When I was a doctoral student in health care administration at the University of Chicago, I worked with Odin Anderson, who introduced me to Osier Peterson and Bjprn Smedby. Odin first took me to Sweden in 1966. In early 1970, I met Lee Lusted and heard about clinical decision analysis. My interests, then as now, were the costs and outcomes of hospital care, although the methods I have used to address these problems have varied over time.
