What percentage of the
general public has even heard
of sepsis?
A. 19%
B. 31%
C. 43%
D. 55%
E. 67%
However, most people could not
place the correct context
Sepsis
• “Septicemia is a state of microbial
invasion from a portal of entry into the
bloodstream which causes signs of
illness.“
» Schottmueller, 1914
Sepsis
• Admissions for sepsis in 2000
621,000
• Admissions for sepsis in 2008
1,141,000
• Mortality rate of 28-50%
– http://www.cdc.gov/sepsis/basic/qa.html
Sepsis
• Contributed to 1 in every 2 to 3 hospital
deaths, and most of these patients were
admitted with sepsis
» JAMA July 2, 2014 Volume 312, Number 1, Page 90
• The most expensive hospital condition,
costing over $24 billion per year
» Statistical Brief #204, May, 2016
» Healthcare Cost and Utilization Project
Sepsis
• 40% of total ICU expenditure
– Davies, et al. 14th Annual Congress of the
European Society of Intensive Care
Medicine 2001
• The number of sepsis patients is
projected to increase by 1.5% per year
– Angus, et al. Crit Care Med 2001
Hospital Readmissions
• Patients who survived sepsis to be discharged
from the hospital
• More than 40% were readmitted within 90 days
• Half of these readmissions were deemed possibly
preventable
– JAMA March 10, 2015 Volume 313, Number 10
Hospital Readmissions
• Patients who survived sepsis to be discharged
from the hospital
– The majority of unplanned hospital readmissions after
sepsis are due to an infection and identified that many
rehospitalized survivors present through the ED with
recurrent sepsis
– Crit Care Med March 2016 • Volume 44 • Number 3
– Sepsis is a leading contributor to excess healthcare
costs due to hospital readmissions
– Crit Care Med October 2015 • Volume 43 • Number 10
Hospital Readmissions
• Index admission for heart failure
– Pneumonia & sepsis are frequent reasons for
readmission
• Index admission for acute myocardial infarction
– Pneumonia & sepsis
• Index admission for pneumonia
– Recurrent pneumonia, sepsis, C. diff infection
– JAMA January 23/30, 2013—Vol 309, No. 4

Surviving Sepsis
• Surviving Sepsis Campaign (2002)
– Society of Critical Care Medicine
– European Society of Intensive Care Medicine
– International Sepsis Forum
• Surviving Sepsis Guidelines
– http://www.survivingsepsis.org/
Surviving Sepsis
• Routine screening of at-risk patients
• Obtain appropriate cultures & imaging
• The administration of effective intravenous
antimicrobials within the first hour of recognition
• Source Control
• Initial Resuscitation
Lactate
• “Measuring lactate levels
can risk stratify patients
with suspected sepsis, to
prompt aggressive early
treatment, and help
monitor the impact of
therapy”
– Chee C et al. Crit Care Med 2015
Lactate
• “The prognostic value of
lactate levels exceeds that of
blood pressure.”
• “Many studies have
confirmed the association
between initial serum
lactate level and mortality
independently of clinical
signs of organ dysfunction”
– Cecconi M, et al. Intensive Care
Med 2014;40:1795
• “In this multicenter, openlabel randomized controlled
study, lactate monitoring
during the first 8 hours of
ICU admission, aimed at
reducing lactate levels by at
least 20% per 2 hours,
significantly reduced ICU
length of stay and also ICU
and hospital mortality”
– Jansen TC, et al. Am J Respir
Crit Care Med 2010;182:752
Initial Resuscitation
• “We recommend the protocolized,
quantitative resuscitation of patients with
sepsis-induced tissue hypoperfusion”
– Surviving Sepsis Guidelines
Initial Resuscitation
• “We suggest targeting resuscitation to
normalize lactate in patients with elevated
lactate levels as a marker of tissue
hypoperfusion”
– Surviving Sepsis Guidelines
Surviving Sepsis
• TIME SENSITIVE!
– Identify patients early in their course
– Administer antibiotics promptly
– Fluid resuscitation—fast & furious
The minimum volume of the initial fluid
resuscitation for the septic patient is:
A. 250 ml
B. 500 ml
C. 1000 ml
D. 10 ml/kg
E. 30 ml/kg
Surviving Sepsis
3-hour bundle
• Measure lactate level
• Draw blood cultures
• Administer broad
spectrum antibiotics
• Administer 30 ml/kg
crystalloid fluid bolus
6-hour bundle
• If persistent
hypotension after
initial fluid
resuscitation, then:
– Add vasopressors
– Measure CVP, SvO2
– Remeasure lactate
Surviving Sepsis
• Compliance with the Surviving Sepsis
Campaign bundles is associated with
improved mortality

– Levy MM et al. Intensive Care Med 2010;36:222
National Inpatient Quality Measures
• Within 3 hours of identification of severe sepsis:
– Initial lactate level measurement
– Broad spectrum or other antibiotics administered
– Blood cultures drawn prior to antibiotics
• Within 6 hours:
– Repeat lactate measurement if initially elevated

Definitions
• Sepsis
– SIRS + infection
• Severe sepsis
– SIRS + infection + new
organ dysfunction
• Septic shock
– Impaired perfusion
despite adequate fluid
resuscitation
• Many patients with severe
sepsis do not have SIRS
• Many patients with severe
sepsis do not initially have
any obvious organ
dysfunction
• Infection + new organ
dysfunction can occur in the
absence of severe sepsis
The Third International Consensus
Definitions for Sepsis and Septic Shock
(Sepsis-3)
• Definitions of sepsis, severe sepsis, and septic
shock revisited
• Fair sensitivity & poor specificity of SIRS
• Recognition of inflammation as a normal
response to infection
– JAMA February 23, 2016 Volume 315, Number 8
Key Concepts
• Difficult to distinguish between “normal”
and “dysregulated” inflammatory response
• Organ dysfunction may not be obvious
• Sepsis might not be the cause of organ
dysfunction
Key Concepts
• No “gold standard” diagnostic test for sepsis
• Change in approach to screening patients for
sepsis
– New infectionlook for organ dysfunction
– New or worsening organ dysfunctionlook for
infection
Proposed Definitions
• Sepsis is defined as life-threatening organ
dysfunction caused by a dysregulated host
response to infection
– Organ dysfunction can be identified as an acute
change in total SOFA score ≥2 points consequent
to the infection
• JAMA 2016;315(8):801-810
Proposed Definitions
• Septic shock is defined as a subset of sepsis
in which underlying circulatory and cellular
metabolism abnormalities are profound
enough to substantially increase mortality
– Hypotension requiring vasopressor therapy to
maintain mean BP 65mmHg or greater and having
a serum lactate level greater than 2 mmol/L after
adequate fluid resuscitation
• JAMA 2016;315(8):775-787
