Impact of Remote Monitoring on Clinical Outcomes

Abstract

Follow-up of patients with cardiac implantable electronic devices is challenging due to both their increasing volume and technical complexity coupled to increasing clinical complexity of recipient patients. Remote monitoring (RM) offers an opportunity to resolve some of these difficulties by improving clinic efficiencies and providing a mechanism for device monitoring and patient management. Several recent randomized clinical trials and registries have demonstrated that RM may reduce in-hospital visit numbers, time required for patient follow-up, physician and nurse time, and hospital and social costs. Furthermore, patient retention and adherence to follow-up schedule are significantly improved by RM. Continuous wireless monitoring of data stored in the device memory with automatic alerts allows early detection of device malfunctions and of events, such as atrial fibrillation, ventricular arrhythmias, and heart failure suitable for clinical intervention. Early reaction may improve patient outcome. RM is easy to use and patients showed a high level of acceptance and satisfaction. Implementing RM in daily practice may require changes in clinic workflow. New organizational models promote significant efficiencies regarding physician and nursing time. Data management techniques are under development. Despite these demonstrable advantages of RM, adoption still remains modest, even in health care systems incentivized to use this follow-up method.
