Project Abstract: People with serious mental illness suffer substantial losses in quality of life and encounter major obstacles in role functioning. Having a serious mental illness, which often comes with comorbid somatic disorders, reduces life expectancy by 10 to 20 years. This, along with the high demands people with serious mental illness place on the healthcare system, underscores the importance of increasing our understanding of how services for this population should be organized to optimize their outcomes.


This study will assess the impact of different health care plans on the rate of avoidable hospitalizations and access to recommended preventive care for people with serious mental illness in the U.S. The impact of different service delivery models on health care usage, employment, and income-related outcomes for people with serious mental illness in the Netherlands will also be examined. Data on enrollment, plan choice and insurance claims for the New York State Medicaid population will be used, along with patient-level data from Statistics Netherlands. The results of the study will help determine how the organization of services translates to outcomes for people with serious mental illness, such that policymakers will be better informed on how to organize services for this high-need, high-cost population.
