EMR, or electronic medical record, is a digital version of a patient’s chart created and maintained by a single healthcare organization. It is intended to support clinical decision making and day-to-day care within that organization. EMRs are frequently contrasted with electronic health records (EHRs); while EMRs provide a comprehensive collection of a patient’s data within one site, EHRs are designed to be portable across providers and settings to reflect a broader continuum of care.

Contents typically include patient demographics, problem lists, allergies, medications, immunizations, vital signs, lab results, radiology images and reports, treatment plans, orders, and clinician notes. Common features include computerized order entry, e-prescribing, clinical decision support, medication reconciliation, and reporting. Interoperability efforts use standards such as HL7 and FHIR, and terminologies like LOINC and SNOMED CT, to enable data exchange among systems and with health information exchanges.

Advantages cited include improved legibility, reduced duplication, faster access to records, more complete documentation, and decision-support for screening reminders and safety checks. Challenges include high initial and ongoing costs, workflow disruption, data entry burden on clinicians, and concerns about data quality and interoperability across vendors. Privacy and security measures, such as access controls, audit logs, encryption, and compliance with laws like HIPAA in the United States, are essential.

Adoption varies by country and setting. Evidence on patient outcomes is mixed, with reported gains in efficiency and coordination but mixed effects on clinical outcomes depending on implementation quality and context. The field continues to evolve with emphasis on interoperability, cloud-based solutions, and user-centered design.
