Telemedicine: a green prescription for ASEAN's healthcare future

With growing healthcare demands and the pressing need for sustainable practices, Southeast Asia is at a turning point in its healthcare development. With its potential to decarbonise healthcare delivery, maximise resource use, increase access to treatment, and support proactive, sustainable healthcare models, telemedicine emerges as a game-changing answer. With a focus on Singapore's leadership position and the significance of regional cooperation and contextualised implementation, this essay examines how telemedicine might propel ASEAN's sustainability shift. ASEAN can create an efficient and ecologically conscious healthcare system in the future by embracing telemedicine.

A confluence of possibilities and challenges is causing a significant upheaval in the ASEAN healthcare sector. Traditional healthcare systems are under tremendous strain due to the increased prevalence of chronic diseases, rapid population expansion, and the constant threat of pandemics. At the same time, there is no denying the pressing need for sustainable methods in all fields, including healthcare. In this ever-changing landscape, telemedicine not only becomes a solution to these problems but also a key component of ASEAN's regional sustainability shift.

The imperative for sustainable healthcare in ASEAN
ASEAN's pursuit of universal health coverage intersects with an urgent global imperative: environmental sustainability. The region's healthcare systems are not only grappling with the traditional pressures of population growth, rising chronic diseases, and pandemic preparedness, but also the increasing environmental burden of healthcare delivery. This necessitates a shift towards sustainable healthcare practices, where resource optimisation, reduced emissions, and equitable access are paramount. In this context, telemedicine emerges as a critical enabler of ASEAN's sustainability pivot, offering a pathway to reimagine healthcare delivery while minimising its environmental footprint.

ASEAN's healthcare systems face a complex interplay of pressures:

• Population growth and resource strain: Healthcare resources in ASEAN are severely strained by the region's growing population. Common issues include overcrowded hospitals, lengthy wait times, and a lack of medical workers, especially in specialised sectors. Sustainable methods are essential since this strain increases resource consumption and environmental impact.

• Chronic diseases and environmental burden: Chronic diseases like diabetes, heart disease, and cancer are becoming more common and need to be managed continuously, which puts a significant strain on healthcare systems and lowers economic productivity. Traditional methods of controlling these conditions have a substantial negative environmental impact, underscoring the need for sustainable solutions.

• Pandemic preparedness and resilient systems: The COVID-19 pandemic highlighted the need for resilient and flexible care approaches and revealed weaknesses in healthcare systems. It also emphasised how crucial it is to minimise the negative effects of healthcare delivery on the environment, especially during outbreaks, and to cut down on needless physical contact.

• Healthcare disparities and equitable access: Sustainable development is hampered and health disparities are made worse by unequal access to high-quality healthcare throughout ASEAN, especially in underserved and rural areas. In order to close these disparities and advance fair access to care, telemedicine can be extremely important.

Why telemedicine is indispensable for ASEAN's sustainability pivot

Telemedicine offers a compelling pathway towards a more sustainable and resilient healthcare system in ASEAN:

• Decarbonising healthcare: Telemedicine dramatically lowers transportation-related carbon emissions by eliminating the need for travel to medical facilities. This is especially important in ASEAN, where air pollution and traffic congestion are big issues in cities. According to a UK study, telemedicine has the potential to have a major environmental impact by reducing carbon emissions by up to 30% when compared to in-person consultations.

• Optimising resource utilisation: By eliminating the need for physical infrastructure and allowing medical professionals to visit more patients more quickly, telemedicine maximises resource utilisation. This may result in less waste production, less energy use, and less dependency on healthcare facilities that need a lot of resources.

• Expanding access and reducing inequality: Patients no longer need to travel great distances for care thanks to telemedicine, which may fill healthcare shortages in underdeveloped and remote areas. In addition to improving health outcomes, this also lessens the environmental effect of travel and encourages fair access to medical care.

• Promoting proactive, sustainable care: By enabling preventative management of chronic illnesses, telemedicine may lessen the need for emergency care and hospital stays, which are costly and have a big environmental impact. Telemedicine can help create a more sustainable and preventative healthcare model by giving patients the ability to monitor their health from a distance.

• Strengthening pandemic resilience: Rapid response to public health emergencies is made possible via telemedicine, which also lessens the environmental effect of healthcare delivery during outbreaks and the requirement for physical interaction. Building robust healthcare systems in ASEAN, which is susceptible to newly developing infectious illnesses, requires this.

Singapore's leadership in sustainable telemedicine

Singapore is uniquely positioned to champion sustainable telemedicine in ASEAN due to:

• World-class healthcare system: With its strong emphasis on innovation and technology, Singapore's well-known healthcare system offers a great platform for creating and deploying long-term telemedicine solutions.
