Kao KC, et al. - In patients with acute respiratory distress syndrome (ARDS) caused by influenza pneumonia, researchers investigated the survival predictors of prone positioning. This multicenter retrospective cohort study was conducted by eight tertiary referral centers in Taiwan. All patients in intensive care units with virology-proven influenza pneumonia were collected from January 1 through March 31, 2016; patients with ARS who received prone positioning were enrolled. Findings revealed pneumonia severity index, renal replacement therapy, and increase in dynamic driving pressure were associated with 60-day mortality in patients with influenza pneumonia-related ARDS receiving prone positioning.
