The effect of a clinical approach to ventilator alarm management on alarm fatigue in intensive care nurses: a randomized controlled trial.
Article in BMC nursing, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEvery day in intensive care units (ICUs), many alarms from several devices -especially ventilators- are generated, creating a noisy environment, which is on the top of technology-related hazards and may lead to alarm fatigue among nurses. This study aimed to investigate the impact of a clinical approach to ventilator alarm management on nurses' alarm fatigue and alarm frequency in ICUs.
methodsThis randomized controlled trial involved 75 nurses in two general ICUs allocated into control and intervention groups using cluster randomization. In the intervention group (IG), clinical causes and solutions of common ventilator alarms were trained in a 4-hour online webinar. Then, an evidence-based guideline for alarm management was attached to all ventilators in the intervention ICU. Additionally, nurses of the IG were trained virtually and face-to-face regarding the fundamentals of mechanical ventilation and how to manage ventilator alarms for one month. Before and after the intervention, nurses' alarm fatigue and frequency of three common alarms were recorded for five consecutive days. The control group (CG) did not receive the educational content. Data were analyzed using SPSS-26. This study adheres to CONSORT guidelines.
resultsThe baseline characteristics were not significantly different between the groups. Also, alarm fatigue scores of nurses did not significantly differ between groups before the intervention (p = 0.17). In the IG, nurses' alarm fatigue scores significantly decreased from 24.86 ± 6.65 to 20.24 ± 4.39 (p < 0.025) and its difference was significant between the groups (p < 0.001). However, alarm fatigue scores in the CG did not improve significantly after one month. As a secondary outcome, the frequency of three common alarms including high pressure (-34.3%), high minute volume/tidal volume (-28.6%), and high respiratory rate (-25.4%) was reduced after the intervention.
conclusionThis study indicated that training and implementing an evidence-based clinical approach to ventilator alarm management not only reduced nurses' alarm fatigue but also could lead to a significant reduction in the common ventilator alarms frequency.
