Sepsis 2017Core Measures
Recognition and Management
Tom Ahrens PhD RN FAAN
� Research Scientist at Barnes-Jewish Hospital, St. Louis, MO
� No conflicts of interest to report
SEP-1
Core Measure
� Suspected infection
� 2 or more signs of SIRS
� Evidence of organ dysfunction
� Elevated lactate is one example
2
�
Time Zero
When the patient meets criteria for severe
sepsis
CMS Core Measure
� Measure Description: This measure will focus on patients aged 18 years and older
who present with symptoms of severe sepsis or septic shock. These patients will be
eligible for the 3 hour (severe sepsis) and/or 6 hour (septic shock) early management
bundle.
� Numerator Statement: If:
measure lactate level
obtain blood cultures prior to antibiotics
administer broad spectrum antibiotics
administer 30 ml/kg crystalloid for hypotension or lactate >=4 mmol/L
What is sepsis?
� Sepsis is the body’s immune system response to an infection
� Bacteria, virus, protozoan
� Instead of a localized response to an infection (like a
pneumonia), sepsis is a systemic response that can be
catastrophic
� Highest cost to US hospitals (AHRQ)
� Leading cause of death in hospitals

New Definitions
New Sepsis DefinitionqSOFA
� An alteration in mental status (not the GCS)
� A decrease in SBP of less than 100 mm Hg
� A respiratory rate > 22 bpm
�
Sequential Organ
Failure AssessmentSOFA Scores
4
Method of Predicting Outcomes in
Critically Ill Patients
� An initial SOFA score of < 9 predicted a mortality of <
33%
� A SOFA > 11 predicted mortality of 95%
SOFA
Key Differences in New Definition
� Sepsis as infection and 2 or more SIRS is now just an infection
� Severe sepsis is now sepsis
� Septic shock is� Blood lactate > 2 mmol/L despite volume resuscitation
� Hypotension that persists after fluid resuscitation and requires vasopressors
� Sepsis definition now will carry a higher risk of death and increased ICU LOS
5
Rationale for New Definition
� Based on review of 2 million patients in sepsis studies
� SIRS based on expert opinion
� SIRS should still be used when evaluating sepsis
Controversies with New
Definition
� Not a screening tool
� A better sepsis definition
� Concern is a delay in sepsis identification
6
Benefits and Barriers
� Improved� Patient identification
� Coding and reimbursement
� SOI/ROM
� Reduced mortality
� Improved compliance with bundles
� Barriers� Multidisciplinary cooperation
� Funding
� Education

The Power of Our Immune System
““““Our arsenals for fighting off bacteria are so powerful, and involve so many different defense mechanisms, that we are more in danger from them than from the invaders.

Power of the Immune SystemVaccine Schedule – Too Much?
14 Vaccines now Recommended
� What causes immune response is number of proteins
that cause reaction - Epitopes
� 100 years ago only vaccine was against smallpox
� Large virus, 200 epitope inducing proteins
� Todays 14 vaccines have 160 epitope inducing
proteins
� Immune system has to respond, immediately at birth,
millions of bacteria
� Each of these bacteria have 2-6 thousand protein
which can induce epitopes
� Within days, a human baby has 100 trillion
bacteria in and on them (we have 10 trillion cells)
A Single Cold Virus Has More
Protein Inducing Epitopes than
All Vaccinations Combined
� Given the number of B cells in the
bloodstream, the average number of
epitopes contained in a vaccine, rapidity
with which a sufficient quantity of
antibodies could be made:
� Babies could respond to 100,000 vaccines
at one time.

Determining if your
Patient is In Danger
� Establishing urgency – use of Lactate� A measure of tissue hypoxia
� Normal 1-2 mmol
� > 4 mmol with metabolic acidosis suggests tissue hypoxia
� Lactate measurements need to be repeated to evaluate if therapy is effective and if the patient is improving

Sepsis often progresses when the
host cannot contain the primary
infection
� A problem most often related to� characteristics of the microorganism,
� such as a high burden of infection � the presence of super antigens and other
virulence factors, � resistance to phagocytosis � antibiotic resistance.
Cell dysoxia
� Epithelial cells have diminished oxygen consumption� due to a depletion of nicotinamide
adenine dinucleotide (NAD)
� Concept of cell stunning or hibernation

How Do We Treat Sepsis?
Sadly, little has changed in actual treatment of sepsis in decades. The key steps are:
1) Identify the infectious organism
Blood and site cultures
2) Remove the source of the infection if possible
3) Obtain lactate
4) Initiate Antibiotics
5) If severe sepsis is present, give fluids
6) If fluids do not restore hemodynamic stability, give vasopressors
7) If pressors do not improve hemodynamics, add steroids

Trials� Key points
� Fluid administration similar in both control and experimental
groups
� Vasopressor use similar in both groups
� Antibiotics administered similarly in both groups
� Lactates obtained in both groups
� Mortality rates (<20%) is not as common outside centers with well
designed sepsis recognition/management programs
� Problems– Antibiotics and fluids given in both control and
experimental groups within 3 hours.
� Hawthorne Effect Likely
� Contamination of practice
Take away Points
� If Patients are
� identified early,
� Receive antibiotics EARLY
� receive IVF EARLY
� Then ScvO2 and CVP monitoring does not seem to add a
benefit
� BUT EGDT with ScvO2 not really tested since resuscitation
had already occurred
Hemodynamics of Sepsis
� Concept of early resuscitation� Establishing urgency – use of
Lactate
� Normal 1-2 mmol
� > 4 mmol with metabolic acidosis suggests tissue hypoxia
� Fluids with a goal� The role of mixed venous
oxyhemoglobin (ScvO2)

�CVP and PAOP should never be used in isolation� Inconsistent in revealing information about volume and flow
�Flow and pressure do not always correlate� Marik et al. Based on the results of our systematic review, we
believe that CVP should no longer be routinely measured in the ICU, operating room, or emergency department.

