Referring to health information services, health care education, and health care services in a broad sense, the term telehealth is an all-encompassing one. In fact, telecare and telemedicine are generally covered within the broader scope of the term telehealth. Examples of telehealth includes health education services, remote monitoring of vital signs, ECG or blood pressure and remote doctor-patient consultations (telemedicine). Telehealth technology enables the remote diagnoses and evaluation of patients in addition to the ability to remote detection of fluctuations in the medical condition of the patient at home so that the medications or the specific therapy can be altered accordingly. It also allows for e-prescribe medications and remotely prescribed treatments.
Telecare is the term that relates to technology that enables patients to maintain their independence and safety while remaining in their own homes. This technology includes mobile monitoring devices, medical alert systems, and telecommunications technology like computers and telephones. Continuous remote monitoring of patients enables telecare to track lifestyle changes over time as well as receiving alerts relating to real-time emergencies.
This term has a narrower scope than that of telehealth. It refers more specifically to education over a distance and the provision of health care services through the use of telecommunications technology. Telemedicine refers to the use of information technologies and electronic communications to provide remote clinical services to patients. The digital transmission of medical imaging, remote medical diagnosis and evaluations, and video consultations with specialists are all examples of telemedicine.
