Objective: To assess psychometric properties of the European Quality of Life 5-Dimension 3-Level Version(EQ-5D-3L) commonly used tool for measuring road traffic injury (RTI) patients’ quality of life.Methods: The psychometric study assessed the reliability and applicability of EQ-5D-3L through phonesurveys, based on a national cohort platform. Data of 150 RTI patients recruited from the cohort study wereincluded as 50 patients per each follow-up phase (one, six, and twelve months after discharge). A 12- day-timespan was between test and retest. We measured psychometric properties (internal consistency reliability andstability reliability) and agreement using Kappa coefficients and percentages of agreement and Bland-Altmanmethod. Data were analysed using software STATA statistical package.Results: The majority of patients were men (80%) with mean age (SD) of 41(14.7%), employed (78%) andeducated (86%). The Persian version represented high internal consistency reliability at total level (Cronbach’sα=0.81) and moderate to good reliability at phase levels (0.62-0.87). The stability reliability was excellent attotal (ICC=0.98, 95% CI: 0.97, 0.98) and phase levels (0.97-0.98. The kappa agreement coefficients were valuedmoderate to perfect (0.6-0.8, p>0.0001). The Bland-altman plot illustrated high agreement between test andretest scores. No floor and ceiling effects were found.Conclusion: The study revealed that EQ-5D-3L was highly reliable and responsive to be applied through phoneinterviews at three different times post injury and discharge, as no previous study considered its psychometricproperties at various phone follow-ups after RTIs.

Objective: To study the epidemiology of car user road traffic fatalities (CURTFs) during eight years, in East Azerbaijan, Iran.Methods: A total of 3051 CURTFs registered in East Azerbaijan forensic medicine organization database, Iran, during 2006-2014, were analyzed using Stata 13 statistical software package. Descriptive statistics (p<0.05) and inferential statistical methods such as Chi-squared test and multivariate logistic regression with p<0.1 were applied. Results: Of the 7818 road traffic injury (RTI) deaths, 3051 (39%) were car users of whom 71% were male (mean age of 36.7±18.5 years). The majority of accident mechanisms were vehicle-vehicle crashes (63.95%), followed by rollover (26.24%). Crash causing vehicle fall increased the pre-hospital death likelihood by 2.34 times. The prominent trauma causing death was head trauma (in 62.5%). In assessing the role of type of counterpart vehicle on pre-hospital mortality, considering the other cars to be the reference group for comparison, deceased victims were 1.83 times more likely to die before hospital when the counterpart vehicle was a truck and 1.66 times more for buses.Conclusion: Decreasing the car users’ fatalities using appropriate strategies such as separating the roads for heavy and light vehicles and improving the injury related facilitation may be effective. Male drivers with low education could be prioritized for being trained.
