What are electronic health records?

Electronic Health Records (EHRs) are digital versions of a patient's medical history that healthcare providers maintain over time. They include key health information, such as medical history, diagnoses, medications, treatment plans, immunization dates, allergies, lab and test results, and radiology images.

EHRs can be created, managed, and consulted by authorized healthcare providers and staff across different healthcare organizations. They are designed to go beyond standard clinical data to provide a broader view of a patient’s care and make health information available to patients and their doctors instantly, thereby enhancing the overall quality of care.

What are the common features of electronic health records?

Electronic health records come with a variety of features that streamline healthcare delivery and improve patient care. Common features include:

Patient demographics 

EHRs include basic information such as age, gender, contact details, and insurance information. This data is essential for identifying patients and ensuring accurate billing. Having up-to-date demographic information also helps in analyzing patient populations and improving care delivery.

Medical history 

EHRs provide a comprehensive record of past illnesses, surgeries, family medical history, and lifestyle factors. This information helps healthcare providers understand the patient's overall health. It also aids in making informed decisions about treatment and preventive care.

Medication management 

EHRs track current and past prescriptions, dosage information, and refills. This feature helps prevent medication errors and adverse drug interactions. It also allows providers to monitor patient compliance and manage long-term treatments more effectively.

Order entry 

Electronic ordering of tests, medications, and procedures is a key feature of EHRs. This reduces errors related to handwriting and miscommunication. It also speeds up the processing of orders, improving efficiency and patient care.

Clinical notes 

EHRs store detailed notes from healthcare providers documenting patient encounters and care plans. These notes provide a clear record of the patient's progress and treatment. They are essential for continuity of care and for communicating with other providers.

Lab and imaging results 

Integration of laboratory test results and radiology images allows quick access and review. This feature helps providers make timely and accurate diagnoses. It also facilitates the sharing of results with other healthcare professionals involved in the patient's care.

Decision support 

EHRs include alerts and reminders for preventive measures, drug interactions, and critical lab values. These tools support providers in making evidence-based decisions. They also help in maintaining high standards of patient safety and care.

What's the difference between electronic health records and electronic medical records?

Definition and scope 

Electronic health records are comprehensive digital records of a patient's entire health history, accessible across different healthcare settings. EHRs include data from various providers and can be shared with authorized users to coordinate care. In contrast, electronic medical records (EMRs) are digital versions of paper charts in a single provider’s office and are typically not shared outside of that practice.


EHRs are designed for interoperability, meaning they can exchange information seamlessly with other EHR systems. This allows for better coordination of care among different healthcare providers and facilities. EMRs, however, are generally limited to internal use within one healthcare practice and do not easily share data with other systems.

Comprehensive care vs. specific treatment 

EHRs support comprehensive care by providing a holistic view of a patient's health, including all treatments and interactions across multiple providers. This broad scope helps in managing chronic conditions and preventive care. EMRs focus on the medical treatment provided by a single healthcare provider, covering the clinical data specific to that provider's interactions with the patient.

Patient access 

Patients typically have access to their EHRs through patient portals, allowing them to view their health information, lab results, and medication lists. This access encourages patient engagement and self-management. EMRs usually do not provide direct access for patients, as they are intended for use within a specific provider's practice.

What are electronic health record standards?

Electronic health record standards ensure the compatibility and interoperability of EHR systems across different healthcare settings. These standards enable consistent and secure sharing of patient information among providers, enhancing the quality and continuity of care.

Health Level Seven (HL7)

HL7 is a set of international standards for the exchange, integration, sharing, and retrieval of electronic health information. These standards facilitate communication between various healthcare systems. HL7 covers a wide range of data types and ensures that different systems can work together seamlessly.

Fast Healthcare Interoperability Resources (FHIR)

FHIR is a standard describing data formats and elements for exchanging electronic health records. It is designed to enable easy and fast data exchange, even on mobile devices. FHIR allows developers to create applications that can access and use health data, promoting innovation in healthcare IT.

Clinical Document Architecture (CDA)

CDA is an HL7 standard that defines the structure of clinical documents. It ensures that documents like discharge summaries and progress notes are formatted consistently. This consistency makes it easier to share and understand clinical information across different systems and providers.

DICOM (Digital Imaging and Communications in Medicine)

DICOM is the standard for handling, storing, and transmitting medical imaging information. It ensures that images and related data can be exchanged and viewed on different medical imaging devices and systems. This standard is crucial for the integration of radiology and imaging into EHRs.

ICD-10 (International Classification of Diseases)

ICD-10 is a coding system used to classify and code all diagnoses, symptoms, and procedures recorded in conjunction with hospital care. It provides a standardized way to represent health conditions, which is essential for billing, reporting, and research. Using ICD-10 codes in EHRs helps ensure accuracy and consistency in medical records.
