Patient Sociodemographic Factors Are Associated with Receiving Point-of-care Ultrasound in the Emergency Department.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPoint-of-care ultrasound (POCUS) is widely used in emergency medicine (EM) and increasingly throughout healthcare. Prior studies have revealed disparities in the use of imaging in the emergency department (ED) based on sociodemographic factors; however, the association between these factors and POCUS use is unknown. Our aim was to compare the odds of receiving POCUS in the ED based on patient race and ethnicity, language, sex, and type of insurance.
methodsWe reviewed electronic health records (EHR) matched to a departmental POCUS database from November 2021-June 2023 at an academic Level I trauma center. We included ED patients diagnosed with an International Classification of Diseases code mapped to chest or flank pain, who had a cardiac troponin obtained, or had been evaluated as a trauma activation or alert. Our primary outcome was whether a patient received transthoracic echocardiography (cardiac), renal, or focused assessment with sonography in trauma. Predictor variables were race/ethnicity group (non-Hispanic [NH] White, NH Black, Hispanic, other), patient language, sex assigned at birth, and insurance type as recorded in the EHR. We performed descriptive analyses and logistic regression (adjusted odds ratio [aOR], 95% confidence interval [CI]) controlling for body mass index, age, comorbidities, and triage hypotension or tachycardia.
resultsOf the 25,389 ED patients meeting inclusion criteria, 79.5% were NH White, 95.3% listed English as their primary language, 51.5% were female, and 33.4% had private payor insurance. After adjusting for confounding, patients had lower odds of receiving POCUS if they were "other" race/ethnicity as compared to NH White (aOR 0.65, CI 0.42-0.99, P = .04), female as compared to male (aOR 0.81, CI 0.69-0.94, P = .007), or if they had Medicare (aOR 0.67, CI 0.54-0.84, P <.001) or Medicaid (aOR 0.66, CI 0.52-0.83, P = .001) as compared to private payors.
conclusionOverall, patients of female sex and patients with Medicaid or Medicare had lower odds of receiving point-of-care ultrasound in the ED. Although we did not find a difference in POCUS use among non-Hispanic White, NH Black, and Hispanic patients, patients belonging to other race/ethnicity categories had lower odds of receiving POCUS compared to NH White patients.
