Associations between hospital process-structure factors and reported delivery of high-level activity to patients on mechanical ventilation

	High-Level Activity Hospitals (n = 22)	OR	95% CI	P Value
Hospital volume >20,000 patient-days/yr, n (%)	16 (72.7)	5.33	1.54–18.48	0.008
ICU volume >5,000 patient-days/yr, n (%)	15 (68.2)	5.20	1.51–17.93	0.008
Part of a larger hospital network, n (%)	13 (59.1)	2.57	0.80–8.21	0.11
Academic ICU, n (%)	11 (52.4)	4.40	1.23–15.63	0.02
Intensivist-led ICU, n (%)	4 (18.2)	1.17	0.28–4.94	0.84
Advanced care providers in ICU, n (%)	17 (77.3)	4.33	1.24–14.93	0.02
Computerized order entry, n (%)	17 (77.3)	1.32	0.37–4.75	0.68
Written protocol for ICU activity, n (%)	14 (63.6)	5.54	1.60–19.18	0.006
