MRSA colonization at hospital admission was associated with recent prior hospitalization (odds ratio [OR], 2.4 [95% confidence interval (CI), 1.3–4.7]; P < .01), nursing home exposure (OR, 3.8 [95% CI, 2.3–6.3]; P < .01), and history of exposure to healthcare-associated pathogens (MRSA carriage: OR, 8.0 [95%CI, 4.2–15.1]; Clostridium difficile infection: OR, 3.4 [95% CI, 2.2–5.3]; vancomycin-resistant Enterococci carriage: OR, 3.1 [95% CI, 2.5–4.0]; P < .01 for all) (McKinnell et al., 2014, p. 1077). Select comorbidities were associated with MRSA colonization (congestive heart failure, diabetes, pulmonary disease, immunosuppression, and renal failure; P < .01 for all), while others were not (human immunodeficiency virus, cirrhosis, and malignancy). ICU admission was not associated with an increased risk of MRSA colonization (OR, 1.1 [95% CI, 0.6–1.8]; P = .87) (McKinnell et al., 2014, p.…
