Quality Improvement Resources

The International Society of Arthroplasty Registries (ISAR) has been developing methodologies and generating reports on surgeon, hospital, and implant performance that can be used for quality improvement. These reports may serve as a resource for new and developing registries and facilitate developing common data elements and definitions across registries.

The purpose of this web page is to provide a collection of resources related to the application of arthroplasty registry data to quality improvement. The resources include reports from existing registries, registry quality improvement publications about QI methodologies and impact, and examples of registry websites that provide QI data.

This web page is intended as a living repository. Review of the included materials and submission of additional resources is requested. Interested in submitting? Please submit links, publications, and other relevant documentation to implantregistries@kp.org.
