Positive Pleural Fluid Cultures in the ICU: A 10-Year Population-Based Cohort Study of Prevalence, Microbial Characteristics, and Clinical Associations
Listen to this summary
The study aimed to evaluate the prevalence and microbial characteristics of positive pleural fluid cultures in ICU patients, as well as their associations with clinical assessments and 90-day mortality. The findings revealed that while the overall rate of positive cultures was low (4.1%), suspected pleural infections significantly increased the likelihood of a positive culture, which in turn was associated with higher 90-day mortality. This suggests that pleural fluid culturing may be particularly beneficial in cases of suspected infection.
