- Abstract
Objectives Rapid on-site evaluation ( ROSE) of endobronchial ultrasound-guided transbronchial needle aspiration ( EBUS- TBNA) followed by a subsequent preliminary adequacy assessment and a preliminary diagnosis, was performed at Aarhus University Hospital by biomedical scientists ( BMS). The aim of this study was to evaluate the BMS accuracy of ROSE adequacy assessment, the preliminary adequacy assessment and the preliminary diagnosis as compared with the cytopathologist-rendered final adequacy assessment and final diagnosis. Methods The BMS-rendered assessments for 717 sites from 319 consecutive patients over a 4-month period were compared with the cytopathologist-rendered assessments. Comparisons of adequacy and preliminary diagnoses were based on inter-observer Cohen's Kappa coefficient with a 95% confidence interval ( CI). Results Strong correlations between ROSE and final adequacy assessments [Kappa coefficient of 0.90 ( CI: 0.85-0.96)] and between the preliminary and final adequacy assessments [Kappa coefficient of 0.93 ( CI: 0.87-0.99)] were found. As for the correlation between the preliminary and final diagnoses, the Kappa coefficient was 0.99 ( CI: 0.98-1). Conclusion Both ROSE and preliminary adequacy assessments as well as preliminary diagnoses, all performed by BMS, were highly accurate when compared with the final assessment by the cytopathologist.
