Summary: | The aim of this study is to analyze the accuracy of the two classification systems for open fractures most commonly used in current medical practice, Gustilo and Tscherne, as predictors of infection.
A retrospective observational study was performed, including 121 patients suffering from open fracture of the appendicular skeleton treated at an emergency hospital. The fractures were classified according to Gustilo and Tscherne systems during the initial treatment, and ratings were subsequently confirmed or rectified during hospitalization. Sensitivity, specificity, positive and negative predictive values, and accuracy were calculated according to each classification adopted.
The results of this study demonstrated that both classifications of Gustilo and Tscherne are associated with the clinical outcome of infection in open fractures. The Gustilo classification achieved sensitivity of 76.7%, specificity of 53.8%, and accuracy of 59.5%. Tscherne's classification had a sensitivity of 56.7%, specificity 82.4%, and accuracy of 76.1%.
The Tscherne system showed better accuracy, including specificity as a predictor of infection in open fractures, when compared with the Gustilo system.
Analisar comparativamente a acurácia dos dois sistemas para classificação de fraturas expostas mais usados na prática médica atual, Gustilo e Tscherne, como preditores de infecção nas fraturas expostas.
Foi feito um estudo observacional retrospectivo com 121 indivíduos acometidos por fratura exposta do esqueleto apendicular atendidos em uma unidade de emergência hospitalar. As fraturas expostas foram classificadas segundo os dois sistemas durante o atendimento inicial; as classificações eram posteriormente confirmadas ou retificadas durante o internamento. Foram calculados sensibilidade, especificidade, valores preditivos positivos e negativos e acurácia, segundo cada classificação adotada.
Os resultados demonstraram que ambas as classificações, de Gustilo e de Tscherne, apresentam associação com o desfecho clínico infecção em fraturas expostas. A classificação de Gustilo obteve sensibilidade de 76,7%, especificidade de 53,8% e acurácia de 59,5%. A classificação de Tscherne obteve sensibilidade de 56,7%, especificidade de 82,4% e acurácia de 76,1%.
O sistema de classificação de Tscherne demonstrou maior acurácia, apresentou melhor especificidade como preditor de infecção em fraturas expostas quando comparado com o sistema de Gustilo. |
