Costs of incident non-hip osteoporosis-related fractures in postmenopausal women from a payer perspective.

Osteoporosis-related fractures lead to high morbidity, mortality, and healthcare costs among post-menopausal women. This study showed that incident non-hip osteoporosis-related fractures are frequent among women aged 50 + in Portugal, leading to excessive healthcare costs of €74 million per year, in a conservative scenario. PURPOSE: This study aimed to estimate the costs of incident non-hip osteoporosis-related fractures among postmenopausal women living in Portugal from a payer perspective. METHODS: The study includes women ≥ 50 years old who participated in the baseline assessment (2011-2013) and the first follow-up wave (2013-2015) of the Epidemiology of Chronic Diseases cohort, a Portuguese community-based longitudinal prospective study (n = 2,762). Incident non-hip osteoporosis-related fractures were defined as any self-reported low impact non-hip fractures since baseline. Healthcare resource utilization during the year following fracture was obtained from an informal panel of experts. The amounts of resources used were multiplied by the national tariffs practiced in the National Health Service (NHS) to obtain the cost per patient in the year following a wrist, vertebral, or other site fracture, which was subsequently multiplied by the estimated annual number of incident fractures to obtain the total annual cost of incident non-hip osteoporosis-related fractures among postmenopausal women. RESULTS: Each year approximately 5,000 wrist, 3,500 vertebral, and 39,000 other-site osteoporosis-related fractures occur in women aged 50 + in Portugal. Healthcare costs per patient in the year following fracture vary from €2,709.52 for vertebral fractures to €3,096.35 for other fractures. Non-hip incident osteoporosis-related fractures among 50 + women cost approximately €74 million per year. Among all healthcare services, physiotherapy represents the bulk of costs. CONCLUSIONS: This study pinpoints the relevance of preventing non-hip osteoporosis-related fractures, as these cost about €74 million per year in direct healthcare costs, a substantial impact on the budget of the Portuguese NHS.

Impact of non-hip fractures in elderly women: a narrative review.

The association of hip fractures with adverse outcomes is well established, but for non-hip fractures this association still needs to be further investigated. The objective of this narrative review is to describe the state of the art with regards to the health impact of clinically relevant non-hip fracture locations in postmenopausal women. PubMed and Scopus databases were searched from January 2010 until December 2020. Studies were included when the crude rates and/or relative risk of 1-year subsequent fractures and/or mortality were reported as well as the precise fracture site. Twenty-three studies met the inclusion criteria. Regarding mortality rates, there was a high variability between studies, with higher rates for vertebral, proximal humerus and pelvic fractures. There was a small or no impact of wrist, ankle or tibia fractures. The mortality rate increased with age after vertebral, proximal humerus and wrist fractures. Moreover, proximal humerus and vertebral fractures were associated with a higher mortality risk. This narrative review indicates that, besides fractures of the hip, fractures of the vertebrae, proximal humerus or pelvis deserve more attention when trying to prevent adverse outcomes of osteoporosis. More studies on the topic of non-hip fractures are urgently needed.

Impact of osteoporotic fracture type and subsequent fracture on mortality: the Tromsø Study.

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.

Fracture Burden: What Two and a Half Decades of Dubbo Osteoporosis Epidemiology Study Data Reveal About Clinical Outcomes of Osteoporosis.

PURPOSE OF THE REVIEW: This review aims to highlight important clinical findings from the over 25 year-long Dubbo Osteoporosis Epidemiology Study particularly focusing on outcomes post fracture. RECENT FINDINGS: Every low trauma fracture in the elderly is associated with an increased risk of a subsequent fracture, with a higher risk in men than women. All major or proximal fractures and even minor fractures in the very elderly or minor fractures that are then followed by re-fracture are associated with premature mortality, greatest in the first 5 years post fracture. Having a subsequent fracture further increases this high mortality risk, but if an individual survives the high risk period, their risk returns to that of the background population. Non-hip non-vertebral fractures account for a significant proportion of the premature mortality. Despite an improvement in overall health and population mortality over the years, excess mortality post fracture has not changed in the last 2 decades. All low trauma, fractures in the elderly herald a high risk of poor outcomes, particularly in the first few years post fracture. Early intervention should be initiated.

Non-hip and non-vertebral fractures: the neglected fracture sites.

