What does this research mean for the field?

Early warning scores such as WPSS, MEWS, NEWS, and RAPS demonstrate limited-to-moderate discriminatory ability for predicting adverse clinical outcomes in snake bite patients and should be used as complementary rather than standalone clinical decision-making tools. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate whether standard early warning scores (RAPS, REMS, MEWS, WPSS, and NEWS) can accurately predict envenomation severity and adverse clinical outcomes in emergency department snakebite patients.

Overview

Retrospective observational study finds early warning scores predict envenomation severity but poorly forecast adverse outcomes in snakebite patients, suggesting complementary clinical utility.

Key Points

To evaluate whether standard early warning scores (RAPS, REMS, MEWS, WPSS, and NEWS) can accurately predict envenomation severity and adverse clinical outcomes in emergency department snakebite patients.
Retrospective observational study of consecutive patients (N=84) presenting with snakebites to a university hospital emergency department between 2014 and 2024.
Evaluated adverse clinical outcomes—defined as the need for high-dose antivenom, blood product transfusion, and prolonged hospitalization—using receiver operating characteristic (ROC) curve analysis.
For distinguishing Grade 2–3 envenomation severity, scores demonstrated high discriminatory value: WPSS (AUC: 0.890 [95% CI: 0.762–0.963]), MEWS (AUC: 0.854 [95% CI: 0.718–0.940]), NEWS (AUC: 0.852 [95% CI: 0.716–0.939]), and RAPS (AUC: 0.750 [95% CI: 0.600–0.866]).
Predictive performance was weak across all adverse clinical outcomes (all p < 0.05), with AUCs of 0.613–0.687 for high-dose antivenom, 0.669–0.680 for blood transfusion, and 0.629–0.674 for prolonged hospital stay.
Among all patients, 47.6% required ward admission and 34.5% required intensive care unit admission, with no reported deaths.
