| Abstract|| |
Background: Trauma causes a major burden on the health system and economy of the country. A better understanding of the epidemiology of trauma can be of great help in planning preventive and curative strategies. Materials and Methods: A total of 4834 patients of trauma presenting during 1 year were included in this observational study. Demographic profile and other related criteria were noted, and data were statistically analyzed. Results: Male to female ratio was 5:1; most affected age group was 25–44 years in males and 45–64 years in females; 23.2% were illiterate; and professionals and students were most commonly affected. Road traffic accident (RTA), fall, and assault were the three most common causes; two wheelers were the most common accident causing vehicle. Nearly 17.7% were below poverty line and 67.6% reached hospital within 12 h. Medicolegal cases were 29.7%; only 29.3% reached hospital by ambulance and 3.72% were hemodynamically unstable. Only 3.6% received prehospital care and 16.23% were under alcohol influence. About 23.18% of RTA victims were pedestrians; city roads were the most common accident site. Head injury (25.85%) was the most common associated injury. Fractures were most common in hand (9.72%). The injury severity score (ISS) and New ISS were worse in the patients who were not using seat belt/helmet or were under influence of alcohol. The rate of death and associated injuries was also higher in this group. Conclusion: Trauma is a major preventable cause of mortality and morbidity mainly affecting the productive age group of the society.

| Introduction|| |
Most of the developing countries including India are undergoing rapid modernization and industrialization, which has led to significant increase in the number of automobiles. This has led to rise in number of trauma cases due to road traffic accidents (RTAs), thereby making it a major health hazard. Trauma due to other causes such as injuries at work place, at home, fall, assault, and gunshot injuries also contribute significantly to the overall mortality and morbidity. Previously, it was mainly a problem of the developed countries; but now, developing countries are also undergoing “epidemiology of transition” and hence facing similar challenge. Trauma is the sixth leading cause of mortality and fifth leading cause of morbidity worldwide. It is estimated that 1.2 million people die in RTA alone every year and about 50 million are injured. As a result of ever increasing number of automobiles in developing countries, mortality and morbidity due to RTA is going to become the third most important health problem by 2020., Due to poor documentation, the epidemiology of trauma is not well understood in India. Very few studies are available regarding the epidemiology of trauma in developing countries.,, Since such a large number of trauma cases causes a major burden on the health system and economy of the country, a better understanding of the epidemiology of trauma cases in India can be very helpful in framing better preventive and curative policies.
| Materials And Methods|| |
This is an observational study carried out in the Department of Orthopedics in a tertiary level center in northern India between May 1, 2016 and April 30, 2017. A total of 4834 trauma patients presenting to the accident and emergency of our institute were included in the study. Eighty four days' data were collected; it was collected during 1st week of every month over a period of 1 year. All the patients of orthopedic trauma presenting on the selected days were included in the study; only those patients were excluded from the study who failed to give proper information or who did not have an accompanying family member or relative to give consent or information. All the patients were first appropriately stabilized and given necessary emergency treatment as per the standard protocol. A detailed pro forma was filled for each patient after taking written and informed consent. A detailed history was taken regarding age, sex, mode of injury whether RTA, assault, fall, machine injury, railway track accident, or gunshot injury, education status, occupational and economic status, time lapsed before reaching the hospital, whether medicolegal case or not, mode of reaching the hospital, vitals at the presentation, any prehospital care received, whether riding a vehicle or pedestrian, the accident causing vehicle, whether wearing helmet or seat belt, whether under the influence of alcohol, associated visceral injury, type of orthopedic injury and body region affected, injury severity score (ISS), new ISS (NISS), duration of hospital stay, and mortality rate were noted. The authors certify that the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional or regional) and with the Helsinki Declaration of 1975, as revised in 2000.
At the end of the study, the data were collected and analyzed using Chi-square test and Student's t-test. P < 0.05 was considered as statistically significant.

