2. Boosting Lactate Measurement in the ED for Early Sepsis Recognition
Context
• We used a collaborative Emergency Department – Critical Care approach to identify
potentially septic patients early, initiate treatment and consult appropriately. This was
implemented in September 2013.
Problem and Issue
• Lactate is a marker of tissue hypoperfusion in sepsis and
should be assessed promptly upon presentation to the
Emergency Department to guide resuscitation
• Lactate is a diagnostic test that is ordered by Emergency
Physicians at their discretion, often after initial blood is
collected by the nurse, thus necessitating an additional ‘poke’
for a specific tube
• Our lab has a 30-minute quality standard from time of
registered receipt of sample in the lab to reporting of result in
the electronic health record
• How could we increase quality measures of lactate
(orderering, time-to-result) for potentially septic patients in
the Emergency Department?

3. Boosting Lactate Measurement in the ED for Early Sepsis Recognition
Actions Taken
• Wide Clinical Variability was found in a 2012 review of 108 septic patients in the
Emergency Department who were admitted to ICU/Step-Up:
 24 (22%) failed to have a lactate ordered by an Emergency Physician, including
7 (29%) of 25 who died during that admission
 Time-from-order-to-result was 0:50+3:37hr despite a 30-minute lab quality
standard
• Engaging Emergency Physicians. The 2012 Surviving Sepsis Guidelines were
presented in Grand Rounds, followed by discussions of the utility of lactate. Barriers
and opportunities were identified, including point-of-care testing.
•
Point-of-Care (POC) Lactate Testing.
 Discussions ensued with vendor, lab services, and Emergency
Department management to streamline lactate ordering, process, and
results.
 Cost analysis deemed POC lactate fiscally prohibitive with current and
projected operational budget

Sepsis Lab Panel
• Prioritizing lactate ordered on syringe vs green top tube
highlighted impact of process, method of collection and
pre-analytical factors influence on lactate, including
reliability and time-to-result with impact on clinical
management
• Collaborative Emergency Department-Laboratory
Medicine approach led to a “Sepsis” Lab bundle with
lactate built in, measured on syringe, and facilitated
under a RN medical directive to mitigate process and
pre-analytical factors
Contribution to Patient Safety & Quality Improvement
• A collaborative approach has led to enhanced monitoring of process and impact on
outcome in all steps of the septic patient journey
• A monthly sepsis scorecard has been designed to monitor performance and outcomes,
while communicating feedback to all stakeholders from the front line in the Emergency
Department to cross-departmental leadership in Emergency, Critical Care, Laboratory
Medicine, and Quality and Risk Management
