Abstract: In response to the global shift in healthcare delivery due to the COVID-19 pandemic, this study investigates the adoption of telehealth technologies and assesses their long-term sustainability within new public health paradigms. Telehealth, accelerated by the pandemic's demands, offers a unique perspective on evolving healthcare delivery methods that emphasize accessibility and efficiency. By employing a mixed-methods approach, which synthesizes quantitative data with qualitative insights from various stakeholders, this research evaluates how telehealth has enhanced the delivery of medical services, especially in remote and underserved communities. Despite challenges related to technological infrastructure and regulatory constraints, our analysis of revenue models and cost-benefit evaluations suggests that telehealth is economically feasible and possesses significant market potential. The findings advocate for robust policy support and technological investment to enhance global telehealth accessibility and implementation. Additionally, the study highlights the necessity of expanding educational training for healthcare professionals to effectively adapt to telehealth systems. These strategic measures are pivotal for promoting the widespread application and sustainable development of telehealth, positioning it as a cornerstone in the future landscape of global healthcare. Continued research is recommended to further refine telehealth models and develop comprehensive frameworks that address emerging healthcare challenges and disparities.
