Dacima’s Randomization module provides a powerful and flexible state-of-the-art web patient randomization software application (IWRS) implemented and fully integrated into our eClinical Suite for clinical trials, which allows you to configure your patient randomization process and set up your enrollments/eligibility form(s). 


Working with our user-friendly Graphical User Interface (GUI) you can easily configure your randomization process and setup your enrollment/eligibility form(s) without the need for any programming expertise. Easily design your enrollment form, create validation checks and eligibility rules, configure your patient ID format and more by simply activating the properties you need. You can either setup a single enrollment form or, if your study requires steps or stages for patient enrollment, you can configure a multiple enrollment form.


Easily randomize patients with only a few clicks by simply completing web enrollment/eligibility form(s). The software checks the patient’s eligibility criteria and notifies of the treatment allocation.
Role-based user access allows you to manage different levels of access for trial coordinators, investigators, nurses, monitors and biostatisticians. Coordinating centre can manage patient randomization or for multi-centre trials, patient randomization can be delegated to participating centres. Automatic email notifications and a powerful subject management screen allows you to track the randomization process and manage your patients.
