Table 3 Rate of ED presentations pre and post-implementation

	Negative binomial regressions ^a Adjusted estimates ^b
	IRR (95% CI) ^c	p-value
ED presentation during ED ACE hours	0.71 (0.46, 1.1)	0.122
All ED presentations (ED ACE + non-ED ACE hours)	0.96 (0.65, 1.41)	0.844
	Logistic regression ^d Adjusted estimates ^e
	OR (95% CI) ^f	p-value
ED presentation during ED ACE hours	0.31 [0.11, 0.87]	0.025

^aNegative binomial regressions are based on episodes of care resulting in an ED presentation (n = 333 pre-implementation, n = 421 post-implementation)
^bEstimates from negative binomial regressions, adjusted for study month and implementation status
^cRate per 100 RACF beds
^dLogistic regressions are based on all episodes of care within ED ACE hours, whether it resulted in an ED presentation or not (n = 333 pre-implementation, n = 421 post-implementation)
^eEstimates from a logistic regression, adjusted for study month and implementation status
^fOdds ratio of an episode of care resulting in an ED presentation post relative to pre implementation
