Consumers here at first did not believe the health insurance premiums they saw when they went shopping for coverage this month on HealthCare.gov. Only five plans were available, and for a family of four with parents in their mid-30s, the cheapest plan went typically for more than $2,400 a month, nearly $30,000 a year.

With the deadline for a decision less than a month away, consumers are desperately weighing their options, dismayed at the choices they have under the Affordable Care Act and convinced that political forces in Washington are toying with their health and well-being.

Former President Barack Obama and his advisers claimed that their 2010 health insurance law would create incentives to provide better and more efficient patient care. A new study suggests that one of their bright ideas has since gone disastrously wrong.

This week the Journal reports:

The Affordable Care Act required Medicare to penalize hospitals with high numbers of heart failure patients who returned for treatment shortly after discharge. New research shows that penalty was associated with fewer readmissions, but also higher rates of death among that patient group.

The researchers said the study results, being published in JAMA Cardiology, can’t show cause and effect, but “support the possibility that the [penalty] has had the unintended consequence of increased mortality in patients hospitalized with heart failure.”
