Purpose:
To assess independent predictors of surgery after an emergency department visit for shoulder instability, including patient-related and socioeconomic factors.
Methods:
Patients presenting to the emergency department were identified in the New York Statewide Planning and Research Cooperative System database from 2015 to 2018 by International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis codes for anterior shoulder dislocation or subluxation. All shoulder stabilization procedures in the outpatient setting were identified using Current Procedural Terminology codes (23455, 23460, 23462, 23466, and 29806). A multivariable logistic regression was performed to assess the impact of patient factors on the likelihood of receiving surgery. The variables included in the analysis were age, sex, race, social deprivation, Charlson Comorbidity Index, recurrent dislocation, and primary insurance type.
Results:
In total, 16,721 patients with a shoulder instability diagnosis were included in the analysis and 1,028 (6.1%) went on to have surgery. Patients <18 years old (odds ratio [OR] 8.607, P < .0001), those with recurrent dislocations (OR 2.606, P < .0001), or worker's compensation relative to private insurance (OR 1.318, P = .0492) had increased odds of receiving surgery. Hispanic (OR 0.711, P = .003) and African American (OR 0.63, P < .0001) patients had decreased odds of surgery compared with White patients. Patients with Medicaid (OR 0.582, P < .0001) or self-pay (OR 0.352, P < .0001) insurance had decreased odds of undergoing surgery relative to privately insured patients. Patients with greater levels of social deprivation (OR 0.993, P < .0001) also were associated with decreased odds of surgery.
Conclusions:
Anterior glenohumeral instability and subsequent stabilization surgery is associated with disparities among patient race, primary insurance, and social deprivation.
Clinical Relevance:
Considering the relationship between differential care and health disparities, it is critical to define and increase physician awareness of these disparities to help ensure equitable care.
