Nonadherence (also called noncompliance) refers to a patient’s failure to follow these recommendations, such as by not filling a medication prescription or by stopping the medication before being instructed to do so, improperly using a medical device, carrying out prescribed behaviors (e.g., specific exercises) incorrectly, or entirely ignoring medical advice (such as to avoid certain foods, or to engage in disease screening). Nonadherence can be purposeful or not. The term “unintentional nonadherence” is used to describe cases in which patients believe (mistakenly) that they are adhering to what has been prescribed, whereas “intentional nonadherence” is used for cases in which patients choose to disregard treatment recommendations completely or to modify their prescribed regimens.
