Telemedicine and Remote Management of Patients with Heart Failure: From Theory to Daily Practice.

Background: Heart failure (HF) is responsible for a high number of hospitalizations, caused by a progressive worsening quality of life. Telemedicine allows for better management of patients' complex conditions, improving the care released. However, the risk of remaining at a testing stage often limits the integration of remote care in daily pathways for HF patients. The aim of this study is to outline the steps needed to integrate telemedicine activities into ordinary HF clinic practices. This methodology is applied to observe activities and trend improvements over a 12-month routine phase. Method: Three steps have been defined for an efficient introduction of remote care services in ordinary activities, integrating them with traditional in-person care: (i) introduction of temporary telemedicine projects, (ii) systematization of telemedicine pathways, and (iii) evaluation of monitoring phase. Observational data have been collected from structured interviews to show the rate of telemedicine activities achieved in clinical practice over the last year. Results: The methodology has been proposed in the HF clinic of the Italian hospital ASST Bergamo Est. After an initial testing phase, in which usability and user experience have been tested, four different remote activities were added: (i) telemonitoring for patients with an implantable device, (ii) follow-up televisits, (iii) nursing telephone support, and (iv) high-intensity telesurveillance pathways for patients after an HF acute event. During the last year, 218 telemonitoring pathways, 75 televisits, 500 telephone calls, and nine telesurveillance pathways have been performed. Success rates were high, and patients gave positive feedback. Conclusion: By integrating multiple telemedicine activities, it has been possible to better manage complex patients, keep track of disease progression, and improve their participation in care.

Telemedicine home-based management in patients with chronic heart failure and diabetes type II: study protocol for a randomized controlled trial.

BACKGROUND: Heart failure and type 2 diabetes are prevalent public health issues in Europe. These complex chronic conditions require extensive pharmacological management, ongoing self-care, and behavioral changes. Despite the known benefits of lifestyle changes, such as regular exercise and better control of blood sugar levels, patients may need help implementing the recommended changes. This study aims to assess the effectiveness of a telemedicine program for managing heart failure and type 2 diabetes at home. The program focuses on promoting lifestyle changes. METHODS AND ANALYSIS: During scheduled outpatient cardiology evaluations, eligible patients are recruited and randomly assigned to either an intervention or control group in a 1:1 ratio. The intervention group receives support from a nursing case manager through a structured home-based teleassistance program and a trainer for daily physical activity stimulation. They also have access to teleconsultations with cardiologists and diabetes specialists as needed, telemonitoring of vital signs, and daily step tracking. An app records and monitors daily drug treatment, glycemia, blood pressure, heart rate, and other clinical parameters. Patients can also self-report symptoms and communicate via a chat and videoconference system with a Nurse Case Manager. The control group receives routine care. Data collection occurs before intervention and 6 months after baseline during a new outpatient cardiology evaluation. The primary outcome is to measure the difference in the distance walked during a 6-min walk test between baseline and after 6 months. The key secondary outcomes include improving the disease status and physical activity profile. Data will be analyzed according to the intention-to-treat principles. DISCUSSION: This study will provide evidence on the efficacy of a telemedicine home-based management model to maintain correct lifestyles in patients with both heart failure and type 2 diabetes, improving self-management, their empowerment on the diseases, and increasing their knowledge and ability to recognize symptoms early.

Integration of a Smartphone HF-Dedicated App in the Remote Monitoring of Heart Failure Patients with Cardiac Implantable Electronic Devices: Patient Access, Acceptance, and Adherence to Use.

