For small physician practices: Epocrates EHR.
Why You Should Watch: Epocrates has long been the unquestioned leader in (mostly mobile) electronic drug reference tools, with a user base that now stands above 1.4 million healthcare professionals worldwide, including 340,000 physicians in the U.S. alone. So the healthcare world was excited when the San Mateo, Calif., company announced at HIMSS10 that it was developing an EHR for both the Web and iPhone, aimed at small physician practices.
The EHR was supposed to come out in the fourth quarter of 2010, but a "core" primary care version for practices with 10 or fewer doctors didn't hit the market until July 2011. The company hasn't given much detail on how well this new product is doing, but if the EHR is anywhere near as intuitive as the free Epocrates Essentials reference guide, it could prove highly popular.
Also worth watching from this vendor: Epocrates recently added Eric Tseng, head of mobile products at Facebook, to its board of directors. Could social media be part of the company's strategy?
