Sepsis Management National Clinical Guideline

• The aim of the guideline is to facilitate the early recognition and appropriate treatment of sepsis in Ireland in order to maximise survival and minimise the burden of chronic sequelae.

• All information regarding the guideline is available on Q-Pulse

• The summary document is available at: www.health.gov.ie/patient-safety/ncec www.hse.ie/sepsis

• The guideline adapts the Surviving Sepsis Campaign guidelines 2013 and Sepsis Six to the Irish context.

Sepsis Management National Clinical Guideline

“Sepsis is a life threatening condition that arises when the body’s response to an infection injures its own tissues and organs. Sepsis leads to shock, multiple organ failure and death especially if not recognised early and treated promptly. Sepsis remains the primary cause of death from infection despite advances in modern medicine, including vaccines, antibiotics and acute care. Millions of people die of sepsis every year worldwide.” Merinoff Symposium 2010: Sepsis

• Approximately 300 cases per 100,000 population per annum. As comparators, myocardial infarction affects 208 and stroke 223 patients per 100,000 per year.

• Mortality from sepsis is currently as high as mortality from acute myocardial infarction was in the 1960s.

• In the U.K. sepsis is estimated to claim 37,000 lives annually and cost the NHS approximately £2.5 billion.

• Sepsis incidence is predicted to grow at a rate of 1.5% annually due to: - aging population - increased numbers of invasive procedures - increasing number of people living with co-morbidities - increasing number of people long-term immunosuppressive therapies.

International context

Irish Context

• Up to 60% of all hospital deaths have a sepsis or infection diagnosis

(HIPE data)• Irish Intensive Care Units Mortality rates of patients with a diagnosis of sepsis is 28.8%

• Mortality rates reduced by 17.7% and average length of stay is decreasing every year with increased awareness.

(National Clinical Effectiveness Committee, 2014; Dellinger et al 2013)

• Each hour of delay in antimicrobial administration associated with an average decrease in survival of 7.6% (Kumar et al, 2006)

UK report from the Health Service Ombudsman

• Lack of timely history and examination on presentation• Lack of necessary investigations• Failure to recognise the severity of the illness• Inadequate first-line treatment with fluids and antibiotics• Delay in administering first-line treatment• Inadequate physiological monitoring of vital signs• Delay in source control of infection• Delay in senior medical input• Lack of timely referral to critical care

DEFINITIONS IMPORTANT TO KNOW

Infection is defined as a pathological process caused by invasion of normally sterile tissue or fluid or body cavity by pathogenic or potentially pathogenic micro-organisms. Sepsis is the clinical syndrome defined by the presence of both infection and the systemic inflammatory response syndrome (SIRS).

Severe sepsis refers to sepsis complicated by organ dysfunction.

Septic shock is defined as severe sepsis with circulatory shock with signs of organ dysfunction or hypoperfusion.

Australian Modification of ICD-10 incorporating the Australian Classification of Health Interventions and the Australian Coding

• Pathogenic features of the microorganism• Patient’s immune response to these features• Failure of the immune system to control an initially localised infection• Exaggerated immune and inflammatory response• Cellular dysfunction• Vasodilation and leaky capillaries

PATHOPHYSIOLOGY OF SEPSIS

• Distributive shock• Myocardial depression• Bone marrow suppression• Activation of clotting cascade DIC (Disseminatedd Intrtavascular Caogulation)

• Organ dysfunction• MODS (Multiple Organ Dysfunction Syndrome)

• Death

Caution:Some groups of patients, such a older people, may not meet the modified SIRS criteria, even though infection is suspected. Where this occurs check for signs of organ dysfunction and raised biomarkers such as CRP.

Sepsis Management National Clinical GuidelineWhat is Sepsis 6?

Why within 1 hour?Each hour of delay in antimicrobial administration decrease in survival of 7.6%.

TAKE 3 GIVE 3

1. CULTURES: Take blood cultures before giving antimicrobials (if no significant delay i.e. >45minutes) and consider source control.