(200 w) Introduction. Remote monitoring (RM) of cardiac implantable electronic device (CIED) diagnostics helps to identify patients potentially at risk of worsening heart failure (HF). Additionally, knowledge of patient HF-related symptoms is crucial for decision making. Patient smartphone applications may represent an ideal option to remotely collect this information. PURPOSE: To assess real-world HF patient access, acceptance, and adherence to use of an HF-dedicated smartphone application (HF app). METHODS: In this study, 10 Italian hospitals administered a survey on smartphone/app use to HF patients with CIED. The subgroup who accepted it downloaded the HF app. Mean 1-year adherence of the HF app use was evaluated. RESULTS: A total of 495 patients (67 ± 13 years, 79% males, 26% NYHA III-IV) completed the survey, of which 84% had access to smartphones and 85% were willing to use the HF app. In total, 311/495 (63%) downloaded the HF app. Patients who downloaded the HF app were younger and had higher school qualification. Patients who were ≥60 years old had higher mean 1-year adherence (54.1%) than their younger counterparts (42.7%; p < 0.001). Hospitals with RM-dedicated staff had higher mean 1-year patient adherence (64.0% vs. 33.5%; p < 0.001). Adherence to HF app decreased from 63.3% (weeks_1-13) to 42.2% (weeks_40-52, p < 0.001). CONCLUSIONS: High access and acceptance of smartphones/apps by HF patients with CIED allow HF app use for RM of patient signs/symptoms. Younger patients with higher school qualifications are more likely to accept HF app; however, older patients have higher long-term adherence.

COVID-19 teleassistance and teleconsultation: a matched case-control study (MIRATO project, Lombardy, Italy).

Background: During the COVID-19 pandemic, telemedicine has been recognised as a powerful modality to shorten the length of hospital stay and to free up beds for the sicker patients. Lombardy, and in particular the areas of Bergamo, Brescia, and Milan, was one of the regions in Europe most hit by the COVID-19 pandemic. The primary aim of the MIRATO project was to compare the incidence of severe events (hospital readmissions and mortality) in the first three months after discharge between COVID-19 patients followed by a Home-Based Teleassistance and Teleconsultation (HBTT group) program and those discharged home without Telemedicine support (non-HBTT group). Methods: The study was designed as a matched case-control study. The non-HBTT patients were matched with the HBTT patients for sex, age, presence of COVID-19 pneumonia and number of comorbidities. After discharge, the HBTT group underwent a telecare nursing and specialist teleconsultation program at home for three months, including monitoring of vital signs and symptoms. Further, in this group we analysed clinical data, patients' satisfaction with the program, and quality of life. Results: Four hundred twenty-two patients per group were identified for comparison. The median age in both groups was 70 ± 11 years (62% males). One or more comorbidities were present in 86% of the HBTT patients and 89% in the non-HBTT group (p = ns). The total number of severe events was 17 (14 hospitalizations and 3 deaths) in the HBTT group and 40 (26 hospitalizations and 16 deaths) in the non-HBTT group (p = 0.0007). The risk of hospital readmission or death after hospital discharge was significantly lower in HBTT patients (Log-rank Test p = 0.0002). In the HBTT group, during the 3-month follow-up, 5,355 teleassistance contacts (13 ± 4 per patient) were performed. The number of patients with one or more symptoms declined significantly: from 338 (78%) to 183 (45%) (p < 0.00001). Both the physical (ΔPCS12: 5.9 ± 11.4) component and the mental (ΔMCS12: 4.4 ± 12.7) component of SF-12 improved significantly (p < 0.0001). Patient satisfaction with the program was very high in all participants. Conclusions: Compared to usual care, an HBTT program can reduce severe events (hospital admissions/mortality) at 3-months from discharge and improve symptoms and quality of life.

Improving the user experience of televisits and telemonitoring for heart failure patients in less than 6 months: a methodological approach.

