Monitor-Watcher Use, Nurses' Knowledge of Electrocardiographic Monitoring, and Arrhythmia Detection

Am J Crit Care. 2021 Jan 1;30(1):38-44. doi: 10.4037/ajcc2021122.

Abstract

Background: Electrocardiographic telemetry monitors are ubiquitous in hospitals. Dedicated monitor watchers, either on the unit or in a centralized location, are often responsible for observing telemetry monitors and responding to their alarms. The impact of use of monitor watchers is not known.

Objectives: To evaluate the association of monitor-watcher use with (1) nurses' knowledge of electrocardiographic (ECG) monitoring and (2) accuracy of arrhythmia detection.

Methods: Baseline data from 37 non-intensive care unit cardiac patient care areas in 17 hospitals in the Practical Use of the Latest Standards for Electrocardiography trial were analyzed. Nurses' knowledge (n = 1136 nurses) was measured using a validated, 20-item online test. Accuracy of arrhythmia detection (n = 1189 patients) was assessed for 5 consecutive days by comparing arrhythmias stored in the monitor with nurses' documentation. Multiple regression was used to evaluate the association of use of monitor watchers with scores on the ECG-monitoring knowledge test. The association of monitor-watcher use with accuracy of arrhythmia detection was examined by χ2 analysis.

Results: Of the 37 units, 13 (35%) had monitor watchers. Use of monitor watchers was not independently associated with ECG-monitoring knowledge (P = .08). The presence of monitor watchers also was not significantly associated with the accuracy of arrhythmia detection (P = .94).

Conclusion: Although the use of monitor watchers was not associated with diminished nurses' knowledge of ECG monitoring, it also was not associated with more accurate arrhythmia detection. If implementing a monitor-watcher program, critical safety points, such as ensuring closed-loop communication, must be considered.
