[Basic structural features of a cardiac telemedicine center for patients with heart failure and implanted devices, cardiac arrhythmias, and increased risk of sudden cardiac death : Recommendations of the working group 33 Telemonitoring of the German Cardiac Society]

The present and future of cardiological telemonitoring in Europe: a statement from seven European countries

Cardiovascular diseases remain one of the leading causes of death worldwide, placing a significant burden on individuals, families and healthcare systems. Telemedicine, in particular remote monitoring of patients with cardiovascular diseases, reduces this burden as it links the continuous monitoring of the health status with individual education and adaptation of the therapy to the needs of the patients. This improves patient outcomes and facilitates access to specialised healthcare services, independent of time and distance. Furthermore, telemedicine enables improvements in efficiency and promotes patients' self-care. However, the widespread adoption of remote patient monitoring faces several hurdles. A round table of experts from seven European countries (France, Germany, Italy, Poland, Spain, the Netherlands and the United Kingdom) reviewed the current state of telemedicine within the participating countries in order to learn from each other with an impetus for European co-operation. The creation of reliable regulations, overcoming regional differences, the redefinition of roles and processes, the personalisation of healthcare services, the promotion of innovation and research, the use of artificial intelligence and, finally, the efficient management and safeguarding of healthcare data were identified as key levers for further development of telemedicine. This discussion paper emphasises the need for cross-national research activities, involving all stakeholders, such as researchers, industry and patients, to foster the integration of telemedicine in clinical pathways.

[Telemedical care concepts for heart failure: status and future]

Telemedical care concepts provide opportunities to improve the care of patients with chronic heart failure (CHF). The current state of telemedical technologies enables the effective monitoring of the disease. Germany is one of the first European countries with an entitlement to telemedical supporting care for CHF patients. The decision of the German Federal Joint Committee in 2020 to introduce telemedical supporting care for CHF patients marks a milestone. For the first time, a digital care procedure was included in the benefits catalogue of the statutory health insurance funds due to its proven benefits in terms of morbidity and mortality. Privately insured CHF patients have been entitled to these benefits since January 2024. Future developments, particularly with respect to artificial intelligence procedures in telemedicine, are promising but require more evidence. Further research, technological innovation and supportive policy frameworks are needed to realize the full potential of these approaches. Continued collaboration between healthcare professionals, technology developers and policy makers will be crucial in sustainably improving the care of heart failure patients with telemedicine.

[Digitalization and clinical decision tools]

Digitalization in cardiovascular emergencies is rapidly evolving, analogous to the development in medicine, driven by the increasingly broader availability of digital structures and improved networks, electronic health records and the interconnectivity of systems. The potential use of digital health in patients with acute chest pain starts even in the prehospital phase with the transmission of a digital electrocardiogram (ECG) as well as telemedical support and digital emergency management, which facilitate optimization of the rescue pathways and reduce critical time intervals. The increasing dissemination and acceptance of guideline apps and clinical decision support tools as well as integrated calculators and electronic scores are anticipated to improve guideline adherence, translating into a better quality of treatment and improved outcomes. Implementation of artificial intelligence to support image analysis and also the prediction of coronary artery stenosis requiring interventional treatment or impending cardiovascular events, such as heart attacks or death, have an enormous potential especially as conventional instruments frequently yield suboptimal results; however, there are barriers to the rapid dissemination of corresponding decision aids, such as the regulatory rules related to approval as a medical product, data protection issues and other legal liability aspects, which must be considered.

[Legal aspects of telemedicine in cardiology in Germany]

Since 2016, quarterly telemedical remote monitoring of patients with an implanted defibrillator or cardiac resynchronization therapy (CRT) system is part of the Einheitlichen Bewertungsmaßstab (EBM, physician's fee schedule) and is the first telemedical service to be reimbursed in German cardiology. Many publications like the TIM-HF2 or the InTime trial have shown a significant benefit for different endpoints in patients with advanced heart failure. Therefore, the German Society of Cardiology (DGK) has published different recommendations that emphasize an obvious indication of telemedical care with daily control of implantable cardioverter-defibrillator (ICD) information, parameters like blood pressure and weight, and telemedical counselling of patients with heart failure with reduced ejection fraction. This recommendation is also part of the guidelines of the European Society of Cardiology (ESC) published in 2021. It has a level IIb for patients with heart failure. In December 2020 the "Gemeinsame Bundesausschuss" (G-BA) decided to accept telemonitoring as a diagnostic tool and treatment option for patients with heart failure. This service of physicians became part of the EBM and ever since may be offered to patients. This development is accompanied with many questions regarding a physician's accountability, protection of data privacy, and also regarding the structures given by the G‑BA and the "Kassenärztlichen Vereinigungen" (KV). Thus, this paper tries to give an overview of these topics. It will also provide a critical discussion of these structures and their legal foundation because there are many constraints that need to be taken into consideration as a cardiologist. These constraints may ultimately hinder the expansion of this service to patients in Germany.

