Excess mortality following a first and subsequent osteoporotic fracture: a Danish nationwide register-based cohort study on the mediating effects of comorbidities. RMD Open 2023; 9:e003524. [PMID: 38030232 PMCID: PMC10689412 DOI: 10.1136/rmdopen-2023-003524] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Accepted: 11/05/2023] [Indexed: 12/01/2023] Open
Abstract
OBJECTIVES This study aimed to examine the risk of mortality following incident and subsequent osteoporotic fractures, the effect of different fracture type combinations, and the mediating role of postfracture morbidity in a Danish population. METHODS We used the National Patient Registry to identify patients ≥60 years with incident major osteoporotic fracture of the hip, vertebrae, wrist or humerus between 2013 and 2018, and controls matched 1:10 on age and sex. Possible mediators were identified using International Classification of Diseases, 10th Revision codes registered in the 6 months following index fracture. HRs were estimated using Cox regression analyses with 95% CIs. The effect of possible mediators was estimated using mediation analyses. RESULTS The study included 106 303 patients and 1 062 988 controls. Mortality following index fracture was highest in the month following hip fractures (HR 10.98 (95% CI 10.23 to 11.79) in women and HR 16.40 (95% CI 15.00 to 17.93) in men). Subsequent hip fractures resulted in the highest HRs for all fracture type combinations. In women, the highest HR was observed in patients with index wrist/subsequent hip fractures (HR 2.43 (95% CI 2.12 to 2.78)). In men, the highest HR was observed in patients with index humerus/subsequent hip fractures (HR 2.69 (95% CI 2.04 to 3.54)). Pneumonia mediated the largest proportion of mortality, but dehydration, urinary tract infection and sepsis were also important factors. CONCLUSIONS The highest mortality risk was found in the month immediately following both index and subsequent fracture. The combination of index and subsequent fractures at different skeletal sites had a substantial impact on the risk of mortality. Postfracture morbidities were found mediate the association.

Abstract
UNLABELLED Fall prevention programs have shown inconclusive results concerning hip fracture reduction. We found that fallers with poor health, low societal participation, and use of psychotropics/painkillers had a threefold to fivefold increased hip fracture risk compared to non-fallers without these risk factors. This may help target fall prevention towards high-risk individuals. INTRODUCTION To investigate whether self-reported information on health, societal participation, and drug use in older people, easily obtainable by health care providers, contribute to predict future hip fracture beyond self-reported falls. METHODS We used data from 3801 women and 6439 men aged 70-79 years participating in population-based studies in five counties in Norway 2000-2003. Height and weight were measured. Socioeconomic status, lifestyle, health status, and history of falling were self-reported through questionnaires. Falls last year were dichotomized into one or more versus no falls. Hip fractures were identified by linkage to hospital data with follow-up through 2013. Hazard ratios (HR) with 95% confidence intervals (95% CI) for hip fracture by combinations of risk factors with history of falling were estimated using Cox proportional hazards regression. RESULTS More women (32.4%) than men (27.7%) reported one or more falls during the previous year, and 17.9% of women (n = 682) and 8.9% of men (n = 572) suffered a hip fracture during median 11.6 years of follow-up. Poor health, low societal participation, and use of psychotropics/analgesics among fallers were strong predictors of hip fracture. The presence of all three risk factors and history of falling was associated with HR 2.92 (95% CI 2.10-4.05) for hip fracture in women and HR 4.60 (95% CI 2.71-7.81) in men compared to non-fallers without these factors. CONCLUSION Our study indicates that self-assessment of health, information about activities outside home, and drug use among fallers far better identify high risk of hip fracture in older people than information about falls alone.

Abstract
The aim of this study is to investigate the impact of bisphosphonate treatment on the prognosis of patients with initial hip fracture. Patients aged fifty years and older with initial hip fracture were identified from the Taiwan National Health Insurance Research Database between 2002 and 2011. A multi-state model was established to evaluate the transition between "first to second hip fracture", "first hip fracture to death", and "second hip fracture to death". Transition probability and cumulative hazards were used to compare the prognosis of initial hip fracture in a bisphosphonate treated cohort versus non-treated cohort. In addition, Deyo-Charlson comorbidities, both vertebral and non-vertebral fractures, and cataracts were also included for analysis. After 10-year follow-up, there is decreased cumulative transition probability for both second hip fracture and mortality after both first and second hip fracture in the bisphosphonate treated cohort. Multivariable, transition-specific time-dependent Cox model revealed that bisphosphonate treatment significantly reduced risk for second hip fracture in the first 5 years of the treatment (HR 0.88; 95% CI 0.79-0.99; P: 0.034), first hip fracture mortality (HR 0.88; 95% CI 0.83-0.93; P < 0.001), and second hip fracture mortality in the first 2 years of the treatment (HR 0.78; 95% CI 0.65-0.95; P = 0.011). Female sex, both vertebral and non-vertebral fractures, cataracts, dementia in the first 2 years, and DM with complication were all significantly associated with risk of a second hip fracture. Cerebrovascular disease and hemiplegia comorbidities had less risk of a second hip fracture. The risk of mortality after both first and second hip fracture was significantly associated with congestive heart failure, renal disease, myocardial infarction, and moderate to severe liver disease. Our study demonstrated that bisphosphonate treatment and strict management of comorbidities after the initial hip fracture significantly decrease the risk for a second hip fracture and mortality.

[PMID: 34017617 PMCID: PMC8114282 DOI: 10.1177/21514593211015103] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 04/10/2021] [Accepted: 04/12/2021] [Indexed: 12/04/2022] Open
Abstract
Introduction: Hip fractures predominantly occur in the geriatric population and results in increased physical inactivity and reduced independency, largely influenced by a downward spiral of ambulatory capacity, related to loss of skeletal muscle strength and postural stability. Thus, effective postoperative treatment, targeting improvements in muscle strength, is sought after. Materials & Methods: Twenty-one hip fracture patients (>65 yr) were randomized to 8 weeks of either conventional physiotherapy control group (CG), or leg press and hip abduction maximal strength training (MST) 3 times per week. MST was performed applying heavy loads (85-90% of 1 repetition maximum; 1RM) and 4-5 repetitions in 4 sets. Maximal strength (bi- and unilateral 1RM), postural stability (unipedal stance test; UPS), and DEXA-scan bone mineral content/ density (BMC/BMD) were measured before and after the 8-week rehabilitation. Results: Both MST and conventional physiotherapy improved bilateral leg press 1RM by 41 ± 27 kg and 29 ± 17 kg, respectively (both p < 0.01), while unilateral leg press 1RM only increased after MST (within group and between groups difference: both p < 0.05). MST also resulted in an increase in abduction 1RM in both the fractured (5 kg, 95%CI: 2-7; p < 0.01) and healthy limb (6 kg, 95%CI: 3-9; p < 0.01), while no such improvement was apparent in the CG (between groups difference: p < 0.01). Finally, MST improved UPS of the fractured limb (p < 0.05). No differences were observed in BMC or BMD following the 8 weeks. Discussion: Early postoperative MST improved lower extremities maximal muscle strength more than conventional physiotherapy and was accompanied by improvements in postural stability. Conclusion: Implementing MST in early rehabilitation after hip fracture surgery should be considered as a relevant treatment to curtail the downward spiral of reduced ambulatory capacity typical for this patient group, possibly reducing the risk of recuring falls and excess mortality.

