Heparin-Binding Protein As A Prognostic Biomarker of Sepsis and Disease Severity at The Emergency Department.

OBJECTIVE Rapid and early detection of patients at risk to develop sepsis remains demanding. Heparin-binding protein (HBP) has previously demonstrated good prognostic properties in detecting organ dysfunction among patients with suspected infections. This study aimed to evaluate the plasma-levels of HBP as a prognostic biomarker for infection-induced organ dysfunction among patients seeking medical attention at the emergency department. DESIGN Prospective, international multicenter, convenience sample study SETTING:: Four general emergency departments at academic centers in Sweden, Switzerland and Canada. PATIENTS All emergency encounters among adults where one of the following criteria were fulfilled: a) respiratory rate >25 breaths per minute; b) heart rate >120 beats per minute; c) altered mental status; d) systolic blood pressure <100 mm Hg; e) oxygen saturation <90% without oxygen; f) oxygen saturation <93% with oxygen; g) reported oxygen saturation
