Many of the affected concepts are not modeled according to the pattern shown in the solution section below. These will be editied to conform to the proposed pattern.
4. Solution
- A new qualifier value of "Post-natal" will be created to aggregate the periods of life that would be used to define "Acquired" conditions.
- Move the following concepts under “Postnatal period”:
- Adolesence
- Adulthood
- Childhood
- Infancy
- Old age
- All concepts that current explicitly state "acquired" in their FSN would have a new relationship OCCURRENCE = Post-natal period (qualifier value) added to the defining relationship group(s). This will allow many of the currently primitive concepts to become sufficiently defined resutling in a richer set of inferences.
- When revising modeling of acquired disorders, remove any “Acquired” morphologies and replace with general parent morphology. E.g. Replace “acquired deformity” with “deformity”.
The general pattern for revising the affected concepts is shown in the diagram below:
5. Construction
Some identified issues;
- Some disorders that are developmental but manifest later in life are classified as acquired.
- Missing some “musculoskeletal structure of X” concepts for deformities
- Due to existence of primitive concepts, there is a need to inactivate:
- 367335002 - Claw hand - acquired (finding) DUPLICATE TO 367393006 - Acquired claw hand (disorder)
- Acquired forearm deformity, excluding fingers DUPLICATE to “Acquired forearm deformity as the fingers are not anatomically part of the forearm.
- Inactivate 45402003 – Juvenile disease (finding) as ambiguous.
- Add new body structure “Musculoskeletal structure of forearm (body structure)”
- Periods of life assignment where the onset is at one stage of life but persists throughout the rest of life. How to assign OCCURRENCE?
