EHR vs EMR: Main differences
Despite the Similarities Between EMR and EHR, some key distinctions set them apart. These include:
Scope of information
The main difference between EMRs and EHRs lies in the scope of the information they store. An electronic medical record (EMR) refers to the patient data collected within a specific healthcare setting, typically during a single patient visit or treatment episode. An electronic health record (EHR) contains a more comprehensive view of a patient's health, pulling together patient information from various sources, including different healthcare providers and facilities.
EHRs give healthcare professionals access to a digital version of a patient's total health information, allowing for a more complete patient's medical history to inform treatment decisions.
Interoperability
While both EHR and EMR systems store electronic records, the level of interoperability differs significantly. Electronic health records are designed to share and exchange data across multiple healthcare systems and with other health care providers. This allows clinicians involved in the patient's care, whether at imaging centers, emergency rooms, or clinician's offices, to access and update the same patient's record in real time.
In contrast, EMRs are more isolated, containing patient records within a single practice, without the ability to seamlessly share information with other systems.
Patient engagement
One of the significant advantages of EHR systems is their inclusion of patient portals, which enable patients to engage actively in their care. Through these portals, patients can access their patient's medical information, view lab results, and communicate with authorized providers. This level of engagement allows for greater patient insights into their treatment plans and fosters more proactive management of their patient's health.
EMR systems do not typically include these features, as they are primarily used for internal documentation of a patient's care within a single facility.
Legal requirements
Both EMR and EHR systems must comply with privacy regulations, but the requirements differ. EMR systems are governed by the Health Insurance Portability and Accountability Act (HIPAA), ensuring that patient's medical information remains secure. However, EHRs have additional legal obligations due to their broader scope and ability to share data. These requirements include ensuring interoperability and supporting patient access to their records.
Cost
The financial implications of implementing and maintaining these systems also differ. EMR systems are generally more cost-effective for healthcare organizations due to their narrower functionality. On the other hand, EHR systems require a larger investment because of their expanded capabilities, including interoperability, electronic prescribing, and patient portals.
However, the long-term advantages of EHRs, such as improved population health management, reduced duplicate tests, and enhanced coordination of care among all the healthcare providers involved in a patient's care, often lead to greater cost savings over time.
