The study is based on data contained in the 2006-2007 MarketScan(R) Commercial Claims and Encounters Database. The Thomson Reuters Medical Episode Grouper was used to group each enrollee's claims into distinct episodes of care based on the disease for which treatment was received.
"Medication use and behavioral characteristics are known to increase the risk of disease among bipolar patients, but much is still unknown about the reasons for increased rates of comorbidities among this population and ways to reduce them," said William D. Marder, Ph.D., senior vice president and general manager for the Healthcare & Science business of Thomson Reuters and one of the study's authors. "Our analysis underscores the urgent need for further exploration of how to best increase providers' capacity to address, monitor and ultimately improve the psychiatric and physical health of their bipolar patients."
