Abstract
Patient characteristics may influence medical decision making in various ways. The contribution of several patient characteristics to medical decision making was studied. Thirty oncologists, 29 nursing home physicians, and 22 cardiologistswere interviewed (overall response = 60%). Respondents were asked whether they would apply a specified intervention for a number of hypothetical seriously ill patients, who varied with respect to factors thatwere not relevant to the outcome of treatment. The condition that made patients clearly eligible for treatment was kept constant. In amultivariate regression model, patients with a better physical condition, a more obvious social role, and a lower age weremore likely to be treated thanwere other patients. Medical decision making is not exclusively based on empirical evidence but also related to morally complex issues such as patient age and social status.
