Smith & Nephew’s OXINIUM™ Technology for Hips could save the US Health System an estimated $296 Million in 2020

Smith & Nephew (LSE: SN, NYSE: SNN), the global medical technology business, today presented new data at the International Society for Pharmacoeconomics and Outcomes Research (ISPOR), Annual Meeting in New Orleans. This data, presented for the first time, compared 90-day episode of care outcomes for its proprietary OXINIUM™, Oxidized Zirconium alloy, bearing surface with all other non-OXINIUM bearing surfaces for total hip replacement surgery. Key takeaways included:

If OXINIUM was used in all US primary hip procedures in 2020, projected volume to be 498,0002, there could be an estimated $296 million savings to the US health system*.

The study reports on data collected using the Comprehensive Care for Joint Replacement (CJR) model developed by Centers for Medicare and Medicaid Services (CMS) to improve outcomes through a bundled payment model. Recognition by CMS of OXINIUM as a unique bearing surface has enabled this large-scale comparison of OXINIUM versus non-OXINIUM bearings for the first time.

Patients have a higher risk for postoperative complications and readmissions when discharged to a skilled nursing facility compared with patients discharged to home3.  With the increased emphasis on quality and value, readmission rates are an important indicator for quality of patient care4.

“Smith & Nephew is committed to helping patients live a Life Unlimited. This comes to fruition through innovative technologies, like the OXINIUM hip bearing surface, that lead the way in healthcare by reducing the economic burden of readmissions1 and helping patients return home sooner1,” said Mike Donoghue, Smith & Nephew Senior Vice President of Global Orthopaedics.

OXINIUM femoral heads launched in 2002 and have now been implanted over 700,000 times worldwide5.
