This report benefitted immeasurably from the contributions of many individuals at Mathematica Policy Research, Inc. (MPR). Marilyn Ellwood, Sue Dodds, and Mei-Ling Mason shared their vast knowledge of Medicaid data and the intricacies of the State Medicaid Research Files (SMRF). Keith Rathbun led a team of programmers in extracting the data from the SMRF files, while Terry Nguyen and Wendy Coupe helped in developing health status and utilization variables for the analysis. Embry Howell reviewed the reports and provided helpful suggestions to refine the analysis. Patricia Ciaccio, Roy Grisham, and Loriann Fell edited the report, often under tight time pressure, and we appreciate their good humor and attention to detail. We also thank Besaida Rosado for her tireless efforts in producing the text and tables in this report.
Our project officer, Laura Radel, of the Office of the Assistant Secretary for Planning and Evaluation (ASPE), provided significant insights about our findings and their implications for policy makers and practitioners. She also facilitated the acquisition of data from the Health Care Financing Administration (HCFA) for this project. We appreciate her patience and support. We also thank the ASPE, HCFA, and ACF staff who reviewed a draft of this report. Our report greatly benefitted from their effort.
