The authors of the study examined 30-day hospital readmission for individuals over the age of 65 for six major surgeries – isolated coronary artery bypass graft, pulmonary lobectomy, endovascular repair of abdominal aortic aneurysm, open repair and abdominal aortic aneurysm, colectomy, and hip replacement.
They found that Black patients on traditional Medicare where 33 percent more likely to be readmitted after a surgery than Whites. More strikingly, Black patients enrolled in Medicare Advantage plans were 64 percent more likely to be readmitted than Whites.
Dr. Li notes that “our findings suggest that the risk-reduction strategies adopted by Medicare Advantage plans have not succeeded in lowering the markedly higher rates of readmission for Black patients compared to White patients.”
The authors speculate that several factors may be behind this disparity, such as lower quality surgical care, poorer support and follow-up care when a patient leaves the hospital, and less social and community support.
