Hip fractures among older people in Iceland between 2008 and 2012.

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.

Variations in elderly peoples' visits to the emergency departments in Iceland: A five-year population study.

INTRODUCTION: Elderly people visiting emergency departments (ED) are a non-homogenous group. Gender and other socio-demographic variations in emergency care might be present. However, gender-specific ED-data is scarce. METHODS: We retrieved retrospective data on all ED-visits, by 67years and older from 2008 to 2012, and calculated incidence of visits applying population registries. The relationship of age-categories, marital status, health and residence with outcomes were analyzed descriptively by Chi-square tests. Regression models were built to analyze gender-specific variations. RESULTS: Of the total ED-visits, 20% were from the elderly population (n=66,141), at a mean 3.1 visits per individual. Men (n=30.269) had higher incidence of visits in all age-categories. They were mostly married (69%) and women widowed (43%), although the incidence of partnered visitors underrepresented population-data while widowed and single living overrepresented. Women had more often co-morbidities, their most common causes of visits were musculoskeletal (20%) and men circulatory causes (14%). Men were more likely to be admitted (OR: 1.23; 95% CI 1.16-1.30) and had more unplanned ED-revisits (HR: 1.20; 95% CI 1.06-1.35) within 30 days. DISCUSSION: Elderly men visiting the ED were more often married than women. Gender differences were found in causes of visits and outcomes. In clinical practice, gender may be considered when identifying risk and planning adequate care related elderly ED-visits.
