induced unintentionally by medical advice or treatment.
Examples of iatrogenic effects include hospital-acquired infections, incorrect treatment due to misdiagnosis, drug interactions, and consequences due to unnecessary treatment for profit. Not all iatrogenic events are harmful; some are just unintentional, such as a scar from surgery. And some, such as the side effects of some chemotherapy, are negative but are tolerated because of the potential benefits.
Etymology: 1920s, Greek, from iatros, healer, and genesis, origin.
