Risk Factor Analysis and Nomogram for Predicting 28-day in-hospital Mortality in ICU Patients with Liver Necrosis.

INTRODUCTION

The mortality risk factors in intensive care unit (ICU) patients with liver necrosis (LN) remain unclear. This study aimed to develop a prediction model for mortality risk in LN patients to assist clinical practice.

METHODS

We enrolled 1153 acute and subacute LN patients from the MIMIC-III database, randomly divided into training and validation cohorts. LASSO regression was used to screen risk factors. A multiple logistic regression model and nomogram were established for 28-day mortality prediction. The model was assessed by AUC, calibration curves, and DCA.

RESULTS

LASSO regression identified age, gender, ethnicity, marital status, bicarbonate, bilirubin, hemoglobin, electrolytes, heart rate, temperature, and SpO₂as independent risk factors.

DISCUSSION: Although there is currently no suitable model for predicting patients with sepsis, the model we have constructed includes some factors that were previously considered independent but were not as significant. This time, we have highlighted the more important positions. Our model will provide ideas for predicting liver necrosis insepsis.

CONCLUSION

Our model integrates previously underappreciated predictors and emphasizes their clinical significance, providing novel insights for predicting LN in patients with sepsis.
