Top 20 physician groups using Epic Systems EHR

Similar to hospitals and other healthcare facilities, physician groups use electronic health records (EHRs) to track a patient through their care journey. However, most physician groups primarily use ambulatory EHRs, which are specifically designed to meet the needs of small physician practices and outpatient centers.

Many physician groups use Epic Systems Corporation, which is one of the largest EHR vendors in the country. Epic has the highest percentage of market share amongst its competitors, at about 37%.

Below, we used the Definitive Healthcare PhysicianGroupView product to rank the largest physician groups in the country that use Epic as their EHR provider.

What is the largest physician group that uses Epic ambulatory EHR?

Southern County Permanente Medical Group is the largest physician group we track that uses Epic’s EHR system. Located in Downey, California, the group has more than 12,000 physicians in the group.  In second place is The Permanente Medical Group based out of Davis, California with just over 10,000 physicians.

Both Southern California Permanente Medical Group and The Permanente Medical Group are part of the same integrated delivery network (IDN), Kaiser Permanente, one of the largest IDNs in the country. Many physician groups are associated with IDNs, because that association gives them access to more resources while IDNs can expand their services to serve patients in various communities.   In addition, many IDNs select ambulatory EHR that they require all affiliated physician groups to use.

Rounding out the top three is Select Physical Therapy in King of Prussia, Pennsylvania. Select Physical Therapy is one of the largest physical therapy networks in the U.S. with over 8,000 physicians across a wide range of specialties.

What is the difference between inpatient and ambulatory EHR?

While inpatient and ambulatory EHRs may seem similar at first glance, they are actually designed for different purposes in a patient's healthcare journey. In most cases, ambulatory EHRs tend to be simpler than their inpatient counterparts. Ambulatory EHRs manage a single practice and its patients, rather than a complex web of hospital departments serving thousands of patients.

Inpatient EHRs are designed for patients that need to stay overnight for their care and have needs across multiple departments for their care. Because of these requirements, inpatient EHRs are often used more by hospitals and other long-term care facilities.
