Abstract

Summary: There was an initial increase and a later decrease in hip fracture rates in Taiwan between 1996 and 2010 (457.9 to 390.0 fractures per 100,000 people per year). Mortality rates decreased but re-emerged later (2.26 to 1.91 deaths per 100 hip fracture admissions). The turning point for change in trends was 2003. Introduction: Fractures of the proximal femur remain a major cause of mortality and morbidity. We aimed to examine recent trends in hip fracture rates, in-hospital mortality rates, and length of hospital stay (LOS) due to hip fractures in people aged 55 and over in Taiwan. Methods: This is a time-trend study. We used data from the National Health Insurance Research Database between 1996 and 2010 in Taiwan. Insurants aged 55 and over were included. The outcome measures were age-adjusted hip fracture rates, age-adjusted in-hospital mortality rates, and LOS due to hip fractures. We classified hip fractures into femoral neck, trochanteric, and subtrochanteric fractures. Results: We identified 250,919 hospitalizations for hip fractures. The total number of hip fractures increased steadily from 12,479 to 19,841 cases. There was a trend towards initial increase and then later decrease in hip fracture rates (from 457.9 to 390.0 fractures per 100,000 people per year). LOS decreased by 46.5 % (17.53 to 9.38 days). By contrast, mortality rates for hip fractures decreased initially, but re-emerged later with a total decrement of 15.5 % (2.26 to 1.91 deaths per 100 hip fracture admissions). Women outnumbered men in all types of hip fractures, but men had higher in hospital mortality rates. LOS was similar between genders and among age groups. The turning point for change in trends was year 2003. Conclusions: While LOS shortened gradually since 1996, the absolute number of hip fractures in Taiwan continues to rise. There is still room for improvement in reducing mortality due to hip fractures.
