Regenstrief Institute, Inc

William M. Tierney, M.D. , is the President and CEO of the Regenstrief Institute, Inc., Interim Director for the Regenstrief Center of Biomedical Informatics, and a Chancellor's Professor and Sam Regenstrief Professor for Health Services Research at the Indiana University School of Medicine where he also serves as Associate Dean for Clinical Effectiveness Research.  Dr. Tierney  is also the Chief of Medicine at Wishard Health Services.

His research focuses on implementing electronic health record systems (EHRs) in both hospital and outpatient venues in Indiana and in Kenya, where his team of developers implemented sub-Saharan Africa's first ambulatory EHR.  This system has grown to support a network of more than 50 primary care clinics with records from more than 3 million visits and 300,000 patients, and has been expanded by Regenstrief developers to become OpenMRS, the most widely implemented open-source EHR in the developing world.  Dir. Tierney helped implement one of the first computer-based provider order-entry systems in the U.S. in Wishard Health Services and has used it and other computer-based tools to enhance the quality and efficiency of health care.  Dr. Tierney is a member of the Institute of Medicine, a Master of the American College of Physicians, and a Fellow of the American College of Medical Informatics.

Health Services Research/IUCHSOR

Michael Weiner, MD, MPH, Associate Director and Research Scientist, Regenstrief Institute, Inc., is director of the Institute's Health Services Research Program as well as the IU Center for Health Services and Outcomes Research. He is also Director of the Department of Veterans Affairs Health Services Research and Development Center of Excellence on Implementing Evidence-based Practice, located at the Richard L. Roudebush VA Medical Center in Indianapolis. 

Dr. Weiner joined the IU School of Medicine faculty and the Regenstrief Institute in 1999, following undergraduate work at Brown University, medical school at Duke University, and residency and fellowship at The Johns Hopkins University. While at Hopkins, he also earned a master’s degree in public health. In 2003, Dr. Weiner was awarded the Outstanding Researcher Award from the Division of General Internal Medicine & Geriatrics, Indiana University School of Medicine.

Dr. Weiner’s professional interests are health services research, geriatrics, and health informatics. At IU Geriatrics, he founded the gero-informatics program, which under his leadership focused on leveraging health information technologies to improve the care of older adults.  His clinical and health-services research is focused on measuring and improving the quality, coordination, and delivery of health services for older adults. He also studies the effects of health information and information technology on physicians' practices and patients' outcomes. Dr. Weiner has conducted studies of specialty referral, patient-physician videoconferencing, and other forms of telecommunication to improve healthcare. Current research includes development, implementation, and study of information systems to promote clinical handoffs, management of medications, patient-centered geriatrics care, and clinical decision support.
