MODS stands for what?

• A. Major Organ Dysfunction Syndrome
• B. Multi-Organ Syndrome
• C. Multi-Organ Dysfunction Syndrome
• D. Major Organ Dysfunction System

Answer: (C)

MODS describes a situation where two or more organ systems begin to fail to maintain homeostasis after a severe insult, such as sepsis, trauma, or major illness. The term emphasizes dysfunction spreading across multiple organs, not just involvement of several organs. That’s why the standard and correct expansion is Multi-Organ Dysfunction Syndrome—the phrase used in medical practice and exams.

The other phrasings aren’t used because they either replace dysfunction with another word or mislabel the concept. Major Organ Dysfunction Syndrome uses “major” instead of “multi,” which isn’t the established term. Multi-Organ Syndrome omits the key idea of dysfunction, implying involvement without the functional failure central to MODS. Major Organ Dysfunction System uses “system” rather than “syndrome” and still changes the meaning away from the recognized term.
