What is eHealth?

eHealth refers to the use of digital technologies—such as the internet, mobile apps, wearables, and electronic health records (EHRs)—to manage and improve healthcare services. The term encompasses a broad range of health services that are delivered or supported through electronic means. eHealth solutions are designed to improve both the quality and efficiency of healthcare by facilitating better communication, information sharing, and patient engagement.

Key components of eHealth include:

1. Electronic Health Records (EHRs): Digital versions of patients’ paper charts that contain comprehensive health information, such as medical history, diagnoses, treatments, medications, and test results. EHRs can be accessed by healthcare providers in real-time, improving coordination and continuity of care.
2. Mobile Health (mHealth): The use of mobile devices (smartphones, tablets, etc.) and apps to track health data, monitor chronic conditions, and communicate with healthcare providers. Examples include apps that help track fitness, medication adherence, or mental health.
3. Health Information Systems: Digital tools that manage patient data, appointments, billing, and more. These systems are used by healthcare organizations to streamline administrative tasks and improve patient care.
4. Personal Health Records (PHRs): Similar to EHRs, but managed by the patients themselves. These allow individuals to track and manage their own health data, such as medical history, vaccinations, and lab results.
5. Remote Monitoring: Devices like wearables, sensors, and home health equipment that collect health data in real-time, which is then transmitted to healthcare providers for monitoring and early intervention.

What is Telemedicine?

Telemedicine refers to the practice of providing medical care remotely through digital platforms, allowing patients to consult with healthcare providers without being physically present in a healthcare facility. Telemedicine is a subset of telehealth, which includes a broader range of remote health services, such as health education and administrative meetings.

Telemedicine services are typically delivered through video consultations, phone calls, or online messaging. It is especially valuable in situations where patients have limited access to healthcare services, such as in rural areas or during emergencies (e.g., the COVID-19 pandemic).

Key types of telemedicine services include:

1. Video Consultations: Virtual doctor visits where patients can see and speak with a healthcare provider using video conferencing technology. This is particularly useful for non-emergency consultations, follow-ups, or routine check-ups.
2. Remote Monitoring: As part of telemedicine, remote monitoring tools collect data on patients’ health (e.g., heart rate, blood pressure, glucose levels) and send it to healthcare providers. This allows providers to track patients’ health remotely and intervene if necessary.
3. Store-and-Forward Telemedicine: This model allows patients to send medical images (e.g., X-rays, MRIs) or other health data to a healthcare provider, who can review and provide a diagnosis without the need for a live consultation. This is often used in specialties like dermatology, radiology, and pathology.
4. Asynchronous Communication: This includes online messaging or email consultations where patients can ask questions or report symptoms to their healthcare provider, who responds at a later time.
