Ambulatory computerized prescribing and preventable adverse drug events.

Computerized provider order entry (CPOE) systems have been shown to prevent prescribing errors, though their effect on clinical adverse drug events (ADEs) remains controversial. A limitation of the existing evidence in this area is that most studies have been in the hospital setting. This study of electronic prescribing in primary care clinics in Boston and Indianapolis found results similar to hospital-based studies, in that the overall rate of preventable ADEs was unchanged after CPOE implementation. In many cases, physicians' failure to heed decision support warnings—possibly due to alert fatigue—may have contributed to ADEs. An interesting, although unexplained, finding in this study was that the baseline ADE rate was more than seven times higher at the Indianapolis sites compared to the Boston sites. A case of a hospital admission due to an outpatient adverse drug event is discussed in a previous AHRQ WebM&M commentary.
