A Patient-Centered Intervention Reduces Disparities in Remote Monitoring in Patients With Implanted Cardiac Devices

BACKGROUND

Remote monitoring (RM) is recommended for patients with cardiovascular implantable electronic devices, yet many individuals, especially those living in underserved communities, fail to receive this guideline-directed care. Multilevel interventions that target patient and clinic-level barriers to RM care may be beneficial.

OBJECTIVES

This study sought to evaluate a remotely delivered, patient-centered intervention to improve RM activation and adherence and reduce disparities in RM care.

METHODS

The intervention provides home delivery of remote monitor, phone-based education, monitor setup, and facilitation of first transmission. A retrospective cohort analysis was performed using RM data from 190,643 patients (71.6 ± 12.7 years of age, 40.5% female) implanted with a pacemaker or defibrillator at 4,195 U.S. clinics between October 2015 and October 2019. Outcomes included RM activation (12 weeks and 1-year postimplantation) and adherence to clinic-scheduled transmissions. Patients receiving a cardiovascular implantable electronic deviceimplant 0 to 730 days before (control group, n = 95,861) and after (intervention group, n = 94,782) intervention launch were compared using logistic regression and generalized estimating equations. Multivariable models included patient, clinic, and neighborhood socioeconomic characteristics.

RESULTS

The odds of achieving guideline-recommended activation were significantly higher in the intervention group at 12 weeks (OR: 2.99; 76.7% vs 60.9%; P < 0.001) and 1 year (OR: 3.05; 88.2% vs 79.3%; P < 0.001). Adherence to scheduled transmissions was also higher in the intervention group compared with the control group (OR: 2.18; 89.1% vs 81.9%; P < 0.001). Preintervention disparities in RM activation and adherence were reduced in underserved groups following the intervention.

CONCLUSIONS

A remotely delivered patient-centered intervention was associated with earlier activation and improved adherence to RM while reducing disparities in RM care.

Informational Postcards Increase Engagement with Remote Monitoring Among Veterans with Pacemakers and Implantable Cardioverter-Defibrillators: a Stepped-Wedge Randomized Controlled Trial

BACKGROUND

Remote monitoring (RM) of pacemakers and implantable cardioverter-defibrillators (ICDs) reduces morbidity and mortality. However, many patients are not adherent to RM.

OBJECTIVE

To test the effect of informational postcards on RM adherence.

DESIGN/PATIENTS

Stepped-wedge randomized controlled trial among Veterans with pacemakers and ICDs.

INTERVENTION

In wave 1, Veterans who had sent at least 1 transmission within the past 2 years but had become non-adherent were randomly assigned to receive a postcard or no postcard. Those receiving postcards were randomized to 1 of 2 messages: (1) a"warning" postcard describing risks of non-adherence or (2) an "encouraging" postcard describing benefits of adherence. In wave 2, Veterans who had either not received a postcard in wave 1 or had since become non-adherent were mailed a postcard (again, randomized to 1 of 2 messages). Patients who did not send an RM transmission within 1 month were mailed a second, identical postcard.

MAIN MEASURES

Transmission within 70 days.

KEY RESULTS

Overall, 6351 Veterans were included. In waves 1 and 2, postcards were mailed to 5657 Veterans (2821 "warning" messages and 2836 "encouraging" messages). Wave 1 included 2178 Veterans as controls (i.e., not mailed a postcard), some of whom received a postcard in wave 2 if they remained non-adherent. In wave 2, 3473 postcards were sent. Of the 5657 patients mailed a postcard, 2756 (48.7%) sent an RM transmission within 70 days, compared to 530 (24.3%) of 2178 controls (absolute difference 24.4%, 95% confidence interval [CI] 22.2%, 26.6%). Of those who sent a transmission, 71.8% did so after the first postcard. Transmission rates at 70 days did not significantly differ between "warning" and "encouraging" messages (odds ratio 1.04, 95% CI 0.92, 1.18).

CONCLUSIONS

Informational postcards led to a 24.4% absolute increase in adherence at 70 days among Veterans with pacemakers and ICDs who were non-adherent to RM.

HeartLogic™: real-world data-efficiency, resource consumption, and workflow optimization

Heart failure (HF) is a major and still growing medical problem and is characterized by episodes of acute decompensation that are associated with a negative prognosis and a significant burden on the patients, doctors, and healthcare resources. Early detection of incipient HF may allow outpatient treatment before patients severely decompensate, thus reducing HF hospitalizations and related costs. The HeartLogic™ algorithm is an automatic, remotely managed system combining data directly related to HF pathophysiology into a single score, the HeartLogic™ index. This index proved to be effective in predicting the risk of incipient HF decompensation, allowing to redistribute resources from low-risk to high-risk patients in a timely and cost-saving manner. The alert-based remote management system seems more efficient than the one based on scheduled remote transmission in terms of caregivers' workload and alert detection timing. The widespread application of the HeartLogic™ algorithm requires the resolution of logistical and financial issues and the adoption of a pre-defined, functional workflow. In this paper, we reviewed general aspects of remote monitoring in HF patients, the functioning and pathophysiological basis of the HeartLogic index, its efficiency in the management of HF patients, and the economic effects and the organizational revolution associated with its use.
