• Modifying EGDT: Protocolized Care in 2015

• Preventing Readmissions

• Case: Conclusion

“Except on few occasions, the

patient appears to die from the

body’s response to infection rather

than from…[the infection itself….]”

Sir William Osler, 1904

SEP-1: Overview

SEP-1

• Not a talk about implementing SEP-1

• Goal: Efficient, effective, timely care

• Acknowledges “burden of severe sepsis”

• If 2 SIRS, infection, organ dysfxn, then…

• 3 Hour Goals

– Lactate, blood cultures, antibiotics, fluid

• 6 Hour Goals

– Repeat lactate, vasopressors, assessment of

volume status, tissue perfusion

A Case: Initial Presentation

Case Vignette

• 54 year-old male

• PMHx: HTN, PAF, HL, and OA

• Chief complaint: abdominal pain

• Began 3 days ago after eating dinner, stuttering since then, becoming more severe/constant about 6 hours before presentation

• Fever to 101.5°F, 4 hours prior, treated w/ acetaminophen; two days nausea; one episode of vomiting earlier today

Case Vignette

• Allergies: NKDA

• Medications: ASA, metoprolol, amlodipine, simivastatin

• Triage VS: Tº, 100.5°F; BP, 128/78 mm Hg; HR, 88 beats per minute; RR, 21 breaths per minute; and O2 sat, 96% on RA; pain, 6/10

• Triaged as ESI 3 patient, and asked to wait in the waiting room along with 15 other patients waiting to be seen

Our patient. Next steps?

• Patient waits to be seen

• Other easily obtainable data that could help clarify the urgency of initiating treatment?

• What if serum lactate is 1.4 mmol/L?

• What if it is 4.1 mmol/L?

• EMR algorithm utilizes CC + VS to generate an automatic order for a serum lactate

• Drawn by EMT 10 minutes after triage

• Sent to the critical care laboratory for analysis

Challenge of sepsis patients

• This is a typical sepsis patient

• Why sepsis? – Presumed infection (likely intra-abdominal process) +

inflammatory response (fever, tachypnea)

• Challenge for clinicians: – How sick is he?

– Does he have a time-sensitive infection?

– How aggressive does his treatment need to be?

• On initial presentation: – no obvious signs of end organ dysfunction

– Does not obviously have severe sepsis

– What does this mean?

•Lactate > 4

Our Case: Changing Severity

Patient Vignette

• Lactate (15 minutes after sent)= 5.4 mmol/L

• Immediately brought back to a treatment room

• 2 18 gauge IVs placed

• 3 L NSS were infused in 1 hr

• WBC=16.5; HCO3-=18; Tbili=2.7; Alk phos=235; AST/ALT 335/284; lipase 650

Patient Vignette

• Repeat VS: BP 128/82; HR 84; RR 24

• Bedside ultrasound: – Gallstones

– GBWT

– Dilated intrahepatic ducts

• Bedside ECHO: – Under-filled RV

– > 50% IVC collapse

• Continue volume resuscitation

• Close monitoring

Goals of Resuscitation

Initial Management

IV access

Fluid resuscitation

Supplemental oxygen

Cardiac monitoring

Labs, cultures, CXR

Antibiotics

Is the patient in shock?

Goals of Interventions for Shock

• Stabilize patient

• Eradicate source of infection

• Restore perfusion

• Modulate body’s inflammatory and

anti-inflammatory responses

• Cessation of ongoing lactate

production

Epidemiology of Sepsis

Why is this so Important?

• A patient a minute presents to a US ED

• 750,000 cases/yr of severe sepsis in USA

• 215,000 deaths/yr directly related to sepsis

• Tenth leading cause of death in USA

• Rate of sepsis cases is increasing faster than the population

• 37% of severe sepsis patients come through the ED

Wang et al. Crit Care Med, 2007

Angus et al. Crit Care Med, 2001

Underestimate?

• “Benchmarking the incidence and mortality of

severe sepsis in the United States”

• NIS: Nationally representative sample

• 4 previously validated capture techniques

(Angus, Wang, Dobrovskii, Martin)

• All utilize ICD 9 codes (+/- sepsis codes)

• Annual incidence and mortality from severe

sepsis

Early Goal-Directed Therapy

Negative Trials in the 80s and 90s

• High dose methylprednisolone

• NSAIDs

• Anti-LPS

• TNF receptor antagonists

• GOT

• Shared features: – ICU initiated

– 24 hours or more to enrollment

– Non-selective interventions

A new approach was needed…

Critical Care

• Critical care is a concept

not a location

• It is a way of treating patients that

begins in the pre-hospital setting with

EMS care, continues in the ED, and is

completed in the ICU

Mortality in Admitted Patients

SIRS, Severe Sepsis

• Historically, SIRS=>very sensitive; but not

specific

• Shapiro: SIRS neither sensitive nor specific

• 3102 pts, suspected infection (blood culture

drawn) – 34% (420/1219) severe sepsis pts didn’t meet SIRS criteria

– 24% (13/54) septic shock pts didn’t meet SIRS criteria

Shapiro et al, Ann Emerg Med 2006

• 172 ICUs in Australia, New Zealand

• 109,663 severe sepsis patients

– 87.9% SIRS-positive

– 12.1% SIRS-negative

• “The need for two or more SIRS

criteria…excluded one in eight otherwise

similar patients with infection, organ failure,

and substantial mortality…”