SUMMARY: Non-hip, non-vertebral fractures (NHNVF) were compared with hip, vertebral and controls. NHNVF were younger and heavier than controls and hip/vertebral fractures in both men and women, respectively. Falls and prior fractures were less common in NHNVF than hip fractures. Glucocorticoid use was lower in NHNVF compared to vertebral fracture (VF) in men. INTRODUCTION: Although hip fracture (HF) and vertebral fractures (VF) receive the most attention in the literature and are the targeted sites for fracture prevention, non-hip, non-vertebral fracture (NHNVF) sites account for a greater proportion of fractures than the hip or vertebrae. This study aimed to assess risk factors for NHNVF and compare them with those for HF, VF and controls. METHODS: Incident fractures during 2005-2007 for men and 1994-1996 for women were identified using computerised keyword searches of radiological reports, and controls were selected at random from electoral rolls for participation in the Geelong Osteoporosis Study. Participants aged 60+ years were included in this study. RESULTS: Compared to controls, men and women with NHNVF were younger (ORs, 0.90, 95% CI 0.86-0.94; and 0.96, 0.93-0.98, respectively) and had a lower femoral neck bone mineral density (BMD) T-score (age-adjusted; difference [men] 0.383, P = 0.002; [women] 0.287, P = 0.001). Compared to HF, men and women with NHNVF were heavier (difference [men] 9.0 kg, P = 0.01; [women] 7.6 kg, P < 0.001). Heavier weight was also a risk factor for women with NHNVF compared to VF (1.03, 1.01-1.06). In men with NHNVF, falls (0.37, 0.14-0.97) and prior fractures (0.38, 0.15-0.98) were less common compared to HF; and glucocorticoid use was less common for NHNVF (0.30, 0.11-0.85) compared to VF. CONCLUSIONS: Given the high numbers of NHNVF sustained by men and women in this study, fracture prevention strategies should focus on individuals with high risk of sustaining these types of fractures, as well as on individuals who are more likely to sustain a HF or VF.

Survival analysis in nonagenarian patients with non-hip lower limb fractures.

BACKGROUND: The United Kingdom has an aging population with nearly 1 in 5 being over the age of 65, and over 0.5 million over the age of 90. The treatment of acute fractures of the lower limb in the nonagenarian cohort of patients poses a technical challenge to orthopaedic surgeons. AIM: To report the fracture incidence, survival outcomes of treating acute non-hip lower limb fractures in nonagenarians in Major Trauma Centre. METHODS: Thirty Lower limb long bone fractures in patients of age from 90 to 99 years were identified during 12-mo at a Level 1 trauma centre from a computerized database. A retrospective evaluation performed for fracture incidence, treatment, length of hospital duration and mortality at 30-d, 1-year and 2-year. RESULTS: Thirty fractures (28 patients) were identified, twenty-four fractures were treated with surgery (mean age 93 years SD ± 2.59) and 6 managed conservatively (mean age 94 years SD ± 2.07). The mean length of the hospital stay was 18.2 d for both groups. The 30-d, 1-year and 2-year mortality risks were 1/23, 6/23 and 9/23 (4%, 26% and 39%) in the surgery group and 0/5, 1/5 and 2/5 (0%, 20% and 40%) in the conservative group, with no evidence for a difference between the two groups at any time point. CONCLUSION: Nonagenarians in the surgical group had similar length of hospital stay and mortality risks as those treated conservatively. Patients with fewer comorbidities and admitted from their own home were offered surgery.

Global biomarkers of oxidative stress and fractures: a matched case-control study.

Background: Evidence for a relationship between oxidative stress and osteoporotic fractures in humans is limited. Fluorescent oxidation products (FlOPs, excitation/emission wavelengths 320/420nm denoted FlOP_320; 360/420nm [FlOP_360]; and 400/475nm [FlOP_400]) are global biomarkers of oxidative stress, and reflect oxidative damage to proteins, phospholipids, and nucleic acids. We investigated the association between FlOPs and a recent osteoporotic fracture. Methods: We conducted a case-control study in a Chinese population aged 50 years or older. A recent osteoporotic fracture in the cases was confirmed by x-ray. Cases were matched with community-based non-fracture controls (1:2 ratio) for age (± 4 years) and sex. In addition, we conducted a sensitivity unmatched case-control study which included all fracture cases and all eligible non-fracture controls prior to matching. Plasma FlOPs were measured with a fluorescent microplate reader. We used unconditional logistic regression to analyze the association between FlOPs (per 1-SD increase in logarithmic scale) and fracture; odds ratios (OR) and 95% confidence intervals (95% CI) were reported. Results: Forty-four cases and 88 matched controls (mean age: 68.2 years) were included. After covariate adjustment (i.e., body mass index, physical activity, and smoking), higher FlOP_360 (OR = 1.85; 95% CI = 1.03 - 3.34) and FlOP_400 (OR = 13.29; 95% CI = 3.48 - 50.69) levels, but not FlOP_320 (OR = 0.56; 95% CI = 0.27 - 1.15), were associated with increased fracture risk. Subgroup analyses by fracture site and unmatched case-control study found comparable associations of FlOP_360 and FlOP_400 with hip and non-hip fractures. Conclusions: Higher FlOP_360 and FlOP_400 levels were associated with increased risk of fracture, and this association was comparable for hip and non-hip fractures. Prospective studies are warranted to confirm this finding.
