Changes in telemedicine use and ambulatory visit volumes at a multispecialty cardiovascular center during the COVID-19 pandemic

Early in the COVID-19 pandemic, cardiology clinics rapidly implemented telemedicine to maintain access to care. Little is known about subsequent trends in telemedicine use and visit volumes across cardiology subspecialties. We conducted a retrospective cohort study including all patients with ambulatory visits at a multispecialty cardiovascular center in Northern California from March 2019 to February 2020 (pre-COVID) and March 2020 to February 2021 (COVID). Telemedicine use increased from 3.5% of visits (1200/33,976) during the pre-COVID period to 63.0% (21,251/33,706) during the COVID period. Visit volumes were below pre-COVID levels from March to May 2020 but exceeded pre-COVID levels after June 2020, including when local COVID-19 cases peaked. Telemedicine use was above 75% of visits in all cardiology subspecialties in April 2020 and stabilized at rates ranging from over 95% in electrophysiology to under 25% in heart transplant and vascular medicine. From June 2020 to February 2021, subspecialties delivering a greater percentage of visits through telemedicine experienced larger increases in new patient visits (r = 0.81, p = 0.029). Telemedicine can be used to deliver a significant proportion of outpatient cardiovascular care though utilization varies across subspecialties. Higher rates of telemedicine adoption may increase access to care in cardiology clinics.

Exploring the challenges to using telecardiology as perceived by pre-hospital emergency care personnel: a qualitative study

BACKGROUND

Today, using the medical technology of telecardiology, as part of advanced medical services, plays an essential role in providing care to cardiac patients in life-threatening conditions who need emergency care. However, pre-hospital emergency care personnel are faced with certain challenges in using telecardiology, with adverse effects on their performance. Therefore, the present study aimed to investigate the challenges to using telecardiology as viewed by pre-hospital emergency care personnel in Southern Iran.

METHODS

The present study is a qualitative work of research with a content analysis approach. Selected using purposeful sampling, 19 pre-hospital emergency care personnel were interviewed on a semi-structured, personal, in-depth basis. The qualitative data obtained were analyzed using the Graneheim and Lundman's conventional content analysis approach (2004).

RESULTS

Based on the qualitative data analysis, 3 themes and 8 subthemes were obtained. The three main themes included professional barriers (lack of clinical knowledge of telecardiology, lack of clinical skill in telecardiology, violation of patients' privacy, lack of clinical guidelines on telecardiology), medical equipment and telecommunication barriers (poor reception and ineffective means of communication, low charge on the battery of tele-electrocardiogram machines), and organizational management barriers (serious lack of cardiologists available for medical counseling and lack of continual personal development of the telecardiology personnel).

CONCLUSION

Senior managers in pre-hospital emergency care services are recommended to use the results of this study to identify the influential factors in using telecardiology and take the necessary measures to eliminate the existing barriers toward making optimal use of telemedicine, thereby improving the quality of care provided for cardiac patients.

[Pediatric telecardiology experience in the COVID-19 pandemic context]

Introduction

The COVID-19 pandemic has caused a global impact on public health services. Using new strategies through telehealth for the management of patients with congenital heart disease was the challenge.

Objective

To describe the experience in telecardiology, and the strategies implemented during the pandemic.

Method

Retrospective, qualitative study that includes the period from April 2020 to April 2021. Inquiries were received through the service's official e-mail or telephone. They were classified according to the type of concern and complexity of heart disease using color coding. The responses were asynchronous (by e-mail) or synchronous (videoconferences). The videoconferences were made using a secure platform (Cisco-Webex).

Results

From April 2020 to April 2021, a total of 3372 queries were answered. The responses were distributed via e-mail (64.9%), phone calls (1.2%) and videoconferences (14.5%). The most frequent reasons for consultation were the request for missed appointments (68%), and remote clinical monitoring (20%). A total of 2296 families was contacted. Only 14.1% of the inquiries were cited in person. With color coding, a stratification was performed according to urgency.

Conclusions

Telehealth proved to be a useful tool for the clinical management of patients with congenital heart disease in their place of origin. It prevented a considerable number of transfers, identified patients at risk rapidly, comforted families, and strengthened ties with local hospitals that make up the health network.

