Six-Hour Sepsis Bundle Decreases Mortality: Truth or Illusion - A Prospective Observational Study

Area of Science:

• Pediatric critical care medicine
• Infectious diseases
• Clinical outcomes research

Background:

• Severe sepsis and septic shock are critical conditions in children.
• The 6-hour sepsis bundle aims to improve outcomes through standardized care.
• Understanding factors influencing mortality in pediatric sepsis is crucial.

Purpose of the Study:

• To evaluate if adherence to the 6-hour sepsis bundle reduces mortality in pediatric severe sepsis and septic shock.
• To assess the relationship between sepsis bundle compliance and patient outcomes.

Main Methods:

• Prospective enrollment of 116 pediatric patients (1 month-13 years) with severe sepsis or septic shock.
• Data collection included sepsis bundle components and blood investigations.
• Mortality prediction using the Pediatric Index of Mortality-2 (PIM-2) score; compliance defined by fulfilling all 6-hour bundle elements.

Main Results:

• 90 patients (77.59%) achieved 100% sepsis bundle compliance; 26 (22.41%) were noncompliant.
• Mortality was higher in the compliant group (44.4%) versus the noncompliant group (19.3%), P = 0.020.
• Higher pre- and post-intervention lactate levels and increasing PIM-2 scores were observed in the compliant group, correlating with mortality.

Conclusions:

• Sepsis bundle compliance alone did not appear to decrease mortality in this pediatric cohort.
• Illness severity, reflected by lactate levels and predicted mortality (PIM-2 score), significantly influences patient outcomes.
• Further research may be needed to refine sepsis management protocols for pediatric severe sepsis and septic shock.