Measurement
Non invasive CO/SV measurement
Diagnostics
� Cultures as clinically appropriate before antimicrobial therapy
if no significant delay (> 45 mins) in the start of antimicrobial(s)
(grade 1C). At least 2 sets of blood cultures (both aerobic and
anaerobic bottles) be obtained before antimicrobial therapy
with at least 1 drawn percutaneously and 1 drawn through
each vascular access device, unless the device was recently
(<48 hrs) inserted (grade 1C).
� Imaging studies performed promptly to confirm a potential
source of infection (UG).
23
Antibiotics
� Administration of effective intravenous antimicrobials within the first hour of
recognition of septic shock (grade 1B) and severe sepsis without septic shock
(grade 1C) as the goal of therapy.
� Broad spectrum antibiotics should be initiated
� Initial empiric anti-infective therapy of one or more drugs that have activity
against all likely pathogens and that penetrate in adequate concentrations into
tissues presumed to be the source of sepsis (grade 1B).
� Antimicrobial regimen should be reassessed daily for potential deescalation
(grade 1B).
� Use of low procalcitonin levels or similar biomarkers to assist the clinician in the
discontinuation of empiric antibiotics in patients who initially appeared septic, but
have no subsequent evidence of infection (grade 2C).
Fluid Therapy of Severe Sepsis
Crystalloids such as normal saline as the initial fluid of choice in the resuscitation of severe sepsis and septic shock (grade 1B).
� Initial fluid challenge in patients with sepsis-induced tissue hypoperfusion with suspicion of hypovolemia to achieve a minimum of 30 mL/kg of crystalloids (a portion of this may be albumin equivalent). More rapid administration and greater amounts of fluid may be needed in some patients (grade 1C).
�Albumin in the fluid resuscitation of severe sepsis and septic shock when patients require substantial amounts of crystalloids (grade 2C).
�Fluid challenge technique be applied wherein fluid administration is continued as long as there is hemodynamic improvement either based on dynamic (eg, change in pulse pressure, stroke volume variation) or static (eg, arterial pressure, heart rate) variables (UG).
Loss of perfusion is a common feature of sepsis. This patient has altered perfusion of his hand
Vasopressors in Severe Sepsis(only after adequate fluid has been given)
� Vasopressor therapy initially to target a mean arterial pressure
(MAP) of 65 mm Hg (grade 1C).
� Norepinephrine as the first choice vasopressor (grade 1B).
� Epinephrine when an additional agent is needed to maintain
adequate blood pressure (grade 2B).
� Vasopressin 0.03 units/minute can be added to
norepinephrine (NE) with intent of either raising MAP or
decreasing NE dosage (UG).
� Dopamine only in patients with low risk of tachyarrhythmias
and absolute or relative bradycardia) (grade 2C).
� Phenylephrine is not recommended in the treatment of septic
shock except in circumstances where (a) norepinephrine is
associated with serious arrhythmias,
� All patients requiring vasopressors have an arterial catheter placed
as soon as practical if resources are available (UG).
Vasopressors are powerful agents. Side effects include loss of perfusion to periphery
24
Corticosteroids in Severe Sepsis
� Intravenous hydrocortisone only if adequate fluid resuscitation and vasopressor
therapy are unable to restore hemodynamic stability
� suggest intravenous hydrocortisone alone at a dose of 200 mg per day (grade 2C).
� In treated patients hydrocortisone tapered when vasopressors are no longer
required (grade 2D).
� When hydrocortisone is given, use continuous flow (grade 2D).
Setting Goals
� Discuss goals of care and prognosis with
patients and families (grade 1B).
� Sepsis has a high mortality rate.
Families should understand and
recognize that determining what the
patient’s wishes are may help dictate
the aggressiveness of therapy
� Incorporate goals of care into treatment and
end-of-life care planning, utilizing palliative
care principles where appropriate (grade
1B).
� Address goals of care as early as feasible, but
no later than within 72 hours of ICU
admission (grade 2C).
Summary
� Prevent Infections
� Early treatment
� Identify agent
� Remove source
� Antibiotics
� Fluids
� Pressors
� Steroids
� Set goals for end of life

Summary
� Recognize sepsis early
� All infections should be examined for signs of SIRS
� IF sepsis is present
� Obtain blood or site cultures
� Obtain lactate
� Initiate antibiotics
� If organ failure is present, or increased lactate – give 30 ml/kg of
fluids
� If these measures are done in a timely basis, sepsis mortality can
be reduced 50%
