Concurrent detection of bacterial pathogens in hospital roommates. Nursing Research, 68(1), 80–83. https://doi.org/10.1097/nnr.0000000000000316 Variable and key concepts * Variable and Key Concepts: The article examines the incidence of bacterial pathogens among hospital roommates and then explores environmental contamination as a source of healthcare-associated infections (HAIs). Some basic concepts include sharing a patient room as an avenue or tool for spreading the pathogen and decontaminating to prevent HAIs. Major variables would include the type of bacterial pathogen detected, such as Staphylococcus aureus and Pseudomonas aeruginosa, along with the timing of positive cultures. * Hypotheses: Although the hypothesis is not clearly stated, it might be assumed from the article that shared hospital rooms might bring about the risk of pathogen transmission between roommates. * Research Question: The critical question is whether the shared room was a transmission risk factor for bacterial infectious agents among the patients. The question is straightforward, leading to the design of this study and...
