Suggested definitions and relationships among medication misadventures, medication errors, adverse drug events, and adverse drug reactions

Abstract

Medication misadventure: An iatrogenic hazard or incident That is an inherent risk when medication therapy is indicated. That is created through either omission or commission by the administration of a medicine or medicines during which a patient may be harmed, with effects ranging from mild discomfort to fatality. Whose outcome may or may not be independent of the preexisting pathology or disease process. That may be attributable to error (human or system, or both), immunologic response, or idiosyncratic response. That is always unexpected or undesirable to the patient and health professional. 1,2,a
