Summary
A large international meta-analysis using primary data from 64 cohorts has quantified the increased risk of fracture associated with a previous history of fracture for future use in FRAX.
Introduction
The aim of this study was to quantify the fracture risk associated with a prior fracture on an international basis and to explore the relationship of this risk with age, sex, time since baseline and bone mineral density (BMD).
Methods
We studied 665,971 men and 1,438,535 women from 64 cohorts in 32 countries followed for a total of 19.5 million person-years. The effect of a prior history of fracture on the risk of any clinical fracture, any osteoporotic fracture, major osteoporotic fracture, and hip fracture alone was examined using an extended Poisson model in each cohort. Covariates examined were age, sex, BMD, and duration of follow-up. The results of the different studies were merged by using the weighted
β
-coefficients.
Results
A previous fracture history, compared with individuals without a prior fracture, was associated with a significantly increased risk of any clinical fracture (hazard ratio, HR = 1.88; 95% CI = 1.72–2.07). The risk ratio was similar for the outcome of osteoporotic fracture (HR = 1.87; 95% CI = 1.69–2.07), major osteoporotic fracture (HR = 1.83; 95% CI = 1.63–2.06), or for hip fracture (HR = 1.82; 95% CI = 1.62–2.06). There was no significant difference in risk ratio between men and women. Subsequent fracture risk was marginally downward adjusted when account was taken of BMD. Low BMD explained a minority of the risk for any clinical fracture (14%), osteoporotic fracture (17%), and for hip fracture (33%). The risk ratio for all fracture outcomes related to prior fracture decreased significantly with adjustment for age and time since baseline examination.
Conclusion
A previous history of fracture confers an increased risk of fracture of substantial importance beyond that explained by BMD. The effect is similar in men and women. Its quantitation on an international basis permits the more accurate use of this risk factor in case finding strategies.

Nutritional status as independent prognostic factor of outcome and mortality until five years after hip fracture: a comprehensive prospective study
2024
Summary
We determined the prognostic value of nutritional status for outcome after hip fracture. Nutritional status was a strong independent prognostic factor for clinical outcome and 5-year mortality. Physical function showed incomplete recovery. Elderly care should focus on prevention already before hip fracture.
Purpose
To determine the prognostic value of nutritional status in hip fracture patients for multiple clinical and functional outcomes over 6 months, and for new fractures and survival over 5 years post-fracture.
Methods
We included 152 well-characterized subjects (age 55+ years) with a hip fracture from a previously published randomized controlled trial. Nutritional status was appraised using the Mini Nutritional Assessment (MNA). Multivariable linear, logistic and Cox regression models were fitted, adjusted for age, sex, ASA score, group and additional prognostic covariates identified in backward regression models.
Results
At baseline, impaired nutritional status was significantly associated with physical disability, depression, impaired cognition and lower quality of life. Prospective analyses showed that impaired baseline nutritional status was an independent prognostic factor for postoperative complications (OR 2.00, 95%CI 1.01–3.98,
p
= 0.047), discharge location from hospital (home vs. rehabilitation clinic, OR 0.41, 95%CI 0.18–0.98,
p
= 0.044), hospital readmission (OR 4.59, 95%CI 1.70–12.4,
p
= 0.003) and total length of hospital stay (HR of being discharged: 0.63, 96%CI 0.44–0.89,
p
= 0.008), as well as for 5-year mortality (HR 3.94, 95%CI 1.53–10.2,
p
= 0.005), but not for risk of new fractures (5y-HR 0.87, 95%CI 0.34–2.24,
p
= 0.769). Curves of physical disability over time showed that the three nutritional status categories followed almost parallel trajectories from baseline until 6 months after hip fracture, without complete recovery and even with further deterioration in malnourished subjects from 3 to 6 months post-fracture.
Conclusion
As baselline nutritional status is a strong independent prognostic factor for clinical outcome after hip fracture, affecting even five-year survival, elderly health care should focus on prevention and identification of at-risk individuals already before hip fracture.

Spinal Anesthesia or General Anesthesia for Hip Surgery in Older Adults
2021
A randomized trial evaluating spinal as compared with general anesthesia for hip-fracture surgery in adults 50 years of age or older did not show superiority of spinal anesthesia with respect to a composite of death or an inability to walk unassisted at 60 days. Postoperative delirium occurred in similar percentages of patients in the two groups.

