When migrating from an old electronic health record to a new system, which factor is most important to assess?

• A. Bandwidth
• B. Sustainability
• C. Ease of transferring data from previous system
• D. Maintenance

Answer: (C)

Transferring data from the old system is the most important factor to assess because the success of an EHR migration hinges on preserving the patient’s historical information in a usable form. If you can move complete and accurate medication lists, allergies, problem lists, lab results, imaging, notes, attachments, and the associated metadata (timestamps, authorship, and audit trails), clinicians can continue care without gaps, avoid medication errors, and maintain regulatory compliance. This requires careful data compatibility, mapping to the new system’s structures, and quality checks to prevent loss, duplication, or misinterpretation of records.

Bandwidth, sustainability, and maintenance matter for ongoing use, performance, and long-term support, but they do not resolve the immediate risk of losing or corrupting essential data during the transition. That's why ensuring a reliable data transfer process is the top priority.