Remote Monitoring of Patients with Implantable Devices-Telemonitoring and Chronic Diseases

The high health care costs and poor quality associated with heart failure have led to the development of remote patient monitoring (RPM or RM) systems and cost-effective disease management strategies. RM of cardiac implantable electronic devices (CIEDs) is the application of communication technology to patients carrying a pacemaker (PM), an implantable cardioverter defibrillator (ICD) for cardiac resynchronization therapy (CRT) or an implantable loop recorder (ILR). The aim of this study is to define and analyze the benefits of modern telecardiology to provide patients with remote clinical assistance especially for patients with implantable devices for early detection of the development of heart failure as well as the limitations inherent therein. Furthermore, the study examines the benefits of telemonitoring in chronic and cardiovascular diseases proposing holistic care. A systematic review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses-PRISMA methodology. The results highlight that telemonitoring has augmented beneficial effects on clinical outcomes of heart failure, including, a reduction in mortality, heart failure hospitalization, all cause hospitalization and also an improvement in Quality of Life.

Layman electrocardiographic screening using smartphone-based multiple‑lead ECG device in school children

BACKGROUND

Pre-partecipation ECG screening of large populations has a significant socioeconomic impact. Technological progress now allows for high-tech-low-cost ECG screening using validated smartphone-based devices capable of guiding to the correct performance of a 12‑lead ECG by layman with no medical background.

METHODS

We enrolled 728 (364, 52% males) individuals, aged 12-13 years who underwent ECG screening with a smartphone 12‑lead ECG during school hours by layman volunteers. Correct electrodes placement was provided by a validated image-processing algorithm by the smartphone camera in the App. ECG interpretation was via a telecardiology platform and alterations classified following current standards.

RESULTS

A total of 741 ECGs were recorded, of which 13(2%) were technically not interpretable. Mean PR, QRS and QTc were: 145 ± 22, 85 ± 19 and 387 ± 57 msec. No QTc prolongation was observed. Mean QRS axis was 15°; 26 (4%) patients presented an iRBB. T-wave inversion from V1-V3 was present in 145 (21%) subjects. Twenty-one(3%) patients were referred to second level examination: deep Q-waves in inferior leads in 12(1.6%), ventricular ectopics in 5(0.7%), anterior T-waves inversions V1-V4 in 3(0.4%); extreme right axis deviation in 1(0.3%). Second line investigations did not provide any definitive diagnosis. Total project costs (material equipment and human cost) was 14.460€, 19.51€ per individual. The potential net saving with respect to current pre-participation screening cost was 19%.

CONCLUSIONS

Layman 12‑lead Smartphone-ECG population screening proved feasible and effective, with a rate of non-interpretable ECG of <5%. Potential cost-saving in ECG screening and recording was 19%, providing an appealing opportunity when large campaigns should be addressed also in developing countries.

Telehealth: A winning weapon to face the COVID-19 outbreak for patients with pulmonary arterial hypertension

Background

COVID-19 pandemic severely affected national health systems, altering the modality and the type of care of patients with acute and chronic diseases. To minimize the risk of exposure to SARS-CoV2 for patients and health professionals, face-to-face visits were cancelled or postponed and the use of telemedicine was strongly encouraged. This reorganization involved especially patients with rare diseases needing periodic comprehensive assessment, such as pulmonary arterial hypertension (PAH).

Main body

The paper reports a proposal of strategy adopted for patients followed at our PAH center in Rome, where patients management was diversified based on clinical risk according to the European Society of Cardiology/European Respiratory Society PH guidelines-derived score and the REVEAL 2.0 score. A close monitoring and support of these patients were made possible by policy changes reducing barriers to telehealth access and promoting the use of telemedicine. Synchronous/asynchronous modalities and remote monitoring were used to collect and transfer medical data in order to guide physicians in therapeutic-decision making. Conversely, the use of implantable monitors providing hemodynamic information and echocardiography-mobile devices wirelessly connecting was limited by the poor experience existing in this setting. Large surveys and clinical trials are welcome to test the potential benefit of the optimal balance between traditional PAH management and telemedicine opportunities.

Conclusion

Italy was found unprepared to manage the dramatic effects caused by COVID-19 on healthcare systems. In this emergency situation telemedicine represented a promising tool especially in rare diseases as PAH, but was limited by its scattered availability and legal and ethical issues. Cohesive partnership of health care providers with regional public health officials is needed to prioritize PAH patients for telemedicine by dedicated tools.

