Clinician response time for positive blood culture results in a pediatric ICU

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Pediatric Hospital Medicine

Background:

• Positive blood cultures are crucial for guiding antimicrobial therapy based on in vitro susceptibility.
• Delays in initiating appropriate antibiotic treatment following positive blood cultures are linked to increased patient morbidity.

Purpose of the Study:

• To evaluate the time interval between clinician notification of a positive blood culture and the administration of targeted antimicrobial therapy.
• To assess adherence to Surviving Sepsis guidelines regarding timely antimicrobial administration.

Main Methods:

• Retrospective chart review of pediatric intensive care unit (PICU) patients with positive blood cultures.
• Data extraction included timing of blood culture collection, clinician notification, and initiation of new antimicrobial therapy.
• Analysis of 174 positive blood cultures from 111 PICU patients.

Main Results:

• Antimicrobial therapy was adjusted post-positive culture in 51% of patients.
• The average time from clinician notification to new antibiotic administration was 6 hours and 35 minutes.
• This indicates a delay in initiating targeted antimicrobial therapy.

Conclusions:

• A notable delay exists between clinician notification of positive blood cultures and the administration of appropriate antimicrobial therapy.
• Optimizing this thời gian interval is critical for improving patient outcomes and reducing morbidity associated with bloodstream infections.
