Recent history has seen the medical profession undergo a lot of upheaval with telemedicine being one of the most important developments in it. Telemedicine or delivery of health care via technology at distances has been around decades ago in some form or another. Its widespread application, however, has been increased many-fold in recent years, particularly due to the global COVID-19 pandemic, which forced the health care system to rethink the provision of medical care. Telemedicine not only enhanced the availability of medical care but also revolutionized the interactions between patients and physicians.
This piece addresses telemedicine growth in the context of the technological advances that have fueled it, its benefits and limitations, and the future of remote care.
What is Telemedicine?
Telemedicine is the use of electronic media to deliver health services remotely. Telemedicine allows healthcare workers to diagnose, treat, and consult patients remotely through the utilization of electronic communication media such as video calls, calls, and messages. Telemedicine involves extensive technology but it is focused on two fronts: remote consultation and remote monitoring of patients.
- Remote Consultations: They are voice or video consultations between doctors and patients. The patient can either be at home or a remote location, but the doctor or specialist can provide consultation, prescription, and follow-up services utilizing telecommunication equipment.
- Remote Patient Monitoring: This is the use of equipment to capture patients’ health information in real-time and transmit it to care providers for observation and ongoing monitoring. This is very helpful in chronic diseases since patients can be monitored without frequent visits to the doctor’s clinic.
Telemedicine encompasses services like virtual doctor consultations, telepsychiatry, remote therapy, and even tele-surgery where surgery is controlled remotely by an expert.
The Emergence of Telemedicine Use
Telemedicine use was made possible by a chain reaction of determinantal stimuli, with technological development taking center stage. Telemedicine had been continually evolving year after year, but the pandemic of COVID-19 accelerated its use. As clinics and hospitals became overwhelmed by the patients, the health networks were searching for a means through which they would reduce the rate of physical visitations without abandoning their patients.
Consequently, the majority of health professionals began offering virtual consultations, and patients could be treated from the comfort and safety of the home. Telemedicine consultations, for example, in America increased by over 154% in 2020 as millions of people accessed remote consultations. Telemedicine, which previously was a specialty treatment, is currently a critical part of health care.
Technological Advances Driving Telemedicine
Several technologies have been instrumental in shaping the development of telemedicine. Advances in artificial intelligence (AI), remote monitoring equipment, 5G networks, cloud computing, and electronic health record (EHR) systems have not only made remote care possible but also made it cheaper, more efficient, and more convenient.
Let us consider some of them:
- Artificial Intelligence (AI) and Machine Learning
Artificial intelligence is revolutionizing telemedicine with the possibility to enhance diagnosis, focused treatment, and enhanced patient outcomes. AI-driven solutions can potentially sift through vast quantities of medical data, from patient data to imaging studies, and support physicians in better-informed clinical decisions.
For example, chatbots driven by artificial intelligence are increasingly being utilized to conduct virtual triage, questioning patients in a series of questions to determine the severity of their symptoms before referring them to the appropriate medical specialist. AI systems can also analyze patterns in patient data, allowing doctors to diagnose disease earlier and predict possible health risks.
Besides that, AI has improved remote patient monitoring in patients with chronic conditions. Home health monitors and wearable devices can track the heart rate vital sign, blood pressure, glucose, and oxygen saturation. AI can interpret the data in real-time, notifying healthcare staff when any abnormalities need to be addressed.
- Remote Patient Monitoring (RPM) Technologies
Remote patient monitoring (RPM) refers to the utilization of devices that enable medical professionals to monitor a patient’s vital signs and health indicators from a remote location. The devices are currently an essential tool for managing patients who have chronic conditions like diabetes, hypertension, and cardiovascular disease since they enable them to be monitored around the clock without frequent visits.
Smartwatches and wearables increasingly track an assortment of health information, ranging from sleep patterns and heart rate to irregular heartbeats. The Apple Watch, for example, tracks abnormal heartbeats and alerts wearers to potential health issues. Wearables like CGMs allow diabetes patients to track blood sugar levels during the day and transfer the information to physicians for them to review.
