Electronic medical records contain some of the most sensitive personal information that exists. Diagnoses, medications, surgical histories, mental health records, and insurance details all live inside an EHR. It is a reasonable and important question for both healthcare professionals and patients to ask: where exactly is this information stored, and how is it kept secure?
The answer depends on the type of EHR system your organization uses. Understanding the different storage models helps healthcare administrators make informed decisions about infrastructure, security, and what happens when those systems go offline.
The Three Primary Storage Models for Electronic Medical Records
1. On-Premises (Local Server) Storage
In an on-premises EHR model, patient data is stored on servers physically located within the healthcare facility or on a server managed by the organization’s own IT department. The organization owns and maintains the hardware, manages software updates, and is directly responsible for backup and security protocols.
This model gives healthcare organizations maximum control over their data. It is common in larger health systems that have dedicated IT infrastructure and the resources to manage it. The tradeoff is cost. Hardware must be purchased, maintained, and eventually replaced. IT staff must manage updates and security patches. And if those servers are affected by a fire, flood, power failure, or cyberattack, data can be at risk if offsite backups are not current.
2. Cloud-Based Storage
Cloud-based EHR storage is the fastest-growing model in healthcare today. In this approach, patient data is stored on remote servers managed by a third-party EHR vendor or cloud provider such as Amazon Web Services, Microsoft Azure, or Google Cloud. Healthcare staff access the system through a web browser or application over a secure internet connection.
The cloud model shifts the burden of infrastructure management to the vendor. Healthcare organizations do not need to purchase or maintain servers, and scaling capacity is straightforward. Cloud-based systems are also designed with HIPAA compliance requirements built in, including data encryption both in transit and at rest, access controls, and audit logging.
One important consideration with cloud-based storage is internet dependency. If your facility loses internet connectivity, access to patient records can be interrupted. This is precisely why EHR downtime solutions are critical regardless of your storage model. When the cloud is unreachable, a local downtime system ensures that patient care continues without disruption.
3. Hybrid Storage
Many healthcare organizations use a hybrid approach, maintaining some data locally while also leveraging cloud infrastructure for backup, redundancy, or specific applications. A hybrid model can offer the control of on-premises storage with the resilience and scalability of cloud backup.
What Data Is Actually Stored in an EHR?
Electronic medical records typically contain a patient’s full clinical history, including:
- Demographic and insurance information
- Medical diagnoses and problem lists
- Medication lists and prescription records
- Allergy information
- Laboratory results and radiology reports
- Clinical notes from physicians and nurses
- Surgical and procedure histories
- Immunization records
- Consent forms and patient signatures
All of this data is structured and indexed to allow authorized users to retrieve it quickly. In modern EHR systems, this data is also increasingly used to generate automated alerts, support clinical decision-making, and enable population health analysis.
How Is EHR Data Kept Secure?
HIPAA, the Health Insurance Portability and Accountability Act, sets the federal standard for protecting electronic protected health information (ePHI) in the United States. EHR systems, regardless of where data is stored, must comply with HIPAA security requirements, which include:
- Encryption of data at rest and in transit
- Role-based access controls that limit who can view or modify records
- Audit logs that track who accessed what data and when
- Breach notification protocols
- Regular security risk assessments
Cloud-based EHR vendors typically invest heavily in security infrastructure because protecting healthcare data is their core business responsibility. However, healthcare organizations remain responsible for ensuring their contracts with vendors include appropriate Business Associate Agreements (BAAs) under HIPAA.
The Special Challenge of Downtime and Data Accessibility
One of the most overlooked questions in EHR storage is what happens to data accessibility when the primary system is unavailable. Whether data is stored on-premises or in the cloud, outages occur. Network failures, ransomware attacks, and scheduled maintenance can all interrupt access to patient records at the most critical moments.
This is where a dedicated downtime solution becomes part of your data storage and continuity strategy. dbtech’s EHR Downtime Solution maintains a current copy of critical patient data on isolated local workstations, ensuring that clinical staff can access census reports, medication administration records, and patient documentation even when the primary EHR is completely offline.
The data stored in dbtech’s downtime system is encrypted, and access is restricted to credentialed users only. After a downtime event ends, information captured during the outage is exported back to the EHR in HL7 format, maintaining a complete and accurate record.
Document Management and Long-Term Record Storage
Beyond the EHR itself, healthcare organizations manage large volumes of scanned documents, paper forms, and clinical attachments that must be stored securely and retrieved efficiently. dbtech’s Ras document management solution provides electronic patient folders that store scanned images, electronically captured documents, and uploaded files in a secure, organized environment.
This document storage integrates with your EHR, giving staff a single point of access for the full scope of patient information rather than having critical documents scattered across multiple systems.
Integrate dbtech with your EHR
Electronic medical records are stored in local servers, cloud environments, or a combination of both, depending on the healthcare organization’s size, resources, and technology choices. Regardless of which storage model you use, the security and continuous accessibility of that data are non-negotiable obligations to your patients and your clinical staff.
A complete EHR strategy includes not just where records are stored, but what happens when those systems go down. Explore dbtech’s solutions to learn how to ensure your patient data remains accessible, secure, and recoverable under any circumstance.
