Hyperlactatemia has been shown to be related to a higher mortality rate in selected patients admitted in the Intensive Care Units. The aim of this study, published recently, was to evaluate the prognostic property of lactate and to identify a cutoff level of serum lactate for predicting 30-day in-hospital mortality in unselected patients admitted to the Emergency Department. Park et al. also aimed to assess the outcomes in patients with hyperlactatemia defined by the determined cutoff value.
This single center retrospective hospital-based cohort study analyzed patients admitted to the Emergency Department of a Korean tertiary referral hospital. Data was extracted from the electronic medical record system of the hospital.
Park et al. believe that routine blood lactate test in unselected patients may play an important role as a screening tool in the Emergency Department. It could alleviate overcrowding at the Emergency Department by fast decision making on patients with lower risk of poor prognosis, and could contribute to reduce adverse events such as revisiting the Emergency Department and early death after discharge.
The authors of this retrospective cohort study concluded that a serum lactate level greater than 2.6 mmol/L predicted a 30-day in-hospital mortality in unselected patients who arrived at the Emergency Department and were admitted to the hospital. Furthermore, Park et al. consider that serum lactate test in the Emergency Department could be an effective screening method for identifying low risk patients.
