Economic impact of telemedicine in modern medicine

Nergis Inal and Bianca Fara

Telemedicine refers to the remote delivery of healthcare services, including medical consultations, diagnosis, treatment, and monitoring, using technology. It has emerged as a transformative instrument in modern medicine. The aim of this report is to analyze how telemedicine affects healthcare costs, patient outcomes, and access to care in the context of COVID-19 and the expansion of telehealth services

1- What is telemedicine? its use in the past and today

Telemedicine is the use of telecommunications technology that enables professionals to evaluate, diagnose and treat patients who are at some distance from the provider. It involves the use of various technologies such as video or phone calls, text messages, medical data transmission and other secure online platforms. The use of telemedicine has recently undergone rapid growth and proliferation in the last decades also due to the progress in technology, in particular high-speed internet, wearable devices and remote monitoring devices. It includes a broad range of healthcare services such as diagnosis and treatment, monitoring and follow-ups, mental health services or specialist consultations.

Telehealth offers several benefits, among others increased access to healthcare, reduced travel time and costs and improved efficiency for healthcare providers. However, there are also some challenges that need to be faced such as data security, regulatory frameworks and ensuring quality care comparable to in-person visits.

Telemedicine has a rich historical evolution dating back to the 1960s, with early programs founded by governments. While most projects were not self-sustaining and folded when funding ceased, the Memorial University of Newfoundland was the first project able to establish a long-standing telemedicine program, contrasting the fate of others. The project had to face a series of challenges along its journey, encompassing high equipment costs, reliability concerns and occasional unnecessary technological utilization.

The feasibility and effectiveness of telemedicine found expression and implementation across diverse clinical contexts, including anesthesiology, cardiology, dermatology, neurology, oncology, pediatrics, and psychiatry. The landscape of telemedicine experimentation extended beyond traditional healthcare settings to unconventional environments like space, desert warfare, and remote regions like the Antarctic. NASA has long used telemedicine for astronauts, and the military has been involved in mobile health and telemedicine services. The armed forces have deployed telemedicine units in various locations, including Somalia, Haiti, Macedonia, and Croatia.

2- Telemedicine during COVID-19

 Telemedicine gained an important role in people’s lives during the COVID-19 pandemic due to the need for remote medical care to prevent virus transmission. The public health crisis caused by COVID-19 increased the public interest and demand towards expanding this method as an integral part of outpatient care delivery. It has been especially utilized to handle remote consultations for non-emergency primary care and specialist visits, medication management, and mental health support. Moreover, patients with COVID-19 symptoms benefitted from telemedicine for their initial screenings to receive guidance for their next steps. Those with symptoms could have a rapid “video visit” with a doctor or a nurse to avoid going to a clinic teeming with other people who are possibly infected, and they wouldn’t be a risk to the medical professionals who could otherwise be exposed. After the use of telemedicine amid the COVID-19 crisis, clinics started to consider the use of it for other more common infectious diseases such as the seasonal flu to prevent the exposure of other patients and their healthcare providers.

Main advantages of telemedicine, other than the reduced risk of infection, during COVID-19 were the accessibility, the convenience, and the cost effectiveness it provided for both patients and healthcare providers. It allowed patients to receive healthcare regardless of the distance to medical care, while reducing the time and effort associated with traditional in-person visits and eliminating the travel expenses and reduces overhead costs for facilities. Scheffer et al 2022., discovered in their study, in which they have analyzed the responses of 1,183 physicians to a survey on the impact of COVID-19 on their livelihood and working practice, results that suggested telemedicine may have helped ensure and expand the range of communication and healthcare services in low- and middle-income settings during the COVID-19 pandemic.

On the other hand, the COVID-19 pandemic also prompted investigations into the constraints of telemedicine utilization, exploring obstacles, such as socioeconomic and racial/ethnic factors, that impede access to this service. Challenges were identified concerning the quality of care, the lack of physical examinations and imaging, and ethical considerations surrounding the doctor-patient relationship, access, consent, and privacy. The digital divide caused disparities in healthcare access due to the need for necessary technology and a reliable internet connection. Technical issues, such as poor internet connection or unfamiliarity with digital platforms, hindered the effectiveness of telemedicine. The privacy and security concerns were raised about sharing sensitive medical information over digital channels. Moreover, it could not replace the need for in-person assessments that some conditions and specialties heavily rely on.

