Company Overview

Turnstone LTD is a specialized healthcare IT and life sciences consultancy providing expert-level data engineering and informatics solutions. We bridge the gap between complex clinical data sources and standardized research environments. Led by a veteran OMOP Subject Matter Expert with deep experience in federal health projects (DHA/DaVINCI), we provide the technical architecture and tools necessary for high-fidelity clinical data harmonization and value set management.

Core Competencies

  • Standardized Health Data Architectures: Expert implementation of the OMOP Common Data Model (CDM) and HL7 FHIR standards.
  • Clinical Value Set Management: Development of advanced, version-controlled medical code set builders integrating SNOMED-CT, LOINC, RxNorm, and ICD-10.
  • Health Data Engineering: Designing robust ETL pipelines (Azure stack) for large-scale clinical data ingestion and harmonization.
  • Federal Health Strategy: Extensive experience supporting the Defense Health Agency (DHA) and the DaVINCI project with secure, compliant data environments.
  • Terminology Services: Automated integration of multi-terminology updates with proactive impact analysis for research cohorts.

Past Performance

  • Defense Health Agency (DHA) — DaVINCI Project: Served as the lead OMOP SME for several years, overseeing complex data mapping and engineering for federal healthcare initiatives.
  • Clinical Research Tool Development: Designed and deployed the Meridian Medical Value Set Builder, a proprietary application for managing clinical ontologies with full provenance and versioning (Requirement 10.6 compliant).
  • Private Sector Consultation: Provided technical informatics strategy for major life sciences organizations including Pfizer and IQVIA.

Differentiators

  • Requirement 10.6 Ready: Our proprietary Meridian platform specifically addresses the NIH requirement for automated integration, multi-terminology updates, and versioned code set tracking.
  • "Problem-Solver" Methodology: We prioritize low-bloat, high-efficiency architectures over pedantic, rigid frameworks, allowing for faster deployment in complex development environments.
  • Niche Domain Expertise: Rare combination of deep OMOP/UMLS terminology knowledge paired with modern Azure-native development skills (React, Vite, Azure SQL).
