Personal digital assistants: a review of their application in graduate medical education.

Personal digital assistants (PDAs) have become widely used in medicine and may be especially useful in achieving the goals of graduate medical education. The complex challenges that residents and their program directors in graduate medical education programs confront may be met more readily with the use of these devices. The PDA's ability to serve as an informational database, an organizer of patient-specific information, a tracking tool that can be used by program directors to enhance curriculum design, and a tool for conducting education research are some of the ways that these devices might favorably affect residency training in graduate medical education programs.