These technologies allow patients to have more control over their conditions, and doctors can monitor progress, modify treatment plans, and intervene as needed without the necessity of scheduling office visits.
- Telehealth Platforms and Video Consultations
Video consultations are telemedicine’s defining feature nowadays, with patients now having the option to watch doctors in the comfort of their homes or even in far-flung locations. Telehealth platforms have also evolved over the years to provide secure, HIPAA-compliant video calls that can be utilized to provide real-time patient-physician interaction. Systems like Teladoc, Amwell, and Doctor on Demand offer patients the autonomy to access healthcare services at their convenience through their cell phones, laptops, or tablets.
Such telemedicine visits have been found to be beneficial for all kinds of healthcare services, from routine visits and counseling for mental illness to dermatology and even follow-up visits post-op or in the hospital. Video consults also wind up saving patients money and time as well as face-to-face facility load.
Telemedicine sites will also likely utilize electronic health records (EHR) and scheduling software as a base, so patient information and appointment making are accessible to healthcare providers.
- 5G Connectivity
5G connectivity can transform telemedicine with enhanced and more powerful connectivity for long-distance consultations, distant patient monitoring, and even tele-surgery. With considerably less delay and faster speeds, 5G enables video consults with essentially zero buffering or lag. Telemedicine with the potential to realize its full capability, especially in remote or rural locations, demands high-speed internet. With 5G, there is seamless real-time communication without fear of losing connectivity or video, enhancing the patient-provider care experience.
5G also facilitates the increased data transmission requirements of distant health devices. The delivery of high-bandwidth medical images, like MRIs and X-rays, or real-time vital signs information from remote monitoring equipment, 5G provides the bandwidth to render these services possible.
- Cloud Computing and Data Storage
Cloud computing has transformed telemedicine through secure, flexible, and affordable methods for keeping patients’ information, like medical background, lab tests, and imaging scans. Cloud computing allows different providers and specialists to access a patient’s data from anywhere globally without geography issues, making it possible to coordinate smoothly among various providers and specialists.
Cloud platforms also allow healthcare organizations to save patient data securely in massive amounts and use it at their convenience, thus avoiding delays in online consultations by handicaps in accessing data. Scalability of cloud computing also allows for simplicity in scaling capacity to meet growing numbers of patients and data as telemedicine grows.
- Blockchain for Healthcare Security
Security and confidentiality are most important in telemedicine, particularly when handling sensitive patient information. Blockchain technology offers a secure, decentralized method to hold and keep health records. With distributed ledgers and cryptographic algorithms, blockchain can offer guarantees that patient information will not be accessed or altered without consent.
Blockchain can also verify telemedicine transactions such as request for prescription, consultation, and transfer of medical records so that medical staff and patients can share information with confidence. As telemedicine increases, patient privacy and data security will be in the limelight, and one answer to protect these interests lies in blockchain.
- Virtual Reality (VR) and Augmented Reality (AR)
Virtual reality (VR) and augmented reality (AR) are utilized to enable a better telemedicine experience, such as procedure or surgery rehearsals, surgery planning, and patient rehabilitation. Telemedicine professionals can virtually rehearse surgery or procedures via simulations in VR prior to actually performing them in real life in order to sharpen their skills and reduce the likelihood of committing mistakes while performing real-life surgery.
AR is also applied to remote surgery, where the physician will remotely direct a local surgeon in a surgery through AR glasses to superimpose virtual data onto real life. Such technologies enable remote experts to offer direction for complex surgeries miles from the operating room.
In addition, VR and AR are applied in rehabilitation of patients, where they have simulated environments for physical or psychological therapy, e.g., exposure therapy for anxiety disorders.
Benefits of Telemedicine
Telemedicine holds multiple advantages for healthcare providers and patients. Among the most significant advantages include:
- Increased Accessibility
Telemedicine has increased the accessibility of healthcare, particularly for those living in rural or remote locations where healthcare services are not readily available.
