EHR vs EMR: What are the key differences? 

Discover the differences and similarities between electronic health records (EHR) & electronic medical records (EMR) to make informed healthcare decisions. 

Do you think you can clearly define the difference between an electronic health records (EHR system, and an electronic medical records one? I’ve sometimes heard from clients that they think they’re two different terms for the same thing, but there are real differences. Getting a handle on the nuances between the two is more important than you might think. For example, consider the following differences:  

• Scope of Information: EMR systems typically contain patient health information gathered in one healthcare organization, such as a hospital or clinic. EHR systems are designed to collect and store patient health information from multiple sources, including various healthcare organizations.  
• Interoperability: EHR systems are built with interoperability in mind, allowing for the exchange of patient data across different healthcare providers, systems, and geographical locations. This interoperability is essential for providing seamless care to patients, facilitating communication among healthcare professionals, and ensuring continuity of care. That’s not to say EMRs aren’t capable of interoperating with other systems—in fact, according to an article from Webpt, “a specialty EMR with interoperable functionality may actually be better than a large-scale, generalist EHR for many providers—especially those in niche fields. With these types of systems, providers are able to maximize their workflows and processes with solutions that are well-suited to their specific needs—and still thrive in this new era of connected, collaborative care.” 
• Regulatory Compliance: EHR systems are subject to more stringent regulatory requirements, such as those outlined in the Health Information Technology for Economic and Clinical Health (HITECH) Act and the Centers for Medicare & Medicaid Services (CMS) Promoting Interoperability Programs. These regulations aim to promote the adoption and meaningful use of EHR technology to improve healthcare quality, safety, and efficiency. Understanding these regulatory distinctions helps healthcare organizations ensure compliance and qualify for incentives or avoid penalties. 
• Data Analytics and Population Health Management: EHR systems typically offer advanced analytics capabilities for population health management, clinical decision support, and quality reporting. These features help identify trends, monitor health outcomes, manage chronic diseases, and improve population health initiatives. Understanding this disparity helps healthcare providers leverage data-driven insights to enhance patient care, streamline operations, and achieve better health outcomes at both individual and population levels. 

EHR and EMR adoption is becoming commonplace for healthcare providers, as seen in this chart from HealthIT.gov, which shows that a majority of providers have adopted some form of an electronic patient tracking system:  

Understanding the differences between EHR and EMR systems is essential to make informed decisions about selecting, implementing, and leveraging electronic health records technology to improve patient care, operational efficiency, regulatory compliance, and population health management efforts. 

Let’s delve deeper into a detailed comparison of EHR and EMR systems, focusing on their functionalities, interoperability, and data accessibility: 

Functionalities 

EMRs are digital versions of paper charts within a single healthcare organization. They contain patient medical and treatment histories, diagnoses, medications, immunization dates, allergies, and laboratory test results. EMRs are primarily used for diagnosis and treatment within the organization where they are implemented, but they also streamline workflows within the organization, such as appointment scheduling, prescription management, and clinical documentation. Additionally, EMRs often include tools for medical billing and coding. 

EHRs are broader in scope and encompass health information from multiple healthcare organizations. They contain comprehensive patient health information, including medical history, diagnoses, medications, allergies, laboratory results, imaging reports, vital signs, progress notes, and treatments. EHRs support interoperability, allowing information exchange across different healthcare providers and settings. This also helps to facilitate care coordination among healthcare professionals by providing a centralized platform for accessing and sharing patient data. EHRs often include features for patient engagement, such as patient portals for appointment scheduling, secure messaging, and access to personal health records. 

Interoperability 

EMR systems are typically designed for internal use within a single healthcare organization. That means their Interoperability capabilities can be limited, making it challenging to exchange patient data with external systems or providers. Data exchange may rely on standard formats like HL7 (Health Level Seven) but may require customization and integration efforts. But that’s not to say EMR systems aren’t interoperable—in fact, many innovative solutions are just as functional for interoperability as large EHRs.  

The distinction is EHR systems are built with interoperability in mind, aimed at enabling seamless data exchange among different healthcare organizations, systems, and stakeholders. They support interoperability standards, such as HL7, FHIR (Fast Healthcare Interoperability Resources), and CCD (Continuity of Care Document). EHRs facilitate health information exchange (HIE) initiatives, allowing for the secure sharing of patient data across organizational boundaries. 

Data accessibility 

Access to EMR data is typically limited to authorized users within the healthcare organization where the system is deployed. Data accessibility may vary based on user roles and permissions set by the organization’s administrators. Patients may have limited access to their medical records, often requiring requests through the healthcare provider or institution. 

EHR systems prioritize patient data accessibility and empower individuals to access their health information securely. Patients can access their EHRs through online portals, mobile apps, or personal health record (PHR) platforms. EHRs support data exchange with external stakeholders, such as other healthcare providers, specialists, pharmacies, and public health agencies. Data accessibility in EHRs promotes patient engagement, self-management, and shared decision-making, leading to improved health outcomes and satisfaction.
