Abstract
Title: Racial and Ethnic Disparities in Health Care: An Examination of State Inpatient Databases in the Utilization of and Outcomes following Total Knee Arthroplasty
Background: The U.S. population is becoming more racially and ethnically diverse yet disparities in health care still exist. One area of medical care in which racial disparities have been identified is total knee arthroplasty (TKA)¬—an efficacious and cost-effective treatment option for individuals with advanced arthritis of the knee. Previous studies have documented that racial and ethnic minorities tend to have higher rates of adverse health outcomes and face more barriers utilizing the procedure. However, these studies predominantly focused on black and white disparities and were limited to Medicare patients or veterans. In this study, we sought to study racial disparities in TKA utilization and associated health outcomes using nationally representative data.
Methods: We analyzed administrative data collected for the Hospital Cost and Utilization Project State Inpatient Databases (SID) from eight racially diverse states between 2001 and 2008. Patient race was categorized according to the SID: whites, blacks, Hispanics, Asians, Native Americans and mixed-race. Both crude and adjusted racial/ethnic disparities were evaluated. We also analyzed time trends in TKA utilization by race to assess whether access to TKA improved over time.
Results:We identified a total of 547,380 admissions between 2001 and 2008 during which a TKA procedure was performed. In comparison with whites (4.65 per 1,000 population per year), blacks (3.90), Hispanics (3.71), Asians (3.89), Native Americans (4.40) and mixed-race (3.69) had lower rates of TKA utilization (P
Conclusion: Minorities had lower rates of TKA utilization but higher rates of adverse health outcomes associated with the procedure, even after adjusting for patient and health care system related characteristics. Future studies that consider specific patient-level information with psychosocial and behavioral factors are needed.
