Sensitivity Analyses Assessing Odds of Hospital-Onset C. difficile Infection (HO-CDI) While Varying the Length of Time We Considered the Bed to be Contaminated for After Prior Occupant Tested Positive for C. difficile

Variable	60 Days Adjusted OR a (95%CI)	30 Days Adjusted OR a (95% CI)	14 Days Adjusted OR a (95% CI)	7 Days Adjusted OR a (95% CI)
Exposure to contaminated bed	1.3 (1.0–1.8)	1.6 (1.1–2.2)	1.6 (1.0–2.4)	1.5 (0.9–2.7)

Note. OR, odds ratio; CI, confidence interval; ICU, intensive care unit.

^a Adjusted for ICU admission and time at risk prior to HO-CDI or discharge, whichever occurred first.