Abstract
Purpose The 30-day mortality rate after hip fracture surgery has been considered as an indirect indicator of the quality of care. The aim of this work is to analyse preoperative and postoperative factors potentially related to early 30-day mortality in patients over 65 undergoing hip fracture surgery. Methods Prospective cohort study including all consecutive primary hip fracture patients over 65 admitted to Trauma and Orthopaedics department from January 1, 2018 to December 31, 2019. Bed-ridden, non- surgically treated patients, and high energy trauma or tumoral aetiology fractures were excluded. A total of 943 patients were eligible (attrition rate: 2.1%). Follow-up included 30-days after discharge. We noted the 30-day mortality after hip fracture surgery, analysing 130 potentially related variables including biodemographic, fracture-related, preoperative, and postoperative clinical factors. Qualitative variables were assessed by χ2, and quantitative variables by non-parametric tests. Odds ratio determined by binary logistic regression. We selected preventable candidate variables for multivariate risk assessment by logistic regression. Results A total of 923 patients were enrolled (mean age 86.22±6.8, 72.9% women). The 30-day mortality rate was 6.0%. We noted significant increased mortality on men (OR = 2.381[1.371–4.136], p = 0.002), ageing patients (ORyear = 1.073[1.025–1.122], p = 0.002), and longer time to surgery (ORday = 1.183[1.039–1146], p<0.001), on other 20 preoperative clinical variables, like lymphopenia (lymphocyte count <103/μl, OR = 1.842[1.063–3.191], p = 0.029), hypoalbuminemia (≤3.5g/dl, OR = 2.474[1.316–4.643], p = 0.005), and oral anticoagulant intake (OR = 2.499[1.415–4.415], p = 0.002), and on 25 postoperative clinical variables, like arrhythmia (OR = 13.937[6.263–31.017], p<0.001), respiratory insufficiency (OR = 7.002[3.947–12.419], p<0.001), hyperkalaemia (OR = 10.378[3.909–27.555], p<0.001), nutritional supply requirement (OR = 3.576[1.894–6.752], p = 0.021), or early arthroplasty dislocation (OR = 6.557[1.206–35.640], p = 0.029). We developed a predictive model for early mortality after hip fracture surgery based on postoperative factors with 96.0% sensitivity and 60.7% specificity (AUC = 0.863). Conclusion We revealed that not only preoperative, but also postoperative factors have a great impact after hip fracture surgery. The influence of post-operative factors on 30-day mortality has a logical basis, albeit so far they have not been identified or quantified before. Our results provide an advantageous picture of the 30-day mortality after hip fracture surgery.

Abstract
BACKGROUND The incidence rate of hip fractures seems to be declining in many western countries. However, due to the ageing of the population, the number of fractures may still be on the rise. No papers so far have quantified the future burden of hip fractures in terms of both health loss (as measured in disability adjusted life years DALY) and costs. The purpose of this paper is to assess the future health and economic burden of hip fractures. METHODS We collected population projections from Statistics Norway up until the year 2040. The medium projection was used for the base case analysis. Fracture rates for 2008 were estimated based on information from the Norwegian Epidemiologic Osteoporosis Studies (NOREPOS) hip fracture database (NORHip), which includes information about all hip fractures in Norway. Future fracture rate was assumed to decline by 0.7% per year in the base case. We used the same assumptions as the global burden of disease project on years of remaining life and disability weights. Cost of hip fracture was based on the published literature. In sensitivity analyses, we assessed the impact of changing underlying assumptions on demographic change, development in hip fracture rate, assumed life expectancy and choice of disability weights. RESULTS Assuming a medium population growth and a continued decline in fracture rate, our estimates indicate that health lost to hip fractures will approximately double, from 32,850 DALYs in 2020 to 60,555 in 2040. Over the same period, costs are estimated to increase by 65%. Sensitivity analyses indicate that estimates are highly sensitive to assumptions on both population growth, fracture rate development, disability weights and assumed life expectancy. CONCLUSION The burden of hip fractures in terms of DALYs lost and cost incurred is likely to increase even if the fracture rate continues to decline.

Abstract
UNLABELLED Less is known about the impact of non-hip non-vertebral fractures (NHNV) on early death. This study demonstrated increased risk of dying following hip and NHNV fractures which was further increased by a subsequent fracture. This highlights the importance of early intervention to prevent both initial and subsequent fractures and improve survival. INTRODUCTION Osteoporotic fractures are a major health concern. Limited evidence exists on their impact on mortality in ageing populations. This study examined the contribution of initial fracture type and subsequent fracture on mortality in a Norwegian population that has one of the highest rates of fractures. METHODS The Tromsø Study is a prospective population-based cohort in Norway. Women and men aged 50+ years were followed from 1994 to 2010. All incident hip and non-hip non-vertebral (NHNV) fractures were registered. NHNV fractures were classified as either proximal or distal. Information on self-reported co-morbidities, lifestyle factors, general health and education level was collected. Multivariable Cox models were used to quantify mortality risk with incident and subsequent fractures analysed as time-dependent variables. RESULTS Of 5214 women and 4620 men, 1549 (30%) and 504 (11%) sustained a fracture, followed by 589 (38%) and 254 (51%) deaths over 10,523 and 2821 person-years, respectively. There were 403 (26%) subsequent fractures in women and 68 (13%) in men. Hip fracture was associated with a two-fold increase in mortality risk (HR 2.05, 95% CI 1.73-2.42 in women and 2.49, 95% CI 2.00-3.11 in men). Proximal NHNV fractures were associated with 49% and 81% increased mortality risk in women and men (HR 1.49, 95% CI 1.21-1.84 and 1.81, 95% CI 1.37-2.41), respectively. Distal NHNV fractures were not associated with mortality. Subsequent fracture was associated with 89% and 77% increased mortality risk in women and men (HR 1.89, 95% CI 1.52-2.35 and 1.77, 95% CI 1.16-2.71), respectively. CONCLUSION Hip, proximal NHNV and subsequent fractures were significantly associated with increased mortality risk in the elderly, highlighting the importance of early intervention.

Abstract
Background Hip fracture surgery (HFS) is often associated with perioperative blood loss, and it frequently necessitates transfusion. However, the hemoglobin (Hb) threshold for transfusion remains controversial in hip fracture patients. We evaluated the usefulness of the restrictive strategy and preoperative intravenous iron supplementation in HFS. Methods We retrospectively reviewed the medical records of 1,634 patients (> 60 years of age) who underwent HFS between May 2003 and June 2014 and were followed up for 1 year or more after surgery. We used the liberal transfusion strategy until May 2009 to determine the transfusion threshold; afterwards, we switched to the restrictive transfusion strategy. Patients with the restrictive transfusion strategy (restrictive group) received intravenous iron supplementation before surgery. We compared the transfusion rate, morbidity, and mortality of the restrictive group with those of the patients with the liberal transfusion strategy (liberal group). Results Preoperative intravenous iron supplementation was not associated with any adverse reactions. The transfusion rate was 65.3% (506/775) in the liberal group and 48.2% (414/859) in the restrictive group (p < 0.001). The mean hospital stay was shorter in the restrictive group (21.5 vs. 28.8 days, p < 0.001). There was no significant difference in the postoperative medical complications including myocardial infarction and cerebrovascular event. Mortality at postoperative 30, 60, and 90 days was similar between the two groups. Conclusions Our blood management protocol involving restrictive strategy combined with preoperative intravenous iron supplementation appears to be effective and safe in HFS of elderly patients.

Abstract
Osteoporosis is a major health problem in terms of fracture probability and disability. The aim of this ecological study is to identify the temporal trends in osteoporosis mortality in Spain from 1999 to 2015. Data on the Spanish population and number of deaths due to osteoporosis were obtained from the Spanish National Institute for Statistics. Age-adjusted mortality rates were estimated. Join point regression was used to identify the years when changes in mortality s and annual percentage change in mortality rates took place. Women presented a greater mortality rate decrease (p < 0.001), though this mortality difference by sex was reduced by half at the end of the period. The higher the age, the faster the mortality rate declined in women, while no clear pattern could be identified in men. In women, significant changes in trends were identified in three age groups (50-54, 60-64 and 80-84 years old). A sustained decrease in osteoporosis-associated mortality was found in women aged 75-79 and ≥85 years and men aged 60-64. In conclusion, mortality caused by osteoporosis in Spain is decreasing faster in the older age ranges especially in women.

