ARTICLE HIGHLIGHTS
Research background

Hip fracture audit is increasing globally with 8 countries producing national reports annually and several countries currently piloting hip fracture audit schemes. Hip fracture audit has been shown to result in improvements in care and survival of older people. Short-term mortality rates (in-patient and 30-d) are published by the majority of national registries and there is evidence that short term mortality rates are decreasing. The 1-year mortality rate post hip fracture is currently recognized as approximately 30%. Recent longer-term (1-year) mortality information is lacking in the literature.

Research motivation

Our research group believes there may also be a changing trend (decreasing) in 1-year mortality post hip fracture. Knowledge of a more current, up-to-date figure will lead to a more informed discussion with family of those affected and optimization of care of this fragile cohort at hospital and national levels.

Research objectives

To determine the current 1-year mortality rate post hip fracture.

Research methods

Systematic literature review. The following keywords were used: “hip fracture”, “mortality”, “year”, “death”, “outcomes”, “registry”, “registries”, “database” and “databases” (PubMed and Google Scholar). The inclusion criteria were those studies published within the last 5 years (2013-2017), studies including a cohort >100 and those in the English language.

Research results

Data from 8 national registries and 36 countries (6 continents) were reviewed. Recently published 1-year mortality rates appear lower than traditional figures and suggest a downward trend.

Research conclusions

The previously quoted 1-year mortality rate of approximately 30% appears to be outdated. A figure of 22% is a more accurate, up-to-date figure for 1-year mortality rate post hip fracture.

Research perspectives

This research provides a more current, up-to-date figure for 1-year mortality rate post hip fracture.