Telecardiology interventions for patients with cardiovascular Disease: A systematic review on characteristics and effects

INTRODUCTION

The prevalence and mortality of cardiovascular diseases are high worldwide. Telecardiology can be used to diagnose and treat these diseases. This paper aimed to review the effectiveness (positive and negative) of implemented telecardiology services in terms of clinical, economic, and patient-reported aspects.

METHODS

A comprehensive search was conducted in Medline (through PubMed), Scopus, ISI web of science, and IEEE Xplore databases from inception to April 7, 2021. the studies that examined the effectiveness of telecardiology interventions were included.

RESULTS

Fifty studies were included in this systematic review. Most investigations (22%) were conducted in the US. In 22% of studies, telecardiology intervention was used for patients with heart failure. Telecardiology has been used in most studies for tele-monitoring (n = 21, 42%) and tele-consultation (n = 17, 34%) and in 29 studies (58%), was applied for ECG transmission. The highest rate of effects reported by studies was clinical. Thirty-five studies (70%) reported the clinical effects; twenty-one studies reported the positive effects for the economic category, and fifteen studies reported the positive effect for patient-reported class. The most positive clinical effects of telecardiology were early diagnosis, early treatment, and mortality reduction. The most positive effect of the economic class was the reduction of health care costs. The most effects of the patient-reported category were improving the patient's quality of life and patient satisfaction.

CONCLUSION

Telecardiology can help early diagnosis and treatment of cardiovascular diseases. It also has great potential in reducing health care costs and increasing quality of life and patient satisfaction.

Scheduled versus alert transmissions for remote follow-up of cardiac implantable electronic devices: Clinical relevance and resource consumption

BACKGROUND

The remote follow-up of pacemakers and implantable cardiac defibrillators (ICDs) usually includes scheduled checks and alert transmissions. However, this results in a high volume of remote data reviews to be managed. We measured the relative contribution of scheduled and alert transmissions to the detection of relevant conditions, and the workload generated by their management.

METHODS

At our center, the frequency of remote scheduled transmissions is 4/year. Moreover, all system-integrity and clinical alerts are turned on for wireless notification. We calculated the number of transmissions received from January to December 2020, and identified transmissions that necessitated in-hospital access for further assessment and transmissions that required clinical discussion with the physician. For all alert transmissions, we identified whether the alert was clinically meaningful (i.e. center was not previously aware of the condition and no action had yet been taken to treat it).

RESULTS

Of 8545 transmissions received from 1697 pacemakers and ICDs, 5766 (67%) were scheduled and 2779 (33%) were alert transmissions received from 764 patients (45%); 499 (9%) scheduled transmissions required clinical discussion with the physician, but only 2 of these necessitated in-hospital visits for further assessment. Of the alert transmissions, 664 (24%) required clinical discussion, and 75 (3%) necessitated in-hospital visits. The proportion of alerts judged clinically meaningful was 7%.

CONCLUSION

Scheduled transmissions generate 67% of remote data reviews for pacemakers and ICDs, but their ability to detect clinically relevant events is very low. A strategy that relies exclusively on alert transmissions could ensure continuity of patient monitoring while reducing the workload at the center.

COVID-19 and STEMI: The role of telecardiology in the management of STEMI diagnosis during COVID 19 pandemic

BACKGROUND

Telecardiology has the advantage of reducing patient's access time to the hemodynamics units. Data from literature show a reduction in ST-elevation myocardial infarction (STEMI) during COVID-19 pandemic. However, there is a low number of studies on the impact of telecardiology during the pandemic.

METHODS

Our telecardiology system is composed of a Hub-and-Spoke network of hospitals and ambulances that ensures a rapid exchange of information allowing STEMI patients to be treated in the shortest time possible. We compared data from electrocardiograms (ECGs) transmissions and STEMI diagnosis collected between February and April 2020 with the data from the same period of 2019.

RESULTS

Despite a significant reduction of ECGs transmissions from the telecardiology network was observed, the number of diagnosed STEMI during 2020 was stable and did not show any significant difference compared to 2019. The total number of STEMI diagnosis in the months under examination during 2019 were 47 out of 7463 ECGs (0.63%), while in 2020 were 48 out of 5797 ECGs (0.83%).

CONCLUSIONS

The efficiency of our telecardiology system along with the low spread of the infection in our region contributed to maintaining the number of STEMI diagnosis and patient's care in line with the past even during the pandemic.

