BACKGROUND: Primary hyperparathyroidism is associated with substantial morbidity, including osteoporosis, nephrolithiasis, and chronic kidney disease. Parathyroidectomy can prevent these sequelae but is poorly utilized in many practice settings.METHODS: We performed a retrospective cohort study using the national Optum de-identified Clinformatics Data Mart Database. We identified patients aged =35 with a first observed primary hyperparathyroidism diagnosis from 2004 to 2016. Multivariable logistic regression was used to determine patient/provider characteristics associated with parathyroidectomy.RESULTS: Of 26,522 patients with primary hyperparathyroidism, 10,101 (38.1%) underwent parathyroidectomy. Of the 14,896 patients with any operative indication, 5,791 (38.9%) underwent parathyroidectomy. Over time, there was a decreasing trend in the rate of parathyroidectomy overall (2004: 54.4% to 2016: 32.4%, P < .001) and among groups with and without an operative indication. On multivariable analysis, increasing age and comorbidities were strongly, inversely associated with parathyroidectomy (age 75-84, odds ratio 0.50 [95% confidence interval 0.45-0.55]; age =85, odds ratio 0.21 [95% confidence interval 0.17-0.26] vs age 35-49; Charlson Comorbidity Index =2 vs 0 odds ratio 0.62 [95% confidence interval 0.58-0.66]).CONCLUSION: The majority of US privately insured patients with primary hyperparathyroidism are not treated with parathyroidectomy. Having an operative indication only modestly increases the likelihood of parathyroidectomy. Further research is needed to address barriers to treatment and the gap between guidelines and clinical care in primary hyperparathyroidism.
