Multivariate Predictive Model for Successful Medicaid or SCHIP Enrollment 90 Days After Emergency Department Intervention

	OR (95% CI)	P
Intervention	3.8 (1.7, 8.6)	.001
Age (per 5-year increment)	0.6 (0.4, 0.8)	< .001
Male gender	1.4 (0.8, 2.7)	.25
Race/ethnicity
White	0.8 (0.3, 2.1)	.66
Non-White	1.0	Reference
Any public assistance	8.6 (3.2, 23.0)	< .0001
Intervention × any public assistancea	0.2 (0.1, 0.7)	.012

Note. SCHIP = State Children’s Health Insurance Program; OR = odds ratio; CI = confidence interval. Independent variable in logistic regression model = yes/no successful SCHIP/Medicaid enrollment.Area under receiver operating characteristic curve = .76; Hosmer–Lemeshow P= .39; parent education and household income were noncontributory and thus excluded.

^a Significant interaction effect; OR[intervention] among households without ongoing public assistance = 3.7 (95% CI=1.6, 8.4); P= .002; with public assistance = 0.6 (95% CI = 0.2, 1.7); P = .33.
