We were recently exploring the new updated Certified HealthIT Product List (CHPL) site (https://chpl.healthit.gov/#/search ) was were shocked that as of today (Jan 11, 2017) there are only 3 Health IT vendors that have products that have been Safety-enhanced Design certified for the ONC 2015 Edition.
We're glad that for most EHRs the usability test performed as part of their certification is posted on the website of the certifying body (eg, Drummond, Infoguard, etc)
