Overview • Differentiation between Septic Shock in relation to other conditions in current code, Sepsis, and Severe Sepsis • Disease Epidemiology, Incidence and Mortality • Inadequacy of Current Diagnostic Codes • Proposed Modifications and Clarification • Discussion 2
KEY POINTS • Severe sepsis and septic shock have high prevalence and mortality. • Treatment is time-sensitive and depends on early identification and risk-stratification. • Treatment must include antibiotics and targeted therapies designed to optimize oxygen delivery. • Adherence to a treatment algorithm decreases mortality 3

Systemic Inflammatory Response • At least 2 of 4 ( abnormal temp or leukocytes count is a must) —Core temp >38. 5 or <36 —Tachycardia: HR >2 sd above Normal for age or bradycardia <10% for age —Tachypnea: RR >2 sd for age or mechanical ventilation for acute process —Leukocyte elevated or depressed for age or >10% immature neutrophils 5
Definitions • Infection: Suspected or proven caused by any pathogen Or clinical syndrome associated with high probability of infection • Sepsis: SIRS in the presence of or as a result of suspected of proven infection 6
Definitions • Sepsis is defined as the presence (probable or documented) of infection together with systemic manifestations of infection. • Severe sepsis is defined as sepsis plus sepsisinduced organ dysfunction or tissue hypoperfusion 7
Definitions • Severe Sepsis: sepsis + one —Cardiovascular dysfunction —ARDS —OR 2 or more other organ dysfunctions • Septic shock —Sepsis and cardiovascular organ dysfunction 8
Definitions • Septic shock —Sepsis and cardiovascular organ dysfunction • Septic shock is defined as sepsis-induced hypotension persisting despite adequate fluid • resuscitation. • Sepsis-induced tissue hypoperfusion is defined • as infection-induced hypotension, elevated lactate, or oliguria 9

Conclusion • Septic shock has distinct characteristics that support the creation of a unique code (785. 52) • Septic shock should be linked to severe sepsis • Modification of current SIRS coding will better represent the clinical presentation of the sepsis syndrome — 995. 51, sepsis — Modification to “code also” list in 995. 92 39
Deficiencies of 1991 Consensus Conference • Limitations inherent in these definitions: —Incomplete agreement as to what defines “Systemic Response" § Inflammation only? —Organ/System failures not defined § Except hypotension (SBP <90 mm. Hg or >40 mm. Hg decline from baseline; need for vasopressor support) "Dear SIRS, I do not like you" Jean Louis Vincent
2001 Sepsis Definitions Conference • Current definitions will remain unchanged • However, will accept the uncertainty of definitions • SIRS expanded to signs and symptoms — Chills — Alteration in temperature — Tachypnea — Change in mental status — Tachycardia — Altered WBC, Bandemia — Thrombocytopenia — Decreased perfusion: mottling, poor capillary refill — Increased blood sugar — Petichiae/Purpura 41

Pathophysiology of Sepsis
Pathophysiology of Sepsis Disorder Due to Uncontrolled Inflammation? • Increased inflamatory mediators like IL-1, TNF, IL-6. • Based on animal studies. • In a study in children with meningococcemia, TNF levels directly correlated with mortality. • Clinical trials involving TNF anagonist, antiendotoxin antibodies, IL-1 receptor antagonists, cortocosteroids failed to show any benefits. • Patients with RA treated with TNF antagonist develop infectious complications.
Pathogenesis of Sepsis
Pathophysiology of Sepsis Failure of Immune System to Eliminate Microorganism? • Shift from inflammatory (Th. I) to antiinflammatory response (Th 2). • Anergy. • Apotosis of B cells, T cells, Dendritic cells. • Loss of macrophage expression of MHC Class I and co-stimulatory molecules. • Immunosuppressive effect of apoptotic cells.

