The global EHR market will reach $22.3 billion by the end of 2015, with the North American market accounting for $10.1 million or 47 percent.

Accenture's forecast also sees the U.S. market hitting $9.3 billion with a 7.1 percent annual growth rate and remaining the largest EHR market globally.

Consolidation and Meaningful Use are the biggest market drivers in the U.S., according to the consulting firm. Brazil's EHR market is the next biggest at $400 million with an expected 9.7 percent annual growth. Accenture estimates the global EHR market will grow at a rate of 5.5 percent annually through the end of next year.

“Our research is clear that EHR growth may have slowed, but the market has nowhere to go but up,” said Kaveh Safavi, Accenture Health's global managing director, in a statement. “To be effective, EHR platforms must leverage newer technologies, such as analytics and mobility, to adapt to the changing needs of patient populations and better connect physicians and patients. As health systems gain more experience in meeting these goals, market growth for EHR will follow.”
