Osteoporosis among older Saudis: risk of fractures and unmet needs

The management of osteoporosis in hospitalized patients with fragility hip fractures in western Saudi Arabia: a real-world tertiary center experience

Osteoporotic fractures, especially fragility hip fractures, are major causes of mortality and morbidity in the elderly. There is a significant gap in the diagnosis and treatment of osteoporosis in patients with fragility fractures. Vitamin D use increased by 18.2% post-admission, while calcium use rose by 21.1%. Additionally, the prescription of bisphosphonates, an osteoclast inhibitor, increased by 1.2% post-admission. The study highlights the urgent need for improved management practices and more proactive care strategies to address osteoporosis and its complications.

INTRODUCTION

Osteoporotic fractures are a major cause of fragility hip fractures, and in Saudi Arabia, the high prevalence of osteoporosis and high costs highlight the need for comprehensive care. This study aimed to evaluate the management of osteoporosis in hospitalized patients with fragility hip fractures in western Saudi Arabia.

METHODS

This retrospective cohort study examined medical records from individuals with fragility hip fractures at King Abdulaziz Medical City in Saudi Arabia, Jeddah, from 2004 to 2024. Data was collected from electronic health records, including demographics, clinical features, comorbidities, fall history, osteoporosis diagnosis, and medication usage.

RESULTS

The study included 314 patients, with a mean age of 73 years and 31.2% being between 71 and 80 years old. The majority were females, with a mean BMI of 26.6 kg/m2. The most common comorbidity was renal failure. The prevalence of pre-admission diagnosis of osteoporosis was 14%. Post-admission DEXA-BMD use was reported by 16.6%. Vitamin D (41.1%) and calcium (42.4%) were higher in post-admission management compared to pre-admission management.

CONCLUSION

The study found that most hospitalized patients with fragility hip fractures were female, overweight, had a history of falls, and suffered from renal failure. This study opens new areas for future research that could increase our understanding of osteoporosis management.

Diagnosis and management of osteoporosis in postmenopausal women in Gulf Cooperation Council (GCC) countries: consensus statement of the GCC countries' osteoporosis societies under the auspices of the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO)

A consensus platform is provided by the experts of the Gulf Cooperation Council (GCC) countries' respective osteoporosis societies, on which specific guidelines can be developed further for regional use on the assessment and treatment of postmenopausal women at risk from fractures due to osteoporosis.

INTRODUCTION

Guidance is provided in a Gulf Cooperation Council (GCC) country setting on the assessment and treatment of postmenopausal women at risk from fractures due to osteoporosis, which is an adaptation of the European guidance by Kanis et al., jointly published by the International Osteoporosis Foundation and the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO). The respective osteoporosis societies of the Gulf Cooperation Council (GCC) countries assembled for a unifying consensus on the diagnosis and management of osteoporosis in postmenopausal women for the region.

METHODS

The Chair for Biomarkers of Chronic Diseases (CBCD) in King Saud University (KSU), Riyadh, Kingdom of Saudi Arabia (KSA), in cooperation with the Saudi Osteoporosis Society (SOS), hosted regional experts and respective leaders from different GCC osteoporosis societies, together with an adviser from the ESCEO. An assembly of experts representing the different osteoporosis societies from Saudi Arabia, the UAE, Bahrain, Oman, and Kuwait gathered on February 15-16, 2019 in Riyadh, KSA for the formulation of a general osteoporosis consensus for the region.

RESULTS

The following areas were covered: diagnosis of osteoporosis and assessment of fracture risk; general and pharmacological management of osteoporosis; and hip fractures, vitamin D, recommendation on which FRAX tool to follow, and the importance of country-specific FRAX® and fracture liaison services for secondary fracture prevention.

CONCLUSIONS

A platform is provided on which specific guidelines can be developed for regional use in GCC.

Screening to prevent fragility fractures among adults 40 years and older in primary care: protocol for a systematic review

PURPOSE

To inform recommendations by the Canadian Task Force on Preventive Health Care by systematically reviewing direct evidence on the effectiveness and acceptability of screening adults 40 years and older in primary care to reduce fragility fractures and related mortality and morbidity, and indirect evidence on the accuracy of fracture risk prediction tools. Evidence on the benefits and harms of pharmacological treatment will be reviewed, if needed to meaningfully influence the Task Force's decision-making.

