Hip fractures among older people in Iceland between 2008 and 2012

Abstract

Introduction: Hip fractures are a serious injury especially among older people, mainly caused by falls and women have a higher risk. The authors studied gender differences in hip fractures, marital status, waiting times for surgery and mortality in an older population.

Methods: Data was obtained for all 67 years and older admitted with hip fractures to an Emergency Department (ED) in Iceland 2008-2012. The associations of covariates with mortality were analyzed using multivariable logistic regression.

Results: The study included 1053 patients; covering 80% of hip fractures in Iceland during the study period, 72% were women. Men were more often married (51% vs. 23%) (P < 0.001). Average waiting time was men vs. women 21.5 h/18.9 h (p = 0.003). Mortality within 12 months was men 36% vs. women 21% (Odds Ratio (OR); 2.30, 95% Confidence Interval (CI); 1.66-3.18). Higher mortality rates were observed in older age-groups compared to 67-79 years old, i.e.80-89 years: OR 1.80 (95% CI 1.25-2.60) and 90-109 years: OR 4.52 (95% CI 2.91-7.01). Waiting time was not associated with 12-months mortality risk after adjustment.

Conclusion: Although women constitute the majority of elderly with hip fractures, men had higher mortality in our study. Further reserach that examine factors affecting gender difference will likey be of benefit and associated changes to the care already dleivered in the ED may improve mortality.
