The risk of being involved in a fatal traffic accident was higher for those injured between 4:00 to 7:59 than at other times (OR equal to 2.13, 95% CI 1.85-2.44). The greatest number of fatal RTAs took place in summer. Mortalities due to RTA during spring and summer were more pronounced at 20:00 to 23:59 and midnight to 3:59, whereas mortalities in fall and winter were more pronounced from 12:00 to 15:59.</p><p><b>CONCLUSION</b>The high mortality rate of RTA is a major public health problem in Fars Province.

An epidemiologic survey of road traffic accidents in Iran: analysis of driver-related factors / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>Road traffic accident (RTA) and its related injuries contribute to a significant portion of the burden of diseases in Iran. This paper explores the association between driver-related factors and RTA in the country.</p><p><b>METHODS</b>This cross-sectional study was conducted in Iran and all data regarding RTAs from March 20, 2010 to June 10, 2010 were obtained from the Traffic Police Department. We included 538 588 RTA records, which were classified to control for the main confounders: accident type, final cause of accident, time of accident and driver-related factors. Driver-related factors included sex, educational level, license type, type of injury, duration between accident and getting the driving license and driver's error type.</p><p><b>RESULTS</b>A total of 538 588 drivers (91.83% male, sex ratio of almost 13:1) were involved in the RTAs. Among them 423 932 (78.71%) were uninjured; 224 818 (41.74%) had a diploma degree. Grade 2 driving license represented the highest proportion of all driving licenses (290 811, 54.00%). The greatest number of accidents took place at 12:00-13:59 (75 024, 13.93%). The proportion of drivers involved in RTAs decreased from 15.90% in the first year of getting a driving license to 3.13% after 10 years'of driving experience. Neglect of regulations was the commonest cause of traffic crashes (345 589, 64.17%). Non-observance of priority and inattention to the front were the most frequent final causes of death (138 175, 25.66% and 129 352, 24.02%, respectively). We found significant association between type of accident and sex, education, license type, time of accident, final cause of accident, driver's error as well as duration between accident and getting the driving license (all P less than 0.001).</p><p><b>CONCLUSION</b>Our results will improve the traffic law enforcement measures, which will change inappropriate behavior of drivers and protect the least experienced road users.</p>

Epidemiological characteristics of fatal pedestrian accidents in Fars Province of Iran: a community-based survey / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To determine the epidemiological characteristics of fatal pedestrian accidents in Fars Province of Iran.</p><p><b>METHODS</b>This cross-sectional study was conducted in Fars Province of Iran during a 29-month period from March 2009 to July 2011. The data were from the Fars Forensic Medicine Registry. In 4 923 recorded road traffic accident fatalities, 971 deaths were due to pedestrian accidents. The demographic and accident-related information were analyzed by SPSS version 11.5. P value less than 0.05 was considered significant.</p><p><b>RESULTS</b>The mean age of decedents was (47.2+/-26.2) years, ranging from 6 months to 103 years old. Males accounted for 69.8% of all deaths. Fatal accidents were most common in September; 56.1% of the fatal injuries occurred on intracity roads and 33.1% on extracity roads. Fatal head injuries were present in 60.54% of cases. Evaluation of the injury site and the cause of death found that they were significantly associated with age, interval between injury and death. Besides, the type of roads played an important role in mortality.</p><p><b>CONCLUSION</b>Although the clinical management of trauma patients has been improved in our country in the recent decade, decreasing the burden of injuries needs coordination among trauma system organizations.</p>
