Fixing this will require a new kind of leader who can organize doctors into teams, measure their performance not by how much they do but by how their patients fare, deftly apply financial and behavioral incentives, improve processes, and dismantle dysfunctional cultures. Drawing on examples from best-practice institutions such as the Cleveland Clinic, Seattle’s Virginia Mason Medical Center, Intermountain Healthcare in Utah, and his own organization, Partners HealthCare System of Boston, Lee shows how a “new breed of leader” is orienting strategy around patients’ needs (a more radical idea than it might sound) and raising the quality, efficiency, and value of care.