Short-term outcome associated with remote evaluation (telecardiology) of patients with cardiovascular diseases during the COVID-19 pandemic

Introduction

During the recent COVID-19 outbreak, Italian health authorities mandated to replace in-person outpatient evaluations with remote evaluations.

Methods

From March 16th 2020 to April 22th 2020, all outpatients scheduled for in-person cardiac evaluations were instead evaluated by phone. We aimed to report the short-term follow-up of 345 patients evaluated remotely and to compare it with a cohort of patients evaluated in-person during the same period in 2019.

Results

During a mean follow-up of 54 ± 11 days, a significantly higher proportion of patients evaluated in-person in 2019 visited the emergency department or died for any cause (39/391, 10% versus 13/345 3.7%, p = 0.001) and visited the emergency department for cardiovascular causes (19/391, 4.9% versus 7/345, 2.0%, p = 0.04) compared to 2020. No cardiovascular death was recorded in the two periods. To an evaluation with a satisfaction questionnaire 49% of patients would like to continue using remote controls in addition to traditional ones.

Conclusion

These findings may have important implications for the management of patients during the current COVID-19 pandemic because they suggest that remote cardiovascular evaluations may replace in-hospital visits for a limited period.

How to develop a sustainable telemedicine service? A Pediatric Telecardiology Service 20 years on - an exploratory study

Background

Telemedicine services are promoting more access to healthcare. Portugal was an early adopter of telemedicine to overcome both its geological barriers and the shortage of healthcare professionals. The Pediatric Cardiology Service (PCS) at Coimbra University Hospital Centre (CHUC) has been using telemedicine to increase access and coverage since 1998. Their Pediatric Telecardiology Service has been daily connecting CHUC with 13 other Portuguese national hospitals, and regularly connecting with Portuguese-speaking African countries, through a teleconsultation platform.

Methods

This study aims at exploring the Pediatric Telecardiology Service’s evolution, through a comprehensive assessment of the PCS’s development, evolution and impact in public health, to better understand the critical factors for implementation and sustainability of telemedicine, in the context of healthcare services digitalization. A case study was performed, with cost-benefit, critical factors and organizational culture assessment. Finally, the Kingdon’s framework helped to understand the implementation and scale-up process and the role of policy-making.

Results

With the total of 32,685 out-patient teleconsultations, growing steadily from 1998 to 2016, the Pediatric Telecardiology Service has reached national and international recognition, being a pioneer and an active promotor of telemedicine. This telemedicine service has saved significant resources, about 1.1 million euros for the health system (e.g. in administrative and logistic costs) and approximately 419 euros per patient (considering an average of 1777 patients per year).

PCS presents a dominant “Clan” culture. The Momentum’s critical factors for telemedicine service implementation enabled us to understand how barriers were overcome (e.g. political forces). Willingness, perseverance and teamwork, allied with partnership with key stakeholders, were the foundation for professionals’ engagement and service networking development. Its positive results, new regulations and the increasing support from the hospital board, set up a window of opportunity to establish a sustainable telemedicine service.

Conclusion

The Pediatric Telecardiology Service enables real-time communication and the sharing of clinical information, overcoming many barriers (from geographical ones to shortage of healthcare professionals), improving access to specialized care both in Portugal and Africa.

Motivation and teamwork, and perseverance, were key for the Pediatric Telecardiology Service to tackle the window of opportunity which created conditions for sustainability.

Real-World Evaluation of the Eko Electronic Teleauscultation System

Heart murmur evaluation is the most common cause of referral to cardiology, and auscultation of heart sounds with a stethoscope remains a key component of the initial cardiovascular exam. Adoption of telecardiology has been limited by challenges in teleauscultation. We set out to compare in-person auscultatory findings with heart sounds recorded by the Core stethoscope (Eko, Berkeley, CA) in patients with normal heart sounds, innocent heart murmurs, and a variety of pathologic findings. Our study demonstrates that Eko recordings had a high percent of agreement with in-person auscultation findings and echocardiogram findings, with moderate inter-rater reliability. It was useful in identifying patients with pathologic murmurs who would benefit from further assessment. It was able to discern major types of pathological murmurs. Certain qualitative differences in the recorded sounds as compared to in-person auscultation were identified by the reading cardiologists. They were able to acclimate to these subtle differences. The system was felt to be easy to use, and most cardiologists in the study would consider using it in clinical settings. The Eko Core system may be a useful screening tool for murmur evaluation.

