“Iatrogenesis” is the word for all of it. From the Greek—iatros (healer) + genesis (origin)—iatrogenesis refers to the phenomenon by which a healer harms a patient in the course of treatment. Most often, it is not malpractice, though it can be. Much of iatrogenesis occurs not because a doctor is malicious or incompetent but because treatment exposes a patient to exogenous risks. Iatrogenesis is everywhere—because all interventions carry risk. When a sick patient submits to treatment, the risks are typically worth it. When a well patient does, on the other hand, the risks often outweigh the potential for further improvement.
