Large Controlled Observational Study on Remote Monitoring of Pacemakers and Implantable Cardiac Defibrillators: A Clinical, Economic, and Organizational Evaluation

Investigating the Cost-Effectiveness of Telemonitoring Patients With Cardiac Implantable Electronic Devices: Systematic Review

BACKGROUND

Telemonitoring patients with cardiac implantable electronic devices (CIEDs) can improve their care management. However, the results of cost-effectiveness studies are heterogeneous. Therefore, it is still a matter of debate whether telemonitoring is worth the investment.

OBJECTIVE

This systematic review aims to investigate the cost-effectiveness of telemonitoring patients with CIEDs, focusing on its key drivers, and the impact of the varying perspectives.

METHODS

A systematic review was performed in PubMed, Web of Science, Embase, and EconLit. The search was completed on July 7, 2022. Studies were included if they fulfilled the following criteria: patients had a CIED, comparison with standard care, and inclusion of health economic evaluations (eg, cost-effectiveness analyses and cost-utility analyses). Only complete and peer-reviewed studies were included, and no year limits were applied. The exclusion criteria included studies with partial economic evaluations, systematic reviews or reports, and studies without standard care as a control group. Besides general study characteristics, the following outcome measures were extracted: impact on total cost or income, cost or income drivers, cost or income drivers per patient, cost or income drivers as a percentage of the total cost impact, incremental cost-effectiveness ratios, or cost-utility ratios. Quality was assessed using the Consensus Health Economic Criteria checklist.

RESULTS

Overall, 15 cost-effectiveness analyses were included. All studies were performed in Western countries, mainly Europe, and had primarily a male participant population. Of the 15 studies, 3 (20%) calculated the incremental cost-effectiveness ratio, 1 (7%) the cost-utility ratio, and 11 (73%) the health and cost impact of telemonitoring. In total, 73% (11/15) of the studies indicated that telemonitoring of patients with implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy ICDs was cost-effective and cost-saving, both from a health care and patient perspective. Cost-effectiveness results for telemonitoring of patients with pacemakers were inconclusive. The key drivers for cost reduction from a health care perspective were hospitalizations and scheduled in-office visits. Hospitalization costs were reduced by up to US $912 per patient per year. Scheduled in-office visits included up to 61% of the total cost reduction. Key drivers for cost reduction from a patient perspective were loss of income, cost for scheduled in-office visits and transport. Finally, of the 15 studies, 8 (52%) reported improved quality of life, with statistically significance in only 1 (13%) study (P=.03).

CONCLUSIONS

From a health care and patient perspective, telemonitoring of patients with an ICD or a cardiac resynchronization therapy ICD is a cost-effective and cost-saving alternative to standard care. Inconclusive results were found for patients with pacemakers. However, telemonitoring can lead to a decrease in providers' income, mainly due to a lack of reimbursement. Introducing appropriate reimbursement could make telemonitoring sustainable for providers while still being cost-effective from a health care payer perspective.

Telemedicine and the assessment of clinician time: a scoping review

OBJECTIVES

Telemedicine may improve healthcare access and efficiency if it demands less clinician time than usual care. We sought to describe the degree to which telemedicine trials assess the effect of telemedicine on clinicians' time and to discuss how including the time needed to treat (TNT) in health technology assessment (HTA) could affect the design of telemedicine services and studies.

METHODS

We conducted a scoping review by searching clinicaltrials.gov using the search term "telemedicine" and limiting results to randomized trials or observational studies registered between January 2012 and October 2023. We then reviewed trial registration data to determine if any of the outcomes assessed in the trials measured effect on clinicians' time.

RESULTS

We found 113 studies and of these 78 studies of telemedicine met the inclusion criteria and were included. Nine (12 percent) of the 78 studies had some measure of clinician time as a primary outcome, and 11 (14 percent) as a secondary outcome. Four studies compared direct measures of TNT with telemedicine versus usual care, but no statistically significant difference was found. Of the sixteen studies including indirect measures of clinician time, thirteen found no significant effects, two found a statistically significant reduction, and one found a statistically significant increase.

