Hospitals that treat lower-income patients are more likely to have high readmission rates--more than initially thought, reports Kaiser Health News. Last year, the Centers for Medicare & Medicaid Services (CMS) in a study found that poor patients had "slightly higher readmission rates" for heart failure. Adding to the research, hospitals that had the largest share of poor patients were 2.7 times as likely to have high readmission rates, Kaiser Health News found. The news outlet looked at Medicare patients with congestive heart failure, the most common reason for readmissions, and the population mix of more than 3,000 hospitals. The analysis indicated that Medicare ranked 11.7 percent of the "most poor patient" hospitals as having worse readmission rates than the national average, while only 4.3 percent of the rest of the hospitals had worse-than-average readmission rates.
