Data set merges information about the Centers for Medicare and Medicaid Services, Medicare and Medicaid EHR Incentive Programs attestations with the Office of the National Coordinator for Health IT, Certified Health IT Products List. This new dataset enables systematic analysis of the distribution of certified EHR vendors and products among those providers that have attested to meaningful use within the CMS EHR Incentive Programs. The data set can be analyzed by state, provider type, provider specialty, and practice setting.
It is a large data set with 92,582 records I ran a quick analysis to find the top 10 ten vendors (both inpatient and ambulatory and EP and Hospitals) just for fun. Note the data appears to be from April 2012 and it should be updated monthly but hasn't yet.
The top ones are

|Greenway Medical Technologies, Inc.||2436|
