Pediatric sepsis remains a critical issue, but quality improvement collaboratives show promise. The IPSO initiative aims to reduce pediatric sepsis mortality and hospital-onset sepsis through evidence-based interventions and collaborative learning.
Area of Science:
- Pediatrics
- Critical Care Medicine
- Public Health
Background:
- Pediatric sepsis is a significant public health concern with persistent challenges despite existing guidelines.
- Current initiatives have yielded modest improvements, highlighting the need for enhanced strategies.
Purpose of the Study:
- To improve sepsis outcomes in pediatric emergency departments, ICUs, general care, and hematology/oncology units.
- To reduce sepsis-attributable mortality and hospital-onset sepsis incidence by 25% through a collaborative quality improvement initiative.
Main Methods:
- Development of a multicenter quality improvement learning collaborative (Improving Pediatric Sepsis Outcomes - IPSO) involving US children's hospitals.
- Review of treatment guidelines and literature, coupled with expert opinion, to create a key driver diagram (KDD).
- Engagement of 56 hospital-based teams in educational and information-sharing activities.
Main Results:
- Established baseline sepsis-attributable mortality at 3.1% and hospital-onset sepsis incidence at 1.3 cases per 1000 admissions.
- Developed a KDD with primary drivers focused on infection treatment, sepsis recognition/diagnosis, care de-escalation, patient/family engagement, and performance optimization.
- Achieved 100% team engagement in collaborative learning and information sharing.
Conclusions:
- The IPSO collaborative provides a framework for improving pediatric sepsis outcomes.
- Collaborative learning and reliable implementation of evidence-based interventions are key to reducing pediatric sepsis mortality and incidence.
- The KDD serves as a strategic tool to guide quality improvement efforts in pediatric sepsis management.
