Data were obtained from the Health Care Financing Administration and the Department of Veterans Affairs (formerly called Veterans Administration) on all hospital discharges among the elderly population from 1984 through 1987 and combined with census estimates to calculate incidence rates of hip fracture for the elderly population of the United States. Rates for White women were the highest, reaching 35.4 per 1,000 per year among 95 year-olds. Comparably, White men, Black women, and Black men experienced similar age-related increases in risk, although of less magnitude and relatively less rate of change, respectively.

    • "A rapidly ageing population in Western countries has lead to a predicted increase in worldwide incidence of hip fractures, up to 6.3 million in 2050 [3] [4] [5] [6]. Women make up at least 70% of all patients with a proximal femoral fracture according to the literature [7] [8]. Low preoperative haemoglobin levels in elderly patients have been shown to be associated with increased short-term morbidity and mortality after surgery, and still 24–33% of patients discharged following hospitalization for a hip fracture, die within 12 months after the incident [9] [10] [11] [12] [13] [14] [15].

    ABSTRACT: Hip fractures are a significant cause of mortality and morbidity in the elderly. This study investigated the relationship between initial haemoglobin (Hb) levels and a prognostic parameter for outcome in those patients. A total of 3595 consecutive patients with diagnosed hip fractures were included in our study (72.2% females). Anaemia was defined according to WHO criteria, with according subgroups mild, moderate and severe anaemia. Data collection was performed prospectively and statistical evaluation was performed retrospectively. Mean follow up in our study group was 11.2±0.3 months. The mean age of our study group was 78.5 years (SEM±0.2 years). To facilitate analysis, patients were divided in two groups: ≤84 years (60.1%) and ≥85 years (39.9%). Mortality <12 months was 12.2% (n=439). In our study population lower Hb levels ad admission were associated with a markedly elevated short-term mortality. In a multivariate logistic regression model adjusted for age and sex, mild anaemia at admission caused a 1.5 (CI: 1.1-1.9), moderate anaemia a 2.6 (95 CI: 2.0-3.4), and severe anaemia a 3.6 (CI: 1.8-6.9) fold increase in three months mortality compared to patients without anaemia. Total lymphocyte count (1.2±0) did not show any differences between the subgroups. Those findings in our study population with 3595 patients over a period of twenty years have proven that initial Hb levels are a useful and cost effective parameter to predict mortality in elderly patients with a hip fracture. This prognostic factor may help to increase the outcome of elderly patients with a hip fracture. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: Hip fracture represents the most dramatic expression of the disease, in terms of morbidity, medical cost and mortality. The incidence of hip fracture increases substantially with age. The purpose of this study was to evaluate the association between gender and geriatric rehabilitation outcome after traumatic hip fracture. Ninety-nine community-dwelling elderly patients (older than 65 years), 64 women and 35 men, who were admitted to geriatric rehabilitation after operated hip fracture were studied. We assessed the patients' clinical and demographic data, preoperative risk (ASA), type of fracture and orthopedic repair, pain intensity (VAS), cognitive (MMSE), mood (Zung IDS), and functional status (FIM) on admission and at the end of geriatric rehabilitation. Men had higher mean number of comorbid conditions at the time of the fracture. Men recovered more from depressed mood in comparison with women during the rehabilitation. Significant improvement in FIM motor subscore on discharge was found in both groups. The FIM motor subscore gain was higher in men (24.47) in comparison with women (19.22, p=0.036). Those differences were demonstrated in mean subscores of transfers (p=0.004), and locomotion (p=0.019). Women were more functionally dependent in locomotion, transfers and sphincter control. There were no differences between the groups by duration on rehabilitation stay. Recovery after hip fracture depends in large part on the pre-fracture health and functional ability of the patient. Gender differences in functional recovery may affect therapeutic and rehabilitative decision making. Functional recovery after traumatic hip fracture was better in men in comparison with women.

    • "In some studies that provided hip fracture incidence in women aged 85 and older [2] [11] [12] [20] [31] [35] [37] [38] [45], a slower increase in incidence is observed in the very elderly. "

    ABSTRACT: Hip fractures are the most devastating result of osteoporosis and are common worldwide. Based on an exponential increase in incidence with age, many studies in the 1990s forecasted an epidemic of hip fracture in women in the next 15 years which is not currently being observed. Despite the ageing of the populations, accurate description of hip fracture incidence in women aged 85 or older are scarce. All women aged 60 to 95, living in the Rhône-Alpes area of France, who were admitted to hospitals during 2001-2004 for treatment of hip fracture were selected from the French claims databases. An exponential model was tested to describe the increase in hip fracture incidence in women aged 60-84 and 60-95. The first model was used to predict annual hip fracture incidence in women aged 85-95 in the Rhône-Alpes area, in France and in Europe. An exponential model was adequate to describe the increase in incidence in women aged 60-84. Assuming an exponential increase in incidence in women aged 85-95, the predicted number of cases was overestimated by 70% in the Rhône-Alpes. In France and in Europe, the excess number of incident cases is believed to be respectively 16,000 and 85,965 a year. The age-specific incidence estimates an average risk although the individual risks are heterogeneous throughout the population. The slower increase in incidence after age 85 might not be related to a decreasing individual risk with age but rather might indicate that women at higher risk have already experienced hip fracture or have died. After age 85, women who are still at risk may represent a population with a lower risk of hip fracture. Models adapted to the elderly population should be developed to improve the accuracy of predictions and optimise the health care system.
