The adoption of remote monitoring (RM) is especially relevant for patients with implantable cardiac devices due to their high risk of hospitalization and the need for frequent outpatient visits. Though RM can help with early detection of cardiac episodes, it may also increase the number of tasks healthcare providers engage in to monitor patients' health. The adoption of RM may increase healthcare providers' workloads, potentially impacting the quality of care and increasing the risk of clinician-provider burnout. Little is known about the link between RM adoption and changes in healthcare providers' workloads. Using data from a non-randomized clinical trial conducted in 2021-2022 at a University Hospital in Korea, we examined the relationship between RM adoption and changes in patient time savings and healthcare providers' workloads. The clinical trial included patients with a cardiac implantable electronic device compatible with the Biotronik Home Monitoring System. For patients, RM was associated with a 41-minute decrease in total visit duration, attributed to reductions in both wait time (37 minutes; P<0.001) and total examination time (3.7 minutes; P=0.137). For healthcare providers, RM was linked to an increase in overall workload by 107.9 minutes per patient. The increase was primarily due to managing RM alerts (91.8 minutes) and preparing monthly patient reports (19.9 minutes). Our findings suggest that RM was associated with a decrease of 1540 KRW (44%) in average cost of care per minute. RM is associated with time-saving patient benefits and increased healthcare providers' workloads. Even though this was a single-center study with a small number of patients, our research highlights the importance of carefully examining changes in healthcare staff workloads linked to the adoption of RM within the national health insurance system.
