Division of Health Services Research
About the Division
At The Ohio State University Department of Neurology Division of Health Services Research, we are committed to efforts to optimize the health outcomes and well-being of people with neurological symptoms and disease. Our research aims to better understand health and healthcare delivery and to develop, evaluate, and implement interventions to improve both health and societal outcomes. We have experience in a variety of research methods including complex analyses of secondary data, development and evaluation of decision support tools, qualitative data acquisition and analyses, and randomized health services research clinical trials.
Welcome from the Division Co-Directors
Housed within the Ohio State Department of Neurology and CATALYST – the Center for the Advancement of Team Science, Analytics, and Systems Thinking in Health Services and Implementation Science Research – the Health Services Research Division is co-directed by Dr. Kevin A. Kerber and Dr. James Burke and supported by Research and Project Managers, data analysts, PhD researchers, and other faculty.
Jim Burke, MD, MS
Dr. Jim Burke trained in Neurology and Vascular Neurology at the University of Michigan, completed health services research training through the Robert Wood Johnson Clinical Scholars Program, and served on the faculty of UM before joining Ohio State to co-direct the HSR Neurology Division. Dr. Burke has been continuously funded by the National Institutes of Health, and his research has focused on a variety of topics including individualized treatment decisions, understanding racial disparities in stroke outcomes, and exploring how patient preferences affect health outcomes. Dr. Burke applies advanced statistical methodology to optimize diagnostic and treatment decisions for individual patients.
Dr. Burke’s research has addressed a variety of topics, such as how to best target treatment to individual patients, evaluating the value of neurologic care, understanding how end-of-life preferences influence care, understanding how race disparities emerge after stroke, and evaluating population-level outcomes of varying treatment strategies.
Kevin Kerber, MD, MS
Dr. Kerber trained in neurology at the University of Michigan and neurotology at the University of California, Los Angeles. He completed a master’s degree in Health and Healthcare Research at UM. He was on the faculty of UM before joining Ohio State to co-found the HSR Neurology. His grant funding, from the National Institutes of Health and Agency for Healthcare Research and Quality, has included projects about the clinical epidemiology of dizziness, clinical decision rule development to identify stroke in acute dizziness presentations, health services randomized clinical trials to implement evidence-based care practices in routine care emergency departments, and the development and evaluation of patient-oriented behavioral interventions. He is particularly interested in the development and management of patient-focused resources.
Dr. Kerber currently is collaborating with Kaiser Permanente Southern California on an NIH-funded clinical trial of a provider- and patient-based implementation strategy to optimize management and outcomes for ED dizziness presentations. He has also evaluated payment policies and collaborated with other investigators across a variety of topics including stroke epidemiology, geographic variation in neurologists and neurologic care, and the value of neurologic care. Dr. Kerber serves as a Vice-Chair of Clinical Operations and the Director of the Neuro-otology program.
Goals and highlights
What is health services research (HSR)?
Traditional biomedical research aims to determine what causes disease and how can it be treated or prevented.1
Health services research asks:
- How does healthcare fit into people's lives in the real world?
- How do social determinants of health come into play?
- What delivery systems are required?
- How can delivery systems be designed to meet the needs of patients and providers?
- How can we select the best treatments for individual patients?
- How do we help patients identify and follow the right treatment path, given their values and preferences?
The art of delivering healthcare is complicated. Health services research produces data, evidence, and tools to make healthcare accessible, affordable, effective, equitable, patient-centered, and safe. HSR seeks to facilitate getting the right care to the right people at the right time.
Why HSR in neurology?
- HSR methods can be applied to any subspecialty within neurology.2
- HSR questions entail collaboration across various disciplines including emergency medicine, intensive care, primary care, physical therapy, psychology, and geriatrics.
- HSR researchers pursue careers in many settings including academia; professional organizations; health policy groups; clinical settings; hospital administration; for-profit companies; and international, federal, state, and local agencies.

Fellowship opportunity
Advancement, opportunity, and collaboration describe the research and scholarship efforts in The Department of Neurology and the Health Services Research Division. Our faculty members are engaged in a broad range of multidisciplinary efforts to bolster advances in the practice, teaching, and research of family medicine. Our successes are demonstrated by professional presentations, publications, and grant support. Investigator-initiated research drives the department toward its goal of being a nationally and internationally recognized leader in research and scholarship. Educational initiatives and research continue to produce state-of-the-art curricula, teaching strategies, and learning techniques that advance medical education at many levels, including medical student education, residency training, and continuing medical education. The Ohio State University College of Medicine has as its goal to expand research in health equity, social determinants of health, population health, and health services and implementation science as well as the reduction of health inequities among our patients and communities through care delivery and education. The new faculty member will have an important role in helping the college achieve its goals. For more information and to apply, visit the Health Services Research Fellow posting.
