## Clinical data warehouses · 20% structured data. What about the other 80%?

Clinical information goes beyond the fields in your databases.

Much medical knowledge lies dormant in documents. CLARYS Intelligence makes it usable, structured and traceable, without adding new sources.

Most clinical information sits in documents. Make it usable.

- **More variables.** Conditions, complications and social factors drawn from reports, beyond coded data.
- **Context preserved.** Affirmed, negated, suspected: every data point keeps its meaning and its source.
- **Your CDW stays yours.** CLARYS Intelligence fits into your existing pipelines without replacing them.

## The problem · Information missing from the coding is not missing information.

Your warehouses mainly use coded data. Conditions, complications and social factors described in free text slip through the analysis.

## The value for your CDW · More clinical information. A more complete view. More relevant analyses.

- **Enrich variables.** Information drawn from documents, beyond coded data.
- **Preserve clinical context.** Affirmed, negated, suspected: every mention read for what it is.
- **Quality, documented.** Precision, recall and coverage measured on your corpus.
- **Maintain traceability.** Each variable tied to its supporting passage.

## Semantic interoperability · Exchanging data is not enough. Its meaning must be shared too.

Formats enable exchange. Terminologies align concepts. CLARYS Intelligence adds clinical context.

- **FHIR for exchange.** The formats your ecosystem already uses.
- **Terminologies for consistency.** Expressions aligned with reference terminologies such as SNOMED CT.
- **Intelligence for context.** Negation, suspicion and traceability preserved.
- **Longitudinal for pathways.** Dated information, linked to events.

## Use cases · Enrich your data. Broaden your horizons.

- **Study feasibility.** Find eligible patients in clinical reports.
- **Enriched cohorts.** Inclusion criteria enriched by free text.
- **Real-world data.** Better-characterized comorbidities, treatments and events.
- **Longitudinal analyses.** Event sequences ready for care pathway studies.

## Your warehouse, our intelligence · Add clinical understanding to your existing infrastructure.

CLARYS Intelligence makes previously out-of-reach information usable for research, population characterization and care pathway analysis.

1. **Access the content.** Through your systems and preparation pipelines.
2. **Extract and contextualize.** Concepts, context, terminologies.
3. **Produce traceable data.** Linked to their sources, ready for validation.
4. **Power your use cases.** Warehouses, research, analytics applications.

The same warehouse. Broader clinical knowledge.

## Integration architecture · Your CDW organizes the data. CLARYS Intelligence extends its clinical reach.

### Accessible clinical content

- Reports
- Letters
- Clinical notes

Your data preparation pipelines

- **CLARYS Intelligence.** Extraction · Context · Normalization · Traceability
- **Your existing CDW.** Enriched, traceable variables, integrated into your models

- **Research.** Feasibility and real-world studies
- **Cohorts.** Structured and text-based criteria
- **Applications.** Reusable clinical context

CLARYS Intelligence sits between your content and your warehouse, without replacing your pipelines.

## Getting started · One clinical question. Data to rediscover. Value to measure.

A clinical question, a representative corpus: let’s identify what your structured data misses and measure the benefit for your CDW.

## Clinical knowledge, largely held in documents

Directly usable in information systems.

Structured data

Reports, PDFs, clinical notes and free text.

Document-based data
