Alarm fatigue is a growing concern in our healthcare system and nursing care today. Studies have shown that as many as 86% to 99.4% of alarms that sound by physiological monitors are false-positives that do not result in a change in patient care (Graham, 2010). The primary objective of physiological alarms on the nursing units is to notify the clinicians to a patient’s deteriorating status in order for timely and proper action to be taken before an adverse outcome occurs. Due to the high volume of false-positive alarms, over time, these alarms start to be taken less seriously, slowing reaction time to a possible patient’s problem, or being ignored all together. Alarm fatigue can be challenging due to the fact that it involves both technical …show more content…

Customization allows for patient’s to have tailor made, detailed care and thought put into their healthcare experience and allows for a better outcome. The primary problem with alarm fatigue is the sheer number of ‘nuisance’ alarms caused by clinicians using the factory or hospital based default settings. These default settings do not take into account the type of patient that a clinician is caring for or the degree or severity of their condition. Customizing alarms, instead of using the default settings provided on the equipment, ensures that alarms are valid, actionable, and able to be used to ensure the patient remains free from poor outcomes (Cvach, 2012; DeVaux, 2015; Graham, 2010). The problem with using default alarm settings on a patient, is that when the alarms are triggered, nurses become immune to them, resulting in delayed response times, due to the fact that up to 70% of the alarms that go off are threshold alarms for preset limits (Bridi, 2014). Customization of physiological alarms is the best approach to improve the growing problem of alarm fatigue as evidenced by the reduction of total number of alarms, provides an early warning to potential critical situations, and leading to actionable and clinically significant …show more content…

The problem with lack of monitor education is that nurses continue to use default monitor settings and improperly applying physiological monitors which lead to an increased number of nuisance alarms adding to the growing problem of alarm fatigue. Studies found that a crucial component of tackling alarm fatigue was to educate the nursing staff on monitor settings as well as proper machine usage (Bridi, 2014; Graham, 2010; Devaux, 2015). This included education on individualizing alarm parameters, levels of alarms and their specific alarm tones, preparing the patient’s skin, lead placement, high and medium priority arrhythmia alarms, and QTC monitoring (Bridi, 2014; Graham, 2010; Devaux, 2015). Further research and investment of time is needed on monitor and alarm education as evidenced by the positive and motivated outlook on monitor education in order to decrease monitor alarms on the unit as well as establishing alarm parameters so alarms that occur are purposeful and
