Background: Having insurance that adequately meets health needs is a critical, but complex issue for children with special health care needs (CSHCN). Clearly defining underinsurance is vital for policymakers to fully and accurately characterize the problem. Our objectives are to identify differences in who is considered underinsured when identified by two commonly-used definitions and to discuss implications for policy decisions based on using one definition over the other.

Methods Data from the National Survey of CSHCN, 2005/06 were analyzed; only continuously-insured CSHCN were included. We identified underinsured cohorts using "economic" and "attitudinal" definitions, examining CSHCN identified by each definition, by both, and by one but not the other. Variables included demographics and condition/health characteristics.

Results Different underinsurance rates were identified [attitudinal=30.9% (n=11,470); economic=22.7% (n=8,447); both=12.6% (n=4,693); attitudinal only=19.1% (n=6,777); economic only=10.1% (n=3,754)] with only fair agreement by kappa score (0.3194; Z=65.91; p>0.0001). Differences across cohorts included family income ≥400% FPL (attitudinal only=34.2%, economic only=16.3%, both=18.4%; p<0.001) and high condition severity (attitudinal only=42.5%, economic only=68.5%, both=69.9%; p<0.001). CSHCN needing equipment, medical supplies, or home health had increased likelihood of being underinsurance by the economic definition only (1.31, p<0.01).

Conclusions: Choosing either definition excludes some potentially underinsured CSHCN, thus underestimating underinsurance. Despite overlap between definitions, there is variation in identification and among characteristics associated with the odds of being underinsured. A definition that comprehensively identifies and describes underinsurance is vital to translating health coverage expansion into benefit packages that meet complex health and service needs. Further research should focus on definition development.
