Technological Intervention to Improve Alarm Management in Acute Care Telemetry Units

Area of Science:

• Medical Devices
• Patient Safety
• Nursing Informatics

Background:

• Continuous telemetry monitoring is crucial for patient safety.
• Excessive monitor alarms contribute to alarm fatigue, potentially leading to delayed responses.
• Patient outliers generate a disproportionate number of alarms, exacerbating the issue.

Purpose of the Study:

• To evaluate a technological intervention designed to reduce excessive telemetry alarms.
• To assess the impact of real-time notifications on registered nurses' (RNs) alarm management practices.

Main Methods:

• A technological alert system was implemented at a large academic medical center.
• RNs received mobile phone notifications when patient alarms exceeded a defined threshold (400% above the unit's 7-day average).
• Alarm data was analyzed pre- and post-intervention across four acute care telemetry units.

Main Results:

• A statistically significant reduction in average alarm duration was observed (P < 0.001), with a decrease of 8.07 seconds.
• However, alarm frequency significantly increased post-intervention (χ2(3) = 34.83, P < 0.001).

Conclusions:

• Technological interventions notifying RNs to adjust alarm parameters may decrease alarm duration.
• Further research is required to understand the increase in alarm frequency and its implications.
• Findings suggest potential improvements in RN telemetry management and alarm fatigue awareness, warranting further investigation.