BACKGROUND: With the spread of COVID-19, telemedicine solutions became crucial to release continuous and remote assistance to chronic patients. The rapid transition to telemedicine solutions did not allow a complete assessment of the user experience by both patients and medical personnel. Despite the well-known benefits in remote care, the lack of usability evaluation of already existing technologies for the vital signs measurement has emerged. A telemedicine platform must match video communication between patients and the medical staff with the possibility to measure vital parameters. Furthermore, technological assistance may overcome the unfamiliarity with telemedicine and drastically reduce the learning time for both patients and medical personnel. OBJECTIVES: The research work presents a method to improve the user experience of a telemedicine service based on the combination of televisits and telemonitoring with wearable sensors for heart failure patients. Skilled technological staff is proposed by the presented method to lead the learning process of both medical personnel and patients in order to reach a high level of usability in less than 6 months. METHODS: The proposed method is composed of 5 steps: identification of technological staff and end users; selection of the telemedicine platform; design of questionnaires for usability analysis; training of clinicians and patients; final usability evaluation of the telemedicine platform by means of customized satisfaction questionnaires and Post-Study System Usability Questionnaires (PSSUQs). The methodological approach has been tested in collaboration with a heart failure clinic by involving 5 physicians, 5 nurses, 15 heart failure patients, a research engineer and 4 technicians. A platform with 3 wearable sensors has been chosen: a wireless thermometer, a finger pulse-oximeter and an undershirt have been used for the detection of ECG trace. While these devices allowed asynchronous measurements of physiological data, scheduled televisits have been used for direct communication between physicians and patients. RESULTS: Satisfaction questionnaires of patients and clinicians reached respectively 65.18% and 65.83%, while PSSUQ scores were respectively 91.73% and 81.70%. Both groups of end users confirmed a good level of usability and their satisfaction about the ease of use and the perceived quality of the instrumentation. Moreover, 73% of patients did not require help from caregivers to use the kit of sensors. The results have been reached in 5.5 months according to the aim defined initially. Research engineers have played a crucial role in helping clinicians and patients to improve the user experience with the telemedicine platform. CONCLUSIONS: The high level of usability and satisfaction confirmed that the proposed methodological approach helps to learn the technological features of the telemedicine platforms, which are based on different types of technology, such as web applications, wearable sensors and virtual calls. The positive results with heart failure patients encouraged to plan further research studies by using the designed method with other categories of chronic patients.

An observational registry on efficacy and safety of the right ventricular outflow tract as a site for ICD leads: results of the EFFORT (EFFicacy Of Right ventricular outflow Tract as site for ICD leads) registry.

BACKGROUND: Although pacing from the right ventricular outflow tract (RVOT) has been shown to be safe and feasible in terms of sensing and pacing thresholds, its use as a site for implantable cardioverter defibrillator (ICD) leads is not common. This is probably due to physicians' concerns about defibrillation efficacy. To date, only one randomized trial, involving 87 enrolled patients, has evaluated this issue. OBJECTIVE: The aim of this observational study has been to compare safety (primary combined end point: efficacy of a 14-J shock in restoring sinus rhythm, R wave amplitude >4 mV and pacing threshold <1 V at 0.5 ms) and efficacy (in terms of effectiveness of a 14-J shock in restoring sinus rhythm after induction of VF, secondary end point) of two different sites for ICD lead positioning: RVOT and right ventricular apex (RVA). METHODS: The study involved 185 patients (153 males; aged 67 ± 10 years; range, 28-82 years). Site of implant was left to physician's decision. After implant, VF was induced with a 1-J shock over the T wave or--if this method was ineffective--with a 50-Hz burst, and a 14-J shock was tested in order to restore sinus rhythm. If this energy was ineffective, a second shock at 21 J was administered and--eventually--a 31-J shock followed--in case of inefficacy--by a 360-J biphasic external DC shock. Sensing and pacing thresholds were recorded in the database at implant, together with acute (within 3 days of implant) dislodgement rate. RESULTS: The combined primary end point was reached in 57 patients in the RVOT group (0.70%) and in 81 patients in the RVA group (0.79%). The 14-J shock was effective in 159 patients, 63 in the RVOT group (77%) and 86 in the RVA group (83%). Both the primary and the secondary end points are not statistically different. R wave amplitude was significantly lower in the RVOT group (10.9 ± 5.2 mV vs. 15.6 ± 6.4 mV, p < 0.0001), and pacing threshold at 0.5 ms was significantly higher (0.64 ± 0.25 V vs. 0.52 ± 0.20 V, p < 0.01), but these differences do not seem to have a clinical meaning, given that the lower values are well above the accepted limits in clinical practice. CONCLUSIONS: Efficacy and safety of ICD lead positioning in RVOT is comparable to RVA. Even if we observed statistically significant differences in sensing and pacing threshold, the clinical meaning of these differences is--in our opinion--irrelevant.
