Updated SCAI SHOCK Stages Classification

The SCAI SHOCK classification is intended to provide clinicians and researchers with a unified and standardized vocabulary that will translate across all settings. Additionally, the system aims to facilitate recognition of risk for adverse outcomes, potential for benefit from various interventions and prognosis, with the goal of reducing mortality on an individual as well as a national scale.

The latest update includes a 3-axis model that places the shock stage in context with other predictors of mortality, such as etiology, phenotype, and non-modifiable risk factors such as age and frailty. It also provides a more useful cardiac arrest modifier and clarifies the constituent domains of the classification, including physical examination, biochemical, and hemodynamic criteria.
