Which Localizing Strategy is the Most Cost-Effective in Reoperative Primary Hyperparathyroidism?
JOURNAL OF SURGICAL RESEARCH(2024)
Abstract
Introduction: 2%-10% of patients with primary hyperparathyroidism (PHPT) who undergo parathyroidectomy develop persistent/recurrent disease. The aim of this study was to determine which preoperative localization method is most cost-effective in reoperative PHPT. Methods: Clinical decision analytic models comparing cost-effectiveness of localizing studies in reoperative PHPT were constructed using TreeAge Pro. Cost and probability assumptions were varied via Probabilistic Sensitivity Analysis (PSA) to test the robustness of the base case models. Results: Base case analysis of model 1 revealed ultrasound (US)-guided fine-needle aspiration with PTH assay as most cost-effective after localizing US. This was confirmed on PSA of model 1. Model 2 showed four-dimensional computed tomography (4D -CT) as most costeffective after negative US. If not localized by US, on PSA, 4D -CT was the next most costeffective test. Conclusions: US-guided FNA with PTH is the most cost-effective confirmatory test after US localization. 4D -CT should be considered as the next best test after negative US. (c) 2024 Elsevier Inc.
