Mortalidade em pacientes com idade igual ou superior a 65 anos acometidos por fratura do fêmur proximal

Abstract

Hip fracture has increased in the last decades and has been considered one of the major causes of mortality and morbidity in elderly people. In most cases is an event with catastrophic consequences to elderly life with impairment in your physical, psychical and social welfare. Is often responsible for the permanent institutionalization of the elderly. Epidemiologic studies contribute to specify certain orthopedic and traumatologic injuries and it helps in the treatment and prevention of these injuries. These actions are essential to health promotion. In Latin America, there are few epidemiological studies on mortality associated with hip fracture in elderly. Aims to assess mortality one year after hip fracture and in-hospital mortality in elderly subjects who were treated at the Orthopaedics and Traumatology division of University Hospital of Santa Maria. Identifying risk factors for one year mortality in-hospital mortality in these subjects and determinate one year subjects survival. This is a prospective cohort study that evaluates one year mortality by Cox s Regression and in-hospital mortality by Logistic Regression. The survival time was evaluate by Kaplan Meier analyze. The mean age was 80.6±7.5(SD) years, 76.4% were female gender, 57.8% were transtrochanteric fracture and 44.9% had ASA grade I or II. One year mortality was 25.2% and in-hospital mortality was 12.5%. One year mortality predictor s were ASA (HR 1.922, 95% CI 1.150 3.211) and time to surgery (HR 1.049, 95% CI 1.012 1.087). Only ASA grade were risk factor for in-hospital mortality (OR 6.373, 95% CI 2.954 13.747). The survival time was 297.7±11.3 days. The mean time to surgery was 7.8±5.4 days. In our study for every day that the surgery was delayed the one year survival was shortened by 9 days. Improvements in public health that would decrease time to surgery could have an impact at the survival of these subjects. The ASA grade is a useful tool to evaluate the patient clinical status.
