Enhancing early diagnosis of septic shock and Sepsis-induced Acute Kidney Injury (S-AKI) in patients with sepsis

Background: Sepsis and its most severe form, septic shock, are major public health crises causing substantial morbidity, mortality, and financial burdens in hospitals, particularly as leading causes of acute kidney injury (AKI) in ICUs. Sepsis-induced AKI carries a higher mortality rate and economic burden compared to other causes of AKI or sepsis alone. Although septic shock and sepsis-induced AKI can be reversed with timely intervention, the narrow window for effective treatment underscores the importance of early diagnosis. The study aims to develop a predictive model for the early diagnosis of septic shock and sepsis-induced AKI within the crucial 48 hours of hospital admission. The model utilized the innovative Maximum Partial SOFA (Max Pt-SOFA) score, vital signs, and laboratory biomarkers within the first six hours of hospital admission, which was in line with Sepsis-3 guidelines. The Max Pt-SOFA score addresses the limitations of the traditional SOFA score, such as its restriction to ICU settings, failure to reflect the patient's condition accurately, and its constraints on early assessments.

Method: In this retrospective cohort study, we analyzed electronic health records from Geisinger Health System, spanning from January 1, 2007, to June 3, 2016, identifying a total of 3,038 and 893 patients met the criteria for sepsis and septic shock within 48 hours of admission, respectively. Excluding 145 patients diagnosed with AKI at admission, 2,043 were diagnosed with Sepsis-induced AKI within 48 hours. Among the S-AKI cohort, 1384 cases originated from sepsis (n=2913), and 659 cases originated from septic shock (n=873). the Max Pt-SOFA score is re-calculated with every change in the parameters of the six organ systems within 48 hours of admission. The time to organ dysfunction was captured when the Max Pt-SOFA reached two or more, therefore meeting the sepsis-3. Additionally, The Max Pt-SOFA score was calculated within six hours of admission to predict septic shock and sepsis-induced AKI development. We incorporated forty-four variables, including comorbidities, the Max Pt-SOFA score, laboratory biomarkers, and vital signs within six hours of admission, into a stepwise logistic regression model to predict septic shock and sepsis-induced AKI within 48 hours of admission. The model successfully identified several key predictors, which were utilized to construct our comprehensive model. We conducted multiple imputations, Wilcoxon rank sum test, Chi-Square tests, sensitivity analysis, and 10-fold cross-validation, with odds ratios and 95% CIs reported to validate the model.

Results: Our predictive model demonstrated excellent performance with an AUC of 0.8998 in identifying patients at risk of septic shock within the first 48 hours of admission. The novel Max Pt-SOFA score, calculated within the first six hours, emerged as a significant predictor (value: 1.461, CI: 1.404-1.521), underscoring its significance in early diagnosis. Additionally, the Max Pt-SOFA score (1.048, CI: 1.021-1.076), along with other early predictors such as creatinine (2.712, CI: 2.403-3.061), proved significant in predicting sepsis-induced AKI. The model also showed strong predictive capability for sepsis-induced AKI with an AUC of 0.7914. For both predictive models, The sensitivity analyses indicated that the final logistic regression models are relatively robust to the issue of data missingness. However, the Hosmer and Lemeshow tests, used to assess the models' fit, suggested room for further refinement (Pr>ChiSq <0.05)

Conclusion: The Max Pt-SOFA score calculated within the first six hours of admission stands out for its predictive value in early septic shock and sepsis-induced AKI detection. This facilitates timely identification and intervention, thereby improving patient outcomes.
