Abstract
BACKGROUND

Traditionally, the mortality rate at 1-year post hip fracture was quoted as approximately 30% of all hip fractures. There have been recent improvements in hip fracture care in the main driven by national hip fracture registries with reductions in 30-d mortality rates reported.

AIM

To address recent 1-year post hip fracture mortality rates in the literature.

METHODS

Systematic literature review, national hip fracture registries/databases, local studies on hip fracture mortality, 5 years limitation (2013-2017), cohorts > 100, studies in English. Outcome measure: Mortality rate at 1-year post hip fracture.

RESULTS

Recent 1-year mortality rates were reviewed using the literature from 8 National Registries and 36 different countries. Recently published 1-year mortality rates appear lower than traditional figures and may represent a downward trend.

CONCLUSION

There appears to be a consistent worldwide reduction in mortality at 1-year post hip fracture compared to previously published research. Globally, those which suffer hip fractures may currently be benefiting from the results of approximately 30 years of national registries, rigorous audit processes and international collaboration. The previously quoted mortality rates of 10% at 1-mo and 30% at 1-year may be outdated.

Keywords: Hip fracture; Mortality; Registries; Databases

Core tip: This review reports a global downward trend in 1-year mortality rate post hip fracture. The results of this study suggest that the previously reported 1-year mortality rate of 30% is out-dated and a figure of 22% is a more accurate, up-to-date estimation of 1-year mortality rate post hip fracture.
