Abstract

Rapid on-site evaluation (ROSE) of endobronchial ultrasound guided transbronchial needle aspirates (EBUS-TBNA) increases diagnostic accuracy but in many institutions requires a specialist pathologist. This study aimed to determine if medical scientists or respiratory registrars could adequately perform ROSE to determine sufficiency of EBUS samples. ROSE was performed on the first two EBUS-TBNA passes per patient by a pathologist, a medical scientist and two respiratory registrars. The medical scientists involved had all previously performed ROSE on over 50 procedures. The two respiratory registrars received cytology education from a pathologist in four separate hour-long training sessions. Each ROSE reviewer recorded whether each sample was sufficient or insufficient. Pathologist interpretation was taken as gold standard. Specific diagnosis was not required. Final diagnosis and the total number of passes were also recorded. This study recruited 25 patients (50 passes) for statistical evaluation. Assessment by specialist pathologists deemed 16/50 (32%) to be sufficient and 34/50 (68%) insufficient respectively. Medical scientists were 90% concordant with the pathologist (K =0.774; 95% CI, 0.587-0.961). The two respiratory regist...Continue Reading