Abstract
Aims The aim of this study was to compare the rate of mortality and causes of death in Korean patients who undergo surgery for a fracture of the hip, up to 11 years after the injury, with a control group from the general population. Materials and Methods National cohort data from Korean Health Insurance Review and Assessment Service – National Sample Cohort were used. A ratio of 1:4 matched patients with a fracture who underwent surgery (3383, fracture group) between 2003 and 2012, and controls (13 532) were included. The matches were processed for age, gender, income, and region of residence. We also undertook analyses of subgroups according to age and gender. The mean follow-up was 4.45 years (1 to 11). Results The prevalence of hypertension, diabetes, and stroke was significantly higher in the fracture group and dyslipidemia in the controls. Both crude and adjusted hazard ratios (HR) for the rate of mortality in the fracture group were > 2 (crude HR 2.03, 95% confidence interval (CI) 1.91 to 2.17, p < 0.001; adjusted HR 2.07, 95% CI 1.94 to 2.21, p < 0.001). The HRs were also > 2 for both men and women, and for both those aged ≥ 50 years and < 50 years. However, for those aged < 50 years, they were insignificant. The rates of mortality due to all 11 major causes of death classified following Korean standard classification of diseases were significantly higher in the fracture group compared with the control group, except those in the mental and behavioral disorders category. Conclusion The rate of mortality in the fracture group was significantly higher than in the control group up to 11 years after the surgery. The rate of death due to almost every major cause was significantly higher in the fracture group compared with the control group. Cite this article: Bone Joint J 2018;100-B:436–42.

Abstract
PURPOSE OF REVIEW Bone remodeling is a diverse field of study with many direct clinical applications; past studies have implicated epigenetic alterations as key factors of both normal bone tissue development and function and diseases of pathologic bone remodeling. The purpose of this article is to review the most important recent advances that link epigenetic changes to the bone remodeling field. RECENT FINDINGS Epigenetics describes three major phenomena: DNA modification via methylation, histone side chain modifications, and short non-coding RNA sequences which work in concert to regulate gene transcription in a heritable fashion. Recent findings include the role of DNA methylation changes of Wnt, RANK/RANKL, and other key signaling pathways, epigenetic regulation of osteoblast and osteoclast differentiation, and others. Although much work has been done, much is still unknown. Future epigenome-wide studies should focus on extending the tissue coverage, integrating multiple epigenetic analyses with transcriptome data, and working to uncover epigenetic changes linked with early events in aberrant bone remodeling.

The impact of comorbidities on hip fracture mortality: a retrospective population-based cohort study. Arch Osteoporos 2017; 12:76.

Abstract
UNLABELLED The impact of comorbidities on hip fracture-related excess mortality was assessed in a population-based age- and sex-matched cohort over 10 years. On average, only 1 out of 12 excess deaths over 10 years was related to pre-fracture life-threatening comorbidities. The presence of life-threatening comorbidities increased the excess risk of death after hip fracture. PURPOSE This work aimed to estimate the impact of pre-fracture comorbidities on the 10-year excess risk of all-cause death after hip fracture among Estonian men and women ≥ 50 years of age. METHODS Retrospective, population-based 10-year study of people aged ≥ 50 in two cohorts: those with a hip fracture and an age- and sex-matched random sample from the national health insurance fund for comparison. RESULTS We found that hip fracture was a strong independent risk factor for death. Upon adjustment for Charlson Comorbidities Index (CCI) score, the impact of life-threatening comorbidities on average hip fracture-related excess mortality was modest: only 8% of excess deaths over 10 years were related to comorbidities. Upon stratification by CCI groups, the excess risk of patients in CCI groups ≥ 3 and 1-2 exceeded that in the CCI 0 group over 5-7 years, indicating that in patients with life-threatening comorbidities, a hip fracture accelerates the chain of lethal events and brings deaths from other conditions forward. The impact of comorbidities was age- and time-dependent: in younger hip fracture patients, the comorbidities almost doubled the excess risk from a fracture in 10 years; in older patients, the effect was shorter and modest. CONCLUSIONS The presence of pre-fracture comorbidities increases the risk of excess death in hip fracture patients, but the comorbidity impact on aggregated excess mortality is modest.

Abstract
BACKGROUND No studies have estimated disability-adjusted life-years (DALYs) lost due to hip fractures using real-life follow-up cohort data. We aimed to quantify the burden of disease due to incident hip fracture using DALYs in prospective cohorts in the CHANCES consortium, and to calculate population attributable fractions based on DALYs for specific risk factors. METHODS We used data from six cohorts of participants aged 50 years or older at recruitment to calculate DALYs. We applied disability weights proposed by the National Osteoporosis Foundation and did a series of sensitivity analyses to examine the robustness of DALY estimates. We calculated population attributable fractions for smoking, body-mass index (BMI), physical activity, alcohol intake, type 2 diabetes and parity, use of hormone replacement therapy, and oral contraceptives in women. We calculated summary risk estimates across cohorts with pooled analysis and random-effects meta-analysis methods. FINDINGS 223 880 men and women were followed up for a mean of 13 years (SD 6). 7724 (3·5%) participants developed an incident hip fracture, of whom 413 (5·3%) died as a result. 5964 DALYs (27 per 1000 individuals) were lost due to hip fractures, 1230 (20·6%) of which were in the group aged 75-79 years. 4150 (69·6%) DALYs were attributed to disability. Current smoking was the risk factor responsible for the greatest hip fracture burden (7·5%, 95% CI 5·2-9·7) followed by physical inactivity (5·5%, 2·1-8·5), history of diabetes (2·8%, 2·1-4·0), and low to average BMI (2·0%, 1·4-2·7), whereas low alcohol consumption (0·01-2·5 g per day) and high BMI had a protective effect. INTERPRETATION Hip fracture can lead to a substantial loss of healthy life-years in elderly people. National public health policies should be strengthened to reduce hip fracture incidence and mortality. Primary prevention measures should be strengthened to prevent falls, and reduce smoking and a sedentary lifestyle. FUNDING European Community's Seventh Framework Programme.

Abstract
Background Osteoporotic hip fractures are associated with high mortality and morbidity in people of advanced age; however, few studies have investigated the complication rates in nonagenarians. In this study, we applied a competing risk analysis to estimate the mortality, readmission, and reoperation rates after surgery for hip fracture among nonagenarians. Methods A total of 11,184 nonagenarians (aged ≥ 90) who received surgery for hip fracture during the period 1 January 1997 and 31 December 2010 were selected from Taiwan’s National Health Insurance (NHI) database. Nonagenarians were followed up until the end of 2012, death, or the date they left the NHI program. Cumulative mortality was estimated using the Kaplan-Meier analysis and risk factors for mortality were investigated using a Cox proportional hazards model. Competing risk analysis was used to estimate cumulative incidence rates and to assess the risk factors for reoperation and readmission. Results The mortality rates were 29.5% at 1 year, 45.0% at 2 years and 78.1% at 5 years. The cumulative incidence rates of reoperation were 7.3% at 1 year, 9.2% at 2 years and 11.6% at 5 years whereas those of readmission were 18.9% at 1 month and 24.1% at 3 months. Significant risk factors for death included age, male gender, trochanteric fracture, and higher Charlson comorbidity index (CCI) whereas those for reoperation were age, cervical fracture and higher CCI. Furthermore, age, male gender, and higher CCI were risk factors for readmission. Conclusions The overall 2-years mortality rate among nonagenarians in Taiwan was around 45%, the 2-years reoperation rate was around 9% and the 90-days medical complication rate was around 24%. High complication rates are associated with increased risk for death. Postoperative care to prevent medical complications is likely the most effective strategy to reduce mortality rates among nonagenarians with hip fracture.

