Adverse Drug Events (Drug Errors)

What is an adverse drug event?

An adverse drug event (ADE), or drug error, is an injury resulting from the use of any drug.

Why do we measure?

  • Adverse drug events can have a negative effect on a patient’s recovery

  • Improving is part of providing a safe healing environment

  • We continue to strive to reduce the number of ADEs to zero

How do we measure?

  • Employee reporting of ADEs is voluntary

  • We track medications that are used only to revese side effects of other medications

  • All ADEs are placed on a nine-point clinical severity scale depending on the seriousness of the error

  • Rate of error is calculated by the number of ADEs per 1000 doses of medication

How are we improving?

We concentrate on providing the right medication to the right patient, at the right time. Since 2009, our error rate has continued to decline.

  • Non-harm-causing ADEs (1-3)

    • Error rate below 1.4 since 2009

    • Error rate below 1.0 in 2013

  • Short-term-causing ADEs (4-6)

    • Error rate below 0.2 since 2009

    • Error rate below 0.05 in 2013

  • Long-term-causing ADEs (7-9)

    • Error rate below 0.002 since 2009

    • Zero eroors since 2010
