This goes back to the use of the Apple Newton MessagePad in
healthcare, one of the markets segments where the Newton did very well.
The article talks a lot about the "patient" side of using a PDA to manage personal well-being but fails to touch on the impact on the provider side of the equation.
As handheld computers get more powerful and wireless networks become ubiquitous in hospitals and doctor's offices, the PDA is truly becoming an indispensible tool for physicians and other healthcare workers. They can carry the entire
Physician's Desk Reference and use programs like
ePocrates or
PatientKeeper to help in the diagnosis of illnesses, then track and manage the patient's history and billing in a HIPAA compliant application. PDAs can also be used by healthcare workers or the patient to fill out questionnaires and other forms.
They are also an inexpensive, portable, viable laptop replacement for clinicians working with limited resources and in underdeveloped areas.
