Assessment of thyroid nodule risk stratification knowledge and utilization among Polish physicians: a pilot study

Purpose: Ultrasonography is the primary diagnostic tool for evaluating thyroid nodules. The Thyroid Imaging Reporting & Data System (TIRADS) aims to standardise assessment and reduce fine-needle aspiration biopsies through risk stratification. This pilot study examined knowledge and utilisation of TIRADS among Polish physicians, their perception of the usefulness of TIRADS application and the extent of knowledge of individual nodule features included.

Material and methods: An internet-based questionnaire about TIRADS use in clinical practice was sent out to Polish Ultrasound Society members. Information on the responder's experience with thyroid ultrasound and knowledge and use of TIRADS was assessed and analysed.

Results: Out of 159 physicians, 66.6% did not use TIRADS despite 43.4% being aware of its existence. EU-TIRADS was the most commonly adopted classification (50.9%). Participants who adopted TIRADS were younger (p = 0.047) and more likely to be radiologists (p < 0.01). TIRADS use was more prevalent in university clinical hospitals (p = 0.02), among physicians doing thyroid ultrasound as their primary professional activity (p < 0.01), those performing > 100 thyroid ultrasound examinations per year (p < 0.01) and those involved with thyroid fine-needle aspiration biopsy (p < 0.01). The purposes of TIRADS adoption (p < 0.01) and included imaging features (p < 0.01) were more accurately recognized by TIRADS users.

Conclusions: TIRADS utilization among Polish clinicians is limited, despite awareness of the classification's existence. Knowledge of TIRADS components and the purpose of its application among users is satisfactory. Further training and TIRADS adoption should be encouraged, especially in the light of the recent EU-TIRADS-PL guidelines recommended by the Polish Scientific Societies.
