The allergy project has utilised SDP (Structure/Disposition/Process) model for reorganisation of hierarchical structure for allergy related content in SNOMED CT. NOTE: |Allergy to X| modeling and terming normalization will be performed to a great extent using script development. Input to formalize |Allergy to X| modeling and terming guidelines was provided by internal resources plus Bruce Goldberg (Consultant Terminologist as SME). Review/publishing of updated content to be performed by internal resources (assumed to be primarily Toni Morrison and Yongsheng Gao; Bruce Goldberg will be consulted as needed for exceptions and irregularities).
Reorganization of structure for allergy related content
Allergy to X / allergic reaction / allergic disorder - three patterns only first pattern allergy to x being worked on
Member Priority -Allergies – content, subsets, implementation guidance and governance
Interoperable deployment of SNOMED CT in support of Electronic Health Record (EHR) adverse sensitivity data (which encompasses allergy, non-allergic hypersensitivity and intolerance) is inconsistent and fails to support interoperability across IHTSDO member realms. This arises due to confusion regarding the scope and definition of adverse sensitivity data, uncertainty regarding the reference models for defining relevant data records and inconsistency in guidance for the appropriate value sets from SNOMED CT that should populate those records.
This allergy project will:
• extend previous (and current) IHTSDO work on definitions of adverse sensitivity events,
• survey and summarize the relevant interoperability standards,
• advise the IHTSDO community regarding best practice deployment of allergy data within the EHR
• Identify the SNOMED CT resets (value sets) that would constitute best practice for use in electronic health records.
Several Standards Development Organizations (SDOs) such as HL7 and epSOS have also provided some material to assist implementers, however without formal or informal collaboration with IHTSDO. A more formal arrangement in collaborative efforts and/or guidance would be beneficial for implementers of SNOMED CT.
|1||Implementation of the new Allergy/hypersensitivity concept model|
Implement the new concept model for allergy model//hypersensitivity by template based batch changes and manual changes to modeling and descriptions for 2000 concepts
