According to the Brookings Inst., there are now, believe it or not, over 40,000 mobile apps aimed at health professionals and their patients.
These range in functionality from reminders, remote surveillance, treatment and medication monitoring, decision support to "telemedicine."
In the US, the FDA (food and drugs adminisration) has yet to quality-test and certify apps for efficacy.
The Washington Post reports that many apps are "based upon flimsy science at best".
Doctors in the US are reportedly early-adopters of apps for both mobile and tablet PC, and the move towards mHealth is inexorable.
For example, the Brookings Inst. estimates that savings of 25% in the care of elderly are feasible through mHealth.
