Background: Despite the significant burden of childhood asthma, little is known about prevention-oriented management before and after hospitalizations for asthma exacerbation.
Objective: To investigate the proportion and characteristics of children admitted to the intensive care unit (ICU) for asthma exacerbation and the frequency of guideline-recommended outpatient management before and after the hospitalization.
Methods: A 14-center medical record review study of children aged 2 to 17 years hospitalized for asthma exacerbation during 2012-2013. Primary outcome was admission to the ICU; secondary outcomes were 2 preventive factors: inhaled corticosteroid (ICS) use and evaluation by asthma specialists in the pre- and posthospitalization periods.
Results: Among 385 children hospitalized for asthma, 130 (34%) were admitted to the ICU. Risk factors for ICU admission were female sex, having public insurance, a marker of chronic asthma severity (ICS use), and no prior evaluation by an asthma specialist. Among children with ICU admission, guideline-recommended outpatient management was suboptimal (eg, 65% were taking ICSs at the time of index hospitalization, and 19% had evidence of a prior evaluation by specialist). At hospital discharge, among children with ICU admission who had not previously used controller medications, 85% were prescribed ICSs. Furthermore, 62% of all children with ICU admission were referred to an asthma specialist during the 3-month posthospitalization period.
Conclusion: In this multicenter study of US children hospitalized with asthma exacerbation, one-third of children were admitted to the ICU. In this high-risk group, we observed suboptimal pre- and posthospitalization asthma care. These findings underscore the importance of continued efforts to improve prevention-oriented asthma care at all clinical encounters.
