Assessing the clinical relevance of point-of-care ultrasound for hospitalists: Influence on clinical reasoning and decision-making.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionPoint-of-care ultrasonography (POCUS) is increasingly recognized in internal medicine, yet its influence on hospitalists' clinical reasoning remains underexplored.
objectivesThis study aimed to evaluate the influence of POCUS on diagnostic hypotheses, management strategies, and confidence levels among hospitalists in a transitional care unit with limited access to advanced imaging.
methodsProspective descriptive study in a transitional care unit enrolling 19 hospitalists. During routine care, clinicians used POCUS at their discretion and, immediately afterward, completed a structured form capturing the clinical question, pre- and post-POCUS diagnostic hypotheses, confidence levels, and management decisions. Per-encounter changes in these parameters were summarized descriptively.
resultsPOCUS led to a change in the primary diagnostic hypothesis in 37% (38/104) of clinical encounters and altered management in 39% (41/104) of cases. Diagnostic confidence increased in 46% (48/104) of instances. Even when the primary hypothesis remained unchanged (62% - 66/104), POCUS strengthened diagnostic confidence in 36% (24/66) of these cases and aided in ruling out alternative diagnoses in 62% (41/66). Notably, POCUS had no discernible influence in only 13% (14/104) of cases.
conclusionThis study suggests that POCUS may influence clinical reasoning and decision-making among hospitalists in a setting with limited imaging resources. POCUS frequently led to changes in diagnostic hypotheses and management plans, and often increased diagnostic confidence, even when the initial hypothesis was maintained. These findings suggest that POCUS may play a supportive role in bedside assessment and patient management in internal medicine, underscoring the need for further research and structured training before broader integration.
