Objective: This systematic review and meta-analysis aimed to research on the effect of the interventions developed to reduce alarm fatigue in intensive care units. Methods: Three researchers independently searched 14 databases. The databases were scanned to access articles published between 01.01.2010 and 31.12.2022. The Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instruments (JBI-MAStARI) were used to assess methodological quality. The study is preregistered on PROSPERO (CRD42023387649). Results: Of the 11632 studies, 19 articles that met the criteria were included in the systematic review, and seven articles were included in the meta-analysis study. While the effect of the strategies applied in reducing alarm fatigue was found to be significant in five articles (p < 0.05). The meta-analysis results showed that strategies implemented to reduce alarm fatigue may have a significant effect (p > 0.05) in reducing nurses' alarm fatigue. Seven of the articles included in the systematic review showed that the implemented interventions indicated that decline in the perception of the existence of non-actionable/false alarms. After the intervention, the proportion of nurses who agreed with the statement that non-actionable/false alarms interrupted patient care increased, while in another study, the number of nurses who believed that alarms were missed and/or responses were delayed increased. Conclusion: In this study, the effect size obtained from all articles was not significant and showed that the interventions may not have an effect on reducing alarm fatigue.
