Emergency departments (EDs) are often patients' first point of contact with the health care system. Race, ethnicity, and language all influence factors leading up to ED visits and patient experiences within the ED. There is limited evidence showing how race, ethnicity, and language interact to shape ED experiences, particularly during the COVID-19 pandemic when EDs were extremely strained. ⋯ Findings suggest multiple mechanisms influence hospital admissions for patients who are racially and ethnically minoritized and speak Spanish. Providers may have admitted patients as a precaution rather than because of more advanced illness. Evaluating race, ethnicity, and language concurrently can reveal how intersectional factors shape patient experiences in the ED.

The Pulmonary Embolism Rule-Out Criteria (PERC), developed to minimize unnecessary testing in low-risk pulmonary embolism (PE) cases, lacks clear validation in the context of COVID-19. ⋯ The study demonstrates that the sensitivity and negative predictive value of the PERC are comparable in COVID-19 positive and negative patients. Furthermore, the incidence of PE among patients presenting to the emergency department did not significantly differ based on COVID-19 status. While this study highlights the relevance of the PERC in clinical decision-making, caution is advised as the PERC may not always provide reliable results when used as the sole diagnostic test.

The focused assessment with sonography in trauma (FAST) examination plays an essential role in diagnosing hemoperitoneum in trauma patients to guide prompt operative management. The FAST examination is highly specific for hemoperitoneum in trauma patients, and has been adopted in nontrauma patients to identify intraperitoneal fluid as a cause of abdominal pain or distension. However, causes of false positive FAST examinations have been described and require prompt recognition to avoid diagnostic uncertainty and inappropriate procedures. Most causes of false positive FAST examinations are due to anatomic mimics such as perinephric fat or seminal vesicles, however, modern ultrasound machines use a variety of postprocessing image enhancement techniques that can also lead to novel false positive artifacts. ⋯ We report cases where experienced clinicians incorrectly interpreted ultrasound findings caused by a novel mimic of hemoperitoneum: the "lipliner sign." It appears most prominently at the edges of solid organs (such as the liver and the spleen), which is the same location most likely to show free fluid in FAST examination in trauma patients. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Clinicians who take care of trauma patients must be familiar with causes of false positive FAST examinations that could lead to a misdiagnosis of hemoperitoneum.

Three validated diagnostic algorithms for diagnosing patients with acute onset dizziness or vertigo (HINTS, HINTS-plus and STANDING) exist. All are extremely accurate in distinguishing peripheral from central causes of dizziness when done by experienced clinicians. ⋯ Use of these validated algorithms is the best way to accurately diagnose patients with acute dizziness. For clinicians who are unfamiliar with or uncomfortable performing or interpreting HINTS and STANDING, this article will suggest alternative approaches to help with accurate diagnosis of patients with acute dizziness or vertigo.
