The electronic health records meaningful use program has significantly increased adoption of computerized physician order entry systems, with Cerner Corp. and Epic Systems Corp. leading the way, according to a new market report from vendor research firm KLAS Enterprises.

Before MU, an average of 87 hospitals a year went live with CPOE but that average is now 233, according to KLAS. Cerner has more hospitals live on CPOE than any of the 10 other vendors in the study. Both Cerner and Epic have doubled their live CPOE sites since 2009 and both have an average of more than 80% of orders being entered via CPOE at their client sites.

McKesson is making progress with Horizon and Paragon CPOE installations but seeing adoption rates of entering orders at much lower levels than the two vendor leaders. Meditech and Siemens also are seeing implementation gains. Vendors losing momentum, according to KLAS, include Allscripts (Eclipsys), GE Healthcare and QuadraMed.

Among community hospital vendors, Computer Programs and Systems Inc. is the leader with 67 installed sites while others "are struggling to roll out the functionality," according to the firm.

For the report, "CPOE 2011: The ARRA Effect," KLAS collected data from virtually every U.S. hospital known to have gone live with CPOE in 2009-2010. The report is available for purchase at
