Epic is the largest provider of EHR systems in the United States, accounting for more than 30 percent of all inpatient and ambulatory systems. As hospitals and care facilities continue to utilize electronic data sharing, and hospitals implement multiple EHR systems across inpatient and ambulatory departments, there could be a greater incentive for smaller companies to market less-comprehensive niche products to fill gaps in service.
Currently, Definitive Healthcare tracks more than 14,097 inpatient and ambulatory EHR implementations. Epic accounts for approximately 35 percent of ambulatory and and 30.6 percent of inpatient systems in place, the most of any single provider. In second place is Cerner, accounting for 26.2 percent of ambulatory and 25.1 percent inpatient EHR systems. Meditech has the third largest percentage of ambulatory and inpatient EHR systems in place with 11.1 percent ambulatory and 14.7 percent inpatient implementations.
While some hospitals choose to implement a single system, others use a patchwork of different systems depending on departmental needs. EHR interoperability challenges can make this difficult for some facilities. Abilene Regional Medical Center (TX) uses the Medhost patient portal and inpatient EHR system, and an ambulatory EHR system from AthenaHealth, according to Definitive Healthcare data. Carolina's Medical Center uses Cerner as their Healthcare Information System and inpatient EHR system, but uses Epic for their ambulatory EHR and patient portal according to Definitive Healthcare.

However, though hospital and care center EHR adoption continues to rise, this does not necessarily ease the flow of patient and provider data. A study published in Health Affairs this September found that physicians spend more time on “desktop medicine,” logging data and answering patient queries online, than in face-to-face patient interactions. This leads industry experts to believe that the emphasis on electronic data logging is taking up too much time in a physician’s day, reducing the time spent with patients diagnosing medical issues.
It is interesting to note that every one of the largest hospitals using this system is part of a larger health system. The largest hospital currently using Epic, and is not part of a health system, is Tampa General Hospital with 920 beds.