Digital Transformation in the Diagnostics and Therapy of Cardiovascular Diseases: Comprehensive Literature Review

BACKGROUND

The digital transformation of our health care system has experienced a clear shift in the last few years due to political, medical, and technical innovations and reorganization. In particular, the cardiovascular field has undergone a significant change, with new broad perspectives in terms of optimized treatment strategies for patients nowadays.

OBJECTIVE

After a short historical introduction, this comprehensive literature review aimed to provide a detailed overview of the scientific evidence regarding digitalization in the diagnostics and therapy of cardiovascular diseases (CVDs).

METHODS

We performed an extensive literature search of the PubMed database and included all related articles that were published as of March 2022. Of the 3021 studies identified, 1639 (54.25%) studies were selected for a structured analysis and presentation (original articles: n=1273, 77.67%; reviews or comments: n=366, 22.33%). In addition to studies on CVDs in general, 829 studies could be assigned to a specific CVD with a diagnostic and therapeutic approach. For data presentation, all 829 publications were grouped into 6 categories of CVDs.

RESULTS

Evidence-based innovations in the cardiovascular field cover a wide medical spectrum, starting from the diagnosis of congenital heart diseases or arrhythmias and overoptimized workflows in the emergency care setting of acute myocardial infarction to telemedical care for patients having chronic diseases such as heart failure, coronary artery disease, or hypertension. The use of smartphones and wearables as well as the integration of artificial intelligence provides important tools for location-independent medical care and the prevention of adverse events.

CONCLUSIONS

Digital transformation has opened up multiple new perspectives in the cardiovascular field, with rapidly expanding scientific evidence. Beyond important improvements in terms of patient care, these innovations are also capable of reducing costs for our health care system. In the next few years, digital transformation will continue to revolutionize the field of cardiovascular medicine and broaden our medical and scientific horizons.

[Acceptance of telemetric care for patients with sICD safety advice : Qualitative interview study in cardiological health services research]

BACKGROUND

Telemonitoring is used to monitor implantable cardioverter defibrillators (ICDs). Despite the scientifically proven effectiveness and safety of telemetric care, studies show that the offer is not used and accepted by all patients.

OBJECTIVES

The aim of this study is to investigate the attitudes of ICD patients towards telemonitoring, including which aspects influence attitudes and decision-making.

METHODS

Data were collected using semi-structured, guideline-based individual interviews. A total of 14 patients with a subcutaneous ICD (sICD) and both primary and secondary prophylactic indications were recruited. Data analysis followed a content-structuring qualitative approach.

RESULTS

Patients with telemonitoring perceived a high benefit with low concerns about digital technology, while the opposite was observed for patients without telemonitoring. The patients' previous medical experience has a crucial impact on the acceptance of telemonitoring. All age groups reported the technical implementation and practical handling of telemonitoring to be simple and uncomplicated.

CONCLUSION

The results suggest that the primary and secondary prophylactic indication for ICD implantation have an influence on the attitude towards telemonitoring and, thus, on acceptance. Further qualitative research regarding user acceptance of telemonitoring of other ICD systems is needed.

[Telemedicine in chronic heart failure-From clinical studies to standard care]

Telemedicine has the potential to solve many current and especially future challenges in medical care. Using the example of heart failure (HF), the transition of telemedicine from clinical studies to standard care is presented. In patients with chronic HF, randomized controlled trials have shown that telemedicine-based care leads to a reduction in mortality and cardiovascular morbidity. Based on these data, the Federal Joint Committee (G-BA) decided that for the first time a digital method should be introduced into standard care for high-risk patients with reduced left ventricular ejection fraction. In the future, this group of patients will be entitled to telemedical care using active rhythm devices or noninvasive measuring devices. The indications are assessed by the primary treating physician (PBA), who works together with a telemedicine center (TMZ) managed through cardiology that receives daily telemetric data and notifies the PBA of abnormal findings. Alternatively, a cardiologist PBA with an associated TMZ infrastructure can also provide telemedical care. In the future, advanced technologies such as artificial intelligence or mobile communication standard 5G will help to make telemedicine both widely available and usable for alternative sensor technology.

