Central-Line-Associated Bloodstream Infection Rates in Magnet and Non-Magnet Hospitals Before and After Matching Using Propensity Scores

	All Hospitals (N =1,995)		All Non-Magnet Hospitals (n =1,704)		All Magnet Hospitals (n = 291)		Matched Non-Magnet Hospitals (n =291)		Before Matching	After Matching
CLABSI Rate	n	%	n	%	n	%	n	%	p-value	p-value
Better	581	29.1	428	25.1	153	52.6	121	41.6	<0.001	0.008
Worse	1414	70.9	1276	74.9	138	47.4	170	58.4

Note. CLABSI, central line-associated bloodstream infection; Better, “better” than the national average; Worse, either “no different” or “worse” than the national average. p-values for differences between Magnet and non-Magnet hospitals were calculated using chi-square tests.
