Infections in the ICU • Sepsis and multiple organ failure is the

commonest cause of death in ICU’s • ICU patients are 5-10 times more prone

to infection • Increased nosocomial infections • Infections with resistant strains

ICU

Community Hospital

• Widespread use of oral QN and Ceph

• Free availability of OTC antibiotics

• Self-medication by patients

• Availability of cheap generics of variable potency and quality

• Spread by crowding and poor sanitary conditions.

• Lack of hospital-wide infection control or antibiotic policies

• Extensive empirical use of cephalosporins in hospitals and ICUs

• Prolonged use of antimicrobial prophylaxis in surgical patients

• Failure to restrict privileges to prescribe major antibiotics

Absence of national agency to survey and report on nosocomial inffections Absence of effective national or statewide antimicrobial policy

• Predominance of open ICUs • Failure to implement or adhere to

infection control protocols • Prolonged use of broad-spectrum

antibiotics • Inadequate staffing, especially

nurses

Management of Severe Sepsis

• Antibiotics for primary infection • Percutaneous or surgical drainage • High-quality intensive care • Modulate inflammatory response • Prevent secondary infections

– Exogenous & endogenous

Antibiotic Therapy in Sepsis • Start early, after obtaining samples for C/S • Intravenous • Adequate doses • Broad-spectrum • Initially empirical • Specific therapy after C/S • De-escalate whenever possible

Consequences of Overdiagnosis of Sepsis

• Inappropriate use of antibiotics • Increases costs • Risk of adverse drug reactions • Selects for resistant microbial flora

– increase morbidity and mortality • Incorrect diagnosis can engender a false

sense of security – Distract a clinician from finding and treating

the true cause of a patient’s clinical deterioration

JAMA 2007; 297:1583-93

Broad-Spectrum Antibiotics Creating problems

• Kill harmful organisms, and several other non-pathogenic ones as well

• Negative culture reports • Overgrowth of Cl. difficile • Overgrowth of fungi • Selects out resistant organisms • Induces resistance

Antimicrobial Stewardship Strategies

• Education • Clinical guidelines • Antimicrobial restriction • Preprescription approval • Prospective audit and feedback

– Postprescription review • Computer-based decision support • Antibiotic cycling?

Optimising antimicrobial therapy

• Avoid prolonged Prophylactic Antibiotics • Combination therapy • Dose and route • PK / PD principles • De-escalation • Duration of therapy • Biomarker guided therapy : procalcitonin • Patenteral to oral conversion

Barriers to De-escalation • Negative blood / other cultures.

– 40-60% of blood cultures may be negative • Positive cultures : colonization or infection?

– Contaminants – Errors in collection of samples – Quantitative instead of Non quantitative cultures

• No clinical improvement • Clincal improvement

• Why change a winning team?

• Role of biomarkers • Advanced molecular diagnostic

techniques

Bundles of Care • Concept of “bundles” developed by IHI

• Help health care providers more reliably deliver the best possible care for patients undergoing particular treatments with inherent risks

• Structured way of improving the processes of care and patient outcomes

• A small, straightforward set of evidence-based practices — generally three to five — that, when performed collectively and reliably, have been proven to improve patient outcomes

Sepsis Resuscitation Bundle Goals in the first 6 hours

1. Serum lactate measured 2. Blood cultures obtained prior to antibiotics 3. From the time of presentation, broad-spectrum antibiotics administered

within 1 hour In the event of hypotension and/or lactate >4 mmol/L 4. Deliver an initial minimum of 20 ml/kg of crystalloid (or colloid

equivalent*) 5. Vasopressors for hypotension not responding to initial fluid

resuscitation to maintain MAP ≥65 mm Hg 6. Achieve CVP of 8 mm Hg 7. Achieve ScvO2 of ≥ 70%

Sepsis Management Bundle Goals over 24 hours

• Low-dose steroids administered for refractory septic shock not responding to fluids and vasopressor therapy

• Glucose control maintained ≥ lower limit of normal, but < 180 mg/dl

• Inspiratory plateau pressures maintained < 30 cm H2O for mechanically ventilated patients

study • 1285 patients recruited, 16 countries, 148 ICUs

• All consecutive patients with severe sepsis in July 2009 • Excluded patients

– < 21yrs – Transferred from another hospital or from another ICU – Previously admitted to the ICU for severe sepsis

• Primary Outcome – Compliance with the 6-hour and 24-hour bundles

• Secondary Outcome – All-cause in-hospital mortality

• Hand Hygeine • Care to prevent Nosocomial Pneumonia • Vascular Catheter Care • Urinary Catheter Care

Care to Prevent Nosocomial Pneumonia

• Elevation of the Head of the Bed (30-45

degrees)

• Tubings / Water traps free of fluid and

secretions

• Absent air leak around cuff

• Smooth enteric nutrition

• Aseptic Aspiration technique

Care to prevent CLABSI

• Date of Catheter Insertion • Correct condition of dressing • Sterile Dressings for peripheral lines • Use needleless intravascular catheter

access systems avoid stopcocks. • Closed catheter access systems should be

preferred to open systems.

Process Surveillance Forms – Vascular Catheter Care

• Correct condition of dressing - well coated - clean - no fluid collection • Date of Catheter Insertion

Process Surveillance Forms – Urinary Catheter Care

• Catheter over thigh • Level of the urine bag below level of the bladder • Urine bag should not have floor contact