Abstract
PURPOSE Conflicting findings were observed from clinical trials and observational studies evaluating the association between the use of statins and the risk of fracture. A case-control study nested into a cohort of elderly patients on treatment with statins for cardiovascular secondary prevention was performed on this issue. METHODS The cohort was formed by 13 875 individuals aged ≥65 years from several Italian health units receiving statins after hospital discharge for cardiovascular outcomes. From this cohort, 964 patients who experienced fracture were identified (i.e., cases). Up to five controls were randomly selected for each case from the underlying cohort. Conditional logistic regression was used to model the risk of fracture associated with adherence to statins, which was measured from the proportion of days covered (PDC) by treatment. A set of sensitivity analyses was performed in order to account for sources of systematic uncertainty. RESULTS Compared with patients with low adherence (PDC ≤ 40%), those on intermediate (PDC 41-80%) and high (PDC > 80%) adherence exhibited a risk reduction of 21% (95% confidence interval 6% to 23%) and 25% (7% to 40%). Similar effects were observed among patients younger and older than 80 years, as well as among men, while there was no evidence that adherence to statins affected the risk of fracture among women. Sensitivity analyses revealed that the associations were consistent and robust. CONCLUSIONS Use of statins for secondary cardiovascular prevention is associated with fracture risk reduction in elderly people. Further studies are required to better clarify the statin-fracture association in postmenopausal women. Copyright © 2017 John Wiley & Sons, Ltd.

Osteoporos Int 2017; 28:881-887.

Abstract
UNLABELLED Self-perceived health, smoking, and body mass index measured years before the hip fracture predicted excess post-hip fracture mortality, and even hip fracture patients with the most favorable levels of these risk factors had higher mortality than subjects who did not fracture. INTRODUCTION This study aimed to investigate the impact of pre-fracture self-perceived health, smoking, and body mass index (BMI) on excess post-hip fracture mortality using matched peers without hip fracture as reference. METHODS The study was based on the Cohort of Norway (CONOR) consisting of 10 regional health studies (1994-2003) and the NOREPOS hip fracture database (1994-2008). A matched cohort design was used to compare survival between hip fracture patients and subjects without fracture (matched on gender, age at participation in CONOR, and study site). Subjects aged ≥60 years were included. Hazard ratios were estimated using stratified Cox regression. Age-standardized mortality was also calculated. RESULTS Overall, hip fracture patients (N = 3177) had a 2.26-fold (95 % CI 2.13, 2.40) increased mortality compared to matched subjects (N = 20,282). The highest excess mortality was found in hip fracture patients reporting poor health (HR 4.08, 95 % CI 3.17, 5.26) and daily smoking (HR 3.25, 95 % CI 2.89, 3.66) and in patients with BMI <18.5 (HR 3.07, 95 % CI 2.11, 4.47) prior to the fracture. However, excess mortality was also observed in hip fracture patients in all other categories of BMI, self-perceived health, and smoking. CONCLUSIONS Information on self-perceived health, smoking, and BMI collected years before hip fracture predicted excess post-hip fracture mortality, and even hip fracture patients with the most favorable levels of these risk factors had higher mortality than the matched subjects who did not fracture. This suggests that both pre-fracture health status and factors related to the hip fracture itself might affect post-hip fracture mortality.

Abstract
UNLABELLED Frail elderly individuals have elevated risks of both fracture and mortality. We found that incident fractures were associated with an increased risk of death even after adjusting for pre-fracture frailty status as represented by physical performance tests and laboratory tests for common geriatric diseases in community-dwelling elderly Japanese men. INTRODUCTION While fractures reportedly increase the risk of mortality, frailty may complicate this association, generating a false-positive result. We evaluated this association after adjusting for pre-fracture levels of frailty. METHODS We examined 1998 community-dwelling ambulatory men aged ≥65 years at baseline in the Fujiwara-kyo Osteoporosis Risk in Men Study for frailty status as represented by activities of daily living (ADL), physical performance tests (grip strength, one-foot standing balance with eyes open, timed 10-m walk), and laboratory sera tests. Participants were then followed for 5 years for incident clinical fractures and death. Effects of incident fracture on death were determined by Cox proportional hazards model with the first fracture during follow-up as a time-dependent predictor and with frailty status indices as covariates. RESULTS We identified 111 fractures in 99 men and 138 deaths during the follow-up period (median follow-up, 4.5 years). Participants with incident fractures did not have significantly worse frailty statuses, but did show a significantly higher cumulative mortality rate than those without fractures (p = 0.0047). Age-adjusted hazard ratio (HR) of death for incident fracture was 3.57 (95 % confidence interval: 2.05, 6.24). When adjusted for physical performance, this decreased to 2.77 (1.51, 5.06), but remained significant. The HR showed no significant change when adjusted for laboratory test results (3.96 (2.26, 6.94)). Exclusion of deaths within the first 24 months of follow-up did not alter these results. CONCLUSION Incident clinical fracture was associated with an elevated risk of death independently of pre-fracture levels of frailty in community-dwelling elderly men.

Abstract
BACKGROUND Hip fractures are associated with diminished quality of life and survival especially amongst the elderly. OBJECTIVE All-cause mortality after hip fracture was investigated to assess its magnitude. METHODS A total of 122 808 participants from eight cohorts in Europe and the USA were followed up for a mean of 12.6 years, accumulating 4273 incident hip fractures and 27 999 deaths. Incident hip fractures were assessed through telephone interviews/questionnaires or national inpatient/fracture registries, and causes of death were verified with death certificates. Cox proportional hazards models and the time-dependent variable methodology were used to assess the association between hip fracture and mortality and its magnitude at different time intervals after the injury in each cohort. We obtained the effect estimates through a random-effects meta-analysis. RESULTS Hip fracture was positively associated with increased all-cause mortality; the hazard ratio (HR) in the fully adjusted model was 2.12, 95% confidence interval (CI) 1.76-2.57, after adjusting for potential confounders. This association was stronger amongst men [HR: 2.39, 95% CI: 1.72-3.31] than amongst women [HR: 1.92, 95% CI: 1.54-2.39], although this difference was not significant. Mortality was higher during the first year after the hip fracture [HR: 2.78, 95% CI: 2.12-3.64], but it remained elevated without major fluctuations after longer time since hip fracture [HR (95% CI): 1.89 (1.50-2.37) after 1-4 years; 2.15 (1.81-2.55) after 4-8 years; 1.79 (1.57-2.05) after 8 or more years]. CONCLUSION In this large population-based sample of older persons across eight cohorts, hip fracture was associated with excess short- and long-term all-cause mortality in both sexes.

