Constantly beeping alarms in hospitals are being linked to patient deaths and other dangers in a new alert from the Joint Commission hospital accrediting group.

The alarms can lead to "noise fatigue," and doctors and nurses sometimes inadvertently ignore the sounds when there's a real patient emergency, possibly resulting in treatment delays that endanger patients. The group says a government database lists more than 500 deaths potentially linked with hospital alarms in recent years.

The commission says hospital leaders need to address the problem and train staffers in safe alarm management.
