• Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection.
• Often leading to organ dysfunction. • Sepsis is defined as the presence
(probable or documented) of infection together with systemic manifestations of infection.

• Sepsis should be defined as life-threatening organ dysfunction caused by a dysregulated host response to infection.
• Organ dysfunction can be represented by an increase in the Sequential Organ Failure Assessment (SOFA) score of 2 points or more, (which is associated with an in-hospital mortality greater than 10%).
• Septic shock should be defined as a subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with a greater risk of mortality than with sepsis alone.
• Term “Severe Sepsis” is redundant and unecessary

Operationalization of Clinical Criteria Identifying Patients With Sepsis and Septic ShockThe baseline Sequential [Sepsis-related] Organ Failure Assessment (SOFA) score should be assumed to be zero unless the patient is known to have preexisting (acute or chronic) organ dysfunction before the onset of infection. qSOFA indicates quick SOFA; MAP, mean arterial pressure.

• Measure Set: Sepsis Set Measure ID #: SEP-1• Performance Measure Name: Early Management
Bundle, Severe Sepsis/Septic Shock• Description: This measure focuses on adults 18 years
and older with a diagnosis of severe sepsis or septic shock. Consistent with Surviving Sepsis Campaign guidelines, it assesses measurement of lactate, obtaining blood cultures, administering broad spectrum antibiotics, fluid resuscitation, vasopressor administration, reassessment of volume status and tissue perfusion, and repeat lactate measurement. As reflected in the data elements and their definitions, the first three interventions should occur within 3 hours of presentation of severe sepsis, while the remaining interventions are expected to occur within 6 hours of presentation of septic shock.

• Age– Bimodal: highest for infants and those > 50– Increases in sepsis diagnosis highest in those > 65
• Sex– Slightly higher for males
• Comorbid illnesses– DM, CHF, ESRD, liver disease, CA, immunosuppression
• Race– 2x higher risk for AA in comparison to Caucasians– May be due in part to higher rate of comorbid condtions
(ESRD, DM)• Seasonal
– Sepsis due to respiratory illness highest in the winter

• 6. In the event of persistent hypotension after initial fluid administration (MAP < 65 mm Hg) or if initial lactate was ≥4 mmol/L, re-assess volume status and tissue perfusion and document findings according to guidance.
• 7. Re-measure lactate if initial lactate elevated.
