Abstract 248: Utility of Central Telemetry Monitoring in 2011
Introduction: ECG monitoring via central telemetry (TECG) is commonly used in modern hospitals. Guidelines for the application of TECG are infrequently updated, and the value of TECG in an era of concern over escalating costs is not known. Our institution is critically examining the role of TECG in overall patient safety and needed baseline data on the outcomes of patients undergoing TECG.
Objective: Describe the frequency of clinically important events in patients undergoing TECG.
Methods: During a 3 month period in 2011, 11,520 patient-days of telemetry were surveyed in a large urban multihospital network with central telemetry staffed by trained technicians. Those patients that required a call from a telemetry technician to a nurse and subsequent intervention were included in the study. Subsequent interventions included additional diagnostic testing, drug administration, and transfer to a higher acuity of care, rapid response team intervention or code 99.
Results: 3 months of TECG monitoring yielded a total of 280 telemetric events and 62 (22.1%) required intervention. The most common arrhythmias requiring intervention were atrial fibrillation (N=27), ventricular tachycardia (N =7) and supra ventricular tachycardia (N=5) (figure 1). One case of Torsade de Pointes was detected. The most common interventions were drug administration (N=26), additional diagnostic testing ordered (N=36) and code 99, transfer to higher acuity of care or rapid response team intervention (N=11).
Conclusion: Our results suggest that central telemetry monitoring in a modern hospital results in a substantial number of interventions in response to telemetry findings. We intend to use these data in further studies assessing the utility of central telemetry compared to local monitoring techniques.
