Table 3:

Utilization of C. difficile Testing Restrictions and Hospital Characteristics Relative to Hospital C. difficile Testing Strategy

Hospital Characteristic	Toxin Testing*	NAAT Alone#	P
Restrict C. difficile testing to unformed stools	53/56 (95%)	88/95 (93%)	0.63
Age-based C. difficile testing restrictions	28/56 (50%)	47/93 (51%)	0.95
University hospital	37/60 (62%)	62/99 (63%)	0.90
Freestanding children’s hospital	35/60 (58%)	53/99 (54%)	0.56
Fewer than 350 hospital beds	39/60 (65%)	64/99 (65%)	0.97

^*Toxin Testing: Toxin test used either as a single test or part of a multi-step algorithm

^#NAAT Alone: Used either an NAAT assay that only detects C. difficile, or a multiplex PCR panel that includes C. difficile, without initial or confirmatory toxin testing
