Abstract: Objective: To implement evidence-based practice and evaluate its effectiveness based on the evidence of alarm management of ECG monitor, so as to provide reference for improving alarm management strategies. Methods: Using the continuous quality improvement model of evidence as a theoretical framework, evidence-based practice was applied to the pediatric emergency department of a tertiary grade A specialized hospital in Guangzhou from March to December 2023 according to the process of evidence acquisition, current status review, evidence introduction, and effect evaluation. The differences of ECG monitor alarms occurrence, nurses' alarm fatigue level, nurses' alarm response time, and review indicators implementation rate before and after the evidence-based practice were compared. Results: Fifteen pieces of evidence were ultimately included and translated into 15 review indicators. After evidence-based practice, the incidence of ECG monitor false alarms decreased from 75.99% to 44.27%. Nurses' alarm fatigue scores decreased from 20.97±5.22 to 16.67±8.28 (P<0.05). Nurses' response time to ECG monitor alarm was shortened from (396.95±109.06) seconds to (352.18±124.84) seconds (P<0.01). Among the 15 review indicators, the implementation rate of 14 review indicators had improved. Conclusion: Applying the evidence of ECG monitor alarm management to clinical nursing practice can help reduce the incidence of invalid alarms, alleviate nurses' alarm fatigue, and improve alarm management.
