Alert fatigue is the reduced attention that can develop when clinicians face repeated warnings, especially warnings that are irrelevant, repetitive, or difficult to act on. In nursing, the term may refer to EHR messages or device notifications. This article focuses on electronic clinical decision support; device alarm management also requires equipment-specific policies.
An alert should help resolve a clinical decision. Counting how many warnings a system produces does not show how many useful interventions it provides.
Why the same alert can help or hinder
The SAFER decision-support guide recommends informative, actionable, patient-specific notifications at appropriate points in the workflow. It also recommends restricting interruptive alerts to the most critical warnings. An interruption has a cost: the nurse must stop, interpret the message, decide whether it applies, and return to the original task.
A warning may be clinically sound but poorly placed. A nurse may receive it after the relevant action, while entering historical information, or when another team member owns the decision. Repeatedly presenting that warning does not repair the mismatch.
Investigate the reason for overrides
A high override rate is a signal to investigate, not proof that users are careless or that the alert should be deleted. Review actual cases with the affected clinicians. Was the patient already receiving the intended intervention? Was the source information wrong? Did the warning explain what action was expected? Was an appropriate exception possible?
Separate the alert's trigger from its presentation. A correct trigger may need clearer wording or a better recipient. An inaccurate trigger may need a change in data definitions or logic. Both problems can exist at once.
Illustrative review
Consider an illustrative reminder that appears each time a nurse opens a record, even after the nurse has documented why the suggested intervention is temporarily inappropriate. The team examines whether the reason can be recorded in a structured way and whether a clinically approved suppression period is possible.
The goal is to preserve a useful reminder when the patient becomes eligible again, while avoiding repeated demands for the same decision. Any suppression rule needs clinical approval and testing for the situations in which it could hide a necessary warning.
Measure what matters
A local improvement review might compare alerts per relevant encounter, duplicate alerts, the proportion that lead to an appropriate action, and reports of missed warnings. Document the denominator: an alert count per admission is not the same as a count per medication administration.
Do not set a universal acceptable override percentage. The meaning depends on the intervention and the range of legitimate exceptions. The SAFER guide recommends reviewing alerts using clinician feedback and override information, within a governance process.
Nurses should report burdensome patterns through the designated safety or informatics channel rather than independently disabling protections. The strongest report describes the clinical task, when the warning appeared, what it asked for, and why the available response did not fit the situation.
If the alert appears at the wrong point in a task, map the workflow before changing its wording.
