Assessing the prevalence and the underdiagnosis of aspiration pneumonia among older hospitalized patients with community-acquired pneumonia using an artificial intelligence algorithm.

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
introductionAspiration pneumonia (AP) in older persons is associated with oropharyngeal dysphagia (OD) and is estimated to account for 5-15% of cases of community-acquired pneumonia (CAP). Artificial Intelligence Massive Screening for OD (AIMS-OD) is an algorithm for identifying OD in older patients on hospital admission using data from electronic health records (EHR). We aimed to assess the prevalence of OD among older patients hospitalized with pneumonia and thus estimate the underdiagnosis of AP based on AIMS-OD. MATERIALS AND
methodsA retrospective observational study included 15,603 patients older than 65 years who were admitted for pneumonia to a general hospital between 2013 and 2022. Clinical data were obtained from EHR. AIMS-OD is an accurate diagnostic algorithm (AUCROC > 0.79, specificity 0.92, PPV 0.86, NPV 0.58) for OD using AI and machine learning.
resultsa) AP prevalence following traditional clinical practice (ICD-10 J69.0, AP codification) on discharge was 15.57% (n=2,430, 86.73±7.43 years); b) Estimated AP prevalence related to OD identified with AIMS-OD, was 25.32% (n=3,951, 85.11±8.78 years); c) AIMS-OD identified 84.77% (n=2,060, 87.17±7.09 years) of clinically diagnosed patients (ICD-10 J69.0), and 1,891 additional cases of AP (82.87±9.84 years) undetected by clinical practice, distinguishing them from pneumonia patients without OD in seconds.
conclusionThe prevalence of AP following traditional clinical practice among older patients hospitalized with pneumonia was 15.57%. AIMS-OD revealed a potential prevalence of AP of 25.32%. AIMS-OD allows to increase by 62.6% the detection of AP related to OD versus traditional clinical practice among older patients hospitalized with pneumonia. AIMS-OD allows massive, immediate, and accurate identification of OD on hospital admission, from which AP cases can be identified, enabling early and specific treatment to improve the poor clinical outcomes of these unrecognized patients with AP and prevent its recurrence.
