California, serving more than 200,000 members in the San Francisco Bay

technology to simplify work processes, improve billing functions,
create more efficiencies and reduce the difficulty of running a
physician practice,” said Gloria Austin, Brown & Toland’s Chief
Executive Officer. “The solutions provided by IDX and Allscripts
Healthcare perfectly align with our goals to provide practice
management services to our physicians and to reduce healthcare costs
for our patients.”

The IDX and AHS implementation includes coordinated project
development and service to deliver a complete, integrated solution for
practice management and clinical automation.

“This agreement with Brown & Toland re-emphasizes the value of our
strategic relationship with IDX,” said Glenn Tullman, Chief Executive
Officer of Allscripts Healthcare Solutions. “The combined strength of
the industry’s leading practice management system provider and the
industry’s leading ambulatory EMR provider offers an unmatched
solution for our healthcare clients.”

Brown & Toland physicians include approximately 315 primary care
physicians and 1,200 specialists, who are board certified in 43
different specialties. The physicians practice at some of the most
prestigious medical facilities in the nation, including UCSF Medical
Center, UCSF/Mount Zion Medical Center, California Pacific Medical
Center, and St. Mary’s Hospital.
