KOLOA, Hawaii – Among the 2018 plans for the American Joint Replacement Registry is to increase the breadth of data collection to include more physicians, procedures, hospitals and ambulatory surgery centers, said a presenter at Orthopedics Today Hawaii 2018.

“The thing that is going to revolutionize this effort is in 2018 is we are getting the ResDAC data from CMS – the claims data. We are going to be able to take those 1 million patients, half of which are Medicare [patients], and do survivorship curves. It is going to take us to the next level,” David G. Lewallen, MD, said, here.

The American Joint Replacement Registry (AJRR) is a multicenter independent, not-for-profit organization that was incorporated in 2009. Lewallen said its goal is to improve arthroplasty care and to capture data on more than 90% of all total joint replacement procedures in the United States.

As of May 2017, enrollment in the AJRR was more than 1 million procedures and nearly 1,000 hospitals, he said. The AJRR was formally acquired by the American Academy of Orthopaedic Surgeons in August 2017 as part of the AAOS strategy to expand registries to all subspecialties and to promote family of registries.

Lewallen said that in the fourth annual report, which was released November 2017, there were more than 860,000 procedures through 2016. The per surgeon mean for primary and revision hip arthroplasty among participating surgeons was 32.2 and 5.4, respectively. The per surgeon mean for primary and revision knee arthroplasty was 45.8 and 4.9, respectively. – by Kristine Houck, MA, ELS
