Mental health care provision in community health centers and hospital emergency department utilization.

OBJECTIVES

To examine whether community health centers (CHCs) are effective in offsetting mental health emergency department (ED) visits.

DATA SOURCES AND STUDY SETTING

The HRSA Uniform Data System and the HCUP State ED Databases for Florida patients during 2012-2019.

STUDY DESIGN

We identified CHC-year-specific service areas using patient origin zip codes. We then estimated panel data models for number of ED mental health visits per capita in a CHC's service area. Models measured CHC mental health utilization as number of visits, unique patients, and intensity (visits per patient).

PRINCIPAL FINDINGS

CHC mental health utilization increased approximately 100% during 2012-2019. Increased CHC mental health provision was associated with small reductions in ED mental health utilization. An annual increase of 1000 CHC mental health care visits (5%) was associated with 0.44% fewer ED mental health care visits (p = 0.153), and an increase of 1000 CHC mental health care patients (15%) with 1.9% fewer ED mental health care visits (p = 0.123). An increase of 1 annual mental health visit per patient was associated with 16% fewer ED mental health care visits (p = 0.011).

CONCLUSIONS

Results suggest that mental health provision in CHCs may reduce reliance on hospital EDs, albeit minimally. Policies that promote alignment of services between CHCs and local hospitals may accelerate this effect.
