Cost Effectiveness of Clozapine and Risperidone in
Abstract
OBJECTIVES
Risperidone and clozapine beling to a new generation of antipsychotics that are reportedly more effective and better tolerated than conventional neuroleptics. However, each of these agents costs far more per unit than conventional neuroletics. The purpose of our retrospective study was to ascertain the total cost and effectiveness of treatment before and after administration of risperidone and clozapine in 'revolving door' schizophrenia patients. METHOD: Data collected on revolving door schizophrenics for 2 years before clozapine and risperidone treatment and for at least 2 years after clozapine and risperidone treatment. Direct cost of inpatient and outpatient treatment was measured. Effectiveness was scaled as 'years of mild disability gained'. RESULT: Both risperidone and cloazpine result in higher costs and additional benefits to patients, for example, increased mild disability, reduced number of relapse, and reduced hospital length-of-stay. An ICER of risperidone was less than Rc and ICER of clozapine was greater than Rc. According to decision-analytic this model, risperidone had favorable cost-effectivenss ratios relative to clozapine.
CONCLUSION
We have assumed that risperidone is more cost-effective than clozapine.
