Emergency Department Observation versus Readmission Following Total Joint Arthroplasty: Can We Avoid the Bundle Buster?
As the Center for Medicare and Medicaid (CMS) moves toward bundled payment plans for total joint arthroplasty (TJA), it becomes necessary to reduce factors that increase cost for an episode of care such as readmissions. The goal of this study is to evaluate the payment for observation stay versus readmission for patients who present to the emergency department. (Source: The Journal of Arthroplasty)

Radiologist Overreads of Intraoperative Radiographs- Value or Waste?
All aspects of the arthroplasty pathway must be scrutinized to maximize value and eliminate unnecessary cost. Radiology providers ’ contracts with hospitals often call for readings of all radiographs. This policy has little effect on patient care when intraoperative radiographs are taken and used to make real time decisions. In order to determine the value of radiologist overreads, we asked three questions: what was the dela y between the time an intraoperative radiograph was taken and time the report was generated, were the overreads accurate, and what is the associated cost?

Steroid injections are common yet have immune-modulating effects and can alter gene expression which may delay definitive arthroplasty and further damage cartilage. Nonsteroidal anti-inflammatory injections may offer a safer profile due to their differing mechanism of action; however, there is a relative dearth of information regarding their efficacy.
