Burnett RA, Serino J, Yang JW, et al. - This study was undertaken to ascertain if advancements in perioperative care led to a reduction in post-acute care costs and resource utilization following total knee arthroplasty (TKA). Researchers examined a consecutive series of 79,843 primary TKA patients from the Humana claims dataset from 2007-2016. They compared demographics, episode-of-care, and post-acute care costs, readmissions, and discharge disposition. Controlling for demographics and comorbidities, they conducted multivariate regression analyses to compare trends in discharge disposition and post-acute care costs. The results demonstrated that there has been 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.