Screening in the community to reduce fractures in older women (SCOOP): a randomised controlled trial
2018
Despite effective assessment methods and medications targeting osteoporosis and related fractures, screening for fracture risk is not currently advocated in the UK. We tested whether a community-based screening intervention could reduce fractures in older women.
We did a two-arm randomised controlled trial in women aged 70–85 years to compare a screening programme using the Fracture Risk Assessment Tool (FRAX) with usual management. Women were recruited from 100 general practitioner (GP) practices in seven regions of the UK: Birmingham, Bristol, Manchester, Norwich, Sheffield, Southampton, and York. We excluded women who were currently on prescription anti-osteoporotic drugs and any individuals deemed to be unsuitable to enter a research study (eg, known dementia, terminally ill, or recently bereaved). The primary outcome was the proportion of individuals who had one or more osteoporosis-related fractures over a 5-year period. In the screening group, treatment was recommended in women identified to be at high risk of hip fracture, according to the FRAX 10-year hip fracture probability. Prespecified secondary outcomes were the proportions of participants who had at least one hip fracture, any clinical fracture, or mortality; and the effect of screening on anxiety and health-related quality of life. This trial is registered with the International Standard Randomised Controlled Trial registry, number ISRCTN 55814835.
12 483 eligible women were identified and participated in the trial, and 6233 women randomly assigned to the screening group between April 15, 2008, and July 2, 2009. Treatment was recommended in 898 (14%) of 6233 women. Use of osteoporosis medication was higher at the end of year 1 in the screening group compared with controls (15% vs 4%), with uptake particularly high (78% at 6 months) in the screening high-risk subgroup. Screening did not reduce the primary outcome of incidence of all osteoporosis-related fractures (hazard ratio [HR] 0·94, 95% CI 0·85–1·03, p=0·178), nor the overall incidence of all clinical fractures (0·94, 0·86–1·03, p=0·183), but screening reduced the incidence of hip fractures (0·72, 0·59–0·89, p=0·002). There was no evidence of differences in mortality, anxiety levels, or quality of life.
Systematic, community-based screening programme of fracture risk in older women in the UK is feasible, and could be effective in reducing hip fractures.

Summary
The Women's Health Initiative (WHI) double-blind, placebo-controlled clinical trial randomly assigned 36,282 postmenopausal women in the U.S. to 1,000 mg elemental calcium carbonate plus 400 IU of vitamin D
3
daily or placebo, with average intervention period of 7.0 years. The trial was designed to test whether calcium plus vitamin D supplementation in a population in which the use of these supplements was widespread would reduce hip fracture, and secondarily, total fracture and colorectal cancer.
Introduction
This study further examines the health benefits and risks of calcium and vitamin D supplementation using WHI data, with emphasis on fractures, cardiovascular disease, cancer, and total mortality.
Methods
WHI calcium and vitamin D randomized clinical trial (CT) data through the end of the intervention period were further analyzed with emphasis on treatment effects in relation to duration of supplementation, and these data were contrasted and combined with corresponding data from the WHI prospective observational study (OS).
Results
Among women not taking personal calcium or vitamin D supplements at baseline, the hazard ratio [HR] for hip fracture occurrence in the CT following 5 or more years of calcium and vitamin D supplementation versus placebo was 0.62 (95 % confidence interval (CI), 0.38–1.00). In combined analyses of CT and OS data, the corresponding HR was 0.65 (95 % CI, 0.44–0.98). Supplementation effects were not apparent on the risks of myocardial infarction, coronary heart disease, total heart disease, stroke, overall cardiovascular disease, colorectal cancer, or total mortality, while evidence for a reduction in breast cancer risk and total invasive cancer risk among calcium plus vitamin D users was only suggestive.
Conclusion
Though based primarily on a subset analysis, long-term use of calcium and vitamin D appears to confer a reduction that may be substantial in the risk of hip fracture among postmenopausal women. Other health benefits and risks of supplementation at doses considered, including an elevation in urinary tract stone formation, appear to be modest and approximately balanced.

