Published results showed African American patients were more likely to be referred to inpatient rehabilitation facilities or skilled nursing facilities for postoperative care and rehabilitation after elective total knee arthroplasty compared with white patients.

Using data from the Pennsylvania Health Care Cost Containment Council Database, researchers measured discharge disposition and 90-day hospital readmission among patients who identified as either African American or white and who underwent primary TKA in 170 non-governmental acute care hospitals from April 2012 to September 2015.

Among 107,768 patients, results showed 6.8% were African American, 63.4% were women, 43.1% were younger than 65 years and 56.3% were insured by Medicare. Discharge to an inpatient rehabilitation facility or a skilled nursing facility rather than home health care or home self-care was more common among African American patients vs. white patients younger than 65 years of age, according to results of the multivariable logistic regression analysis. Researchers also found African American patients younger than 65 years of age had greater odds of 90-day hospital readmission. Results showed African American patients 65 years of age or older were more likely to be discharged to a skilled nursing facility compared with white patients. Researchers noted an association between discharge to an inpatient rehabilitation facility with greater odds of 90-day readmission in both age groups.

“Future studies are needed to evaluate the decision-making process regarding discharge destination for post-acute care and rehabilitation after elective TKA and how social determinants of health, such as patient race/ethnicity, affect these decisions,” the authors wrote. “Future studies should also examine how changing Centers for Medicare & Medicaid Services policy reforms, such as Bundled Payment for Care Improvement, affect not only cost and quality of care but also equity.” – by Casey Tingle