Abstract
UNLABELLED Men and women with hip fracture have higher short-term mortality. This study investigated mortality risk over two decades post-fracture; excess mortality remained high in women up to 10 years and in men up to 20 years. Cardiovascular disease (CVD) and pneumonia were leading causes of death with a long-term doubling of risk. INTRODUCTION Hip fractures are associated with increased mortality, particularly short term. In this study with a two-decade follow-up, we examined mortality and cause of death compared to the background population. METHODS We followed 1013 hip fracture patients and 2026 matched community controls for 22 years. Mortality, excess mortality, and cause of death were analyzed and stratified for age and sex. Hazard ratio (HR) was estimated by Cox regression. A competing risk model was fitted to estimate HR for common causes of death (CVD, cancer, pneumonia) in the short and long term (>1 year). RESULTS For both sexes and at all ages, mortality was higher in hip fracture patients across the observation period with men losing most life years (p < 0.001). Mortality risk was higher for up to 15 years (women (risk ratio (RR) 1.9 [95 % confidence interval (CI) 1.7-2.1]); men (RR 2.8 [2.2-3.5])) and until end of follow-up ((RR 1.8 [1.6-2.0]); (RR 2.7 [2.1-3.3])). Excess mortality by time intervals, censored for the first year, was evident in women (<80 years, up to 10 years; >80 years, for 5 years) and in men <80 years throughout. CVD and pneumonia were predominant causes of death in men and women with an associated higher risk in all age groups. Pneumonia caused excess mortality in men over the entire observation period. CONCLUSION In a remaining lifetime perspective, all-cause and excess mortality after hip fracture was higher even over two decades of follow-up. CVD and pneumonia reduce life expectancy for the remaining lifetime and highlights the need to further improve post-fracture management.

Abstract
UNLABELLED Incidence of hip fracture increased in Korean populations over age 50 between 2008 and 2012, and the number of fractures was predicted to increase by 1.4 times by 2025. This is important information for public health planning. INTRODUCTION The purposes of this study were to evaluate the trends in the incidence and mortality of hip fracture between 2008 and 2012 and predict the number of hip fractures in Korea through 2025 using nationwide claims data. METHODS The data managed by the National Health Insurance Service were used to identify the hip fractures in patients aged >50 years between 2008 and 2012. Projections of hip fractures were conducted using the Poisson distribution from 2016 to 2025 in Korea. RESULTS The incidence of hip fractures (per 100,000) increased by 14.1 % over the 5 years of the study, by 15.8 % in women and 10.9 % in men; the older age group showed a steep rise and shift in the incidence from 2008 to 2012. The cumulative mortality rates at 1 year after hip fractures were 17.2 % (3575/20,849) in 2008 and 16.0 % (4547/28,426) in 2012. Overall standardized mortality ratios (SMRs) for hip fracture were higher in men (11.93) than in women (11.22) and were higher than those in the general population in all age groups. In 2016, the total number of hip fractures was estimated to increase an overall of 1.4 times by 2025. CONCLUSIONS The incidence of hip fracture continues to increase, and the related mortality is still high, although it has decreased over time. The socioeconomic burden of hip fracture is expected to increase in Korea along with the increased estimated number of fractures. Nationwide strategies should include attempts to reduce the future socioeconomic burdens of hip fractures.

Abstract
UNLABELLED This study estimated the fracture-related mortality and direct medical costs among postmenopausal women in Taiwan by fracture types and age groups by utilizing a nationwide population-based database. Results demonstrated that hip fractures constituted the most severe and expensive complication of osteoporosis across fracture sites. INTRODUCTION The aims of the study were to evaluate the risk of death and direct medical costs associated with osteoporotic fractures by fracture types and age groups among postmenopausal women in Taiwan. METHODS This nationwide, population-based study was based on data from the National Health Insurance Research Database in Taiwan. Female patients aged 50 years and older in the fracture case cohort were matched in 1:1 ratio with randomly selected subjects in the reference control cohort by age, income-related insurance amount, urbanization level, and the Charlson comorbidity index. There were two main outcome measures of the study: age-differentiated mortality and direct medical costs in the first and subsequent years after osteoporotic fracture events among postmenopausal women. The bootstrap method by resampling with replacement was conducted to generate descriptive statistics of mortality and direct medical costs of the case and control cohorts. Student's t tests were then performed to compare mortality and costs between the two cohorts. RESULTS A total of 155,466 postmenopausal women in the database met the inclusion criteria for the fracture case cohort, including 22,791 hip fractures, 72,292 vertebral fractures, 15,621 upper end humerus (closed) fractures, 36,774 wrist fractures, and 7,988 multiple fractures. Analytical results demonstrated that patients experiencing osteoporotic fractures were at considerable excess risk of death and incurred substantially higher treatment costs, notably for hip fractures. Furthermore, results also revealed that the risk of mortality increased with advancing age across the spectrum of fracture sites. CONCLUSIONS The present study confirmed an excess mortality and higher direct medical costs associated with osteoporotic fractures. Moreover, hip fractures constituted the most severe and expensive complication of osteoporosis among fracture types.

Years of life lost due to lower extremity injury in association with dementia, and care need: a 6-year follow-up population-based study using a multi-state approach among German elderly. BMC Geriatr 2016; 16:9. [PMID: 26758623 PMCID: PMC4710990 DOI: 10.1186/s12877-016-0184-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2015] [Accepted: 01/04/2016] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Dementia and care need are challenging aging populations worldwide. Lower extremity injury (LEI) in the elderly makes matters worse. Using a multi-state approach, we express the effect of LEI on dementia, care need, and mortality in terms of remaining life expectancy at age 75 (rLE) and years of life lost (YLL). METHODS A population-based random sample of beneficiaries aged 75-95 years was drawn from the largest public health insurer in Germany in 2004 and followed until 2010 (N 62,103; Mean Age ± SD 81.5 ± 4.8 years; Female 71.2%). We defined a five-state model (Healthy, Dementia, Care, Dementia & Care, Dead), and calculated transition-specific hazard ratios of LEI using Cox regression. The transition probabilities as well as the YLL due to LEI were estimated. RESULTS LEI significantly increased the risk for each transition, with a maximum risk for the transition from Healthy to Care (HR: 1.70, 95% CI: 1.63-1.77) and a minimum risk for the transition from Care to Dead (HR: 1.16, 95% CI: 1.10-1.22). If the elderly had LEI-history, their age-specific mortality was generally higher and their probabilities of transient states peaked at younger ages. At age 75, initially dementia-free and care-independent elderly experiencing LEI lost about 2 years of life, of which more than 90% were life years free of dementia or care need. Dementia patients lost about one and a half year, more than 60% were free of long-term care need. CONCLUSIONS LEI not only casts a large health burden on care need, but is also associated with cognitive decline and shortened rLE. LEI plus dementia extend the relative life time in need of care, despite generally shortening rLE. Using the composite measure YLL may help to better convey these results to the elderly, families, and health professionals. This may strengthen preventive measures as well as improve timely and rehabilitative treatment of LEI, not only in cognitive and physically intact elderly.

Abstract
SUMMARY The present meta-analysis shows that a nonlinear association between alcohol consumption and the risk of hip fracture was observed. Light alcohol consumption was inversely significantly associated with hip fracture risk, whereas heavy alcohol consumption was associated with an elevated hip fracture risk. INTRODUCTION Previous studies examining the association between alcohol consumption and the risk of hip fracture have reported conflicting findings. Therefore, we conducted a meta-analysis of prospective cohort studies to assess the association between alcohol consumption and the risk of hip fracture. METHODS PubMed and EMBASE were searched for prospective cohort studies on the relationship between alcohol consumption and the risk of hip fractures. Relative risks (RR) with 95% confidence intervals (CI) were derived using random-effects models throughout the whole analysis. RESULTS Eighteen prospective cohort studies were included with 3,730,424 participants and 26,168 hip fracture cases. Compared with non-drinkers, the pooled RR of hip fractures for alcohol consumption was 1.03 (95% CI, 0.91-1.15), with high heterogeneity between studies (P<0.001, I2=72.6%). A nonlinear relationship between alcohol consumption and the risk of hip fracture was identified (P nonlinearity=0.003). Compared with non-drinkers, the pooled RRs of hip fractures were 0.88 (95% CI, 0.83-0.89) for light alcohol consumption (0.01-12.5 g/day), 1.00 (95% CI, 0.85-1.14) for moderate alcohol consumption (12.6-49.9 g/day), and 1.71 (95% CI, 1.41-2.01) for heavy alcohol consumption (≥50 g/day). CONCLUSIONS There was no evidence of publication bias. In conclusion, a nonlinear association between alcohol consumption and the risk of hip fracture was observed in this meta-analysis. Further, light alcohol consumption was inversely significantly associated with hip fracture risk, whereas heavy alcohol consumption was associated with an elevated hip fracture risk.

