AIM: To compare the opinions of practitioners in primary care with those of thyroid specialists in Germany on the management of solitary thyroid nodules (Papillon 2005). METHODS: Questionnaires were filled in by 2,191 practitioners and 297 thyroid specialists between June 1 and September 30, 2005. The test cases and their modifications described a solitary thyroid nodule of 2-3 cm with different levels of thyroid function and a hypoechogenic nodule of 1 cm in diameter. RESULTS: TSH determination and sonography were found to be standard procedures, followed by scintigraphy (selected by 84.7% of practitioners and 95.1% of specialists, p <0.001) and fine needle aspiration cytology (54.5% of practitioners, 57.4% of specialists). For a hypoechogenic nodule calcitonin determination was advocated by 54.0% of endocrinologists and by 32.2% of nuclear medicine physicians (p <0.001). A euthyroid solitary thyroid nodule would be treated medically by 77.8% of practitioners and by 85.7% of specialists, the combination of levothyroxine and iodine being clearly preferred (60.9% of practitioners and 67.1% of specialists). For a hyperfunctioning nodule the preference of radioiodine therapy was significantly higher in the specialist group (88.8%) than among the practitioners (52.2%). CONCLUSIONS: The main differences of opinion between practitioners and specialists focused on calcitonin screening and referral to radioiodine therapy.
