2024Q3 Data Release Notes

1. New Data Sources Available

Health Verity Comprehensive Claims

The HealthVerity Comprehensive Claims (Closed Claims Enrollment) derived data set contains de-identified linked patient information from select private data providers participating in the HealthVerity marketplace. This data extract includes 3 data sources across medical and pharmacy closed claims data, 9 sources providing open medical claims, 8 sources providing open pharmacy claims, and 1 source providing linked death data.

During the transformation to the OMOP CDM, only patients with enrollment in one of the two closed claims sources are included. The reasoning behind this is twofold. First, by using only patients with closed claims enrollment there is a high probability that any interaction with the health care system will be recorded. Data from the other linked sources, like laboratory data, becomes additional clinical context while retaining the low likelihood that adverse events would be missing from the record altogether. Second, the time during which a person is enrolled in a closed claims system provides more accurate person-time calculations.

2. General Updates

Mosunetuzumab

The drug mosunetuzumab recently came to market and it was given a HCPCS code that was used previously and discontinued in 2014 (J9350). Because of this reuse, mosunetuzumab was being incorrectly mapped to the drug topotecan. We introduced a vocabulary update that identifies this reuse and assigns the appropriate standard concept based on date.

3. Source Specific Updates

Optum Extended

  • Race and Ethnicity Changes: Optum Extended recently updated their source of race and ethnicity data. It now uses self-reported data that splits these values into two variables. The mapping logic was updated to reflect this change and all details can be found here: https://ohdsi.github.io/ETL-LambdaBuilder/Optum%20Clinformatics/Optum_person.html#mapping-race

  • Death Changes: A small number of patients in Optum Extended Date of Death (DOD) had a death date that occurred prior to their OBSERVATION_PERIOD_START_DATE. In consulting with the vendor we learned that this is likely an error in the death date linkage so those deaths were removed.

Optum EHR

  • Future Dates: Some patient's OBSERVATION_PERIOD_END_DATE occur in the future. This is due to a data quatlity error in the native data. In these cases the OBSERVATION_PERIOD_END_DATE is set to the source release date.

CDM to CDM Builder

  • The build logic was update to remove patients that do not have a valid gender. Only patients with a Male or Female value are kept.
