Good access control answers two questions, not one: who can do something, and when. Most systems only handle the first.
Granular, per-hospital roles
Permissions in OlivHealth are fine-grained and scoped to a hospital. A front-desk role, a billing role and a hospital administrator role each see and do exactly what they should, no more. Roles belong to a specific hospital, so a person who works at two hospitals has two clearly separate accounts rather than one blurred set of powers.
Operating-hour access windows
Staff logins can be restricted to working hours. Outside a staff member’s configured window, access is refused, a simple, powerful control for reducing after-hours risk to patient data. Owners and administrators are exempt, so oversight never gets locked out.
Changes propagate quickly
Because the app re-checks permissions and access continuously, a role or schedule change takes effect without waiting for anyone to log out and back in. Access control that only updates “eventually” isn’t really control.
