OID/RID dictionary (Item Master) Updates
Whether the compendium consists of only a data set from an internal LIS, an external reference lab, or a synchronized version of both; it is always a best practice to keep the OID and RID dictionary as in sync as possible with the upstream system. After the initial build or bulk load of the compendium prior to go-live, look to establish a process where weekly, monthly, or quarterly updates are communicated so that update, addition, and inactivation entries can be made. In some cases when codes or mnemonics remain the same, but descriptions change, the provider or user can develop the impression that the systems are out of sync.
Sometimes this level of diligence is not directly required, such as circumstances where the site may be utilizing the dictionary interfaces in CxR that have the ability to "auto-build" these dictionaries on the fly or real time.
