Electronic prescribing certainly holds a lot of promise. However, it has yet to emerge as a viable, cost-effective technology for most physicians. Still, many people believe that electronic prescribing has the potential to improve patient safety by reducing prescribing errors. A new program, BluefishRx, offers a fairly inexpensive solution ($79 for the software, plus $20/mo. if you use their wireless fax network) for the Palm OS platform, as well as a free, albeit very limited, demo version that lets you try before you buy.
