The brief
A hospital that owns its data but rents the view of it
Navavej International Hospital runs its clinical, finance and nursing work on separate vendor systems, as most hospitals do. None of them can answer a question that crosses the boundary, such as which credentialed staff are on a department floor tonight against the beds occupied, without somebody exporting and re-keying.
Opsian's proposal to the hospital is an intelligence layer that sits over those systems rather than replacing them. The engagement started with an audit and a partnership kickoff at the hospital in Bangkok, walking the departments before anything was proposed.

The architecture
Read first, interpret second, replace last
The proposed layer follows CareCore, Opsian's hospital product. It reads from the systems in place without changing them and gives every patient, encounter, order and charge one definition. It answers questions with sources cited and only within a person's role, and it applies the hospital's own policies.
Nothing is switched off on day one. The path runs in phases, from observing and mirroring the existing systems to interpreting them, drafting outputs behind human approval, replacing low-risk modules and, only when the hospital decides, touching core records. Reporting and portals move first. Medication administration and intensive care systems are last.
What was built
NavCare and the accounting application
NavCare is the staffing prototype Opsian built for the hospital. It covers shift coverage across departments, call-outs matched to available staff, a fatigue and rest-rule engine with supervised override, department bed grids and rosters, clinical skills, and credential and training compliance, with reports on top. It runs in English and Thai.
Alongside it, Opsian built an accounting application for the hospital, the finance side of the same principle: one record per transaction, reachable by the systems that need it, with an audit trail that can be replayed.
The work is framed as proposal and prototype. It is the evidence that the architecture Opsian runs in hotels carries over to a hospital without being rebuilt.
Built on
Built on CareCore and the Opsian audit
The intelligence layer is the CareCore architecture applied to Navavej's systems; the prototype and the accounting application are custom software on the same data model.
- CareCorePatient identity, admissions, flow, orders and billing on a vendor-agnostic data layer, adopted in phases alongside existing systems.
- AuditingThe examination of the operation, its data and its systems that every Opsian engagement starts with.
- Software DevelopmentNavCare and the accounting application, built in house with permissions and audit logging from the first release.
Outcomes
- A proposed architecture that gives the hospital one view across clinical, finance and nursing systems without replacing any of them.
- NavCare, a working staffing, coverage and credential-compliance prototype in English and Thai.
- An accounting application built for the hospital's finance team.
- A phased path in which each step delivers value before the next begins and the hospital keeps control of the timing.
