After a randomization has been setup on a study, the allocation table can be viewed. This is found under the Subject menu:




This following figure shows the View Randomization Allocations interface that allows the user to decode the randomization file.  This page will also display all planned and assigned randomization allocations. This page can be displayed for each defined randomization in the system.

 



The Randomization Allocation data table on the View Randomization Allocations page, shown in the figure above, displays all planned and actual randomization allocations. The user can see the randomization file that was uploaded by viewing the first four columns of the Randomization Allocation data table (Please Note: This particular randomization scheme is NOT returning a Subject Profile ID). The last three columns in the Randomization Allocation data table contain the actual allocations including the site, subject and date of allocation.


When a user saves a form that was defined for a particular randomization, the system will find the next available slot based on the site and stratification(s). The system then claims that slot by assigning the user’s site, subject and date of allocation to that slot. The system also associates this randomization allocation to the subject's visit. This information can be used to enforce randomization arms using Conditional Actions.


The View Randomization Allocations page gives the user the ability to decode the randomization allocations. For each allocation that was imported for a given randomization, the user can enter text to be displayed whenever this allocation is shown in Clinical Studio. To decode a randomization, the user simply enters in the text for each allocation and presses the "Save" button below the last allocation text box.  The decoded text will show in the Allocation column in the main data table.


The View Randomization Allocations page allows the user to view only randomizations that have been allocated. If a user has a large randomization table, the user can click the View Only Randomized Subjects link above the Randomization Allocation data table to view just those subjects that have been allocated. The user can then toggle back to view all randomizations by clicking the View All Subjects link.


At any time, by selecting the Export to Excel link located above the Randomization Allocations data table, the user can export the entire randomization table to Excel. This gives the user a permanent archive of exactly how the randomizations were allocated for the duration of the study.
