Prognostic Value of Shock Index, Modified Shock Index, and Age Shock Index in Patients with Sepsis in the Intensive Care Unit

Objective: We aimed to evaluate the usability of the Shock Index (SI), Modified Shock Index (MSI), and Age Shock Index (ASI) in predicting clinical outcomes and mortality in sepsis patients followed in the intensive care unit. Methods: Records of patients admitted to the intensive care unit of Muş State Hospital between January 2022, and April 2024, who developed sepsis were retrospectively recorded from the hospital data system. Results: A total of 127 patients were included in the study. The average age of these patients was found to be 50.83±12.01 years. The average age of discharged patients was 46.14±10.12 years, while the average age of deceased patients was 58.54±10.89 years. In the gender distribution, 63.78% of all patients were male and 36.22% were female (p=0.028). SI was determined as 0.88±0.33 in discharged patients and 1.11±0.32 in deceased patients (p=0.0002). MSI was found to be 1.45±0.33 in discharged patients and 1.68±0.32 in deceased patients (p=0.00001). ASI was determined as 40.73±18.41 in discharged patients and 64.94±22.85 in deceased patients (p=0.0001). The cut-off value for SI was found to be 0.76, with an AUC value of 0.69. The cut-off value for the MSI was determined to be 1.35, with an AUC value of 0.72. The cut-off value for the ASI was found to be 38.76, with an AUC value of 0.85. Conclusion: All three shock indices were statistically significant in predicting mortality in sepsis patients. We believe they are valuable indices that can be used bedside and non-invasively in intensive care units.