CONCLUSIONS

This scoping review found that clinician time is not commonly measured in studies of telemedicine interventions. Attention to telemedicine's TNT in clinical studies and HTAs of telemedicine in practice may bring attention to the organization of clinical workflows and increase the value of telemedicine.

Clinician use of data elements from cardiovascular implantable electronic devices in clinical practice

Background

Cardiovascular implantable electronic devices (CIEDs) capture an abundance of data for clinicians to review and integrate into the clinical decision-making process. The multitude of data from different device types and vendors presents challenges for viewing and using the data in clinical practice. Efforts are needed to improve CIED reports by focusing on key data elements used by clinicians.

Objective

The purpose of this study was to uncover the extent to which clinicians use the specific types of data elements from CIED reports in clinical practice and explore clinicians' perceptions of CIED reports.

Methods

A brief, web-based, cross-sectional survey study was deployed using snowball sampling from March 2020 through September 2020 to clinicians who are involved in the care of patients with CIEDs.

Results

Among 317 clinicians, the majority specialized in electrophysiology (EP) (80.1%), were from North America (88.6%), and were white (82.2%). Over half (55.3%) were physicians. Arrhythmia episodes and ventricular therapies rated the highest among 15 categories of data presented, and nocturnal or resting heart rate and heart rate variability were rated the lowest. As anticipated, clinicians specializing in EP reported using the data significantly more than other specialties across nearly all categories. A subset of respondents offered general comments describing preferences and challenges related to reviewing reports.

Conclusion

CIED reports contain an abundance of information that is important to clinicians; however, some data are used more frequently than others, and reports could be streamlined for users to improve access to key information and facilitate more efficient clinical decision making.

Wearable Devices for Remote Monitoring of Heart Rate and Heart Rate Variability-What We Know and What Is Coming

Heart rate at rest and exercise may predict cardiovascular risk. Heart rate variability is a measure of variation in time between each heartbeat, representing the balance between the parasympathetic and sympathetic nervous system and may predict adverse cardiovascular events. With advances in technology and increasing commercial interest, the scope of remote monitoring health systems has expanded. In this review, we discuss the concepts behind cardiac signal generation and recording, wearable devices, pros and cons focusing on accuracy, ease of application of commercial and medical grade diagnostic devices, which showed promising results in terms of reliability and value. Incorporation of artificial intelligence and cloud based remote monitoring have been evolving to facilitate timely data processing, improve patient convenience and ensure data security.

Role of telemedicine in the management of oral anticoagulation in atrial fibrillation: a practical clinical approach

Compared with face-to-face consultations, telemedicine has many advantages, including more efficient use of healthcare resources, partial relief of the burden of care, reduced exposure to COVID-19, treatment adjustment, organization of more efficient healthcare circuits and patient empowerment. Ensuring optimal anticoagulation in atrial fibrillation patients is mandatory if we want to reduce the thromboembolic risk. Of note, telemedicine is an excellent option for the long-term management of atrial fibrillation patients. Moreover, direct oral anticoagulants may provide an added value in telemedicine (versus vitamin K antagonists), as it is not necessary to monitor anticoagulant effect or make continuous dosage adjustments. In this multidisciplinary consensus document, the role of telemedicine in anticoagulation of this population is discussed and practical recommendations are provided.

