Internet Healthcare Terminology Decoded: EHR, EMR, and PHR – Overview and Product Insights
One of the most significant innovations that internet healthcare has brought to the current medical system is the digitization of medical data and information, with “Electronic Medical Records” (EMR) being the most intuitive representation. In many developed Western countries, EMR systems have already become highly mature. For instance, the UK’s National Health Service (NHS) has effectively leveraged the advantages of EMRs to implement electronic referrals and plans to gradually achieve paperless hospitals. VCBeat has previously published numerous articles discussing electronic medical records. So, what terms have you heard in relation to “electronic medical records”? EHR, EMR, or PHR? Do you find them confusing? What exactly are the differences among these three, and how are they related? VCBeat provides detailed answers below.
What Are PHR/EHR/EMR?
EHR, which stands for Electronic Health Record, refers to a longitudinal electronic health information collection system for patients, capable of recording data generated by patients across all healthcare institutions. This digitally stored information needs to be shareable among different healthcare institutions, so that patients can receive quality medical services when consulting different doctors, hospitals, clinics, or even in different countries. It also enables physicians, other healthcare providers, and insurance companies to share the patient’s medical records across different devices. VCBeat has previously published articles highlighting the necessity of using EHRs (Click here for details）。
EHRs need to include various types of patient data and information, such as:
Patient Demographics
Medical History
Medication and Allergy History
Immune Status
Laboratory Test Results
Radiographic Images (e.g., X-rays)
Vital Signs
Personal data, such as age, height, and weight
Medical process records and details of issues, etc.
Payment Information
EMR, short for Electronic Medical Record, often used interchangeably with EHR. Although these two terms share many similarities, certain distinctions remain.
EMR specifically refers to the electronic version of paper forms used by healthcare institutions such as hospitals and clinics to record various patient data. EMRs include notes and related information collected and organized by physicians within a specific hospital or clinic, primarily to aid in diagnosis and treatment. In other words, an EMR typically contains only the data and information generated when a patient receives diagnosis and treatment at a single healthcare facility.
Generally, EMR can also be considered one of the data sources for EHR; therefore, data in EMR are usually part of the data in EHR.
PHR, short for Personal Health Record, is also a term with a very high usage rate. In fact, PHR is not a recently coined term; references to PHR date back to the 1970s, while the earliest scientific articles on PHR were published around 2000.
The term PHR is frequently used for both paper-based and electronic records, but it currently refers primarily to the storage of electronic data and information.
By definition, a Personal Health Record (PHR) typically refers to health-related medical data that is obtained and recorded by patients themselves. The key distinction from an Electronic Health Record (EHR) lies in the fact that an Electronic Medical Record (EMR) is maintained by healthcare institutions and contains medical information documented by physicians or data used for reimbursement support. In other words, a PHR can be described as an EHR that is established, accessed, and controlled by patients within a secure and private environment.
The information recorded in the PHR includes, but is not limited to:
Drug Allergies and Adverse Reactions
Chronic Disease
Family Medical History
Laboratory Test Results
Disease and Hospitalization Status
Radiographic images (e.g., X-rays)
Prescription Record
Surgical History and Other Treatment Courses
Vaccination Status
Observations of Daily Living
EHR/EMR/PHR in Internet Healthcare
This series of medical health records not only includes patients' medical histories but also incorporates data obtained from other hospitals and medical institutions, providing a rich data foundation that enables physicians to comprehensively interpret and analyze patients' health status. Abroad, numerous companies specialize in developing EHR/EMR software systems.
Unlike the limitations of paper records, EHR/EMR/PHR offer a range of benefits for optimizing patient diagnosis and treatment, such as:
Enable healthcare professionals to access data in EHR/EMR/PHR in real time
Facilitates healthcare professionals in identifying patients requiring screening and follow-up visits.
Monitor the treatment process by measuring specified parameters
Improving Treatment Outcomes Through the Use of Clinical Tools
Promoting Collaboration Among Different Healthcare Professionals
Optimizing Referral Transitions Between Different Healthcare Institutions
Better Access to Test Results for Effective Preventive Measures
Enhancing the Ability to Identify Missing Patient Information
Provide evidence-based recommendations for preventive healthcare
Warning of Potential Adverse Effects from Polypharmacy
Verify appropriate medications and dosages
Processes such as reducing redundant or unnecessary examinations
Current EHR/EMR Market and Future Trends
A report released by Accenture shows that the global EHR/EMR market will reach $22.3 billion by the end of 2015, with the North American market accounting for 47%, reaching $10.1 billion.
According to a report by BCC Research, the market size for EHR—including wireless-compatible patient monitoring devices, mobile EHR software, and EHR mobile technologies—is projected to reach $23.5 billion by 2018, with an expected compound annual growth rate (CAGR) of 16.1%.
The key drivers for the adoption of EHR/EMR are:
Government Planning and Fiscal Support
The Pressure to Reduce Healthcare Costs
The Need for Integrated Healthcare Systems Is Becoming Increasingly Urgent
The Extremely High Return on Investment of EHR Systems
Population Health Management Program
Increasing Demand for Healthcare Information Technology to Reduce the Risk of Medical Errors
Rising Incidence of Chronic Diseases
Barriers to Adopting EHR/EMR:
High Initial Investment
High Maintenance Costs
Defects and Deficiencies in Software Systems
Lack of Interoperability in Medical Data
It is difficult to operate in countries where the government does not provide subsidies for incentives.
Lack of Financial Incentives for Office-Based Physicians
Medical Standards for EHR/EMR Remain Lacking
Incompatibility with the auxiliary program still exists
Competition for Resources Among Healthcare Institutions
Barriers to Healthcare Professionals' Adoption of New Technologies
Currently, EHR/EMR/PHR systems are highly mature in healthcare institutions across many developed countries. With the continuous development of this field, we will increasingly recognize the importance of enabling the flow and interoperability of critical health information across different institutions and platforms, ensuring that patients receive optimal care regardless of their location.
