About Autocoding


Autocoding is an automated process that assigns a code by matching the properties of a pending Code Request and entries in the assigned Synonym List. Synonym Lists are stored records of previously coded Code Requests that are used to inform autocoding (learn more about Synonym Lists here). During autocoding, Vault Coder evaluates Code Requests that are pending coding and compares their coding properties to Synonyms in the Synonym List. If there is an exact match between the code request’s properties and the patterns stored within the Synonym List, Vault Coder automatically assigns the corresponding code to the Code Request. If there is no match, Vault Coder attempts to autocode from the assigned dictionary release (when Autocoding from Dictionary is enabled for a study). Autocoding drastically reduces the workload for clinical coders and provides the user with Autocoding and Suggestions that are constantly up-to-date with evolving Synonym Lists.

How Does Vault Coder Autocode?

Vault Coder autocodes when the Verbatim of the Code Request and the Verbatim of a Synonym List entry are an exact match. If the Verbatim of the Code Request and the Verbatim of the Synonym List are not exactly matching but close to matching, the Synonym List Record will be assigned as a Suggestion. Vault automatically uses the Verbatim for autocoding. A study designer can also configure which additional properties are used for autocoding and suggestions. For WHODrug forms, Indication and Route are available, and a study designer can choose one or both.

Adding to Synonym Lists

Coder users can add a Code Request as a record in a Synonym List as they are coding, if they want future matching records to be assigned the same code during autocoding. To do this, toggle Add to Synonym List? to Y (Yes) in the Coding panel before clicking Code or Code + Next.

Coding administrators can create Synonym Lists and assign them to Forms for autocoding from Coder Tools. See Managing Synonym Lists for details.

Refreshing Coding Requests

Vault Coder autocodes automatically, so you may need to refresh the Code Request table with the Refresh button to see the latest data. A warning icon and message will appear when your data needs to be refreshed. Refreshing also reapplies any filters that were previously selected.
