EMR Cloud Migration: Benefits, Process, Challenges, and Best Practices

Electronic medical record systems keep track of patient histories, diagnoses, prescriptions, test results, and billing. Traditionally, healthcare organisations have kept electronic medical records on local servers. Many concerns, including cybersecurity, have prompted further interest in EMR cloud migration.

EMR cloud migration is the transfer of cloud-based electronic medical record applications, databases, and associated services from local infrastructures to the cloud. This process involves much more than the technical transfer of data. Some of the main areas that need to be considered and monitored after the migration process include data protection during the migration process, thorough testing and analysis of the workflows and staff training on the system, and the migration should be done in phases.

What Is EMR Cloud Migration?

EMR cloud Migration refers to the transfer of hosted electronic medical records from local servers to cloud infrastructures.The migration process may include the transfer of a number of electronic medical records, including but not limited to:

patient demographics, histories and progress notes, lab reports and images, medications and allergies, appointments and logs, insurances and billing records, users and their permissions, clinical templates and forms, and clinical workflows and integrations with other external systems in health care, as well as all other archived records and documents.

Electronic medical record systems can be locally or cloud hosted. Cloud hosted systems are those that are hosted over the internet.

Why Are Healthcare Organisations Moving EMRs to the Cloud?

Healthcare organisations need systems that provide secure access, support growing data and seamless interoperability, and ensure active business continuity. Self-hosted systems can require a large capital investment into servers and storage, as well as security and maintenance staff, and ongoing software and security updates.

Cloud migration offers a solution to old hardware by flexibly enabling clinical operations.

Easily Scalable

Healthcare data storage needs grow with each new patient and each new report, image, prescription, and clinical note. Cloud infrastructure is easily expandable, allowing storage and processing needs to grow without the need to purchase new physical servers.

Remote and Secure

Cloud-based EMR systems allow secure access of authorized personnel from selected locations and devices. It supports clinical personnel that work in multiple locations, remote personnel, and authorized access during a critical situation.

Remote access is only useful when supported by strong character authentication, access controls, data encryption, and a constant evaluation of systems.

Improved Business Continuity

Local systems can be damaged by degraded or failing hardware, fire, flooding, power loss, cyber systems attack, and damage by personnel and still become unavailable. A properly built cloud environment provides less risk for system backup and business continuity.

Even though the risk is mitigated, the organization is still responsible for ensuring that backup systems function, and data is available and uncorrupted.

Key Steps to EMR Cloud Migration

A planned and structured migration process improves the likelihood of uninterrupted and secured records with minimal downtime and disruption of your normal workflow.

Assess the Existing Environment

Establishing a baseline inventory for the systems, data, and accounts, as well as the infrastructure and user access and service storage, is the first step.

These details help assess:

• The nature and quantity of data
• What records are incomplete or duplicated
• Security vulnerabilities
• What laboratory and billing systems are in use
• Requirements for Internet and other networks
• What records are required by retention schedules
• What current backup processes are in place
• What important clinical workflows are in place

This assessment helps the initial planning for migration.

Define Migration Goals

Healthcare entities have a variety of migration goals. Improved remote access, reduced hardware expenditures, improved resiliency and speed of the system, and the ability to accommodate the growth of the organization are a few of the migration goals. Migration goals also help assess the migration’s success.

Develop a Data Migration Plan

Not all files should be moved. This may include files that are old, duplicated, corrupted, or not useful, as these may strain the storage and the manageability of the new system.Data should be scrubs, reorganized, and categorized and data should be placed in a structure prior to the migration. During all of these activities, the quality of clinical data must be preserved.

Plan Security and Compliance

Given that medical records contain sensitive data that must remain private, the protection of data must be incorporated in each of the phases of migration. Cloud security planning must consider these aspects:

• Encryption during transfer and storage
• Multi-factor authentication
• Role-based access control
• Audit logs
• Secure backup systems
• Continuous threat monitoring
• Incident response procedures
• Data retention and deletion rules
• Employee security training
• Regular vulnerability assessments

Cloud services must still address the threats and vulnerabilities to the security of electronic health information in health care organizations.

