Introduction/Purpose:
There is a paucity of literature regarding the effect of socioeconomic disparity on patient access to health care following surgery for acute musculoskeletal injuries. We hypothesized that lower socioeconomic status (SES) is independently associated with increased utilization of the emergency department (ED) for care, and less reliable outpatient follow up after ankle fracture surgery.
Methods:
A retrospective analysis was performed of 1,571 patients who underwent ankle fracture surgery between 2010 and 2020 at three large academic medical centers and one community hospital. Using 2010 United States Census data linked to place of residence, a summary measure of SES was created for each zip code. SES was divided into three percentile groups: 0-25%, 26-75% and 76-100%, wherein the 0- 25% group represented the lowest SES score. Independent patient and injury factors associated with ED visits and outpatient in-office follow up within 90 days of ankle fracture surgery were examined using multivariable Poisson regression models.
Results:
Patients in the lowest quintile of SES had a higher incidence of ED visits within 90 days after surgery (adjusted incidence ratio [aIR], 1.54, p< 0.001). Patients in the highest quintile of SES had a higher frequency of outpatient follow up within 90 days after surgery (aIR, 1.23, p< 0.001) compared to those in the middle SES quintile. Independent factors associated with increased ED visits following ankle fracture surgery were lower SES, lateral malleolus fracture, heightened comorbidities, increased BMI, Spanish-speaking patients, and patients with drug and/or alcohol dependence.
Conclusion:
Patients of lower socioeconomic status, those with substance use disorders, and those who must overcome language barriers to seek care demonstrate higher emergency resource utilization and are less likely to follow up in clinic after ankle fracture surgery. A better understanding of patient and injury factors associated with such increased ED visits may provide guidance as to which patient subpopulations may require more attention after ankle fracture surgery.
