55 Post-pandemic paediatric asthma admissions: Clinical characteristics and outcomes of children hospitalized with asthma in 2022: The READAPT-Kids study cohort
Bibliographic record
Abstract
Abstract Background Asthma exacerbations triggered by acute respiratory infections (ARIs) are a major cause of hospitalizations in children. There were large reductions in asthma admission during the SARS-CoV2 pandemic. Following the relaxation of public health interventions, there was a resurgence in admissions for ARIs. The effect of this rebound in ARIs on asthma management practices and outcomes is not well understood. Objectives To describe sociodemographic characteristics, etiology, management, and clinical outcomes of children and youth under the age of 18 years admitted to a tertiary care paediatric hospital with an acute asthma exacerbation from July 1, 2022 to Dec 31, 2022. Design/Methods An observational cohort study of children and youth less than 18 years, hospitalized with an acute asthma exacerbation from July 1, 2022 to Dec 31, 2022 at a single large Canadian children’s hospital. This was a subgroup analysis of the READAPT-Kids study cohort (Clinical chaRacteristics and outcomEs of hospitAlized children with Acute resPiratory infecTions.) Cases were identified using ICD-10-CA codes, then manually screened for inclusion. Detailed clinical and demographic information was extracted. Results Among 551 patients hospitalized with an ARI, 29.2% (n=161) were diagnosed with an asthma exacerbation. 99 were male (61.5%) with a median age of 3.8 years (IQR 2.2-6.3). 41.3% (n=64) had a previously documented asthma history, and of those, only 16.9% were taking any form of asthma therapy at admission. In hospital, 91.4% were given systemic corticosteroids, 86.5% had at least 1 viral pathogen identified, 72.2% had a chest x ray, 42.1% received antibiotics, and 23.7% had high flow nasal cannula oxygen outside of the paediatric intensive care (PICU). 22.4% (n=36), were admitted to the PICU, and 3.7% required invasive mechanical ventilation, there were no patient deaths. Median length of stay was 2.6 days (IQR 1.7–4.6 days). At discharge, 79.5% were prescribed regular inhaled corticosteroid therapy. Conclusion Asthma admissions accounted for a significant proportion of children hospitalized with ARIs in the post-pandemic era, with one fifth requiring transfer to PICU. CXR and antibiotic usage were high. Over 80% of those with a previous diagnosis of asthma were not taking inhaled corticosteroids at the time of admission.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
