Study on risk factors and prediction model of skin necrotic infection caused by venomous snake bites
Objective:To analyze the risk factors of skin necrotizing infections caused by venomous snake bites and construct a prediction model.Methods:Clinical data of 99 venomous snake bite patients were retrospectively analyzed to determine whether skin necrotizing infection occurred as an outcome,and predictive model was con-structed and validated using unifactorial and multifactorial logistic regression analysis.Results:Snakebite severity score,blood glucose and D-dimer level were the risk factors of skin necrotizing infections caused by venomous snake bites(all P<0.05).The area under the curve for predicting the occurrence of skin necrotizing infections was 0.92 using the above risk factors to construct a column-line graph prediction model;the calibration curves of the prediction model showed good consistency in both groups.Conclusion:Snakebite severity score,blood glucose and D-dimer levels are risk factors for the occurrence of skin necrotizing infection after venomous snake bites,and the model can provide a reference for clinical decision-making.
