Columbia Aging Center epidemiologist co-authors new report from National Academies on using race and ethnicity in biomedical research

The National Academies report outlines nine actionable recommendations to advance the responsible use of race and ethnicity in biomedical research, including community engagement and data inclusivity. The report aims to provide a key guide for researchers considering using race and ethnicity throughout their research process.

Most Medicare beneficiaries do not compare prescription drug plans – and may be sticking with bad plans

A USC Schaeffer study found that over half of Medicare beneficiaries with stand-alone Part D plans did not switch due to lack of plan comparisons, with many unaware of how to change plans or missing out on better coverage options. This complacency allows insurers to exploit beneficiaries' inattention and boost profits.
