Burden of traumatic spine fractures in Tehran, Iran

Abstract

BackgroundThe Disability-Adjusted Life Year (DALY) was designed by the World Health Organization (WHO) to measure, compare, and analyze the burden of various diseases. To the best of our knowledge, this is the first study on the assessment of burden of traumatic spinal fracture (TSF) in an Iranian community. We estimated burden of TSF includes both isolated (iTSF) and associated injuries related to traumatic spinal fractures (aTSF) in Tehran, the capital of Iran, for the year 2006-2007 using DALYs.MethodsBurden of TSF was estimated based on information provided by the national data on Iranian trauma, data from the WHO, and literature data using disease modeling (DISMOD). Incidence of TSF and associated injuries were obtained from two population based studies and National Trauma Data Bank in Iran, while duration, and relative risk of mortality (RRM) were obtained from WHO data and the literature. The incidence, duration, and relative risk of mortality (RRM) were used to calculate DALY for TSF. To calculate DALY, the years of life lost because of premature mortality (YLL) were added to the number of years lost because of disability (YLD). DALYs were calculated separately for both iTSF and aTSF. In-hospital YLD and post-hospital YLL for iTSF and in-hospital YLL and YLD were calculated for aTSFs.ResultsTSF incidence was 16.35 (95%CI: 3.4-48.0) per 100,000. The incidence of TSF in males was more than twice that of females. The largest DALYs were seen in 15-29 years. The highest burden of associated injuries of TSF was related to spinal cord and head injury. DALYs for aTSF were estimated to be 2496.9 years (32.0 DALY/100,000 population). The YLD and YLL were almost similar. Total DALY for iTSF and aTSF was 2568.9 years (32.92 DALY/100,000 population). Based on the risk extracted from the literature, post-hospital increased risk of mortality was increased by 1318 DALY (16.89 DALY/100,000 population).ConclusionThis study showed a considerable burden for TSFs mainly due to associated injuries and increased lifelong RRM in patients with TSF.

Incidence and Prevalence of Spinal Cord Injury in Canada: A National Perspective

“…Although there have been no studies that report the incidence and prevalence of SCI in Canada, initial estimates can be obtained using studies that meet these criteria in conjunction with data on Canadian demographics. Using data from other regions to calculate the burden and even incidence and prevalence of disease has proven to be acceptable [17,18]. We estimate the national discharge incidence for TSCI and NTSCI to be 3,675 cases (109 per million) and the prevalence of SCI in Canada to be 85,556 in 2010.…”

Epidemiology of spinal injury in North East India: A retrospective study

“…[ 2 3 ] The incidence of spinal fractures is reported to vary between 16 and 64/100,000 depending on the study area and population concerned. [ 4 5 ] Internationally, most of the injuries are caused by road traffic accidents (RTAs), together with low and high falls. Road traffic and high fall accidents are typical etiology in young patients, whereas the role of low falls and associated osteoporosis increases trauma in older population.…”

Traumatic spine injury in Kashan, Iran

“…Traumatic spine injury (TSI) is a common cause of disability. This injury can result in long-term disability and death (1). Traumatic spine injuries can occur as an isolated lesion or in association with other organ injuries (2).…”

“…The incidence rate of TSI in Iran is 16.35 per 100 000 people. Similar to other types of traumatic injury, the incidence of traumatic spine fracture in males is more than females (1). Also, the prevalence of traumatic spinal cord injury (SCI) in Iran ranges from 1.2 to 11.4 per 10 000 people (3).…”
