Researchers from Rutgers and other universities have developed a behavioral model that explains a long-standing healthcare mystery: Why do so many terminally ill patients undergo intense last-ditch treatments with little chance of meaningful life extension?

Surveys repeatedly indicate that nearly all people would rather die peacefully at home, yet painful, long-shot treatments remain common, and efforts to reduce usage have failed.

Previous analyses have mostly emphasized patients’ treatment preferences at the end of life. The new model, which its creators named the Transtheoretical Model of Irrational Biomedical Exuberance (TRIBE), focuses squarely on clinician psychology and family dynamics.

“Old models tended to assume that clinicians were purely rational agents, leading patients toward logical choices,” said Paul R. Duberstein, lead author of the study and chair of the Department of Health Behavior, Society and Policy at the Rutgers School of Public Health. “Once doctors have recommended a treatment or procedure, there’s enormous pressure on patients to undergo it.”
