Utilization of Dysphagia Services Among Older Adults Hospitalized With Pneumonia in a Large Sample of <scp>US</scp> Hospitals
Bibliographic record
Abstract
BACKGROUND: Pneumonia is a major cause of morbidity and mortality among older adults, with increased risk for individuals with neurodegenerative conditions. Although dysphagia is a significant risk factor for pneumonia pathogenesis, there is a paucity of data on dysphagia management in patients hospitalized with pneumonia. Therefore, we examined dysphagia service utilization rates and associated clinical factors for older adults hospitalized with pneumonia. METHODS: We identified community-acquired and aspiration pneumonia (CAP and Asp-PNA) general care hospitalizations among older adults (age ≥ 60) between April 2022 and December 2023 using the Premier Healthcare Database. Factors that influenced utilization of three primary dysphagia services-clinical evaluations, instrumental evaluations (e.g., videofluoroscopy), and therapy-were examined in three generalized linear mixed models with a random effect for hospital and adjusted for patient demographics and hospital characteristics. RESULTS: Our sample included 195,782 older adults (51.7% female; 19.3% ND; 15.7% Asp-PNA) across 943 hospitals, and 23.6% received a clinical evaluation, 6.8% an instrumental evaluation, and 11.2% therapy. Generalized linear mixed models of clinical evaluations, instrumental evaluations, and therapy revealed significant associations of Asp-PNA, neurodegenerative disease (ND), and their interaction. The association between Asp-PNA and dysphagia services was greater in the non-ND group (clinical: OR = 9.57; instrumental: OR = 9.67; therapy: OR = 8.66) and attenuated in the ND group (clinical: OR = 5.49; instrumental: OR = 4.66; therapy: OR = 4.20). Similarly, the association between ND and dysphagia services was greater for those with CAP (clinical: OR = 2.85; instrumental: OR = 2.03; therapy: OR = 3.11) and dampened for Asp-PNA (clinical: OR = 1.64; instrumental: OR = 0.98; therapy: OR = 1.50). CONCLUSIONS: Dysphagia services were provided to less than one quarter of older adults with pneumonia in our large U.S. cohort, although rates were higher among patients with Asp-PNA and neurodegenerative disease. Future research should focus on using dysphagia screening tools to promote appropriate referrals to dysphagia services for pneumonia patients.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
