What does a deduplicated composite DXR record contain?

• A. Only unique patient identifiers
• B. The same information as a composite record, merged for duplicates
• C. A summary of patient care only
• D. Only the most recent data entries

Answer: (B)

A deduplicated composite DXR (Data Exchange Record) contains the same information as a composite record but merges multiple records for duplicates. This means that when patient data is collected from various sources, it often leads to multiple entries for the same individual. A deduplicated composite DXR takes these separate entries and integrates them into a single, coherent record, ensuring that the patient’s information is comprehensive and avoids redundancy.

This is critical for maintaining accurate patient care, as practitioners need access to complete and consolidated information about a patient’s history and treatments. The merging process ensures that all relevant data is preserved while eliminating confusion caused by duplicate entries.