Telemedicine in Cardiology: Modern Technologies to Improve Cardiovascular Patients’ Outcomes—A Narrative Review

The registration of physical signals has long been an important part of cardiological diagnostics. Current technology makes it possible to send large amounts of data to remote locations. Solutions that enable diagnosis and treatment without direct contact with patients are of enormous value, especially during the COVID-19 outbreak, as the elderly require special protection. The most important examples of telemonitoring in cardiology include the use of implanted devices such as pacemakers and defibrillators, as well as wearable sensors and data processing units. The arrythmia detection and monitoring patients with heart failure are the best studied in the clinical setting, although in many instances we still lack clear evidence of benefits of remote approaches vs. standard care. Monitoring for ischemia is less well studied. It is clear however that the economic and organizational gains of telemonitoring for healthcare systems are substantial. Both patients and healthcare professionals have expressed an enormous demand for the further development of such technologies. In addition to these subjects, in this paper we also describe the safety concerns associated with transmitting and storing potentially sensitive personal data.

[Position paper on required competencies of nonphysician employees in telemedicine centers]

The non-physician employees in telemedicine centers (TMC) play a decisive role in the care and treatment of patients with heart failure. For this reason, a holistic profile consisting of professional and methodological as well as social and personal competences is necessary, which should be built up or promoted in corresponding training concepts. This position paper underlines the urgency of appropriate and standardized further training of non-physician employees for quality assurance in TMCs and summarizes the requirements for the additional qualification of a telemedical assistant across the board.

Telemedizin bei Herzinsuffizienz – Translation von klinischen Studien in die Regelversorgung

Für telemedizinische Mitbetreuung von Patient*innen mit chronischer Herzinsuffizienz besteht Evidenz bezüglich der Senkung von Letalität und kardiovaskulärer Morbidität. Nach aktuellem Beschluss des Gemeinsamen Bundesausschusses (G-BA) wird erstmals eine digitale Methode in die Regelversorgung überführt. Hochrisikopatient*innen mit reduzierter linksventrikulärer Ejektionsfraktion haben künftig einen Leistungsanspruch, entweder mittels aktiver Implantate (ICD, CRT-P und CRT-D) oder mittels telemedizinischer Heimmessgeräte betreut zu werden. Die Indikation zum Telemonitoring stellt der/die primär behandelnde Arzt/Ärztin (PBA). Der tägliche Vitaldatentransfer erfolgt an ein kardiologisch geführtes Telemedizinzentrum (TMZ), welches den/die PBA bei auffälligen Befunden zeitnah benachrichtigt. Der/die PBA entscheidet im Einzelfall über den Bedarf einer telemedizinischen 24/7-Mitbetreuung. Ein/e kardiologische/r PBA mit einer TMZ-Infrastruktur kann die telemedizinische Mitbetreuung der eigenen Patient*innen übernehmen.

[Structural requirements and prerequisites for outpatient implantation of defibrillators, devices for cardiac resynchronization and event recorders]

Die Möglichkeiten der ambulanten Implantation von Defibrillatoren, Geräten zur kardialen Resynchronisation und Ereignisrekordern („cardiac implantable electronic devices“, CIEDs) gewinnen zunehmend an Bedeutung. In Deutschland existieren aktuell vereinzelte Möglichkeiten zur ambulanten Implantation. Es fehlt allerdings an einheitlichen, anerkannten und verbindlichen Qualitätskriterien sowie an Grundzügen vertraglicher Gestaltungen. Der vorliegende Artikel stellt einen Einblick in die aktuellen Vertragskonstellationen zur ambulanten Operation bereit und definiert ein erstes, holistisches Qualitätskonzept für ambulante Implantationen von CIEDs. Im Zentrum steht das Ziel, einen Diskurs in der Fachgesellschaft anzustoßen, um ein abgestimmtes, verbindliches Qualitätskonzept zu definieren. Dieses sollte als Grundlage für zukünftige Leistungen der ambulanten Implantation dienen, die Leistungen vergleichbar machen und einen Beitrag zum langfristigen Nachweis der Evidenz leisten.

