Advice/Help required

Hi there, Im working on a project where I need to get snomed data in the form of json. The data I want to bring back is a list of subjects like so:-

Taxonomy CommunicateAction Communication and information management Event Awards Conferences and meetings Webinar Media Publishing Social networking Health communication and promotion DiagnosticProcedure Diagnosis Diagnostic errors Diagnostic techniques and procedures Differential diagnosis Prognosis Drug Medicines Pharmaceutical preparations Biosimilar pharmaceuticals Combination products Complementary and alternative medicines Homeopathy Dosage forms Capsules

etc . Can I use this query service to bring back this data or is there some website I can go to and just download a file?

Much appreciated

Hello. This project is for querying the content within the SNOMED CT ontology which is browsable here. The information you have requested does not seem to align well with the content available. Closing this ticket for now but feel free to reopen it if you have a more specific question. Thanks.

Hi @mikebhart, thanks for providing more information about your requirements.

I would recommend:

• using the SNOMED Browser to find the most general concepts align with your requirements
  • For example 103693007 | Diagnostic procedure (procedure) | and 373873005 | Pharmaceutical / biologic product (product) |
• You could then use the snomed-query-service to fetch the concepts within each of these areas using an ECL (Expression Constraint Language) query.
  • Load a SNOMED CT release by following the readme, bear in mind that Java 8 is required at the moment to run the jar.
  • For example fetch all descendants and self of 103693007 | Diagnostic procedure (procedure) | using the ECL <<103693007 like this: http://localhost:8080/concepts?ecQuery=%3C%3C103693007

Concepts are fetched 1,000 at a time. The response has pagination using the offset parameter.

FSN vs PT This project only currently supports fetching the concept id and FSN or Fully Specified Name of a concept. This is the most concise name but it's often not the name used by clinicians or in medical records so the usefulness depends on your use-case.

Using Snowstorm instead Running ECL against the Snowstorm terminology server also gives you the PT or Preferred Term. This may be more helpful. e.g. https://snowstorm.ihtsdotools.org/snowstorm/snomed-ct/MAIN/2020-07-31/concepts?limit=1000&ecl=%3C%3C103693007 The public snowstorm instance has rate limiting so requests will be blocked from scripts making requests too quickly.

I hope this helps!

kind regards, Kai Kewley
