Start with individual accounts
Shared credentials make it difficult to understand who performed an action and usually grant more access than a person needs. Individual user accounts provide a clearer base for controlled access and audit history.
Design roles around work
A receptionist, doctor, nurse, laboratory user and billing user do not need the same application access. Roles should reflect the tasks a user is responsible for, then permissions can be assigned to those roles.
Keep hospital context enforced
Permissions alone are not enough in a multi-tenant product. Data queries also need the correct hospital context. The CareSync project uses tenant or hospital identifiers throughout operational workflows to keep records scoped.
Review access as the hospital changes
Roles should be reviewed when responsibilities, branches or departments change. A clean access model is an operational process, not a one-time setup screen.
