A medication reconciliation program may help reduce hospital emergency room readmissions by as much as 6%, a recent study shows.

A British research team compared outcome measures between two groups of hospital patients: one that received medication reconciliation upon admission and discharge, and one group that received “usual care.”

The reconciliation group had a readmission rate of 17.9%, compared to 26.7% in the control group. That translates into a 6% reduction in three-month readmission rates, researchers said.

Results were published in March in the journal  Health Services Research
