Mortality and risk factors after a hip fracture: long-term follow-up

Abstract

We conducted an ambidirectional cohort study to document mortality and risk factors in patients who suffered a hip fracture during 2006. Patients admitted for a hip fracture during 2006 were identified. The cohort was followed from the date of the fracture until death or 1/07/2009. One hundred and twenty four patients were admitted for a hip fracture during the period. Mean age was 79.4±8.7 years, 78.5% female. Mean follow-up was 2.33±0.089 years and 1.6% of the cases were lost. During the first year of the study, 16.2% of the patients died; a total of 25.8% died in the study period. Mortality differed between sex, and it was higher in men (30.8%) compared with women (24.5%). In multivariate analysis, risks factors of mortality included age (HR 1.07 per each additional year, p=0.027), diagnosis of dementia (HR 2.34: p<0.001), and coronary heart disease (HR 2.94, p<0.001). The event "hip fracture" diminished the survival of the population under study.
