Abstract

Background: One of the leading causes of death, especially in developing countries, is road traffic accident. The Glasgow coma scale, age, systolic blood pressure (GAP) scoring system is a quantitative method to predict the mortality of trauma patients. Considering the importance of preventing deaths caused by road traffic accidents, this study aims to predict the mortality of road traffic injured patients admitted to a hospital in Isfahan, Iran in 2019 using the GAP score. Materials and Methods: This is a cross-sectional study using the exiting data. The study population included all road traffic injured people transferred to Ayatollah Kashani Hospital in Isfahan by the emergency medical services (EMS) ambulances during November and December, 2019 and January, 2020 (n=2674). The medical files of 1985 injured were finally included in this research. A researcher-made checklist was used to collect data. Descriptive statistics were used to present the data and the receiver operating characteristic (ROC) curve was used to evaluate the accuracy of the scoring system. Results: Based on the GAP score, 19 people (0.98%) were in the high-risk group, 1267(63.81%) in the moderate-risk group, and 699(35.21%) were in the low-risk group. It was found that 4 people from the high-risk group (21%), 7 from the moderate-risk group (1%) and 3 from the low-risk group (1%) had died. The best cut-off point of the GAP score in predicting short-term (24-hour) road traffic mortality was 15 and with a sensitivity of 96%. Conclusion: Most of death cases in road traffic injured patients referred to Ayatollah Kashani Hospital during three months were related to the high-risk groups (GAP score: 3-10). The GAP score can predict the hospital mortality of road traffic injuries accurately and easily. © 2025 The Author(s).
