Epic and Cerner have moved into first and second place, respectively, for EMR market share in the more than 200 bed market, according to findings from a new KLAS study Clinical Market Share 2012: Meaningful Use Momentum Continues.

The study looks at the clinical vendor market share across 1,470 U.S. hospitals and 151 Canadian hospitals.

KLAS reports that Allscripts, McKesson, MEDITECH, and Siemens signed new customers but in the end lost market shares in larger hospitals as organizations steer toward higher levels of integration and clinical functionality.

“Many providers who might normally be patient with their vendors feel they can’t afford to wait,” said Colin Buckley, author of the report. “They want an integrated platform with stable meaningful use functionality that their physicians won’t fight them over. Additionally, meaningful use deadlines are forcing some providers back to the market sooner than expected.”

The report also compares vendors in three scenarios of special interest to providers considering a new EMR: satisfaction for clinical users, rate of meaningful use attestations and quality of implementations. Vendors’ performance in these three areas correlates with market share success.
