Background: Thyroid nodules are very common, and the European Thyroid Association (ETA) recently issued high-quality guidelines to standardize their management. However, the extent of guideline implementation and the barriers to adherence remain unclear. This study evaluates the application of the guidelines and identifies obstacles to their adoption among Greek endocrinologists.
Methods: Between November 2023 and April 2024, members of the Hellenic Endocrine Society (HES) completed a web-based survey on the management of a 2.5 cm thyroid nodule with fine-needle aspiration (FNA) cytology results of Atypia of Undetermined Significance (AUS). The scenarios varied by the nodules sonographic risk classification: intermediate (EU-TIRADS 4) or high (EU-TIRADS 5). Participants also provided demographic information and reasons for non-adherence to the guidelines.
Results: The survey had a 25% response rate. For an EU-TIRADS 4 nodule with AUS cytology, 61% of respondents chose to repeat FNA, while only 23% opted to do so for an EU-TIRADS 5 nodule with AUS cytology, despite the 2023 ETA guidelines recommending repeat FNA in both scenarios. More experienced endocrinologists were less likely to select repeat FNA and more inclined toward total thyroidectomy in the EU-TIRADS 4 scenario. In contrast, experience had no significant impact on decision-making for the EU-TIRADS 5 scenario. Key barriers to guideline adherence included skepticism about the recommendations, limited access to reliable neck ultrasonography and molecular testing, and a shortage of high-volume surgeons.
Conclusions: Greek endocrinologists frequently deviate from the 2023 ETA guidelines for managing thyroid nodules with indeterminate cytology, citing challenges that may also affect clinicians in other countries. These findings highlight the importance of developing strong implementation strategies alongside guideline releases, particularly in anticipation of the upcoming American Thyroid Association guidelines for managing thyroid nodules in adults.