Abstract
SUMMARY Loop diuretic use has been shown to be associated with an increased fracture risk, but the findings have been inconsistent. The present meta-analysis suggests that loop diuretics show a significant positive association with the overall risk of total fractures and, specifically, hip fractures. INTRODUCTION Despite being widely used, there is limited, prospective randomized trial evidence regarding the skeletal effects of loop diuretics. Previous observational studies have reported conflicting findings regarding the association between loop diuretic use and the risk of fractures. METHODS This meta-analysis of observational studies assessed the association between loop diuretic use and the risk of fractures. The PubMed, EMBASE, and OVID databases were searched for prospective cohort and case-control studies. Relative risks (RR) with 95% confidence intervals (CI) were derived using random-effects models throughout the analysis. RESULTS Thirteen studies (4 cohort studies and 9 case-control studies) were included, involving 842,644 participants and 108,247 fracture cases. Compared with non-users, people who had taken loop diuretics had an approximately 15% higher risk of total fractures (95% CI, 1.04-1.26; p<0.01), with high heterogeneity between studies (I2=80.5%; p<0.01). The RR was 1.14 (95% CI, 1.08-1.19) for hip fractures and 0.99 (95% CI, 0.93-1.05) for lower arm or wrist fractures. The RR was 1.05 (95% CI, 1.00-1.11) in prospective cohort studies and 1.22 (95% CI, 1.00-1.44) in case-control studies. There was no evidence of publication bias. CONCLUSION The results suggest that loop diuretics show a significant positive association with the overall risk of total fractures and hip fractures.

[PMID: 25380128 PMCID: PMC4224412 DOI: 10.1371/journal.pone.0112098] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2014] [Accepted: 10/12/2014] [Indexed: 11/19/2022] Open
Abstract
Increased mortality rates in patients sustaining hip and vertebral fractures are well documented; however in distal radius fracture patients the results are conflicting. The aim of this study was to examine short- and long-term mortality in distal radius fracture patient in comparison with the background population. Patients aged ≥50 years with distal radius fracture living in Southern Norway who suffered a fracture in the two year period 2004 and 2005 were included in the study. The mortality risk of the standard Norwegian population was used to calculate the standardized mortality ratio (SMR). The number of distal radius fractures was 883 (166 men and 717 women). Mean age was 69 years (men 65 years and women 70 years). After one year the overall mortality rate was 3.4% (men 5.4% and women 2.9%) and after five years 4.6% (men 4.0% and women 4.8%). The SMR for men and women compared to the Norwegian population for the first year was 1.6 (95% confidence interval (CI): 0.6, 2.7) and 0.9 (95% CI: 0.4, 1.2), respectively, and after five years 1.7 (95% CI: 0.3, 3.0) and 2.0 (95% CI: 1.2, 2.7). Stratified on age groups (50–70 and >70 years) an increased SMR was only seen in female patients aged >70 years five years after the fracture (SMR: 1.9, 95% CI: 1.1, 2.6). In conclusion, increased SMR was found in female patients aged >70 years five years after the distal radius fracture, but not in men or in women younger than 70 years.

[PMID: 24677169 PMCID: PMC4133107 DOI: 10.1002/jbmr.2193] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2013] [Revised: 01/07/2014] [Accepted: 01/21/2014] [Indexed: 11/12/2022]
Abstract
To determine the extent to which excess mortality after fractures attributable to particular causes at specific skeletal sites can be predicted using data about all medical diagnoses, we conducted a historical cohort study among 1991 Olmsted County, Minnesota, residents aged ≥ 50 years who experienced any fracture in 1989 to 1991 and who were followed passively for up to 22 years for death from any cause. We used a machine learning approach, gradient boosting machine (GBM) modeling, to determine whether the comorbid conditions present at the time of fracture and those that arose subsequently could, in aggregate, identify patients at the greatest increased risk of death. During 21,867 person-years of follow-up, 1245 deaths were observed when 1061 were expected (standardized mortality ratio, 1.2; 95% confidence interval [CI] 1.1-1.2). Patients presented with a median history of 26 comorbid conditions each as assessed by the Clinical Classification Software system and 57 each over the total duration of follow-up. Using all available information, the excess deaths could be predicted with good accuracy (c-index ≥ 0.80) in 89% of the GBM models built for patients with different types of fracture; in one-third of the models, the c-index was ≥ 0.90. The conditions most prominent in the GBM prediction models were also reflected in the specific causes of death that were elevated, suggesting the influence of confounding on the relationship. However, the predominant comorbid conditions were mainly those responsible for mortality in the general population, rather than the specific diseases most closely associated with secondary osteoporosis. To reduce long-term deaths in the fracture population as a whole, a more general approach to the fracture patient is indicated.

Abstract
INTRODUCTION The world's population is ageing and the elderly population itself is growing older. This population shows a high incidence of hip fractures. We performed a retrospective study, reviewing the functional status, postoperative complications and mortality rate of nonagenarians who underwent surgery for hip fracture. METHODS AND SUBJECTS 56 nonagenarian patients underwent hip fracture surgery in our institution between January 2000 and December 2010. Two of these patients had presented with hip fracture on separate occasions, giving a total of 58 hips for analysis. Patients with open fracture, subtrochanteric fracture, polytrauma and pathological fracture were excluded. The case notes, electronic records and X-rays for all those included in the study were reviewed. The main outcome measures were functional status, postoperative complications and mortality rate at 1 year. RESULTS Patients with extracapsular hip fractures were associated with higher risks of postoperative complications (60.7 %; p = 0.037), mortality (25 %; p = 0.003) and more likely to be non-ambulant at 1 year (53.6 vs 16.7 %; p = 0.003). Females were more likely to suffer postoperative complications than males (p = 0.016). 46.6 % of the patients had immediate postoperative complications and most commonly due to urological complications (29.3 %). The 1-year mortality rate was 12.1 %. A notable proportion of patients (65.5 %) remained ambulant 1 year postoperatively, although almost half of the patients (48.3 %) who could ambulate independently pre-injury required a walking aid after hip fracture surgery. CONCLUSION Nonagenarians have good surgical outcomes after hip fracture surgery with low mortality rate. They should be treated similarly as their younger counterparts in terms of decision for surgery. Potential decline in functional status and rehabilitation options should be shared with the patient and family at an early stage.

