New York Times columnist Pauline M. Chen, MD, interviews Francois de Brantes, a nationally known advocate of healthcare quality, about Brantes' proposal for a new healthcare reimbursement model that comes with a warranty. The model, called Prometheus Payment, first offers set fees to providers that cover all recommended services, treatments, and procedures for specific conditions but are also risk-adjusted for patients who may be older or frail. The warranty is based on the costs incurred by avoidable complications.
