Few studies have quantitatively assessed the impact of exposure to hospital roommates on the acquisition of infections. This study evaluated the association between roommate exposures and the risk of HAIs.Methods A retrospective cohort of adult patients admitted to a Canadian teaching hospital between June 30, 2001, and December 31, 2005, was studied. Exposures were characterized as total daily roommate exposures and daily unique roommate exposures. Outcomes examined were methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE), and Clostridium difficile.Results The number of roommate exposures per day was significantly associated with MRSA and VRE infection or colonization (MRSA: hazard ratio HR = 1.10, 95\% confidence interval CI = 1.05 to 1.15; VRE: HR = 1.11, 95\% CI = 1.02 to 1.21), and with C difficile infection (HR = 1.11, 95\% CI = 1.03 to 1.19). A significant association also was found for number of unique roommate exposures per day and VRE (HR = 1.15, 95\% CI = 1.02 to 1.28).Conclusions The significant associations found between daily roommate exposures and the infection outcomes suggest a possible role for limiting patient-to-patient contact in an infection prevention and control program in this facility. These findings have implications for the deployment and design of acute care hospitals.
