An activity plan is a schedule of events for a given cohort. Activity Plans do not appear in CDSIC. In ODM, there is the notion of a FormRef. However, this design doesn't fit well with ph1 trials where forms are commonly repeated for a given study event (ie many PKs in a given day). As such, FormRef is implicitly available by way Scheduled Activities that are a part of a Segment / Activity Plan.
| Table | From CDISC? | Notes | |
|---|---|---|---|
| 1 | Study | Yes | This element collects static structural information about an individual study. A study is related to a given clinical trial protocol. |
| 2 | Activity Plan | No | A schedule of events for a given cohort. Plans can be assigned to multiple cohorts. A timed plan must have a reference time in order to properly provide UI feedback as segments and scheduled activities are set. Untimed Activity Plan:
Activity Plan fills the role of the FormRef in the ODM. |
| 3 | Segment | Partially | Holds a group of scheduled activities in an activity plan. The segment's offset seconds is essentially the time of the reference event, all scheduled activities are relative to this. Modeled somewhat of off CDISC SDM: "Segments are often seen as the basic building blocks of study design. A segment usually specifies a combination of planned observations and interventions, which may or may not involve treatment, during a period of time." |
| 4 | Scheduled Activity | No | Wraps a form, but adds metadata including timing. |
| 5 | Form | Yes | A form is basically a container for item groups. |
| 6 | Study Event | Yes | A study event represents a given 'visit'. In phase 1 trials this will commonly simply refer to a 'day'. When scheduling forms for a given schedule, the builder must associate the study event. Note: there are common study events that are typically reserved for special events: unscheduled, common (AE, CM), etc |
