Consider 2 patients. Patient A, a man aged 70 years, is a Medicare beneficiary with hypertension, diabetes, and congestive heart failure. He is an affluent retiree with a doctoral degree; he lives with his wife, plays golf, drives to appointments to see his primary care physician (of 10 years), and has ample coverage for prescription drugs. Patient B, a man aged 70 years, is also a Medicare beneficiary with hypertension, diabetes, and congestive heart failure. However, patient B is of modest means; he did not complete high school, lives alone in urban housing, speaks limited English, relies on his working children to make medical appointments at a clinic, and has gaps in his prescription drug coverage. If a hospital discharged both of these patients with congestive heart failure, which one would be more likely to be readmitted within 30 days?
