Rapid On-Site Evaluation With Telecytology Significantly Reduced Unsatisfactory Rates of Thyroid Fine-Needle Aspiration.

OBJECTIVES

We evaluated telecytology rapid on-site evaluation (ROSE) for thyroid ultrasound-guided fine-needle aspiration. To the best of our knowledge, this study is the first case-control clinical trial of thyroid telecytology.

METHODS

We introduced on-site ROSE in our institution's thyroid clinic for 6 months, followed by telecytology for 12 months. Our institution's ultrasound clinic, where ROSE is not provided, was used as a control group for each period.

RESULTS

Both groups had similar initial unsatisfactory rates (thyroid clinic: 8.8%; ultrasound clinic: 8.0%) before the study began. The thyroid clinic's unsatisfactory rate was significantly reduced to 1.6% after on-site ROSE (P = .001) and to 3.8% after telecytology ROSE (P = .010), with no significant difference between on-site and telecytology ROSE periods (P > .05). The ultrasound clinic's unsatisfactory rate was unchanged for both periods. Concordance between telecytology ROSE and final adequacy was 97% (κ = 0.699).

CONCLUSIONS

Telecytology ROSE reduces unsatisfactory rates for ultrasound-guided fine-needle aspiration without compromising patient care.
