Burnett RA, Serino J, Yang J, et al. - This study was sought to ascertain whether advancements in perioperative care led to a reduction in post-acute care costs and resource utilization following total knee arthroplasty (TKA). Between 2007 to 2016, researchers examined a consecutive series of 79,843 primary TKA patients from the Humana claims dataset. They compared demographics, episode-of-care and post-acute care costs, readmissions, and discharge disposition. The average episode-of-care costs ($46,754 vs $31,856) and post-acute care costs per patient decreased ($20,224 vs $13,498) between 2007 and 2016. The results demonstrated a substantial decline in post-acute care costs and resource utilization following TKA, with the largest decrease occurring following the introduction of Medicare bundled payment models in 2013.
