2. eHealth
• eHealth, or electronic health, refers to the use of
digital technology and telecommunications to
improve and manage health services and
information.
• It encompasses a wide range of applications and
tools that leverage technology to enhance healthcare
delivery, patient engagement, and health data
management.

3. Key Aspects of eHealth
• Telemedicine and Telehealth: These involve remote
consultations and services using video calls, phone
calls, or messaging.
• Telemedicine allows patients to receive medical advice
and care without needing to visit a healthcare facility
physically.
• Electronic Health Records (EHRs): Digital records
that store a patient's health history, including diagnoses,
treatments, medications, and test results.
• EHRs facilitate easy sharing of information among
healthcare providers, improving coordination and
continuity of care.

4. Key Aspects of eHealth
• Health Information Systems: Systems that manage and
analyze health data, including patient management systems,
laboratory information systems, and pharmacy information
systems.
• Mobile Health (mHealth): Health-related services and
information delivered through mobile devices such as smart
phones and tablets. This includes health apps for monitoring
health metrics, managing chronic conditions, and accessing
health information.
• Wearable Health Technology: Devices like smart watches
or fitness trackers that monitor various health metrics (e.g.,
heart rate, physical activity) and provide real-time feedback
to users and healthcare providers.

5. Key Aspects of eHealth
• Personal Health Records (PHRs): Digital
records that individuals can manage themselves,
allowing them to track their health information
and share it with healthcare providers when
needed.
• Health Analytics and Big Data: Using data
analytics and machine learning to interpret large
volumes of health data, which can lead to better
decision-making, predictive modelling, and
personalized medicine.

6. Key Aspects of eHealth
• Patient Portals: Online platforms that allow
patients to access their health information,
communicate with their healthcare providers,
and manage appointments and prescriptions.
• Artificial Intelligence and Machine
Learning: AI-driven tools that assist in
diagnostics, treatment planning, and
personalized medicine by analyzing health
data and predicting outcomes.

7. Benefits of eHealth
• Improved Access to Care: eHealth technologies can extend
healthcare services to remote or underserved areas, making
it easier for patients to access care.
• Enhanced Patient Engagement: Tools like mobile apps
and patient portals empower patients to take an active role
in their health management and stay informed about their
conditions.
• Increased Efficiency: Digital records and health
information systems streamline administrative processes,
reduce paperwork, and improve the efficiency of healthcare
delivery.
• Better Coordination of Care: EHRs and other digital tools
facilitate better communication among healthcare providers,
leading to more coordinated and integrated care.

8. Benefits of eHealth
• Cost Savings: By reducing the need for physical
appointments, minimizing duplication of tests, and
streamlining administrative processes, eHealth can help
lower healthcare costs.
• Data-Driven Insights: Health analytics can uncover
trends, identify potential health risks, and guide public
health interventions and policy-making.
• Real-Time Monitoring: Wearable devices and remote
monitoring tools enable continuous tracking of health
metrics, which can be crucial for managing chronic
conditions and detecting issues early.
• Personalized Medicine: Access to comprehensive data
allows for more tailored and individualized treatment
plans based on a patient’s unique health profile.

9. Challenges of eHealth
• Data Security and Privacy: Protecting sensitive health information
from breaches and unauthorized access is a significant concern.
• Integration and Interoperability: Ensuring that different eHealth
systems and devices can communicate and work together effectively.
• Digital Divide: Addressing disparities in access to technology and
digital literacy, especially in low-income or rural areas.
• Regulatory Compliance: Navigating complex regulations and
standards related to health data and telemedicine practices.
• Overall, eHealth represents a transformative shift in how healthcare
is delivered and managed, with the potential to improve outcomes
and enhance the overall patient experience.
