Purpose:Trauma is an inevitable part of the health burden in every country. Both the preventive and rehabilitative aspects of traumatic injuries are expensive. Since most of the injuries happen in low- and middle-income developing countries, a judicious allocation of the limited resources to the most costefficient strategies is necessary. The present study was designed to report the causes of trauma, injured body regions, trauma severity scores and the one year survival rate of a randomly selected sample of trauma patients in a major referral hospital in Tehran, Iran.Methods:We chose and analyzed a random subgroup of traumatic patients admitted during the oneyear period of May 2012 to May 2013 to Shariati Hospital, a major University Teaching Hospital in Tehran, Iran. Patients who stayed at the hospital for less than 24 h were excluded. In total, 73 traumatic patients were registered. The mean age was (40.19 ± 20.34) years and 67.1% of them were male.Results:In general, the most common cause of injury was falls (47.9%), followed by road traffic crashes (RTCs, 40.8%). Assault and exposure to inanimate mechanical forces each were only associated with 5.6% of all injuries. The only cause of injury in ages of more than 65 years was fall. The most common cause of injury in ages between 15 and 45 years was RTCs. During the study, two deaths occurred: one was at ICU and the other was at home. The most commonly injured body region was the head (23.8%), followed by the elbow and forearm (19%), hip and thigh (15.9%), and multiple body regions (14.3%). The mean abbreviated injury score was 2.23 ± 1.02; injury severity index was 7.26 ± 7.06; and revised trauma score was 7.84, calculated for 38 patients.Conclusion:Prevention strategy of traumatic injury should focus on falls and RTCs, which are respectively the most common cause of trauma in older aged people and young males.

Spatial analysis of driving accidents leading to deaths related to motorcyclists in Tehran

Chinese Journal of Traumatology 2019年第3期22卷 148-154页

Purpose: Traffic accidents are one of the main causes of death and disability, causing annual deaths of 1.23 million and tens of millions injured people worldwide. Meanwhile, a significant proportion of the deaths and injuries caused by traffic accidents occur among motorcyclists. According to the world health organization's 2015 report, about 25% of deaths from traffic accidents occur in motorists. In Iran, a significant proportion of deaths and injuries result from traffic accidents among motorcyclists, especially in passages within the cities. According to traffic police, about 25% of deaths and 50% of injuries in traffic accidents of Tehran are reported among motorcyclists. Therefore, due to the importance of this issue, the spatial factors influencing the incidence of motorcycle-related accidents in Tehran were investigated using the geographic information system. Methods: The present work was a cross-sectional and descriptive analysis study. The data necessary for the study were extracted from Tehran traffic police as well as municipality databases. Zoning maps were used to display the distribution of events. In the analytical investigation, Moran index was used to determine the distribution pattern of the events, while Getis-Ord G^* statistics were applied to analyze hot spots. To investigate the role of regional and environmental factors in the frequency of traffic accidents related to motorcyclists in geographic units (Tehran 22 districts), Poisson regression and negative binomial models were used. The geographically weighted regression (GWR) model was used to analyze the relationship between environmental factors and the location of these events. Statistical analyses were performed using SPSS, STATA, ARC-GIS and GWR software. Results: The southern and eastern margins of Tehran are the most vulnerable areas in terms of deaths related to traffic accidents of motorcyclists. Highways are considered the location of most traffic accidents which lead to death of

Objective: Injuries are common and important problem in Tehran, capital of Iran. Although therapeutic centers are not essentially established following the constructional principles of developed countries, the present opportunities and equipments have to be used properly. We should recognize and reduce the deficits based on the global *** study deliberates the trauma resources and capacities in university hospitals of Tehran based on Arizona trauma center standards, which are suitable for the assessment of trauma ***: Forty-one university hospitals in Tehran were evaluated for their conformity with "Arizona trauma center standards" in 2008. A structured interview was arranged with the "Educational Supervisor" of all hospitals regarding their institutional organization, departments, clini-cal capabilities, clinical qualifications, facilities and resources, rehabilitation services, performance improvement, continuing education, prevention, research and additional requirements for pediatric trauma patients. Relative frequencies and percentages were calculated and Student's t test was used to compare the mean ***: Forty-one hospitals had the average of 77.7 (50.7%) standards from 153 Arizona trauma center standards and these standards were present in 97.5 out of 153 (63.7%) in 17 general hospitals. Based on the subgroups of the standards, 64.8% items of hospital resources and capabilities were considered as a subgroup with the maximum criteria, and 17.7% items of research section as another subgroup with the minimum ***: On the basis of our findings, no hospital meet all the Arizona trauma center standards completely. The hospitals as trauma centers at different levels must be promoted to manage trauma patients desirably.

作者： Mohammad R Rasouli Mohsen Nouri Mohammad-Reza Zarei soheil saadat Vafa Rahimi-Movaghar Trauma and Surgery Research Center Sina HospitalMedical Sciences/University of Tehran Tehran Iran

Objective To compare fatalities and injuries in road traffic crashes (RTC) in Iran with other countries. Methods Data were obtained from national health sources of Iran. These data included population number, registered motor-vehicles number, number of RTCs and consequent fatalities and injuries from 1997 to 2006. Results RTC fatality and injury rates increased from 1997 to 2005, but decreased in 2006. The over all men/women ratio in the RTC fatalities was 4.2:1. High RTC fatality rate of 39 per 100 000 population in Iran was almost the same as some other developing countries. In Iran, RTC fatalities in recent years were almost twice as much as the highest rate among the European countries. Conclusions This investigation shows that in spite of reduction of RTC fatality in Iran in 2006, it is still one of the highest in the world. Moreover, this paper describes the state of RTC-related parameters in a developing country in comparison with the developed countries.