Long-term impact of a six-month telemedical care programme on mortality, heart failure readmissions and healthcare costs in patients with chronic heart failure

AIMS

The TElemonitoring in the MAnagement of Heart Failure (TEMA-HF) 1 long-term follow-up study assessed whether an initial six-month telemonitoring (TM) programme compared with usual care (UC) would result in reduced all-cause mortality, heart failure admissions and healthcare costs in chronic heart failure (CHF) patients at long-term follow-up.

METHODS

Of the 160 patients included in the multi-centre, randomised controlled telemonitoring trial (TEMA-HF 1, time point t₀); 142 CHF patients (65% male; age: 76 ± 10 years; EF: 36 ± 15%) were alive and entered the follow-up study (time point: t₁) with a final evaluation at 79 months (time point: t₂). Both TM and UC group patients received standard heart failure care during the follow-up study (time points: t₁ - t₂). The primary endpoint was all-cause mortality. Secondary outcomes included days lost due to heart failure readmissions and readmission/patient follow-up related healthcare costs.

RESULTS

Compared with usual care, the initial six-month TM programme had no significant effect on all-cause mortality (hazard ratio: 0.83; 95% confidence interval, 0.57 to 1.20; p = 0.32). The number of days lost due to heart failure readmissions was significantly lower in the TM group ( p = 0.04). Healthcare costs did not differ significantly between the TM (€ 9140 ± 10580) and UC group (€ 12495 ± 22433) ( p = 0.87).

DISCUSSION

An initial six-month telemonitoring programme was not associated with reduced all-cause mortality in CHF patients at long-term follow-up but resulted in a reduction in the number of days lost due to heart failure readmissions. This study is registered in the ClinicalTrials.gov registry (NCT03171038) (URL: https://clinicaltrials.gov/ct2/show/NCT03171038 ).

ANMCO/SIT Consensus Document: telemedicine for cardiovascular emergency networks

Telemedicine has deeply innovated the field of emergency cardiology, particularly the treatment of acute myocardial infarction. The ability to record an ECG in the early prehospital phase, thus avoiding any delay in diagnosing myocardial infarction with direct transfer to the cath-lab for primary angioplasty, has proven to significantly reduce treatment times and mortality. This consensus document aims to analyse the available evidence and organizational models based on a support by telemedicine, focusing on technical requirements, education, and legal aspects.

Telehealth solutions to enable global collaboration in rheumatic heart disease screening

Background The global burden of rheumatic heart disease is nearly 33 million people. Telemedicine, using cloud-server technology, provides an ideal solution for sharing images performed by non-physicians with cardiologists who are experts in rheumatic heart disease. Objective We describe our experience in using telemedicine to support a large rheumatic heart disease outreach screening programme in the Brazilian state of Minas Gerais. Methods The Programa de Rastreamento da Valvopatia Reumática (PROVAR) is a prospective cross-sectional study aimed at gathering epidemiological data on the burden of rheumatic heart disease in Minas Gerais and testing of a non-expert, telemedicine-supported model of outreach rheumatic heart disease screening. The primary goal is to enable expert support of remote rheumatic heart disease outreach through cloud-based sharing of echocardiographic images between Minas Gerais and Washington. Secondary goals include (a) developing and sharing online training modules for non-physicians in echocardiography performance and interpretation and (b) utilising a secure web-based system to share clinical and research data. Results PROVAR included 4615 studies that were performed by non-experts at 21 schools and shared via cloud-telemedicine technology. Latent rheumatic heart disease was found in 251 subjects (4.2% of subjects: 3.7% borderline and 0.5% definite disease). Of the studies, 50% were preformed on full functional echocardiography machines and transmitted via Digital Imaging and Communications in Medicine (DICOM) and 50% were performed on handheld echocardiography machines and transferred via a secure Dropbox connection. The average time between study performance date and interpretation was 10 days. There was 100% success in initial image transfer. Less than 1% of studies performed by non-experts could not be interpreted. Discussion A sustainable, low-cost telehealth model, using task-shifting with non-medical personal in low and middle income countries can improve access to echocardiography for rheumatic heart disease.

Atrial fibrillation: prevalence in a large database of primary care patients in Brazil

AIMS

Although an increasing prevalence of atrial fibrillation (AF) has been reported worldwide, there are few studies from low- and middle-income countries. Our objective is to assess the prevalence of AF and the associated medical conditions in Brazilian primary care patients.

