E-health refers to health services and information delivered through the internet and related technologies. It aims to promote health, well-being, and enhance professional practice through using information management and communication technology. E-health is about finding, using, recording, managing, and transmitting health information to support patient care decisions. While technology enables this, e-health is more than just the use of computers and devices. Potential benefits include improved patient safety, communication, efficiency and care coordination through electronic health records. However, concerns include the high costs and training needs, as well as risks to security and privacy of personal health information stored electronically.

2. E-Health is an emerging field in the
intersection of medical informatics,
clinical practice, public health, and
business, referring to health services
and information delivered or
enhanced through the Internet and
related technologies.

3. The RCN defines eHealth (sometimes called
digital health) as concerned with promoting,
empowering and facilitating health and wellbeing
with individuals, families and communities, and
the enhancement of professional practice through
the use of information management and
information and communication technology (ICT).

4. There is more to eHealth than just
technology. It is about finding, using,
recording, managing, and transmitting
information to support health care, in
particular to make decisions about patient
care. Computers (and other ICT devices) are
merely the technology that enables this to
happen.

5. Also e-health refers to various and
information and services that is either
shared or modified through technology
such as the internet.The term itself
emerged in the year 2000. It includes
virtually all of the aspects associated with
medical informatics but also sets the main
focus around sending clinical data.

6. •Telemedicine
•EMR(Electronic Medical
Record)
•Health informatics
•Evidence base medicine

8. • An increase in patient safety through a reduction in medical
and clinical adverse events
• Improved communications between the patient and the carer
• Reduction in length of stay due to improved operational
efficiency
• Rapid intervention during critical periods of care facilitated by
real time alerts and reminders
• Improved medications management
• Access to modern day electronic media and social information

9. • A work environment attractive to care providers
• Reduction in transcription, legibility and omission errors
• Enhanced ability for clinicians to coordinate care
because of simultaneous access to the electronic record
• Reduced time locating/collecting patient information
• Decreased number of avoidable clinical incidents
• Reduction in the number of unnecessary administrative
tasks, meaning clinicians will have more time to
communicate with patients about their care and needs

11. • With eHealth system, patients can schedule their appointment with healthcare professional online
through healthcare portal. It can save time, cost and extra efforts of patients in an effective manner, as
patients do not have to move from their home as they will be able to arrange an online consultation
service.
• Electronic health data will provide people with clear and more insight into their health. As per their
wish, they can even share their health-related information with anyone with just a few clicks (Botha,
Botha & Herselman, 2014). Along with these, they will get an account in which, all health-related
information will be stored which can be easily be accessed at any time and from any location. So,
people do not have to carry their medical reports everywhere.
• Doctors have to do less paperwork, as everything will go online. They will be able to share the
information among other colleagues in an easy and secure manner.
• At the point of care, doctors would be able to get accurate and complete information about the
patients and their' medical history.
• Doctors and patients would be able to share the information among other clinicians and caretakers.
• Privacy and security of eHealth records will be enhanced in an effective manner.
• E-Health system will help providers to improve quality, productivity, and work-life balance.

13. • One of the main disadvantages of the eHealth system is that it is time and cost consuming. The start-
up cost of this system is too high
• As all the health-related data of people will store on electronic databases then it might be vulnerable
to several cyber-attacks such as denial of service attacks, phishing attack, malware attacks etc.
• Security and privacy of each person will be on a stake, as they feel their data might get a breach.
• Special training of electronic medical records will be required for people. Along with this, the software
will add additional expense in paying people to take training (ELLIOTT et al., 2012).
• Due to the instantaneous nature of eHealth records, electronic health records must be updated
immediately after the patients’ visit. If this not happens then the next doctor will rely on inaccurate
data for treatment protocols.
• People will more get panic whenever they get a false alarm or misinterpret a file entry.
• There are several liability issues are there with Electronic Health Records implementation. For example,
medical records may get destroyed or lost during the transition from a paper-based system to an
electronic-based system which could lead to inappropriate treatment (J Johnson III, 2016).
