Point-of-Care Lactate Testing Predicts Mortality of Severe Sepsis in a Predominantly HIV Type 1– Infected Patient Population in Uganda

Background. Prediction of mortality may improve management and outcomes of patients with sepsis in resource-limited settings. Therefore, we evaluated the ability of a hand-held portable whole-blood lactate (PWBL) analyzer to predict mortality of patients who are admitted to the hospital with severe sepsis. Methods. A prospective observational study enrolled 253 patients at a national referral hospital in Uganda. Inclusion criteria required (1) ⩾2 systemic inflammatory response syndrome criteria or thermodysregulation, (2) hypotension, and (3) suspected infection. A subset of 72 patients had PWBL and standard laboratory serum lactate measured. The primary measured outcome was in-hospital mortality. Results. Fifty-nine (81.9%) of 72 evaluated patients were infected with human immunodeficiency virus type 1. The in-hospital mortality rate was 25.7% (18 of 70), and the in- and outpatient mortality at 30 days was 41.6% (30 of 72). PWBL was positively associated with in-hospital but not outpatient mortality (P
