Notes

Two Sub-Workstreams of 5.2

1. Applying ANF to clinical narratives for health factors

2. Quality Assurance of terminology like SNOMED and LOINC

ANF in Clinical Narratives

• Need to define what a chunk is and how it can be used

• All of our work should be use-case driven i.e. ultimately tailored for the end-user

Quality Assurance

• Technical Debt: the amount of time and effort needed to fix a problem

• Intermediate Primitive: A concept that is not fully defined, but has parents and children that are fully defined

  • Intermediate primitives are an indicator of a problem in the logical classification structure

  • They can block classification of concepts lower in the hierarchy

• SNOMED has intermediate primitives that require a certain level of technical debt to resolve

  • This is an example of a problem that can be addressed with quality assurance processes

• Quality Assurance Process:

  • Define problematic pattern

  • Identify qualifying concepts that meet definition

  • Evaluate whether qualifying concepts are false positives

  • Calculate amount of hours and minutes required to resolve problematic concepts
