What is an EHR system? A complete guide to electronic health records 

A patient's chart lives in a dozen places at once: the admitting hospital's system, the referring physician's notes, a lab's results portal, an insurer's claims file. Every handoff between those systems is a moment where protected health information can leak, get duplicated, or simply go missing, and compliance officers are the ones who answer for it.

According to IBM's Cost of a Data Breach Report (2025), healthcare breaches cost an average of $7.42 million each and take 279 days to identify and contain, longer than any other industry. An EHR system is supposed to fix that fragmentation. Used well, it becomes the biggest single compliance surface an organization has.

This guide breaks down what an EHR system actually is, the benefits and risks it brings, and the legal requirements that apply depending on where your organization operates.

Key takeaways

• An EHR system is a digital record of a patient's health information, built to be shared across the providers treating that patient
• Nearly every country has its own legal framework for electronic health records: HIPAA in the US, UK GDPR and the emerging Single Patient Record in Britain, the mandatory opt-out ePA in Germany, and the DMP inside Mon espace santé in France, among others
• Centralized records improve care coordination and cut duplicate testing, but they also concentrate risk: a single breach exposes far more data than a paper file ever could
• Compliance depends less on the EHR itself and more on how the documents feeding into and out of it are stored, retained, and audited
• Standards-based integration keeps an EHR system connected to the rest of your document environment long after any single vendor relationship ends

What is an EHR system?

An EHR system is software that stores and manages a patient's health information electronically, in a format designed to be shared across the providers treating that patient. It holds diagnoses, medications, lab results, imaging, and treatment history in one continuously updated record.

The term gets used loosely, so it helps to separate it from two related ones. An electronic medical record (EMR) is the digital chart kept by a single practice or hospital, built for internal use. An EHR is broader by design: it follows the patient across providers. Several countries also have their own statutory version of this concept with its own name and legal basis, such as Germany's ePA (elektronische Patientenakte) or Austria's ELGA, which function as a nationally regulated EHR.

Legal requirements for EHR systems by country

Electronic health records sit inside some of the strictest data protection frameworks that exist, and the specific rules vary sharply by country.

United States

There is no single federal mandate requiring every provider to run an EHR system, and the US healthcare system itself is a mix of public programs and private insurers, not one national scheme. What does apply universally is the Health Insurance Portability and Accountability Act (HIPAA), in force since 1996, which sets physical, network, and process-level security requirements for anyone handling protected health information (PHI). Any organization treating US patients and storing their data electronically falls under HIPAA's compliance rules, whether it runs a formal EHR system or a patchwork of tools.

United Kingdom

The NHS manages patient information as a single, taxpayer-funded system. Coverage today comes from regional Shared Care Records, which let providers in a given area exchange patient data, plus the Federated Data Platform, which supports operational functions like waiting-list and discharge management. In 2026, the UK government introduced the NHS Modernisation Bill to legislate a Single Patient Record: one authoritative digital record spanning a patient's whole NHS and social care history, with patient-facing access through the NHS App expected from 2028. Patient data itself is governed by UK GDPR and the Data Protection Act 2018, adopted after Brexit as the successor to EU GDPR.

Where your EHR documents fit into a wider compliance strategy

An EHR system manages the clinical picture, but it was never designed to be the long-term, audit-proof archive for everything that feeds into it. Referral letters, consent forms, insurance correspondence, discharge summaries, and diagnostic images all need to be captured, classified, and retained under rules that can outlast the EHR vendor contract itself.

That's a document management problem as much as a clinical one. Documents need to be findable years after the encounter that created them, retained for the legally mandated period for that record type and jurisdiction, and protected by an access model that reflects who actually needs to see them. When these functions live inside the EHR itself, they tend to be an afterthought. Run them on a dedicated content platform instead, and the EHR stays focused on active treatment while the underlying documents stay compliant regardless of what happens to the clinical system around them.

This is also where interoperability standards do the real work. An EHR system that can only talk to itself recreates the exact fragmentation it was meant to solve, just one layer down.

Managing EHR-related documents and compliance with Doxis

Doxis works alongside your EHR system rather than replacing it, and it isn't a certified EHR itself. What it does is give healthcare organizations a compliant, centrally managed archive for everything that surrounds the EHR, connected through the same interoperability standards hospital IT teams already use: HL7 v2 for admission, transfer, and discharge messaging, and a FHIR R5 service for exchanging Patient, Encounter, and Document resources. This integration is standards-based, so it works with the EHR platform you already run without a vendor-specific plug-in to maintain.

That capability sits inside Doxis for healthcare, part of the broader Doxis Intelligent Content Automation platform that financial services and manufacturing customers also use for contract management and invoice processing. For healthcare specifically, documents captured from the EHR, DICOM imaging archives, and referral or insurance paperwork land in one governed repository, with role-based access (clinicians scoped to their facility or ward, DRG coders scoped across facilities), a documented VIP protection concept for sensitive patient records, and an audit trail on every access.

• Centralizes documents from your EHR, PACS, and administrative systems in one compliant archive
• Applies role-based access control, including dedicated protections for VIP patients
• Supports HIPAA-compliant document handling alongside ISO 27001, GDPR, and SOC 1/2/3 certifications
• Connects via HL7 and FHIR R5, so clinicians can reach archived documents without leaving their primary system
• Automates retention scheduling so records are kept exactly as long as regulations require
• Extends the same governance model across every department in your organization

Doxis is recognized as a Leader in the Gartner® Magic Quadrant™ for Document Management, and an independent Forrester Total Economic Impact™ study found a 336% ROI over three years for organizations running Doxis.
