Objective: To investigate the predictive value of the blood urea nitrogen to serum albumin ratio (BUN/Alb) for in-hospital all-cause mortality risk in acute pancreatitis (AP) patients admitted to the intensive care unit (ICU). Methods: A retrospective analysis was conducted on clinical data from 904 critically ill AP patients in the MIMIC-IV database. BUN/Alb served as the exposure variable, and in-hospital all-cause mortality as the outcome variable. Patients were categorized into survival (n = 789) and non-survival (n = 115) groups. Baseline characteristics were compared between groups. Logistic regression, trend tests, restricted cubic spline curves, and subgroup analyses were employed to explore the relationship between BUN/Alb and mortality, as well as its predictive value. Results: Compared with the survival group, non-survivors were older, had higher proportions of atrial fibrillation and acute myocardial infarction comorbidities, and exhibited elevated serum anion gap, blood urea nitrogen, serum creatinine, blood glucose, white blood cell count, blood lactate, plasma crystalloid osmotic pressure, sodium and potassium levels, SAPS II scores, SOFA scores, and longer ICU stays. They were also more likely to receive vasoactive medications (all P < 0.05). Fully adjusted multivariate logistic regression identified BUN/Alb as a significant independent predictor of mortality in AP patients (OR = 1.05, 95% CI: 1.03~1.08, P < 0.001). When BUN/Alb was divided into quartiles, mortality rates progressively increased with ascending BUN/Alb quartiles (P for trend < 0.05). Restricted cubic spline analysis revealed a positive linear correlation between BUN/Alb and in-hospital mortality. Subgroup analyses demonstrated significant interaction effects between hypertension, diabetes, chronic kidney disease, vasoactive medication use, and the association of BUN/Alb with mortality (P for interaction <0.05).
