Methods: We retrospectively analyzed 136 patients aged ≥65 years who underwent emergency HD between January 2023 and June 2025. Demographic, clinical, and laboratory parameters were collected. Logistic regression was used to identify predictors of in-hospital mortality, and ROC curve analyses were performed to assess predictive performance. Results: Of the 136 patients, 31 (22.8%) died during hospitalization. Non-survivors were older (median 79 vs. 73 years, p=0.010), had lower systolic blood pressure (SBP) (120 vs. 140 mmHg, p=0.014), and exhibited higher blood urea nitrogen (BUN) (89 vs. 66 mg/dl, p=0.025) and serum phosphorus (5.45 vs. 4.20 mg/dl, p <0.001), along with lower pH (7.24 vs. 7.28, p=0.014). Logistic regression confirmed advanced age, absence of chronic kidney disease (CKD), low SBP, elevated BUN, high phosphorus, and low pH as independent predictors of in-hospital mortality. Serum calcium was also modestly associated with mortality. Conclusion: In geriatric patients undergoing emergency HD, advanced age, absence of CKD, hypotension, elevated BUN, hyperphosphatemia, and severe metabolic acidosis were significant predictors of in-hospital mortality. These findings highlight the importance of early recognition and management of modifiable risk factors to improve outcomes in this vulnerable population.}, number={5}, publisher={MediHealth Academy Yayıncılık}, organization={yok}
