The software in this space is terrible. The system is designed for admins not practitioners. For example blood pressure entry is odd with two boxes. Note capture is slow due to needing it be typed rather than written. Sharing out of the core system is onerous.

FHIR would be a good idea, but in practice its hard to correlate a patient across the systems. Few hospitals and doctors setup a push notification for when they change a patient's record.

Essentially all of the software needs to be redone with a focus on a centralized record tracking system. The rewrite needs practitioners (all of them, not just Docs, but the lowly CNA too) to drive the requirements. Admins should be included, but not the target of day to day UI.
