Feldstein AC, Smith DH, Perrin N, et al. Reducing warfarin medication interactions: an interrupted time series evaluation. Arch Intern Med. 2006;166(9):1009-15.
The authors evaluated the effectiveness of computerized alerts in reducing co-prescribing of warfarin and interacting medications. They found that the alerts had a modest impact on minimizing this potentially dangerous behavior.
