Telehealth can be defined as: “The use of information and communications technology (ICT) to deliver health services and exchange health information when distance separates the participants” (Elford 1998: 207). Telehealth is healthcare at a distance. The aviation and aerospace environment in particular can be considered the ultimate in providing telehealth services as the patients, that is, astronauts, can be extremely far away. Healthcare team communications are impacted by the use of telehealth in a number of ways. Much can be learned from telehealth experiences because telehealth involves not just technology, but health professionals who use, operate, and interact with the technology. When implemented properly, telehealth can enhance communications between healthcare professionals.