BMC Musculoskelet Disord 2014; 15:151. [PMID: 24886144 PMCID: PMC4020382 DOI: 10.1186/1471-2474-15-151] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2013] [Accepted: 04/30/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Hip fracture has a high mortality rate, but the actual level of long-term excess mortality and its impact on population-wide mortality remains controversial. The present prospective study investigated short- and long-term excess mortality after hip fractures with adjustment of other risk factors. We calculated the population attributable risk proportion (PARP) to assess the impact of each risk factor on excess mortality. METHODS We recruited 217 elders with hip fractures and 215 age- and sex-matched patients without fractures from the geriatric department of the same hospital. The mean follow-up time was 46.1 months (range: 35 to 57 months). We recorded data on 55 covariates, including baseline details about health, function, and bone mineral density. We used the multivariate Cox proportional hazards model to analyze hazard ratios (HRs) of short-term (<12 months follow-up) and long-term (≧ 2 months follow-up) excess mortality for each covariate and calculated their PARP. RESULTS Patients with hip fractures had a higher short-term mortality than non-fractured patients, and the long-term excess mortality associated with hip fracture remained high. The significant risk factors for short-term mortality were hip fracture, comorbidities, and lower (below cutoff) Mini Mental State Examination score with HRs of 2.4, 2.3, and 2.3, respectively. Their PARPs were 44.7%, 38.1%, and 34.3%, respectively. The significant risk factors for long-term mortality were hip fracture (HR: 2.7; PARP: 48.0%), lower T-score (HR: 3.3; PARP: 36.2%), lower body mass index (HR: 2.5; PARP: 42.8%), comorbidities (HR: 2.1; PARP: 34.8%), difficulty in activities of daily living (HR: 1.9; PARP: 31.8%), and smoking (HR: 2.5; PARP: 19.2%). CONCLUSIONS After comprehensive adjustment, hip fracture was a significant risk factor and contributed the most to long-term as well as short-term excess mortality. Its adequate prevention and treatment should be targeted.

Abstract
UNLABELLED A hip fracture results in a lower quality of life and a cost of £30,000. In this study, one-leg standing time (OLST) had a negative linear relationship to the risk of a hip fracture. OLST could be a useful tool to assess the need for fracture-preventive interventions. INTRODUCTION A hip fracture immobilizes, restricts autonomy, shortens life expectancy, and results in a cost of £30,000 in the UK health care system. However, effective preventive treatments can be offered to high-risk individuals. Impaired postural balance is an important risk factor for hip fractures, and the aim of this study was to evaluate whether OLST can predict hip fractures in elderly women. FRAX is the most established fracture risk assessment tool worldwide and a secondary aim was to relate the predictive ability of OLST to that of FRAX in this population. METHODS Three hundred fifty-one women aged between 69 and 79 years were timed standing on one leg up to 30 s with eyes open and assessed with FRAX. Fracture data was obtained from registers. RESULTS The main outcome, a hip fracture, occurred in 40 of the 351 participants (11.4%). The age-adjusted risk of a hip fracture was 5% lower with 1 s longer OLST (Hazard ratio 0.95, 95% CI 0.927-0.978). The relation between OLST and hip fracture risk was linear. Harrell's c was 0.60 for FRAX and 0.68 for OLST adjusted for age. CONCLUSION With 1 s longer OLST, the risk of a hip fracture decreased significantly by 5%. This risk reduction was not explained by differences in the classic fracture risk factors included in FRAX. OLST had a predictive ability similar to FRAX. OLST is an easily performed balance test which may prove to be valuable in the assessment of hip fracture risk.

Abstract
UNLABELLED Temporal trends in hip fracture incidence have recently been reported in some developed countries. Such data in Spain has previously been incomplete; this study reports the stratified incidence of hip fractures in people over 65 in Spain during the last 14 years. INTRODUCTION The main objective is to establish whether temporal trends in hip fracture incidence in Spain exist. METHODS Ecological study with data from hospital discharges nationwide. The study includes patients aged ≥ 65 years during a 14-year period (1997-2010). The analysis compares two periods of four years: 1997-2000 (P1) and 2007-2010 (P2). RESULTS There were 119,857 fractures in men and 415,421 in women. Comparing periods (P1 vs P2) over 10 years, the crude incidence rate/100,000 inhabitant/year increased an average of 2.3%/year in men and 1.4% in women. After adjustment, the rate increased an average of 0.4%/year in men (p < 0.0001), but decreased 0.2%/year in women (p < 0.0001). In men, younger than 85, the decrease was not significant except in 70-74 years, and from 80 years, the adjusted rate increases significantly (p < 0.0001). In women under 80 years of age, the decrease in adjusted rate was significant; there was no change in 80-84 years, and the adjusted rate increased significantly in individuals 85 years and older (p < 0.0001). Mortality rates declined by 22% in both sexes, and the index of overaging population rises 30.1 % in men and 25.2% in women. CONCLUSIONS This study supports other international studies by showing changes in the incidence of hip fractures after age-population adjustment, which denotes a decrease in the younger age groups and among women and shows an increase in both groups over 85 years. The increase in the crude incidence rate of hip fracture in Spain reflects changes in population structure.

Abstract
The aim of this study was to determine whether home modification was associated with subsequent progression of frailty and mortality in older adults. We conducted a prospective cohort study in 574 adults 65 and older who required a low or moderate level of care. Of these, 34% modified their homes-most frequently a corridor-and the most common type of modification was the installation of handrails. The mortality was significantly lower among older adults with home modifications than in those without home modifications at 2 years (adjusted hazard ratio [HR] = 0.52; 95% confidence interval [CI] [0.32, 0.87]), 3 years (HR = 0.57, 95% CI [0.54, 0.81]), and 4.7 years (HR = 0.65, 95% CI [0.65, 0.91]). These findings suggest that home modification may prevent the progression of frailty (i.e., need for low/moderate level of care increasing to the need for high level of care) in older adults.

Abstract
Mortality after hip fracture is a major problem in the Western world, but its mechanisms remain uncertain. This study assessed the 2-year mortality rate after hip fracture in elderly patients by including hospital factors (eg, intervention type, surgical delay), underlying health conditions, and, for a subset, lifestyle factors (eg, body mass index, smoking, alcohol). A total of 828 patients (183 men) 70 to 99 years old experiencing a hip fracture in 2009 in the province of Varese were included in the study. The risk factors for death were assessed through Kaplan-Meier analysis and Cox proportional hazards analysis. Hip fracture incidence per 1000 persons was higher in women (8.4 vs 3.7 in men) and in elderly patients (12.4 for 85-99 years vs 4.4 for 70-84 years). The mortality rate after 1, 6, 12, and 24 months was 4.7%, 16%, 20.7%, and 30.4%, respectively. For the province of Varese, sex (hazard ratio, 0.39 for women), age group (hazard ratio, 2.2 for 85-99 years), and Charlson Comorbidity Index score (hazard ratio, 2.06 for score greater than 1) were found to be statistically significant. The 2-year mortality rate in hip fractures is associated with sex, age, and comorbidities. Male sex, age older than 85 years, and Charlson Comorbidity Index score greater than 1 are associated with a higher risk. Surgical delay was significant in the Kaplan-Meier survival time analysis but not in the Cox hazard analysis, suggesting that early surgery reduces risk in patients with numerous comorbidities.

Abstract
BACKGROUND Past studies of relationships between alcohol and hip fracture have generally focused on total alcohol consumed and not type of alcohol. Different types of alcohol consist of varying components which may affect risk of hip fracture differentially. This study seeks to examine the relationship between alcohol consumption, with a focus on type of alcohol consumed (e.g. beer, wine, or hard liquor) and hip fracture risk in post-menopausal women. METHODS The longitudinal cohort consisted of U.S. post-menopausal women aged 50-79 years enrolled between 1993-1998 in the Women's Health Initiative Clinical Trials and Observational Study (N=115,655). RESULTS Women were categorized as non-drinkers, past drinkers, infrequent drinkers and drinkers by preference of alcohol type (i.e. those who preferred wine, beer, hard liquor, or who had no strong preference). Mean alcohol consumption among current drinkers was 3.3 servings per week; this was similar among those who preferred wine, beer and liquor. After adjustment for potential confounders, alcohol preference was strongly correlated with hip fracture risk (p = 0.0167); in particular, women who preferred wine were at lower risk than non-drinkers (OR=0.78; 95% CI 0.64-0.95), past drinkers (OR=0.85; 95% CI 0.72-1.00), infrequent drinkers (OR=0.73; 95% CI 0.61-0.88), hard liquor drinkers (OR=0.87; 95% CI 0.71-1.06), beer drinkers (OR=0.72; 95% CI 0.55-0.95) and those with no strong preference (OR=0.89; 95% CI 0.89; 95% CI 0.73-1.10). CONCLUSIONS Preference of alcohol type was associated with hip fracture; women who preferentially consumed wine had a lower risk of hip fracture compared to non-drinkers, past drinkers, and those with other alcohol preferences.