METHODS AND RESULTS

This is an observational retrospective study. Patients ≥5 years of age from primary care centres of 658 municipalities in Minas Gerais, Brazil, who performed digital electrocardiograms (ECGs) by a public telehealth service in 2011 were assessed. Clinical data were self-reported, and ECGs were interpreted by a team of trained cardiologists using standardized criteria. To assess the relation between clinical characteristics and AF, odds ratios were estimated by logistic regression. A total of 262 685 primary care patients were included, mean (SD) age of 50.3 (19.3) years, 59.6% female. Hypertension was reported in 32.0%, family history of coronary heart disease in 15.0%, diabetes in 5.4%, hyperlipidaemia in 2.8%, Chagas disease in 2.9%, and 7.1% reported current smoking. The prevalence of AF was 1.8% overall: 2.4% in men (ranging from 0.001% from 5-19 years old to 14.6% in nonagenarians) and 1.3% in women (ranging from 0.001% from 5-19 years old to 8.7% in nonagenarians) (P < 0.001). The prevalence of AF increased with advancing age. The comorbidities associated with AF were Chagas disease, previous myocardial infarction, hypertension, and chronic obstructive pulmonary disease. Vitamin K antagonist use was reported by 1.5% of patients.

CONCLUSION

The prevalence and age distribution of AF were similar to studies in high-income countries. The proportion of patients who reported the use of anticoagulants was alarmingly low. Our findings point out the necessity to formulate effective treatment strategies for AF in Brazilian primary care settings.

Design and Implementation of a Telecardiology System for Mobile Devices

This paper presents the design and implementation of a system for digital telecardiology on mobile devices called Remote Cardio Consultation (RCC). Using RCC may improve first intervention procedures in case of heart attack. In fact, it allows physicians to remotely consult ECG signals from a mobile device or smartphone by using a so-called app. The remote consultation is implemented by a server application collecting physician availability to answer upon client support requests. The app can be used by first intervention clinicians and allows reducing delays and decision errors in emergency interventions. Thus, best decision, certified and supported by cardiologists, can be obtained in case of heart attacks and first interventions even by base medical doctors able to produce and send an ECG. RCC tests have been performed, and the prototype is freely available as a service for testing.

Speed and accuracy of text-messaging emergency department electrocardiograms from a small community hospital to a provincial referral center

BACKGROUND

Currently, transmission of electrocardiograms (EKGs) from a small emergency department (ED) to specialists at referral hospitals can be a time-consuming and laborious process. We investigate whether text messaging by use of short message service (SMS) of EKGs from a small hospital to consultants at a large hospital is rapid and accurate.

METHODS

This study involved a one-month prospective evaluation of consecutive EKGs recorded in a small community ED. Investigators obtained de-identified photographs of each EKG via a mobile phone camera. Each EKG picture, along with a brief patient clinical history, was sent via SMS to on-call emergency physicians located at a large referral care site. All images were evaluated solely on a mobile phone. The primary outcome was the proportion of SMS that were received within two minutes of being sent. As a secondary outcome, the intra-rater evaluation of the initial EKG and the SMS EKG image were compared on 13 standardized features. The tertiary outcome was cost of text messaging.

RESULTS

A total of 298 patients (14.6%) had 409 EKGs performed and a total of 926 SMS were sent. 921 SMS (99.5%, 95% confidence interval (CI) 98.7-99.8%) arrived within two minutes with a median transmission time of nine seconds (interquartile range (IQR) 3-32 s). Between the gold standard original EKG, and the interpretation of the texted image, six out of 409 (1.5%, 95% CI 0.6-3.3%) had any differences recorded, across all 13 categories. Overall, the study cost 4.1 cents per texted image.

CONCLUSIONS

Systematic text messaging of ED EKGs from a small community hospital to a referral center is a rapid, accurate, portable, and inexpensive method of data transfer. This may be a safe and effective strategy to communicate vital patient information.

