Clinical logic under
clinical oversight.

Dosing limits, triage criteria, and eligibility rules expressed in a language medical professionals can read, review, and govern directly.

The problem

Rules locked inside the EMR

When a medical board updates a guideline, it must be translated into EMR configuration by IT. Over time, the clinical rule becomes an IT asset that medical professionals can no longer directly inspect or govern.

Lossy translation

National guidelines written in medical terms undergo a translation into proprietary EMR configuration. Medical intent is separated from operational reality.

Historical accountability

Audits and malpractice inquiries examine decisions made years ago. Proving which rule version was active on a specific date requires forensic IT investigation.

System drift

The same eligibility check is configured differently in nursing, laboratory, and billing modules. As updates occur unevenly, these systems quietly drift out of sync.

Introducing Lemma

Separate the rules from the infrastructure

Clinical rules expressed once, in a readable format. The EMR queries the rule engine for a deterministic answer and continues its operation.

Native explainability

Every evaluation outputs step-by-step clinical reasoning. A transparent audit trail independent of the EMR's internal logs.

Temporal accuracy

Evaluates patient data against the correct historical, current, or future version of a rule based on the effective date of the event.

Direct medical oversight

A medical review board can inspect the logic directly, without relying on IT intermediaries to confirm that software reflects the clinical guideline.

Privacy by design

Lemma does not need any patient details. The language does not store any data required to evaluate rules. Clinical logic is governed without exposing sensitive information.

Why LemmaBase

Reclaim institutional capacity

Hospital IT manages information and coordinates care. It should not be the unreadable custodian of clinical intelligence.

  • Lemma is open source (Apache 2.0). Your institution owns the clinical rule definitions.
  • Medical updates deploy without weeks of EMR re-configuration and system testing.
  • Retrospective audits answered by reviewing the versioned rule, not reverse-engineering IT systems.
  • Clinical governance remains under direct medical oversight, not delegated to IT capacity.
