Which column is used to identify completed office visits?

The correct choice indicating how to identify completed office visits is based on the use of the column "EncounterFact.DerivedEncounterStatus." This column specifically holds values that represent the status of an encounter in a more formatted or derived manner, reflecting the final status after considering various factors that might affect the visit, such as cancellations or no-shows.

In many data models, including Caboodle, derived statuses are created to provide a more meaningful representation of the encounter's outcome. This is particularly useful in analytical contexts where you want to filter or categorize encounters based on their completion state efficiently. By using the "DerivedEncounterStatus" column, users can ensure that they are interpreting the encounter status correctly, reflecting only those visits that are recognized as truly completed.

Other options might represent different states or concepts within the data model, but they do not specifically categorize the completion of office visits as accurately as the derived status. Understanding how these statuses are defined and when to use them is crucial for analyzing healthcare data effectively.
