Prognostic Value of Scoring Systems in Elderly Sepsis-Associated AKI Patients: A Multicenter Retrospective Cohort Study

65) than sensitivity values in our dataset. Furthermore, while urinary tract infection was associated with increased mortality in elderly AKI patients, our subsequent analysis demonstrated its limited predictive capacity for 28-day and 90-day mortality outcomes.ConclusionIn our cohort of elderly sepsis-AKI patients, SAPS II demonstrated the strongest observed prognostic performance for both 28- and 90-day mortality compared to MELD, LODS, and Charlson scores. These findings suggest SAPS II may be valuable for risk stratification in clinical decision-making for this high-risk population, though further validation is warranted.
