Risk Factor Analysis and Predictive Modeling for Necrotizing Skin Infections in Venomous Snakebite Patients: A Multicenter Retrospective Study
Risk Factor Analysis and Predictive Modeling for Necrotizing Skin Infections in Venomous Snakebite Patients: A Multicenter Retrospective Study
This multicenter retrospective study aims to identify the risk factors associated with necrotizing skin infections following venomous snakebites and to develop a predictive model. Clinical data from 99 patients treated between January 2020 and April 2024 at three hospitals in Guangdong Province, China, were analyzed.
Venomous snakebites are a significant public health issue, particularly in tropical and subtropical regions like southern China. Necrotizing skin infections are a severe but relatively rare complication of venomous snakebites, often resulting from delayed treatment and bacterial invasion. This study retrospectively analyzed clinical data from 99 patients with venomous snakebites treated at three hospitals in Guangdong Province between January 2020 and April 2024. The primary objective was to identify the major risk factors associated with the development of necrotizing skin infections and to build a predictive model to assist in clinical decision-making.
The study included male and female patients aged 14 years and older. Patients with incomplete medical records, long-term use of immunosuppressants, or underlying immunodeficiency diseases were excluded. Multivariate logistic regression identified the Snakebite Severity Score (SSS), blood glucose levels, and D-dimer levels as significant independent predictors of necrotizing infections.
