MODS is defined as?

MODS is defined as?

• A. Dysfunction of a single organ
• B. Progressive dysfunction of two or more organ systems
• C. Recovery after organ support
• D. Localised organ damage

Answer: (B)

Multisystem organ dysfunction syndrome involves progressive dysfunction of two or more organ systems after a severe insult, driven by a systemic inflammatory response that disrupts microcirculation and perfusion. The defining feature is that multiple organs fail or deteriorate, not just one area. In practice, you might see respiratory failure with low oxygenation, kidney injury with reduced urine output, liver dysfunction, cardiovascular instability, altered mental status, or coagulation abnormalities—all developing or worsening over time. This multi-system involvement signals a high risk of mortality and requires addressing the underlying cause while providing supportive care for each affected system. The other scenarios describe issues limited to a single organ, localized damage, or recovery after support, which don’t capture the spreading, multi-organ nature of MODS.
