About
Oracle Health is the healthcare technology business unit of Oracle Corporation (NYSE: ORCL) — providing electronic health records (EHR), clinical workflow management, health information exchange, revenue cycle management, and population health analytics to hospitals, health systems, physician practices, ambulatory clinics, and government health agencies globally — operating as the rebranded Cerner Corporation following Oracle's $28.3 billion acquisition of Cerner in June 2022, the largest acquisition in Oracle's history. Oracle Health's EHR platform (the Cerner Millennium clinical information system) powers clinical documentation, physician order entry, nursing workflows, medication administration, and patient care coordination for approximately 30% of US hospitals — making Oracle Health the second-largest EHR vendor in the US hospital market after Epic Systems. A major integration program is underway to migrate Cerner's clinical applications to Oracle Cloud Infrastructure (OCI), enabling Oracle Health to leverage Oracle's cloud scale, Oracle's AI capabilities (generative AI for clinical documentation, ambient listening for physician notes), and Oracle's database performance advantages for health record analytics. Oracle Corporation named Clay Magouyrk and Mike Sicilia as co-CEOs in 2025 (replacing Safra Catz), positioning Oracle Health's clinical platform to benefit from the next-generation Oracle leadership team's emphasis on cloud and AI transformation.

About
eClinicalWorks is one of the largest electronic health record (EHR) and practice management software providers in the United States, serving approximately 150,000 providers across 850,000 care sites with ambulatory EHR, revenue cycle management, patient engagement, and population health tools. Founded in 1999 by Girish Navani and headquartered in Westborough, Massachusetts, eClinicalWorks is privately held and is notable for being a bootstrapped company that has grown to significant scale without venture capital funding, generating substantial annual revenue from its large installed physician base.\n\neClinicalWorks' platform covers the ambulatory (outpatient) clinical workflow: clinical documentation with specialty-specific templates, order entry for labs and imaging, e-prescribing, chronic disease management registries, telehealth (healow TeleVisits), and patient portal. The revenue cycle management capabilities handle insurance claims submission, denial management, and patient billing. Population health tools enable practices and health systems to identify at-risk patient populations and coordinate care across attributed patients.\n\nIn 2025, eClinicalWorks competes with Epic (the dominant health system EHR), athenahealth (cloud-native ambulatory EHR), Oracle Health (Cerner), and Modernizing Medicine for physician practice EHR market share. The company has faced regulatory challenges — in 2017, eClinicalWorks paid $155 million to settle Department of Justice charges related to EHR certification fraud. Despite this, the company retained most of its customer base due to high switching costs inherent in EHR changes. The 2025 strategy focuses on its AI assistant Sunoh.ai (ambient clinical documentation that automatically generates SOAP notes from recorded patient visits), expanding telehealth capabilities, and growing the healow patient engagement platform.
