Abstract:
Objective
To investigate the correlation between the international normalized ratio(INR) and outcomes in patients with sepsis-associated acute kidney injury(SA-AKI)using data from the Medical Information Mart for Intensive Care-Ⅳ (MIMIC-Ⅳ).
Methods
Using a retrospective queue design,information on adult SA-AKI patients with ICU admission records was extracted from the MIMIC-Ⅳ 2.0.Restricted cubic spline models and multivariable Cox proportional hazards regression were employed to evaluate the nonlinear relationship between INR levels and mortality. Patients were stratified by an ICU admission 24-hour INR cutoff for Kaplan-Meier survival analysis.
Results
Elevated INR was independently associated with increased mortality (adjusted HR=1.73, 95%CI: 1.59~1.88, P<0.001), and it shows a non-linear relationship with the prognosis of SA-AKI patients (P<0.001), with a cutoff value of 1.4.
Conclusion
High INR is an independent risk factor for predicting in-hospital mortality in SA-AKI patients. In the treatment process of SA-AKI patients, attention should be paid to the comprehensive evaluation of INR levels and other indicators.
