Prescription opioid dispensing patterns among patients with schizophrenia or bipolar disorder

Patients with SZ or BD had a higher prevalence of comorbidities, including pain, versus controls in each analysis year. The proportions of individuals dispensed chronic or nonchronic opioid medications each year were similar between commercially and Medicaid-insured patients with SZ versus controls and were higher for patients with BD versus controls. From 2015 to 2019, the proportions of individuals who were dispensed prescription opioids chronically or nonchronically decreased for patients with SZ or BD and controls.
