Heart attack readmissions higher in U_S_

Rates of hospital readmission following a heart attack are much higher in the U.S. than in other countries, according to a new study. The findings suggest that a prescription to buy Plavix may benefit many individuals.

For the study, researchers from Duke University analyzed medical records for patients hospitalized for heart attacks between 2004 and 2006 in the U.S., Australia, Canada and a number of European countries. Patients in the U.S. tended to have the highest readmission rates.

The researchers said that finding a solution to this problem is critical, as it is believed that preventable readmissions add billions of dollars to hospitals' expenses, which makes care less affordable.

"Our analysis shows that readmission may be preventable because rates are nearly one-third lower in other countries, suggesting that the U.S. health care system has features that can be modified to decrease readmission rates," the team wrote in their report.

They added that understanding what accounts for international differences in readmission rates may help healthcare policymakers in the U.S address the problem.
