Total knee arthroplasties (TKAs) are common surgical procedures for addressing knee pain and functional impairment, primarily caused by osteoarthritis. From 2008 to 2010, TKAs were the most common procedure for adults age 45 and older. From 2000 to 2010, physicians performed 5.2 million TKAs, with 693,400 procedures performed in 2010 alone (Williams, Wolford, & Bercovitz, 2015). Although TKAs were introduced as a procedure for older adults, the mean age of patients undergoing TKA is decreasing. In 2010, the mean age for those undergoing TKA was 66.2, a 3.9 percent decrease from 68.9 in 2000. Kurtz et al. (2009) projected that patients younger than 65 would account for 55 percent of TKAs by 2030. This growth in knee surgeries for younger patients is significant because they often require more expensive joint arthroplasties that will better withstand wear caused by physical activity (Bozic et al., 2006). 

This measure evaluates whether patients complete a patient-reported functional status assessment (FSA) before and after a TKA. Measuring functional status for patients undergoing total knee replacement permits longitudinal assessment - from the patient's perspective - of the impact of surgical intervention on pain, physical function, as well as health-related quality of life (Rothrock et al., 2010).

While there is no clinical guideline recommending that clinicians assess patients who are undergoing total knee replacements using patient-reported outcomes of function and pain, several clinical specialty societies support the use of a general health questionnaire and a disease-specific questionnaire for these patients. In particular, they recommend the Veterans RAND 12-item health survey (VR-12) or the Patient-Reported Outcomes Measurement Information System [PROMIS]-10-Global as the general health questionnaire and the Knee Injury and Osteoarthritis Outcome Score [KOOS], Jr. as the disease-specific questionnaire (American Association of Orthopaedic Surgeons, the American Joint Replacement Registry, The Hip Society, The Knee Society, & the American Association of Hip and Knee Surgeons, 2015).

The same functional status assessment (FSA) instrument must be used for the initial and follow-up assessment.

This eCQM is a patient-based measure.

This version of the eCQM uses QDM version 5.6. Please refer to the eCQI resource center (https://ecqi.healthit.gov/qdm) for more information on the QDM.

TBD

Patients 19 years of age and older who had a primary total knee arthroplasty (TKA) in the year prior to the measurement period and who had an outpatient encounter during the measurement period

Equals Initial Population

Exclude patients with two or more fractures indicating trauma in the 24 hours before or at the start of the total knee arthroplasty or patients with severe cognitive impairment that starts before or in any part of the measurement period.

Exclude patients who are in hospice care for any part of the measurement period.

Patients with patient-reported functional status assessment results (i.e., Veterans RAND 12-item health survey [VR-12], Patient-Reported Outcomes Measurement Information System [PROMIS]-10 Global Health, Knee Injury and Osteoarthritis Outcome Score [KOOS], KOOS Jr.) in the 90 days prior to or on the day of the primary TKA procedure, and in the 270 - 365 days after the TKA procedure
