Objectives To determine: (1) the accuracy of cytology scientists at assessing specimen adequacy by rapid on‐site evaluation ( ROSE ) at fine needle aspiration ( FNA ) cytology collections; and (2) whether thyroid FNA with ROSE has lower inadequacy rates than non‐attended FNA s. Methods The ROSE of adequacy for 3032 specimens from 17 anatomical sites collected over a 20‐month period was compared with the final report assessment of adequacy. ROSE was performed by 19 cytology scientists. The report profile for 1545 thyroid nodules with ROSE was compared with that for 1536 consecutive non‐ ROSE thyroid FNA s reported by the same cytopathologists during the study period. Results ROSE was adequate in 75% (2276/3032), inadequate in 12% (366/3032) and in 13% (390/3032) no opinion was rendered. Of the 2276 cases assessed as adequate by ROSE , 2268 (99.6%) were finally reported as adequate for assessment; eight specimens had adequacy downgraded on the final report. Fifty eight per cent of cases with a ROSE assessment of inadequate were reported as adequate (212/366), whereas 93% (363/390) with no opinion rendered were reported as adequate. The overall final report adequacy rate for the 3032 specimens was 94% (2843/3032). Confirmation of a ROSE of adequacy at reporting was uniformly high amongst the 19 scientists, ranging from 98% to 100%. The inadequacy rate for thyroid FNA s with ROSE (6%) was significantly ( P < 0.0001) lower than for non‐ ROSE thyroid FNA s (17%). A significantly ( P = 0.02) higher proportion of adequate ROSE thyroid specimens was reported with abnormalities, compared with non‐ ROSE thyroid collections. Conclusions Cytology scientists are highly accurate at determining specimen adequacy at ROSE for a wide range of body sites. ROSE of thyroid FNA s can significantly reduce inadequate reports.
