The LIAISE study is a prospective observational study comparing the performance of load-incorporating echocardiographic parameters and conventional parameters in predicting adverse events among adult patients presenting to the ICU with sepsis. It will be conducted in hospitals in Australia, Hong Kong, South Africa, and Canada, with 199 patients recruited over 2 years. All included patients will receive an regular echocardiographic assessment and their haemodynamic parameters will be simultaneously recorded. Participants will be followed for up to 1 year after enrolment. Load incorporating parameters will be derived from regularly obtained echocardiography and haemodynamic data during offline analysis. The predictive value of cardiac parameters will be evaluated based on their statistical association with clinical outcomes.
Adults ≥ 18 years old.
Clinically suspected of defined sepsis
Sepsis-induced hypotension or hypoperfusion (arterial or venous blood lactate ≥2.0 mmol/L OR mean artery pressure ≤65 mmHg over 30 mins OR at least one vasoactive or inotropic agent administered).
At least one dose of an IV antimicrobial has been commenced.
Suspected or confirmed pregnancy.
Any severe concomitant diseases with limited life expectancy <30 days.
