Nessesity · for value-based care
Paid for outcomes? Sharpen your decision-making.
A clinical-reasoning tool that verifies the correctness of your diagnostic reasoning by comparing it against current scientific evidence.
scrollOur mission · A HealthyNess system
"Help every doctor be confident in their decisions, backed by current clinical evidence."
Nessesity™
What it is
Be confident in your decisions.
Reached a diagnostic conclusion? Nessesity verifies the correctness or completeness of your approach, or points you to current scientific recommendations.
A real-time second opinion
It assesses your clinical reasoning and flags any possible mismatch with current clinical practice.
Linked to the relevant citations
Guaranteed, updated medical sources and guidelines.
A check on the correctness of your professional approach
Automatic anonymization before the verification starts. The engine assesses only the correctness of the reasoning.
Education
Gently keeps doctors up to date with relevant medical practices.
Why we built it
Where's the problem?
The decision is individual
Every doctor works with a differential diagnosis; which way the workup goes is purely individual. A consultation helps confirm the chosen path is correct.
The science keeps moving past us
Guidelines keep being refined in a fast-moving field. You need to stay informed about them in real time.
Publicly available search
Searching in chatbots is highly misleading. The sources aren't relevant, and they don't reason within a healthcare provider's context.
With Nessesity
Be confident in your decisions.
You state your position
Put your plan as a topic-level question. It's automatically anonymized before the check begins.
Stress-tests your reasoning
Nessesity searches the expert dataset and assesses the correctness and completeness of your approach. The engine evaluates the reasoning, not the patient.
You review the second opinion
Every point comes with its source and a link to current guidelines, including where your approach holds up.
You decide with confidence
You decide confident you've considered the other side and that your approach aligns with current evidence. The judgment stays yours.
A real-time second opinion.
Reviews your clinical reasoning and flags possible inconsistencies with current evidence, saving time.
Evidence
Graded, sourced, checkable.
Every counter-point is weighed by the strength of evidence behind it and traced to a named source, international and Czech.
Evidence tiers · ranked
| I | Guideline | Society & national guidance, the strongest tier |
| II | Systematic review | Pooled, appraised evidence |
| III | Randomised trial | Single-trial evidence |
| IV | Observational | Lowest weight, flagged as such |
The expert dataset · international & Czech
Always current
"Medicine constantly moves forward, and we continuously update our sources. When, for example, a new epidemiological or other health risk emerges, it is automatically taken into account by our system."
Pavel Hronek
It doesn't relate to a specific patient
It relates to the diagnostic–therapeutic approach you are considering at that moment. Automatic anonymisation removes the risk of a second opinion being given undue weight in any particular case. The physician decides whether the second opinion helps in reaching the diagnosis, or not.
Why it matters now
Built for value-based care.
"Under the leadership of director Ivan Duškov, VZP is moving toward value-based healthcare: paying for outcomes of care, not the volume of procedures."
Zdravotnický deník, 2026
Czech healthcare is moving to reward results: a bonus for the right outcome, less for complications and repeat care. That puts new weight on getting the decision right the first time, and being able to show you did. Nessesity helps you verify your findings against the best available evidence and keeps an auditable trail of every call. Let us help you earn the outcome and stand behind it.
A second opinion raises your confidence that the diagnostic reasoning is sound.
Every verification leaves a trace — traceable and evidenced at any time.
Certainty in decisions cuts the number of check-ups, ordered tests, and ineffective prescribing.
For whom
For the doctor accountable for their decision.
Doctors in everyday practice who need to be certain their approach is correct, grounded in relevant medical practices.
Primary — the GP
The patient's first contact with the health system. Carries the greatest share of the need for diagnostic accuracy — and for the patient's onward path through the system.
ČLS JEP · point of care
Outpatient specialist
Develops and refines diagnostic and therapeutic approaches within their specialty. Here, effectiveness heads off hospitalisation.
Cardiology · Oncology · 13+
Prescription
An area often over-used when the diagnosis is uncertain. Genuine need — and demonstrated drug efficacy — is what matters.

Boundaries
What Nessesity doesn't do.
For full clarity we state publicly what the product is not. The same scope applies in our terms and every partner contract.
It gives no diagnosis, final or preliminary, to a clinician or anyone else.
No treatment plan, dosing or therapeutic instruction. It works from evidence, not orders.
It reasons about topics and populations, never an identifiable individual or case.
By design it stays outside MDR scope: a reasoning tool, not a regulated diagnostic.
It is not for acute or time-critical situations. Clinical urgency is handled by clinicians.
It shows you the second opinion. The assessment and the decision always stay yours.
Data security
Your data is safe. By design.
Nessesity is built so there's almost nothing sensitive to hold in the first place, and what exists is locked down to European banking-grade standards.
-
No patient data, ever
The firewall blocks anything identifiable before the engine runs. There's no case data to leak, because none is ever accepted.
-
Encrypted end to end
Everything is encrypted in transit and at rest, to the standards used by the banking sector.
-
EU-resident & GDPR
All processing happens exclusively within the EU, in full compliance with GDPR and healthcare data rules.
