Protocol for a multi-country retrospective observational paediatric sepsis epidemiological study (SENTINEL International)

TL;DR

This study aims to understand the global burden of childhood sepsis by analyzing data from multiple countries to improve future treatment strategies.

Contribution

The study introduces a multi-country retrospective observational protocol to analyze sepsis in children, focusing on low- and middle-income countries.

Findings

The study will analyze the incidence, severity, and outcomes of childhood sepsis across multiple countries.

It will collect data on vital signs, treatments, and outcomes to inform future interventional trials.

Ethics approval and data dissemination plans are in place to ensure transparency and impact.

Abstract

Improving outcomes from sepsis in children is a WHO Global Health Priority, yet mortality from sepsis remains high, particularly in low- and middle-income countries (LMICs). This database from children with community-acquired childhood sepsis in LMICs and some high-income countries will allow analysis of the burden of disease, including incidence, severity and outcomes. Understanding these aspects of sepsis care is fundamental for the design and conduct of future international interventional trials to improve childhood sepsis outcomes.

This multicountry retrospective observational study will include children up to 18 years of age presenting to emergency departments with suspected sepsis, defined as admission to hospital for treatment with intravenous antibiotics plus (1) a provisional diagnosis of sepsis and/or (2) treatment for suspected sepsis (operationalised as the administration of one or more fluid bolus to treat impaired perfusion or vasoactive infusion). Presenting characteristics, management and outcomes will be collected. These will include vital signs, serum biomarkers, intravenous fluid administration for the first 24 hours of hospitalisation, organ support therapies delivered, antimicrobial use, microbiological diagnoses, hospital and intensive care unit length of stay, and mortality censored at hospital discharge or 30 days from enrolment (whichever occurs first).

Central ethics approval was received from the Royal Children’s Hospital of Melbourne, Australia Human Research Ethics Committee (HREC/100648/RCHM-2023). Each international site will be required to obtain local Institutional Research Ethics Board approval. The findings will be disseminated in peer-reviewed journals, at academic conferences and through lay media. A cleaned study database and individual site-level data will be made available to site investigators upon completion of the study.

This study was registered with the Australian and New Zealand Clinical Trials Registry on 23 January 2024 prior to commencement of recruitment (ACTRN12624000052538).
