Biography
Marc N. Elliott (Ph.D., Statistics, Rice University) is a Senior Statistician in RAND Health. His statistical areas of interest and experience include survey sampling, experimental design, causal inference, and case-mix adjustment (CMA). His substantive areas of interest and experience include consumer experiences with health care, profiling of health care institutions, health disparities, Medicare, vulnerable populations, adolescent health, mental health, and media effects on health behavior. He is the principal investigator of the CMS Medicare CAHPS® (Consumer Assessment of Health Providers and Systems) Analysis project, assessing the experience of 400,000 surveyed beneficiaries annually with their health care and examining these experiences as functions of insurance type, geography, and beneficiary characteristics. He leads a subcontract investigating mode effects, case-mix adjustment CMA, and substantive aspects of the CAHPS Hospital Survey. Since 1996, he has been RAND's lead statistician on the AHRQ CAHPS I-III projects. He leads an Office of Minority Health project developing novel, cost-effective sampling and analytic methods to improve national health estimates for small racial/ethnic subgroups. As theRAND/UCLA CDC Center for Adolescent Health Promotion's Center Statistician, Elliott provides cross-site leadership of design/analytic work on the multi-site CDC Healthy Passages study, a longitudinal study of over 5000 fifth-grade children. Elliott, a summa cum laude graduate of Rice University and a member of the American Statistical Association, has published more than 150 articles in a range of journals, including JAMA, NEJM, BMJ, JGIM, AJPH, Health Services Research, Medical Care, Pediatrics, Public Opinion Quarterly, Statistics in Medicine, Survey Methodology, and Chance.
