Abstract

Objective: Hospital-based data reveal that children who have secondhand smoke exposure (SHSe) experience severe respiratory illnesses and greater resource utilization. Our objective was to assess the relationship between SHSe and illness severity/resource utilization among children presenting to the pediatric emergency department (PED) with three common respiratory conditions-asthma, bronchiolitis, and pneumonia.

Methods: A retrospective review of a yearlong consecutive sample of PED patients with SHSe status documentation and asthma, bronchiolitis, or pneumonia diagnoses was performed. PED illness severity/resource utilization variables included triage categorization, initial oxygen saturation, evaluation/testing (influenza A & B, respiratory syncytial virus, chest X-ray), procedures/interventions performed (supplemental oxygen, suctioning, intubation), medications administered, and disposition. Logistic and linear regression models were conducted to determine differences in each diagnosis group while controlling for sociodemographics, medical history, seasonality, and insurance type.

Results: There were 3,229 children with documentation of SHSe status and an asthma (41%), bronchiolitis (36%), or pneumonia (23%) diagnosis. Across diagnosis groups, approximately 1/4 had positive documentation of SHSe. Asthmatic children with SHSe were more likely to receive corticosteroids (odds ratio (OR) = 1.71, 95% confidence interval (CI) = 1.19, 2.44) and/or magnesium sulfate (OR = 1.66, 95% CI = 1.14, 2.40). Children with SHSe and bronchiolitis were more likely to receive racemic epinephrine (OR = 2.48, 95% CI = 1.21, 5.08), have a chest X-ray (OR = 1.36, 95% CI = 1.00, 1.85), and/or be admitted (OR = 1.46, 95% CI = 1.09, 1.95). No differences in illness severity/resource utilization were identified for children with pneumonia.

Conclusions: SHS-exposed children with asthma or bronchiolitis have greater illness severity/resource utilization. Our findings highlight the importance of SHSe assessment, cessation, and research efforts in the PED setting.
