The information problem

Health data is heterogeneous because health itself is contextual.

Some information is structured. Some arrives as a laboratory result, prescription, study, report, or form. Some is spoken during a consultation. Some is an observation from a patient, family member, animal owner, teacher, therapist, physician, or veterinarian. Some is a generated summary of something else.

A useful system should not flatten these into indistinguishable text. It should preserve enough structure to answer basic questions about every important piece of information.

Where did it come from?

Document, consultation, professional note, owner or family observation, imported result, transcription, or generated summary.

When was it true?

Creation time is not always the same as the clinical time to which the information applies.

Who contributed it?

Authorship and role matter when multiple people participate in care.

What is it connected to?

Events, medications, symptoms, results, plans, documents, follow-up, and previous history give a record meaning.

Longitudinal information

Instead of treating the current value as the whole truth, longitudinal systems preserve change. This is relevant to SmartMatrix, Animal Care, and rAIn: the value is not only what a record says today but how the current state relates to what was observed before.

Interoperability research

The work has included examination of standards and terminology systems used to exchange or normalize healthcare information, plus the question of how much of that ecosystem translates to veterinary medicine.

HL7 / FHIR

Studied as modern healthcare interoperability approaches for exchanging structured clinical information and resources.

C-CDA

Explored in relation to structured clinical documents and continuity-oriented information exchange.

LOINC

Considered for standardized identification of laboratory and clinical observations.

SNOMED CT Veterinary Extension

Relevant to the question of veterinary-specific terminology and the limits of directly reusing human-health models.

Research scope: listing these standards means they have been explored as architecture/interoperability references. It does not mean every Unexpectech health project currently implements them.

Retrieval before generation

Artificial intelligence becomes useful in health when it can summarize, explain, organize, translate, or connect information without silently replacing the underlying record. The preferred architecture is therefore evidence-first.

01User asks a contextual question
02Retrieve authorized evidence
03Preserve source + event context
04Generate explanation or summary

The system should distinguish retrieved information, human observations, generated summaries, and model inferences. If authorized context is insufficient, “there is not enough information” is a valid and often preferable outcome.

rAIn as a concrete contextual design

rAIn provides the most detailed design example of this approach. Its health workflow connects appointments, prepared questions, event capture, audio, transcription, structured summaries, extracted medications/dates/decisions/follow-up, documents, previous events, permissions, and later natural-language questions.

The rAIn design also treats consent, permissions by domain and event, traceability, access logs, revocation, retention, export, and deletion as part of the architecture rather than simply UI settings.

Core principle: AI-generated language should never silently become medical fact. The relationship between an answer and the information used to produce it should remain visible whenever that relationship matters.
