Virtual Monitoring Technician Performance in High-Fidelity Simulations of Remote Patient Monitoring: An Exploratory...

Area of Science:

• Healthcare Technology
• Human Factors Engineering
• Patient Safety

Background:

• Virtual Monitor Technicians (VMTs) are essential for remote inpatient telemetry monitoring.
• Little is known about VMT workload, performance fluctuations, and patient safety implications.

Purpose of the Study:

• To evaluate VMT workload and performance changes over time in a simulated telemetry monitoring environment.
• To identify research directions for enhancing VMT performance and patient safety.

Main Methods:

• A high-fidelity simulation replicating remote telemetry stations and documentation was developed.
• Twelve VMTs participated in a 1-hour session, with workload measured by NASA-Task Load Index and performance assessed via alert detection and escalation times.

Main Results:

• Workload significantly increased (NASA-TLX score from 38 to 64), driven by mental and temporal demands.
• VMT performance did not decline, maintaining a 52% correct response rate.
• Response times varied by alert urgency, with advisory alerts taking significantly longer to recognize.

Conclusions:

• The study establishes a baseline for VMT workload expectations, showing increased demands without performance degradation.
• VMTs are most effective with urgent alerts; accuracy for non-urgent alerts requires improvement.
• Further research is needed to enhance VMT response accuracy beyond the observed 52%.
