Association between Magnesium Disorders and Hypocalcemia following Thyroidectomy

Area of Science:

• Endocrinology
• Surgical Outcomes
• Health Services Research

Background:

• Postoperative hypocalcemia is a common complication following thyroid surgery.
• Understanding its risk factors and impact on healthcare resource utilization is crucial.

Purpose of the Study:

• To identify factors associated with postoperative hypocalcemia after thyroid surgery.
• To analyze the relationship between hypocalcemia, length of hospitalization, and healthcare costs.

Main Methods:

• Retrospective analysis of Nationwide Inpatient Sample discharge data (2001-2010).
• Inclusion of 620,744 patients undergoing thyroid surgery.
• Cross-tabulations and multivariate regression modeling were employed.

Main Results:

• Hypocalcemia occurred in 6% of patients, with higher incidence in women, younger patients, and those undergoing total thyroidectomy.
• Disorders of magnesium metabolism were strongly associated with hypocalcemia (OR, 12.71).
• Both hypocalcemia and magnesium disorders significantly increased length of stay and costs.

Conclusions:

• Disorders of magnesium metabolism are an independent risk factor for postthyroidectomy hypocalcemia.
• Magnesium disorders are linked to substantially increased hospital length of stay and costs.
• Early identification and management of magnesium disorders may mitigate adverse outcomes.
