Lithium-associated primary hyperparathyroidism:: An evaluation of screening and referral patterns in a southeastern veteran population.

Background: Long-term lithium therapy has a well-established but under-recognized association with primary hyperparathyroidism. Rates of hypercalcemia, screening for primary hyperparathyroidism, and referral for parathyroidectomy were evaluated among United States veterans on long-term lithium therapy.

Methods: Patients undergoing chronic long-term lithium therapy (>12 months) were identified from 1999 to 2022.
