Top 10 physician groups using Oracle Cerner's Ambulatory EHR

Ambulatory care or outpatient care is one of the fastest-growing segments in healthcare. As physicians deliver a higher volume of care in ambulatory settings, ambulatory electronic health records (EHRs) are becoming a primary hub for patient data. While inpatient EHRs are more suited for hospitals, ambulatory EHRs are designed to support outpatient care facilities and smaller practices.

According to Definitive Healthcare data, Oracle Cerner is the second most popular ambulatory EHR vendor in the U.S. with a market share of 23.21%. Cerner Ambulatory EHR aims to help healthcare providers enhance clinical and operational efficiencies while improving patient care and experiences. The most popular ambulatory EHR vendor is Epic Systems, with a market share of 41.1%. You can learn more about the top physician groups using Epic's EHR here.
