ABSTRACT
The process of developing, implementing, and refining a registry data validation system is integral to optimal trauma registry operations. Describing registrar skill and proficiency in a manner that was once subjective can be replaced with objective assessment through the use of concrete rating guidelines and examples. The ability to standardize the evaluation of each registry abstract becomes the foundation for analyzing the overall accuracy of registry data. Key to the process is incorporating the validation rating tool as part of the data abstract. If properly implemented, the methodology described becomes a practical means for accuracy reporting, peer benchmarking, orientation and training, and performance management.
