Abstract
OBJECTIVE: Physicians providing emergency department care to children primarily use nebulizers for the delivery of bronchodilators and these physicians have misconceptions regarding the advantages and disadvantages of using metered-dose inhalers (MDIs) with a spacer (MDI + S) for acute asthma exacerbations. DESIGN: Self-administered mail survey. SETTING: Emergency department. PARTICIPANTS: Emergency medicine section members of the American Academy of Pediatrics and Canadian Pediatric Society. INTERVENTIONS: Bronchodilator delivery methods in acute pediatric asthma. MAIN OUTCOME MEASURES: The 2 principal outcomes for bivariate analysis were self-reported nebulizer use in all patients and MDI + S use in patients with mild acute asthma. RESULTS: Of eligible physicians, 333 (51%) of 567 responded. The majority were dual trained in pediatrics and pediatric emergency medicine (72%) and practiced full time (83%) in an urban (83%) pediatric emergency department (80%). The most commonly cited advantages of MDIs were their cost (33%) and speed of use (28%). The most commonly cited disadvantages were patient or parent dissatisfaction (24%) and relative ease of nebulizer use (23%). Only 10% to 21% of participants used MDIs in the emergency department and reserved this delivery method for children with mild asthma exacerbations. There were no significant associations between selected respondent demographic variables and the use of MDIs. CONCLUSIONS: Misconceptions regarding the efficacy and safety of MDI + S for the treatment of acute asthma exacerbations exist but are limited to a minority of surveyed emergency medicine physicians caring for children. Nebulizers remain the preferred method of routine bronchodilator delivery by physicians providing care to pediatric asthmatics in the emergency department.

How this classification was reachedexpand
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.
