Background:
Historically, humeral shaft fractures have been managed nonoperatively in a functional brace. However, recent studies suggest an increase in rates of operative fixation. Disparities in surgical management based on insurance status have been demonstrated across many orthopedic conditions. This study aimed to identify if a correlation exists between insurance coverage and the probability of undergoing operative fixation for a humeral shaft fracture.
Methods:
A retrospective examination of the National Readmissions Database from 2016 to 2021 was conducted. Patients diagnosed with isolated closed humeral shaft fractures were identified via International Classification of Disease, 10th Revision codes, and surgical interventions were identified using International Classification of Disease, 10th Revision procedural codes. Utilizing weighted data, a total of 56,468 patients with isolated closed humeral shaft fractures were identified, 25,075 (44.4%) of whom underwent operative fixation. A univariate analysis was conducted using Pearson's chi-square test to isolate variables for inclusion in a multivariable analysis. A binary logistic regression analysis was then employed to explore demographic and other pertinent factors. Findings were reported as odds ratios.
Results:
After controlling for social and demographic variables, patients with Medicaid (OR, 0.54; 95% CI, 0.50-0.58; P < .001), Medicare (OR, 0.64; 95% CI, 0.60-0.68; P < .001), and self-pay patients (OR, 0.75; 95% CI, 0.67-0.84; P < .001) were less likely to undergo operative fixation of humeral shaft fracture than those with private insurance.
Conclusions:
Patients without private insurance or those with no insurance coverage are less likely to undergo operative fixation for humeral shaft fractures compared to those with private insurance, even after adjusting for social and demographic variables. The observed variability underscores the necessity for more refined treatment guidelines for humeral shaft fractures. Surgeons should be aware of these potential biases affecting management decisions.
