Although antibiotic prophylaxis was common among both cases and controls (84% and 89%), more than one-half of cases (53%) were given prophylaxis outside the recommended window or were exposed for more than 24 h in comparison to 29% of controls. Patients who received untimely (OR=3.13, 95% confidence interval [CI] 1.5-6.4) and discontinued inappropriately (OR 6.38, 95% CI=2.5-16.2) prophylaxis were more likely to develop an ESBL SSI. In addition, patients with an organ\/space infection compared with superficial had a higher rate of a resistant infection (OR 4.2, 95% CI 1.3-13.9).
