Background The use of simulation-based team training has increased over the past decades. Simulation-based team training within emergency medicine and critical care contexts is best known for its use by trauma teams and teams involved in cardiac arrest. In the domain of emergency medicine, simulation-based team training is also used for other typical time-critical clinical presentations. We aimed to review the existing literature and current state of evidence pertaining to non-technical skills obtained via simulation-based team training in emergency medicine and critical care contexts, excluding trauma and cardiac arrest contexts. Methods This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Before the initiation of the study, the protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database. We conducted a systematic literature search of 10 years of publications, up to December 17, 2019, in the following databases: PubMed/MEDLINE, EMBASE, Cochrane Library, and CINAHL. Two authors independently reviewed all the studies and extracted data. Results Of the 456 studies screened, 29 trials were subjected to full-text review, and 13 studies were included in the final review. None of the studies was randomized controlled trials, and no studies compared simulation training to different modalities of training. Studies were heterogeneous; they applied simulation-training concepts of different durations and intensities and used different outcome measures for non-technical skills. Two studies reached Kirkpatrick level 3. Out of the remaining 11 studies, nine reached Kirkpatrick level 2, and two reached Kirkpatrick level 1. Conclusions The literature on simulation-based team training in emergency medicine is heterogeneous and sparse, but somewhat supports the hypothesis that simulation-based team training is beneficial to teams’ knowledge and attitudes toward non-technical skills (Kirkpatrick level 2). Randomized trials are called for to clarify the effect of simulation compared to other modalities of team training. Future research should focus on the transfer of skills and investigate improvements in patient outcomes (Kirkpatrick level 4).
BackgroundEmergency department (ED) patients present with complaints and not diagnoses. Characterization and risk stratification based on chief complaint can therefore help clinicians improve ED workflow and clinical outcome. In this study we investigated the 30-day mortality and readmission among ED patients based on chief complaint.MethodsIn this cohort study we retrieved routinely collected data from electronic medical records and the Danish Civil Registration System of all ED contacts from July 1, 2016 through June 30, 2017. All patients triaged with one chief complaint using the Danish Emergency Process Triage system were included. Patients with minor injuries were excluded. The chief complaint assigned by the triaging nurse was used as exposure, and 30-day mortality and 30-day readmission were the primary outcomes. Logistic regression was used to determine crude and adjusted ORs with reference to the remaining study population.ResultsA total of 41 470 patients were eligible. After exclusion of minor injuries and patients not triaged, 19 325 patients were included. The 30-day mortality and 30-day readmission differed significantly among the chief complaints. The highest 30-day mortality was observed among patients presenting with altered level of conscousness (ALOC) (8.4%, OR=2.0, 95% CI 1.3 to 3.1) and dyspnea (8.0%, OR=2.1, 95% CI 1.6 to 2.6). 30-day readmission was highest among patients presenting with fever/infection (11.7%, OR=1.9, 95% CI 1.4 to 2.4) and dyspnea (11.2%, OR=1.7, 95% CI 1.4 to 2.0).DiscussionChief complaint is associated with 30-day mortality and readmission in a mixed ED population. ALOC and dyspnea had the highest mortality; fever/infection and dyspnea had the highest readmission rate. This knowledge may assist in improving and optimizing symptom-based initial diagnostic workup and treatment, and ultimately improve workflow and clinical outcome.Level of evidenceLevel III.
Background In this study we aimed to assess if a focused lung ultrasound examination predict the need for mechanical ventilation admission to an intensive care unit, high-flow oxygen treatment, death of COVID-19 within 30 days and 30-day all-cause mortality in patients with clinical suspicion of COVID-19 or PCR-verified SARS-CoV-2 infection. Methods A multicenter prospective cohort trial was performed. Film clips from focused lung ultrasound examinations were recorded and rated by blinded observers using different scoring systems. A prediction model was built and used to test relationship between lung ultrasound scores and clinical outcomes. Diagnostic performance of scoring systems was analysed. Results A total of 3889 film clips of 398 patients were analysed. Patients who had any of the outcomes of interest had a significantly higher ultrasound score than those who did not. Multivariable logistic regression analyses showed that lung ultrasound predicts mechanical ventilation (RR 2.44, 95% CI 1.32–5.52), admission to intensive care (RR 2.55, 95% CI 1.41–54.59) and high-flow oxygen treatment (RR 1.95, 95% CI 1.5–2.53) but not survival when adjusting for sex, age and relevant comorbidity. There was no diagnostic difference in AUC-ROC between a scoring system using only anterolateral thorax zones and a scoring system that also included dorsal zones. Conclusion Focused lung ultrasound in patients with clinical suspicion of COVID-19 predicts respiratory failure requiring mechanical ventilation, admission to intensive care units and high-flow oxygen. Thus, focused lung ultrasound may be used to risk stratify patients with COVID-19 symptoms.
