Analysis of our health care system has shown that health care spending is overwhelmingly concentrated within a very small proportion of the population. Can research focused on high health care expenditures be relevant for public health practice? We explore this issue in detail by using several linked data sources to investigate a broad range of demographic, social, behavioral, and clinical determinants associated with increased health care utilization. We will present the preliminary results from this program of research. These findings have the potential to inform policies for health care and public health and more generally support the common goal of improving population health outcomes.

Presenters: Dr. Laura Rosella and Christopher Stone

Dr. Laura Rosella is a scientist at PHO, an assistant professor, Epidemiology Division, Dalla Lana School of Public Health, University of Toronto, and an adjunct scientist at the Institute for Clinical Evaluative Sciences (ICES). As a population health researcher, she focuses on the development, validation, and application of novel epidemiologic methods to inform the prevention of chronic diseases. Recently, her research has focused on developing methods and tools to calculate the attributable health care and cost impact of various prevention strategies.

Christopher Stone is a third-year medical student at the University of Toronto and a student in the LEAD program. He worked with both Laura and Dr. Vivek Goel throughout the last year to characterize the health care utilization patterns of high users, and synthesize evidence on how physicians can incorporate public health methodology into practice to treat patients with complex needs. He is currently interested in pursuing a career in primary care and hopes to contribute to health system improvements in the future.