METHODS

A modified update of an existing systematic review will evaluate screening effectiveness, the accuracy of screening tools, and treatment benefits. For treatment harms, we will integrate studies from existing systematic reviews. A de novo review on acceptability will be conducted. Peer-reviewed searches (Medline, Embase, Cochrane Library, PsycINFO [acceptability only]), grey literature, and hand searches of reviews and included studies will update the literature. Based on pre-specified criteria, we will screen studies for inclusion following a liberal-accelerated approach. Final inclusion will be based on consensus. Data extraction for study results will be performed independently by two reviewers while other data will be verified by a second reviewer; there may be some reliance on extracted data from the existing reviews. The risk of bias assessments reported in the existing reviews will be verified and for new studies will be performed independently. When appropriate, results will be pooled using either pairwise random effects meta-analysis (screening and treatment) or restricted maximum likelihood estimation with Hartun-Knapp-Sidnick-Jonkman correction (risk prediction model calibration). Subgroups of interest to explain heterogeneity are age, sex, and menopausal status. Two independent reviewers will rate the certainty of evidence using the GRADE approach, with consensus reached for each outcome rated as critical or important by the Task Force.

DISCUSSION

Since the publication of other guidance in Canada, new trials have been published that are likely to improve understanding of screening in primary care settings to prevent fragility fractures. A systematic review is required to inform updated recommendations that align with the current evidence base.

A systematic review of intervention thresholds based on FRAX : A report prepared for the National Osteoporosis Guideline Group and the International Osteoporosis Foundation

This systematic review identified assessment guidelines for osteoporosis that incorporate FRAX. The rationale for intervention thresholds is given in a minority of papers. Intervention thresholds (fixed or age-dependent) need to be country-specific.

INTRODUCTION

In most assessment guidelines, treatment for osteoporosis is recommended in individuals with prior fragility fractures, especially fractures at spine and hip. However, for those without prior fractures, the intervention thresholds can be derived using different methods. The aim of this report was to undertake a systematic review of the available information on the use of FRAX® in assessment guidelines, in particular the setting of thresholds and their validation.

METHODS

We identified 120 guidelines or academic papers that incorporated FRAX of which 38 provided no clear statement on how the fracture probabilities derived are to be used in decision-making in clinical practice. The remainder recommended a fixed intervention threshold (n = 58), most commonly as a component of more complex guidance (e.g. bone mineral density (BMD) thresholds) or an age-dependent threshold (n = 22). Two guidelines have adopted both age-dependent and fixed thresholds.

RESULTS

Fixed probability thresholds have ranged from 4 to 20 % for a major fracture and 1.3-5 % for hip fracture. More than one half (39) of the 58 publications identified utilised a threshold probability of 20 % for a major osteoporotic fracture, many of which also mention a hip fracture probability of 3 % as an alternative intervention threshold. In nearly all instances, no rationale is provided other than that this was the threshold used by the National Osteoporosis Foundation of the USA. Where undertaken, fixed probability thresholds have been determined from tests of discrimination (Hong Kong), health economic assessment (USA, Switzerland), to match the prevalence of osteoporosis (China) or to align with pre-existing guidelines or reimbursement criteria (Japan, Poland). Age-dependent intervention thresholds, first developed by the National Osteoporosis Guideline Group (NOGG), are based on the rationale that if a woman with a prior fragility fracture is eligible for treatment, then, at any given age, a man or woman with the same fracture probability but in the absence of a previous fracture (i.e. at the 'fracture threshold') should also be eligible. Under current NOGG guidelines, based on age-dependent probability thresholds, inequalities in access to therapy arise especially at older ages (≥70 years) depending on the presence or absence of a prior fracture. An alternative threshold using a hybrid model reduces this disparity.

CONCLUSION

The use of FRAX (fixed or age-dependent thresholds) as the gateway to assessment identifies individuals at high risk more effectively than the use of BMD. However, the setting of intervention thresholds needs to be country-specific.
