EpicCare Practice Exam

Data quality deduplication in Epic is about identifying and removing duplicate patient records so there’s one accurate, unified entry for each person. Duplicates can pop up when a patient is entered with slight name variations, different birth dates, or when data comes from multiple systems, leading to fragmented histories and potential errors in care or reporting. By deduplicating, Epic creates a single master patient index, merging related encounters, orders, results, and notes into one record, which improves safety, data integrity, and reliable reporting.

So the purpose is to remove duplicate patient records. The other options don’t fit because creating duplicates would worsen data quality, anonymizing data is about privacy, and changing IDs randomly would corrupt the linkage between records and activities.
