UNASSIGNED: Emergency departments are the primary entry point for emergencies in the public healthcare system. Resource constraints burden a large proportion of the public hospital emergency departments, which includes limited access to radiological services. Emergency point-of-care ultrasound provides a tool capable of bridging this gap. The Eastern Cape is yet to describe the utilisation of emergency point-of-care ultrasound in any of its emergency departments.
UNASSIGNED: Frere Hospital initiated a clinical audit to assess the utilisation of emergency point-of-care ultrasound in its emergency department in 2022. This study was a retrospective review of the audit between 01 November 2022 until 28 February 2023. Data from the handwritten register regarding patient\'s presenting complaints and provisional diagnoses was also captured during the study period to draw comparisons between burden of disease and use of emergency point-of-care ultrasound.
UNASSIGNED: A total of 9501 patients attended Frere Hospital\'s emergency department over the study period with 492 emergency point-of-care ultrasounds performed (overall utilisation rate 5.2 %). The five credentialed emergency point-of-care ultrasound providers performed the majority (n = 360, 73.2 %) of the applications, compared to 132 (26.8 %) performed by the seven non-credentialed providers. The extended focused abdominal sonography in trauma (eFAST) was the most frequently performed application (n = 140, 28.5 %).
UNASSIGNED: Emergency point-of-care ultrasound is underutilised in Frere Hospital\'s emergency department. The varied casemix requires upskilling of clinicians in emergency point-of-care ultrasound to suit the burden of disease experienced in the department. Ongoing emergency point-of-care ultrasound training, credentialing and research is important to ensure appropriate and quality emergency point-of-care ultrasound utilisation.

Any patient presenting with trismus should have tetanus considered as a differential diagnosis. Early recognition, timely treatment and supportive care can improve patient outcomes. Treatment with tetanus immunoglobulin to neutralize the toxin, antimicrobials to treat the infection and sedation in the intensive care unit are key therapeutic options.

BACKGROUND: Cardiopulmonary resuscitation is a crucial skill for emergency medical services. As high-risk-low-frequency events pose an immense mental load to providers, concepts of crew resource management, non-technical skills and the science of human errors are intended to prepare healthcare providers for high-pressure situations. However, medical errors occur, and organizations and institutions face the challenge of providing a blame-free error culture to achieve continuous improvement by avoiding similar errors in the future. In this case, we report a critical medical error during an anaphylaxis-associated cardiac arrest, its handling and the unexpected yet favourable outcome for the patient.
METHODS: During an out-of-hospital cardiac arrest due to chemotherapy-induced anaphylaxis, a patient received a 10-fold dose of epinephrine due to shortcomings in communication and standardization via a central venous port catheter. The patient converted from a non-shockable rhythm into a pulseless ventricular tachycardia and subsequently into ventricular fibrillation. The patient was cardioverted and defibrillated and had a return of spontaneous circulation with profound hypotension only 6 min after the administration of 10 mg epinephrine. The patient survived without any residues or neurological impairment.
CONCLUSIONS: This case demonstrates the potential deleterious effects of shortcomings in communication and deviation from standard protocols, especially in emergencies. Here, precise instructions, closed-loop communication and unambiguous labelling of syringes would probably have avoided the epinephrine overdose central to this case. Interestingly, this serious error may have saved the patient\'s life, as it led to the development of a shockable rhythm. Furthermore, as the patient was still in profound hypotension after administering 10 mg of epinephrine, this high dose might have counteracted the severe vasoplegic state in anaphylaxis-associated cardiac arrest. Lastly, as the patient was receiving care for advanced malignancy, the likelihood of termination of resuscitation in the initial non-shockable cardiac arrest was significant and possibly averted by the medication error.

