Ethnic and economic disparities effect on management of hyperparathyroidism.

BACKGROUND

Successful parathyroidectomy requires advanced surgeon experience. We aim to examine population characteristics at risk of being managed by low-volume surgeons.

METHODS

A cross-sectional study was performed utilizing the Nationwide Inpatient Sample database, 2004 to 2009. The study population included adult inpatients who underwent parathyroidectomy for primary hyperparathyroidism.

RESULTS

A total of 3,503 discharge records were included. Men, Hispanics, and those with Medicaid/Medicare health coverage were more likely to be managed by low-volume surgeons (P < .05 each). Low-volume surgeons were more likely to operate in rural (odds ratio [OR], 3.99; 95% confidence interval [CI], 1.95 to 8.16; P < .001) or nonteaching hospitals (OR, 2.15; 95% CI, 1.42 to 3.27; P < .001). Southern region of the United States had a high prevalence of low-volume surgeons compared with other regions (Southern: 51.3%, Northeast: 24.3%, Midwest: 25.6%, and West: 27.6%, P < .001). Operations by the low-volume surgeons associated with a higher risk of postoperative complications (OR, 1.81; 95% CI, 1.11 to 2.97) and a hospital stay more than 2 days (OR, 7.12; 95% CI, 3.75 to 13.45; P < .001).

CONCLUSIONS

Certain populations are at risk of management by low-volume surgeons based on their demographic and economic characteristics.
