EHR Data Migration: Process, Challenges, Benefits, and Best Practices

Data migration in Electronic Health Records (EHR) involves the transfer of digital health records, patient data, and medical documentation between different EHR systems. It is now common for healthcare organizations to switch to new, more advanced systems and new digital solutions. With this, the secure and precise transfer of data becomes critical for seamless provision of healthcare services.

EHR migration is not simply the transfer of data from one storage system to another. It involves extensive preparation and system controls to the transfer of data and the protection of data integrity and accessibility.

What Does EHR Data Migration Involve?

The migration of EHR data involves the transfer of digital records from one health system to another electronically. This transfer may be between different databases, systems, and even across different providers.

There are many different types of data that are migrated, from:

• Personal patient data
• Medical history records
• Diagnoses and treatment
• Medications
• Allergies and lab results
• Imaging and medical notes
• Reports and plans
• Clinic, insurance and billing records
• Appointment history

Providing the healthcare system added functionality and the ability to access more health data, while also protecting and preserving health data, is an important reason for EHR migration.

What are the Reasons for EHR Migration in Healthcare?

There are many reasons for EHR migration in healthcare.

The New EHR System

To get new features, improved user interfaces, enhanced data security, and advanced analytic capabilities, organizations may need to switch to a new EHR system.

Mergers

If a new healthcare system is created from a merger, the patient records and data systems from the separate organizations need to be merged.

Shifting to Cloud Solutions

Healthcare organizations prefer cloud-based scalable, easily manageable, and more accessible EHR systems over traditional location-based systems.

Better Data Management

Outdated systems might have outdated frameworks, duplicated data, and poor reporting, if any. Migration helps in data cleansing and structuring.

Growth of Patient Care

Improving the ease and accuracy of data enhances decision making and reduces the errors of care providers and helps to give better and more individualized care.

EHR Data Migration Types

The needs of the organization determine the type of migration strategies.

Total Data Migration

This is a total transfer of all patient data and information to a new EHR. Organizations that want to keep a complete and unbroken historical record, use this strategy.

Select Data Migration

This is the transfer of only a certain class of data, for example, transferred treatment data, visits, or medications. This strategy saves time and space on the new system.

Migration by Archiving

This is the transfer of all active patient data to the new EHR and the transfer of all other patient data to a secure archiving system.

This strategy is useful for organizations that have a large volume of historical data.

Migration by Combination

This is a merger of archived data and active data based on the needs of the organization.

Migration of EHR Data

The migration of the EHR data involves a lot of planning and migration is done in multiple phases.

The EHR Data Migration Process

Step 1. Planning and Evaluation

This is the phase where the system to be migrated is reviewed, the data to be migrated is assessed, and the goals of the migration are defined.

During this phase, organizations analyze the following:

• Current data volume
• Data quality
• System compatibility
• Compliance requirements
• Migration timelines
• Required resources.

More detail provided in the migration plan helps reduce risks for the future and potential problems.

Data Extraction

During this step, data is securely extracted from the current EHR system. Data can be pulled from:

• Databases
• Electronic Files
• APIs
• Data Exports
• Clinical Data HIEs.

Extreme caution is required during this step so data does not become incomplete or altered.

Data Cleaning and Preparation

Organizations wish to ensure the quality of data post movement and thus review and enhance data quality from the current state to the end state.

This can involve the data quality activities of:

• Removal of duplicates
• Correction of data
• Format standardization
• Identifying and resolving missing data.

With the data quality activities above and the complete data within the new EHR system, the data quality is improved.

Data Mapping and Transformation

Different EHR systems store and catalog data in different ways. Data mapping ensures that data from the old system is placed in the proper structure of the new EHR system.

For this alignment, the following is required in the new system:

• Mapping for patient data
• Medical codes
• Dates
• Meaning of clinical data.

Data mapping is essential to ensure that data is not transferred in a loss state or an incomplete and flawed state.

Data Loading

EHR systems have the capacity to accept data once it is cleaned and formatted.

Prior to the actual migration, the data loading step is performed for a Test Migration in the new EHR system and all migration activities are undertaken to identify risks and problems.

Testing and Validation

The quality of the data migration process is assessed by verifying the accuracy and completeness of the data moved.

The validation activities to ensure the data quality of the data migrated, especially the medical data, include verifying the data for:

• Patients
• Medical History
• Medication
• Labs
• Clinical Notes
• User Permissions

Healthcare personnel must ensure that the data of highest priority to them has been captured in the new system in preparation for the System Go-Live.

Final Migration and Deployment

The Final Migration is performed after the completion of all the tests.

The final migration is usually scheduled during the least busy times to limit the effects on operating healthcare functions.

Common Challenges in EHR Data Migration

There are challenges that are met during EHR migration, despite the benefits of EHR migration.

Data Compatibility Issues

Data conversion is often difficult due to the use of different formats, structures, and coding standards in different EHR systems.

Data Loss Risks

Missing information and data corruption may be due to lack of planning, and/or mistakes during the process.

Maintaining Data Accuracy

Clinical information is important and leaving it out of the mapping process may cause it to be inaccurately placed in the new system.

Security and Privacy Concerns

Data migration should have security measures to protect data from being accessed without authorization due to the data being sensitive.

Downtime Management

Disruptions should be limited to ensure that patient care is not affected.

Regulatory Compliance

The patient information being processed must adhere to all of the applicable privacy and security regulations.

Benefits of EHR Data Migration

There are substantial benefits of migrating EHR systems.

Improved System Performance

The EHR systems of today are designed such that they are easier to use with improved workflows and faster access.

Better Patient Care

Healthcare providers are better able to make informed healthcare decisions when they have complete and accurate medical records.

Enhanced Data Security

Strong data protection and security are features of newer systems.

Better Reporting and Analytics

The migrated data is better suited to help report and analyze healthcare data rendering improved healthcare analytics.

Increased Operational Efficiency

Improved processes and reduction of administrative tasks are benefits of having a well-designed EHR system.

Best Practices for Successful EHR Migration

Healthcare organizations can achieve a seamless migration when a set of best practices are observed.

Create a Detailed Migration Strategy

Before starting migration, outline your goals, deadlines, and who is responsible for what, and outline your risk management strategies.

Perform Data Quality Checks

Look through existing records and check for data issues, such as data records that are not complete, data records that contain errors, and data records that exist in multiple copies.

Involve Healthcare Staff

In your migration planning and testing, include clinical and administrative staff, as they understand the clinical and administrative workflows.

Maintain Strong Security Measures

During the entire migration process, apply strong security, including the use of encryption for data, secure methods of data transfers, and secure and controlled methods of data access.

Conduct Multiple Test Runs

Run as many tests as possible to migrate to production, and correct the issues that are found.

Keep Backup Copies

Backup all data transfer to a secure location before migration.

Future of EHR Data Migration

The future of healthcare services and EHR systems will drive the migration of healthcare data into EHR systems at a greater pace and with more advanced methods and systems. AI, automation, the cloud, and standards of interoperability will assist in faster and accurate healthcare data transfers.

More automation in migration will help mitigate errors of a manual data migration processes and help healthcare systems migrate data faster.

Conclusion

In the migration of EHR data, the most important aspects are planning, securing data, accurate mapping, and testing.

While migration of healthcare data to EHR systems will encounter challenges like security, data accuracy, and integration issues, a healthcare system that has embraced best practices for migration will address these issues with ease as a future-proof migration strategy. Healthcare systems that fail to migrate will be ineffective, and lose to their competition on all fronts.