UNASSIGNED: Implementation and sustainability of new care processes in emergency departments (EDs) is difficult. We describe experiences of implementing geriatric care processes in EDs that upgraded their accreditation level for the Geriatric Emergency Department Accreditation (GEDA) program. These EDs can provide a model for adopting and sustaining guidelines for evidence-based geriatric care.
UNASSIGNED: We performed qualitative interviews with geriatric ED nurse and physician leaders overseeing their ED\'s geriatric accreditation processes. The interview guide was based on the Consolidated Framework for Implementation Research (CFIR), a framework consisting of a comprehensive set of factors that impact implementation of evidence-based interventions. We used inductive analysis to elucidate key themes from interviews and deductive analysis to map themes onto CFIR constructs.
UNASSIGNED: Clinician leaders from 15 of 19 EDs that upgraded accreditation status by March 1, 2023 participated in interviews. Motivations to upgrade accreditation level centered on improving patient care (73%) and achieving recognition (56%). Rationales for choosing specific care processes were more commonly related to feasibility (40%) and ability to integrate the processes into the electronic health record (33%) than to site-specific patient needs (20%). Several common experiences in implementation were identified: (1) financing from the larger health system or philanthropy was crucial; (2) translating the Geriatric ED Guidelines into clinical practice was challenging for clinician leaders; (3) motivational barriers existed among frontline ED staff; (4) longitudinal staff education was needed given frontline ED staff attrition and turnover; and (5) the electronic health record facilitated implementation of geriatric screenings.
UNASSIGNED: Geriatric ED accreditation involves significant time, resource allocation, and longitudinal staff commitment. EDs pursuing geriatric accreditation balance aspirations to improve patient care with resource availability to implement new care processes and competing priorities.

UNASSIGNED: Medical educational societies have emphasized the inclusion of marginalized populations, including the lesbian, gay, bisexual, transgender and queer (LGBTQ+) population, in educational curricula. Lack of inclusion can contribute to health inequality and mistreatment due to unconscious bias. Little didactic time is spent on the care of LGBTQ+ individuals in emergency medicine (EM) curricula. Simulation based medical education can be a helpful pedagogy in teaching cross-cultural care and communication skills. In this study, we sought to determine the representation of the LGBTQ+ population in EM simulation curricula. We also sought to determine if representations of the LGBTQ+ population depicted stigmatized behavior.
UNASSIGNED: We reviewed 971 scenarios from six simulation case banks for LGBTQ+ representation. Frequency distributions were determined for major demographic variables. Chi-Squared or Fisher\'s Exact Test, depending on the cell counts, were used to determine if relationships existed between LGBTQ+ representation and bank type, author type, and stigmatized behavior.
UNASSIGNED: Of the 971 scenarios reviewed, eight (0.82%) scenarios explicitly represented LGBTQ+ patients, 319 (32.85%) represented heterosexual patients, and the remaining 644 (66.32%) did not specify these patient characteristics. All cases representing LGBTQ+ patients were found in institutional case banks. Three of the eight cases depicted stigmatized behavior.
UNASSIGNED: LGBTQ+ individuals are not typically explicitly represented in EM simulation curricula. LGBTQ+ individuals should be more explicitly represented to reduce stigma, allow EM trainees to practice using gender affirming language, address health conditions affecting the LGBTQ+ population, and address possible bias when treating LGBTQ+ patients.

Community-acquired pneumonia is a common cause of acute hospitalisation. Identifying patients with community-acquired pneumonia among patients suspected of having the disease can be a challenge, which causes unnecessary antibiotic treatment. We investigated whether the circulatory pulmonary injury markers surfactant protein D (SP-D), Krebs von den Lungen-6 (KL-6), and Club cell protein 16 (CC16) could help identify patients with community-acquired pneumonia upon acute admission. In this multi-centre diagnostic accuracy study, SP-D, KL-6, and CC16 were quantified in plasma samples from acutely hospitalised patients with provisional diagnoses of community-acquired pneumonia. The area under the receiver operator characteristics curve (AUC) was calculated for each marker against the following outcomes: patients\' final diagnoses regarding community-acquired pneumonia assigned by an expert panel, and pneumonic findings on chest CTs. Plasma samples from 339 patients were analysed. The prevalence of community-acquired pneumonia was 63%. AUCs for each marker against both final diagnoses and chest CT diagnoses ranged between 0.50 and 0.56. Thus, SP-D, KL-6, and CC16 demonstrated poor diagnostic performance for community-acquired pneumonia in acutely hospitalised patients. Our findings indicate that the markers cannot readily assist physicians in confirming or ruling out community-acquired pneumonia.

