Trends in the Diagnosis of Osteoporosis in Patients with Distal Radius Fractures Based on a National Claims Database

Impact of an Outpatient Fracture Liaison Service on Osteoporosis Evaluation Among Patients With Upper Extremity Fragility Fracture

BACKGROUND

The purpose of this study was to assess the impact of implementation of an outpatient fracture liaison service (FLS) on completion rates of dual-energy x-ray absorptiometry (DXA) and screening labs including 25-OH vitamin D and parathyroid hormone (PTH) in patients with upper extremity (UE) fragility fractures.

METHODS

At our institution, 367 patients were treated in 2014-2015 for UE fragility fractures of the distal radius and proximal humerus before implementation of our outpatient FLS and 395 patients in 2017-2018 after implementation. Retrospective chart review was conducted to identify completed DXA scans within 2 years of fracture treatment and completed 25-OH vitamin D and PTH labs within 1 year of fracture treatment.

RESULTS

There were no statistical differences in the demographics of patients treated for distal radial and proximal humeral fragility fractures during the 2014-2015 and 2017-2018 time periods. Implementation of the FLS resulted in a 9.9% increase (P value = .021) in completed DXA scans within 2 years of fracture treatment. Completed 25-OH vitamin D and PTH labs saw a significant increase of 17.1% and 23.8%, respectively (P values < .001).

CONCLUSIONS

Implementation of an outpatient FLS can help to improve osteoporosis evaluation with completed DXA scans and 25-OH vitamin D and PTH labs.

Future Fracture Risk in Upper Extremity Fracture and Non-Fracture Patients

BACKGROUND

Upper extremity (UE) fragility fractures are common and strong predictors of subsequent fractures. To investigate the relative importance of an UE fragility fracture in determining future fracture risk, we conducted a cross-sectional study to compare future fracture risk between patients presenting for osteoporosis evaluation after an UE fragility fracture and a similarly aged cohort of patients without an UE fracture.

METHODS

In all, 129 UE fracture patients seen in our bone health clinic (BHC) and 114 non-fracture UE fracture patients seen in an UE clinic completed clinic intake surveys assessing for fracture risk factors. Prefracture fracture risk (PFFR) and fracture risk assessment tool (FRAX) scores estimated the future fracture risks at the timepoint before and after the UE fragility fracture event, respectively. The primary study outcome was the 10-year risk of future fracture.

RESULTS

The 10-year probability of major osteoporotic and hip fractures were significantly higher among the BHC group when estimated with FRAX. When estimated with PFFR score, there was no difference in the 10-year probability of hip fracture between the groups. Prevalence of secondary osteoporosis and glucocorticoid use was higher in the BHC group, and prevalence of rheumatoid arthritis was higher in the UE clinic group.

CONCLUSIONS

This study underscores the importance of an UE fragility fracture in determining the risk of future fracture. A fragility fracture of the UE should be considered a sentinel event and physicians who evaluate these patients should recognize them as a high-risk group for future hip fracture.

Osteoporosis management and secondary fragility fracture rates in patients with multiple sclerosis: a matched cohort study

This study highlights the persistent osteoporosis treatment gap following fragility fractures. Patients with multiple sclerosis sustained more primary hip fractures than controls and exhibited significantly higher rates of falls within three years post-fracture. However, multiple sclerosis (MS) patients were significantly more likely to be diagnosed with osteoporosis and treated with medications.

INTRODUCTION

The purpose of this study was to compare rates of osteoporosis management, falls, and secondary fractures following primary fragility fractures among patients with MS versus matched controls.

MATERIALS AND METHODS

A retrospective matched cohort study was conducted using the PearlDiver database. Patients aged ≥ 50 years with primary fragility fractures were identified (n = 120,368). Within this population, patients with MS were matched 1:10 with controls across age, sex, and US region. Rates of osteoporosis diagnoses and pharmacologic treatment, low-energy falls, and secondary fragility fractures were compared at three years post-fracture via logistic regression.

RESULTS

A total of 1,232 patients with MS (mean age, 65.7 years) with primary fragility fractures were matched with 12,320 controls (mean age, 65.8 years). Primary hip fractures were significantly more common in the MS cohort (47.4% vs. 34.2%, p < 0.001). After the initial fracture, patients with MS were significantly more likely to receive a formal osteoporosis diagnosis (12.9% vs. 9.7%; OR 1.35; 95% CI, 1.13-1.61) and osteoporosis pharmacotherapy (14.4% vs. 11.9%; OR 1.24; 95% CI, 1.04-1.46). The MS cohort also exhibited significantly higher rates of falls (27.8% vs 22.7%; OR 1.15; 95% CI, 1.01-1.32). Rates of secondary fractures were comparable (6.3% vs. 5.0%; OR 1.10; 95% CI, 0.85-1.40).

CONCLUSION

Primary hip fragility fractures were significantly more common in patients with MS compared to matched controls. Following an initial fracture, patients with MS exhibited a significantly higher rate of falls but were more likely to be diagnosed with osteoporosis and treated with medications.

The global burden of fragility fractures - what are the differences, and where are the gaps

The current burden of fragility fractures is enormous, and it is set to increase rapidly in the coming decades as humankind enters a new demographic era. The purpose of this review is to consider, in different settings: • The human and economic toll of fragility fractures. • Risk factors for fragility fractures. • Current acute management of fragility fractures. • Current care gaps in both secondary and primary fracture prevention. A summary of global, regional, and national initiatives to improve the quality of care is provided, in addition to proposals for the research agenda. Systematic approaches to improve the acute care, rehabilitation and prevention of fragility fractures need to be developed and implemented rapidly and at scale in high-, middle- and low-income countries throughout the world. This must be an essential component of our response to the ageing of the global population during the remainder of the current United Nations - World Health Organization "Decade of Healthy Ageing".