Serum Lactate • Hyperlactatemia is typically present in patients with severe sepsis or septic shock and may be secondary to anaerobic metabolism due to hypoperfusion. • The prognostic value of raised blood lactate levels has been well established in septic shock patients, particularly if the high levels persist (that’s why we trend them). • Obtaining serum lactate is essential to identifying tissue hypoperfusion in patients who are not yet hypotensive but who are at risk for septic shock. Information taken from Institute for Healthcare Improvement, Sepsis Module: http: //www. ihi. org/IHI/Topics/Critical. Care/Sepsis/
Blood cultures • The incidence of sepsis and bacteremia in critically ill patients has been increasing in the past two decades. — 30 - 50% of patients presenting with a clinical syndrome of severe sepsis or shock have positive blood cultures. — Therefore, blood should be obtained for culture in any critically ill septic patient. • Collecting blood cultures prior to antibiotic administration offers the best hope of identifying the organism that caused severe sepsis in an individual patient. — Failure to check blood cultures prior to antibiotic infusion will perhaps affect the growth of any blood borne bacteria and prevent a culture from becoming positive later. Information taken from Institute for Healthcare Improvement, Sepsis Module: http: //www. ihi. org/IHI/Topics/Critical. Care/Sepsis/
Broad Spectrum Antibiotics • The balance of evidence unwaveringly suggests that early administration of appropriate antibiotics reduces mortality in patients with Gram-positive and Gram-negative bacteremias. — Some of the evidence supporting early administration is based upon the assumption that patients who fail to receive appropriate antibiotics essentially represent a set of patients for whom delay has occurred in antibiotic delivery. — Several studies have confirmed the mortality benefit associated with appropriate antimicrobials in patients with severe infections due to Gramnegative and Gram-positive bacteria. — All patients should receive a full loading dose of each antimicrobial. § However, patients with sepsis or septic shock often have abnormal renal or hepatic function and may have abnormal volumes of distribution due to aggressive fluid resuscitation. The ICU pharmacist should be consulted to ensure that serum concentrations are attained that maximize efficacy and minimize toxicity Information taken from Institute for Healthcare Improvement, Sepsis Module: http: //www. ihi. org/IHI/Topics/Critical. Care/Sepsis/
Antibiotics and Mortality p = 0. 006 p = 0. 01 • In addition, the major sources of infection in severe sepsis or shock are pneumonia and intraabdominal infections and other sources generally account for < 5 percent of cases. — The prevalence of pneumonia as a cause of sepsis lends support to the case for treating severe sepsis with early antibiotic administration. — In a recent study of ventilator acquired pneumonia, patients with significant organ dysfunction who received antibiotics later had far greater ICU mortality: 37 percent vs. 7 percent, P=0. 006; hospital mortality: 44 percent vs. 15 percent, P=0. 01. Information taken from Institute for Healthcare Improvement, Sepsis Module: http: //www. ihi. org/IHI/Topics/Critical. Care/Sepsis/
Choice of Antibiotics If pseudomonas is an unlikely pathogen, combine vancomycin with one of the following: • Cephalosporin, 3 rd or 4 th generation (e. g. , ceftriaxone, cefotaxime, or cefepime). • Beta-lactam/beta-lactamase inhibitor (e. g. , ampicillin-sulbactam). • Fluroquinolones (eg. , Levofloxacin, gatifloxacin, moxifloxacin. ) If pseudomonas is suspected, combine vancomycin with two of the following : • Antipseudomonal cephalosporin (e. g. , cefepime, ceftazidime, or cefoperazone). • Antipseudomonal carbapenem (eg, imipenem, meropenem). • Antipseudomonal beta-lactam/beta-lactamase inhibitor (e. g. , pipercillintazobactam, ticarcillin-clavulanate). • Aminoglycoside (e. g. , gentamicin, amikacin, tobramycin). • Fluoroquinolone with good anti-pseudomonal activity (e. g. , ciprofloxacin). • Monobactam (e. g. , aztreonam).
Fluid Resuscitation • The Severe Sepsis Resuscitation Bundle calls for an initial administration of 20 – 30 ml/kg of crystalloid as a fluid challenge in cases of suspected hypovolemia or actual cases of serum lactate greater than 4 mmol/L (36 g/dl). — A colloid equivalent is an acceptable alternative to crystalloid, and an equivalent dose generally ranges from 0. 2 g/kg to 0. 3 g/kg depending upon the colloid. • Fluid resuscitation should be commenced as early as possible in the course of septic shock (even before intensive care unit admission). Requirements for fluid infusion are not easily determined so that repeated fluid challenges should be performed. • The bundle does not restrict the amount and extent of an initial fluid challenge, but rather defines a minimum challenge. Subsequent actions in the bundle are undertaken only for hypotension not responding to fluid challenge or for an elevated lactate level as above. Information taken from Institute for Healthcare Improvement, Sepsis Module: http: //www. ihi. org/IHI/Topics/Critical. Care/Sepsis/
Vasopressor Support • Adequate fluid resuscitation is a prerequisite for the successful and appropriate use of vasopressors in patients with septic shock. — In general, the end points of fluid resuscitation are the same as those for the use of pharmacologic hemodynamic support, i. e. MAP > 65 mm. Hg. Sometimes, fluid resuscitation alone may suffice. — When an appropriate fluid challenge fails to restore an adequate arterial pressure and organ perfusion, therapy with vasopressor agents should be started. Vasopressor therapy may also be required transiently to sustain life and maintain perfusion in the face of life-threatening hypotension, even when hypovolemia has not been resolved or when a fluid challenge is in progress • Either norepinephrine or dopamine (through a central catheter as soon as placement is possible) is the first-choice vasopressor agent to correct hypotension in septic shock. Information taken from Institute for Healthcare Improvement, Sepsis Module: http: //www. ihi. org/IHI/Topics/Critical. Care/Sepsis/
Maintaining Hemodynamics • Goal-directed therapy represents an attempt to predefine resuscitation end-points to help clinicians at the bedside to resuscitate patients in septic shock. — The end-points used vary according to the clinical study but attempt to adjust cardiac preload, contractility, and afterload to balance systemic oxygen delivery with demand. • Two essential features of early goal directed therapy include: — maintaining an adequate central venous pressure (CVP) to carryout other hemodynamic adjustments — maximizing mixed or central venous oxygen saturation (Sc. VO 2) • Special patients: — In mechanically ventilated patients, a higher target central venous pressure of 12– 15 mm. Hg is recommended to account for the presence of positive end expiratory pressure and increases in intrathoracic pressure. — Similar consideration to the above may be warranted in circumstances of increased abdominal pressure. Information taken from Institute for Healthcare Improvement, Sepsis Module: http: //www. ihi. org/IHI/Topics/Critical. Care/Sepsis/
Blood products • When it’s used: if the Sc. VO 2 remains < 70% despite adequate fluid resuscitation, consider transfusion to a hematocrit of 30%. • How it works: Increases blood carrying capacity to the tissues. • Dosing: — Patient specific (however, 1 unit of PRBCs should increase the hematocrit by ~3%) • Monitoring: — Per routine
