Strategic reprogramming of implantable cardiac monitors reduces the false-positive remote alert burden in a nurse-led service.

AIMS: Implantable cardiac monitors (ICMs) can generate false-positive (FP) alerts. Although these devices have an extended programmability, there are no recommendations on their optimization to reduce not-relevant activations.We tested a strategic programming optimization guide based on the type of FP and investigated the safety and feasibility of the nurse-led insertion of ICMs with a long-sensing vector. METHODS AND RESULTS: Consecutive patients implanted by trained nurses with long-sensing vector ICM were enrolled in a 1-month observational stage (Phase A). Patients who had ≥10 FP episodes underwent ICM reprogramming based on the predefined guide and were followed for an additional month (Phase B). A total of 78 patients had successful ICM insertion by nurses with a mean R wave amplitude of 0.96 ± 0.43 mV and an 86% P wave visibility. Only one patient reported a significant device-related issue, and nurse-delivered ICM was generally well accepted by the patients. During Phase A, 11 patients (14%) generated most of FP (3,627/3,849; 94%) and underwent ICM reprogramming. In the following month (Phase B), five patients (45%) were free from FP and six (55%) transmitted 57 FP alerts (98% reduction compared with Phase A). The median number of FP per patient was significantly reduced after reprogramming [195 (interquartile range, 50-311) vs. one (0-10), P = 0.0002]. CONCLUSION: A strategic reprogramming of ICM in those patients with a high FP alert burden reduces the volume of erroneous activations with potential benefits for the remote monitoring service. No concerns were raised regarding nurse-led insertion of ICMs with a long-sensing vector.

Implementation of remote follow-up of cardiac implantable electronic devices in clinical practice: organizational implications and resource consumption.

AIMS: Current guidelines recommend remote follow-up for all patients with cardiac implantable electronic devices. However, the introduction of a remote follow-up service requires specifically dedicated organization. We evaluated the impact of adopting remote follow-up on the organization of a clinic and we measured healthcare resource utilization. METHODS: In 2016, we started the implementation of the remote follow-up service. Each patient was assigned to an experienced nurse and a doctor in charge with preestablished tasks and responsibilities. During 2016 and 2017, all patients on active follow-up at our center were included in the service; since 2018, the service has been fully operational for all patients following postimplantation hospital discharge. RESULTS: As of December 2018, 2024 patients were on active follow-up at the center. Of these, 93% of patients were remotely monitored according to the established protocol. The transmission rates were: 5.3/patient-year for pacemakers, 6.0/patient-year for defibrillators, and 14.1/patient-year for loop recorders. Only 21% of transmissions were submitted to the physician for further clinical evaluation, and 3% of transmissions necessitated an unplanned in-hospital visit for further assessment. Clinical events of any type were detected in 39% of transmissions. Overall, the nurses' total workload was 3596 h per year, that is, 1.95 full-time equivalent, which resulted in 1038 patients/nurse. The total workload for physicians was 526 h per year, that is, 0.29 full-time equivalent. After 1 year on follow-up, most patients judged the service positively and expressed their preference for the new follow-up approach. CONCLUSION: A remote follow-up service can be implemented and efficiently managed by nursing staff with minimal physician support. Patients are followed up with greater continuity and seem to appreciate the service.
