Healthcare cannot be reduced to customers, jobs and invoices. Patient, practitioner, episode, encounter, order, specimen and result each carry distinct identity and lifecycle rules. Clinical documentation may be amended but should not be overwritten, and access can depend on relationship, purpose, sensitivity and jurisdiction.
We model administrative and clinical boundaries deliberately. Workflow screens minimise duplicate entry while durable provenance records authorship, source and amendment history. Regulatory and professional obligations vary by location and organisation; the client’s counsel, privacy officers and auditors define the requirements, and the system is built to implement what they specify.
