		Proportion of Supplemental/Float Nurses
Hospital Characteristics	All (n = 198)	<5% n = 61	5%–15% n = 109	>15% n = 28	P value
Teaching hospitals, %	37.5	32.0	39.6	40.0	.637
Hospital size, %
Small (≤100 beds)	23.3	22.0	20.8	36.0	.194
Medium (101–250 beds)	56.3	64.0	53.5	52.0
Large (>250 beds)	20.4	14.0	25.7	12.0
High-technology hospitals, %	29.0	22.0	33.7	24.0	.278