BACKGROUND: Disturbances in potassium levels can induce ventricular arrhythmias and heighten mortality in patients with ST-elevation myocardial infarction (STEMI). This study evaluates the influence of sK levels on seven-day mortality and incidence of ventricular arrhythmias in STEMI patients to further improve clinical guidelines and outcomes.
METHODS: This retrospective, propensity-matched study analyzed approximately 250,000 acute STEMI patients from 55 major academic medical centers/healthcare organizations (HCOs) in the US Collaborative Network of the TriNetX database. The sK levels recorded on the day of STEMI diagnosis were categorized into four cohorts: sK ≤ 3.4 (hypokalemia), 3.5 ≤ sK ≤ 4.5 (normal-control), 4.6 ≤ sK ≤ 5.0 (high-normal), and sK ≥ 5.1 (hyperkalemia). Patient cohorts were propensity-matched using linear and logistic regression for demographics. Outcomes of seven-day mortality, ventricular tachycardia (VT), and ventricular fibrillation (VF) were compared between these cohorts and the control group.
RESULTS: The analysis showed hypokalemia was linked to significantly higher seven-day mortality (7.2% vs. 4.3%; RR 1.69; p<0.001), and increased rates of VT and VF. Similarly, hyperkalemia was associated with elevated mortality (12.7% vs. 4.6%; RR 2.76; p<0.001), VT, and VF rates. High-normal sK levels showed increased mortality (7.4% vs. 4.7%; RR 1.58; p<0.001), but unchanged VT or VF rates compared to the normal sK group.
CONCLUSIONS: This comprehensive study highlights the correlation of sK levels with death in STEMI patients, revealing a nearly doubled risk of mortality with hypokalemia and almost triples with hyperkalemia. More notably, the mortality for STEMIs is higher for high-normal vs normal sK values. Additionally, hypokalemia and hyperkalemia were found to significantly elevate VT and VF risks.

UNASSIGNED: Research suggests that quantitative metric reports can improve the clinical performance of emergency physicians; however, few studies have examined their effects on physicians in training. The primary study objective was to assess the effects of providing emergency medicine (EM) residents with individualized throughput metrics with regard to emergency department (ED) disposition times.
UNASSIGNED: We performed a single-center, retrospective, observational study from January 2021 to December 2022 examining ED disposition times before and after providing upper-level EM residents individualized throughput metrics. Residents received monthly reports of three specific metrics averaged over the preceding 6 months: (1) median time from room to discharge order (Rm2Dc), (2) median time from return of all results to discharge order (Rlts2Dc), and (3) median time from room and to consult order for hospitalization (Rm2Hosp). Overall mean values of the three metrics before and during metric sharing were compared via independent t-test and stratified by level of training and time of year. Adjusted analysis was performed to control for temporal differences between study periods. Testing was conducted at α = 0.05 level of significance.
UNASSIGNED: A total of 35 unique residents were included in the analysis. Overall, mean disposition times were not significantly different before and during reporting of metrics: Rm2Dc (154.8 min vs. 148.9 min, p = 0.109), Rslt2Dc (46.5 min vs. 45.1 min, p = 0.522), and Rm2Hosp (141.7 min vs. 135.7 min, p = 0.257). Subgroup analysis yielded similar results, aside from a significant decrease in mean Rm2Hosp in the postgraduate year-3 (PGY-3) group (145.8 min vs. 124.1 min, p = 0.004). Analysis with adjusted means yielded results similar to those observed with unadjusted data.
UNASSIGNED: Overall, individualized throughput metrics were not correlated with decreased average times to ED disposition for upper-level EM residents; however, in the subset of hospitalized patients seen by PGY-3 residents, we observed a mean decrease of 21.7 min to consultation.

Pediatric intussusception is a relatively common yet serious condition where prompt diagnosis is crucial. Point-of-care ultrasound (POCUS) has proven accurate for diagnosing this disease and can expedite both diagnosis and treatment. Previous research has shown that emergency physicians can diagnose intussusception with acceptable sensitivity and specificity but require prior training in recognizing the pathology. Despite the disease\'s relative frequency, any individual physician rarely encounters it, making a simulation model vital for learning this ultrasound modality. We created a model using low-cost, easily available components that can be used to train emergency physicians to diagnose intussusception on POCUS.

Through a review of current research, standards of care, and best practices, this paper serves as a resource for emergency physicians (EPs) caring for persons who identify as transgender and gender diverse (T/GD) in the emergency department (ED). Both patient- and physician-based research have identified existent potential knowledge gaps for EPs caring for T/GD in the ED. T/GD have negative experiences related to their gender identity when seeking emergency medical care and may even delay emergency care for fear of discrimination. Through the lens of cultural humility, this paper aims to address potential knowledge gaps for EPs, identify and reduce barriers to care, highlight gender-affirming hospital policies and protocols, and improve the care and experience of T/GD in the ED.
