Abstract

The explosive growth of handheld personal digital assistants (PDAs) in health care has been nothing short of amazing. What applications - business and clinical - do these devices have in medicine, and what is their potential? PDAs are simple and intuitive; their applications require minimal interaction time, so they have minimal impact on work flow; the investment is small; and the lightweight form is relatively nonintrusive during a patient encounter. The devices are being used to capture charges for medical services at the point of care. Encounter capture, online prescription writing and other applications will soon come on the scene. This article discusses current and possible future uses for PDAs in health care, interfaces with other technologies and security concerns.
