Predictive value of bedside lung ultrasound, quantitative chest CT, and frailty assessment for short-term outcomes in elderly patients with severe pneumonia: a pilot study.

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
backgroundElderly patients with severe community-acquired pneumonia (CAP) have high short-term mortality, yet conventional severity scores do not incorporate bedside imaging or physiological frailty. In this study we aim to (1) evaluate the feasibility of obtaining lung ultrasound (LUS), quantitative chest computed tomography (CT), and Clinical Frailty Scale (CFS) assessments during the same admission and (2) explore the predictive potential for 28-day mortality by integrating imaging severity with physiological frailty.
methodsIn this prospective, single-center pilot study (February 2022 - February 2025), we consecutively enrolled 60 hospitalized adults ≥ 65 years who met guideline criteria for severe CAP and completed 28-day follow-up. Twelve-zone LUS and CFS assessments were performed ≤ 24 h after admission; chest CT was acquired within 48 h when clinically permissible. Feasibility outcomes were recruitment rate, data completeness, and study-related adverse events. Associations with 28-day mortality were analyzed descriptively and with exploratory multivariable logistic regression.
resultsLUS and CFS were completed in 100% and 93.3% of participants, respectively; CT was obtained in 83.3%. No study-related adverse events occurred. Twelve patients (20%) died within 28 days. Compared with survivors, non-survivors had higher median LUS scores (14.1 vs. 12.1), greater CT-defined consolidation (30% vs. 22% of lung volume), and a higher prevalence of severe frailty (58% vs. 25%). In the 50 participants with complete data, both LUS score (odds ratio [OR] 1.09 per point) and severe frailty (OR 3.85) independently predicted mortality. A model combining LUS and frailty improved discrimination relative to CURB-65 alone (area under the receiver-operating characteristic curve 0.75 vs. 0.68).
conclusionsSimultaneous acquisition of LUS, quantitative CT, and frailty metrics is feasible, safe, and well tolerated in elderly patients with severe CAP. Preliminary evidence suggests that integrating imaging severity with physiological frailty enhances short-term risk stratification beyond established clinical scores. These findings merit confirmation in larger, multicenter cohorts.
