Implementation of point-of-care ultrasound in the medical intensive care unit: A retrospective analysis of physician practices and patient outcomes.
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
backgroundPoint of care ultrasound (POCUS) use has become ubiquitous in the ICU setting. Despite this, there remains a paucity of data regarding how its use impacts patient outcomes. We sought to determine if physician attitudes toward and use of POCUS impact patient outcomes.
objectivesTo evaluate the impact of physician use of POCUS in the medical intensive care unit (MICU) on patient care outcomes.
methodsA longitudinal, single-center retrospective study of adult patients in a tertiary care center MICU was conducted between 2016 and 2017. A total of 512 patient encounters were analyzed for: number of ventilator days, number of vasopressor days, and MICU length of stay. The outcomes were then compared between attending physicians who showed high, medium, and low self-reported POCUS implementation and confidence scores by questionnaire.
resultsPatients of physicians in the low POCUS confidence group had a statistically significant increase in MICU length of stay (IRR = 1.19, 95% CI: 1.06-1.32, p = 0.0022) and ventilator days (IRR = 1.18, 95% CI: 1.03-1.36, p = 0.0197) compared to the medium confidence group.
conclusionsOur investigation found a statistically significant relationship between self-reported confidence in POCUS by MICU physicians and MICU length of stay as well as total days spent on mechanical ventilation. Increased self-reported use of POCUS by physicians did not impact patient outcomes in this population. There was similarly no evidence of increased harm or adverse outcomes in high-POCUS implementation groups.
