IMPORTANCE: Contact precautions are widely used to prevent the transmission of carbapenem-resistant organisms (CROs) in hospital wards. However, evidence for effectiveness in natural hospital environments is limited. OBJECTIVE: To determine which contact precautions, healthcare-worker-patient interactions, and patient and ward characteristics are associated with greater CRO infection or colonization risk. DESIGN, SETTING, AND PARTICIPANTS: CRO clinical and surveillance cultures from two high-acuity wards were assessed through probabilistic modeling to characterize a susceptible patient's risk of CRO infection or colonization during ward stay...
