Comparison of hip fracture incidence and trends between Germany and Austria 1995-2004: An epidemiological study

Mann E, Meyer G, Haastert B, Icks A. Comparison of hip fracture incidence and trends between Germany and Austria 1995-2004: an epidemiological study. BMC Public Health. 2010;10(1): 46.Background Several studies evaluated variations in hip fracture incidences, as well as trends of the hip fracture incidences. Comparisons of trends are lacking so far. We compared the incidence rates and, in particular, its trends between Austria and Germany 1995 to 2004 analysing national hospital discharge diagnosis register data. Methods Annual frequencies of hip fractures and corresponding incidences per 100,000 person years were estimated, overall and stratified for sex and age, assuming Poisson distribution. Multiple Poisson regression models including country and calendar year, age and sex were used to analyse differences in incidence and trend. The difference of annual changes between the two countries was explored using an interaction term (calender year * country). Results Overall, the increase of hip fracture risk was 1.31 fold higher (95% CI 1.29-1.34) in Austria compared to Germany, adjusted for age, sex, and calendar year. The risk increase was comparable for both sexes (males: RR 1.35 (1.32-1.37), females: RR 1.31 (1.29-1.33)). Hip fracture trend from 1995 to 2004 indicates an increase in both countries without a statistically significant difference between Austria and Germany (interaction term: p = 0.67). Conclusion In this study comparing hip fracture incidences and its trend using pooled data, the incidence in Austria was 30% higher compared to its neighbouring country Germany. For both countries a similar increasing trend of hip fracture incidence over the 10-year study period was calculated. The results need confirmation by other studies

Severe traumatic brain injury in Austria II: Epidemiology of hospital admissions

OBJECTIVES: The goal of this paper is to describe the hospital-based epidemiology of severe TBI in Austria. PATIENTS AND METHODS: Data sets from 492 patients included in the study by 5 Austrian hospitals were available. Age and gender distribution, education, occupation, location of trauma, mechanism of injury, alcohol use, type and severity of injury, associated injuries, length of intensive care unit stay, and intensive care unit outcome were evaluated for each of the 5 centers. RESULTS: The sample represents roughly 13% of all cases with severe TBI which were treated in Austrian hospitals during the study period. Mean age was 48 ± 21 years, and most patients were male (72%). The most important trauma locations were roads (50%), home (24%), outdoors (10%), and workplace (7%). Transportrelated trauma was the most important mechanism (44%) followed by falls 3 m (11%), and sports injuries (5%). Detailed analysis of transport-related trauma showed that car accidents (45%) were most common, followed by pedestrian (20%), motorbike (19%), and bicycle (16%) accidents. Significant differences between the centers were found for most of the variables analyzed. The severe traumatic brain injury was associated with spinal cord injury in 10%, and with severe multiple trauma in 38% of cases. Intensive care mortality was 31.7%. There were no significant correlations between mechanisms of injury and severity of trauma, nor between mechanisms and ICU outcome. CONCLUSIONS: Epidemiology of severe traumatic brain injuries in Austria is not much different from other industrialized countries. Traffic accidents are responsible for the majority of traumas, stressing the importance of road injury prevention. Attention should also be paid to the specific risks of older people and to prevent injuries at home. © 2007 Springer-Verlag
