Patients with COVID-19 can present to the emergency department (ED) at any point during the spectrum of illness, making it difficult to predict what level of care the patient will ultimately require. Admission to a ward bed, which is subsequently upgraded within hours to an intensive care unit (ICU) bed, represents an inability to appropriately predict the patient's course of illness. Predicting which patients will require ICU care within 24 hours would allow admissions to be managed more appropriately. ⋯ Although our model did not perform well enough to stand alone as a decision guide, it highlights certain clinical features that are associated with increased risk of decompensation.

Randomized Controlled Trial
A randomized trial comparing prescribed light exercise to standard management for emergency department patients with acute mild traumatic brain injury.
There is a paucity of effective management strategies to prevent prolonged symptoms following mild traumatic brain injury (mTBI), and emerging evidence suggesting possible benefits of exercise. The objective of this trial was to determine whether adult patients presenting to the emergency department (ED) with a diagnosis of acute mTBI prescribed light exercise were less likely to develop persistent postconcussion symptoms (PCS). ⋯ In this trial of prescribed early light exercise for acute mTBI, there were no differences in recovery or health care utilization outcomes. Results suggest that early light exercise may be encouraged as tolerated at ED discharge following mTBI, but this guidance is not sufficient to prevent PCS.

Patients with ST-elevation myocardial infarction (STEMI) require timely reperfusion, and percutaneous coronary intervention (PCI) decreases morbidity and mortality. Regionalization of STEMI care has increased timeliness and use of PCI, but it is unknown whether benefits to regionalization depend on a community's distance from its nearest PCI center. We sought to determine whether STEMI regionalization benefits, measured by access to PCI centers, timeliness of treatment (same-day or in-hospital PCI), and mortality, differ by baseline distance to nearest PCI center. ⋯ Measured by likelihood of admission to a PCI-capable facility and receipt of PCI, benefits of STEMI regionalization in California accrued only to patients whose nearest PCI center was ≥30 minutes away. We found no mortality benefits of regionalization based on distance from PCI center. Our results suggest that policymakers focus STEMI regionalization efforts in communities that are not already well serviced by PCI-capable hospitals.

Observational Study
Validation of a Clinical Decision Instrument for Emergent Neuroimaging after a Seizure: Let's Image Malignancy, Intracranial Hemorrhage, and Trauma (LIMIT).
Given the many causes of seizures, emergency physicians often utilize brain computed tomography (CT) to evaluate for intracranial pathology. However, a CT exposes patients to 100 times more radiation than a chest radiograph. Previously, we developed a four-item clinical decision instrument (CDI) to determine which patients with status epilepticus (SE) do not require emergent neuroimaging. In this study, we seek to prospectively validate our CDI in patients with a history of seizures with both SE and generalized tonic-clonic seizures. ⋯ The validation of our CDI showed improved NPV when compared to the derivation set. Use of the criteria of history of ICH, active malignancy, and trauma could have reduced the use of emergent neuroimaging in our cohort by up to 49%. This CDI should be validated in a larger subset of patients and in multiple centers prior to widespread adoption.

Emergency department (ED) patients with unexplained syncope are at risk of experiencing an adverse event within 30 days. Our objective was to systematically review the accuracy of multivariate risk stratification scores for identifying adult syncope patients at high and low risk of an adverse event over the next 30 days. ⋯ Many risk stratification scores are not validated or not sufficiently accurate for clinical use. The CSRS is an accurate validated prediction score for ED patients with unexplained syncope. Its impact on clinical decision making, admission rates, cost, or outcomes of care is not known.
