STUDY ON FACTORS AFFECTING MORTALITY IN PATIENTS WITH BRAIN TRAUMATIC INJURIES RESULTING FROM TRAFFIC ACCIDENT BY USING DATA MINING

Abstract

Introduction: One of the most important health problems is road traffic accident. Brain traumatic injury caused by crashes is the first cause of mortality among young people. Capabilities of Data Mining methods to find factor affecting and the prediction therapeutic outcomes leads to the improvement and effectiveness of the services. The aim of this study was to find the Factors affecting mortality in patients with brain traumatic injuries resulting from traffic accident by using the C5.0 decision tree and Bayesian network data mining methods.

Methods: In this cross-sectional study, the population of this study was 106 records of patients with brain traumatic injury caused by traffic accident referred to Khatam-al-Anbia hospital in Zahedan city. Data were collected with a researcher-made checklist that was prepared in consultation with experts in this field and review of previous studies. The validity of this checklist was confirmed by three health information technology experts. Data were analyzed by using two software SPSS MODELER 18.0 and SPSS Statistics 24.

Results:  The accuracy of C5.0 decision tree and Bayesian network were 84.9% and 74.5% obtained. The most important variables that affect the death of accidental patients include Type of lesions, the work of the person in an accident (driver, passenger, pedestrian), accident location (inside or outside the city), and age of the patient. According to the result of this study, the type of lesions with the cause of death (p-value=0.024) is statistically significant.

Conclusion: The results of C5.0 decision tree and Bayesian network showed the most important and effective variable is type of lesions. Hence, by predicting the factors affecting in death of brain traumatic patients, healthcare provider with timely action can reduce the death and irreparable of  injuries to these patients.
