Socioeconomic Factors Influencing Self-reported Outcomes After Posterior Wall Fractures of the Acetabulum: Lessons Learned From a Hispanic Population.

INTRODUCTION

Demographic and socioeconomic factors are important determinants that may affect patient self-reported outcomes after acetabular fracture surgery. Hispanics, as a minority group, have an increased tendency to suffer demographic and socioeconomic disparities. At the present time, there is scant information regarding their role among Hispanic patients with acetabular fractures. The aim of this study was to investigate whether demographic or socioeconomic factors would affect satisfaction and self-reported functional outcomes in Hispanic patients who endured open reduction and internal fixation (ORIF) of posterior wall fractures of the acetabulum.

METHODS

A cross-sectional study of 78 patients with posterior wall fracture of the acetabulum treated with ORIF from 2011 to 2017 was performed. Data from demographics (age, sex, and body mass index [BMI]) and socioeconomic factors (household income, highest educational level achieved, employment status, type of medical insurance, workers' compensation involvement, and injury-related litigation process) were obtained and compared with the Short Musculoskeletal Form Assessment-46 (SMFA-46) questionnaire using a multivariable logistic regression analysis.

RESULTS

Unemployment was the most significant variable associated with dissatisfaction among 15 of the 46 responses of the SMFA-46 (P < 0.048). Patients who had an overweight or obese BMI and had an age of 41 years or older exhibited significantly worse outcomes in 7 of the 46 questions (P < 0.049). Finally, women were less likely to be satisfied in 1 of the 46 questions (P = 0.028). No notable difference was observed in any of the SMFA-46 responses regarding insurance plan, educational level, workers' compensation involvement, and injury-related litigation process.

DISCUSSION

A strong association exists between dissatisfaction after ORIF of posterior wall fractures of the acetabulum and employment status, BMI, and age among the Hispanic population. Addressing socioeconomic factors can be critical to overcome dissatisfaction and improve functional status among Hispanic patients with acetabular fractures.
