Effectiveness of Telemedicine in Disaster Relief Response Management

Breaking down the chosen subject we must be clear about what telemedicine is and what exactly the disasters are being referred to. Telemedicine refers to the use of digital means of communication to provide healthcare services and consultations without the physical presence of any medical staff. A disaster is an event, whether man-made or natural, that disrupts the normal course of daily activities. It can range from harm to ecosystems and loss of life to impairment of households and essential facilities. It also includes pandemics and epidemics.Now, shifting our focus to the history and evolution of telemedicine, we can trace its initial and rudimentary usage back to the 1800s. It was around this period the telephone was invented and medical professionals started to explore its usage for treatment. Dr. Bird used the term to describe the use of television to provide medical consultations and services over a distance. When telemedicine was first implemented is very vague but the first documented use of telemedicine to provide direct patient care occurred in 1967 at Boston’s Logan International Airport. In the 1920s and 30s medical propaganda was spread through radio, spreading awareness about public health. The U.S. space program was also critical in the evolution of telemedicine. National Aeronautics and Space Administration (NASA) implemented telemedicine to monitor the astronauts’ health and vital signs.

In India, telemedicine started taking shape in the late 1980s and early 1990s. The first telemedicine network was launched by The Apollo Hospitals Group in Chennai. In 2005, ISRO collaborated with Apollo Hospitals to create a national telemedicine network known as ISRO’s SEHAT project. Private medical organizations made it possible for patients to consult doctors over online platforms and video calls. In 2014, the Indian government recognized the vast advantages of telemedicine and launched the National Telemedicine Program. It had the aim to improve access to healthcare in rural and undeveloped areas, it connected various medical colleges and institutions throughout the country.After 2019, the use of telemedicine saw a sudden surge in its usage due to the unprecedented conditions caused by COVID-19.Amidst lockdowns and social distancing, telemedicine emerged as a crucial resource. We can see a general overview of the structure of telemedicine in Fig. 1, it shows the various components and their parts.

Broadly classifying, telemedicine falls into two categories: Synchronous and Asynchronous. In synchronous telemedicine, there is live and real-time interaction between the patient and the medical professional via online platforms. Asynchronous telemedicine involves either virtual interaction or the patient uploading their health report, and a doctor reviews and diagnoses the patient later. Telemedicine can be more specifically categorized as store-and-forward, remote monitoring, and real-time interactive services.

Store-and-forward telemedicine involves the patient data and health reports being sent to the healthcare professionals who review them later. This falls under the branch of asynchronous telemedicine and is used vastly in radiology and dermatology. Typically, these cases are not severe and do not need immediate medical attention. Store-and-forward telemedicine enhances flexible scheduling and collaboration between experts leading to a more accurate outcome.

Remote monitoring plays a significant role in various healthcare domains, including chronic disease management, pre-operative, and post-operative care, as well as remote rehabilitation and physical therapy. For instance, in pre-operative care, involves educating the patient about the upcoming procedure, conducting a preoperative health assessment, and assessing health information and risks by reviewing previous health records.

Real-time interactive services involve the usage of telemedicine platforms, video conferences, integrated Electronic Health Records (EHR), and connected wearable medical devices to facilitate immediate and interactive communication between the patient and medical professionals. These services are employed when urgent care is required, during post-operative procedures, or for discussions related to health reports and diagnostics.

The demand for telemedicine has been growing steadily since the last decade and saw a sudden rise after the advent of COVID-19. Several reasons contribute to the high demand for telemedicine, some of which are listed below:

1. It removes barriers such as physical distance and makes medical facilities accessible in remote areas too.
2. The mass availability of internet connections and smart devices facilitates communication between patients and healthcare departments.
3. It minimizes expense by removing variables of travel, and time spent. Also due to the nature of some services being delivered remotely, it cuts down on operational costs.
4. It allows flexible scheduling both on the doctor’s and patient’s end.
5. Government policies and insurance coverage of expenses incurred due to online consultations help encourage the public to use it more.
6. It also reduces the strain on healthcare facilities, as minor inconveniences can be diagnosed online, keeping the infrastructure free for people who need immediate help or are in critical situations.

With the continuous advancement in technology, telemedicine is deemed to play a crucial role in the healthcare sector.

Despite the rapid growth in technology, we cannot say the fruits of telemedicine are available everywhere. Many factors hinder its availability, and some of those are as follows:

1. Limited access to technology and the internet remains a significant challenge. There is still a scarcity of internet access in rural areas, limiting the means to communicate with medical professionals. Network connectivity and technical glitches are still a recurring problem.
2. In India, there are nearly 780 spoken languages, and this diversity may lead to a language barrier between the patient and the call recipient. Thus, effective communication can be challenging to implement.
3. The absence of necessary technologies in hospitals to enable remote healthcare is still a massive setback.
4. Limited insurance coverage and high rates set by the hospital for e-consultations can discourage people from participating in them.
5. There are still many people unaware that the hospitals they regularly visit offer online consultations as an option. Thus, we need measures to educate the public about telemedicine and its advantages.
6. Telemedicine has its limitations; the inability for physical diagnosis can lead to some inaccuracies or result in certain symptoms being overlooked as they are not as prominent.

