Feature
Centralized Patient Data
Every record in one secure place, from medical history to billing.

One record per patient, readable by every department with a right to see it. Admissions, labs, imaging, billing and discharge all write to the same file, so nobody rebuilds a history from three systems and a phone call.
Changes propagate immediately and every edit is attributed. When a clinician opens a chart they see the current state, not a copy that went stale overnight.
