How to Choose the Right EHR System
Epic vs Cerner Which EHR System Is Right for Your Organization? For academic medical institutions or major health systems that need a lot of flexibility, can handle a lengthier and more resource-intensive installation, and value departmental consistency and deep integration, Epic is a fantastic option.
For midsize hospitals, community hospitals, or outpatient clinics that value quick adoption and reduced upfront costs, desire robust interoperability across many systems, and favor a cloud-first, modular EHR strategy, Cerner, also known as Oracle Health, is the best option.