| Discussion|| |
Since India is a rapidly developing country and currently is one of the fastest growing economies in the world, trauma has become a major health problem. In the total study group, male to female ratio was 5:1. Male predominance was also observed in all the sub-groups with respect to mode of injury. This is comparable to other studies.,,,, Kual et al. reported male to female ratio of 3:1. This could be due to the fact that in our society, males are frequently involved in outdoor activities; most of the times, they are the breadwinners of the family. This also shows the behavioral and social difference in males and females in our society. Males are more exposed to the risk of trauma due to more involvement in automobile driving, labor, sports, and other activities.
Among males, the 25–44 years age group was the most commonly affected in the total study group as well as all other cases of trauma except the fall group where 45–64 years age group was the most commonly involved. Among females, the 45–64 years age group was the most commonly affected in the total study group as well as in RTA and assault; However, 25–44 years age group was the most commonly involved age group in fall, machine injury, and railway track injury. This is comparable to other studies which show that trauma most commonly affects the productive age group.,, In the study by Kual et al., the age group most commonly affected by fatal RTAs was between 25 and 44 years. According to World Health Organization, over 50% of deaths related to RTAs are among the age group 15–44 years.
According to the educational status, 23.2% of the patients were illiterate and remaining were literate; this indicates that the level of education does not reduce the risk for trauma. However, lesser number of patients being postgraduates may be due to the reason that they are more often the indoor working class but this may very well be due to behavioral difference of the persons having higher education level. Professionals (32.62%), students (23.7%), and laborers (15.8%) were the most commonly affected people, indicating that those going outdoors for work or study are more exposed to risk of trauma. Chalya et al. in their study observed that students and businessmen were the two main groups exposed to RTA.
RTA (53.5%) was the most common cause of trauma. This is comparable to other studies from India., This shows irresponsible and erratic driving behavior while driving and at the same time emphasizes lack of law enforcement and road safety. Fall (30%) was another common cause. This is comparable to other studies from India.,, The falls included fall from height at workplace, while sleeping on roof in rural areas, fall from stairs or bed, and fall on floor. This emphasizes the need of safe working conditions for labor and industrial workers and need of building safer houses with proper boundary walls of roof.
Physical assault (11%) was also a major cause. Huda et al. reported assault in 5.4% of the cases. In another study, Ghani et al. reported assault in 3% of cases. The higher incidence of assault may be due to behavioral difference in this region compared to others.
Occupational injuries were 4.5%. Some other studies have reported occupational injuries from 3.7% to 10.5%.,, This emphasizes the need of providing safe environment for people working on machines at their workplace.
Railway track accidents were 0.4% of cases. Rastogi et al. reported railway track accidents in 0.8% of cases. Although this is a small proportion, it is very important because it most often causes fatal or complex injuries.
Gunshot injuries were 0.4% of cases. Rastogi et al. reported gunshot injuries in 1.3% of cases. Huda et al. reported gunshot in 2.08% of cases. Again, these can be associated with vessel injury along with fractures and hence can lead to serious disability and mortality.
Two wheelers (44.9%) were the most common accident-causing vehicle followed by cars (16.2%), trucks (11.2%), buses (10.85%), auto-rickshaw (9.8%), and tractors (3.2%); remaining were by trains and other vehicles. This is comparable to other studies., Ruikar observed that 23.2% of the victims of RTA were two wheeler riders. Madhu et al. observed that two wheelers were involved in 41.3% of accidents. The easier affordability and handling of two wheelers has led to a huge increase in number of these vehicles on the roads but people hardly wear helmets; this along with the fact that other body parts are also unprotected on two wheelers makes these vehicles one of the major reason for RTA-associated injuries.