Quality improvement initiatives in the care and prevention of fragility fractures in the Asia Pacific region

This narrative review summarises ongoing challenges and progress in the care and prevention of fragility fractures across the Asia Pacific region since mid-2019. The approaches taken could inform development of national bone health improvement Road Maps to be implemented at scale during the United Nations 'Decade of Healthy Ageing'.

PURPOSE

This narrative review summarises recent studies that characterise the burden of fragility fractures, current care gaps and quality improvement initiatives intended to improve the care and prevention of fragility fractures across the Asia Pacific region.

METHODS

The review focuses on published studies, reports and quality improvement initiatives undertaken during the period July 2019 to May 2022.

RESULTS

Epidemiological studies conducted in countries and regions throughout Asia Pacific highlight the current and projected increasing burden of fragility fractures. Recent studies and reports document a persistent and pervasive post-fracture care gap among people who have sustained fragility fractures. Global initiatives developed by the Fragility Fracture Network and International Osteoporosis Foundation have gained significant momentum in the Asia Pacific region, despite the disruption caused by the COVID-pandemic. The Asia Pacific Fragility Fracture Alliance has developed educational resources including a Hip Fracture Registry Toolbox and a Primary Care Physician Education Toolkit. The Asia Pacific Osteoporosis and Fragility Fractures Society-a new section of the Asia Pacific Orthopaedic Association-is working to engage orthopaedic surgeons across the region in the care and prevention of fragility fractures. The Asia Pacific Consortium on Osteoporosis developed a framework to support national clinical guidelines development groups. Considerable activity at the national level is evident in many countries across the region.

CONCLUSION

Development and implementation of national Road Maps informed by the findings of this review are urgently required to respond to the epidemiological emergency posed by fragility fractures during the United Nations 'Decade of Healthy Ageing'.

Population-based Analysis for Risk of Suicide Death in Elderly Patients after Osteoporotic Fracture: a Nested Case-Control Study

BACKGROUND

The purpose of study was to investigate the incidence rate of suicide in elderly patients with osteoporotic fractures in a nested case-control model and to analyze the change in the risk of suicide death over time after each osteoporotic fracture.

METHODS

We used the National Health Insurance Service-Senior cohort of South Korea. Suicide cases and controls were matched based on sex and age at the index date. Controls were randomly selected at a 1:5 ratio from the set of individuals who were at risk of becoming a case at the time when suicide cases were selected. Conditional logistic regression analysis was performed to evaluate the association between each type of osteoporotic fracture and the risk of suicide death.

RESULTS

Three thousand seventy suicide cases and 15,350 controls were identified. Patients with hip fracture showed an increased risk of suicide death within 1 year of fracture (adjusted odds ratio [aOR] = 2.64; 95% confidence interval [CI], 1.57-4.46; P < 0.001) compared to controls. However, the increased risk of suicide death in patients with hip fracture lasted up to 2 years (aOR = 1.59; 95% CI, 1.04-2.41; P = 0.031). Spine fracture increased the risk of suicide deaths for all observation periods. There was no evidence that humerus fracture increased the risk of suicide death during the observational period. Radius fracture increased only the risk of suicide death within 2 years of fracture (aOR = 1.43; 95% CI, 0.74-2.77; P = 0.282).

CONCLUSION

There were noticeable differences in both degree and duration of increased suicide risks depending on the type of osteoporotic fracture. Mental stress and suicide risk in elderly patients after osteoporotic fracture should be assessed differently depending on the types of fracture.

Fracture Risk Assessment: An Update

➤

Our ability to accurately identify high fracture risk in individuals has improved as the volume of clinical data has expanded and fracture risk assessment tools have been developed.

➤

Given its accessibility, affordability, and low radiation exposure, dual x-ray absorptiometry (DXA) remains the standard for osteoporosis screening and monitoring response to treatment.

➤

The trabecular bone score (TBS) is a DXA software add-on that uses lumbar spine DXA imaging to produce an output that correlates with bone microarchitecture. It has been identified as an independent fracture risk factor and may prove useful in further stratifying fracture risk among those with a bone mineral density (BMD) in the osteopenic range (-1.0 to -2.4 standard deviations), in those with low-energy fractures but normal or only mildly low BMD, or in those with conditions known to impair bone microarchitecture.

➤

Fracture risk assessment tools, including the Fracture Risk Assessment Tool (FRAX), Garvan fracture risk calculator, and QFracture, evaluate the impact of multiple clinical factors on fracture risk, even in the absence of BMD data. Each produces an absolute fracture risk output over a defined interval of time. When used appropriately, these enhance our ability to identify high-risk patients and allow us to differentiate fracture risk among patients who present with similar BMDs.

➤

For challenging clinical cases, a combined approach is likely to improve accuracy in the identification of high-risk patients who would benefit from the available osteoporosis therapies.

Rates of Osteoporosis Management and Secondary Preventative Treatment After Primary Fragility Fractures

Fragility fractures are often sentinel events in documenting new cases of osteoporosis. Numerous analyses have demonstrated low rates of adequate osteoporosis evaluation and treatment following primary fragility fractures. The purpose of this study was to quantify the incidence of primary fragility fractures in America and the rates of osteoporosis screening and management before and after fracture.
