Injury patterns among various age and gender groups of trauma patients in southern Iran

Abstract

Administrative data from trauma referral centers are useful sources while studying epidemiologic aspects of injuries. We aimed to provide a hospital-based view of injuries in Shiraz considering victims’ age and gender, using administrative data from trauma research center.A cross-sectional registry-based study of adult trauma patients (age ≥15 years) sustaining injury through traffic accidents, violence, and unintentional incidents was conducted. Information was retrieved from 3 hospital administrative databases. Data on demographics, injury mechanisms, injured body regions, and injury descriptions; outcomes of hospitalization; and development of nosocomial infections were recorded. Injury Severity Score (ISS) was calculated by crosswalking from ICD-10 (International Classification of Diseases) injury diagnosis codes to AIS-98 (Abbreviated Injury Scale) severity codes. Patients were compared based on age groups and gender differences.A total of 47,295 trauma patients with a median age of 30 (interquartile range: 24–44 years) were studied, of whom 73.1% were male and the remaining 26.9% were female (M/F = 2.7:1.0). The most common injury mechanisms in the male group were car and motorcycle accidents whereas females were mostly victims of falls and pedestrian accidents (P < .01). As age increased, a shift from transportation-related to unintentionally caused injuries occurred. Overall, young men had their most severe injuries on head, whereas elderly women suffered more severe extremity injuries. Injury severity was similar between men and women; however, elderly had a significantly higher ISS. Although incidence of nosocomial infections was independent of victims’ age and gender, elderly men had a significantly higher mortality rate.Based on administrative data from our trauma center, male gender and age >65 years are associated with increased risk of injury incidence, prolonged hospitalizations, and in-hospital death following trauma. Development of a regional trauma surveillance system may provide further opportunities for studying injuries and evaluating preventive actions.

Epidemiologic Aspects of Spinal Cord Trauma Cases among Traffic Accident Victims

“…Among the population of this study, 8.3% of traffic accident victims died. Other studies have shown lower hospital mortality rates, ranging from 1.0 in various types of trauma [34] to 3.9% only among victims of traffic accidents [35]. The death rates resulting from traffic accidents decreased in some countries [36,37], including Brazil [38], however, among victims of external causes, traffic accidents were responsible for the majority of deaths [25,39].…”

“…Além disso, é expressiva a publicação de investigações [7][8][9][10]12,[14][15][16][17][23][24][25][26][27][28][29][31][32][33][35][36][43][44][45][46][47][48][49][50] que apontam para uma relação entre morbidade e mortalidade por queda e idade avançada, reforçando a importância de se pesquisar este mecanismo de trauma na população de idosos.…”

“…A presente investigação identificou predomínio do sexo masculino (57,8%) entre as vítimas fatais por queda. Em comparação a outros estudos, alguns mostram prevalência de homens [8][9]17,27,[30][31]33,36,43 enquanto que outros retratam maior frequência de mulheres 10,24,29,32,35 .…”

“…no Brasil aumentou progressivamente conforme a idade, com maior frequência de casos em idosos na faixa etária de 80 anos ou mais (42,4%)22 .Essa relação entre aumento da idade e ocorrência de quedas é evidenciada em outras investigações[23][24][25][26][27] . Estudo realizado em Taiwan 23 mostrou que, de um totalde 4.011 doentes internados por queda, 2.403 (59,9%) tinham idade maior ou igual a 65 anos.…”

“…Estudo realizado em Taiwan 23 mostrou que, de um totalde 4.011 doentes internados por queda, 2.403 (59,9%) tinham idade maior ou igual a 65 anos. No Irã, entre os anos de 2014 e 2015, pacientes com idade superior a 65anos foram, em maior frequência, admitidos em um centro de trauma em decorrência de quedas em comparação aos mais jovens, cujo mecanismo prevalente foi os acidentes de trânsito24 . Três estudos norte-americanos mostraram que os idosos eram mais propensos a quedas do que os jovens[25][26][27] .Segundo estudo canadense28 que analisou 283 vítimas de trauma com idade ≥ 65 anos, a queda é o principal mecanismo de trauma em idosos traumatizados.Alguns fatores aumentam significativamente a probabilidade de trauma por queda em…”
