A sepsis staging system focused on predisposition, insult, host response and organ failure may provide a useful basis for risk stratification. Knowledge on interactions among predisposing factors, insult characteristics and host response might help us to improve our understanding on sepsis pathophysiology and allow more individual therapeutic approach. Recent clinical studies documented the clinical importance of PIRO approach for severity stratification in septic patients in intensive care unit, and also for specific conditions such as community acquired pneumonia and ventilator associated pneumonia , with a good performance for outcome prediction. In this review we describe how this new concept can be used in clinical practice and provide some insights on its usefulness to facilitate the stratification and potential for enrollment in clinical trials of sepsis therapies.

Despite recent advances in diagnosis and care of critically ill patients sepsis related mortality rate remains unacceptably high. Therefore, new methods of evaluation are necessary to provide an earlier and more accurate characterization of septic patients. Based on the (oncologic) TNM system, the PIRO concept was introduced as a new staging system for sepsis in order to assess risk and predict prognosis, with potential to assist in inclusion of patients in clinical studies and estimate the probability of response of patients to specific therapeutic interventions.
