Prior research has demonstrated barriers to the workup and management of primary hyperparathyroidism. As recent data have suggested that patient and practitioner sex concordance is associated with lower surgical complications, we sought to evaluate the effect of sex concordance on referral for primary hyperparathyroidism. We queried an institutional database for patients with first-incident hypercalcemia and subsequent biochemical evidence of primary hyperparathyroidism between 2010 and 2018. Primary care practitioner and endocrinologist sex, laboratory values, and complications of primary hyperparathyroidism were collected. Sex concordance (male patient/male practitioner or female patient/female practitioner) was evaluated as a binary predictor of specialist evaluation using logistic regression and Cox proportional hazards modeling. Among 1,100 patients, mean age was 62.5 (standard deviation 13.6), and 74% were female sex. Primary care practitioner sex was 52% female, and 63% of patients had sex concordance with their primary care practitioner. Endocrinologist sex was 59% female, and 45% of patients had sex concordance with their endocrinologist. Patients with sex concordance with their primary care practitioner (70 vs 80%, P = .001) and endocrinologist (71 vs 82%, P < .001) were less likely to be female sex compared to those with discordance. After adjusting for demographics and clinical covariates, those patients with primary care practitioner sex concordance had 32% higher odds of endocrinologist evaluation (odds ratio 1.32, 95% confidence interval 1.003-1.734, P = .047). Similarly, those patients with endocrinologist sex concordance had a 48% higher rate of surgeon evaluation (hazard ratio 1.48, confidence interval 1.1-2.0, P = .009). Stratified analysis revealed that sex discordance reduced the rate of surgeon referral for female patients (hazard ratio 0.63, confidence interval 0.44-0.89, P = .008) but not male patients (hazard ratio 1.06, CI 0.58-1.93, P = .861). Sex discordance between patients and their health care professionals may contribute to under-referral in primary hyperparathyroidism. Further evaluation of the effect of patient and practitioner identities on communication and decision-making in surgery are needed.
