Epocrates Bugs + Drugs App Goes Viral With 100,000 Downloads in First Month

New App Improves Clinician Awareness of Local "Superbugs" and Informs Rx

WATERTOWN, Mass., Oct. 31, 2013 (GLOBE NEWSWIRE) -- athenahealth, Inc.
(Nasdaq:ATHN) and Epocrates today announced that the new joint medical app,
Epocrates Bugs + Drugs, has hit the 100,000 download mark since its release
earlier this month. Epocrates Bugs + Drugs, an antimicrobial susceptibility
reference sourced from athenahealth's big data that helps clinicians identify
local superbugs, shot to the #1 free medical app in Apple's App Store in its
first week. To date, it has earned 4+ stars, with users calling it "sleek and
informative," "super fast" and a "pretty awesome concept."

The majority of targeted bacterial searches in the app are in higher-risk
metropolitan areas, such as New York, Los Angeles, and Chicago. Furthermore,
the localized sensitivity patterns for organisms including E. coli and Staph
aureus, commonly found in urine and skin infections, are among the most viewed
by the app's users.

Dr. Gerry Tolbert, a family physician, was initially drawn to the beautiful
design of the Epocrates Bugs + Drugs app. The app's value was quickly evident
during patient consultations, and it has since earned a spot in his practice
toolkit. "It is sometimes challenging to judge what the resistance is for a
presenting bacteria. By displaying resistance patterns in my area, Epocrates
Bugs + Drugs helps ensure that I prescribe only one course of antibiotic and
avoid medications that have shown to be resistant," said Dr. Tolbert.
"Epocrates helps me create a successful treatment plan, which provides higher
levels of patient compliance and satisfaction."

"We add more than 6,000 lab isolate data points every day to the network to
generate fresh results. This is a great example of how aggregated EHR data can
be utilized, and clinicians have clearly responded to it. The app has now been
accessed more than 300,000 times since launch, with an average of
approximately 4,000 uses a day," said Abbe Don, vice president of user
experience at Epocrates, an athenahealth company.

Epocrates Bugs + Drugs was created to provide the nation's clinicians with
geo-located bacterial resistance data sourced from athenahealth's cloud-based
clinical database of 15 million patient records. Results can be viewed for
bacteria by specimen types and is paired with Epocrates' trusted drug content
to inform prescribing decisions.

Epocrates Bugs + Drugs is now available at no cost for iOS 7 devices in the
Apple App Store: http://bit.ly/18uyL3n.
