Managing Sepsis Bundles

Documents to Request

• Sepsis screening tool timestamp (nursing or EMR alert)
• Initial and repeat lactate values with timestamps
• Blood culture collection time (before antibiotics)
• Antibiotic order time AND administration time (these differ and both matter)
• Fluid resuscitation volume and administration times
• Vasopressor initiation time (if applicable)
• Physician reassessment documentation after fluid bolus
• Source control assessment (imaging, surgical consultation)
• Procalcitonin and other biomarkers if obtained

Step 1: Sepsis-3 Definition Application

Sepsis Identification

Sepsis = Suspected or documented infection + acute organ dysfunction (SOFA score increase ≥2 points from baseline)

qSOFA (Quick SOFA) — Bedside Screening Tool

qSOFA ≥2 suggests possible sepsis and should trigger further workup. Note: qSOFA is a screening tool, not a diagnostic criterion—it has high specificity but low sensitivity.

SOFA Score Components (for organ dysfunction quantification)

Septic shock = Sepsis + vasopressor requirement to maintain MAP ≥65 + lactate >2 mmol/L despite adequate volume resuscitation.

Step 2: SEP-1 Bundle Elements and Timing

Hour-1 Bundle (Surviving Sepsis Campaign 2021)

All elements should be initiated within 1 hour of sepsis recognition:

Antibiotic Selection by Suspected Source

Step 3: Fluid Resuscitation and Hemodynamic Management

Initial Fluid Resuscitation

1. Calculate 30 mL/kg based on actual body weight (NOT ideal body weight)
2. Use balanced crystalloid (lactated Ringer's or Plasmalyte) preferred over 0.9% NaCl to reduce hyperchloremic acidosis
3. Administer as rapidly as tolerated—most should complete within 1-3 hours
4. Document fluid responsiveness: improvement in MAP, heart rate, urine output, lactate

Vasopressor Initiation

If MAP remains <65 mmHg after 30 mL/kg crystalloid (or clinician reassessment determines further fluid is unlikely to benefit):

Step 4: Lactate Clearance Monitoring

Target: ≥10% lactate clearance per 2 hours OR normalization (<2 mmol/L). Failure to clear lactate despite adequate resuscitation suggests ongoing tissue hypoxia, need for source control, or mitochondrial dysfunction.

Step 5: Source Control and Reassessment

1. Identify the source: obtain appropriate imaging (CT abdomen, chest X-ray, ultrasound)
2. Determine if source requires intervention: abscess drainage, surgical debridement, device removal, decompression
3. Source control should be achieved within 6-12 hours of identification when possible
4. Reassess at 6 hours: repeat vital signs, lactate, clinical exam
5. De-escalate antibiotics within 48-72 hours based on culture sensitivities
6. Consider stopping antibiotics at 7-10 days for most infections; use procalcitonin-guided discontinuation when available

Checkpoint B: Post-Draft Alignment (Mandatory)

1. Is the time zero (sepsis recognition time) clearly documented and defensible?
2. Were blood cultures obtained BEFORE the first antibiotic dose (timestamp comparison)?
3. Is the antibiotic regimen appropriate for the suspected source with adequate spectrum?
4. Is fluid resuscitation calculated at 30 mL/kg with actual body weight documented?
5. Is the 6-hour physician reassessment documented with exam findings and plan?

Quality Audit

Guidelines

1. Time zero determination is the most contested element in SEP-1—it should be the earliest time that infection AND organ dysfunction criteria are simultaneously present; retrospective backdating is a compliance and legal risk
2. Blood cultures before antibiotics is critical but should never delay antibiotic administration more than 45 minutes—if access is difficult, give antibiotics and document the reason cultures were deferred
3. 30 mL/kg is not mandatory for every sepsis patient—it applies only to sepsis-induced hypotension or lactate ≥4; for normotensive sepsis without elevated lactate, fluid decisions are clinician judgment
4. Heart failure and ESRD patients may not tolerate 30 mL/kg—document clinical assessment, consider smaller boluses with reassessment, and document the rationale for modified fluid volumes
5. Norepinephrine is first-line vasopressor—dopamine is associated with higher arrhythmia rates and mortality in septic shock; it should not be used as a first-line agent
6. Lactate is not a specific marker—elevated lactate can reflect aerobic glycolysis (beta-agonists, epinephrine), liver failure, or seizure rather than tissue hypoxia; interpret in clinical context
7. Procalcitonin is most useful for guiding antibiotic duration (discontinue when PCT <0.25 or >80% decline from peak) rather than for initial diagnosis
8. Corticosteroids (hydrocortisone 200 mg/day IV) are recommended for septic shock refractory to vasopressors, not for routine sepsis management
