Introduction
Study Flow
The study flow in the Clinical Data module shows the pathway of activities a patient follows during a trial and dynamically triggers the corresponding clinical data to be completed. The flow is always initiated by the registration of the patient followed by the activities as defined by the protocol. This section consists of a summary table listing the activities, followed by a graphic study flow highlighting the patient specific pathway.
Activity
An activity is a step in a subject’s possible path from accrual to end of study. The initiation of an activity (automatically or by the user) causes the correct eCRFs to be triggered in the data section of the Clinical Data module.
There are several types of activities, which type dependent behave differently in the flow:
- Each flow starts with a registration, which might require eCRFs to be completed or not.
- A randomization will allocate a protocol arm by minimization, an eligibility test on the data reported can be part of the design.
- An arm can be allocated based on information provided on the eCRFs, either automatically or requiring manual confirmation, by means of a decision node.
- A milestone allows manual selection of the next activity, not requiring data completion.
- Each flow will end with an end of study flow activity, which is considered as the official stop of the subject in the study flow.
Navigation to Study Flow
The study flow can be accessed by selecting a subject from the subject overview or via the study flow button displayed per subject.
The data section in the clinical data module displays both a general navigation button to the study flow as a specific button to the corresponding activity, depending on the event displayed on the screen.
Activity Overview
All reported activities are listed with the the corresponding start and end date as well as the user closing the activity, the signature status and the link to the corresponding clinical data (to be completed).
Selecting an activity in the overview causes the activity details to be expanded. The activity details give access to the activity specific audit trail and displays relevant data linked to the specific activity. For a randomization or an eligibility the activity details give access to the general and detailed test results generated by such test activities.
If the activity is already closed a button is displayed which allows you to navigate to the 'next activity'. This option automatically collapses the current activity and expands the next activity in the overview table.
If the activity is still in progress (i.e. not closed) the activity details can contain messages requesting data to be completed or tests to be executed before the activity can be closed.
Graphic Study Flow
The graphic study flow indicates the theoretical possible pathways corresponding to the protocol and highlights the subject specific pathway. The difference in colors of the activities indicate the status of the activity.
