Compliance with guidelines for thyroid nodule evaluation.

Area of Science:

• Endocrinology
• Oncology
• Diagnostic Imaging

Background:

• Solitary thyroid nodules require accurate diagnostic evaluation.
• The American Association of Clinical Endocrinologists (AACE) provides guidelines for assessing solitary thyroid nodules.
• Adherence to established clinical guidelines is crucial for effective patient management.

Purpose of the Study:

• To assess the clinical application of AACE guidelines for solitary thyroid nodule assessment.
• To evaluate the impact of endocrinologist consultation on diagnostic workup patterns.
• To identify potential areas for improving the diagnostic pathway for thyroid nodules.

Main Methods:

• Retrospective review of 89 patients with solitary thyroid nodules over a 2-year period.
• Analysis of diagnostic tests performed, including ultrasonography, fine-needle aspiration (FNA) biopsy, and thyroid scans.
• Comparison of workup patterns between patients with and without endocrinologist consultation.

Main Results:

• Thyroid scans were overutilized (90% of patients) with a high rate of normal findings (21%).
• Fine-needle aspiration (FNA) biopsy was performed in 65% of patients, but was the sole test in only 9%.
• Endocrinologist consultation significantly increased the likelihood of FNA biopsy (82% vs. 29%, P<0.001).

Conclusions:

• Current clinical practice shows incomplete implementation of AACE guidelines for solitary thyroid nodules.
• Endocrine referral positively influences the utilization of FNA biopsy, a key diagnostic tool.
• Reducing reliance on thyroid scans and promoting early endocrinologist referral may enhance cost-effectiveness and diagnostic accuracy.
