Logistic regression of variables predictive of delirium being recognised

	Beta	SE	Wald	Freedom	OR	CI		P value
						Lower	Upper
Screening	1.62	0.43	14.43	1	5.05	2.19	11.65	<0.001*
Grade of screener			1.60	3				0.659
Age	−0.03	0.03	1.03	1	0.97	0.92	1.03	0.309
Gender	0.53	0.41	1.65	1	1.70	0.76	3.80	0.199
Dementia	0.19	0.48	0.15	1	1.20	0.47	3.09	0.700
Frailty			1.348	2				0.510
Specialty			7.00	6				0.324

Screening for delirium was associated with nearly five-fold increased likelihood of delirium recognition. The grade or profession of the screener did not impact on the chances of delirium being recognised. Recognition was not affected by age, gender, dementia, frailty or specialty.
