This study is an investigation into the epidemiologic and socioeconomic impact of osteoporosis-associated hip fractures in Austria. We determined age- and gender-specific incidence rates of osteoporosis-associated hip fractures for all patients treated in hospitals in 1995 and calculated mortality rates, hospitalization days and direct costs of hospitalization. The data were obtained from the hospital discharge statistics for all general hospitals and for all hospitals of the General Austrian Accident Insurance. To calculate the portion of hip fractures attributable to osteoporosis in a given age-group, a basic, non-osteoporotic incidence of hip fractures was determined for ages 20-39, using gender-specific regression models. 11,379 patients with osteoporotic hip fractures underwent treatment in Austrian hospitals in 1995, accounting for 79 percent of all hip fracture patients treated. 82 percent of those were female, with the highest incidence among women aged 95 years and older with a rate of 3,000/100,000. For male patients the highest incidence was observed for the age-group of 90-94 years with 1,743/100,000. International comparisons indicate these incidence rates to be similar to those reported for the Swiss population. In 1995, 778 patients or 6.8 percent of all patients with osteoporotic hip fractures died during hospitalization. Hospital care of patients with osteoporotic hip fractures required an overall 250,268 bed-days with an age-group-specific length of stay between 8.5-27 days for female and 16-23 days for male patients. The total cost of hospital treatment of osteoporotic hip fractures in Austria was ATS 1,043,379,000 (US$ 103,509,800), with average costs per patient of ATS 91,700 (US$ 9,097). Due to the aging of the population in the years to come, an increase of osteoporotic hip fractures among individuals aged 50 years and older must be expected. The economic importance of this development and its impact on the health care system must be considered as significant.
本研究旨在调查奥地利骨质疏松性髋部骨折的流行病学及社会经济影响。我们确定了1995年在医院接受治疗的所有患者中骨质疏松性髋部骨折的年龄和性别特异性发病率，并计算了死亡率、住院天数及住院直接费用。数据取自所有综合医院及奥地利普通事故保险所有医院的出院统计资料。为计算特定年龄组中归因于骨质疏松症的髋部骨折比例，利用性别特异性回归模型确定了20 - 39岁髋部骨折的基本非骨质疏松性发病率。1995年，11379例骨质疏松性髋部骨折患者在奥地利医院接受治疗，占所有接受治疗的髋部骨折患者的79%。其中82%为女性，95岁及以上女性发病率最高，为3000/10万。男性患者中，90 - 94岁年龄组发病率最高，为1743/10万。国际比较表明，这些发病率与瑞士人群报告的发病率相似。1995年，778例患者（占所有骨质疏松性髋部骨折患者的6.8%）在住院期间死亡。骨质疏松性髋部骨折患者的住院护理总共需要250268个床日，女性患者特定年龄组的住院时间为8.5 - 27天，男性患者为16 - 23天。奥地利骨质疏松性髋部骨折的住院治疗总费用为1.043379亿奥地利先令（1035.098万美元），每位患者的平均费用为91700奥地利先令（9097美元）。由于未来人口老龄化，预计50岁及以上人群中骨质疏松性髋部骨折将会增加。必须认识到这一发展的经济重要性及其对医疗保健系统的影响重大。
