Attitudes Surrounding Continuous Telemetry Utilization by Providers at an Academic Tertiary Medical Center

From the Johns Hopkins Bayview Medical Center, Baltimore, MD (Drs. Johnson, Knight, Maygers, and Zakaria), and Duke University Hospital, Durham, NC (Dr. Mock).

Abstract

• Objective: To determine patterns of telemetry use at a tertiary academic institution and identify factors contributing to noncompliance with guidelines regarding telemetry use.
• Methods: Web-based survey of 180 providers, including internal medicine residents and cardiovascular disease fellows, hospitalists, non-hospitalist teaching attending physicians, nurse practitioners, and physician assistants.
• Results: Of the 180 providers surveyed, 67 (37%) replied. Most providers (76%) were unaware of guidelines regarding appropriate telemetry use and 85% selected inappropriate diagnoses as warranting telemetry. Only 21% routinely discontinued the telemetry order within 48 hours.
• Conclusions: Many providers at a tertiary academic institution utilize continuous telemetry inappropriately and are unaware of telemetry guidelines. These findings should guide interventions to improve telemetry utilization.

For many decades, telemetry has been widely used in the management and monitoring of patients with possible acute coronary syndromes (ACS), arrhythmias, cardiac events, and strokes [1]. In addition, telemetry has often been used in other clinical scenarios with less rigorous data supporting its use [2–4]. As a result, in 2004 the American Heart Association (AHA) issued guidelines providing recommendations for best practices in hospital ECG monitoring. Indications for telemetry were classified into 3 diagnosis-driven groups: class I (indicated in all patients), class II (indicated in most patients, may be of benefit) and class III (not indicated, no therapeutic benefit) [2]. However, these recommendations have not been widely followed and telemetry is inappropriately used for many inpatients [5,6].

There are several reasons why clinicians fail to adhere to guidelines, including knowledge deficits, attitudes regarding the current guidelines, and institution-specific factors influencing practitioner behaviors [7]. In response to reports of widespread telemetry overuse, the Choosing Wisely Campaign of the American Board of Internal Medicine Foundation has championed judicious telemetry use, advocating evidence-based, protocol-driven telemetry management for patients not in intensive care units who do not meet guideline-based criteria for continuous telemetry [8].

In order to understand patterns of telemetry use at our academic institution and identify factors associated with this practice, we systematically analyzed telemetry use perceptions through provider surveys. We hypothesized that providers have misperceptions about appropriate use of telemetry and that this knowledge gap results in overuse of telemetry at our institution.

Methods

Setting

Johns Hopkins Bayview Medical Center is a 400-bed academic medical center serving southeastern Baltimore. Providers included internal medicine residents and cardiovascular disease fellows who rotate to the medical center and Johns Hopkins Hospital, hospitalists, non-hospitalist teaching attending physicians, nurse practitioners (NPs), and physician assistants (PAs).

Current Telemetry Practice

Remote telemetric monitoring is available in all adult, non-intensive care units of the hospital except for the psychiatry unit. However, the number of monitors are limited and it is not possible to monitor every patient if the wards are at capacity. Obstetrics uses its own unique cardiac monitoring system and thus was not included in the survey. Each monitor (IntelliVue, Philips Healthcare, Amsterdam, Netherlands) is attached to the patient using 5 lead wires, with electrocardiographic data transmitted to a monitoring station based in the progressive care unit, a cardio-pulmonary step-down unit. Monitors can be ordered in one of 3 manners, as mandated by hospital policy:

1. Continuous telemetry – Telemetry monitoring is uninterrupted until discontinued by a provider.
2. Telemetry protocol – Within 12 hours of telemetry placement, a monitor technician generates a report, which is reviewed by the nurse caring for the patient. The nurse performs an electrocardiogram (ECG) if the patient meets pre-specified criteria for telemetry discontinuation, which includes the absence of arrhythmias, troponin elevations, chest pain, or hemodynamic instability. The repeat ECG is then read and signed by the provider. After these criteria are met, telemetry can be discontinued.
3. Stroke telemetry protocol – Telemetry is applied for 48 hours, mainly for detection of paroxysmal atrial fibrillation. Monitoring can be temporarily discontinued if the patient requires magnetic resonance imaging, which interferes with the telemetric monitors.

When entering any of the 3 possible telemetry orders in our computerized provider order entry system (Meditech, Westwood, MA), the ordering provider is required to indicate baseline rhythm, pacemaker presence, and desired heart rate warning parameters. Once the order is electronically signed, a monitor technician notes the order in a logbook and assigns the patient a telemeter, which is applied by the patient’s nurse.

If a monitored patient develops any predefined abnormal rhythm, audible alerts notify monitor technicians and an alert is sent to a portable telephone carried by the patient’s assigned nurse. Either the monitoring technician or the nurse then has the discretion to silence the alarm, note it in the chart, and/or contact the patient’s provider. If alerts are recorded, then a sample telemetry monitoring strip is saved into the patient’s paper medical chart.