How to Pay for Telemedicine: A Comparison of Ten Health Systems

Telemedicine has the opportunity to improve clinical effectiveness, health care access, cost-savings, and patient care. However, payment systems may form important obstacles to optimally use telemedicine and enable its opportunities. Little is known about payment systems for telemedicine. Therefore, this research aims to increase knowledge on paying for telemedicine by comparing payment systems for telemedicine and identifying similarities and differences. Based on the countries' official physician fee schedules, listing all reimbursed medical services performed by physicians, a comparative analysis of telemedicine payment systems in ten countries was conducted. Findings show that many countries lacked tele-expertise and telemonitoring payment, with the exception for some specific payments such as for telemonitoring in patients with cardiac implantable electronic devices. Moreover, a wide variety of benefit specifications were implemented in all countries to specify which type of clinician contact should be used (remote versus physical) in which circumstances. Payment parity between video and in-person visits was established only in a few countries. Furthermore, fee-for-service was the dominant payment system, although two countries used a capitation-based or hybrid system. The results imply several potential payment challenges when implementing telemedicine: complex benefit specifications, payment parity discussions, and risk of overconsumption due to the dominant fee-for-service system. These challenges appear to be less present in capitation-based or hybrid systems. However, the latter needs to be further explored to harness the full potential of telemedicine.

Remote Monitoring of CIEDs-For Both Safety, Economy and Convenience?

Cardiac implantable electronic devices such as pacemakers and defibrillators are increasingly monitored by systems transmitting information directly from the patient to the hospital. This may increase safety and patient satisfaction and also under certain circumstances represent an economic advantage. The review summarizes some of the recent research in the field of remote monitoring of cardiac devices.

Organizational Models for Cardiac Implantable Electronic Device Remote Monitoring: Current and Future Directions

This review provides an overview of the literature on the organization, staffing, and structure of remote monitoring (RM) clinics, primarily from countries in Western Europe and United States, as well as the challenges, considerations, and future directions for RM clinic models of care. Using a current case example of an RM clinic in the Midwestern United States, this document provides key information from the viewpoint of a clinic undergoing a shift in workflow. Finally, this review distills key considerations for RM management for electrophysiology clinics, vendors and industry, and policy makers.

Patient and Provider Perspectives on Remote Monitoring of Pacemakers and Implantable Cardioverter-Defibrillators

The use of remote monitoring technology for cardiovascular electronic implantable devices has grown significantly in recent decades, yet several key questions remain about its integration into clinical care. We performed semi-structured interviews of patients, clinicians, and device clinic technicians involved in clinical remote monitoring of cardiovascular implantable devices at our institution. Twenty-eight interviews comprised of 15 patients and 13 clinicians were conducted from October 2019 through February 2020. Interview transcripts were analyzed using a mixed inductive and deductive approach. Perspectives among clinicians and patients varied regarding familiarity, educational experiences, and preferences regarding how remote monitoring data are handled. Three key domains emerged including knowledge and understanding, managing alerts, and cost transparency. Within these domains, key findings includedvery limited understanding of how remote monitoring functions and how alerts in particular are handled. These knowledge deficits (both patients and providers) appeared to arise in part from different equipment and platforms among manufacturers, the complexity of the technology, and lack of formalized education in remote monitoring. However, interviewees expressed generally high levels of trust in the technology and care systems supporting remote monitoring. Few respondents described concerns around cybersecurity, but patients in particular did raise concerns about cost transparency and frequent billing. In conclusion, conflicting perceptions around remote monitoring persist and indicate important knowledge gaps despite high trust in the care pathway. This qualitative analysis offers insight into patient and clinician understanding of and attitudes toward remote monitoring, and may guide future efforts to improve education and patient-centeredness of remote monitoring.

Clinic Time Required for Remote and In-person Management of Cardiac Device Patients: Time and Motion Workflow Evaluation

BACKGROUND

The number of patients with cardiac implantable electronic devices (CIEDs) is growing, creating substantial workload for device clinics.

OBJECTIVE

This study aimed to characterize the workflow and quantify clinic staff time requirements to manage CIED patients.

METHODS

A time and motion workflow evaluation was performed in 11 US and European CIED clinics. Workflow tasks were repeatedly timed during one business week of observation at each clinic. Observations were inclusive of all device models/manufacturers present. Mean cumulative staff time required to review a Remote device transmission and for an In-person clinic visit were calculated, including all necessary clinical and administrative tasks. Annual staff time for follow-up of 1 CIED patient was modeled using CIED transmission volumes, clinical guidelines, and published literature.