Test Before Full Migration

All records should not be migrated before one small pilot migration is done. This migration helps flag errors for inconsistent formats, slow integration, missing fields, access issues, and workflow interference.

Testing should confirm the following:

• Completeness of patient records
• Correct dates and codes
• Validating that attachments open
• User permissions
• Accuracy of reports
• Integrated systems
• Restoration of backups
• Integrated systems
• Migration meets the operational performance

All errors should be rectified before proceeding to the full migration.

Train Employees

A technically correct migration can still “fail” if employees are not versed in the new system. Different employees from the clinics, nursing, and administration may require different training.

Training should include access to system logs, privacy and security procedures, and how to report issues during system downtime.

Training employees using a “live” system with clear guides will reduce “surprises” after the system launch.

Complete the Migration

The full migration should be done when it will have the least impact. A phased approach is to migrate one department at a time or one data set at a time. An alternative is to set the migration date and time, after which all systems are switched over.

There should be procedures for managing temporary service disruptions to ensure that staff can still access critical patient information.

Validation and Monitoring of the New System

Post-migration, the original and the new data should be validated against one another by the relevant teams. This includes a verification check for data record counts, field values, attached files, permissions, and associated integrations.

Even after the new system has been fully implemented, monitoring should continue to look for abnormal access, performance delays, backups that have not executed, security incidents, and even support challenges of system users.

Challenges of Common EMR Cloud Migration

Data incompatibility remains the most significant issue in EMR systems. Legacy and new EMR systems store data differently, and harmonized data and interoperable systems can facilitate the use and exchange of electronic health information.

• Missing or duplicate patient records
• Data mapping errors
• Unpredicted service disruptions
• Poor internet service
• Failed integrations
• Change-resistant employees
• Poor security controls
• Data ownership ambiguities
• Limited backup testings
• Migration costs that exceed forecasts

These risks can be better predicted and planned for with early, phased, clear testing accountability, and rollback plans.

Cloud Migration Best Practices

The patient care and system performance aspects of an EMR cloud migration should not be impacted by the migration. Staging the migration to improve system performance should not be the goal.

Best practices of an EMR migration include: an unaltered system backup, validations of all critical workflows, role-based access for the new system, migration documentation, and system testing by clinical staff.

This migration should not be perceived by employees as a black box initiative due to staff the migration step risks not being supported. Employees should be informed about the migration’s purpose, the expected changes to their workflows, the schedule for required migration training, and how to access support.

Final Thoughts

Healthcare organizations have the opportunity to craft an advanced digital landscape thanks to the scalable, adaptable, and resilient systems afforded by EMR cloud migration. Enhancing the digital architecture with the agility and speed of cloud computing does not simply mean hosting files on another server.

A successful migration occurs after careful planning of each phase: assessment, cleaning, and planning. This continues with security, sampling, training, and monitoring. The integrity, availability, and confidentiality of patient data is preserved, and the organization minimizes disruption.

FAQS

How long does EMR cloud migration take?

The scope of the migration, the quality of the data, the complexity of the systems, the number of required integrations, and the size of the organization inform the duration of the migration. Small migrations can take a couple of weeks; complex migrations that span multiple departments can take several months.

Is it safe to store medical records in the cloud?

Cloud storage can be a safe way to manage medical records, but ELAs must be in place. Safeguards include the application of layered and continuous security, monitoring, auditing, and assessing risks, as well as maintaining secure data backups. Additionally, the hosting organization must comply with the laws and regulations of the jurisdictions in which it operates.

Can an EMR system be used during migration?

In some circumstances, limited access can be sustained during migration in phases, or by other means such as read-only access, temporary systems, or a carefully prioritized schedule of cutover periods. However, system owners should be prepared for migration Downtime.
