RESUMEN
PURPOSE: The complexity of patients with mental healthcare needs cared for by clinical pharmacists is not well delineated. We evaluated the complexity of patients with schizophrenia, bipolar disorder, and major depressive disorder (MDD) in Veterans Affairs (VA) cared for by mental health clinical pharmacist practitioners (MH CPPs). METHODS: Patients at 42 VA sites with schizophrenia, bipolar disorder, or MDD in 2016 through 2019 were classified by MH CPP visits into those with 2 or more visits ("ongoing MH CPP care"), those with 1 visit ("consultative MH CPP care"), and those with no visits ("no MH CPP care"). Patient complexity for each condition was defined by medication regimen and service utilization. RESULTS: For schizophrenia, more patients in ongoing MH CPP care were complex than those with no MH CPP care, based on all measures examined: the number of primary medications (15.3% vs 8.1%), inpatient (13.7% vs 9.1%) and outpatient (42.6% vs 29.7%) utilization, and receipt of long-acting injectable antipsychotics (36.7% vs 25.8%) and clozapine (20.5% vs 9.5%). For bipolar disorder, more patients receiving ongoing or consultative MH CPP care were complex than those with no MH CPP care based on the number of primary medications (27.9% vs 30.5% vs 17.7%) and overlapping mood stabilizers (10.1% vs 11.6% vs 6.2%). For MDD, more patients receiving ongoing or consultative MH CPP care were complex based on the number of primary medications (36.8% vs 35.5% vs 29.2%) and augmentation of antidepressants (56.1% vs 54.4% vs 47.0%) than patients without MH CPP care. All comparisons were significant (P < 0.01). CONCLUSION: MH CPPs provide care for complex patients with schizophrenia, bipolar disorder, and MDD in VA.
