Setting up randomization
Randomization in an InForm trial enables the trial to randomly assign drug kits or devices to patients.
On the development side, the application engineer:
- Incorporates the randomization feature into a trial by using rules attached to items on a form.
- Implements the feature as a button on a randomization form using the appropriate UUIDs included on the form, section, and item of the randomization form or the form responsible for issuing randomized IDs.
- Creates a randomization database.
Note: A sample Microsoft Access database is included in the sample trial. To use an Oracle randomization database, create an Oracle schema with a table structure that is identical to the sample Microsoft Access database.
On the production side, you must configure the trial to use the randomization database.
- Use this pfadmin command:
pfadmin config trial <trialname> /rnd <pathfilename.dbextension>
where
- <trialname> is the name of the trial for which you are setting up the Randomization feature.
- /rnd is an option that does two things: creates a DSN for the randomization database; configures the trial to use the DSN.
Note: You can also use /RndDSN to configure a trial to use an existing DSN.
- <pathfilename.dbextension> is the filename of the datafile containing the Randomization database.
- Restart the InForm service to complete randomization configuration.
