These are patient records and information such as medical history, examination results, diagnoses and prescriptions, where all data is stored in electronic systems that allow quick and secure access to information.

2- Electronic Clinical Guidance: 

This application allows healthcare providers to issue prescriptions and requests for medical examinations and procedures electronically, which reduces medical errors and improves medical efficiency.

3- Electronic health administrative systems:

 It is specific to the institution itself to link departments, as well as to link the organization itself to other organizations and to all systems of health care institutions, by managing health information for patients across several health facilities, which facilitates the coordination process and thus affects the improvement of the quality of health care.

4- Smart health applications and wearable devices: 

These applications and devices provide monitoring and tracking of an individual’s health, such as heart rate and physical activity levels. This data can be stored in the cloud or on the smart devices themselves, and these applications have already proven their efficiency, success, and ability to develop for the better.

There are many storage methods:

- Regular databases: Data is stored in databases such as MySQL or PostgreSQL, and is accessed using SQL queries.

- (Cloud Storage): Online storage services such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP) provide secure and resilient storage of health data.

- (Physical Storage Systems): Data can be stored in special storage devices such as servers and local storage devices.

Point of difference:

After the widespread devastation caused by the Corona pandemic, which affected not only one country, but all countries of the world, the world’s attention turned to the digital health field, and investments in it increased in attempts to create an equal and healthy system that reduces human friction, so large parts of the health care market appeared in the United States of America. Which is worth $3.6 trillion, as it is still moving rapidly towards digital transformation, which was available before the pandemic, but attention turned to it with more careful research to find out the ideal solutions suitable for saving entire countries. Of course, it was not only the United States, but many European and Asian countries joined, according to estimates by the McKinsey Institute. Globally, global digital health revenues will rise from $350 billion recorded over the past year to $600 billion by 2024.

The other face:

Of course, there is no system without flaws, and here is the other side that we mean, as the digital care system is not integrated as we see, but it also contains other defects, which are...

- The lack of sufficient laws and legislation capable of protecting service providers, including the protection of data and information circulated related to patients, especially in small health care services institutions such as private health centers and others.

- Lack of security and privacy: 

Electronic health data can be hacked or leaked, which puts patients’ privacy at risk. Thus, the matter relates to medical health, and the matter may exceed the limits of medical risk.

- Internet outage:

 Of course, like every electronic thing, it will disappear if the network is cut off. It is not something impossible or may not happen, but the danger of what happens is a system outage, as this leads to instantaneous data loss at the time of need.

- Variation in data quality: 

The quality of electronic health data may vary from one institution to another, which may affect the accuracy of diagnosing patients and providing appropriate health care.

- Excessive dependency on technology: 

Doctors and health providers may rely heavily on electronic systems, which may lead to a loss of the ability to work effectively in the event of technical problems.

- Cost:

 E-health technology can be expensive to implement and maintain, especially for small and medium enterprises.

- Regulatory and legal difficulties: 

Health institutions may face challenges in complying with regulations and legislation related to e-health, which can affect their operations and applications.

- Lack of human communication:

 Excessive dependence in this case may lead to a lack of communication and thus may affect the health care process.

- Concern about job loss: 

Technological advances in e-health can raise concern about the loss of some traditional jobs in health care, especially jobs that require non-technical skills.

We can say that like everything, it contains both positive and negative aspects, and of course all defects can be overcome with some treatments to overcome them, as we realize that the matter is inevitable from our reality and from the development of technology and its interference in all of our lives.