Abstract
BACKGROUND Patients who sustain osteoporotic fractures have excessive mortality compared to age-matched controls, which is most pronounced within the first 6 months postfracture. However, the timing and cause of death in the first 3 months after sustaining a fracture are unclear. QUESTIONS/PURPOSES We therefore evaluated and compared the timing and cause of death in patients who sustained a pelvic, proximal femoral, spinal, or proximal humeral fracture 30 and 90 days after fracture. METHODS From medical records, we recorded age at time of fracture, sex, fracture site, comorbidities, date of death, and cause of death of 1630 patients with 1630 fractures admitted to our department between 2001 and 2007. The median age at the time of fracture was 83 years and 89% of the patients were women. RESULTS Fifty-eight patients died within 30 days after fracture (3.6%), and 122 patients (7.5%) died within 90 days after fracture. Cardiovascular causes of death were most frequent in all fracture groups. Patients who suffered from spinal fractures died earlier within 30 days after fracture than patients who suffered from other types of fractures. CONCLUSIONS This shows the severity and impact of a spinal injury compared to other typical fragility fractures.

Abstract
Osteoporotic hip fractures cause high mortality in the elderly population. However, few population studies reported the long-term mortality of hip fracture among the elderly in Asian population. This study assessed the incidence, excess mortality, and risk factors after osteoporotic hip fractures through inpatients aged 60 years or older. A total of 143,595 patients with hip fracture were selected from Taiwan National Health Insurance database in the years 1999 to 2009 and followed up until the end of 2010. Annual incidence, mortality and SMR, and mortality and SMR at different periods after fracture were measured. From 1999 to 2005, hip fracture incidence gradually increased and then fluctuated after 2006. From 1999 to 2009, the male-to-female ratio of annual incidence increased from 0.60 to 0.66, annual mortality for hip fracture decreased from 18.10% to 13.98%, male-to-female ratio of annual mortality increased from 1.38 to 1.64, and annual SMR decreased from 13.80 to 2.98. Follow-up SMR at one, two, five, and ten years post-fracture was 9.67, 5.28, 3.31, and 2.89, respectively. Females had higher follow-up SMR in the younger age groups (60-69 yr of age) but lower follow-up SMR in the older age groups (over 80 yr of age) compared with males. Among the studied patients, incidence is gradually decreasing along with annual mortality and SMR. Hip fracture affects short-term but not long-term mortality.

Abstract
Background Hip fracture patients have, in several studies, been shown to have excessive mortality. There is, however, a lack of mortality data, in comparison to incidence data, from the last decade in particular. Objective To study short- and long-term mortality in a population-based cohort of hip fracture patients over the last decade and compare it to the background population. Patients and methods Fragility hip fracture patients in the two most southern counties in Norway who experienced fractures in 2004 and 2005 were studied. For each patient, three controls were randomly recruited from the background population matched for age, sex, and residency. Overall, age-, gender-, and group-specific mortality rates were calculated. Results A total of 942 (267 male and 675 female) patients with a fragility hip fracture were identified. In the hip fracture patients, overall mortality rate after 1 year was 21.3% (males 30.7% and females 19.1%, P < 0.005) and, after 5 years, 59.0% (males 70.0% and females 54.6%, P < 0.005). The corresponding figures for matched controls were 5.6% (males 5.9%, females 5.4%, P = 0.6) and 24.9% (males 25.9%, females 24.5%, P = 0.4), respectively. A statistically significant difference was seen in the log-rank statistical analysis between hip fracture patients and controls, both in males (P < 0.0005) and females (P < 0.0005), and for age groups 50–80 years (P < 0.0005) and 80 years and older (P < 0.0005). Conclusion Mortality in males and females with hip fractures is high not only in the first year after fracture, but remains higher than in the background population during 5 years of follow-up. The high mortality in hip fracture patients remains a challenge both in middle-aged and elderly individuals. Optimization of post-fracture treatment and care could reduce mortality of hip fracture in middle-aged and elderly individuals.

Abstract
INTRODUCTION Osteoporosis-related fractures of the proximal femur cause significant morbidity and result in an economic burden on societies. It remains debatable whether diabetic patients with proximal fracture of the femur demonstrate poorer outcomes in terms of hospital stay and mortality compared to non-diabetic controls. METHODS All patients over 65years old admitted to the University Hospital Birmingham during 2007-2010 with a diagnosis of a fracture of the proximal femur (total 1468 including 197 patients with diabetes) were analysed. Eligibility and case definitions were ascertained using electronic records. Multivariate analyses were conducted to control for the confounding effect of covariates, which may be associated with the outcomes of interest on the basis of biological plausibility and known risks. RESULTS In-patient mortality was estimated at 14.2% and 12% for the diabetic and non-diabetic patients respectively. Diabetes was not found to be a significant predictor of in-patient mortality, before and after adjustment for the covariates [Adjusted odds ratio 1.01 (95% CI 0.62-1.65)], in contrast to advancing age, male gender, co-morbidity score, low albumin and high creatinine concentrations. Similarly, median length of stay was greater in the diabetes patients, yet only by a day (20 versus 19 days). This was not statistically significant in either the unadjusted (p=0.17) or in the multivariate analysis (p=0.06). CONCLUSIONS Diabetic patients admitted with fracture of the proximal femur did not demonstrate significantly poorer outcomes in terms of in-patient mortality and length of stay compared to non-diabetic patients.

Hospitalised hip fracture risk with rosiglitazone and pioglitazone use compared with other glucose-lowering drugs. Diabetologia 2012; 55:2929-37. [PMID: 22945303 PMCID: PMC3464390 DOI: 10.1007/s00125-012-2668-0] [Citation(s) in RCA: 106] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2012] [Accepted: 06/25/2012] [Indexed: 01/12/2023]
Abstract
AIMS/HYPOTHESIS Current drug labels for thiazolidinediones (TZDs) warn of increased fractures, predominantly for distal fractures in women. We examined whether exposure to TZDs affects hip fracture in women and men and compared the risk to that found with other drugs used in diabetes. METHODS Using a nationwide database of prescriptions, hospital admissions and deaths in those with type 2 diabetes in Scotland we calculated TZD exposure among 206,672 individuals. Discrete-time failure analysis was used to model the effect of cumulative drug exposure on hip fracture during 1999-2008. RESULTS There were 176 hip fractures among 37,479 exposed individuals. Hip fracture risk increased with cumulative exposure to TZD: OR per year of exposure 1.18 (95% CI 1.09, 1.28; p = 3 × 10(-5)), adjusted for age, sex and calendar month. Hip fracture increased with cumulative exposure in both men (OR 1.20; 95% CI 1.03, 1.41) and women (OR 1.18; 95% CI 1.07, 1.29) and risks were similar for pioglitazone (OR 1.18) and rosiglitazone (OR 1.16). The association was similar when adjusted for exposure to other drugs for diabetes and for other potential confounders. There was no association of hip fracture with cumulative exposure to sulfonylureas, metformin or insulin in this analysis. The 90-day mortality associated with hip fractures was similar in ever-users of TZD (15%) and in never-users (13%). CONCLUSIONS/INTERPRETATION Hip fracture is a severe adverse effect with TZDs, affecting both sexes; labels should be changed to warn of this. The excess mortality is at least as much as expected from the reported association of pioglitazone with bladder cancer.