[The wearable cardioverter defibrillator as diagnostic tool : Case report from remote monitoring daily practice]

Eine telemedizinische Versorgung kann neue Einsatzmöglichkeiten bereits etablierter Therapeutika wie einer tragbaren Defibrillator-Weste (WCD) ermöglichen und über ein verbessertes Management von hierüber abgeleiteten Vitaldaten die Versorgungsqualität von chronisch kranken Patienten mit Herzinsuffizienz (HI) erhöhen. Im aktuellen Fallbericht wird der klinische Verlauf eines 71 Jahre alten Patienten beschrieben, der nach einer akuten kardialen Dekompensation und neudiagnostizierter hochgradiger Einschränkung der kardialen Pumpfunktion im Rahmen einer ischämischen Kardiomyopathie leitliniengerecht mit einer WCD bis zur endgültigen Entscheidung über eine ICD-Implantation versorgt wurde. Die durch die WCD gesammelten Vitalwerte wurden über ein Telemedizinzentrum (TMZ) strukturiert ausgewertet und hierbei ein Rezidiv des vorbekannten paroxysmalen Vorhofflimmerns (VHF) entdeckt, was vor einer möglichen Dekompensation durch Anpassung der Medikation und frühzeitiger Initiierung einer Pulmonalvenenisolation (PVI) therapiert werden konnte. Dieser Fall zeigt exemplarisch die Sinnhaftigkeit strukturierter telemedizinischer Intervention auf, die es ermöglicht, etablierte Konzepte der Patientenversorgung sinnvoll zu ergänzen, bestehende Konzepte zu optimieren und die Patientenversorgung signifikant zu verbessern.

Recommendations on the utilization of telemedicine in cardiology

The enormous progress made in recent years in the field of information and communication technology and also in sensor and computer technology has affected numerous fields of medicine and is capable of inducing even radical changes in diagnostic and therapeutic processes. This is particularly true for cardiology, where, for example, telemetric monitoring of cardiac and circulatory functions has been in use for many years. Nevertheless, broad application of newer telemedical processes has not yet been achieved to the extent one would expect from the encouraging results of numerous clinical studies in this field and the state of the art of the underlying technology. In the present paper, the Working Group on Rhythmology of the Austrian Cardiological Society aims to provoke a critical discussion of the digital change in cardiology and to make recommendations for the implementation of those telemedical processes that have been shown to exert positive effects on a wide variety of medical and economic parameters. The greatest benefit of telecardiological applications is certainly to be found in the long-term care of patients with chronic cardiovascular diseases. Accordingly, follow-up care of patients with cardiological rhythm implants, management of chronic heart failure and secondary prevention following an acute cardiac event during rehabilitation are currently the most important fields of application. Telemedicine is intended to enable high-quality and cost-efficient care for an increasing number of patients, whose care poses one of the greatest challenges to our healthcare system. Not least of all, telemedicine should make a decisive contribution to improving the quality of life of this segment of the population by favorably influencing mortality, morbidity and hospitalization as well as the patient's contribution to treatment.

[Present and future relevance of telemedicine in cardiac arrhythmia emergencies]

BACKGROUND

The use of remote monitoring has increased due to recently published randomised studies. However, its benefit during acute rhythm disorders still remains controversial.

OBJECTIVES

The current review describes the current status and highlights possible application of telemedicine during acute rhythm disorders.

MATERIALS AND METHODS

The prerequisites, structural properties of the sender/patient and the receiver of the data/physician are examined and the results of the current literature are presented.

RESULTS

Telemedicine during emergency rhythm disorders are normally reserved for specific scenarios. The lack of 24/7 staff of the receiver/hospital represents the main barrier.

CONCLUSIONS

Remote medicine in the current form is not yet ready to be implemented for acute rhythm disorders. Expansion of currently existing chest pain units (CPUs) might enable this 24/7 service in the near future.

[Constellations of findings and derived treatment interventions in telemedical monitoring of patients with heart failure, cardiac arrhythmia or increased risk for sudden cardiac death : Recommendations of the working group 33 telemonitoring of the German Cardiac Society]

The specification of standard operating procedures (SOPs) is a basic requirement for a successful implementation of telemonitoring with implanted cardiac devices and with external measuring devices in patients with heart failure, cardiac arrhytmia or increased risk of sudden cardiac death. The following article summarizes the possibilities of telemonitoring from a technical and organizational point of view and descibes basic requirements on SOPs. these basic requirements should be further specified and anchored in the organizational structure of the individual telemonitoring concept. Moreover, they should de understood as a basic guideline fpr the actions of telemonitoring center (TMC) employees.