Cycle

• Hypothesis

– Lactate measured on ED presentation is associated with mortality and risk stratifies severe sepsis patients INDEPENDENT of blood pressure

• 831/856 (97%) of admitted severe sepsis pts had lactate sent

– Median lactate=2.9 mmol/L

– 28 day mortality: 22.7%

• Divided into:

– Low: ≤ 2mmol/L

– Medium: > 2 to ≤ 3.9mmol/L

– High: ≥ 4mmol/L

• Stratified to presence or absence of refractory hypotension

Patient Vignette (cont’d)

• A-line placed in L femoral artery

• CVC placed in the R IJ vein under ultrasound guidance – initial CVP: 6 mmHg, MAP: 55 mmHg, initial

ScvO2: 38%

• Further fluid boluses

• After 4 L NSS was infused – CVP: 12 mmHg

– MAP: 59 mmHg

– ScvO2: 45%

Patient Vignette (cont’d)

• Input: 4550cc; Output 20cc

• Repeat ECHO: – Decreased contractility, EF 45%

– IVC collapse decreased

• Started on norepinephrine and dobutamine

• Given Vancomycin and Piperacillin-Tazobactam with 1st antibiotic started 50 minutes after triage

Does that matter?

Time to Antibiotics

Time to Antibiotics

• Design – Retrospective cohort study of 14 ICUs

• Patients – 2,731 adults with septic shock

• Primary variable – Duration of hypotension prior to administration

of appropriate antimicrobial

• Primary outcome measure – Survival to hospital discharge

Modifying EGDT

• Protocol-driven sepsis care lowers mortality

• EGDT underutilized

• What factors are associated with not initiating

EGDT in ED?

• 340 EGDT-eligible patients

• EGDT not initiated in 142 pts (42%)

Mikkelsen et al. Chest, 2010

Mikkelsen et al. Chest, 2010

4 Risk Factors Associated with Non-

adherence

• Female patient (p=0.001)

• Female physician (p=0.041)

• Lactate as qualifying criterion (p=0.018)

• Skin infections or urinary tract infections

• Non-consultation of severe sepsis

service (p<0.001)

Mikkelsen et al. Chest, 2010

Protocolized Care

• 2013, protocolized care = standard of care

• Objective interventions/Objective endpoints

• Goal: differentiate Responders from Non-Responders @ each stage of resuscitation

• Potential Organ Dysfunction Immediate attention regardless of patient location in health care system

• EGDT most famous type of protocolized care

• New insights arrive…

The ProCESS Trial

• Three arms:

1.Protocol-based EGDT

2.Protocol-based standard therapy Similar to # 1 but no mandated CVC, transfusion only

for Hgb<7.5, fluids only to “volume repleted”, no specific pressor mandates

3.“Usual care” (clinician’s preference)

ProCESS

• 51 ICUs in Australia and New Zealand

• 1600 patients presenting to the ED in early

septic shock

• 2 SIRS, source of infection, hypotension or

hypoperfusion

• Antibiotics prior to randomization

• Randomized to EGDT vs. usual care

Preventing Readmissions

Post-Discharge Problems

• “Unfortunately, discharge from a severe

sepsis hospitalization is all too often the

beginning of the end”

• Iwashnya and colleagues:

– the 3-year case-fatality rate remains

stubbornly above 70%

– Readmissions common

– Costs are staggering

Buchmann, “You Tell Me.” CCM, 2015

Readmissions @ Penn

• Patients admitted with septic shock (serum

lactate ≥ 4 mmol/L or refractory hypotension)

and discharged alive to a non- hospice

setting between 2007 and 2010

• 269 at-risk survivors:

– 63 (23.4%; 95% CI, 18.2–28.5) were readmitted

within 30 days of discharge

– 12 (4.5%; 95% CI, 2.3–7.7) returned to the ED for

a treat-and-release visit

Ortego et al. CCM, 2015

Readmissions @ Penn

• 75% of readmissions occurred within

15 days of discharge:

– more likely in oncology pts (p = 0.001)

– pts with a longer hospital LOS (p = 0.04)

– 16% resulted in death or d/c to hospice

– Potentially related to the index septic shock

hospitalization in 78% (49/63) of cases

– 46% of readmissions were infection-related

Ortego et al. CCM, 2015

Case Conclusion

• Evaluated by ESS

• Went to IR for a percutaneous drain

• E. coli in blood cultures and drainage fluid

• On NE and DOBUT for 3 days

• Clinically stabilized

• Delayed cholecystectomy

• Discharged in good condition on HD-17

Conclusions-1

• Osler was right—the patient dies as much from the body’s response to infection as from the infection itself

• Huge epidemiologic burden of sepsis

• Recognition: major hurdle

• SIRS: Helpful but not infallible

• Lactate: marker for critical illness and powerful screening tool

Conclusions-2

• Protocolized care improves outcomes

• Modify to fit different resource settings

• Antibiotics: – integrate into early resuscitation strategies

– prioritize along w/ other aspects of initial critical care

• Rivers’ fundamental insight: – moving aggressive, protocolized care to the most

proximate phase of critical illness

• The optimal details remain to be elucidated

• SEP-1 adherence should further improve care
