Abstract 12221: Work Improvement With Novel Remote Monitoring System (Impella Connect) in Clinical Engineer Involving Acute Mechanical Circulatory Support
Circulation(2022)
Abstract
Introduction: Recent innovations in mechanical circulatory support (MCS) enable physicians to deal with challenging cases with cardiogenic shock. As the number of MCS has increased, the excessive workload of clinical engineers (CEs) who manage MCS has become a serious problem. To overcome such situation, we introduced innovative remote monitoring system of circulatory assist pump catheters (Impella) called Impella Connect (IC) from 2020, which allows medical staff to monitor driving status and alarms of Impella in their mobile devices. Here we reported our experience of IC and the safety and efficacy of our protocol using IC for management of Impella. Methods: We identified 63 Impella cases for cardiogenic shock from 2018 to 2021 in our institution. We utilized Impella 2.5/CP in 53 cases and Impella 5.0 in 10 cases depending on their hemodynamic condition. Before introducing IC (nIC period: n=17), CEs were responsible for Impella management in all time periods and needed to work overtime to manage devices in night time. However, after introducing IC (IC periods: n=46), CEs were responsible only in daytime and non-MCS expert medical stuff were responsible in night time supporting by CEs’ remote monitoring with IC. We retrospectively evaluated the safety and efficacy of our management using IC. Results: Impella insertion was performed emergently in all cases and the 34 cases (53.9 %) were inserted in night time. Average support time was 6.5±0.6 days (nIC 7.7 vs. 6.0 days). We encountered 13 device trouble in nIC periods (purge system in 8, pressure sensor in 4 and pump malfunction in 1) and 14 in IC periods (purge system in 9, pressure sensor in 3 and pump malfunction in 2). Device trouble requiring intervention was not significantly different in both periods (nIC/IC 10 vs. 11 cases, p=0.85) and adverse event related to delayed or inappropriate response was not observed in both periods. The average of overtime working hours of CEs per month was significantly decreasing in IC periods (53.1±16.8 vs. 8.6±2.6 hours per month, p<0.05). Conclusions: Our Impella management using novel remote monitoring system with Impella Connect was safe with no adverse events and effective to reduce overtime work of CEs, which resulted in work improvement of medical stuff involving MCS.
