Abstract

In order to control the unsustainable rise in healthcare costs the Federal Government is experimenting with the bundled payment model for total joint arthroplasty (TJA). In this risk sharing model, providers are given one payment, which covers the costs of the TJA, as well as any additional medical costs related to the procedure for up to 90. days. The amount and severity of comorbid conditions strongly influence readmission rates and costs of readmissions in TJA patients. We identified 2026 TJA patients from our database with APR-DRG SOI data for use in this study. Both the costs of readmission and the readmission rate tended to increase as severity of illness increased. The readmission burden also increased as SOI increased, but increased most markedly in the extreme SOI patients.
