Usefulness of Remote Monitoring in Cardiac Implantable Device Follow-Up

mHealth in sub-Saharan Africa and Europe: A systematic review comparing the use and availability of mHealth approaches in sub-Saharan Africa and Europe

Background

mHealth can help with healthcare service delivery for various health issues, but there's a significant gap in the availability and use of mHealth systems between sub-Saharan Africa and Europe, despite the ongoing digitalization of the global healthcare system.

Objective

This work aims to compare and investigate the use and availability of mHealth systems in sub-Saharan Africa and Europe, and identify gaps in current mHealth development and implementation in both regions.

Methods

The study adhered to the PRISMA 2020 guidelines for article search and selection to ensure an unbiased comparison between sub-Saharan Africa and Europe. Four databases (Scopus, Web of Science, IEEE Xplore, and PubMed) were used, and articles were evaluated based on predetermined criteria. Details on the mHealth system type, goal, patient type, health concern, and development stage were collected and recorded in a Microsoft Excel worksheet.

Results

The search query produced 1020 articles for sub-Saharan Africa and 2477 articles for Europe. After screening for eligibility, 86 articles for sub-Saharan Africa and 297 articles for Europe were included. To minimize bias, two reviewers conducted the article screening and data retrieval. Sub-Saharan Africa used SMS and call-based mHealth methods for consultation and diagnosis, mainly for young patients such as children and mothers, and for issues such as HIV, pregnancy, childbirth, and child care. Europe relied more on apps, sensors, and wearables for monitoring, with the elderly as the most common patient group, and the most common health issues being cardiovascular disease and heart failure.

Conclusion

Wearable technology and external sensors are heavily used in Europe, whereas they are seldom used in sub-Saharan Africa. More efforts should be made to use the mHealth system to improve health outcomes in both regions, incorporating more cutting-edge technologies like wearables internal and external sensors. Undertaking context-based studies, identifying determinants of mHealth systems use, and considering these determinants during mHealth system design could enhance mHealth availability and utilization.

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.

An Intelligent Remote Monitoring System for Total Knee Arthroplasty Patients

For the first six weeks following total knee arthroplasty (TKA), a patient will attend an outpatient clinic typically seen twice weekly. Here, an exercise regime is performed and improvement assessed using a hand held goniometer that measures the maximum angle of knee flexion, an important metric of progress. Additionally a series of daily exercises is performed at home, recorded in a diary. This protocol has problems. Patients must attend the hospital with assistance since they are not permitted to drive for six weeks following the procedure; appointments are sometimes missed; there are occasionally not enough physiotherapy appointment available; furthermore, it is difficult to be sure that patients are compliant with their exercises at home. The economic and social costs are therefore significant both to the patient and the health service. We describe here an automatic system that performs the monitoring of knee flexion within a domestic environment rather than in a hospital setting. It comprises a master and slave sensor unit that attach using Velcro straps to the thigh and shin above and below the operation wound. The patient performs the prescribed knee exercises whilst wearing the device, during which time it measures and records the angles of knee flexion. The device utilises the Global System for Mobile Communications (GSM) infrastructure to transmit data through the Internet to a secure hospital-based server using an on-board GSM modem. The clinician is then able to view and interpret the information from any computer with internet access and the software. The system does not require the patient to possess a mobile telephone, a computer, or have internet access; the necessary communications technology is completely integrated into the device.

Health Care Utilization and Expenditures Associated With Remote Monitoring in Patients With Implantable Cardiac Devices

Several randomized trials and decision analysis models have found that remote monitoring may reduce health care utilization and expenditures in patients with cardiac implantable electronic devices (CIEDs), compared with in-office monitoring. However, little is known about the generalizability of these findings to unselected populations in clinical practice. To compare health care utilization and expenditures associated with remote monitoring and in-office monitoring in patients with CIEDs, we used Truven Health MarketScan Commercial Claims and Medicare Supplemental Databases. We selected patients newly implanted with an implantable cardioverter defibrillators (ICD), cardiac resynchronization therapy defibrillator (CRT-D), or permanent pacemaker (PPM), in 2009, who had continuous health plan enrollment 2 years after implantation. Generalized linear models and propensity score matching were used to adjust for confounders and estimate differences in health care utilization and expenditures in patients with remote or in-office monitoring. We identified 1,127; 427; and 1,295 pairs of patients with a similar propensity for receiving an ICD, CRT-D, or PPM, respectively. Remotely monitored patients with ICDs experienced fewer emergency department visits resulting in discharge (p = 0.050). Remote monitoring was associated with lower health care expenditures in office visits among patients with PPMs (p = 0.025) and CRT-Ds (p = 0.006) and lower total inpatient and outpatient expenditures in patients with ICDs (p <0.0001). In conclusion, remote monitoring of patients with CIEDs may be associated with reductions in health care utilization and expenditures compared with exclusive in-office care.

Cost-consequence analysis of daily continuous remote monitoring of implantable cardiac defibrillator and resynchronization devices in the UK

AIMS

The need for ongoing and lifelong follow-up (FU) of patients with cardiac implantable electric devices (CIED) requires significant resources. Remote CIED management has been established as a safe alternative to conventional periodical in-office FU (CFU). An economic model compares the long-term cost and consequences of using daily Home Monitoring® (HM) instead of CFU.