Telemedicine for cardiovascular disease continuum: A position paper from the Italian Society of Cardiology Working Group on Telecardiology and Informatics

Telemedicine is the provision of health care services, through the use of information and communication technology, in situations where the health care professional and the patient, or 2 health care professionals, are not in the same location. It involves the secure transmission of medical data and information, through text, sound, images, or other forms needed for the prevention, diagnosis, treatment, and follow-up of a patient. First data on implementation of telemedicine for the diagnosis and treatment of acute myocardial infarction date from more than 10 years ago. Telemedicine has a potential broad application to the cardiovascular disease continuum and in many branches of cardiology, at least including heart failure, ischemic heart disease and arrhythmias. Telemedicine might have an important role as part of a strategy for the delivery of effective health care for patients with cardiovascular disease. In this document the Working Group on Telecardiology and Informatics of the Italian Society of Cardiology intends to remark some key-points regarding potential benefit achievable with the implementation of telemedicine support in the continuum of cardiovascular disease.

The impact of telemedicine in cardiac critical care

Telemedicine was recognized in the 1970s as a legitimate entity for applying the use of modern information and communications technologies to the delivery of health services. Telecardiology is one of the fastest growing fields in telemedicine. The advancement of technologies and Web-based applications has allowed better transmission of health care delivery. This article discusses current advancements, the scope of telemedicine in cardiology, and its application to the critically ill. The impact of telecardiology consultation continues to evolve and includes many promising applications with potential positive implications for admission rates, morbidity, and mortality.

Role of patient education in the perception and acceptance of home monitoring after recent implantation of cardioverter defibrillators: the EDUCAT study

BACKGROUND

Much attention is being paid to the education of and provision of medical information to patients, to optimize their understanding and acceptance of their disease.

AIMS

To ascertain the impact of educating recent recipients of an implantable cardioverter defibrillator (ICD) on their perception and acceptance of a home monitoring (HM) system.

METHODS

Questionnaire 1, completed one month after ICD implantation, was designed to assess: the quality of patient preparation for HM; patient comprehension of HM; and patient anxiety experienced during its installation. The comprehension questions were assigned a score of -2 for an incorrect answer, +1 for a correct answer and 0 for neither (total score ranging from -40 to +20). Questionnaire 2, completed six months after ICD implantation, assessed patient acceptance of and anxiety about HM.

RESULTS

The registry included 571 patients (mean age 63.9±12.8 years; 83% men; 76% of ICDs implanted for primary prevention) followed by HM for 6.2±1.2 months. Questionnaire 1 was completed by 430 (75.3%) patients and questionnaire 2 by 398 (69.7%) patients. Younger patients had a better comprehension of HM than older patients. High-quality training conditions improved the comprehension score, and a positive association was observed between anxiety and acceptance levels and the comprehension score. The 80±20% mean data transmission rate (days of transmission/days of follow-up ratio) was unrelated to the comprehension scores.

CONCLUSION

A clear understanding was associated with a higher acceptance of HM, although it was unrelated to the data transmission rate.

Does the use of structured reporting improve usability? A comparative evaluation of the usability of two approaches for findings reporting in a large-scale telecardiology context

One of the main reasons that leads to a low adoption rate of telemedicine systems is poor usability. An aspect that influences usability during the reporting of findings is the input mode, e.g., if a free-text (FT) or a structured report (SR) interface is employed. The objective of our study is to compare the usability of FT and ST telemedicine systems, specifically in terms of user satisfaction, efficiency and general usability. We comparatively evaluate the usability of these two input modes in a telecardiology system for issuing electrocardiography reports in the context of a statewide telemedicine system in Brazil with more than 350.000 performed tele-electrocardiography examinations. We adopted a multiple method research strategy, applying three different kinds of usability evaluations: user satisfaction was evaluated through interviews with seven medical professionals using the System Usability Scale (SUS) questionnaire and specific questions related to adequacy and user experience. Efficiency was evaluated by estimating execution time using the Keystroke-Level Model (KLM). General usability was assessed based on the conformity of the systems to a set of e-health specific usability heuristics. The results of this comparison provide a first indication that a structured report (SR) input mode for such a system is more satisfactory and efficient with a larger conformity to usability heuristics than free-text (FT) input. User satisfaction using the SUS questionnaire has been scored in average with 58.8 and 77.5 points for the FT and SR system, respectively, which means that the SR system was rated 18.65 points higher than the FT system. In terms of efficiency, the completion of a findings report using the SR mode is estimated to take 8.5s, 3.74 times faster than using the FT system (31.8s). The SR system also demonstrated less violations to usability heuristics (8 points) in comparison to 14 points observed in the FT system. These results provide a first indication that the usage of structured reporting as an input mode in telecardiology systems may enhance usability. This also seems to confirm the advantages of the usage of structured reporting, as already described in the literature for other areas such as teleradiology.
