Study population
A retrospective cohort was created from patients admitted to a Canadian tertiary care teaching hospital in southeastern Ontario between April 1, 2001, and March 31, 2006. During the study period, the hospital admitted approximately 17,200 patients per year into 451 in-patient beds. The bed distribution was 107 private beds each in its own room, 166 double-occupancy beds in 83 rooms, 18 triple-occupancy beds in 6 rooms, 76 quadruple- occupancy beds in 19 rooms, as well as 3 open-bay areas in the
Results
Initially, the study population consisted of 94,784 patients and 205,902 patient observations (one observation for every bed occupied by the patient). Ten patients (10 observations) were removed who were not actually admitted to the hospital, 16,865 patients (35,288 observations) were removed for being in one of the in-patient units excluded from the study, 101 patients (162 observations) were removed for being under age 16 years, 3923 patients (8445 observations) were removed because they were
Discussion
The literature on the topic of direct associations between exposure to or the number of hospital roommates and the incidence of HAIs is very limited. While there have been numerous studies on single-occupancy versus multiple-occupancy rooms,10, 11, 14, 32, 33, 34 very few epidemiologic studies investigating the role of hospital roommates in infection/colonization acquisition have been published. The current study supports the hypothesis that for MRSA, VRE, and C difficile, exposure to hospital

2018, The Lancet Infectious DiseasesCitation Excerpt :Second, local-level factors associated with increased antibiotic resistance in hospital settings are under-represented in the literature. For example, the effects of scarce resource allocation on staff-to-patient ratio,63 on infection control practices,64 on inter-staff transmission of pathogens, and on frequency of patient isolation65,66 cannot be concluded from the current literature. At the time of the Review, the increased risk of antibiotic resistance in the health-care setting was predominantly reported to be due to the effects of either previous room occupants,67 or hospital environment or health-care worker contamination.68,69

2016, Clinical Microbiology and InfectionCitation Excerpt :Indeed, more contacts can be counted among patients hospitalized in double-occupancy rooms than those in single-occupancy rooms [2]. Nosocomial bacterial acquisition has been associated with the number of roommate exposures per day [3]. The impact of double-occupancy rooms on HAI in nursing homes has been described retrospectively [4,5], but this risk has not been quantified in acute-care settings prospectively with systematic virologic sampling.
