Fine needle aspiration (FNA) cytology is a basic diagnostic technique used to investigate superficial and deep swellings. Rapid on-site evaluation (ROSE) using toluidine blue (TB) is easily available, cheap, cost-effective, can be used both for testing adequacy and giving provisional diagnosis. To evaluate the role of ROSE using toluidine blue staining in arriving at a diagnosis in comparison to routine stains. A total of 1500 cases of FNA of palpable swellings from sites like salivary gland, breast, thyroid, lymph node, and soft tissue lesions [non-image guided] during a 9-month period were studied. All the cases were evaluated by ROSE using toluidine blue stain and routine Giemsa/PAP staining. The results were compared in each case. Only 2% cases proved inadequate on TB, Giemsa and PAP combination, commonest site of inadequacy being lymph node. Adequate sample was obtained within two passes in 92.5% cases. The turnaround time (TAT) was 1 day in 96.4% of cases. The average time for making a provisional diagnosis on TB was 3 minutes. There was 99.2% concordance between TB and final cyto-diagnosis. Validity parameters: sensitivity 98%, specificity 100%, positive predictive value 100%, negative predictive value 99.8%, efficacy 99.2% and false negative 1.94%. ROSE using toluidine blue is a reliable means of demonstrating sample adequacy, for making a provisional diagnosis and guiding collection of diagnostic material for microbiology, immunocytochemistry (ICC), cell block and molecular testing etc. The technique is easy enough for general laboratories to incorporate into their routine practice. ROSE can be called as the "frozen section of cytology".
Rapid onsite evaluation: A comparison of cytopathologist and pulmonologist performance
Cancer cytopathology, 2015
Rapid onsite evaluation (ROSE) has several potential benefits but also can prolong procedures if one must wait for a cytopathologist, and it can involve a considerable time commitment on the part of the cytopathologist. At the University of Arkansas for Medical Sciences, interventional pulmonologists have routinely reviewed cytology specimens. This study was performed to determine prospectively how accurately pulmonologists could perform ROSE and whether they could contribute to the efficiency of the process. For sequential cases, the procedural pulmonologist documented a ROSE reading before the reading by the cytopathologist. Readings were compared between the two for agreement and for accuracy. The time commitment for the cytopathologist was also recorded. One hundred sixty-four sites were biopsied in 102 patients. With respect to onsite adequacy, there was a high level of concordance between pulmonology and cytopathology as evidenced by the κ score ( ± standard error) of 0.72 ± 0...

Nongynecologic cytology (NGC) practices are expected to expand relative to gynecologic cytology. The College of American Pathologists attempts to track practice patterns in NGC using a self-reported questionnaire. To analyze self-reported laboratory staffing and practices from a 2010 survey relating to NGC specimens, stains, preparation, procedures, and ancillary testing. The "NGC 2010 Demographics and Supplemental Questionnaire: Current Nongynecologic Practices in Cytopathology Laboratories" was mailed to 2059 laboratories. Survey response rate was 51% (1048 of 2059), predominantly from voluntary, nonprofit hospitals, where NGC samples were reviewed in nontraining settings by pathologists without American Board of Pathology Added Qualification in Cytopathology. Cytotechnologists reviewed NGC cases in 67.4% (675 of 1002) of laboratories. The annual mean and median volumes of NGC cases were 1927 and 858, respectively. Laboratories used more than one method to process NGCs; ...

BACKGROUND: Rapid on-site evaluation (ROSE) can increase adequacy and reduce needle passes in fine-needle aspiration cytology (FNAC) procedures. However, ROSE increases the cost of FNAC. Costs may be reduced if ROSE is performed by an alternate evaluator (AE), such as a cytotechnologist (CT), endoscopist, or pulmonologist, rather than a cytopathologist (CP). Studies have shown that AEs can perform ROSE with high accuracy but are generally not as accurate as CPs. The objective of this study was to evaluate the impact of AEs on the cost-effectiveness of ROSE. METHODS: A cost model, based on a mathematical sampling model, was developed. The cost model was used to compare the impact of the evaluator type on overall costs. RESULTS: CTs were likely to be cost-effective for simple procedures and were unlikely to be cost-effective for only the most complex procedures. The model demonstrated the tradeoff in cost savings from using AEs and the potential costs associated with repeated procedures due to the lower accuracy of AEs. CONCLUSIONS: The costeffectiveness of AEs is context-dependent. AEs can be cost-effective even if they are less accurate than CPs. AEs are likely to be cost-effective in most contexts Cancer Cytopathol 2018;126:839-845.
On-site adequacy evaluations performed by cytotechnologists
Cancer Cytopathology, 2011
BACKGROUND: Practice patterns regarding on-site assessment of the adequacy of image-guided fine-needle aspiration biopsies (FNABs) vary among laboratories, but in many laboratories primary responsibility rests with the cytotechnologists. On-site evaluation provides feedback on the need for additional passes and facilitates triaging of the specimen for time-sensitive ancillary studies. Prior studies have suggested that cytotechnologists can assess the initially obtained specimens correctly, but they are few in number and limited by small size. The purpose of this study was to assess the frequency with which our cytotechnologists were able to correctly assess specimens as adequate using a large-scale database that included a wide range of image-guided FNABs. METHODS: The frequency that on-site adequacy assessments of 5241 image-guided FNABs were correct was determined by correlating the cytotechnologists' assessments of adequacy with the final cytologic interpretation. An adequacy assessment was considered correct if the FNAB was ultimately reported as satisfactory and unequivocally benign or malignant. An adequate reading on a case that was ultimately reported as unsatisfactory, atypical, or suspicious was deemed ''incorrect.'' The effect of imaging modality was also analyzed. RESULTS: Of 5241 FNABs, 2784 (53%) were interpreted as adequate on site. Of these, 2637 (95%) were correctly considered adequate. Of the common biopsy sites sampled, the adequacy assessments for liver FNABs demonstrated the highest frequency for being correctly considered adequate (97%) and those for kidney FNABs showed the lowest (90%). Imaging modality had no effect on accuracy. CONCLUSIONS: Cytotechnologists are almost always correct when assessing initial FNAB samples as adequate. Cancer (Cancer Cytopathol) 2012;120:177-84. V

Double reading may be a valuable tool for improving the quality of patient care by restoring diagnostic errors before final sign-out, but standard double reading would significantly increase costs of pathology. The aim of this study was to assess the added value of routine double reading of defined categories of clinical cytology specimens by specialized cytopathologists. Specialized cytopathologists routinely re-diagnosed blinded defined categories of clinical cytology specimens that had been signed out by routine pathologists from January 2012 up to December 2013. Major and minor discordance rates between initial and expert diagnoses were determined, and both diagnoses were validated by comparison with same-site histological follow-up. Initial and expert diagnoses were concordant in 131/218 specimens (60.1 %). Major and minor discordances were present in 28 (12.8 %) and 59 (27.1 %) specimens, respectively. Pleural fluid, thyroid and urine specimens showed the highest major discordance rates (19.4, 19.2 and 16.7 %, respectively). Histological follow-up (where possible) supported the expert diagnosis in 95.5 % of specimens. Our implemented double reading strategy of defined categories of cytology specimens showed major discordance in 12.8 % of specimens. The expert diagnosis was sup-ported in 95.5 % of discordant cases where histological follow-up was available. This indicates that this double reading strategy is worthwhile and contributes to better cytodiagnostics and quality of patient care, especially for suspicious pleural fluid, thyroid and urine specimens. Our results emphasize that cytopathology is a subspecialization of pathology and requires specialized cytopathologists.
