For e-prescribing adopters, error rates decreased nearly sevenfold, from 42.5 per 100 prescriptions at baseline to 6.6 per 100 prescriptions one year after adoption.
For non-adopters, error rates remained high at 37 per 100 prescriptions at baseline and 38 per 100 prescriptions at one year.
Illegibility errors were very high at baseline, and not surprisingly, were completely eliminated by e-prescribing (87.6 per 100 prescriptions at baseline for e-prescribing adopters, 0 at one year).
Prescribing errors may occur much more frequently in community-based practices than previously reported. This study findings suggest that stand-alone e-prescribing with clinical decision support may significantly improve ambulatory medication safety.
