The increased odds of death in patients with higher initial lactates was significant (odds ratio, 1.02; 95% confidence interval, 1.0003-1.05; P = .04); however, the association was no longer significant when adjusted for time to IVF and antibiotics (P = .51). Based on that observation, the difference in mortality may be due to earlier interventions among patients treated in the specified time frame.
“Patients with lactates drawn within the SEP-1 window received both IV antibiotics and fluids sooner than their counterparts who had lactates drawn outside of the window,” Dr. Han and coauthors explained.
These findings complement prior studies suggesting the benefit of interventions in patients with lactate levels above 2.0 mmol/L, and, conversely, highlight the fact that many patients who meet the severe sepsis criteria nevertheless have normal lactates.
“Although elements of the SEP-1 bundle are useful in managing sepsis, the measure may also lead to an increase in lactate measurements and subsequently excessive utilization of resources on patients who may not benefit,” the researchers wrote.
