ABSTRACT
Emergency physicians are responsible for admitting children with asthma who do not respond to initial therapy. We examined the hypothesis that an initial room air pulse oximetry ≤90% elevates the risk of a complicated hospital course in children who require admission with acute asthma. METHODS: Charts of all patients ages 2â¯years-17â¯years admitted for asthma from January 2017 to December 2017 were reviewed. An explicit chart review was performed by trained data extractors using a standardized form. RESULTS: A total of 244 children meeting inclusion criteria were admitted for asthma from the ED during the study period. All patients had an initial room air pulse oximetry documented. Sixty-five were admitted to PICU status (27%), and 179 (73%) were admitted to floor status. The relative risk of a complicated course in those patients presenting with a saturation of ≤90% was 11.3 (95% CI 3.9-32.6). The mean initial pulse oximetry on patients with a complicated course was 85% versus 93% for those without a complicated course (pâ¯<â¯0.005). CONCLUSION: Our data suggest that in pediatric asthmatics that require admission from the ED, those with pulse oximetry readings less than or equal to 90% on presentation are at higher risk of a complicated hospital course.
