Expenditures for treating schizophrenia: a population-based study of Georgia Medicaid recipients

The study analyzed all claims data for reimbursable medical services and drugs rendered to 18- to 50-year-old Medicaid recipients in the State of Georgia over a 3-year period. A cohort of 6,443 schizophrenia patients were identified by inspecting the medical history data for claims indicative of schizophrenia (ICD-9-CM 295.xx). A crude prevalence of 6.02 percent was identified. Use patterns and charges associated with schizophrenia were stratified by major areas of service including ambulatory services, hospitalizations, and pharmacological treatment. The incidence of rehospitalization for chronic schizophrenia patients based on a 12-month hospitalization index format was also identified. Findings are discussed regarding using these data to focus strategies for assessing schizophrenia treatment outcome in relation to treatment cost.
