Audience Participation! The last decade has seen a decrease in the case fatality rate from sepsis. However, over that same timeframe, the incidence of sepsis (and total annual mortality) continues to increase because of which of the following: • Better education about and recognition of sepsis • An aging population with more comorbid conditions and risk factors • Better reporting of cases of sepsis • All of the above
Sepsis Resuscitation Early Goal-Directed Therapy (EGDT) and The Rivers Protocol
Quick Tangent - Infection Control Mortality Ferrer R, Martin-Loeches I, Phillips G, Osborn TM, et al. CritCare Med 2014;42(8):1749-55.
Why EGDT? • Case mortality rates for severe sepsis and septic shock unacceptably high • “Late” interventions (after admission to intensive care unit) routinely show no benefit • Routine physical assessment has inadequate sensitivity to detect ongoing tissue hypoxia • Variability in the assessment and resuscitation of septic patients Rivers E, Nguyen B, Havstad S, Ressler J, et al. N Engl J Med 2001;345:1368-77.

Audience Participation! Which statement about the goals of the original Rivers Protocol for sepsis resuscitation is NOT accurate? • The MAP goal targeted by Rivers should have been higher • CVP might not be a valid assessment of fluid responsiveness when used in isolation • Septic patients do not require a transfusion threshold of HCT > 30% for oxygen delivery • ScVO2 can be replaced by lactate to monitor sepsis resuscitation

Primary Outcomes • No statistically significant difference in primary or secondary outcomes in any of the three studies • None of the trials met pre-defined power Mouncey P, Osborn T, Power S, Harrison D, et al. N Engl J Med 2015;372:1301-11. PROCESS Investigators. N Engl J Med 2014;370:1683-93. ARISE Investigators. N Eng J Med 2014;371:1496-506.
Resuscitation Elements Mouncey P, Osborn T, Power S, Harrison D, et al. N Engl J Med 2015;372:1301-11.
Take-Home Points • There is NO DIFFERENCE between “Usual Care” and Early Goal-Directed Therapy… BUT • The only real differences in Usual Care and EGDT were driven by changes in monitoring (CVP, ScVO2) • The key interventions driven by Usual Care (fluid volume, pressors) were similar to those in EGDT • We might not need to be quite so aggressive in patients that don’t respond to 1 liter of IV fluids, but… • Early intervention and resuscitation is STILL IMPORTANT
Surviving Sepsis Campaign • Changes to 6-hour bundle reflect recent literature • Removed requirement for CVC insertion for CVP and ScVO2 monitoring • Continuous reassessment of volume status and tissue perfusion with: • Repeated focused exam, OR • Two of the following: • CVP • ScVO2 • Bedside cardiovascular ultrasound • Dynamic assessment of fluid responsiveness http://www.survivingsepsis.org/SiteCollectionDocuments/SSC_Bundle.html
Audience Participation! Which of the following statements accurately summarizes the findings of new trials in the resuscitation of septic patients? • Resuscitation protocols do not work for the resuscitation of septic patients • The Rivers Protocol is probably more aggressive than necessary for all patients • There is no role for ScVO2 monitoring in septic patients • All of the above
SEPSIS-3 A Meaningful Redefinition of Sepsis
“Old” Sepsis Infection Sepsis Infection + SIRS • T > 38.3 or T < 36 • HR > 90 • RR > 20 or PCO2 < 32 • WBC > 12 or WBC < 4 Severe Sepsis Septic Shock Sepsis + EOD • AMS • oliguria, increased SCr • increased LFT’s • acute lung injury • lactic acidosis Severe Sepsis + Hypotension Vincent JL, Opal SM, Marshall JC, Tracey KJ. Lancet 2013;381(9868):774-5.
“Old” Sepsis • Sensitivity? • Missing 1 in 8patients with infection and organ failure • Predictive Value? Kaukonen K, Bailey M, Pilcher D, Cooper D, et al. N Engl J Med 2015;372:1629-38.
“New” Sepsis – SEPSIS-3 Singer M, Deutschman C, Seymour C, Shankar-Hari M, et al. JAMA 2016;315(8):801-10.
SOFA and Organ Dysfunction Singer M, Deutschman C, Seymour C, Shankar-Hari M, et al. JAMA 2016;315(8):801-10.
Limitations of SEPSIS-3 • Still subjective • SOFA and qSOFA are mortality predictors, not objective tests for sepsis • “Suspected Infection” remains elusive • Still non-specific • Can meet SOFA criteria without having sepsis • Might not be more sensitive • Not prospectively validated
Audience Participation Which of the following is true of the new definition of sepsis (SEPSIS-3)? • SEPSIS-3 is more specific for identification of septic patients • SEPSIS-3 is more sensitive for the identification of septic patients • SEPSIS-3 has better defined prognostic implications for septic patients • All I can remember is Justin Bieber
Conclusions • Sepsis is characterized by a dysregulated response of the immune system with resultant tissue damage • Care of the septic patient is governed by two principles: infection control and resuscitation • Recent data suggests that resuscitation efforts might not have to be as aggressive as we once thought • The new definition of sepsis reflects the importance of a focus on organ dysfunction
