SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires certifi, and includes scripts (resource) components.

What problem does it solve?

Mapping product names to standardized RxNorm/OMOP concepts is time-consuming and error-prone when relying on string matching alone. This Skill consolidates semantic search results and dose form context so curators can find appropriate RxNorm concepts more efficiently and with better evidence for EXACT vs BROAD mappings.

Core Features & Use Cases

  • Semantic RxNorm lookup: Queries the Hecate semantic search API to retrieve candidate RxNorm concepts for product name queries.
  • Dose form awareness and deduplication: Matches and prints dose form definitions, deduplicates results, and surfaces concept_id, concept_name, and concept_code for downstream decision-making.
  • Extension fallback: Optionally searches RxNorm Extension with filters and guidance to avoid supplier/packaging or otherwise dubious extension concepts. Use case: mapping EMA-authorised product entries during manual curation or batch review for Sweden and Latvia datasets.

Quick Start

Use the find-concepts skill to search Hecate for candidate RxNorm concepts for "vildagliptin 50 mg oral tablet" and review the printed concept list and dose form definitions.

Frequently Asked Questions about find-concepts

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I map product names to RxNorm concepts using semantic search?▼

Map product names to RxNorm concepts by querying the Hecate semantic search API to retrieve candidate concepts, then reviewing deduplicated concept_id, concept_name, and concept_code for manual curation or batch mapping workflows.

What is the best way to find RxNorm concepts for EMA authorised products?▼

Finding RxNorm concepts for EMA authorised products involves using semantic search against the Hecate API to match drug names, returning candidate concepts and dose form definitions to support EXACT vs BROAD mapping decisions.

Can I search the RxNorm Extension for drug vocabulary mappings?▼

Yes, you can optionally search the RxNorm Extension with filters and guidance to avoid supplier or packaging concepts, returning candidate concepts suitable for mapping Swedish and Latvian authorised products during manual curation.

How does dose form matching work when mapping to OMOP vocabulary?▼

Dose form matching during OMOP vocabulary mapping works by retrieving dose form definitions alongside candidate RxNorm concepts from the Hecate API, printing them to provide context for downstream selection and accurate mapping decisions.

Do I need any specific dependencies to perform RxNorm drug mapping?▼

You need the certifi dependency installed to perform RxNorm drug mapping, ensuring secure API connections to the Hecate semantic search service for retrieving candidate concepts and dose form definitions.

Why should I use semantic search instead of string matching for RxNorm concepts?▼

Semantic search retrieves conceptually relevant RxNorm candidates where string matching fails, consolidating results with dose form context to help curators find appropriate concepts and gather evidence for EXACT vs BROAD mappings.
