Hemodialysis equipment alarms significantly impact clinical workflow and patient safety. This study aimed to characterize alarm patterns, identify risk factors, and evaluate management effectiveness in hemodialysis facilities. A retrospective cohort analysis was conducted at 1 hemodialysis center from January 2020 to December 2023. Equipment alarm data from hemodialysis stations (Nikkiso, Gambro, and B. Braun) were systematically collected and analyzed. Multivariate regression and machine learning approaches identified risk factors and developed predictive model. Among 4231 recorded alarm events over 32 months, the monthly alarm rate averaged 132. 2 +/- 54. 4 events. The COVID-19 pandemic period (2020-2021) accounted for 82. 2% of alarms, with a significant 78. 3% reduction post-pandemic (P = 0. 022). B. Braun equipment generated 68. 7% of alarms, significantly higher than Gambro (21. 2%) and Nikkiso (10. 1%) devices (P
