Association between Timing of Albuterol and Care Escalation to the
intensive care unit Among Pediatric Patients admitted with Status
Asthmaticus
Abstract
Children admitted to the ward for status asthmaticus may not receive the
first albuterol treatment on schedule. We sought to determine if a
difference in timing between scheduled and actual first dose of
albuterol is associated with care escalation to the pediatric intensive
care unit (PICU). We conducted a single-center case-control study of
children 2-18 years admitted from the emergency department (ED) to the
ward for status asthmaticus. Cases required transfer to the PICU within
24 hours of admission. Groups were compared using Fisher’s exact or
Mann-Whitney U tests. Firth multivariable logistic regression
estimated the association between dose timing and odds of transfer to
the PICU. Groups did not differ by demographics, comorbidities, or
asthma severity risk factors. The median (IQR) time difference between
scheduled and administered first dose of albuterol was 0 (-14 to 63)
minutes for cases and 16 (-6 to 42) minutes for controls ( p=.4).
Fifty percent of cases received delayed treatment compared to 63% of
controls ( p=.28). The adjusted analyses demonstrated that as the
time difference between scheduled and administered albuterol increased
by 1 minute, odds of care escalation to the PICU remained the same
(OR=1.0, 95% CI: 0.9 to 1.0; p=.2). Receiving first albuterol
treatment on the ward at a time different than scheduled was not
associated with increased odds of transfer to PICU. Delayed albuterol
administration did not vary with PICU transfer. Delays in treatment,
when taken in the context of evidence-based asthma pathways, did not
significantly impact hospital course or quality of care.
