Objective: To perform a comparative analysis of postthyroidectomy radioactive iodine ablation dosing with or without the implementation of a diagnostic whole-body scan in patients with well-differentiated thyroid cancer.
Study Design: Decision analysis model.
Setting: Hospital or ambulatory center.
Methods: A decision tree model was created to determine the cost-effectiveness of radioactive iodine ablation dosed with diagnostic whole-body scans versus empiric radioactive iodine ablation in patients with differentiated thyroid cancer undergoing postthyroidectomy ablation. The decision tree was populated with values from the published literature. Costs were represented by 2020 Medicare reimbursement rates (US dollars), and morbidity and survival data were used to calculate quality-adjusted life-years. The incremental cost-effectiveness ratio was the primary outcome.
Results: Empiric radioactive iodine dosing was the dominant economic strategy, producing 0.94 more quality-adjusted life-years while costing $1250.07 less than management with a diagnostic whole-body scan. Sensitivity analyses upheld these results except in cases involving a large discrepancy in successful ablation rates between the diagnostic and empiric treatment arms.
Conclusion: For patients with differentiated thyroid cancer requiring postthyroidectomy ablation, it is more cost-effective to administer radioactive iodine empirically.
