Study: MA beneficiaries’ hospital stays longer than those under Traditional Medicare

A JAMA internal medicine study published Sept. 8 found that since the COVID-19 pandemic, Medicare Advantage beneficiaries have been experiencing longer hospital stays than those under Traditional Medicare. The study examined more than 89 million hospitalizations from 2017 to 2023 and found the average length of stay for MA admissions during that period increased from 6 to 7.1 days, while Traditional Medicare admissions grew from 5.8 to 6.3 days. The researchers noted that these trends “may reflect insurance-related discharge barriers” and that the results “are consistent with hospital industry reports.” They point to prior authorization or limited post-acute care networks as possible causes.
