Implementation of a Tiered Cardiac Telemetry System: An Operational Blueprint at Mayo Clinic

Area of Science:

• Cardiology
• Biomedical Engineering
• Health Informatics

Background:

• Tiered cardiac telemetry monitoring is evolving with new technologies.
• Wireless cardiac monitoring offers potential for enhanced patient surveillance.

Purpose of the Study:

• To evaluate the operational outcomes of tiered cardiac telemetry using a novel wireless device.
• To assess the precision, speed, and reliability of alerts from a wireless cardiac monitor compared to a hardwired system.

Main Methods:

• An agile methodology was used to test and validate a cellular-connected continuous cardiac monitor (InfoBionic MoMe).
• 162 adult patients were concurrently monitored by both wireless and standard hardwired systems at Mayo Clinic Hospital.
• Data was collected from June 6, 2022, to December 15, 2022.

Main Results:

• The wireless device demonstrated a high correlation of captured events with the standard care model.
• Connectivity improvements reduced alert latency from 3-5 minutes to 30 seconds.
• Delayed alarms occurred in 4.5% of cases due to device damage and 29% due to poor cellular connections.

Conclusions:

• The wireless cardiac monitoring device concept was validated, supporting expanded telemetry capabilities.
• Further technological enhancements and research are necessary before widespread inpatient implementation.
• Advancements in remote monitoring can improve post-discharge care and hospital-based surveillance.
