During the 4 years after implementation of the 2-step Clostridioides difficile infection (CDI) testing algorithm, 70% to 78% of patients with suspected CDI and a positive nucleic acid amplification test but a negative toxin test (NAAT+/TOX−) received CDI treatment. Overall, 73% of NAAT+/TOX− patients were classified as having probable or possible CDI.

The topical antiseptic povidone-iodine significantly reduces skin colonization when compared with unprepared skin (p < .001). The vapocoolant 1,1,1,3,3 pentafluoropropane and 1,1,1,2-tetrafluoroethane is sprayed on skin prepared with povidone-iodine; there is no statistically significant increase in bacterial colonization.

In a survey of hospitals and of patients with Clostridioides difficile infection (CDI), we found that most facilities had educational materials or protocols for education of CDI patients. However, approximately half of CDI patients did not recall receiving education during their admission, and knowledge deficits regarding CDI prevention were common.
