Evolution of Virtual Visits and Overcoming Challenges in Remote Areas:
Examining the evolution of virtual visits, Das provides compelling statistics. Pre-pandemic, virtual visits constituted a mere 5 to 10 percent of healthcare interactions. However, with the advent of the pandemic, this figure skyrocketed to 80 percent worldwide. Post-pandemic, the numbers dipped to around 30 percent, but Das predicts a resurgence, with virtual visits expected to surpass 50 percent by 2030. The transition from an option to a necessity, particularly in the context of the hybrid care model, wherein hospitals are integrating virtual care into their services, is a key factor propelling this shift.

The integration of 5G technology is poised to play a pivotal role in overcoming the existing challenges in global telehealth accessibility. Disparities in internet access quality and technology awareness between urban and rural areas have impeded the widespread adoption of telehealth. Acknowledging telehealth as an effective solution to extend healthcare to underserved regions, the resolution of internet coverage issues and increased consumer awareness become imperative.

Addressing the challenges of extending telemedicine to remote and underserved regions, Das underscores the pivotal role of technology. The advent of 5G, advancements in cloud computing, and the integration of Artificial Intelligence (AI) have played crucial roles in overcoming barriers. Das predicts that the use of generative AI technology in digital health ventures will grow from two percent to 50 to 60 percent over the next decade. Notably, in the Middle East, 63 percent of private ventures leverage AI, indicating a higher adoption rate compared to North America and Europe. This technological leap is expected to redefine healthcare delivery, making care accessible anytime, anywhere.
