Segregation is the whole game when you hold records for many hospitals at once. Medical IT Company gives each client its own credentials, access rules, and encrypted storage boundaries, so records pulled from one Epic environment never mix with another client’s fulfillment. Access is tied to minimum-necessary roles and logged down to the individual user and request. If an OCR inquiry or client audit arrives, we can show exactly who touched what and when. That structure keeps every BAA you signed defensible.
