Background: To study the main risk factors associated with Clostridium difficile infection in a geriatric unit.
Patients and method: Retrospective case-control study.
Results: In a multivariate analysis, tube feeding (OR = 6.73; IC 95%, 1.01-45.35) and length of antibiotic therapy (OR = 1.15; IC, 95% 1.01-1.28) were independent variables which associated with C. difficile infection.
Conclusions: Antibiotic treatment, tube feeding and fragility are associated with C. difficile infection.
