Effects of point-of-care ultrasonography on clinical decisions for suspected hypervolemia: a cross-sectional study of two independent samples.

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) usage is rapidly expanding into clinical practice. One of the clinical uses of POCUS is assessing the volume status, considering the limitation of evaluating congestion with the clinical exam.
objectiveEvaluate whether POCUS modified therapeutic plans regarding the patient's volemic status (fluid infusion, diuretic, and vasodilator therapy).
methodsCross-sectional observational study performed in hospitalized patients in general clinical wards of two large public teaching hospitals in Brazil (initial and confirmatory sets). Following the request for a POCUS evaluation, physicians were asked if the ultrasound information impacted therapeutic decisions.
resultsA total of 139 POCUS evaluations were included in the initial sample (collected from July 2022 through November 2022) and 158 in the confirmatory sample (collected between August 2023 and January 2024). POCUS evaluations changed the therapeutic conduct in 57% of the assessments (95% CI 48.2‒65.2), mainly due to modification in diuretic prescription. All results were similar and confirmed in the second sample.
conclusionThis hypothesis-generating study shows that POCUS evaluations may be useful for assessing volume status in hospitalized patients and were associated with changes in reported therapeutic plans. The present findings reinforce that incorporating POCUS into their routines can potentially benefit medical education and clinical practice.
