Guidelines deserve better
than a PDF.
Distribution
Medical societies publish clinical guidelines as PDF documents. Distribution happens through email, websites, or conference proceedings. There is no version control. No structured notification system. No way to know who follows what.
Interpretation
Each hospital interprets guidelines manually. Two departments in the same specialty, ten kilometers apart, may follow the same guideline differently. Neither knows. Neither can measure it.
Institutional memory
Departmental knowledge lives in people, not systems. When someone retires, changes position, or is absent for a week - knowledge walks out the door. New staff have no structured path to competence.
DeOS - Department
Operating System
An operating system for hospital departments. It connects clinical guidelines with daily workflow: who does what, when, and why.
DeOS transforms guidelines from passive documents into active, executable models. Decision logic becomes deterministic tables. Workflows become visible processes with clear ownership. Everything is versioned, traceable, and auditable.
No patient data required. No IT department approval process. No technical expertise needed. DeOS operates alongside existing systems - ready to deploy from day one.
What DMN gives that PDF cannot.
| DMN | ||
|---|---|---|
| Executable logic | "Melanoma >1 mm should be re-excised with 2 cm margin" | IF breslow > 1.0 THEN margin = "2 cm" - testable, runnable, verifiable. |
| Automatic diff | Read 47 pages. Find the changes yourself. | git diff v1.0..v2.0 shows exactly which rules changed. |
| Impact analysis | Manual review across departments. | Run new DMN against your data: "312 patients would have had a different pathway." |
| Dependencies | Footnote: "cf. AJCC 8th edition" | Declared dependency - system warns on incompatibility. |
| Traceability | Who interpreted it? When? How? | Full version history: author, date, verification status, audit trail. |
| Distribution | Email with attached file. | Library notifies subscribers. Pull when ready. Merge on your terms. |
Build once. Use everywhere. Maintain always.
BPMN for process.
DMN for decisions.
Two open standards that weave through the entire patient pathway. BPMN defines who does what, when. DMN defines what should be done, based on evidence. Together, they form a complete, auditable chain from guideline to bedside action.
Clinicians see a simple step-by-step wizard - not these technical diagrams. These are what powers it underneath.
Watch. Diff. Review. Merge.
Guidelines are never pushed. Departments adopt updates on their own terms, with full visibility into what changed and what it means for their practice.
The DMN Library is a versioned collection of clinical guidelines transformed into executable decision models. Each entry carries declared dependencies, verification status, and a full change history. When a medical society updates a guideline, the Library provides the structured diff - departments subscribe, review, and merge on their own schedule.
A medical society updates a guideline. Your department is notified automatically. No email chains. No missed updates.
See exactly what changed. Which rules. Which values. Which thresholds moved. Side by side, old versus new.
Run an impact analysis against your department's practice. How many patients are affected? What changes operationally? Discuss with your team.
The department actively merges the update. Only then does it take effect. No silent changes. No automatic pushes. You decide.
ETHOS is not a slogan.
It is how we build.
No hidden logic.
Every decision rule can be opened, read, and understood. If you cannot see how a decision was made, it is not a decision - it is a guess.
Source to bedside.
Every clinical rule traces to its origin - author, version, publication date, verification status. No rules without provenance. If it has no source, it does not exist in our system.
Decisions are assets.
A clinical decision is not something that "just happens." It is modeled, versioned, tested, owned. Treated as a first-class operational resource - like a building or a patent.
No lock-in. Ever.
BPMN. DMN. FHIR. Only open standards. You can leave us and take everything with you. Your data, your models, your decisions. Exported, portable, yours.
Watch. Diff. Review. Merge.
Guidelines are never pushed. Departments watch for updates, see exactly what changed, review the consequences against their own practice, and merge on their own terms.
Machine assists. Always.
The human decides. AI accelerates and assists, but the base system is 100% human-driven. All automation is opt-in. The manual path is never blocked.
Three roles. One system.
Knows what to do next.
Sees guidelines as step-by-step flows. Does not know it is DMN under the hood. Does not need to. Experiences it as clarity: the right action, at the right time, with the right context.
Compliance without overhead.
Sees guideline adherence, onboarding quality, institutional knowledge. New staff follow the pathway from day one. The department's expertise is in the system, not in the heads of individuals.
Impact, measured.
Sees which departments use their guidelines, which version they follow, and receives structured feedback. For the first time: a closed loop from publication to clinical practice.
Others sell the fishing rod.
We bring the fish.
We do not sell a platform and walk away. We come to the department, model the workflow, integrate the guidelines, train the staff - and offer to maintain it. Or we teach you to do it yourself. Your choice.
| WHAT OTHERS DO | WHAT WE DO | |
|---|---|---|
| Delivery model | "Here is a platform. Model it yourself." | We come to your department and model it with you. |
| Domain knowledge | Software expertise | Clinical and technical. Physicians who build systems. |
| Guidelines | Your responsibility | We track, transform, validate, version, and notify. |
| Maintenance | Your responsibility | We train your staff - or maintain it for you. |
| Patient data | Usually required | None. Zero GDPR exposure. No IT approval needed. |
| Vendor lock-in | Proprietary formats | Open standards. Export everything. Leave anytime. |
| Deployment | Months of integration | Operational from day one. No infrastructure required. |
Humans build.
Machines assist.
Everything is auditable.
We are not an AI company. We are a company that believes intelligence should be auditable. DeOS enables physicians and administrators to take complex clinical processes and make them simple - structured pathways anyone can follow, verify, and trust. At every step, AI can accelerate and assist. But the human remains in control, and every decision can be traced, verified, and audited.
"For us, THIS is what AI should be."
Built in Denmark. Already modeling pathways with a Danish surgical department.
