Clinical Science Aspects

Aim: This study aimed to identify whether quick sequential organ failure assessment (qSOFA) performed immediately upon arrival can predict the outcome of patients with glyphosate surfactant herbicide (GlySH) poisoning.

Methods: Adult patients with GlySH poisoning between January 2006 and April 2017 were included in this retrospective observational study. The qSOFA score (respiratory rate ≥22 breaths per minute, systolic blood pressure <100 mm Hg, and altered mental status) was assessed immediately upon arrival at the emergency department. The primary outcome was in-hospital mortality, and the secondary outcomes were life-threatening complications and organ injury.

Results: Of the 150 patients who ingested GlySH, 14 (9.3%) died. The qSOFA score was significantly higher in the non-survival group (P < 0.001). qSOFA (odds ratio [OR], 2.73; 95% confidence interval [CI], 1.41–5.76) was independently associated with in-hospital mortality. The area under curve value of qSOFA was 0.841 (95% CI, 0.772–0.895). As qSOFA score increased from 0 to 3, the in-hospital mortality significantly increased (P < 0.001). The frequency of life-threatening complications, including organ injury, increased as the qSOFA score increased from 0 to 3 (P < 0.001).

Conclusions: The qSOFA score measured upon arrival shows good prognostic performance in patients with GlySH poisoning. Moreover, the qSOFA may predict the development of life-threatening complications including organ injury. Thus, more attention should be paid to patients with GlySH poisoning with higher qSOFA scores.
