Health Policy and EconomicsCost Analysis of Total Joint Arthroplasty Readmissions in a Bundled Payment Care Improvement Initiative
Section snippets
Methods
From January 2013 to December 2013, all Medicare patients undergoing either primary THA or TKA at our institution were enrolled in the BPCI Initiative. The BPCI Initiative agreement included all patients assigned to Medical Severity–Diagnosis-Related Groups: 469 and 470 patients undergoing primary THA or TKA. CMS followed all patients enrolled in the BPCI Initiative throughout the 90-day period after surgery. This included TKA, THA, partial hip arthroplasty, and partial or total hip resurfacing
Results
A total of 664 Medicare patients received either a THA or TKA and were enrolled in the BPCI Initiative (357 THAs, 307 TKAs) in 2013. Eighty readmissions in 69 of the 664 patients (10%) occurred within 90 days. Fifty-three readmissions (45 patients) were identified after THA (66% of all readmissions, ages 49-91, 18 males, and 28 females). The overall readmission rate after THA was 13%. Twenty-seven readmissions (24 patients) were identified after TKA (34% of all readmissions, ages 47-83, 7
Discussion
In this report, we identified the cost burden of readmissions after primary THA and TKA in a model 2 bundled payment agreement. CMS tracks and reports all readmissions of patients participating in the BPCI Initiative occurring within the United States. This enables participating institutions, such as ours, to know with certainty the CMS reimbursement and number of readmissions of their arthroplasty patients regardless of where the readmission occurs. The orthopedic literature is currently
