Description
Summary:Study objective: No research tool exists for the clinical evaluation of crotalid snakebite. We sought to determine the correlation of the snakebite severity score (SSS) with the clinical assessment of physicians experienced in the management of crotalid snakebite. Methods: We retrospectively used the SSS to quantify the severity of envenomation in 108 patients with crotalid snakebite. Two physicians experienced in the management of venomous snakebite independently and blindly assessed the severity of envenomation as detailed in medical records with the use of accepted clinical criteria. The correlation of the SSS and the physicians’ consensus was determined with pointbiserial correlation. Results: The SSS correlated well with the physicians’ consensus at presentation (r=+.63, z score=6.52, P