The COVID-19 pandemic highlighted telemedicine as a transformative force in healthcare, offering crucial benefits like enhanced accessibility and cost-effectiveness. Despite notable advantages, challenges such as the digital divide and limitations in physical examinations emphasize the need for ongoing refinement. The experience gained during the pandemic has sparked discussions on integrating telemedicine into routine healthcare practices, suggesting a potential hybrid model that combines virtual and in-person care for the future.

3- Cost effectiveness

Some studies acknowledge the potential effectiveness of telemedicine in providing health services and reduce healthcare cost, but the conclusions are not universally consistent as there are several methodological weaknesses and limitations due to small sample sizes, limited empirical evidence and a lack of large-scale evaluations and adequate evaluation period. Whitten et al. and Mistry, in their studies, adopt a more cautious perspective as methodological issues lead to inconclusive evidence and doubts concerning the cost-effectiveness of telemedicine and its positive economic effect.

 While the majority of studies indicate potential cost-saving benefits associated with telemedicine, the different outcomes and the limitation in the methodology emphasizes the complexity of these studies to comprehend the economic efficiency, highlighting the need for more robust and standardized evaluations in the future. Future research needs to investigate deeper into evaluating the economic impact of these new technologies and larger-scale studies are necessary to validate the effectiveness of telehealth. It is necessary to provide standardized measures and comprehensive long-term evaluations in order to reduce complexity.

 Studies in Neurology show the potential of telehealth is assessing conditions like Parkinson’s disease using interactive video tools. While initial studies demonstrate success, larger sample sizes are crucial to validate these findings and assess broader applicability. Even cardiology studies have highlighted the promising accuracy rates of cardiac auscultation via telemedicine compared to in-person auscultation, however it is necessary to conduct research with a larger sample to have conclusive results.

 Telemedicine holds promise in revolutionizing healthcare delivery, but its effectiveness and acceptance vary across medical specialties and remains challenging due to limited empirical evidence and inconsistent cost metrics. While initial studies demonstrate potential benefits, extensive research with larger sample sizes and standardized cost-benefit analysis are imperative to validate and optimize telemedicine applications.

4- Paradoxical effect of telemedicine on healthcare disparities

“Health disparities” refer to differences in health outcomes or access to healthcare among different groups of people that are often linked to ocial, economic, and environmental factors, as well as systematic and structural inequalities. The term is also used to characterize inequities in health indicators such as prevalence, frequency, morbidity, and mortality, which arise from unequal access to resources including financial means, autonomy, knowledge, or social capital or by unequal distribution of health services.

 The paradoxical impact of telemedicine on healthcare disparities possesses a dual potential to reduce and intensify already existing inequalities in healthcare access and outcomes. On one hand, telemedicine can improve accessibility by overcoming geographical barriers, offering remote consultations, and reaching underserved populations, particularly benefiting those in rural or remote areas.

 However, the paradox emerges as certain factors further deepen the existing healthcare inequalities. The digital divide, marked by unequal access to technology and the internet, can limit the full utilization of telemedicine services for individuals in economically disadvantaged or marginalized communities, widening the gap between those with and without easy access to telehealth.

 Policymakers need to be aware of the disparities in telemedicine usage among different populations. To fully comprehend the potential of telemedicine, they should advocate targeted measures to address the gaps and hurdles, possibly through regulations ensuring universal access, especially for particular population groups like the elderly and illiterate. Governments may also consider affirmative action for disadvantaged individuals or minority groups in disadvantaged areas.

In order to navigate the paradox, it is important to implement policies and strategies that guarantee equitable access to telemedicine, rectify technological disparities, and sustain a balance between virtual and in-person healthcare to prevent the further deepening of the disparities at hand.
