OBJECTIVES: Regular follow-up (FU) of CIED patients is mandatory to monitor device functionality and disease status. Demand for this highly specialised service increases continuously. However, most calendar based visits do not need further action and could safely be replaced by remote monitoring. This model aims 1) to quantify hospital workload associated with calendar based FU between 2011 and 2015, and 2) to identify opportunity costs if monitoring services would be performed remotely. METHODS: The estimated number of prevalent CIED patients in Germany was combined with recently published data on healthcare personnel resource burden related to FU. Opportunity costs were identified considering 2011 DRG payments for frequent cardiology procedures. RESULTS: Assuming in-office FU twice annually for pacemaker patients, and four times annually for implantable cardioverter defibrillator or cardiac resynchronisation therapy patients, hospitals will have to provide about 2.23 mio FU services in 2015, to about 856,000 patients. These services will bind about 411,000 physician hours, 392,000 nurse hours and 280,000 technician hours, at total costs of EURO 44.8 mio to hospitals. Using remote monitoring to replace all but one in-office FU visit per year could free up to 126,700 physician hours (2015). In theory, this physician time would allow for about 50’600 bypass surgeries (worth EURO 596 mio), or 84,400 dual-chamber pacemaker implantations (EURO 434 mio), or 63,300 dual chamber ICD implantations (EURO 1.1 billion). Possible cost overestimation due to not considering unscheduled FU visits is explored in scenario analyses. CONCLUSIONS: The ability of BIOTRONIK Home Monitoring to safely replace in-office FU visits has been proven in clinical trials. While continuously monitoring all patients, it is possible to identify patients in need to attend in clinic FU in person. Remote monitoring technologies can support hospitals with focussing their available staff and room capacities and optimise operative income while providing patient care at potentially improved outcomes.
