Adherence to Antipsychotic Medications for People with Schizophrenia

This HEDIS Measure

Assesses adults 19–64 years of age who have schizophrenia and were dispensed and remained on an antipsychotic medication for at least 80 percent of their treatment period.

So What?

Schizophrenia is a chronic and disabling psychiatric disorder that requires ongoing treatment and monitoring. Symptoms include hallucinations, illogical thinking, memory impairment, and incoherent speech.1 Medication non-adherence is common and a major concern in the treatment of schizophrenia. Using antipsychotic medications as prescribed reduces the risk of relapse or hospitalization.2