2. BLOODS: Check lactate and full blood count.

3. URINE OUTPUT: Assess urine output and consider urinary catheterisation for accurate measurement in patients with severe sepsis/septic shock.

. OXYGEN: Titrate O2 supplementation to saturations of 94 -98% or 88-92% in chronic lung disease.

2. FLUIDS: Start IV fluid resuscitation if evidence of hypovolaemia and/or shock. 500ml–1000mls bolus of isotonic crystalloid over 15–30 minutes and give up to 30ml/kg, reassessing after each bolus for signs of hypovolaemia, euvolaemia, or fluid overload.

3. ANTIMICROBIALS: Give IV antimicrobials according to local antimicrobial guidelines.

Diagnostic criteria for sepsisGeneral variables• Fever (> 38.3°C)• Hypothermia (core temperature < 36°C)• Heart rate > 90/min–1 or more than two SD above the

normal value for age• Tachypnoea• Altered mental status• Significant oedema or positive fluid balance (> 20 mL/kg

over 24 hr)• Hyperglycemia (plasma glucose > 7.7 mmol/L) in the

absence of diabetes

Inflammatory variables• Leucocytosis (WBC count > 12,000 μL–1)• Leucopenia (WBC count < 4000 μL–1)• Normal WBC count with greater than 10% immature

forms Plasma C-reactive protein more than two SD above the normal value

Haemodynamic variables• Arterial hypotension (SBP < 90mm Hg, MAP < 70

mmHg, or an SBP decrease > 40 mmHg in adults or less than two SD below normal for age)

Organ dysfunction variables• Arterial hypoxaemia (PaO2/FiO2 < 300)• Acute oliguria (urine output < 0.5 mL/kg/hr for at

least 2 hrs despite adequate fluid resuscitation)• Creatinine increase > 0.5mg/dL or 44.2 μmol/L• Coagulation abnormalities (INR > 1.5 or aPTT > 60s)• Ileus (absent bowel sounds)• Thrombocytopenia (platelet count < 100,000 μL–1)• Hyperbilirubinaemia (plasma total bilirubin > 4mg/dL

or 70 μmol/L)

Tissue perfusion variables• Hyperlactatemia (> 1 mmol/L)• Decreased capillary refill or mottling • WCC

20

Severe sepsis

Severe sepsis is defined as sepsis-induced tissue hypoperfusion or organ dysfunction (any of the following thought to be due to the infection)

– Lactate above upper limits laboratory normal– Urine output < 0.5 ml/kg/hr for more than 2 hrs despite adequate fluid resuscitation– Acute lung injury with PaO2/FiO2 < 250 in the absence of pneumonia as infection source– Acute lung injury with PaO2/FiO2 < 300 in the presence of pneumonia as infection source– Creatinine > 176.8 micromol/l– Bilirubin > 34.2 micromol/l– Platelet count < 100,000 μL–1– Coagulopathy (INR > 1.5)– Sepsis induced hypotension.

21

Septic shockSeptic shock is defined as sepsis-induced tissue hypoperfusion persisting after resuscitation with 30mls/kg intravenous isotonic crystalloid fluid as evidenced by:

– Systolic blood pressure < 90 mmHg or MAP < 65 mmHg– Decrease in systolic blood pressure by 40mmHg from baseline and/or– Lactate > 4 mmol/l.

22

Recommendations • Fluid resuscitation with crystalloid • Only consider albumin in patients who continue to require substantial amounts of

crystalloid to maintain adequate MAP.• Avoid hetastarch i.e. gelofusine

• Avoid IV hydrocortisone in adult septic shock patients if adequate fluid resuscitation and vasopressor therapy restore haemodynamic stability

• First choice vasopressor – norepinephrine + additional epinephrine/vasopressin if required. Vasopressin should not be used as initial vasopressor, use for salvage only.

• Dopamine not recommended

• Protocol for glucose management commencing insulin dosing when 2 consecutive BGL levels >10mmol. Keep BGL < 10. Check BGL 1- 2 hrly until stable and then 4 hrly.

• Early imaging to diagnose source of infection. (Dellinger et al 2013)
