Cytologic rapid on-site evaluation of transthoracic computed tomography-guided lung needle biopsies: who should perform ROSE? A cross-institutional analysis of procedural and diagnostic outcomes.

Introduction: Cytologic rapid on-site evaluation (ROSE) during minimally invasive biopsy procedures is an increasingly important service provided by cytopathology to increase diagnostic yield and appropriately triage cellular material. Although ROSE can be performed by cytopathologists, cytotechnologists, or cytopathology fellows, few studies have directly compared both procedural and diagnostic outcome measures among different ROSE personnel.

Materials And Methods: We evaluated all transthoracic computed tomography (CT)-guided lung biopsies in which ROSE was performed during a 1-year period at 2 academic institutions with similar patient populations and procedural methods: Dartmouth-Hitchcock Medical Center (DHMC) (where ROSE is performed by cytopathologists) and the Beth Israel Deaconess Medical Center (BIDMC) (where ROSE is rendered by either cytotechnologists or cytopathology fellows).

Reporting thyroid FNA before and after implementation of the Bethesda system-one institution's experience.

Background: The Bethesda System for Reporting Thyroid Cytopathology was published in 2008 and was implemented at Beth Israel Deaconess Medical Center (BIDMC) in June, 2010. Prior to this date, our diagnostic scheme was similar to the Bethesda System, except for the category of "Atypia/Follicular Lesion of Undetermined Significance" (AUS). This study evaluates the impact of the Bethesda System on the rate and the positive predictive value (PPV) of the diagnostic categories at BIDMC.
