Which is an example of a reabstracting study?

B is the correct answer because a reabstracting study involves having a qualified staff member evaluate or abstract cases that have already been reviewed or abstracted by other personnel. This process is significant for validating the accuracy and consistency of previously collected data. In a reabstracting study, the focus is on comparing the new abstractions with the original ones to identify discrepancies, assess quality, and ensure adherence to defined standards in data collection and abstraction processes.

The other options present different activities but do not align with the concept of reabstracting. For instance, reviewing an abstract of a trainee involves feedback and oversight but does not constitute a re-evaluation of previously abstracted cases. Team meetings about data quality may enhance the overall understanding and implementation of quality standards but do not involve the hands-on process of reabstracting. Documenting the number of abstracts completed by trainees is a measure of productivity rather than an assessment of abstract quality or accuracy, which is the central focus of a reabstracting study.
