Through the multivariable analyses, clinical impacts of delayed AAT, assessed by the time gap between the first dose of AAT and ED arrival, on 30-day mortality (primary outcomes) were respectively examined in the different groups of initial BTs (iBTs).Results: Of the 3171 adults, despite the similarities of delayed AAT in six iBT categories, hourly AAT delay was associated with an average increase in 30-day mortality rates of 0.24% in the group of iBT < 36.0℃, 0.40% in the 36.0℃– 36.9℃ group, 0.48% in the 37.0℃– 37.9℃ group, 0.59% in the 38.0℃– 38.9℃ group, 0.58% in the 39.0℃– 39.9℃ group, and 0.71% in the ≥ 40.0℃ group, after respective adjusting independent predictors of mortality. Furthermore, for 589 patients who inappropriately received empirical antimicrobial treatment (ie, delayed AAT ≥ 24 hours), with a cutoff of 34.0℃, each 1℃ increase in iBTs was independently associated with an average increase in 30-day mortality rates of 42%.Conclusion: For adults with community-onset bacteraemia, the iBT-related differences in the prognostic impacts of delayed administration of appropriate antimicrobials might be evident.Keywords: body temperature, empirical, antibiotic, community-onset, bloodstream infection, mortality
