IBM Project Published in Journal of Medical Systems and Recognized by the United States House of Representatives

At the AnyLogic Conference 2014, Kyle Johnson, Global Business Services in Advanced Analytics and Optimization at IBM partnered with Otsuka Pharmaceuticals, presented a "Multi-Agent-Based Simulation of a Complex Ecosystem of Mental Health Care." To date, the research paper was published in the Journal of Medical Systems and received the attention of the United States House of Representatives [1].

The project revolves around the housing cycle of the United State's Severely and Persistently Mentally Ill (SPMI). An SPMI patient defines someone with a diagnosis of Schizophrenia, Bipolar Disorder, or Major Depressive Disorder, and this group constitutes about 1.7% of the US population. To better understand the condition and possible improvements, IBM Global Research and Otsuka Pharmaceuticals used an agent-based approach to model the SPMI living situations over the second half of the 20th century.

Agent-based modeling also allowed the researchers to capture the dynamics of individual patients, both their internal dynamics of receiving and responding to treatment and their interactions with the larger ecosystem.

Ongoing work will result in the use of care coordination information technology to help a geographic area's many health care providers work together to treat SPMI patients efficiently.
