Evidence Based Medicine Grading System

Grades of Recommendation, Assessment, Development and Evaluation (GRADE)

Grading Quality of Evidence A- high quality –Randomized controlled trial (RCT) B- intermediate –Downgraded RCT or upgraded observational C- low –Observational or cohort D- very low –Case series or expert opinion Upgrade capability

Grading Strength of Recommendation 1- strong recommendation – Do it –We recommend 2- weak recommendation – Probably do it –We suggest Determinants of strength –Quality of evidence –Relative importance of outcomes –Risks and costs –Absolute magnitude and precision of effect

Kumar A, et al. Crit Care Med 2006; 34:

Antibiotic Therapy  We recommend beginning intravenous antibiotics within first hour of recognition of severe sepsis 1B

Broad antibiotic coverage initially Narrow coverage after return of cultures Source control as soon as possible and within 6 hours

Initial Resuscitation

Resuscitation of Sepsis Induced Tissue Hypoperfusion Recommend MAP 65 mm Hg Recommend urine output.5 ml/kg/hr Grade 1C

Fluid Therapy Recommend fluid resuscitation may consist of natural or artificial colloids or crystalloids. Grade 1B

The SAFE Study Investigators, N Engl J Med 2004;350:2247 Relative Risk of Death from Any Cause among All the Patients and among the Patients in the Six Predefined Subgroups of Survival

Sepsis Induced Hypotension Fluid challenge –Minimum of 20 ml/kg crystalloid or colloid equivalent

Sepsis Induced Tissue Hypoperfusion  Requirement for Vasopressors after initial fluid challenge  Lactate ≥ 4 mg/dL

De Backer D, et al. N Engl J Med 2010, 362;9: Predefined subgroup analysis by type of shock

Phenylephrine Pure vasoconstrictor in general should be avoided –Decreases cardiac output Rare exceptions –Cardiac output measured and high and difficulty with maintaining MAP with other vasopressor agents –Profound tachycardia or severe ventricular arrhythmias with norepinephrine

Initial Resuscitation of Persistent Hypotension or Lactate >4 Recommend Insertion central venous catheter Recommended goals : Central venous pressure: 8–12 mm Hg Higher with altered ventricular compliance or increased intrathoracic pressure ScvO2 saturation (SVC)  70% Grade 1C

FRENCH TRIALCORTICUS Overall Severity of Illness Duration of Shock < 8 hrs< 72 hrs Degree of Hypotension Potential for Selection BiasUnlikelyYes

Steroids Suggest intravenous hydrocortisone be given only to adult septic shock patients after blood pressure is identified to be poorly responsive to fluid resuscitation and vasopressor therapy Grade 2C

Recombinant Human Activated Protein C (rhAPC) Suggest use in patients with clinical assessment of high risk of death due to sepsis induced organ dysfunction typically with APACHE II 25 or greater or multiple organ failure No absolute contraindications Weigh relative contraindications Grade 2B

As to Guidelines Publications “Knowledge is Good”

Guidelines Are Not Enough Protocols Performance Improvement Programs

Severe Sepsis Resuscitation Bundle Implement the 6-hour bundle. Available at: Complete tasks within 6 hours of identifying severe sepsis. 1.Measure serum lactate. 2.Obtain blood cultures prior to antibiotic administration. 3.Administer broad-spectrum antibiotic within 3 hours of ED admission and within 1 hour of non-ED admission. 4.In the event of hypotension and/or serum lactate > 4 mmol/L: a.Deliver an initial minimum of 20 mL/kg of crystalloid or equivalent. b.Begin vasopressors for hypotension not responding to initial fluid resuscitation to maintain MAP > 65 mm Hg. 5.In the event of persistent hypotension despite fluid resuscitation (septic shock) and/or lactate > 4 mmol/L: a.Achieve a central venous pressure (CVP) of > 8 mm Hg b.Achieve a central venous oxygen saturation (ScvO 2 ) > 70% or mixed venous oxygen saturation (ScvO 2 ) > 65%
