Patterns and costs of 90-day readmission for surgical and medical complications following total hip and knee arthroplasty.
Unplanned readmissions following elective total hip (THA) and knee (TKA) arthroplasty as a result of surgical complications likely have different quality improvement targets and cost implications than those for nonsurgical readmissions. In this study, the investigators compared payments, timing, and location of unplanned readmissions with Center for Medicare and Medicaid Services (CMS)-defined surgical complications to readmissions without such complications.

Variation in Medicare expenditures for treating perioperative complications: the cost of rescue.
The researchers evaluated differences across hospitals in the costs of care for patients surviving perioperative complications after major inpatient surgery. After 4 selected inpatient operations, substantial variation was observed across hospitals regarding Medicare episode payments for patients rescued from perioperative complications. Notably, higher Medicare payments were not associated with improved clinical performance.

Medicare claims can be used to identify US hospitals with higher rates of surgical site infection following vascular surgery.
This study found that among Medicare patients who underwent vascular surgery at 2,512 U.S. hospitals, a patient undergoing surgery in a hospital ranked in the worst-performing decile based on claims had a 2.5 times greater likelihood of developing a chart-confirmed surgical site infection relative to a patient characteristics in a hospital in the best-performing decile.
