Cost-effectiveness of current and optimal treatment for schizophrenia

Abstract

BackgroundThis paper is part of a project to identify the proportion of the burden of each mental disorder averted by current and optimal interventions, and the cost-effectiveness of both.AimsTo use epidemiological data on schizophrenia to model the cost-effectiveness of current and optimal treatment.MethodCalculate the burden of schizophrenia in the years lived with disability (YLD) component of disability-adjusted life-years lost, the proportion averted by current interventions, the proportion that could be averted by optimal treatment and the cost-effectiveness of both.ResultsCurrent interventions avert some 13% of the burden, whereas 22% could be averted by optimal treatment. Current interventions cost about AUS$200 000 per YLD averted, whereas optimal treatment at a similar cost could increase the number of YLDs averted by two-thirds. Even so, the majority of the burden of schizophrenia remains unavertable.ConclusionsOptimal treatment is affordable within the present budget and should be implemented.
