Electronic Health Records (EHRs) are a critical but expensive part of any hospital’s technology infrastructure. The following lists highlight the top ten vendors for Inpatient EHR Systems and Ambulatory EHR Systems. For both inpatient and ambulatory, Epic Systems maintained the highest market share — accounting for 39 and 41 percent of deployments, respectively. At 22 and 23 percent implementation, Cerner holds the second-highest vendor market share for both inpatient and ambulatory [EHR] systems."

In both EHR system types, the vast majority of facilities utilized Epic, Cerner, MEDITECH, or Allscripts. Median total revenue at hospitals saw a large drop off after the top four vendors. For Inpatient EHR, hospitals using one of the top four vendors had a combined average total revenue 149 percent higher than the average total revenue of hospitals using alternative vendors. The revenue disparity lessens when examining ambulatory EHR system deployments. Hospitals using one of the top four vendors had a combined average total revenue 85% higher than the average total revenue of hospitals using alternative vendors. eClinicalWorks serves as an exception in the ambulatory space with the fourth highest average total revenue for user hospitals.

Proprietary systems account for only about 2 percent of all inpatient and ambulatory EHR systems across U.S. hospitals. This is because the vast majority of hospitals using a proprietary system are part of national, for-profit corporations. Their higher [operating] margins and large geographic footprint make building and maintaining an in-house system a more practical solution for them than other, more widely-utilized vendor technologies.

For Ambulatory systems, Evident, which focuses its products on rural, community, and critical-access hospitals, was installed at hospitals with the lowest median patient revenue, median discharges, and lowest rate of affiliation with IDNs.
