Introduction: Though many scoring systems for prognostication of sepsis are available in the intensive care set-up, predisposition, insult, response, and organ dysfunction (PIRO) score helps to assess each patient and evaluate response to therapy. There are few studies comparing the efficacy of PIRO score with other sepsis scores. Hence, our study was planned to compare PIRO score with acute physiology and chronic health evaluation IV (APACHE IV) score and sequential (sepsis-related) organ failure assessment (SOFA) score in predicting the mortality of intensive care patients with sepsis.
Materials and methods: This prospective cross-sectional study was done in the medical intensive care unit (MICU) from August 2019 to September 2021 among patients above 18 years of age with the diagnosis of sepsis. Predisposition, insult, response, and organ dysfunction score, SOFA score, and APACHE IV score on admission and at day 3 were calculated and statistically analyzed in the terms of outcome.
Results: A total of 280 patients fulfilling the inclusion criteria were included in the study, the mean age was 59.38 ± 15.9 years. There was a significant association of PIRO score, SOFA score, and APACHE IV score on admission and at day 3 with mortality (p-value <0.05). Among all three parameters, the PIRO score on admission and at day 3 was the best predictor of mortality at cut-off points of >14 and >16 with 92.50% and 96.50% chances of correctly predicting mortality, respectively.
Conclusion: Predisposition, insult, response, and organ dysfunction score can be considered as a strong predictor of prognostication of patients with sepsis admitted to the intensive care unit (ICU) and predict mortality. It should be routinely used as it is a simple and comprehensive score.
