Remote Monitoring and Outcomes in Pacemaker and Defibrillator Patients: Big Data Saving Lives?

Remote Monitoring of Cardiovascular Implantable Electronic Devices in Canada: Survey of Patients and Device Health Care Professionals

Background

Remote monitoring is used to supplement in-clinic follow-up for patients with cardiac implantable electronic devices (CIEDs) every 6-12 months. There is a need to optimize remote management for CIEDs because of the consistent increases in CIED implants over the past decade. The objective of this study was to investigate real and perceived barriers to the use of remote patient management strategies in Canada and to better understand how remote models of care can be optimized.

Methods

We surveyed 512 CIED patients and practitioners in 22 device clinics in Canada.

Results

Device clinic surveys highlighted significant variation and inconsistency in follow-up care for in-clinic and remote visits across and within clinics. This survey showed that funding policies and management of additional workflow are barriers to optimal use and uptake. Despite this, device clinics perceive remote follow-up as a valuable resource and an efficient way to manage patient follow-up. Patients were broadly satisfied with their CIED follow-up care but identified barriers related to coordination of care, visit logistics, and information needs. Views varied as a function of clinical or sociodemographic characteristics. Most patients (n = 228; 91%) expressed a desire to receive a phone call from their device clinic after a remote transmission has been received.

Conclusions

Lack of a unified, guideline-supported approach to follow-up after CIED implant, and discrepant funding policies across jurisdictions, are significant barriers to the use of remote patient management strategies in Canada. Efforts to increase or expand use of remote follow-up must recognize these barriers and the needs of specific subgroups of patients.

Long-term cost-utility analysis of remote monitoring of older patients with pacemakers: the PONIENTE study

Background

Cost-effectiveness studies on pacemakers have increased in the last years. However the number of long-term cost-utility studies is limited. The objective of this study was to perform a cost-utility analysis comparing remote monitoring (RM) versus conventional monitoring (CM) in hospital of older patients with pacemakers, 5 years after implant.

Methods

Under a controlled, not randomized, nor masked clinical trial, 83 patients with pacemakers were initially selected. After five years of follow-up, a total of 55 patients (CM = 34; RM = 21) completed the study. A cost-utility analysis of RM in terms of costs per gained quality-adjusted life years (QALYs) was conducted. The costs from the Public Health System (PHS) as well as patients and their relatives were taken into account for the study. The robustness of the results was verified by the probabilistic analyses through Monte-Carlo simulations.

Results

After a five-year follow-up period, total costs were lower in the RM group by 23.02% than in the CM group (€274.52 versus €356.62; p = 0.033) because of a cost saving from patients’ perspective (€59.05 versus €102.98; p = 0.002). However, the reduction of in-hospital visits derived from RM exhibited insignificant impact on the costs from the PHS perspective, with a cost saving of 15.04% (€215.48 vs. €253.64; p = 0.144). Costs/QALYs obtained by the RM group were higher as compared to the CM group, although there were no significant differences. The incremental cost-effectiveness ratio of CM in comparison to RM became positive (€301.16).

Conclusions

This study confirms RM of older patients with pacemakers appears still as a cost-utility alternative to CM in hospital after 5 years of follow-up.

Effectiveness and Safety in Remote Monitoring of Patients with Pacemakers Five Years after an Implant: The Poniente Study

Health-related quality of life (HRQoL) and functional capacity values immediately after pacemaker (PM) implantation have been well established; however, not much has been known about its long-term effects. The present study compared the long-term effectiveness and safety of remote monitoring plus a clinic visit versus clinic visits alone during follow-up of adults implanted with PMs. This study was a single-centre, controlled, non-randomised, non-blinded clinical trial. Data were collected pre-implantation and after 60 months. The patients in the PONIENTE study were assigned to two different groups: remote monitoring (RM) and conventional monitoring (CM). The EuroQol-5D (EQ-5D) questionnaire was used to assess HRQoL and Duke Activity Status Index was used for the functional capacity. After five years, 55 patients completed the study (RM = 21; CM = 34). EuroQol-5D and functional capacity values were improved; however, significant differences were observed only in the EQ5D visual analogue scale (p < 0.001). Remote monitoring was equally feasible, reliable, safe, and clinically useful as CM. The frequencies of rehospitalisations and emergency visits did not differ between the groups. RM was found to be safe and effective in early detection and treatment of medical- and device-related events and in reducing hospital visits. Improved HRQoL was described not only immediately after PM implantation but also extended over a long time.

