European Prospective Bloodstream Infection Cohort

Sponsor: University Hospital Freiburg

Summary

Background: Bloodstream infections (BSIs) and sepsis continue to pose significant public health challenges, contributing to high morbidity and mortality worldwide. According to the Global Burden of Diseases Study, BSIs and sepsis are associated with approximately 20% of global deaths. However, the clinical characteristics of BSIs have evolved over recent years, showing significant variability across different countries and continents. The diversity in management standards across regions further complicates the generalization and transferability of research findings. Despite the critical need for comprehensive data, BSI research in Europe remains fragmented, often limited to national-level studies. Project Aim: The EPIC-BSI project aims to address these challenges by establishing a multinational, collaborative bloodstream infection cohort across Europe and globally. The primary objectives are to: * Integrate national BSI research into a cohesive multinational cohort that enable large-scale comparative research by standardizing BSI incidence data, diagnostic and therapeutic approaches, and patient outcomes across European countries and beyond. * Monitor shifts in BSI characteristics, including the emergence of multi-drug resistant organisms, and changes in risk groups, diagnostics, and therapies. * Create a foundation for future studies and collaborations, such as integrating BSI data with international antibiotic usage, population data, health policy data, or by biobanking blood-borne pathogens for sequencing. The study is divided into three arms focusing on BSI epidemiology (EPIC-BSI registry), diagnostics (EPIC-BSI Diagnostic Study) and management (EPIC-BSI Management study). The EPIC-BSI Management study is partitioned in different levels of data contribution to reduce barriers for centres and enable broad participation. Specific Objectives and Endpoints: EPIC-BSI Registry: * Primary aim/endpoint: Establish an international prospective BSI cohort with anonymized inclusion of all BSI cases from participating centres allowing estimation of BSI incidence by pathogen in the participating centres. * Secondary aims/endpoints: * Analyse the incidence of BSIs across different settings and countries. * Monitor changes in patient demographics (age, gender) and acquisition modes. * Track shifts in antimicrobial resistance patterns. * Review effects of infection control practices on MDRO-BSI frequency EPIC-BSI Diagnostic Study: * Primary aim/endpoint: Biannual evaluation of diagnostic procedures and standards regarding BSI at participating centres * Secondary aims/endpoints: * Assess the availability and use of (new) clinical and microbiological diagnostics. * Identify gaps in diagnostic practices and time lags between scientific evidence, guideline publication and clinical implementation of new diagnostic utilities. EPIC-BSI Management Study: * Primary aim/endpoint: Analyse clinical data from BSI cases to evaluate management practices regarding the effect on in-hospital mortality and outcome on day 90 after onset incl. patient-reported outcomes (Desirability-of-outcome-ranking (DOOR) or health-related quality of life metrics) * Secondary aims/endpoints: * Identify differences in clinical management across countries and hospital types. * Analyse the impact of antimicrobial resistance patterns on clinical outcomes. * Evaluate the effectiveness of different established therapeutic regimens.
