Hemiarthroplasty or Total Hip Arthroplasty: Is There a Racial Bias in Treatment Selection for Femoral Neck Fractures?

abstract
INTRODUCTION: Hip fractures in the elderly individuals are associated with significant morbidity and mortality, and outcomes are directly related to prompt surgical intervention with either total hip arthroplasty (THA) or hemiarthroplasty. Minority hip fracture patients have increased delays to surgical intervention and poorer functional outcomes. This study explored racial biases in the surgical treatment decision between THA and hemiarthroplasty for displaced femoral neck fractures as well as racial disparities in postoperative complications, readmission rates, and 30-day mortality. METHODS: We retrospectively reviewed the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) from 2006 to 2014. Patients were identified using diagnosis code for transcervical femoral neck fractures and Current Procedural Terminology codes for THA or hemiarthroplasty. A multivariable regression analysis was conducted including race, demographic information, and medical comorbidities. RESULTS: Of 11 408 patients, race was recorded in 8538 individuals. Most patients were white (88.3%), followed by Hispanic (4.7%), African American (4.1%), and Asian/Native Hawaiian/Pacific Islander/American Indian/Alaska Native (2.9%). No differences were observed in the likelihood of receiving a THA versus hemiarthroplasty among racial groups. Only younger age and steroid use were independent risk factors for receiving a THA. Race was significantly associated with postoperative mortality (P = .014) and major postoperative complications for the Asian cohort (P = .013). DISCUSSION: The NSQIP data do not support a racial bias in the selection of patients for THA versus hemiarthroplasty. However, this study found racial disparities in postoperative mortality and complications. The reasons underlying the differences in postoperative outcomes are uncertain but may be the result of specific challenges to accessing care. CONCLUSION: There was no racial bias in the treatment of femoral neck fractures. However, there were racial disparities in postoperative mortality and complication rates. Further research is warranted to elucidate the true causes of these observed disparities.
