI 59.6 to 77.4) and 81.3% (95% CI 73.8 to 87.0) versus 89.9% (95% CI 81.7 to 95.3), 57.5% (95% CI 47.9 to 66.8) and 87.8% (95% CI 79.2 to 93.2). Negative likelihood ratios for 12, 8 and 6 zones were 0.1, 0.3 and 0.2, respectively. Compared with the final diagnosis specificity increased to 83.5% (95% CI 74.6 to 90.3), 78.4% (95% CI 68.8 to 86.1) and 65.0% (95% CI 54.6 to 74.4), respectively, while the negative likelihood ratios were 0.1, 0.2 and 0.16.ConclusionIdentifying COVID-19 pneumonia at the ED can be aided by bedside LUS. The more efficient 6-zone protocol is an excellent screening tool, while the 12-zone protocol is more specific and gives a general impression on lung involvement.Trial registration numberNL8497.

Objective: To determine the clinical and imaging diagnostic accuracy in adult patients presenting to the Emergency Department with groin abscess. Method: Retrospective chart review of all adult patients presenting to a district general hospital with a provisional diagnosis of groin abscess was undertaken from January 2019 to December 2019. A proforma was used to capture data such as the age, sex, co-morbidities, grade of assessing clinician and imaging profile. Results: 39 patients with a provisional diagnosis of groin abscess were identified; representing approximately 1% of all ED attendances. There were 21 males and 18 females. The age range was from 23 to 73 years (mean age 42). The abscess was located on the left side in 19 patients (49%), 18 (46%) on the right and 2 (5%) were bilateral. The overall rate of correct diagnosis of the ED clinicians compared to CT diagnosis is indicated by a sensitivity of 82%, positive predictive value of 90% and an accuracy of 75%. 22 patients had CT scan which confirmed an abscess in 18 (83%). Conclusion: Groin abscess is a rare presentation to the Emergency department. Most patients were seen by clinicians below the consultant grade. Diagnostic accuracy was highest amongst physicians.

AbstractObjectiveThe objective of this study was to determine the proportion of women who had a ruptured ectopic pregnancy after being discharged from the emergency department (ED) where ectopic pregnancy had not yet been excluded.MethodsThis was a retrospective chart review of pregnant (<12-week gestational age) women discharged home from an academic tertiary care ED with a diagnosis of ectopic pregnancy, rule-out ectopic pregnancy, or pregnancy of unknown location over a 7-year period.ResultsOf the 550 included patients, 83 (15.1%) had a viable pregnancy, 94 (17.1%) had a spontaneous or missed abortion, 230 (41.8%) had an ectopic pregnancy, 72 (13.1%) had unknown outcomes, and 71 (12.9%) had other outcomes that included therapeutic abortion, molar pregnancy, or resolution of βHCG with no location documented. Of the 230 ectopic pregnancies, 42 (7.6%) underwent expectant management, 131 (23.8%) were managed medically with methotrexate, 29 (5.3%) were managed with surgical intervention, and 28 (5.1%) patients had a ruptured ectopic pregnancy after their index ED visit. Of the 550 included patients, 221 (40.2%) did not have a transvaginal ultrasound during their index ED visit, and 73 (33.0%) were subsequently diagnosed with an ectopic pregnancy.ConclusionThese results may be useful for ED physicians counselling women with symptomatic early pregnancies about the risk of ectopic pregnancy after they are discharged from the ED.

Impaired Consciousness

Background: The approach to unconscious patients in the emergency department (ED) is difficult, often depends on local resources and interests, and workup strategies often lack standardization. One reason for this is that data on causes, management, and outcome of patients who present to the ED with sudden onset unconsciousness of unknown cause is limited. Objectives: This study was performed to analyze the causes of acute impaired consciousness in patients in an interdisciplinary ED. Methods: Here, we analyzed all patients who were admitted to the ED of a tertiary care hospital with the dominating symptom of “sudden onset unconsciousness” within 1 year (September 2014 until August 2015). Patients with a clear diagnosis at arrival that explained the altered state of consciousness or other dominating symptoms at the time of arrival were not included. Results: A total of 212 patients were analyzed. In 88% of the patients, a final diagnosis could be established in the ED. Most common causes for unconsciousness were cerebrovascular diseases (24%), infections (14%), epileptic seizures (12%), psychiatric diseases (8%), metabolic causes (7%), intoxications (7%), transient global amnesia (5%), and cardiovascular causes (4%). The diagnoses were predominantly established by physical examination in combination with computed tomography (23%) and by the results of laboratory testing (25%). In-hospital mortality was 11%, and 59% of all patients were discharged with a Glasgow Outcome Score of 2–4. Conclusions: This analysis demonstrates a large variety of etiologies in patients with unknown unconsciousness of acute onset who are admitted to an ED. As neurological diagnoses are among the most common etiologies, neurological qualification is required in the ED, and availability of diagnostics such as cerebral imaging is indispensable and recommended as an early step in a standardized clinical approach.

Background: Laboratory and radiographic tests are often repeated during inter-hospital transfers from secondary to tertiary emergency departments (ED), despite available data from the sending structure. The aim of this study was to identify the proportion of repeated tests in patients transferred to a tertiary care ED, and to estimate their inappropriateness and their costs. Methods: A retrospective chart review of all adult patients transferred from one secondary care ED to a tertiary care ED during the year 2016 was carried out. The primary outcome was the redundancy (proportion of procedure repeated in the 8 h following the transfer, despite the availability of the previous results). Factors predicting the repetition of procedures were identified through a logistic regression analysis. Two authors independently assessed inappropriateness. Results: In 2016, 432 patients were transferred from the secondary to the tertiary ED, and 251 procedures were repeated: 179 patients (77.2%) had a repeated laboratory test, 34 (14.7%) a repeated radiological procedure and 19 (8.2%) both. Repeated procedures were judged as inappropriate for 197 (99.5%) laboratory tests and for 39 (73.6%) radiological procedures. Conclusion: Over half of the patients transferred from another emergency department had a repeated procedure. In most cases, these repeated procedures were considered inappropriate.
