Data Elements We Collect
We have the capability of collecting several different types of data in our three file layouts. Certain data elements and specific measures may be required by either the Registry Program or CMS to qualify for some quality initiatives. Below is a list of the data elements in each file layout with links to more detailed information. AJRR’s data elements can also be viewed in one place here and the Shoulder & Elbow Registry’s (SER) data elements can be viewed in one place here.

The AAOS Registry Program believes that we are improving orthopaedic care through data. Not only is it our mission, but our staff lives this through the daily interactions with the people who work at the hospitals, surgery centers, and private practice groups who give us their data. 










Our Annual Audit Confirms Data Integrity
AAOS Registries are built on technology that allows your site to access all your AAOS orthopaedic registries in one place. RegistryInsights® subscribers currently have access to three dashboards: Data Submitters Dashboards, Institution Dashboards, and Surgeon Dashboards.
