Mauskopf J, Muroff M, Gibson PJ, Grainger DL. Estimating the costs and benefits of new drug therapies: atypical antipsychotic drugs for schizophrenia. Schizophr Bull. 2002 Jan 1;28(4):619-35.

This article presents an analytic tool populated with data from published studies to illustrate the likely impacts of a switch from typical to atypical antipsychotic drugs over a 3-year period on individual, family, and societal outcomes for a U.S. schizophrenia population. Data taken from clinical trials and observational data studies are used. Changes in annual health care costs, schizophrenia symptom days, extrapyramidal symptom (EPS) days, suicide rates, and employment days are estimated. For each 1,000 people treated with typical drugs, the base case scenario gives estimates of annual medical care costs of dollar 28.9 million with 80,253 moderate/severe schizophrenia symptom days and 92,006 EPS days. In the base case scenario, after switching to atypical drugs, schizophrenia symptom days are estimated to decrease up to 33 percent, EPS days up to 50 percent, and total medical care costs up to 19 percent over the 3-year period. Suicide rates fall and employment rates increase. The direction of the impacts remain the same for a wide range of input parameter values used in sensitivity analyses. Thus, switching to atypical drugs will likely reduce total medical care costs and decrease other disease burdens for people with schizophrenia, their families, and society.
