Key result
Overtime and false alarms link to three distinct alarm fatigue profiles among ICU nurses.
Why the study?
Clinical alarms from various medical instruments and equipment are becoming a new challenge for staff in intensive care units.
What are the latent profiles of alarm fatigue and their predictors among ICU nurses?
What are the latent profiles of alarm fatigue and their predictors among ICU nurses?
ICU nurses experience medium-high levels of alarm fatigue, which can be categorized into three latent profiles influenced by workplace and cognitive factors, highlighting the need for tailored interventions.

May support profile-specific interventions for ICU nurse well-being; cross-sectional data leaves open causality and needs prospective validation.
The clinical alarms from various medical instrument and equipment are becoming a new challenge for staff in intensive care unit workplace. This study revealed the latent profiles of alarm fatigue among intensive care unit (ICU) nurses and to explore their predictors. A cross‐sectional survey was conducted from 2023 to 2024 using the nurses' alarm fatigue questionnaire (NAFQ) to measure the alarm fatigue of 725 ICU nurses in China. The overall alarm fatigue of nurses in ICUs is at a medium‐high level. Three classes of alarm fatigue were identified by latent profile analysis and influenced by multiple factors (i.e., whether working overtime, whether having alarm management protocol in the wards, clinical false alarm experience, and alarm function cognition). This study suggests that administrators provide tailored supports and interventions to reduce alarm fatigue of nurses in ICUs based on the characteristics of their alarm fatigue profiles.

Yang et al. (2026) studied this question. Three alarm fatigue profiles were identified among 725 ICU nurses with medium-high fatigue levels, influenced by overtime, alarm protocols, false alarms, and alarm cognition.