Observational studies have suggested that accelerated surgery is associated with improved outcomes in patients with a hip fracture. The HIP ATTACK trial assessed whether accelerated surgery could reduce mortality and major complications.
HIP ATTACK was an international, randomised, controlled trial done at 69 hospitals in 17 countries. Patients with a hip fracture that required surgery and were aged 45 years or older were eligible. Research personnel randomly assigned patients (1:1) through a central computerised randomisation system using randomly varying block sizes to either accelerated surgery (goal of surgery within 6 h of diagnosis) or standard care. The coprimary outcomes were mortality and a composite of major complications (ie, mortality and non-fatal myocardial infarction, stroke, venous thromboembolism, sepsis, pneumonia, life-threatening bleeding, and major bleeding) at 90 days after randomisation. Patients, health-care providers, and study staff were aware of treatment assignment, but outcome adjudicators were masked to treatment allocation. Patients were analysed according to the intention-to-treat principle. This study is registered at ClinicalTrials.gov (NCT02027896).
Between March 14, 2014, and May 24, 2019, 27 701 patients were screened, of whom 7780 were eligible. 2970 of these were enrolled and randomly assigned to receive accelerated surgery (n=1487) or standard care (n=1483). The median time from hip fracture diagnosis to surgery was 6 h (IQR 4–9) in the accelerated-surgery group and 24 h (10–42) in the standard-care group (p<0·0001). 140 (9%) patients assigned to accelerated surgery and 154 (10%) assigned to standard care died, with a hazard ratio (HR) of 0·91 (95% CI 0·72 to 1·14) and absolute risk reduction (ARR) of 1% (−1 to 3; p=0·40). Major complications occurred in 321 (22%) patients assigned to accelerated surgery and 331 (22%) assigned to standard care, with an HR of 0·97 (0·83 to 1·13) and an ARR of 1% (−2 to 4; p=0·71).
Among patients with a hip fracture, accelerated surgery did not significantly lower the risk of mortality or a composite of major complications compared with standard care.

AbstractObjectiveTo assess the antifracture efficacy and safety of a nutritional intervention in institutionalised older adults replete in vitamin D but with mean intakes of 600 mg/day calcium and <1 g/kg body weight protein/day.DesignTwo year cluster randomised controlled trial.Setting60 accredited residential aged care facilities in Australia housing predominantly ambulant residents.Participants7195 permanent residents (4920 (68%) female; mean age 86.0 (SD 8.2) years).InterventionFacilities were stratified by location and organisation, with 30 facilities randomised to provide residents with additional milk, yoghurt, and cheese that contained 562 (166) mg/day calcium and 12 (6) g/day protein achieving a total intake of 1142 (353) mg calcium/day and 69 (15) g/day protein (1.1 g/kg body weight). The 30 control facilities maintained their usual menus, with residents consuming 700 (247) mg/day calcium and 58 (14) g/day protein (0.9 g/kg body weight).Main outcome measuresGroup differences in incidence of fractures, falls, and all cause mortality.ResultsData from 27 intervention facilities and 29 control facilities were analysed. A total of 324 fractures (135 hip fractures), 4302 falls, and 1974 deaths were observed. The intervention was associated with risk reductions of 33% for all fractures (121 v 203; hazard ratio 0.67, 95% confidence interval 0.48 to 0.93; P=0.02), 46% for hip fractures (42 v 93; 0.54, 0.35 to 0.83; P=0.005), and 11% for falls (1879 v 2423; 0.89, 0.78 to 0.98; P=0.04). The risk reduction for hip fractures and falls achieved significance at five months (P=0.02) and three months (P=0.004), respectively. Mortality was unchanged (900 v 1074; hazard ratio 1.01, 0.43 to 3.08).ConclusionsImproving calcium and protein intakes by using dairy foods is a readily accessible intervention that reduces the risk of falls and fractures commonly occurring in aged care residents.Trial registrationAustralian New Zealand Clinical Trials Registry ACTRN12613000228785.

