Changes in Mental Health Treatment Costs Associated With CCM Implementation

Cost Drivers	Postperiod Costs		Changes in Costs
	All CCM-enhanced Sites*	Per Patient†	Per Patient‡	P	Overall§
Labor costs ($)
Internal facilitator	114,743	21	21	—	114,743
External facilitator	105,621	19	19	—	105,621
Outpatient mental health costs ($)	20,014,100	3634	50	0.455	273,257
Inpatient mental health costs ($)	2,926,957	531	(167)	0.031	(921,211)
		Total ($):	(78)	—	(427,590)
		Savings (%)∥:	−1.86	—	−1.86

Numbers in parentheses indicate savings, while other numbers indicate costs.

^*Total costs for mental health outpatient visits, inpatient stays, and personnel for CCM-enhanced teams.

^†Total costs divided by the number of patients served by CCM-enhanced teams (N = 5507) to calculate per-patient costs.

^‡DID estimates for the pre/post changes in costs associated with CCM implementation.

^§DID estimates multiplied by the total number of patients in CCM-enhanced teams.

^∥Percent savings calculated as the estimated changes in cost associated with CCM implementation divided by total postperiod costs among patients treated by CCM-enhanced teams.

CCM indicates Collaborative Chronic Care Model; DID, difference-in-difference.
