ObjectivesTo determine critical care nurses' knowledge of alarm fatigue and practices toward alarms in critical care settings.Research Methodology/DesignA cross-sectional survey using an adaptation of The Health Technology Foundation Clinical Alarms Survey.SettingA sample of critical care nurses (n = 250) from 10 departments across six hospitals in Ireland.ResultsA response rate of 66% (n = 166) was achieved. All hospital sites reported patient adverse events related to clinical alarms. The majority of nurses (52%, n = 86) did not know or were unsure, how to prevent alarm fatigue. Most nurses (90%, n = 148) agreed that non-actionable alarms occurred frequently, disrupted patient care (91%, n = 145) and reduced trust in alarms prompting nurses to sometimes disable alarms (81%, n = 132). Nurses claiming to know how to prevent alarm fatigue stated they customised patient alarm parameters frequently (p = 0.037). Frequent false alarms causing reduced attention or response to alarms ranked the number one obstacle to effective alarm management; this was followed by inadequate staff to respond to alarms. Only 31% (n = 50) believed that alarm management policies and procedures were used effectively.ConclusionAlarm fatigue has the potential for serious consequences for patient safety and answering numerous alarms drains nursing resources.Copyright © 2018 Elsevier Ltd.
