•Prolonged infusion (PI) of β-lactam was associated with a lower mortality in sepsis.•PI was not commonly applied and was more often used in severely ill patients.•PI had a survival benefit independent of disease severity. β-lactams are the most widely used antibiotics in sepsis. We aimed to explore the factors that drive physicians to choose prolonged infusion (PI) of β-lactams in septic patients. This prospective observational national cohort study was conducted in 40 ICUs at the teaching hospitals of 31 provinces in China between August 20, 2021 and September 20, 2021. Of the 441 enrolled patients, 265 (60.09%) received PI therapy. Multivariate analysis showed that multidrug-resistant bacterial infection and septic shock were independent factors associated with PI. However, our data showed that the survival benefit of PI use was evident in subgroups with less severe sepsis, including those with lower Charlson comorbidity index values (
