The chapter starts by examining telemedicine, a leading approach that gained prominence during the COVID-19 pandemic. Beyond simple video consultations, telemedicine has expanded to include digital triage, remote follow-ups, and access to specialists for underserved communities.

In essence, this chapter of the Digital Medicine Starter Guide operationalizes the objectives of Digital Medicine. It presents a comprehensive yet precise overview of how digital tools are transforming healthcare delivery, not as discrete solutions but as interconnected instruments within a novel paradigm.

摘要

This chapter represents a significant transition in the Digital Medicine Starter Guide, advancing from the foundational principles examined in Chap. 2 to the concrete, real-world applications that characterize Digital Medicine within contemporary clinical environments. Whereas Chap. 2 elucidated the “why”—the ethical, regulatory, and conceptual justification for digital transformation—Chap. 3 addresses the “how”: How are digital tools incorporated into workflows? How do they influence patient care? Furthermore, how do they contribute to the evolution of a proactive, precise, and participatory health system?
