COVID Croup: Pediatric Croup Due to Severe Acute Respiratory Syndrome Coronavirus 2 Infection (SARS-CoV-2; Covid-19)
Bibliographic record
Abstract
Importance During the COVID-19 [severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)] pandemic, reports emerged of croup secondary to SARS-CoV-2 in the pediatric population. Children with croup and concurrent SARS-CoV-2 infection seemed to require a greater number of doses of dexamethasone and nebulized epinephrine and were more likely to need hospitalization and intensive care unit (ICU) admission compared to pre-SARS-CoV-2 croup. Objective This study aimed to compare the outcomes of children presenting with SARS-CoV-2-associated croup and those with conventional croup. Design Observational, retrospective review. Setting Tertiary care pediatric hospital. Participants Children (age <18 years) presenting with croup between January 2019 and February 2022. Exposure SARS-CoV-2 Main outcome measure Number of doses of dexamethasone and nebulized epinephrine, need for hospital admission, ICU admission, assisted ventilation, and length of stay. Results Two thousand and three hundred ninety-eight children [68.2% male, median (interquartile range) age 25 months (15-42 months)] were included. Twenty-seven patients (1.1%) tested positive for SARS-CoV-2, 467 (19.5%) tested negative for SARS-CoV-2, and 1904 (79.4%) were not tested for SARS-CoV-2. Dexamethasone was given to 27 (100%) SARS-CoV-2-positive and 457 (98%) SARS-CoV-2-negative patients at an average of 1.4 (±1.2) and 1.1 (±1.0) doses, respectively. SARS-CoV-2-positive patients were more likely to require nebulized epinephrine (41%) compared to SARS-CoV-2-negative (12%, OR: 4.2; 95% CI 1.8-9.6, P < .001) patients, and were more often admitted (30%) to hospital than SARS-CoV-2-negative (3.4%) patients (OR: 12; 95% CI 4.4-37.7, P < .001). ICU admission was required for 3 SARS-CoV-2-negative patients, but none of the SARS-CoV-2-positive patients. Length of stay was similar across groups. Conclusion Patients with croup and SARS-CoV-2 infection were found to have an increased need for nebulized epinephrine and an increased frequency of admission to the hospital. However, there was no increased need for ICU admission or longer length of stay in the hospital. Level of Evidence III.

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.
