Delete randomization alert

Randomization is a process to help you avoid potential bias in the selection and allocation of subjects arising from the predictability of treatment assignments. From a statistical perspective, randomization provides unbiased estimates of error variance and independence of errors. A randomization alert is a customizable notification mechanism that generates an email to inform relevant parties when a normal or forced subject randomization succeeds or fails.

The purpose of a randomization alert is to promptly notify the responsible IWRS users about the subject randomization. However, it may occur that any of the configured randomization alerts need to be deleted due to updates in the subject randomization process or other evolving study requirements.

To delete the randomization alert

  1. In the IWRS application header, select the ALERT tab.

  2. On the page that opens, from the left pane, select the subtab corresponding to the alert category of your interest.
