What is the difference between the types of reports?

The article 'The structure of Castor'  describes two different report types: measurements and unscheduled events. Within measurements, there is only the type 'repeated measures'. Unscheduled events can be of the type: 'adverse event', 'medication', 'unscheduled phase', 'event', and 'other'.

In this article the differences between the repeated measures and other report types are described.

Repeated measure

A repeated measure is as a measure, that can have more than one single value for each record in the study, e.g. the heart rate (BPM) that needs to be measured several times throughout a study. We expect to have an undetermined number of measurements, so adding only one regular number field to a form would not be sufficient. In that case you can use a repeated measure.

Repeated measures have an additional feature that differentiates them from the other reports. They can be added to any step as a field and the repeated results will be visualized in the form:

A repeated measure can only consist of one step.

Unscheduled report types

The other report types fall under one category, the unscheduled reports. For these report types, it is possible to add an 'Add report' button to your study forms. Other than the naming convention, there are no functional differences between these report types.

Adverse Event

Register here any unexpected and undesirable experience occurring in relation to the use of medication. An AE will be considered SAE (Serious Adverse Event) if it results in:  hospitalization, congenital abnormality, permanent disability or damage, life-threatening conditions, or death. 

Medication

This report is used to keep track of other concomitant medications, that is not directly related to the study itself. 

Unscheduled phase

The data gathered in an unscheduled phase report depends greatly on your study. Sometimes information is missing from a previous visit and the patient is interviewed again. It can also be that the patient requests a new visit to confirm the treatment is going as expected, if there are potential adverse symptoms. 

Event

The event report is a broad concept to register any event that could be relevant for the outcome of the study. An example would be a patient being unavailable for some time during the study for personal reasons. It may be that a phase needs to be re-scheduled and an explanation provided via an event report.

Other

The report 'other' contains information not applicable to the other kinds of reports.  A very specific use of this kind of report is detailed in the article Notifications for Serious Adverse Events.
