Differences in Perioperative Metrics by Race and Ethnicity and Insurance After Pelvic Fracture: A Nationwide Study.

BACKGROUND

Disparities in orthopedic trauma care have been reported for racial-ethnic minority and socially disadvantaged patients. We examined differences in perioperative metrics by patient race and ethnicity and insurance after pelvic fracture in a national sample in the United States.

MATERIALS AND METHODS

The 2016-2019 National Inpatient Sample was queried for White, Black, and Hispanic patients 18 to 64 years old with private, Medicaid, or self-pay insurance who underwent non-elective pelvic fracture surgery. Associations between combined race and ethnicity and insurance subgroups and perioperative metrics (time to surgery, length of stay, inhospital complications, institutional discharge) were assessed using multivariable generalized linear and logistic regression models. Adjusted percent differences or odds ratios (ORs) were reported.

RESULTS

A weighted total of 14,375 surgeries were included (68.8% in White patients, 16.1% in Black patients, and 15.1% in Hispanic patients; 60.0% private insurance, 26.3% Medicaid, and 13.7% self-pay). Compared with White patients with private insurance, all Black insurance subgroups had longer length of stay (+15.38% to +38.78%, ≤.001), as did Hispanic patients with Medicaid (+28.03%, <.001), White patients with Medicaid (+13.08%, <.001), and White patients with self-pay (+9.47%, =.04). Additionally, compared with White patients with private insurance, decreased odds of institutional discharge were observed for all patients with self-pay (OR, 0.24-0.37, <.001) as well as White patients with Medicaid (OR, 0.70, =.003) and Hispanic patients with Medicaid (OR, 0.57, =.002). There were no significant adjusted associations between race and ethnicity and insurance subgroups and in-hospital complications or time to surgery.

CONCLUSION

These differences in perioperative metrics, primarily for Black patients and patients with self-pay insurance, warrant further examination to identify whether they reflect disparities that should be addressed to promote equitable orthopedic trauma care. [. 2024;47(5):e233-e240.].