Patients BPL were 17.7% whereas remaining 82.3% were non-BPL. This BPL group needs health care to be provided at low cost, and appropriate allotment of budget by government is required for treatment of BPL patients. Only 67.6% of the patients reached hospital within 12 h. Dutta et al. observed that 33% of the patients reached hospital within 1 h of injury. Medicolegal cases were 29.7% which indicates trauma causes a huge burden not only on the health system but also on the judicial system of the country. This again is a new observation. Only 29.3% of the total patients reached the hospital by ambulance whereas remaining reached either by personal or hired vehicles. Dutta et al. in a study observed that only 8.3% of the patients reached the hospital by ambulance and another 3% by police vehicle. There is a need to improve the ambulance facility significantly. On reaching the hospital, 3.72% of the patients were hemodynamically unstable. Only 3.6% of the patients received prehospital care by a qualified personnel. There is very strong need for the government to provide adequate qualified healthcare providers at periphery. Overall, 16.23% of total were under the influence of alcohol at the time of injury. Rastogi et al. reported 10.65% patients having alcohol in their blood.
Among RTA victims, 76.4% of the patients were riding a vehicle at the time of injury and remaining 23.6% were pedestrians. This is comparable to some other studies. This highlights that road safety is not only important for the people riding vehicles but it is also important to provide separate safe zones and corridors for the pedestrians who are commonly knocked down by erratic drivers. Rastogi et al. reported 9.6% of the injuries were among pedestrians.
Among vehicle riders, only 19.7% of the patients riding vehicle were using helmet/seat belt. Dutta observed that 20.6% of the patients were wearing helmets at the time of injury. Studies have established protective role of helmets in two wheeler riders., Although enough laws exist for control and punishment in road traffic rule offenders, this is a clear evidence that there is a serious need of strict implementation of these rules.
City roads (32.93%) were the most common site of accidents followed by village roads (11.25%), house (9.62%), farm (8.93%), highway (8.29%), and workplace (7.92%). Ruikar observed that 53.5% of the accidents occurred in rural areas whereas 46.5% occurred in urban areas. This may be due to the fact that city roads are overcrowded by vehicles whereas village roads have relatively less number of vehicles and the highways are improving in terms of safety.
Head injury (25.85%), chest injury (10.6%), pelvic injury (7.24%), and abdominal injury (3.1%) were the common associated injuries. Rastogi et al. reported head injury (57.2%), abdominal injury (31%), chest injury (24.2%), and pelvic injury (7%). ShivaPrakash et al. reported head injury (18.31%), abdominal injury (3.02%), chest injury (1.99%), and pelvic injury (0.96%).
Affected body regions were head (25.85%), shoulder and arm (14.6%), leg and ankle (13.65%), forearm and elbow (11.37%), foot (10.34%), chest (10.06%), hand and wrist (9.72%), thigh and hip (4.13%), abdomen (3.1%), DL spine (3%), pelvis (2.79%), and cervical spine (1.84%). Rastogi et al. in their study reported upper limb injuries in 29.7% cases and lower limb injuries in 28.2% cases. ShivaPrakash et al. reported lower limb injuries in 56.51% of cases and upper limb injuries in 29.87% of cases.
Fractures were most common in hand and carpals (9.72%) followed by radius (7.57%), clavicle (6.82%), tibia (5.99%), fibula (5.44%), ulna (5.35%), femur (4.13%), foot (4.05%), humerus (3.41%), DL spine (3%), acetabulum (2.79%), and cervical spine (1.84%).
Most of the patients (86.36%) were discharged from the hospital within 7 days whereas 107 (2.2%) deaths were reported in the hospital. The ISS and NISS are very good predictor of survival and mortality in trauma patients. We observed that both ISS and NISS were worse in the group of patients who were not using helmet/seat belt or who were under the influence of alcohol at the time of injury. Similarly, the rate of associated injuries and death was also higher in these patients.
| Conclusion|| |
Trauma is a major preventable cause of mortality and morbidity, mainly affecting the productive age group of the society. But a large proportion of trauma can be prevented if appropriate measures are enforced at individual and state levels.