RESULTS

A total of 276 in-person clinic visits and 2,173 remote monitoring activities were observed. Mean staff time required per remote transmission ranged from 9.4-13.5 minutes for therapeutic devices (pacemaker, ICD, CRT) and 11.3-12.9 mins for diagnostic devices (insertable cardiac monitors (ICMs)). Mean staff time per in-person visit ranged from 37.8-51.0 mins and 39.9-45.8 mins, for therapeutic devices and ICMs respectively. Including all remote and in-person follow-ups, the estimated annual time to manage one CIED patient ranged from 1.6-2.4 hours for therapeutic devices and 7.7-9.3 hours for ICMs.

CONCLUSIONS

CIED patient management workflow is complex and requires significant staff time. Understanding process steps and time requirements informs implementation of efficiency improvements, including remote solutions. Future research should examine the heterogeneity in patient management processes to identify the most efficient workflows.

CLINICALTRIAL

Remote monitoring of implantable defibrillators is associated with fewer inappropriate shocks and reduced time to medical assessment in a remote and rural area

BACKGROUND

Implantable cardioverter defibrillators (ICDs) and cardiac resynchronisation therapy with defibrillators (CRT-D) reduce mortality in certain cardiac patient populations. However, inappropriate shocks pose a problem, having both adverse physical and psychological effects on the patient. The advances in device technology now allow remote monitoring (RM) of devices to replace clinic follow up appointments. This allows real time data to be analysed and actioned and this may improve patient care.

AIM

To determine if RM in patients with an ICD is associated with fewer inappropriate shocks and reduced time to medical assessment.

METHODS

This was a single centre, retrospective observational study, involving 156 patients implanted with an ICD or CRT-D, followed up for 2 years post implant. Both appropriate and inappropriate shocks were recorded along with cause for inappropriate shocks and time to medical assessment.

RESULTS

RM was associated with fewer inappropriate shocks (13.6% clinic vs 3.9% RM; P = 0.030) and a reduced time to medical assessment (15.1 ± 6.8 vs 1.0 ± 0.0 d; P < 0.001).

CONCLUSION

RM in patients with an ICD is associated with improved patient outcomes.

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.

Trends in utilization and spending on remote monitoring of pacemakers and implantable cardioverter-defibrillators among Medicare beneficiaries

BACKGROUND

National trends and costs associated with remote and in-office interrogations of pacemakers and implantable cardioverter-defibrillators (ICDs) have not been previously described.

OBJECTIVE

The purpose of this study was to evaluate utilization and Medicare spending for remote monitoring and in-office interrogations for pacemakers and ICDs.

METHODS

We performed a retrospective cohort study of claims and spending for remote and in-office interrogations of pacemakers and ICDs for Medicare fee-for-service beneficiaries from 2012 to 2015. Aggregate and per-beneficiary claims and spending were calculated for each device type.

RESULTS

Among all patients, 41.9% were female and the mean age was 78.3 years. From 2012 to 2015, remote monitoring utilization increased sharply. Aggregate professional remote monitoring claims for pacemakers increased by 61.3% and for ICDs by 5.6%, with an increase in technical claims (combined for pacemakers and ICDs) of 32.8%. Spending on all remote and in-office interrogations for these devices totaled $160 million per year, with remote costs increasing nearly 25% from $45.4 million in 2012 to $56.7 million in 2015. At the beneficiary level, remote interrogations increased for pacemakers from 0.6 to 0.9 per year, and for ICDs from 1.3 to 1.4 per year, whereas in-office interrogations decreased from 2.8 to 2.7 per year and from 3.0 to 2.9 per year, respectively. Beneficiary-level analysis revealed increased expenditures on remote interrogation offset by decreases in in-office expenditures, with total annual spending decreasing by $2 and $5 per beneficiary, respectively.

CONCLUSION

Remote monitoring utilization increased substantially from 2012 to 2015, whereas annual costs per beneficiary decreased.

