Forms of IT and e-health

There are various forms of IT and e-health in the field of medicine/healthcare and information technology, they are electronic health records, telemedicine, consumer health informatics, health knowledge management, virtual health care teams, m-health, medical research using grids, and healthcare information systems.

In electronic health records, it enables the communication of patient data between different healthcare professionals, for example specialists.

In telemedicine, physical and psychological treatments are provided to the patients from a distant location. It helps in eliminating distance barriers and can improve access to medical services that would not be consistently available in distant rural communities. It is also used to save lives in critical care and emergency situations. ÌýCyber medicine is the use of the Internet to deliver medical services, such as medical consultations and drug prescriptions. It is the successor to telemedicine, where doctors would consult and treat patients distantly through telephone or fax.

Consumer health informatics or CHI is the use of electronic resources on medical topics by healthy individuals or patients. It helps to bridge the gap between patients and health resources. Consumer Health Informatics includes technologies focused on patients as the primary users to health information. Consumer Health Informatics includes Information Resources, Communications, Remote Monitoring, Videoconferencing, and Telepresence.

In health knowledge management, an organization can get an overview of latest medical journals, best practice guidelines or epidemiological tracking which includes physician resources such as Medscape and MDLinx.

In virtual healthcare teams, it consists of healthcare professionals who collaborate and share information on patients through digital equipment for transmural care.

In m-Health, it includes the use of mobile devices in collecting aggregate and patient level health data, providing healthcare information to practitioners, researchers, and patients, real-time monitoring of patient vitals, and direct provision of care through mobile telemedicine.

Medical research using Grids is a powerful tool used for computing and data management. It is capable to handle large amounts of heterogeneous data.

Healthcare Information Systems refers to software solutions for appointment scheduling, patient data management, work schedule management and other administrative tasks in healthcare.
