Telehealth: Seeing, and Treating, Patients at a Distance
Rhonda Johnston, a nurse practitioner, has a simple requirement when it comes to the technology that allows her to serve patients scattered across southern Colorado: “Our goal is to make sure the telehealth patient encounter is no different than a traditional encounter.” If that can be accomplished, she said, “telehealth can be a very useful tool.” Also known as telemedicine, the practice of interacting with patients at a distance is being implemented to serve ...

State of the economy 2010
There’s a prodigious pachyderm in the parlor, but nobody is able to agree on just how big it is or whether it is about to rampage through the house. The beast, of course, is the Patient Protection and Affordable Care Act (The baby hanging onto...
