Connected Care: improving outcomes for adults with serious mental illness.

OBJECTIVES: To evaluate the effectiveness of Connected Care-a care coordination effort of physical and behavioral health managed care partners in Pennsylvania-on acute service use among adult Medicaid beneficiaries with serious mental illness (SMI).

STUDY DESIGN: We examined changes in service utilization using a difference-in-differences model, comparing study group with a comparison group, and conducted key informant interviews to better understand aspects of program implementation.

METHODS: We compared the difference in service use rates between baseline year and 2-year intervention period for the Connected Care group (n = 8633) with the difference in rates for the comparison group (n = 10,514), confirming results using a regression adjustment.

RESULTS: Mental health hospitalizations (per 1000 members per month) decreased for the Connected Care group from 41.1 to 39.6, while increasing for the comparison group from 33.8 to 37.2 (P = .04). All-cause readmissions within 30 days decreased nearly 10% for Connected Care while increasing slightly for the comparison group (P < .01), with a similar pattern observed for 60- and 90-day all-cause readmissions. No differences were observed in physical health hospitalizations, drug and alcohol admissions, or ED use. Data from qualitative stakeholder interviews illuminated facilitators and barriers of implementing Connected Care.

CONCLUSIONS: Payer-level healthcare information sharing can help identify members who could benefit from care coordination services, inform care management activities, and assist with pharmacy management. Results can inform state, health plan, and provider efforts around integration of care for individuals with SMI and improve care efficiencies and quality, which is especially important in this time of Medicaid expansion.