METHODS AND RESULTS

A cost-consequence evaluation comparing HM vs. CFU was performed using a Markov cohort model and data relating to events and costs identified via a systematic review of the literature. The model is conservative, without assuming a reduction of cardiovascular events by HM such as decompensated heart failure or mortality, or considering cost savings such as for transportation. Also cost savings due to an improved timing of elective device replacement, and fewer FU visits needed in patients near device replacement are not considered. Over 10 years, HM is predicted to be cost neutral at about GBP 11 500 per patient in either treatment arm, with all costs for the initial investment into HM and fees for ongoing remote monitoring included. Fewer inappropriate shocks (-51%) reduce the need for replacing devices for battery exhaustion (-7%); the number of FU visits is predicted to be halved by HM.

CONCLUSION

From a UK National Health Service perspective, HM is cost neutral over 10 years. This is mainly accomplished by reducing the number of battery charges and inappropriate shocks, resulting in fewer device replacements, and by reducing the number of in-clinic FU visits.

"We as Human Beings Get Farther and Farther Apart": the experiences of patients with remote monitoring systems

OBJECTIVE

To explore the experiences of patients living with an implantable cardioverter-defibrillator (ICD) who had received remote monitoring (RM).

BACKGROUND

Anecdotal evidence suggests that not all patients with RM use the technology.

METHODS

Focus groups of patients with an ICD who received an RM system. Transcripts reviewed using thematic analysis.

RESULTS

Nine patients (3 women and 6 men; median [range] age, 73 [58-91] years) received an RM system. Patients were assigned to a group in regard to RM system use (nonusers, n = 5; users, n = 4). Few nonusers recalled having prior conversations about the system. Users described it as "simple" and "easy" to use. Nonusers often were unsure whether their system was correctly transmitting information. System benefits perceived by users included convenience and security. Nonusers expressed mistrust. Recommendations included early education and help lines.

CONCLUSIONS

Patient adherence to RM systems can be improved by explaining perceived benefits and addressing barriers to use.

Online remote monitoring of patients with differentiated thyroid carcinomas and neuroendocrine tumors treated with high doses of radionuclides

BACKGROUND

Telemedicine could be very useful for patients in remote areas experiencing adverse drug reactions or being in need of sophisticated diagnostic or therapeutic procedures. The aim of this article is to show the experience of our Department of Nuclear Medicine (DNM) in telemonitoring patients with differentiated thyroid carcinomas and neuroendocrine tumors.

SUBJECTS AND METHODS

The DNM at the Clinical Center Kragujevac, Serbia, uses continuous remote monitoring of patients' vital functions, including heart rate, electrocardiogram, respiration rate, blood pressure, and oxygen saturation, as well as video surveillance of the physical isolation area for patients with neuroendocrine tumors (NETs) and some patients with differentiated thyroid carcinomas (DTCs), during administration of radionuclide therapy and for the days following treatment.

RESULTS

The DNM used a telemonitoring system for 156 patients with either DTC or NET who received radionuclide therapy during the last 3 years. There were 32 interventions on patients in the physical isolation area based on changes of the patients' vital functions detected by the telemonitoring system. Twenty-five patients (78%) experienced symptoms, whereas the other seven patients (22%) were symptomless. A responsible physician intervened with treatment of tachycardia (18 cases), hypertension (10 cases), hypotension (2 cases), ventricular extrasystoles (1 case), and ST-segment depression (1 case). After administration of the treatment the health status of the patients was normalized.

CONCLUSION

From our experience gained over the past 3 years, this model of organization and supervision with a telemonitoring system of patients receiving radionuclide therapy ensures a high level of safety for the patient, with significant reduction of staff costs.

Innovation in health care technology: is it part of the problem or part of the solution? eHealth gives the answer

There is no doubt that the contribution of the Health Care Technologies to the tremendous evolution on Medicine since mid XX century has been one of its most important pillars. At the same time the innovation has been sometimes accused of been the root of the increase in the Health Care expenditure to support the Health of the society. Actually, when the Health Care Systems are focusing not only on the critical processes but on the continuum of the disease, the application of innovation to the chronic diseases and, more specifically, in the Cardiovascular ones (specially the Cardiac Insufficiency), represents a great challenge for care givers, patients and the Health Care Systems as their treatment requires continuous medical care and patient self management. The key for establishing this continuity of care in an efficient way is based in the concept of "Anticipation". This is the only way to avoid the burden of the continuous re-hospitalizations of this kind of patients. The engagement of patients in the adoption of healthy lifestyles with a positive impact in the progression of their diseases is fundamental to avoid the appearance of chronic complications or co-morbidities. Only with these assumptions the Innovation on Health Care Technologies will become part of the solution of the sustainability of the Health Care expenditure for the society. This paper present the keys for making the innovation efficient understanding the transversal of the Health Care processes.

Can information technology improve the performance of remote monitoring systems?

Despite some clinical, economic, and other qualitative advantages associated with remote cardiac device monitoring systems, one of the main challenges concerns the management of the out-of-hospital data. Manual updating of hospital databases with the data stored in the manufacturers' servers increases time requirements and may introduce mistakes in the entries. The use of communication standards such as Health Level 7 for data interchange could provide a safe and easy way to access patient and device information. The present study of 38 patients was carried out with the Carelink® remote monitoring technology. A formal process for remote cardiac device monitoring was established, including some features in the Arrhythmias Information System: mobile phone and e-mail were included for communication between patients and hospital, with a new gateway for automatic message sending. Device reports generated through the manufacturer's application were attached to the patient's record. Once the information concerning the transmission session was reviewed, the physician made a medical report, which was sent via post and e-mail to the patient. A new interface was created for Health Level 7 communication with the manufacturers' applications, so that the Arrhythmias Information System could automatically interchange information concerning the device and/or the patient when this kind of communication system is available. The volume of data generated by system warning alerts and transmission sessions makes it very difficult to meet the hospital database updating requirements. Standard-based communication between hospital and manufacturers' applications is fundamental to automatic and reliable update of data.
