Delayed antimicrobial therapy increases mortality and organ dysfunction duration in pediatric sepsis

Area of Science:

• Pediatric Critical Care Medicine
• Infectious Diseases
• Clinical Pharmacology

Background:

• Delayed antimicrobial administration is linked to adverse outcomes in adult sepsis.
• Limited data exist on the impact of antimicrobial timing on pediatric sepsis outcomes.
• Severe sepsis and septic shock in children require timely and effective interventions.

Purpose of the Study:

• To investigate the association between antimicrobial administration timing and mortality in pediatric severe sepsis or septic shock.
• To determine the effect of delayed antimicrobials on organ dysfunction in pediatric sepsis patients.
• To identify critical time thresholds for antimicrobial delivery in pediatric sepsis.

Main Methods:

• Retrospective observational study design.
• Analysis of 130 pediatric patients with severe sepsis or septic shock.
• Assessment of hourly delays from sepsis recognition to initial and appropriate antimicrobial administration.

Main Results:

• A median delay of 140 minutes to initial and 177 minutes to appropriate antimicrobials was observed.
• Delays exceeding 3 hours were significantly associated with increased pediatric intensive care unit (PICU) mortality.
• More than 3-hour delays correlated with higher mortality odds (OR 3.59-4.92) and fewer organ failure-free days.

Conclusions:

• Delayed antimicrobial therapy is an independent risk factor for mortality in pediatric sepsis.
• Prolonged organ dysfunction is associated with delayed antimicrobial administration in children.
• Prompt initiation of antimicrobials is crucial for improving outcomes in pediatric severe sepsis and septic shock.
