Probability of any additional service within 90 days by type of first service (N=36,887)

	Age 18–59 (N=32,949)		Age 60+ (N=3,938)		P-Value
Type of First Service	Mean Percentage	SE	Mean Percentage	SE
Outpatient	90.2	.2	79.7	1.1	<.001
Inpatient	60.4	1.2	41.5	3.5	<.001
EPU	42.2	.4	32.0	1.6	<.001
PERT	21.2	.7	19.1	1.0	.092

Note: Percentages are predicted probabilities and are adjusted for gender, race/ethnicity, preferred language for services, clinical diagnosis, substance use disorder diagnosis, and insurance coverage. Standardized estimates are calculated using the non-parametric bootstrap. P-values are calculated from the resulting empirical distributions.
