24 Revision of SSC Bundles Based utilizing analysis of 28,000 patient in the SSC database: in 2012 SSC revised the guidelines New software was to be developed No industry funding utilized in revising guidelines or bundles

25 Multivariable Mortality Prediction Model: Population-averaged Panel Logistic Regression

26 Revised SSC Bundles Management bundle dropped IPP: High compliance at outset of study No significant change in compliance Glucose Clouded by controversy Steroids OR > 1.0 in SSC analysis rhapc PROWESS-SHOCK negative Removed from market

27 Revised SSC Bundles Two resuscitation bundles Analysis of large database confirm importance of early identification and resuscitation Initial resuscitation bundle To be initiated immediately upon identifying patients with severe sepsis and septic shock Septic Shock bundle To be initiated immediately and completed within 6 hours for patients with septic shock Bundles consistent with previous Resuscitation bundle No new metrics

28 SSC Sepsis Resuscitation Bundle 2012 (To be started immediately and completed within 3 hours) 1. Measure serum lactate 2. Obtain blood cultures prior to antibiotic administration 3. Minimize time to administration of broad-spectrum antibiotics with a maximum of 3 hours from ED triage and 1 hours for non-ed patients. 4. In the event of hypotension and/or lactate > 4mmol/L, deliver a minimum of 30 ml/kg of crystalloid (or colloid equivalent).

29 SSC Septic Shock Bundle 2012 (To be started immediately and completed within 6 hours) 5. Apply vasopressors for hypotension that does not respond to initial fluid resuscitation to maintain mean arterial pressure (MAP) > 65 mm Hg. 6. In the event of persistent arterial hypotension despite volume resuscitation (septic shock) and/or initial lactate > 4 mmol/l (36 mg/dl): Achieve central venous pressure (CVP) of > 8 mm Hg. Achieve central venous oxygen saturation (ScvO2) of > 70%.*

30 Severe Sepsis/Septic Shock New Cohort Definition for Intermountain Include adults patient 18 years or older with discharge ICD9 codes (Severe Sepsis), (Septic Shock) or (sepsis) + an organ failure code admitted to ICU from ER or FLOOR (using encounter ICD9 codes)» Organ failure codes» Acute Renal Failure» Acute Renal Failure» Acute Renal Failure» Acute Renal Failure» Acute Renal Failure» Acute Renal Failure» Acute Renal Failure» Acute Renal Failure» Acute Renal Failure» Acute Renal Failure» Acute Respiratory Failure» Myopathy» Critical Illness Polyneuropathy» DIC /Coagulopathy» Metabolic Encephalopathy» 570 Acute liver failure

31 Old Method 2004 From Combined Query (n=11,877) New Method 2013 From IMCP screening table uses a very broad search (n=11,549) From Casemix by ICD 9 (n=5,288) Captured by IMCP table but 6,589 did not match Matched from both queries (n=4,960) Captured by ICD9 codes only 328 did not match 94% Disqualified by RN (n=6,201) 6% Qualified by RN (n=388) Septic shock=68 Severe sepsis=296 Blank=24 Septic shock (785.52) = 58 Severe sepsis (995.92) = 79 Sepsis W AOF = 53 Mild/moderate sepsis = 138 Only 46% patients screened positive by old method were not verified by RN as severe sepsis or septic shock

32 HVHC-CCMI Study Population: A subset of patients of IMCP study population Inclusion criteria: Include adults patient 18 years or older with discharge ICD9 codes (Severe Sepsis), (Septic Shock) admitted to ICU from ER, OR or Floor (using encounter ICD9 codes) Participated hospitals: Intensive Care Units at IMC, LDS, McKay-Dee, Utah Valley and Dixie Exclusion criteria: Patients transferred from other facility are excluded from the study

33 2013 Severe Sepsis Resuscitation Bundle: To be done within a maximum of 3 hours from ED triage or within 1 hour for non-ed patients from the time of ICU admission 1. Measure serum lactate 2. Obtain blood cultures prior to antibiotic administration 3. Minimize time to administration of broad-spectrum antibiotics within a maximum of 3 hours from ED triage or within 1 hour for non-ed patients from the time of diagnosis. 4. In the event of hypotension and/or lactate > 4 mmol/l, start a fluid bolus of 30 ml/kg of crystalloid IV to run over not more than 60 minutes.

34 2013 Septic Shock Bundle: To be done within a max. of 6 hours from ED triage or within 6 hour for non-ed patients from the time of ICU admission 5. Apply vasopressors for hypotension that does not respond to initial fluid resuscitation to maintain mean arterial pressure (MAP) > 65 mm Hg. (Norepinephrine is the preferred vasopressor for initial therapy starting at 0.02 mcg/kg/minute if not contraindicated) Shock defined as hypotension (SBP persistently < 90mmHg on 2 or more readings) or Lactate > 4.0mmol/L that is not responsive to 30 ml/kg PBW crystalloid fluid bolus by returning to and remaining at normal values

35 2013 Septic Shock Bundle: 6. In the event of persistent arterial hypotension (SBP < 90) despite volume resuscitation of 30 ml/kg PBW and/or lactate > 4 mmol/l, begin further volume resuscitation** and vasopressor support as needed to: 6a. Achieve central venous pressure CVP> 8 mm Hg. or if using NICOM protocol, until either patient is no longer fluid responsive (has < 10% increase in stroke volume index following passive leg raise) or patient becomes stable off vasopressors. 6b. Achieve central venous oxygen saturation (ScvO2) of > 70%. or if using NICOM protocol achieve a cardiac index (CI) greater than 2.5 L/minute/M 2 7. If initial lactate is elevated > 2 mmol/l, repeat measurement within 6 hours of time zero.

36 Maintenance Bundle: 8. If on ventilator and on A/C target Vt at 6 ml/kg PBW (range 4-7 ml/kg PBW 9. Achieve and maintain an average glucose between within the last 12 hours of the first 24 hour period using bedside measurements done at least every 4 hour or less intervals.**** 10. If on high dose vasopressors*** give hydrocortisone 200 mg/24 hours in divided doses of 50 mg Q6 hours or as a continuous infusion. NOTE: The telemedicine system will facilitate bundle tracking and performance for non- ED patients.
