Physician David Meltzer of the University of Chicago talks about the power of the doctor-patient relationship with EconTalk host Russ Roberts. Meltzer, who also has a Ph.D. in economics, discusses a controlled experiment he has been running to measure the importance of maintaining the continuity of doctor-patient relationships. Meltzer argues that the increasing use of hospitalists--specialists who take over a patient from the patient's regular doctor once the patient is hospitalized--has raised costs and hurt patients. The initial results from his study show that patients who stay with their doctors have fewer subsequent hospitalizations and have better mental health. The conversation closes with a discussion of the challenges facing the current medical system to adopt cost-saving or life-improving technology or techniques.
