QUINTAS, Carmen Mª Gándara et al. Survival after hip fracture in postmenopausal women. Rev Port Med Geral Fam [online]. 2013, vol.29, n.6, pp.378-384. ISSN 2182-5173.

Aim: To study survival after low energy hip fracture in postmenopausal women and the risk factors associated with mortality. Design: Retrospective cohort study. Location: Primary care and hospital care in the province of Ourense (Spain). Participants: All women with hip fracture in 2006 and 2007, with follow-up until July 2011. Methods: We determined the date of fracture, the age at the time of fracture, residence (rural/urban), comorbidity (dementia, heart disease, cerebrovascular disease, diabetes mellitus, COPD, neoplastic disease), anaesthetic risk (ASA grade), surgical delay, previous fracture, and date of death or survival to date or until the end of the study period. Kaplan-Meier analysis was used to estimate the probability of survival. Cox regression analysis was used to assess risk factors. Results: We included 626 cases in the study. The mean age of patients was 84.0 years (SD 8.1). 339 patients (54.2%) died during the follow-up period. 98 women (28.9%) died in the first 3 months after fracture. Mean survival was 41,9 months (SE 1,1), with a median of 47,7 months (SE 3,2). The survival rate at 12 months after fracture was 79.2%, 68.1% at 24 months, and 57.0% at 36 months. There was a relationship between decreased survival and older age at the time of fracture, a greater number of comorbidities, and rural residence. Higher survival rates were associated with previous fracture and surgical stabilization. Conclusions: Survival after hip fracture in this population is similar to that reported in the literature. Mortality is associated primarily with comorbidity and is higher in the first months after a fracture.
