The Data Imperative
(Continued)
Unstructured or Incompatible Data Formats Legacy data is often unstructured, coded inconsistently, or stored in proprietary formats that inhibit interoperability. Without standardisation, this data cannot be integrated into modern, standards-based systems or used effectively for analytics and population health management. Stalis’ data transformation and mapping methodologies convert disparate legacy data into structured, standards-aligned formats using internationally recognised terminologies such as SNOMED CT, ICD-10, and LOINC, and interoperability frameworks such as HL7 FHIR. This ensures that information is portable, usable, and future-proof across the HSE’s regional and national systems. Loss of Clinical Context and Metadata Beyond the data itself, many legacy systems contain contextual information, including timestamps, clinician notes, document attachments, and audit trails. These important datasets provide the necessary clinical and legal provenance of care. If this data is not preserved during migration, the clinical record becomes incomplete and its evidential value diminished. Stalis’ extraction and transformation processes maintain the full clinical narrative and metadata associated with every record, ensuring the integrity of the data and its continued relevance within the new system. Disruption to Operations and Change Fatigue EHR projects often place significant strain on already stretched IT and clinical teams. Manual extraction and validation processes consume time and introduce operational risk, while lack of visibility into data readiness can delay go-lives. Stalis provides fully managed, end-to-end migration programmes that integrate seamlessly with vendor and system integrator timelines, reducing disruption to business-as-usual activities. Our project teams work alongside clinical and technical stakeholders to provide predictable delivery, transparent reporting, and measurable assurance at every stage.
Stalis: Delivering Data that Follows the Patient
By combining technical precision, clinical understanding, and governance excellence, Stalis ensures that data not only transfers safely, but retains its clinical meaning, compliance integrity, and operational value in the digital environment. Our mission is to ensure that data follows the patient safely and meaningfully into the future, therefore forming the foundation of trust, quality, and insight on which Ireland’s National EHR programme will depend.