AI and Machine Learning in Telemedicine: Continued integration of artificial intelligence (AI) and machine learning (ML) is expected to improve its diagnostic capabilities by leaps and bounds. These technologies can analyze vast amounts of patient data, identify patterns, and assist healthcare providers in making more accurate and timely decisions. Predictive analytics can be used to predict potential health issues from symptoms, allowing preventive and personalized treatment plans.

Virtual and Augmented Reality (VR/AR): VR and AR technologies hold the most potential in revolutionizing the industry, from being present with the patient in AR to efficient training of professionals to tackle disasters it is going to be extremely helpful. It can simulate the conditions of a disaster so that rescue teams can train on it and find the shortest way to tackle it.

Remote Patient Monitoring (RPM):

Wearable devices and IoT sensors will become more sophisticated and advanced, enabling continuous monitoring of vital signs and chronic conditions. RPM can encourage patients to regularly participate in their healthcare routine, fostering a more preventative and patient-centric approach.

5G Technology: The ongoing spread of 5G networks will significantly improve the speed and reliability of internet connections, enabling high-quality, real-time video consultations. This will enhance the patient-doctor communication experience. It will also be important in areas of telesurgery.

Telemedicine Regulations:

Governments and healthcare regulatory bodies are likely to add more laws and refine the existing ones so that more people are encouraged to use them. Standardization of telemedicine practices will be one of the key focuses such that all areas receive the same care without any discrepancies.

Integration with EHR: Seamless integration with Electronic Health Records (EHR) systems will become more prevalent, it will ensure the patient’s medical history will be transparent before the doctor before treatment so they can adjust according to it. It would also remove the burden of manual indexing of these reports.

Expanded Access to Specialized Care:

Telemedicine will allow specialists to refer to each other, allowing them to remotely consult on complex cases and provide expertise to healthcare professionals in areas they might be lacking. This can help in addressing regional disparities in healthcare services.

Mental Health Telemedicine:

The integration of mental health services into telemedicine platforms will see continuous growth due to the increasing demand for mental healthcare. AI-driven mental health apps and virtual therapy sessions may become more sophisticated and personalized.

Global Telemedicine Adoption:

As telemedicine proves its value, its adoption will likely expand globally, especially in regions where healthcare infrastructure is limited. Crossborder telehealth services may become more common, allowing patients to access expertise from around the world.

Effective deployment of the vast array of supplies offered by telemedicine proves irreplaceable in disaster relief. It offers swift access to medical knowledge and expertise. Through this platform, medical professionals can diagnose areas that have been struck by severe calamities and are unreachable either due to physical barriers or hazardous conditions. For example, it allows us to help people who were victims of earthquakes or landslides, where reaching the impacted area can be extremely time-consuming or dangerous. It also is important in cases of a pandemic where immediate medical attention is required but physical presence will help spread it. We can already see how important it is as it overcomes physical barriers with such ease.

It facilitates efficient and just distribution of resources that are out of physical reach and addresses the specific demands of that area. It also can help in the mental health aspect. The psychological trauma induced by severe disasters can be reduced via counseling and mental health support.

In the aftermath, telemedicine is used for patient monitoring and recovery assessment. Notes are taken on the current situation to devise ways to resolve it faster if such conditions prevail again.

The proposed model for the critical response to be taken in order to ensure maximum survival is illustrated in Fig. 2.

Disaster Event: This is the first step in disaster management, it is focused on identifying the nature of the disaster, how severe it is and how much geological area has it affected.

Telemedicine Triggered: This indicates that telemedicine services are activated to deliver healthcare facilities. It ensures to creation of a seamless connection between the site of disaster and medical professionals for quick and easy diagnosis.

Communication and Triage: Effective communication is pivotal in handling any kind of disaster. The cases are classified into five categories based on their severity. They are Immediate, these cases need the most urgent care. Delayed cases have significant cause for attention but are not life-threatening [10]-​[12]. The minimal category can safely wait for treatment as they have mostly minor injuries. The expectant category is for those whose survival is unlikely even after all possible help is provided. Patients under re-evaluation are those whose conditions or symptoms are not certain and require further assessment.

Remote Consultation: This consists of either video conferences or phone calls/ radios to initiate communication with the hospitals so that the patients can be diagnosed and told what to do ahead [13]-​[15]. It ensures the availability of services to those have limited physical access to medical facilities.

Medical Support Teams: Remote medical teams are deployed on-site to tackle the problems that are not possible to be handled by the citizens. They take resources and provide real-time guidance also they provide advice to the local healthcare facilities that might not be versed in how to tackle the situation.

Resource Deployment: The efficient and impartial distribution of medical resources and such is extremely crucial to handling the situation. It has the goal to optimize the available resources and address the demands of the citizens [16]-​[17].

Monitoring: Continuous monitoring is a critical response strategy to tackle the disaster. Remote sensing technologies such as sensors and drones are used to their full extent to keep updating the healthcare facilities on how the situation is so they can keep updating ways to resolve it efficiently.

Recovery Assessment: At the end of the model the on-site professionals will survey the impact of the disaster, identify the remaining needs of the people, and devise strategies to be helpful in the long run.

Resolved: This state shows that the disaster has passed and was handled successfully. A complete review of the entire process is done, so that it can be worked upon and improved for future cases.

Following the proposed model step-by-step is likely to increase the survivability rate in disasters.
