Medical home enrollment had mixed effects on acute care use and a large effect on outpatient care use. Effects on expenditures varied by mental illness.

Preventive service use was better in patients with a usual source of care but little improved by patient-centered medical home status.

Value-based insurance design copayment reductions sustained medication adherence 2 years into policy implementation and were most effective in patients with poor adherence before policy implementation.
