Chief Data Officer
Harkness Project Title: Predictive Risk Modeling: Implications for Improving Access, Quality, and Cost-Effectiveness of “Upstream” Care
Mentors: John Billings, J.D., and David Olds, Ph.D.
Placement: Robert F. Wagner Graduate School of Public Service, New York University
Biography at time of Harkness Fellowship: Geraint Hywel Lewis, M.A., M.Sc., M.B., B.Chir., M.R.C.P., M.F.P.H., a 2007–08 Commonwealth Fund Harkness Fellow in Health Care Policy and Practice, is a public health physician working as an adviser at the Cabinet Office and as a visiting fellow at the King's Fund. Lewis developed and implemented the Virtual Wards project (aimed at avoiding emergency hospital admissions), which won an unprecedented four categories at the Health Service Journal awards and is being adopted across the United Kingdom and internationally. His current interest is in novel applications of predictive risk modeling, such as predicting admissions to nursing homes and forecasting social exclusion. He has published several articles in journals such as the BMJ, The Journal of Physiology, and the Health Service Journal, and has co-authored a postgraduate textbook on public health. Lewis holds a primary medical qualification from Cambridge and a master's degree in public health from the London School of Hygiene and Tropical Medicine, as well as membership of the Royal College of Physicians of London and of the Faculty of Public Health.
Project: Lewis evaluated the current use of predictive risk modeling in the United States for targeting upstream care. He undertook more than 30 semi-structured interviews with policy-makers, academics, vendors, consultants, providers and payers. As a second project, he developed a predictive tool to estimate the capacity of individual pregnant mothers to benefit from the Nurse Family Partnership – a program of prenatal and infancy home visiting for socially disadvantaged mothers bearing first children. To develop the tool, he used longitudinal data from three randomized controlled trials of the program.
