Purpose: The most common indications for total thyroidectomy (TT) in children are malignancy and thyrotoxicosis due to Graves' disease (GD). However, the incidence of patients with GD among patients undergoing TT is unknown. This study aims to examine trends in pediatric TT.
Materials and methods: The US Agency for Health Research and Quality Healthcare Cost and Utilization Project (HCUP) Kids' Inpatient Database (KID) was queried to identify patients who underwent TT between 1997 and 2019. Weighted national estimates were obtained. Statistical analysis was completed using univariate logistic regression and one-sided Mann-Kendall Test.
Results: An estimated 4803 pediatric patients underwent TT within the study years. GD was the indication in 25 % of cases. Mann-Kendall testing showed a trend toward an increasing proportion of TT for GD without reaching statistical significance (z = 1.3609, S = 12, p = 0.0688). Statistically significant univariate associations were found among those who underwent thyroidectomy for GD compared to other indications, as they were more likely to be female (β = 0.286, 95 % CI [0.058, 0.514], p = 0.014), Black, or Hispanic (β = 1.392 [1.064, 1.721], p < 0.001; and β = 0.562 [0.311, 0.814], p < 0.001, respectively). Additionally, they were less likely to have private insurance (β = -0.308 [-1.076, -0.753], p = 0.002) and more likely to live in a ZIP code associated with a median household income below the 50th percentile (β = 0.190 [0.012, 0.369], p = 0.036). The associations with the female sex, Black race, and Hispanic race persisted in multivariate analysis.
Conclusion: GD appears to be an increasingly prevalent indication for TT. Patient characteristics differ from those who undergo TT for other diagnoses.
