Which of the following statements is true regarding SNOMED CT?

The statement regarding SNOMED CT concepts having two parents is accurate because SNOMED CT allows for a hierarchy where a single concept can indeed belong to multiple parent classifications. This feature, known as polyhierarchy, is essential for representing complex relationships between clinical terms and concepts, making it possible for the same concept to be relevant in different contexts or clinical situations. This flexibility supports a more nuanced description of healthcare information, reflecting the complexity of clinical practice.

The other options do not accurately represent the characteristics or history of SNOMED CT. While it is true that SNOMED CT contains a vast number of concepts far exceeding 30,000, it actually encompasses over 300,000 concepts, making the claim in the second statement incorrect. The third statement about being the most comprehensive clinical classification is subjective, as there are other coding systems that also claim a high level of comprehensiveness. Lastly, the organization responsible for the development and maintenance of SNOMED CT is the International Health Terminology Standards Development Organisation (IHTSDO), now known as SNOMED International, which conveys a slightly different context regarding the development process.
