Health care reform's emphasis on population health management is moving providers toward electronic health records systems that can document care in both inpatient and outpatient settings. That may be a key reason why the (formerly) outpatient EHR provider Athenahealth announced today at the J.P. Morgan Healthcare Conference that it has agreed to buy RazorInsights, an electronic health record and financial platform for rural, critical access, and community hospitals. Athenahealth CEO Jonathan Bush said his company plans to leverage RazorInsights' inpatient expertise and technology to extend its presence into the 50-bed-and-under hospitals, which accounts for about one-third of the total U.S. hospital market.
