Despite prior research demonstrating higher injury-mortality rates among rural populations, few studies have examined the differences in nonfatal injury risk between rural and urban populations. The objective of this study was to compare injury-hospitalization rates between rural and urban populations using population-based national estimates derived from patient-encounter data.
A cross-sectional analysis of the 2004 Nationwide Inpatient Sample was conducted in 2007. Rural-urban classifications were determined based on residence. SUDAAN software and U.S. Census population estimates were used to calculate nationally representative injury-hospitalization rates. Injury rates between rural and urban categories were compared with rate ratios and 95% CIs.
An estimated 1.9 million (95% CI=1,800,250-1,997,801) injury-related hospitalizations were identified. Overall, injury-hospitalization rates generally increased with increasing rurality; rates were 27% higher in large rural counties (95% CI=10%, 44%) and 35% higher in small rural counties (95% CI=16%, 55%). While hospitalization rates for assaults were highest in large urban counties, the rates for unintentional injuries from motor vehicle traffic, falls, and poisonings were higher in rural populations. Rates for self-inflicted injuries from poisonings, cuttings, and firearms were higher in rural counties. The total estimated hospital charges for injuries were more than $50 billion. On a per-capita basis, hospital charges were highest for rural populations.
These findings highlight the substantial burden imposed by injury on the U.S. population and the significantly increased risk for those residing in rural locations. Prevention and intervention efforts in rural areas should be expanded and should focus on risk factors unique to these populations.

    • "Several studies investigating urban– rural differences among children and adolescents have reported higher rates in rural settings (Carey et al. 1993; Danseco et al. 2000; Hammig and Weatherley 2003; Owen et al. 2008; Singh et al. 2012). There are also studies that have shown no significant differences (Overpeck et al. 1997; Ni et al. 2002; Coben et al. 2009), and higher rates of injuries among children in urban areas (Gilbride et al. 2006).

    ABSTRACT: Previous work has explored the significance of residence on injuries. A number of articles reported higher rates of injury in rural as compared to urban settings. This study aimed to evaluate the importance of residency on the occurrence of fractures among children and adolescents within a region in northern Sweden. In a population based study with data from an injury surveillance registry at a regional hospital, we have investigated the importance of sex, age and place of residency for the incidence of fractures among children and adolescents 0-19 years of age using a Poisson logistic regression analysis. Data was collected between 1998 and 2011. The dataset included 9,965 cases. Children and adolescents growing up in the most rural communities appeared to sustain fewer fractures than their peers in an urban municipality, risk ratio 0.81 (0.76-0.86). Further comparisons of fracture rates in the urban and rural municipalities revealed that differences were most pronounced for sports related fractures and activities in school in the second decade of life. Results indicate that fracture incidence among children and adolescents is affected by place of residency. Differences were associated with activity at injury and therefore we have discussed the possibility that this effect was due to the influence of place on activity patterns. The results suggest it is of interest to explore how geographic and demographic variables affect the injury pattern further.

    • "There was a significant difference between Finnmark and the other areas in the data from Statistics Norway. This category did not follow an urban-rural gradient, which is in line with higher suicide rates being reported in rural communities [3,14,15], whereas other studies have identified this as an urban problem [16]. This study does not report suicides committed by poisoning, and thus the complete picture is not provided. "

    ABSTRACT: Background Many studies indicate rural location as a separate risk for dying from injuries. For decades, Finnmark, the northernmost and most rural county in Norway, has topped the injury mortality statistics in Norway. The present study is an exploration of the impact of rurality, using a point-by-point comparison to another Norwegian county. Methods We identified all fatalities following injury occurring in Finnmark between 2000 and 2004, and in Hordaland, a mixed rural/urban county in western Norway between 2003 and 2004 using data from the Norwegian Cause of Death Registry. Intoxications and low-energy trauma in patients aged over 64 years were excluded. To assess the effect of a rural locale, Hordaland was divided into a rural and an urban group for comparison. In addition, data from Statistics Norway were analysed. Results Finnmark reported 207 deaths and Hordaland 217 deaths. Finnmark had an injury death rate of 33.1 per 100,000 inhabitants. Urban Hordaland had 18.8 deaths per 100,000 and rural Hordaland 23.7 deaths per 100,000. In Finnmark, more victims were male and were younger than in the other areas. Finnmark and rural Hordaland both had more fatal traffic accidents than urban Hordaland, but fewer non-fatal traffic accidents. Conclusions This study illustrates the disadvantages of the most rural trauma victims and suggests an urban-rural continuum. Rural victims seem to be younger, die mainly at the site of injury, and from road traffic accident injuries. In addition to injury prevention, the extent and possible impact of lay people’s first aid response should be explored.

    • "This rural county (48,000 km2) is comparable in size to Belgium but with a population of 72,500 [2]. Rural areas have a higher rate of injury-related deaths than urban areas [3–6], which has been attributed to longer travel distances, delayed surgical care, fewer personnel trained in advanced life support techniques, and behavioral patterns among the populace [7–11]. Finnmark has had an injury-related death rate well above the national average for decades (Fig. 1). "

    ABSTRACT: Finnmark County is the northernmost county in Norway. For several decades, the rate of mortality after injury in this sparsely inhabited region has remained above the national average. Following documentation of this discrepancy for the period 1991-1995, improvements to the trauma system were implemented. The present study aims to assess whether trauma-related mortality rates have subsequently improved. All injury-associated fatalities in Finnmark from 1995-2004 were identified retrospectively from the National Registry of Death and reviewed. Low-energy trauma in elderly individuals and poisonings were excluded. A total of 453 cases of trauma-related death occurred during the study period, and 327 of those met the inclusion criteria. Information was retrievable for 266 cases. The majority of deaths (86%) occurred in the prehospital phase. The main causes of death were suicide (33%) and road traffic accidents (21%). Drowning and snowmobile injuries accounted for an unexpectedly high proportion (12 and 8%, respectively). The time of death did not show trimodal distribution. Compared to the previous study period, there was a significant overall decline in injury-related mortality, yet there was no change in place of death, mechanism of injury, or time from injury until death. Changes in injury-related mortality cannot be linked to improvements in the trauma system. There was no change in the epidemiological patterns of injury. The high rate of on-scene mortality indicates that any major improvement in the number of injury-related deaths lies in targeted prevention.
