Assigning Selected Treatment Assignments to a Site

From the Design menu, select Patient Positions, choose Study Site Relations, click the Sites button, and click the Treatment Assignments button.

You can assign selected treatment assignments from all available treatment assignments for this study from this menu path. Use the Treatment Ranges utility, below, to assign sequences of treatment assignments that are coded consecutively, or the Randomizations button to narrow the selection of treatment assignments to a particular randomization.

To assign selected treatment assignments:

1. Select a randomization to assign randomized treatment assignments.
2. Click the Treatment Assignments button. You have reached this stage by selecting Patient Positions from the Design menu, then selecting Study Site Relations, and clicking the Sites button. You can also reach this display by selecting Patient Positions from the Design menu, then choosing Study Site Relations, clicking the Sites button, and then the Randomizations button; this narrows the selection to treatment assignments from a particular randomization. The remaining instructions are the same for both menu paths.
3. Select the Assign? box for each treatment assignment. The system populates the Site field with the current site selection.
4. Save.

Linking Treatment Assignments

Typically, you link patient positions to study sites, and their treatment assignments with them. You must link treatment assignments to a study site only when they do not match patient positions.

To assign or remove individual treatment assignments from a study site:

1. From the Design menu, select Patient Positions, then choose Study Site Relations.

2. Select the live clinical study version of interest. If your currently selected study does not have a live version, the system prompts to see if you want to view all studies. If your study has a live version, but you do not have it currently selected, the system prompts to see if you want to switch to the live version.

3. Click the Sites button. The system displays the Maintain Study Site Relationships window, listing all the study's sites.

4. Select a site. You can only select a study site while in this window; you cannot insert, update, or delete a study site here. (To assign sites to studies in the Investigator subsystem, from the Design menu, select Investigators and Sites, then choose Study Sites.)

5. Choose between viewing all available treatment assignments or those of a randomization:

   either: Click the Treatment Assignments button. The system displays all treatment assignments available for the study and site.

   or: Click the Randomizations button. The system displays the randomizations assigned to the study.

   1. Select a randomization.

   2. Click the Treatment Assignment button. The system displays all treatment assignments assigned to the selected randomization.

6. Select the Assign? box for each treatment assignment you want to link to your study site. Deselect the Assign? box for each treatment assignment you do not want linked to your study site.

7. Save.

Linking Treatment Assignments by Range

Typically, you can assign patient positions and their treatment assignments to study sites. You have to assign treatment assignments to a study site only when they do not match patients automatically. To select treatment assignments to link to the selected study site, work in the Link Treatment Assignments by Range window:

1. From the Design menu, select Patient Positions, then select Study Site Relations.
2. Click the Sites button.
3. Select the study site.
4. Click the Treatment Ranges button. The left side of the window displays the current state of the system and refreshes each time a you make a change.
5. Define the treatment range on the right side of the window.
6. Click the Assign Treatments button. The system removes the instructions as it acts on them.

Linking Treatment Assignment Ranges to a Site

From the Design menu, select Patient Positions, choose Study Site Relations, click the Sites button, and then the Treatment Ranges button.

You can assign ranges of consecutively coded treatment assignments to sites. Following the path given earlier, select study and site. The window displays the site's current treatment assignments on the left side of the window. The system assigns the individual treatment assignment codes according to the number and start code number you specify on the right side of the window.
