Background Sepsis is a complex disease process that possesses a socioeconomic burden in the U.S.¹ Serum lactate and lactate clearance form an important component of the sepsis resuscitation bundle² and high levels correlate with worse outcomes.^{3 4 5} Previous studies emphasized the importance of utilizing lactate monitoring to guide resuscitation to improve mortality.^{6 7}

Objectives We aimed to enhance lactate monitoring and lactate guided resuscitation in sepsis patients with lactate levels ≥2 mmol/L in order to improve outcomes.

Methods An EMR automated Q2 lactate repeat orders for sepsis patients who have an initial lactate level ≥2 mmol/L was implemented. Lactate dashboards showing all patient-level lactate values during initial resuscitation was incorporated into Hospital Sepsis Committee Multi-Disciplinary meetings.

Results We included 1774 adult sepsis patients admitted from the ED to MICU from October 2014 to September 2018 who had an initial lactate level ≥2 mmol/L. We aimed to compare the median time from ED arrival to lactate reduction to <2 mmol/L, median time from 1st elevated lactate result to lactate <2 mmol/L and the median length of stay (LOS). Post-intervention, the time from ED arrival to lactate <2 mmol/L for those patients with an elevated lactate significantly reduced by 10.56 hours and the time from first elevated lactate to lactate <2 mmol/L significantly reduced by 9.51 hours. LOS reduced by 3 days post intervention.

Conclusions Implementing an automated repeat lactate order for sepsis patients along with a multi-disciplinary review of dashboards resulted in an improvement in lactate clearance and a reduction in LOS. Further studies are needed to investigate this finding.
