Using a Digital Implant Catalog Improves Data Quality and Reduces Administrative Burden in the Dutch Breast Implant Registry

Background: Correct registration of implant characteristics is essential to monitor implant safety within implant registries. Currently, in the nationwide Dutch Breast Implant Registry (DBIR), these characteristics are being registered manually by plastic surgeons, resulting in administrative burden and potentially incorrect data entry. Objectives: This study evaluated the accuracy of manually registered implant data, possible consequences of incorrect data, and the potential of a Digital Implant Catalog (DIC) on increasing data quality and reducing the administrative burden. Methods: Manually entered implant characteristics (fill, shape, coating, texture) of newly inserted breast implants in the DBIR, from 2015 to 2019, were compared with the corresponding implant characteristics in the DIC. Reference numbers were employed to match characteristics between the 2 databases. The DIC was based on manufacturers' product catalogs and set as the gold standard. Results: A total of 57,361 DBIR records could be matched with the DIC. Accuracy of implant characteristics varied from 70.6% to 98.0%, depending on the implant characteristic. The largest discrepancy was observed for "texture"and the smallest for "coating."All manually registered implant characteristics resulted in different conclusions about implant performance compared with the DIC (P < 0.01). Implementation of the DIC reduced the administrative burden from 14 to 7 variables (50%). Conclusions: Implementation of a DIC increases data quality in the DBIR and reduces the administrative burden. However, correct registration of reference numbers in the registry by plastic surgeons remains key for adequate matching. Furthermore, all implant manufacturers should be involved, and regular updates of the DIC are required.
