Relation of Reported Sedation and Ventilator Weaning Practices to Ventilator Time in Norwegian Intensive Care Units

Table 5

Effect of reporting use of sedation guidelines, weaning protocols, and delirium evaluations on ventilator time and length of ICU stay.

	“How often are the guidelines or protocols used?”	Number of stays	Mean time on ventilator, days (median)	Mean difference in days with corresponding 95% confidence intervals	Mean length of ICU stay, days (median)	Mean difference in days with corresponding 95% confidence intervals
Sedation guidelines	“Rarely” or “Sometimes”	600	7.0 (4.0)	0.7	10.0 (6.6)	0.6
	“Often” or “As a rule”	1,929	7.7 (4.5)	95% CI = 0.1–1.4,	9.4 (6.2)	95% CI = 0.4–1.4,
Weaning protocols	“Rarely” or “Sometimes”	1,072	6.9 (3.5)	0.8	10.5 (6.8)	1.1
	“Often” or “As a rule”	1,935	7.7 (4.8)	95% CI = 0.2–1.4,	9.4 (6.2)	95% CI = 0.3–1.8,
Evaluation of delirium	“Rarely” or “Sometimes”	3,652	7.3 (4.3)	1.1	9.9 (6.5)	2.5
	“Often” or “As a rule”	1,565	6.2 (3.4)	95% CI = 0.6–1.6,	7.4 (4.4)	95% CI = 2.0–3.0,

Stays resulting in death in the ICU, transfer, or ventilator time <24 hours were excluded.
