Iatrogenic refers to a complication or adverse result of a medical therapy or diagnostic procedure that is inadvertently induced by a physician, psychologist, therapist, or other healthcare professionals.
Iatrogenic conditions almost exclusively refer to complications or adverse effects stemming from medical treatment, while the healthcare professional is often not blamed. In fact, sometimes an individual (patient) may react atypically to a medication or diagnostic procedure when compared with the average person under similar conditions. More specifically, an individual’s genetic makeup (e.g., genetic mutations) may variably predispose them to adversely react to certain medications. Yet, these types of outcomes are labeled idiosyncratic events by some and iatrogenic conditions by others. The term iatrogenic may appear vague to some individuals in part because its interpretation can be subjective and contextually influenced.
