Description
Deng and co-authors asked whether the species of bacteria in a bloodstream infection changes a critically ill patient's risk of delirium, focusing on Staphylococcus aureus. Their 2026 analysis of the MIMIC-IV database covered 3,226 adults with confirmed bloodstream infection, using doubly robust weighting and competing-risk models that treat death as a rival outcome.
Staph infections made up 618 cases, 19.2% of the cohort, and they carried a distinctly higher delirium risk: a subdistribution hazard ratio of 1.39 for delirium within seven days versus Gram-negative infections. The danger concentrated early, reaching 1.60 within the first three days in the acute-window analysis. Methicillin resistance added nothing, with a ratio of 1.12 that was not significant, pointing at the species itself rather than its drug resistance.
