End-user use of bypass function across study phases

	Immediate go-live, Phase 2	12 weeks post-go-live, Phase 2
Total number of alert forms completed	998	1101
Total number of bypasses	788	918
Alert form bypass rate (%)	79*	83*
Median number of bypasses per patient	3	3
Median number of bypasses per doctor	2 (1–22)	2 (1–20)

*P = 0.01.

Each alert form could be completed (i.e. closed out) by bypassing, recording an exclusion or recording an acknowledgment of the form (by clicking option (iii): ‘None of the above’—see the text for details).

In Phase 3, immediate alert dismissal avoided the need for subsequent interaction with the CCDS (the AKI form was completed in only 3/280 alerting patients).
