The majority of telemedicine services, most of which focus on diagnosis and clinical management, are routinely offered in industrialized regions including but not limited to the United Kingdom of Great Britain and Northern Ireland, Scandinavia, North America, and Australia. In addition, biometric measuring devices such as equipment monitoring heart rate, blood pressure, and blood glucose levels are increasingly used to remotely monitor and manage patients with acute and chronic illnesses. Some predict that telemedicine will profoundly transform healthcare delivery in the industrialized world by migrating healthcare delivery away from hospitals and clinics into homes.
In low-income countries and regions with limited infrastructure, telemedicine applications are primarily used to link healthcare providers with specialists, referral hospitals, and tertiary care centers.
