Outline What is sepsis? A brief history of sepsis care How should we take care of septic patients now? Core measures What strategies work? Advice for small hospitals
Sepsis IS Sepsis is NOT The inflammatory response to infection Bacteria in the Blood
Sepsis is a major clinical problem DISEASE NUMBER OF DEATHS/YEAR Severe Sepsis (Angus, 2001) 215,000 AMI (Minino, 2002) 193,000 Lung Cancer (Minino, 2002) 156,000 Colon Cancer (Minino, 2002) 57,000 Breast Cancer (Minino, 2002) 42,000 Minino AM, Arias E, Kochanek KD, et al. Deaths: final data for 2000. National Vital Statistics Reports Web Site.
A patient presenting with severe sepsis has a mortality risk 6-10 times greater than AMI 4-5 times greater than stroke
Diagnosis Terms to foster common dialogue
Diagnosis Sepsis = Systemic Inflammatory Response Syndrome (SIRS) plus suspected infection Sepsis hypotension
First some definitions (you can t treat what you don t recognize) What is SIRS? Systemic inflammatory response syndrome What is sepsis? Severity of sepsis? (and why it matters) Sepsis Severe sepsis Septic shock SIRS criteria (need 2 out of 4) Temp >38.3C or < 36C HR > 90 bpm RR >20/min or pco 2 <32 mmhg WBC < 4000, >12000, or >10% bands SIRS and a SUSPECTED infection 20-35% mortality 30-70% mortality SEPSIS is a MEDICAL EMERGENCY
More definitions What is severe sepsis? Severe sepsis = sepsis + any end organ damage (mortality 20-35%) Evidence of sepsis-induced tissue hypoperfusion or organ dysfunction: Hypotension Elevated lactate > 4 Urine output <0.5ml/kg for >2hr Acute hypoxemia (P:F ratio < 300) Altered mental status Cr >2 mg/dl Bilirubin >2mg/dL Platelet <100, INR >1.5 Paralytic ileus What is septic shock? Septic shock = severe sepsis + need for vasopressors despite fluid resuscitation (mortality 30-70%)
Progressive Mortality can be reversed SIRS

How did we do it? Randomized trial of usual care v. early goal directed therapy 263 patients 16% Absolute risk reduction in mortality
Goal Directed therapy 1. Recognize sepsis (give fluid bolus) 2. Administer fluids to goal CVP 3. Give vasopressors to target MAP 4. Check ScVO2 and treat accordingly 1. low with normal Hgb, give dobutamine 2. low with low hgb, give blood
Early therapy reduces mortality ARR: 46.5 30.5 = 16%. Therefore NNT: 1/ARR or 1/0.16 = 6.25
Comparisons in EGDT vs. Controls
Implementation and effectiveness analysis Hospital costs decrease 22.9% $2,749 - $7019 per QALY
Survivorship has substantially increased
But now I m told goal-directed therapy is dead
ProCESS Trial Objectives Study EGDT in multi-center format Compare 3 protocols Wild-type resuscitation Protocol guided standard care Protocol guided EGDT

What is important All of these patients received fluids equivalent to Rivers et al EGDT 97%+ antibiotics within 6 hours >70% received antibiotics prior to enrollment All identified as sepsis
Editorial
What should we do now? Our best recommendations are those of the core measures However, everything starts with EARLY recognition and a sense of medical emergency
Identifying those at risk and making early diagnosis
Be suspicious.. The key trait for making early diagnosis is having a constantly elevated index of suspicion Physicians need to look for sepsis in the same way they look for stroke or AMI, in fact, it is probably more important
Some thoughts on early diagnosis
A role for lactate? ED at Beth Israel Hospital in Boston 1287 patients with lactates drawn
Lactate up = higher mortality
More on Lactate
Blood pressure changes?
Isolated low BP? 4700 consecutive ED admissions screened for any episode of low BP 887 cases found
Episodes of hypotension
Core Measures In development since before 2007 Extremely complicated measures specifications manual = 63 pages long! labelled as SEP-1
Strategies Create a culture of passion for the care of septic patients Become an evangelist! Take every moment to coach up the team Sepsis care is a TEAM effort Teach away medical mythology create pathways and order sets that leverage current practices in other areas into best sepsis care
Common Myths 1. Avoiding Fluids in certain patient populations 1. Renal failure 2. Heart failure 2. Giving Normal Saline because the potassium is high 3. There is a maximum vasopressor dose 4. We give fluids to raise the blood pressure
Myth #1 I am commonly told that people didn t want to give too much fluid due to either heart failure or renal failure The 30cc/kg bolus septic patients need is well tolerated by almost everyone. Avoiding sufficient fluids is practicing as per the control group in Dr. Rivers goal-directed trial Sepsis associated renal failure is much harder to reverse if we fail to restore perfusion
Myth #2 It is common to avoid Lactated Ringer s if there is acute kidney injury or elevated potassium due to potassium content There is only 4mEq/L of potassium LR is a neutral ph buffered solution vs. NS that has a ph of 4.5 and causes a hyperchloremic acidosis Most hyperkalemia is due to acidosis related cellular shifts. correcting the acidosis fixes the hyperkalemia.
Myth #3 The patient is on max norepi There is simply no such thing. They need what they need. I have used doses as high as 4mkg/kg/min (>400mkg/min) in patients who survive.
Myth # 4 Fluids are given to raise the blood pressure Fact: fluids fill the ventricles and improve stroke volume/cardiac output. If cardiac output doesn t increase with fluid, the patient will NOT benefit from more fluid. Use vasopressors.
Straight leg raise
Antibiotics
Retrospective data collection at 22 centers All patients with sepsis Evaluated appropriate abx by whether it fit guidelines or covered eventual cultures
Outcomes
Summary Sepsis is a MEDICAL EMERGENCY Sepsis care has evolved substantially over 15 years with significantly reduced mortality The core of sepsis care is: Early diagnosis Early fluids Early antibiotics The new core measures reflect these data
