This article presents an historical overview of the changing meaning of the patient-consumer, and specifically the role played by patient groups in constructing the patient as consumer. It is argued that patient groups were central to the formation of the patient-consumer, but as health consumerism was taken on by the state, they lost control of this figure. Competing understandings of what it meant to be a patient-consumer developed, a shift that raises further questions about the unity of claims made in the name of the patient-consumer.
