title: Cytotechnologist screening of fine-needle aspiration specimens: impact on turnaround time and diagnostic accuracy.
abstract: Fine-needle aspiration (FNA) is widely utilized due to its short turnaround time (TAT), diagnostic accuracy, and low cost. Controversy exists as to what role cytotechnologists should play in evaluation of FNAs. Some authorities believe all FNAs should be screened by cytotechnologists while others believe that cytotechnologist review is unnecessary. Sixty sequentially performed FNAs without initial review by cytotechnologists were selected from the files of the University of Utah, Department of Pathology. The slides were obtained along with the associated final diagnoses. The slides were reviewed by cytotechnologists given patient history and specimen site but were blinded to the initial pathologist's diagnoses. The initial cytopathologist's diagnoses and subsequent cytotechnologists' diagnoses were recorded and correlated. TATs for these cases were calculated and compared with TATs in a second set of randomly selected FNAs where cytotechnologists had initially screened the cases. Correlation of initial cytopathologists' diagnoses with those of cytotechnologists' revealed no instances where cytotechnologists identified diagnostically significant findings not noted by the original pathologist. TAT for the FNAs reviewed only by a cytopathologist averaged 25.9 hours with a mode of 6 hours. TATs for cases with initial cytotechnologist screening averaged 44.1 hours with a mode of 25 hours. Pre-sign-out screening of FNA specimens by cytotechnologists does not appear to increase detection of cytologic abnormalities. Cytotechnologist screening does substantially increased TAT from a mean of 26 hours to approximately 44 hours. Such an extensive delay may reduce the overall clinical utility of the FNA technique.
