Reducing the Frequency ofErrors in Medicine UsingInformation Technology DAVID W. BATES, MD, MSC, MICHAEL COHEN, MS, RPH, LUCIAN L. LEAPE, MD, J. MARC OVERHAGE, MD, PHD, M. MICHAEL SHABOT, MD, THOMAS SHERIDAN, SCD A b s t r a c t Background: Increasing data suggest that error in medicine is frequent and
results in substantial harm. The recent Institute of Medicine report (LT Kohn, JM Corrigan,
MS Donaldson, eds: To Err Is Human: Building a Safer Health System. Washington, DC:
National Academy Press, 1999) described the magnitude of the problem, and the public
interest in this issue, which was already large, has grown.
Goal: The goal of this white paper is to describe how the frequency and consequences of
errors in medical care can be reduced (although in some instances they are potentiated) by
the use of information technology in the provision of care, and to make general and specific
recommendations regarding error reduction through the use of information technology.
Results: General recommendations are to implement clinical decision support judiciously;
to consider consequent actions when designing systems; to test existing systems to ensure
they actually catch errors that injure patients; to promote adoption of standards for data and
systems; to develop systems that communicate with each other; to use systems in new ways;
to measure and prevent adverse consequences; to make existing quality structures meaningful;
and to improve regulation and remove disincentives for vendors to provide clinical decision
support. Specific recommendations are to implement provider order entry systems, especially
computerized prescribing; to implement bar-coding for medications, blood, devices, and
patients; and to utilize modern electronic systems to communicate key pieces of asynchronous
data such as markedly abnormal laboratory values.
Conclusions: Appropriate increases in the use of information technology in health care—
especially the introduction of clinical decision support and better linkages in and among systems,
resulting in process simplification—could result in substantial improvement in patient safety.

As a result, it is attractive from the sample sizeperspective to track error rates, although it is impor-tant to recognize that errors vary substantially intheir likelihood of causing injury.20 Clinical Decision Support
While many errors can be detected and corrected byuse of human knowledge and inspection, these rep-resent weak error reduction strategies. In 1995, Leapeet al.13 demonstrated that almost half of all medica-tion errors were intimately linked with insufficientinformation about the patient and drug. Similarly,when people are asked to detect errors by inspection,they routinely miss many.21 It has recently been demonstrated that computerizedphysician order entry systems that incorporate clini- Alert detection system.
