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

Discussion

Consistent with previous studies [3–5,9–15], the majority of providers at our institution do not think continuous telemetry is appropriately utilized. Most survey respondents acknowledged a lack of awareness surrounding current guideline recommendations, which could explain why providers often do not follow them. Despite conceding their knowledge deficits, providers assumed their practice patterns for ordering telemetry were “appropriate”(ie, guideline-supported). This assertion may be incorrect as the majority of providers in our survey chose at least 1 non–guideline-supported indication for telemetry. Other studies have suggested additional reasons for inappropriate telemetry utilization. Providers may disagree with guideline recommendations, may assign lesser importance to guidelines when caring for an individual patient, or may fall victim to inertia (ie, not ordering telemetry appropriately simply because changing one’s practice pattern is difficult) [7].

In addition, the majority of our providers perceived telemetry overuse, which has been well-recognized nationwide [4]. While we did not assess this directly, other studies suggest that providers may overuse telemetry to provide a sense of reassurance when caring for a sick patient, since continuous telemetry is perceived to provide a higher level of care [6,15–17]. Unfortunately, no study has shown a benefit for continuous telemetry when placed for non-guideline-based diagnoses—whether for cardiac or non-cardiac diagnoses [3,9–11,13,14]. Likewise, the guidelines suggest that telemetry use should be time-limited, since the majority of benefit is accrued in the first 48 hours. Beyond that time, no study has shown a clear benefit to continuous telemetry [2]. Therefore, telemetry overuse may lead to unnecessarily increased costs without added benefits [3,9–11,13–15,18].

Our conclusions are tempered by the nature of our survey data. We recognize that our survey has not been previously validated. In addition, our response rates were low. This low sample size may lead to under-representation of diverse ideas. Also, our survey results may not be generalizable, since our study was conducted at a single academic hospital. Our institution’s telemetry ordering culture may differ from others, therefore making our results less applicable to other centers.

Despite these limitations, our results aid in understanding attitudes that surround the use of continuous telemetry, which can shape formal educational interventions to encourage appropriate guideline-based telemetry use. Since our providers agree on the need for more education about the guidelines, components such as online modules or in-person lecture educational sessions, newsletters, email communications, and incorporation of AHA guidelines into the institution’s automated computer order entry system could be utilized [17]. Didactic interventions could be designed especially for trainees given their overall lack of familiarity with the guidelines. Another potential intervention could include supplying providers with publically shared personalized measures of their own practices, since providers benefit from reinforcement and individualized feedback on appropriate utilization practices [19]. Previous studies have suggested that a multidisciplinary approach to patient care leads to positive outcomes [20,21], and in our experience, nursing input is absolutely critical in outlining potential problems and in developing solutions. Our findings suggest that nurses could play an active role in alerting providers when patients have telemetry in use and identifying patients who may no longer need it.

In summary, we have shown that many providers at a tertiary academic institution utilized continuous telemetry inappropriately, and were unaware of guidelines surrounding telemetry use. Future interventions aimed at educating providers, encouraging dialogue between staff, and enabling guideline-supported utilization may increase appropriate telemetry use leading to lower cost and improved quality of patient care.
