Alchemist / Critical Care

Documentation on the data exchange format for HIC Critical Care and the Alchemist ingestion pipeline.

OMOP Person

This describes the first dataset that must be created and submitted by each site. The primary purpose of this data bundle is to:

  • Identify patients of interest and their ages.
  • Ensure that the site can set up a local ETL pipeline.
  • Ensure that files for transfer can be created successfully.
  • Ensure that data can flow all the way through to central processing.
  • Ensure that the site can receive quality evaluation reports.

While this data bundle is quite small, compliance with it will be measured very strictly, as any issues at this stage create a significant risk for further data bundles.

This data bundle requires:

  • The PERSON table with only a subset of columns populated.
    • person_id
    • person_source_value
    • Columns relating to the patient’s date of birth

The following must all be confirmed before proceeding:

  • Data can be added
  • Data can be deleted
  • Data can be updated
  • All patients are 18 years of age or over

Inclusion criteria

  • ADULT patients. Please DO NOT include patients who are under 18 on the day of their ICU admission.
  • The original 7 sites should include all ADULT patients admitted to critical care areas since 1st February 2014.
  • All other sites should only include ADULT patients admitted after the date of local approval to submit data.
  • Patients admitted before 1st February 2014 (original 7 sites) or before the local date of approval (Manchester, Bristol, Marsden) should not be included.
  • DO NOT send patients who have opted-out via the National data opt-out scheme.