Cardiac implantable electronic device remote monitoring in a large cohort of patients and the need for planning

Aim: The remote monitoring (RM) of cardiac implantable electronic devices (CIED) is standard of care. We describe an organizational and projection RM workload model. Methods: At the time of the analysis (2015), 3995 CIED patients were followed-up; 1582 (40.5%) with RM. All RM transmissions (Tx) have been gathered in five event types. Results: We received 10,406 Tx, classified as: 128 (1.2%) red alerts, 141 (1.3%) atrial fibrillation episodes, 1944 (18.6%) yellow alerts, 403 (3.9%) lost Tx (disconnected/noncompliant patients) and 7790 (75.0%) Tx 'OK' (un-eventful Tx). At the time of 100% of remote CIED managed, we can expect a total of 25,990 Tx/year. Conclusion: We provide a descriptive analysis of remote monitoring management and workload estimation in a large cohort of CIED patients.

Cost-utility analysis of telemonitoring versus conventional hospital-based follow-up of patients with pacemakers. The NORDLAND randomized clinical trial

INTRODUCTION

The aim of our study was to perform an economic assessment in order to check whether or not telemonitoring of users with pacemakers offers a cost-effective alternative to traditional follow-up in outpatient clinics.

METHODS

We used effectiveness and cost data from the NORDLAND trial, which is a controlled, randomized, non-masked clinical trial. Fifty patients were assigned to receive either telemonitoring (TM; n = 25) or conventional monitoring (CM; n = 25) and were followed up for 12 months after the implantation. A cost-utility analysis was performed in terms of additional costs per additional Quality-Adjusted Life Year (QALY) attained from the perspectives of the Norwegian National Healthcare System and patients and their caregivers.

RESULTS

Effectiveness was similar between alternatives (TM: 0.7804 [CI: 0.6864 to 0.8745] vs. CM: 0.7465 [CI: 0.6543 to 0.8387]), while cost per patient was higher in the RM group, both from the Norwegian NHS perspective (TM: €2,079.84 [CI: 0.00 to 4,610.58] vs. €271.97 [CI: 158.18 to 385.76]; p = 0.147) and including the patient/family perspective (TM: €2,295.91 [CI: 0.00 to 4,843.28] vs. CM: €430.39 [CI: 0.00 to 4,841.48]), although these large differences-mainly due to a few patients being hospitalized in the TM group, as opposed to none in the CM group-did not reach statistical significance. The Incremental Cost-Effectiveness Ratio (ICER) from the Norwegian NHS perspective (€53,345.27/QALY) and including the patient/caregiver perspective (€55,046.40/QALY), as well as the Incremental Net Benefit (INB), favors the CM alternative, albeit with very broad 95%CIs. The probabilistic analysis confirmed inconclusive results due to the wide CIs even suggesting that TM was not cost-effective in this study. Supplemental analysis excluding the hospitalization costs shows positive INBs, whereby suggesting a discrete superiority of the RM alternative if hospitalization costs were not considered, albeit also with broad CIs.

CONCLUSIONS

Cost-utility analysis of TM vs. CM shows inconclusive results because of broad confidence intervals with ICER and INB figures ranging from potential savings to high costs for an additional QALY, with the majority of ICERs being above the usual NHS thresholds for coverage decisions.

Drowning in Data: Workflow Changes Improve the Collection of Clinically Relevant and Actionable Data

BACKGROUND

The implantable loop recorder (ILR) is valuable for recording and evaluating clinically relevant arrhythmias. Devices with wireless capabilities are programmed to automatically transmit data to a secure website for retrieval by cardiology staff. However, increased data review time, memory saturation, and overwriting of true arrhythmia episodes can result unless alerts are programmed to appropriately detect meaningful (or actionable) cardiac data. Patients are instructed to manually activate the ILR to initiate simultaneous recording of rhythms as part of routine, scheduled assessments or during symptomatic events. However, patients may feel overwhelmed or intimidated when attempting to generate their own cardiac data because of the large volume of new information and unfamiliar equipment instructions.

