Dr. Bach’s main research interests cover healthcare policy, particularly as relates to Medicare, racial disparities in cancer care quality, and lung cancer epidemiology. His research examining quality of care for Medicare beneficiaries has demonstrated that blacks do not receive as high quality care as whites when diagnosed with lung cancer, and that the aptitude and resources of primary care physicians who treat blacks are inferior, when compared to primary care physicians who primarily treat whites. In 2007 he was the senior author on a study demonstrating that care in Medicare is highly fragmented, with the average beneficiary seeing multiple primary care physicians and specialists. His work in lung cancer epidemiology 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. His healthcare policy analysis includes investigations into Medicare’s approaches to cancer payment, as well as developing models of alternative reimbursement, payment systems, and coverage policies. He is funded by grants from the National Institute of Aging, a contract from the NCI, and philanthropic sources. He formerly served as a Senior Adviser to the Administrator of the Centers for Medicare and Medicaid Services. He serves on several national committees, including the Institute of Medicine’s National Cancer Policy Forum, and the Committee on Performance Measurement of the National Committee on 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 new outlets, including the New York Times, the Wall Street Journal, Forbes Online and National Public Radio.
