Impact of remote monitoring on clinical events and associated health care utilization: A nationwide assessment.
BACKGROUND: Remote monitoring (RM) of cardiac implantable electronic devices (CIEDs) improves patient survival. However, whether RM reduces health care utilization is unknown. OBJECTIVE: The purpose of this study was to determine whether RM was associated with reduced hospitalization and costs in clinical practice. METHODS: We conducted a nationwide cohort study using the Truven Health Analytics MarketScan database. Patients implanted with a CIED between March 31, 2009, and April 1, 2012, were included. All-cause hospitalization events were compared between those using RM and those not using RM by using Cox proportional hazards methods with Andersen-Gill extension and propensity scoring. We also compared health care costs (payments >30 days after CIED implantation). RESULTS: Overall, there were 92,566 patients (mean age 72 ± 13 years; 58,140 [63%] men) with a mean follow-up of 19 ± 12 months, including 54,520 (59%) pacemaker, 27,816 (30%) implantable cardioverter-defibrillator, and 10,230 (11%) cardiac resynchronization therapy patients. Only 37% of patients (34,259) used RM. Patients with RM had Charlson Comorbidity Index values similar to those not using RM but had lower adjusted risk of all-cause hospitalization (adjusted hazard ratio 0.82; 95% confidence interval 0.80-0.84; P < .001) and shorter mean length of hospitalization (5.3 days vs 8.1 days; P < .001) during follow-up. RM was associated with a 30% reduction in hospitalization costs ($8720 mean cost per patient-year vs $12,423 mean cost per patient-year). For every 100,000 patient-years of follow-up, RM was associated with 9810 fewer hospitalizations, 119,000 fewer days in hospital, and $370,270,000 lower hospital payments. CONCLUSION: RM is associated with reductions in hospitalization and health care utilization. Since only about a third of patients with CIEDs routinely use RM, this represents a major opportunity for quality improvement.
