Socioeconomically Disadvantaged CMS Beneficiaries Do Not Benefit From the Readmission Reduction Initiatives

摘要

We assessed the impact of minority and socioeconomic status on 30-day readmission rates after 3825 primary total hip arthroplasty (THA) and 3118 primary total knee arthroplasty (TKA) procedures. Minority patients had higher THA (7.4% vs 3.2%, P= 0.001) and TKA (5.4% vs 3.7%, P < 0.001) readmission rates. Low socioeconomic status was associated with higher THA (6.0% vs 3.1%, P < 0.001) and TKA (6.3% vs 3.8%, P = 0.02) readmission rates. Risk reduction initiatives were effective after TKA, but minority status and low socioeconomic status were still associated with higher 30-day readmission rates (4.6% vs 1.8%, P < 0.01). Focused postoperative engagement for Centers for Medicare and Medicaid Services (CMS) beneficiaries less than 65 years of age may help reduce complications and 30-day readmissions.
