John E. "Jack" Wennberg is the pioneer and leading researcher of unwarranted variation in the healthcare industry. Through four decades of work, Wennberg has documented the geographic variation in the healthcare that patients in the United States receive. In 1988 he founded the (Center for Evaluative Clinical Services ) (CECS) at Dartmouth Medical School, which works directly with Health Dialog to address this unwarranted variation in healthcare. He currently holds the Peggy Y. Thomson Chair for the Evaluative Clinical Sciences at Dartmouth and has been Professor in the Department of Community and Family Medicine since 1980 and in the Department of Medicine since 1989. Dr. Wennberg is the founding editor of the (Dartmouth Atlas of Health Care ), a series of reports on how health care is used and distributed in the United States. In June 2007, Wennberg stepped down as director of the CECS, now known as The Dartmouth Institute for Health Policy and Clinical Practice (TDI).〔(Health Affairs Press Release: Nov. 1,, 2007 )〕 ==Biography== Wennberg is a member of the Institute of Medicine of the National Academy of Sciences and of the Johns Hopkins University Society of Scholars. Wennberg is a graduate of Stanford University and the McGill University Faculty of Medicine. His postgraduate training was in internal medicine and nephrology at Johns Hopkins, but he became interested in the application of epidemiological principles to the health care system while pursuing his master’s degree in Public Health at Johns Hopkins. He cofounded the (Informed Medical Decisions Foundation ) in Boston, Massachusetts, a nonprofit organization that provides objective scientific information to patients about their treatment choices using interactive media. Wennberg is Principal Investigator and Series Editor of ''The Dartmouth Atlas of Health Care'', which examines the patterns of medical resource intensity and utilization in the United States. The Atlas project also has reported on patterns of end-of-life care, inequities in the Medicare reimbursement system, and the underuse of preventive care.〔http://www.capconcorp.com/oba05/bios/wennberg.pdf〕 "When Jack started his work, geographic variation in health care—and the resulting variation in health care costs—was largely unknown and unremarked upon," said ''Health Affairs'' founding editor John Iglehart, who presented an award from the journal to Wennberg. "But thanks to Jack’s persistence, the idea that the care you receive is largely determined by where you live—and not necessarily by what is most appropriate for you—has become part of the common parlance of health policy." Indeed, Wennberg’s work has shown that areas that spend more and provide more services often experience worse outcomes than lower-spending areas that provide less intensive care. In a 2002 Health Affairs article, Wennberg proposed a Medicare reform plan based on reducing unwarranted regional variations in spending by the program. In the latest Dartmouth Atlas, Wennberg and colleagues state that "the Medicare system could reduce spending by at least 30 percent while improving the medical care of the most severely ill Americans." Wennberg’s recent work has focused on documenting outcomes and communicating outcomes information to patients. This focus is reflected in his article in the Nov/Dec 2007 issue of Health Affairs. In the first part of a two-part article, Wennberg and coauthors urge the Centers for Medicare and Medicaid Services (CMS) to use its pay-for-performance program to ensure that patients are both informed and empowered to choose appropriate discretionary treatments. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John Wennberg」の詳細全文を読む スポンサード リンク
