  • *Scoring on a scale from 0 to 10 where 0 is no effect and 10 is death.

  • †Severity was assigned using the National Coordinating Council for Medication Error Reporting and Prevention index. All preventable ADEs were assigned class E (temporary harm that required intervention) except five cases assigned to class G because it was not possible to exclude permanent harm.

  • ADE, adverse drug event; BCMA, bar code-assisted medication administration.
