Defined Study Activity

Definition 1

An activity that frequently occurs in studies (e.g. more than one time in more than one arm) and therefore is called out as a reusable template in a global library of activities outside the context of any particular study, and may be used in the composition of a defined study subject activity group. A defined activity is a "kind of" activity rather than an "instance of" an activity. (NCI Thesaurus)

Definition 2

An activity that frequently occurs in studies (e.g. more than one time in more than one arm) and therefore is called out as a reusable template in a global library of activities outside the context of any particular study, and may be used in the composition of a defined study subject activity group. A defined activity is a "kind of" activity rather than an "instance of" an activity. EXAMPLE(S): Standard blood chemistries are frequently included in studies - also activities that are study-specific and recur more than one time in more than one arm may be defined, such as a substance administration activity involving X amount of drug Y. NOTE(S): A defined activity is represented here as a subtype of Activity, but could also be thought of as an activity at a particular stage in the business process in which the activities occur, i.e., in the "defined" stage rather than the "planned" stage, the "scheduled" stage or the "performed" stage. (NCI Thesaurus/BRIDG)
