A Parathyroid Hormone-Guided Calcium and Calcitriol Supplementation Protocol Reduces Hypocalcemia-Related Readmissions Following Total Thyroidectomy.
Endocrine Practice 2023 April
OBJECTIVE: To determine the effect of a 4-hour postoperative serum parathyroid hormone (PTH)-guided calcium (Ca) and calcitriol supplementation protocol on the incidence of hypocalcemia and hospital readmissions in patients undergoing total thyroidectomy.
METHODS: This was a single-institution, retrospective chart review of patients who underwent total thyroidectomy; 148 and 389 of the patients underwent surgery prior to and after the protocol implementation, respectively. The risk of hypocalcemia was stratified as low (PTH level of >30 pg/mL), medium (15-30 pg/mL), and high (<15 pg/mL), using serum PTH values obtained 4 hours postoperatively. Hypocalcemia was defined as a total serum Ca level of <8 mg/dL. Baseline demographic and operative characteristics and postoperative outcome were recorded for both groups. The Fisher exact test and Wilcoxon rank sum test were used to compare the characteristics of the 2 groups. A multivariate logistic regression model was applied to account for potentially confounding variables.
RESULTS: Postoperative hypocalcemia occurred significantly less frequently in the protocol group compared with that in the preprotocol group (10.3% vs 20.9%, P = .002). The reduction in hypocalcemia in the protocol group was observed in both patients with (16.3% vs 25.6%) and without (8.4% vs 19.3%) cervical lymph node dissection. The protocol group had a significantly lower incidence of hospital readmission events than the preprotocol group (1.0% vs 4.7%, P = .013).
CONCLUSION: Compared with a historical cohort, a PTH-guided protocol for Ca and calcitriol supplementation significantly reduces the postoperative hypocalcemia and hospital readmission rates in patients undergoing total thyroidectomy.
