Objective: The aim of this study was to quantify the costs and resource utilization associated with a relapse of schizophrenia or schizoaffective disorder.
Methods: The study comprised a retrospective audit of data from 200 patients diagnosed with schizophrenia or schizoaffective disorder who were admitted to hospital for a relapse of their disorder in two mental health services in Australia between 1 June 2001 and 31 May 2002. Resource use and costing data were collected for 12 months before and 12 months after the hospitalization.
Results: There was an increase in contacts per month and associated outpatient costs after the index admission which persisted for the full 12 month data collection period (total of AUD $637). There was also a total increase in hospital costs but this did not persist beyond the first 2 months of the follow-up period and is likely explained by the index admission.
Conclusions: Increased healthcare resource utilization and costs results from relapse in patients with schizophrenia or schizoaffective disorder. An increase in service use and costs persist for a considerable time period after an episode of relapse.
