Abstract

Background: Gaps in health insurance coverage may complicate asthma management and increase emergency department (ED) use. Using two nationally-representative surveys, we characterize the prevalence of coverage gaps among children with asthma, and describe their association with ED visits in this population. Methods: De-identified data were obtained from the 2016 National Survey of Children’s Health (NSCH) and National Health Interview Survey (NHIS). Among children with asthma, we classified coverage over the past year as: (1) continuous private, (2) continuous public, (3) gap in coverage, and (4) continuously uninsured. The primary outcome was all-cause ED visits in the past year (both surveys). Secondary outcomes included unmet health care needs (NSCH), asthma-related ED visits or hospitalizations (NHIS) and asthma exacerbations (NHIS). Results: The analysis included 3739 (NSCH) and 854 (NHIS) children with asthma, representing a population of 5.5 million children in the US. Estimated prevalence of coverage gaps was 5% in the NSCH and 3% in the NHIS. On multivariable ordinal logistic regression using NSCH data, coverage gaps were associated with increased all-cause ED use (OR = 2.5; 95% CI: 1.3, 4.7, p = 0.005), compared to continuous private coverage. Further analysis confirmed higher odds of unmet health care needs, asthma exacerbations, and asthma-related ED visits among children with coverage gaps. Conclusions: Children with asthma who experience insurance coverage gaps have increased ED use, possibly related to poorer access to appropriate health care. Protecting insurance coverage continuity may reduce ED use and improve clinical outcomes in this population.
