ACKNOWLEDGEMENTS We gratefully acknowledge the guidance, support and patience of our faculty advisor, Professor Mark Peterson. This report could not have been produced without his assistance. We are indebted to our peer reviewers, Joanna Farrer and Galena Kolchugina, for their many constructive comments on far less readable drafts of this report. We wish to express our appreciation to Professor Arleen Leibowitz for her advice and direction early in this process. Special thanks also to Professor Gerald Kominski for introducing us to cost-effectiveness analysis in health and medicine, and Dr. Richard Brown for providing us with a semester of background information on Medi-Cal in a single twenty minute discussion. Finally, we are especially grateful to Dr. David Ganz for his painstaking review of our Markov models, and his invaluable insight and advice on every aspect of this report.