OBJECTIVE

To determine if workflow changes and enhanced patient education improve the collection of more meaningful data from the ILR.

METHODS

A retrospective chart review was conducted of rhythm data from patients with implantable Medtronic Reveal Linq cardiac monitors. Cardiac rhythm data were gathered three months before and after workflow changes to compare quality and quantity of remote transmissions.

RESULTS

Significant improvements were noted following workflow changes and enhanced patient education. Scheduled transmissions increased, unscheduled transmissions decreased, and missed transmissions decreased per patient each month.

CONCLUSION

Workflow changes improved the quality of transmissions and decreased the quantity of transmissions. The capacity to provide high-quality care also improved, as evidenced by the ability to obtain more clinically relevant and actionable data.

Management of cardiac implantable devices in patients undergoing radiotherapy

The delivery of radiotherapy to patients with a cardiac implantable electronic device (CIED) is not an infrequent event.

INvestigation on Routine Follow-up in CONgestive HearT FAilure Patients with Remotely Monitored Implanted Cardioverter Defibrillators SysTems (InContact)

Background

In heart failure (HF) patients with implantable cardioverter defibrillators (ICD) or cardiac resynchronisation therapy defibrillators (CRT-D), remote monitoring has been shown to result in at least non-inferior outcomes relative to in-clinic visits. We aimed to provide further evidence for this effect, and to assess whether adding telephone follow-ups to remote follow-ups influenced outcomes.

Methods

InContact was a prospective, randomised, multicentre study. Subjects receiving quarterly automated follow-up only (telemetry group) were compared to those receiving personal physician contact. Personal contact patients were further divided into those receiving automated follow-up plus a telephone call (remote+phone subgroup) or in-clinic visits only.

Results

Two hundred and ten patients underwent randomisation (telemetry n = 102; personal contact n = 108 [remote+phone: n = 53; visit: n = 55]). Baseline characteristics were comparable between groups and subgroups. Over 12 months, 34.8% of patients experienced deterioration of their Packer Clinical Composite Response, with no significant difference between the telemetry group and personal care (p > 0.999), remote+phone (p = 0.937) or visit (p = 0.940) patients; predefined non-inferiority criteria were met. Mortality rates (5.2% overall) were comparable between groups and subgroups (p = 0.832/p = 0.645), as were HF-hospitalisation rates (11.0% overall; p = 0.605/p = 0.851). The proportion of patients requiring ≥1 unscheduled follow-up was nominally higher in telemetry and remote+phone groups (42.2 and 45.3%) compared to the visit group (29.1%). Overall, ≥ 1 ICD therapy was delivered to 15.2% of patients.

Conclusion

In HF patients with ICDs/CRT-Ds, quarterly remote follow-up only over 12 months was non-inferior to regular personal contact. Addition of quarterly telephone follow-ups to remote monitoring does not appear to offer any clinical advantage.

Economic impact of remote monitoring after implantable defibrillators implantation in heart failure patients: an analysis from the EFFECT study

Aims

Heart failure (HF) patients with implantable cardioverter-defibrillators (ICD) require admissions for disease management and out-patient visits for disease management and assessment of device performance. These admissions place a significant burden on the National Health Service. Remote monitoring (RM) is an effective alternative to frequent hospital visits. The EFFECT study was a multicentre observational investigation aiming to evaluate the clinical effectiveness of RM compared with in-office visits standard management (SM). The present analysis is an economic evaluation of the results of the EFFECT trial.

Methods and results

The present analysis considered the direct consumption of healthcare resources over 12-month follow-up. Standard tariffs were applied to hospitalizations, in-office visits and remote device interrogations. Economic comparisons were also carried out by means of propensity score (PS) analysis to take into account the lack of randomization in the study design. The analysis involved 858 patients with ICD or CRT-D. Of these, 401 (47%) were followed up via an SM approach, while 457 (53%) were assigned to RM. The rate of hospitalizations was 0.27/year in the SM group and 0.16/year in the RM group (risk reduction =0.59; P = 0.0004). In the non-adjusted analysis, the annual cost for each patient was €817 in the SM group and €604 in the RM group (P = 0.014). Propensity score analysis, in which 292 RM patients were matched with 292 SM patients, confirmed the results of the non-adjusted analysis (€872 in the SM group vs. €757 in the RM group; P < 0.0001).

