Evaluation of pre-hospital point-of-care testing for lactate in sepsis and trauma patients

Objective: Lactate is a significant marker of critical illness and mortality in sepsis and trauma patients. The purpose of this study is to evaluate point-of-care lactate testing by paramedics in a UK ambulance service.
Methods: Selected enhanced care paramedics were trained to use the lactate meter in patients with suspected sepsis and patients who trigger the major trauma bypass protocol. Feedback was collected on the practicalities of using the meter and the potential impact on the diagnosis of sepsis.
Results: Data were collected on 114 patients, 96% had suspected sepsis (n=109) and 4% (n=5) were patients who had sustained trauma. The participants found that the ability to take lactate readings was useful and increased their confidence in their clinical decision making.
Conclusions: Point-of-care lactate measurement is feasible in pre-hospital care and appears to support paramedics in their decision making.
