Table 3

Severity of observed errors or (potential) ADEs before and after implementation of BCMA

	Outcome measure	Baseline	Post-BCMA	% Change from baseline	p Value
Poon et al¹⁰	Percentage clinically significant potential ADEs	1.8	0.9	48.5	<0.001
	Percentage serious potential ADEs	1.3	0.6	54.1	<0.001
	Percentage life-threatening potential ADEs	0.03	0.01	53.9	0.34
Franklin et al¹¹	Mean score of potential error severity*	2.7	2.5		0.39
Morris et al¹⁴	n/1000 doses of preventable ADEs†	0.86/1000 doses	0.43/1000 doses	47	0.044

*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.