The orthogeriatric comanagement improves clinical outcomes of hip fracture in older adults
2019
SummaryTreatment of older adults with hip fracture is a healthcare challenge. Orthogeriatric comanagement that is an integrated model of care with shared responsibility improves time to surgery and reduces the length of hospital stay and mortality compared with orthopedic care with geriatric consultation service and usual orthopedic care, respectively.IntroductionTreatment of fractures in older adults is a clinical challenge due partly to the presence of comorbidity and polypharmacy. The goal of orthogeriatric models of care is to improve clinical outcomes among older people with hip fractures. We compare clinical outcomes of persons with hip fracture cared according to orthogeriatric comanagement (OGC), orthopedic team with the support of a geriatric consultant service (GCS), and usual orthopedic care (UOC).MethodsThis is a single-center, pre-post intervention observational study with two parallel arms, OGC and GCS, and a retrospective control arm. Hip fracture patients admitted to the trauma ward were assigned by the orthopedic surgeon to the OGC (n = 112) or GCS (n = 108) group. The intervention groups were compared each with others and both with the retrospective control group (n = 210) of older adults with hip fracture. Several clinical indicators are considered, including time to surgery, length of stay, in-hospital, and 1-year mortality.ResultsPatients in the OGC (OR 2.62; CI 95% 1.40–4.91) but not those in the GCS (OR 0.74; CI 95% 0.38–1.47) showed a higher probability of undergoing surgery within 48 h compared with those in the UOC. Moreover, the OGC (β, − 1.08; SE, 0.54, p = 0.045) but not the GCS (β, − 0.79; SE, 0.53, p = 0.148) was inversely associated with LOS. Ultimately, patients in the OGC (OR 0.31; CI 95 % 0.10–0.96) but not those in the GCS (OR 0.37; CI 95% 0.10–1.38) experienced a significantly lower 1-year mortality rate compared with those in the UOC. All analyses were independent of several confounders.ConclusionsOlder adults with hip fracture taken in care by the OGC showed better clinical indicators, including time to surgery, length of stay and mortality, than those managed by geriatric consultant service or usual orthopedic care.

Summary
The relationship between self-reported falls and fracture risk was estimated in an international meta-analysis of individual-level data from 46 prospective cohorts. Previous falls were associated with an increased fracture risk in women and men and should be considered as an additional risk factor in the FRAX® algorithm.
Introduction
Previous falls are a well-documented risk factor for subsequent fracture but have not yet been incorporated into the FRAX algorithm. The aim of this study was to evaluate, in an international meta-analysis, the association between previous falls and subsequent fracture risk and its relation to sex, age, duration of follow-up, and bone mineral density (BMD).
Methods
The resource comprised 906,359 women and men (66.9% female) from 46 prospective cohorts. Previous falls were uniformly defined as any fall occurring during the previous year in 43 cohorts; the remaining three cohorts had a different question construct. The association between previous falls and fracture risk (any clinical fracture, osteoporotic fracture, major osteoporotic fracture, and hip fracture) was examined using an extension of the Poisson regression model in each cohort and each sex, followed by random-effects meta-analyses of the weighted beta coefficients.
Results
Falls in the past year were reported in 21.4% of individuals. During a follow-up of 9,102,207 person-years, 87,352 fractures occurred of which 19,509 were hip fractures. A previous fall was associated with a significantly increased risk of any clinical fracture both in women (hazard ratio (HR) 1.42, 95% confidence interval (CI) 1.33–1.51) and men (HR 1.53, 95% CI 1.41–1.67). The HRs were of similar magnitude for osteoporotic, major osteoporotic fracture, and hip fracture. Sex significantly modified the association between previous fall and fracture risk, with predictive values being higher in men than in women (e.g., for major osteoporotic fracture, HR 1.53 (95% CI 1.27–1.84) in men vs. HR 1.32 (95% CI 1.20–1.45) in women,
P
for interaction = 0.013). The HRs associated with previous falls decreased with age in women and with duration of follow-up in men and women for most fracture outcomes. There was no evidence of an interaction between falls and BMD for fracture risk. Subsequent risk for a major osteoporotic fracture increased with each additional previous fall in women and men.
Conclusions
A previous self-reported fall confers an increased risk of fracture that is largely independent of BMD. Previous falls should be considered as an additional risk factor in future iterations of FRAX to improve fracture risk prediction.
