Cost-effectiveness in transient hypocalcemia post-thyroidectomy

Research output: Contribution to journalArticlepeer-review


Background: Three different strategies to manage transient hypocalcemia after total thyroidectomy were compared to evaluate cost-effectiveness. The reliability of total serum calcium (TSCa), ionized calcium (ICa), and intact parathyroid hormone (iPTH) were investigated to achieve this goal. Methods: A multicenter, prospective randomized study was carried out with 169 patients. The strategies were “preventive” (oral calcium + vitamin D supplementation), “reactive” (therapy in hypocalcemia), and “predictive” (therapy if iPTH <10 pg/mL). Results: TSCa had higher accuracy in identifying patients who developed hypocalcemia-related symptoms than ICa (84.6% vs 50.0%). TSCa 24 h after surgery showed 24.8% of patients with hypocalcemia, whereas TSCa 48 h after surgery identified a further 10.6% with hypocalcemia (only in the “reactive” and “predictive” groups). iPTH showed low sensitivity as a predictor of hypocalcemia. Between the 3 groups, there was no significant difference in hospitalization time or number of symptomatic hypocalcemic patients. Interestingly, the cost-per-patient was significantly different among the groups. Conclusions: None of the discussed strategies allowed for early discharge of patients without any risk of transient hypocalcemia. The “preventive” strategy was the most cost-effective, despite overtreatment.
