The degree of hemodynamic support by vasoactive drugs in critically ill patients is often considered one of the markers of disease severity. The sequential organ failure assessment (SOFA), European system for cardiac operative risk evaluation II (EuroScore II), and other scores only roughly quantify the drug support of cardiovascular system. When patients need large doses of vasoactive drugs, the mortality increases accordingly. The vasoactive-inotropic score (VIS) objectively quantifies the degree of cardiovascular support using a simple formula that standardizes the dose of different agents, and it is recommended as a simple, effective, and accurate prognostic indicator. In recent years, there are more and more clinical applications and related studies at home and abroad. This paper reviews the application and progress of VIS score in critically ill patients, providing help for doctors to judge the condition and prognosis of patients and guiding the decision-making of diagnosis and treatment.
