The hip fracture is the most devastating type of fracture both for the individual and the society, with nationwide studies and meta-analyses showing that about 25% of hip fracture patients die within a year of the event. In 2000, an estimated nine million fragility fractures occurred worldwide, with adverse consequences including chronic pain, disability, and premature death. However, short-term mortality has increased, which to some extent may partly be explained by the fact that LOS has decreased without being adapted to important risk factors. In conclusion, despite population aging, hip fracture incidence in Sweden has decreased over the last 20 years. From 1998 to 2017, LOS decreased by on average 4 days and was shorter in both male and female aged ≥ 90 years compared to those aged 80–89 ( P < 0.001 for comparisons). Strong risk factors ( P < 1 × 10 –25 for all) for 30-day mortality were older age, male sex, and shorter LOS. ![]() The results showed that the incidence of hip fracture decreased from 79.2 to 46.7/10,000 population in women and from 35.7 to 26.5/10,000 population in men. The outcomes were hip fracture incidence and 30-day mortality. The cohort included all individuals in Sweden aged ≥ 50 years with a first hip fracture diagnosis during 1998–2017 ( N = 313,761). In this nationwide cohort study, we investigated trends in hip fracture incidence, hospital length of stay (LOS), and 30-day mortality after admission in Sweden.
