This research project will examine the impact of implementing a point of care lactate machine on the earlier administration of antibiotics in paediatric patients diagnosed with sepsis in the Emergency Department. Elevated lactate levels have been shown to be an accurate prognostic factor in predicting morbidities among patients with sepsis. Current practice requires serum lactate samples collected via intravenous cannulation, a task that is both time consuming and challenging for paediatric patients and clinicians. The point of care lactate machine is a portable, single operator handheld device, requiring finger-prick blood sample to obtain an accurate lactate result. This negates the need for intravenous cannulation to obtain objective data to aid clinical decision making. This may result in the earlier recognition of sepsis, administration of antibiotics and transfer to definitive care.
