Open Source EMR
An electronic medical record is the rare system where the data must outlive every vendor that touches it - a patient's history has to be readable in thirty years and portable to whatever clinic comes next, which is exactly what proprietary schemas and locked exports quietly prevent. The open source EMR systems here build on HL7 and FHIR with the database under your roof, so the longitudinal record and its audit trail stay in standards another system can actually consume, not trapped behind a license you keep renewing to read your own patients.