Remote monitoring of implantable cardiac devices: current state and future directions

PURPOSE OF REVIEW

Recent evidence has demonstrated substantial benefits associated with remote monitoring of cardiac implantable electronic devices (CIEDs), and treatment guidelines have endorsed the use of remote monitoring. Familiarity with the features of remote monitoring systems and the data supporting its use are vital for physicians' care for patients with CEIDs.

RECENT FINDINGS

Remote monitoring remains underutilized, but its use is expanding including in new practice settings including emergency departments. Patient experience and outcomes are positive, with earlier detection of clinical events such as atrial fibrillation, reductions in inappropriate implantable cardioverter-defibrillator (ICD) shocks and potentially a decrease in mortality with frequent remote monitoring utilizaiton. Rates of hospitalization are reduced among remote monitoring users, and the replacement of outpatient follow-up visits with remote monitoring transmissions has been shown to be well tolerated. In addition, health resource utilization is lower and remote monitoring has been associated with considerable cost savings. A dose relationship exists between use of remote monitoring and patient outcomes, and those with early and high transmission rates have superior outcomes.

SUMMARY

Remote monitoring provides clinicians with the ability to provide comprehensive follow-up care for patients with CIEDs. Patient outcomes are improved, and resource utilization is decreased with appropriate use of remote monitoring. Future efforts must focus on improving the utilization and efficiency of remote monitoring.

International Mobile-Health Intervention on Physical Activity, Sitting, and Weight: The Stepathlon Cardiovascular Health Study

BACKGROUND

Although proof-of-concept for mobile health (mHealth) life-style programs targeting physical inactivity and overweight/obesity has been established in randomized trials, the feasibility and effect of a globally distributed, large-scale, mass-participation mHealth implementation has not been investigated.

OBJECTIVES

The purpose of this study was to determine the effect of Stepathlon, an international, low-cost, mass-participation mHealth intervention, on physical activity, sitting, and weight.

METHODS

We prospectively collected cohort data from participants completing Stepathlon, an annual 100-day global event in 2012, 2013, and 2014. Participants were organized in worksite-based teams, issued pedometers, and encouraged to increase daily steps and physical activity as part of the team-based race. The program was conducted via an interactive multiplatform application available on mobile devices and the Internet. Analysis was performed according to a pre-specified plan.

RESULTS

A total of 69,219 subjects participated (481 employers, 1,481 cities, 64 countries, all populated continents, age 36 ± 9 years, 23.9% female, 8.0% high-income countries, and 92.0% lower-middle income countries). After Stepathlon completion, participants recorded improved step count (+3,519 steps/day; 95% confidence interval [CI]: 3,484 to 3,553 steps/day; p < 0.0001), exercise days (+0.89 days; 95% CI: 0.87 to 0.92 days; p < 0.0001), sitting duration (-0.74 h; 95% CI: -0.78 to -0.71 h; p < 0.0001) and weight (-1.45 kg; 95% CI: -1.53 to -1.38 kg; p < 0.0001). Improvements occurred in women and men, in all geographic regions, and in both high and lower-middle income countries, and the results were reproduced in 2012, 2013, and 2014 cohorts. Predictors of weight loss included step increase, sitting duration decrease, and increase in exercise days (all p < 0.0001).

CONCLUSIONS

Distributed mHealth implementation of a low-cost life-style intervention is associated with short-term, reproducible, large-scale improvements in physical activity, sitting, and weight. (Effect of the Stepathlon Pedometer Program on Physical Activity, Weight and Well-Being; ACTRN12615001310550).
