Epic's interface is optimized for outpatient workflows. Templates are intuitive, note writing is fast, and the system learns your preferences. Most FM residents trained on Epic report comfort within 2–4 weeks.
MyChart (Epic's patient portal) is industry-leading. Patients can request refills, view notes, message you, and schedule appointments seamlessly. This is a significant advantage for FM practices with high patient volume.
Prescription writing in Epic is fast, with excellent drug-drug interaction checking and e-prescription integration. Prior authorization requests are often handled directly.
Epic's mobile app is robust. You can review patients, place orders, and check results from anywhere. This is especially valuable for FM physicians managing ambulatory populations.
If you're considering VA, IHS, or other federal employment, Cerner experience is a major advantage. VA fully standardized on Cerner (VistA modernization), making Cerner expertise highly valued.
Cerner is excellent in large, complex health systems where inpatient, outpatient, and lab workflows are tightly integrated. If you work in an academic center, Cerner handles the handoffs well.
Cerner allows extensive configuration for complex workflows. If your practice has unusual requirements, Cerner can be tailored more deeply than Epic.
Cloud-based, common in smaller practices and urgent care. Fast, user-friendly, but limited integration for complex health systems. ~5% market share in FM.
Popular in small FM practices. Affordable, decent workflows, but less sophisticated than Epic/Cerner. ~10% of independent practices.
Growing in independent practices, modern interface. Less established track record in large health systems.
