• This is a Healthcare Effectiveness & Data Information Set (HEDIS®) administrative measure and only includes Medicaid Primary beneficiaries.
• The annual reported rate captures activity during the stated measurement year (MY).

This measure assesses the percentage of members with schizophrenia who were 18 years of age and older during the measurement year and were dispensed and remained on antipsychotic medication for at least 80% of the treatment period.

For people with schizophrenia, nonadherence to treatment with antipsychotics is common, and medication nonadherence is a significant cause of relapse.  Measuring antipsychotic medication adherence may lead to less relapse and fewer hospitalizations.  Additionally, there is potential to lead to interventions to improve adherence and help close the gap in care between people with schizophrenia and the general population.
