Dr. Bach’s main research interests cover health care policy, racial disparities in cancer care quality, and lung cancer epidemiology. His research examining quality of care for Medicare beneficiaries has demonstrated that black patients do not receive as high-quality care as white patients when diagnosed with lung cancer, and that the aptitude and resources of primary care physicians who treat black patients are inferior when compared to primary care physicians who primarily treat white patients. In lung cancer epidemiology, Dr. Bach has focused on the development and utilization of lung cancer prediction models that can be used to determine what lung cancer events populations of elderly smokers will experience over a period of time. He has also led multiple guideline processes on lung cancer screening. His health care policy analysis includes investigations into Medicare’s approaches to cancer payment, as well as developing models of alternative reimbursement and coverage policies. He formerly served as a Senior Advisor to the Administrator of the Centers for Medicare and Medicaid Services and currently serves on several national committees, including the Institute of Medicine’s National Cancer Policy Forum and Board on Health Care Services, as well as the Committee on Performance Measurement of the National Committee for Quality Assurance. He chairs the Technical Expert Panel that is developing measures of cancer care quality for CMS. Along with publishing in the medical literature, Dr. Bach’s opinion pieces have appeared in numerous lay news outlets, including the New York Times, the Wall Street Journal, Forbes Online, and National Public Radio.
