- A new qualifier value of "Period of life beginning after birth and ending before death (qualifier value)" will be created to aggregate the periods of life that would be used to define "Acquired" conditions.
- Move the following concepts under this new grouper:
- Adolesence
- Adulthood
- Middle age
- Childhood
- Infancy
- Old age
- All concepts that current explicitly state "acquired" in their FSN or in a "synonym" would have a new relationship "OCCURRENCE = Period of life beginning after birth and ending before death (qualifier value)" added to the defining relationship group(s), if an OCCURRENCE relationship does not already exist. This will allow many of the currently primitive concepts to become sufficiently defined, resulting 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”.
- As the use of the "Acquired X (morphologic abnormality)" concepts is eliminated, inactive the morphology concepts.
