One-third of the world's hip fractures are said to occur in Asia, but there have been no validated studies of hip fracture rates in China. In 1988-1992 all 76 hospitals in Beijing reported 820 hip fracture admissions coded as ICD-9. Checking against original discharge logs, medical records, X-ray reports, operation notes and operating room logs of a random sample of Beijing hospitals to discover underestimated and misclassified cases. In order to estimate hip fracture treated outside hospitals, we also interviewed a random sample of 2113 women aged 50 and over with a 97% response rate in Beijing. Finally, we also surveyed 27 hospitals in the suburbs of Beijing, but have found that no Beijing residents had been treated for hip fracture outside the city. Based on the 1990 China census, age-standardized rates (per 100,000) of hip fractures in Beijing were 88 for women, 97 for men. From 1988 to 1992, the rates in Beijing increased 35% in women and 33% in men. This is the first validated population-based study on the rates of hip fractures in China that has confirmed the completeness and accuracy of reports of hip fracture cases and has estimated the degree of under-reporting of hospital discharge. Hip fracture rates in Beijing are among the lowest in the world but may rise rapidly.
据说世界上三分之一的髋部骨折发生在亚洲，但中国尚未有关于髋部骨折发生率的有效研究。1988年至1992年期间，北京所有76家医院报告了820例编码为ICD - 9的髋部骨折入院病例。通过核对北京医院随机样本的原始出院记录、病历、X光报告、手术记录和手术室日志，以发现被低估和错误分类的病例。为了估计在医院外接受治疗的髋部骨折情况，我们还随机采访了北京2113名50岁及以上的女性，应答率为97%。最后，我们还调查了北京郊区的27家医院，但发现没有北京居民在城外接受髋部骨折治疗。根据1990年中国人口普查，北京髋部骨折的年龄标准化发病率（每10万人）女性为88例，男性为97例。1988年至1992年期间，北京女性发病率上升了35%，男性上升了33%。这是中国第一项基于人群的关于髋部骨折发生率的有效研究，证实了髋部骨折病例报告的完整性和准确性，并估计了医院出院报告的漏报程度。北京的髋部骨折发生率在世界上处于最低水平，但可能会迅速上升。
