MORTALITY AND RISK FACTORS AFTER A HIP FRACTURE: LONG-TERM FOLLOW-UP

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 July 1, 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.