Conclusion

There is a reduction in direct healthcare costs of RM for HF patients with ICDs, particularly CRT-D, compared with standard monitoring.

Cost-utility analysis on telemonitoring of users with pacemakers: The PONIENTE study

INTRODUCTION

Few studies have confirmed the cost-saving of telemonitoring of users with pacemakers (PMs). The purpose of this controlled, non-randomised, non-masked clinical trial was to perform an economic assessment of telemonitoring (TM) of users with PMs and check whether TM offers a cost-utility alternative to conventional follow-up in hospital.

METHODS

Eighty-two patients implanted with an internet-based transmission PM were selected to receive either conventional follow-up in hospital ( n = 52) or TM ( n = 30) from their homes. The data were collected during 12 months while patients were being monitored. The economic assessment of the PONIENTE study was performed as per the perspectives of National Health Service (NHS) and patients. A cost-utility analysis was conducted to measure whether the TM of patients with PMs is cost-effective in terms of costs per gained quality-adjusted life years (QALYs).

RESULTS

There was a significant cost-saving for participants in the TM group in comparison with the participants in the conventional follow-up group. From the NHS's perspective, the patients in the TM group gained 0.09 QALYs more than the patients in the conventional follow-up group over 12 months, with a cost saving of 57.64% (€46.51 versus €109.79, respectively; p < 0.001) per participant per year. In-office visits were reduced by 52.49% in the TM group. The costs related to the patient perspective were lower in the TM group than in the conventional follow-up group (€31.82 versus €73.48, respectively; p < 0.005). The costs per QALY were 61.68% higher in the in-office monitoring group.

DISCUSSION

The cost-utility analysis performed in the PONIENTE study showed that the TM of users with PMs appears to be a significant cost-effective alternative to conventional follow-up in hospital.

First Magnetic Resonance Managed by a Cardiology Department in the Spanish Public Healthcare System. Experience and Difficulties of an Innovative Model

Magnetic resonance (MR) is considered the gold standard in the assessment of myocardial morphology, function, perfusion, and viability. However, its main limitation is its scarce availability. In 2014, we installed the first MR scanner exclusively managed by a cardiology department within the publicly-funded Spanish healthcare system with the aim of improving patient-care, training and research in the department. In the time interval analyzed, July 2014 to May 2017, 3422 cardiac MR scans were performed (32minutes used per study; 96% with good quality; 75% with contrast media administration). The most prevalent clinical indications were cardiomyopathy (29%) and ischemic heart disease (12%). Twenty-five percent of studies were conducted in the context of research protocols. Follow-up studies predominated among outpatients, while pretherapeutic assessment was more common in hospitalized patients. The presumptive diagnosis was changed by cardiac MR scanning in up to 20% of patients investigated for ischemic heart disease. The installation and operative management of an MR scanner in our cardiology department has allowed us to integrate this technique into daily clinical practice, modify our clinical protocols, optimize access to this technology among cardiac patients, improve training, and conduct clinical research.

The Model for Assessment of Telemedicine (MAST): A scoping review of empirical studies

The evaluation of telemedicine can be achieved using different evaluation models or theoretical frameworks. This paper presents a scoping review of published studies which have applied the Model for Assessment of Telemedicine (MAST). MAST includes pre-implementation assessment (e.g. by use of participatory design), followed by multidisciplinary assessment, including description of the patients and the application and assessment of safety, clinical effectiveness, patient perspectives, economic aspects organisational aspects and socio-cultural, legal and ethical aspects. Twenty-two studies met the inclusion criteria and were included in the review. In this article, research design and methods used in the multidisciplinary assessment are described, strengths and weaknesses are analysed, and recommendations for future research are presented.
