Randomization software

It is important that the randomization software is simple and can be used speedily. A good randomization program should have the following features.

♦ Eligibility criteria automatically checked.

♦ Stratification and minimization by many variables possible.

♦ Interactive 24-hour secure randomization available over the Internet. (Other modes of randomization must be available for when access to the Internet is not available; randomization by telephone maybe easier for many clinical centres.)

♦ Patient entry directly confirmed by fax, e-mail or post.

♦ Summary details of patients on trials available.

♦ Downloading of randomization information onto a variety of databases, including data-management programs, statistical packages and ASCII files, possible.

♦ Portable across many operating systems.
