The concept of and approach to multiple organ dysfunction syndrome (MODS), also known as progressive systems failure, multiple organ failure, and multiple system organ failure, have evolved over the last decade. Characterized by progressive but potentially reversible tissue damage and dysfunction of two or more organ systems that arise after a significant physiologic insult and its subsequent management, MODS evolves in the wake of a profound disruption of systemic homeostasis. Pre-existing illness, nutritional status, hospital course, and genetic variation all lead to the development of organ dysfunction in patients exposed to these risk factors. The ultimate outcome from MODS is influenced not only by a patient’s genetic and biological predisposition but also by specific management principles practiced by intensivists. This review details the clinical definitions, quantification, prevention, evaluation, support, and outcomes of organ dysfunction. A figure shows the increasing severity of organ dysfunction correlated with increasing intensive care unit mortality, and an algorithm details the approach to MODS. Tables list risk factors and prognosis for MODS, the multiple organ dysfunction (MOD) score, the sequential organ failure assessment (SOFA) score, intensive care unit interventions that reduce mortality or attenuate organ dysfunction along with unproven or disproven ICU interventions, and the temporal evolution of MODS.
This review contains 1 figure, 7 tables, and 159 references.
