With the booming popularity of internet-based healthcare, numerous new medical concepts have emerged. In addition to mHealth, which VCBeat has previously introduced,Click here for details), eHealth is also one of them, and it is a term with a very broad concept and intense debate over its definition.
What is eHealth?
eHealth, commonly referred to as “smart healthcare,” is a relatively new term in the medical field. It has a broad meaning, referring to the large-scale application of electronic information and communication technologies in the healthcare process.
eHealth encompasses a broad range of domains, leading to significant controversy over its precise definition within the internet healthcare sector. Meanwhile, eHealth is often used as a synonym for Health IT. However, definitions of eHealth vary across different institutions. VCBeat lists several common definitions of eHealth below:
The Journal of Medical Internet Research defines eHealth as:
Medical Information, an Emerging Field in Public Healthcare"Medical information," an emerging field within public healthcare, refers to the provision or enhancement of medical information and services through the Internet or related technologies. In a broader sense, this term encompasses not only the development of health information technology but also embodies a globalized, Internet-oriented mindset, approach, and attitude, aimed at leveraging information and communication technologies to advance the healthcare sector.
The World Health Organization defines eHealth as:
The safe and efficient use of information and communication technologies to better promote health and related fields, such as healthcare, health monitoring, health education, and research.
The European Union defines eHealth as:
Leveraging advanced information and communication technologies to meet the needs of the general public, patients, healthcare workers, physicians, and health policy makers.
Based on various definitions of eHealth, VCBeat believes that the main components of eHealth include:
Electronic Medical Records (EMR/EHR) (For details, click here.)
Telehealth/telemedicine (For details, click here.)
Medical Information System
Consumer Health Data
Virtual Healthcare
Mobile Health (mHealth) (For details, click here)
Big Data Systems in the Healthcare Sector

How Is eHealth Applied?
Given the extensive penetration of information and communication technologies in the healthcare sector, the application potential of eHealth is virtually limitless. Some of the more widespread applications include:
Electronic medical records (including EMR and EHR), electronic prescriptions, clinical information management systems, digital image storage systems, etc.;
Telemedicine and telemedicine systems enable the remote transmission of diagnostic and treatment information and remote consultations, effectively reducing healthcare costs and improving therapeutic outcomes;
Utilization of consumer information, including the vast amount of data from numerous health and medical websites and increasingly popular mobile health apps;
Clinical Information Management System, including radiology and nursing information systems, computer-aided diagnosis and treatment, digital medical imaging, as well as surgical planning and training, enabling surgeons to provide more precise diagnoses and treatments;
Specialized eHealth systems used by researchers for the collection and analysis of public health information, such as research projects on infectious diseases, drug development, and outcomes analysis;
eHealth tools that provide support for medical information, such as pharmaceutical supply chain management, appointment registration systems, payment systems, hospital administration and management systems, and other clinical decision support;
Overall, eHealth has effectively enhanced transparency and accountability in healthcare processes while promoting multidisciplinary integration. Furthermore, eHealth helps overcome geographical barriers and patient-specific obstacles, thereby improving the delivery of medical services. It also reduces medical errors and strengthens evidence-based medicine by increasing diagnostic and therapeutic precision. By streamlining workflows, boosting efficiency, and reducing wait times and waste, eHealth enables more efficient utilization of healthcare resources.
Current Market and Development Trends in eHealth
Estimates of the eHealth market size are largely determined by its definition. According to a market report by GSMA, the global eHealth market is projected to grow from $96 billion in 2010 to $160 billion in 2015, with an average annual growth rate ranging between 12% and 16%.
Factors Driving the Growth of the eHealth Market Include:
Out-of-hospital patients’ emphasis on and participation in internet-based healthcare;
Increased awareness and acceptance among healthcare professionals;
Demonstration of the Effectiveness of eHealth Technologies;
A favorable regulatory environment and improved support for interoperability;
Pressure to reduce healthcare costs;
Population aging and the rising incidence of chronic diseases;
Factors Hindering the Development of the eHealth Market Include:
Resistance within the healthcare system;
Insufficient evidence for the effectiveness of certain eHealth approaches;
Complexity of eHealth Systems;
Lack of supporting infrastructure;
The costs of related technologies and equipment are excessively high;
Excessive maintenance and service costs;
Interoperability issues;
Concerns Regarding Privacy and Security Regulation;
Lack of professionals with relevant expertise
Lack of standard medical service agreements;
Lack of budget and investment in relevant fields;
In fact, regardless of the specific definition of eHealth, its impact on and transformation of the global healthcare sector are undeniable. As its value to patients, physicians, and healthcare systems is further demonstrated, this broad concept within the realm of internet-based healthcare will exert a more profound influence on global healthcare reform.
