Cytologic-histologic correlation

Abstract

The process of cytologic-histologic correlation is highly valuable to the fields of both cytopathology and surgical pathology, because correlation provides a wealth of data that may be used to improve diagnostic testing and screening processes. In this study, overall improvement appeared to be driven largely by improvement in preanalytic Papanicolaou (Pap) test sampling, because longer institutional participation also was associated with improved sampling sensitivity. The authors hypothesized that Pap test sampling may have improved secondary to the introduction of liquid-based technology, which was implemented in many laboratories during the study time frame. Through the performance of continuous data tracking and retrospective root cause analysis to identify factors that may have influenced any observed changes in performance indicators, institutions may learn which initiatives are successful or unsuccessful. The future of correlation lies in the standardization of methods, the development of more formal and rigorous root cause analysis processes to determine system components underlying correlation discrepancies, and the active use of correlation data to redesign testing and screening processes for quality and patient safety improvement.
