The 150-year history of long-range medical treatment, from science fiction to telemedicine

The fascinating history of telemedicine stretches back over 150 years, drawing inspiration from science fiction and advancing in tandem with real-world technology. In 1874, a surgeon in South Australia sent wound care instructions through the telegraph to a patient located 2,000 kilometers away, while a medical journal proposed the utilization of telephones to reduce unnecessary patient visits in 1879.

The concept of telemedicine sparked the imagination of science fiction writers, who envision new ways to treat patients across vast distances. British novelist EM Forster depicted telemedicine apparatus descending from ceilings in his 1909 short story "The Machine Stops," providing in-home care when telegraphed. Forster's narrative also introduced concepts such as instant messaging and an embryonic internet, which are vital components of modern telemedicine.

In 1924, Radio News magazine featured a cover story showcasing the prospective "Radio Doctor." Although the content was more fiction than reality, depicting a physician examining a patient through a screen, the imagery inspired possibilities. Likewise, US writer Hugo Gernsback described "The Teledactyl" in his 1925 Science and Invention cover story. This device facilitated doctor-patient interaction through radio transmitters and television screens, enabling physicians to remotely touch patients using a mechanically controlled hand. Gernsback, an influential pioneer in radio and electrical engineering, played a significant role in establishing science fiction as a literary genre.

The radio emerged as a vital tool for early telemedicine, especially concerning medical consultations for seafarers and passengers in the 1920s. Consequently, physicians could evaluate, diagnose, treat, and provide medical advice through radio communication, a practice that continues today for medical consultation on ships at sea.

Gernsback revisited distance medicine in 1955 with "The Teledoctor," a fictional device employing telephones, closed-circuit television, and mechanical arms controlled by physicians to offer remote patient care. The concept gained further traction when psychiatrists in Nebraska leveraged closed-circuit televisions for conducting psychiatric consultations in 1959.

NASA played a significant role in integrating telemedicine into space exploration throughout the 1960s and beyond. By 1971, the Space Technology Applied to Rural Papago Advanced Healthcare (STARPAHC) program utilized a telemedicine system, connecting Tohono Oʼodham individuals with healthcare professionals remotely. This program employed two-way television, radio connections, and remote telemetry to bridge vast distances.

The term "telemedicine" was officially coined in 1970, and its adoption experienced increased momentum from the 1970s onwards. The rise of the internet in 1983 revolutionized telemedicine, bringing new possibilities for connecting patients and physicians. Satellites have also played a crucial role, enabling communication across greater distances without the need for costly two-way closed-circuit televisions. The decreased costs of developing and maintaining telemedicine networks in the 1980s led to more widespread adoption.

Science fiction continued to influence the future of telemedicine, with Canadian writer Peter Watts envisioning the "Medical Mantis" in his 1999 novel, "Starfish." This device allowed physicians to remotely examine and perform procedures on patients in the depths of the ocean. In the early 2000s, NASA's Extreme Environment Mission Operations even tested teleoperated surgical robots in undersea environments.

Telemedicine witnessed relatively limited utilization until the global COVID-19 pandemic, which propelled its widespread adoption as an integral aspect of modern healthcare. Video consultations have become commonplace, bridging the gap between physician and patient, though so far without the robotic capabilities imagined by Gernsback.

Future advances in telemedicine may be fueled by developments in human spaceflight. As space exploration progresses, the monitoring of astronauts' health from Earth will necessitate groundbreaking technological advancements to keep pace with voyages into the depths of space. With each stride forward, telemedicine continues to evolve, often matching the manifestations of science fiction envisioned decades ago.
