Abstract
To identify whether medical homes in FQHCs have advantages over other group and individual medical practices in caring for people with severe mental illness. Models estimated the effect of the type of medical home on monthly service utilization, medication adherence, and total Medicaid spending over a 4-year period for adults aged 18 or older with a major depressive disorder (N = 65,755), bipolar disorder (N = 19,925), or schizophrenia (N = 8501) enrolled in North Carolina’s Medicaid program. Inverse probability of treatment weights (IPTW) were used to adjust for nonrandom assignment of patients to practices. Generalized estimating equations for repeated measures were used with gamma distributions and log links for the continuous measures of medication adherence and spending, and binomial distributions with logit links for binary measures of any outpatient or any emergency department visits. Adults with major depression or bipolar disorders in FQHC medical homes had a lower probability of outpatient service use than their counterparts in individual and group practices. The probability of emergency department use, medication adherence, and total Medicaid spending were relatively similar across the three settings. This study suggests that no one type of medical practice setting—whether FQHC, other group, or individual—consistently outperforms the others in providing medical home services to people with severe mental illness.
