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.
