Overview

THA/TKA Complication Measure

The Centers for Medicare & Medicaid Services’ (CMS’s) publicly reported risk-standardized complication measure for elective primary total hip arthroplasty (THA) and/or total knee arthroplasty (TKA) assesses a broad set of healthcare activities that affect patients' well-being. The outcome for this measure captures eight different complications, each within a specific and clinically meaningful time period, during which the outcome can be attributed to the hospital that performed the procedure. Measuring and reporting risk-standardized complication rates will inform health care providers of opportunities to improve care, strengthen incentives for quality improvement, and provide consumers information to help them choose a hospital at which to have an elective surgical procedure.

The public reporting of the risk-standardized complication measure is consistent with the priorities of the Department of Health and Human Services' National Quality Strategy, which aims to: a) improve health care quality; b) improve the health of the U.S. population; and c) reduce the costs of health care. Public reporting of the CMS THA/TKA complication measure fulfills federal mandates in the Deficit Reduction Act (DRA) of 2005 requiring the Secretary of Health and Human Services to make outcome and efficiency measures publicly available under the Hospital Inpatient Quality Reporting (IQR) Program.

In 2013, CMS began to publicly report on Hospital Compare the performance of hospitals on the risk-standardized THA/TKA complication measure as part of the IQR program.
