Overview of the Phoenix sepsis criteria
The podcast episode discusses the landmark paper, the Phoenix sepsis criteria, which was developed and validated by an international group of researchers. The criteria shift from the previous consensus definitions to a data-driven approach based on organ dysfunction. The podcast highlights the limitations of the previous definitions, including their lack of specificity and lack of inclusion of data-driven approaches. The new criteria focus on four core organ systems: respiratory, cardiovascular, neurologic, and coagulation. These organ systems were chosen based on their contribution to mortality in patients with infection. The podcast describes the methodology used, including the use of stack regressions and penalized regression models. The results of the study showed that the four organ system model performed similarly to the eight organ system model, leading to the selection of the four organ system Phoenix sepsis score. It is noted that the eight organ system model, called Phoenix Eight, is still valuable for research and management purposes.
