Concept explainer
Organisations and sites
Explains how an organisation and its sites are modelled, and how this structure frames every other part of the platform.
An organisation is the legal entity that runs the hospital, and a site is a physical place it operates. Nexus Manager holds this structure, and the shape of an organisation and its sites frames every other part of the platform.
Where this sits
The hospital model is the working digital model of the hospital that every tool reads and writes through. Organisations and sites are its outermost frame. Read the wider idea at the hospital ontology.
The shape at the top
The hospital model opens with two levels. An organisation sits above one or more sites. Operational records live inside a site, while the patient record sits outside the organisation and follows the patient across every site that runs Pensieve.
Organisation
An organisation is the legal entity that operates the hospital, such as a trust or a company that runs one or more hospitals. It is a grouping label for naming and reporting, and it is the custodian and Data Fiduciary for the care it delivers, not the owner of the record. The patient record belongs to the patient and has no owning site, so a patient carries one history across every site that runs Pensieve, not only across the sites of one organisation.
Site
A site is a physical location the organisation runs, such as a main hospital building or a satellite clinic. The site is the unit of tenancy, so operational data, including visits, rosters, catalogues and charges, is authored and held at the site where the work happens.
What belongs where
The patient record belongs to the patient and sits outside this structure. Everything operational belongs to a site. The split decides where a record lives and who reaches it.
| What | Belongs to | Why it sits there |
|---|---|---|
| The patient record | The patient | It sits outside the tenancy structure, so care at any site that runs Pensieve draws on the same history. |
| Visits and encounters | A site | A contact happens at one physical place. |
| Staff roles and rosters | A site | A person works at a defined site. |
| Charges and invoices | A site | Billing settles where the care was given. |
| Reference catalogues | A site | A site authors its own orderable catalogue and charge item definitions, and the organisation scopes none of it. |
Each site holds its own boundary
One deployment serves an organisation and all of its sites. Each site's working data stays within its own boundary, and access reaches across sites only under defined conditions, decided by Cirith Manager. Read how a permission is settled at access control.
One record across sites
The patient record belongs to the patient, so a patient treated at several sites keeps one continuous history. The organisation holds no ownership of it.
A clinician at a satellite clinic reads the same diagnoses and results recorded at the main hospital.
This split keeps day-to-day work scoped to a site while the patient's single record follows them across every site that runs Pensieve. A hospital group is a grouping label, not the record's boundary. See how the record stays consistent across sites.
Reference data per site
Catalogues are authored per site. Each site holds its own orderable catalogue and charge item definitions, and the organisation does not manage them centrally for every site.
An item therefore means what its site defines it to mean, and a site draws on its own list rather than a central one. Read about the charge master.
Common questions
Can one organisation run several hospitals?
Yes. An organisation holds one or more sites, and each hospital building or clinic is a site under it.
Where does a patient's history live?
With the patient. The record has no owning hospital and sits outside the tenancy structure, so a patient seen at any site that runs Pensieve draws on the same record.
What stays scoped to a single site?
Visits, rosters, charges and most day-to-day records stay with the site where the work happens.
