The BRCA clinical decision support tool described in this research report has not undergone a large-scale clinical evaluation. Its ability to protect patient data from Web-based security breach needs to be evaluated. Hence, this first version of the tool is not available for download since it is not considered ready for clinical use. It is available to researchers, upon request, for further evaluation and modification. Individuals who wish to obtain a CD of the tool for evaluation should contact AHRQ program staff using the following e-mail: ProjectManagerCE@ahrq.hhs.gov.
