Secondary prevention of fragility fractures in Asia Pacific: an educational initiative

The Asia -Pacific Bone Academy (APBA) Fracture Liaison Service (FLS) Focus Group educational initiative has stimulated activity across the Asia -Pacific region with the intention of supporting widespread implementation of new FLS. In 2017, the APBA FLS Focus Group developed a suite of tools to support implementation of FLS across the Asia-Pacific region as a component of a multi-faceted educational initiative. This article puts this initiative into context with a narrative review describing the burden of fragility fractures in the region, the current secondary fracture prevention care gap and a summary of emerging best practice. The results of a survey to evaluate the impact of the APBA educational initiative is presented, in addition to commentary on recent activities intended to improve the care of individuals who sustain fragility fractures across the Asia -Pacific. A FLS Toolbox for Asia-Pacific was developed which included the following sections:1. The burden of fragility fractures in the Asia-Pacific region.2. A summary of evidence for FLS in the Asia-Pacific.3. A generic, fully referenced FLS business plan template.4. Potential cost savings accrued by each country, based on a country-specific FLS Benefits Calculator.5. How to start and expand FLS programmes in the Asia-Pacific context.6. A step-by-step guide to setting up FLS in countries in the Asia-Pacific region.7. Other practical tools to support FLS establishment.8. FLS online resources and publications.The FLS Toolbox was provided as a resource to support FLS workshops immediately following the 5th Scientific Meeting of the Asian Federation of Osteoporosis Societies (AFOS) held in Kuala Lumpur in October 2017. The FLS workshops addressed three key themes:• The FLS business case.• Planning the FLS patient pathway.• The role of the FLS coordinator in fragility fracture care management.A follow-up survey of 142 FLS workshop participants was conducted in August-September 2018. The survey included questions regarding how FLS were developed, funded, the scope of service provision and the support provided by the educational initiative. Almost one-third (30.3%) of FLS workshop participants completed the survey. Survey responses were reported for those who had established a FLS at the time the survey was conducted and, separately, for those who had not established a FLS. Findings for those who had established a FLS included:• 78.3% of respondents established a multidisciplinary team to develop the business case for their FLS.• 87.0% of respondents stated that a multidisciplinary team was established to design the patient pathway for their FLS.• 26.1% of respondents stated that their FLS has sustainable funding.• The primary source of funding for FLS was from public hospitals (83.3%) as compared with private hospitals (16.7%).Most hospitals that had not established a FLS at the time the survey was conducted were either in the process of setting-up a FLS (47%) or had plans in place to establish a FLS for which approval is being sought (29%). The primary barrier to establishing a new FLS was lack of sustainable funding. The APBA FLS Focus Group educational initiative has stimulated activity across the Asia-Pacific region with the intention of supporting widespread implementation of new FLS. A second edition of the FLS Toolbox is in development which is intended to complement ongoing efforts throughout the region to expedite widespread implementation of FLS.

Thai Osteoporosis Foundation (TOPF) position statements on management of osteoporosis

The adjusted incidence rate of hip fracture in Thailand has increased more than 31% from 1997 to 2006. Mortality and morbidity after hip fracture are also high. One year mortality after a hip fracture has increased from 18% in 1999 to 21% in 2007. The Thai Osteoporosis Foundation (TOPF) developed the first Clinical Practice Guideline (CPG) in 2002 and keeps updating the CPG since then. This latest version of the CPG is our attempt to provide comprehensive positional statement on the diagnosis, prevention and treatment of osteoporosis in Thailand. The study group who revised this position statement contains experts from the TOPF, Four Royal Colleges of Thailand, includes the Orthopaedic Surgeons, Gynecologists and Obstetricians, Physiatrists, Radiologists and 2 Associations of Endocrinologists and Rheumatologists which have involved in the management of patients with osteoporosis.

A nomogram for predicting osteoporosis risk based on age, weight and quantitative ultrasound measurement

INTRODUCTION

Quantitative ultrasound measurement (QUS) or clinical risk index alone are not reliable tools for the identification of women with osteoporosis. This study examined the prognostic value of combined QUS and clinical risk index for predicting osteoporosis risk in Thai women.

METHODS

The study was designed as a cross-sectional investigation with 300 women of Thai background, aged between 38 and 85 years (mean age: 58). Femoral neck bone mineral density (BMD) was measured by DXA (Hologic QDR-4500; Bedford, MA, USA). A femoral neck BMD T-scores <or= -2.5 was defined as "osteoporosis"; otherwise, "non-osteoporosis". QUS was measured by Achilles+ (GE Lunar, Madison, WI, USA) and converted to T-score. Three models for predicting osteoporosis were considered: model I included age, weight and QUS, model II included age and weight, and model III included only QUS. The prognostic performance among the models was assessed by the area under the receiver operating characteristic curve (AUC).

RESULTS

The prevalence of osteoporosis was 12.7% (n=38/300) by femoral neck BMD. Age, weight and QUS were each significantly associated with osteoporosis risk. The AUC+/-SE value for model I was 0.86 +/- 0.03, which was significantly higher (p=0.02) than that for model II (AUC = 0.80 +/- 0.04) or model III (AUC = 0.79 +/- 0.04). Based on the estimated parameters of model I, a nomogram was constructed for predicting osteoporosis.

CONCLUSION

These data suggest that the combination of QUS and age and weight could significantly improve the prognosis of osteoporosis in Asian women, and that the nomogram can assist primary care physicians in the identification of high-risk women.

Fracture threshold in the Thai elderly and bone mineral density evaluation

Fractures in the elderly as the result of minor trauma or normal physiological stress in daily activities usually occur in load-bearing body areas such as the lumbar spine and the neck or trochanter of the femur, causing high morbidity and mortality. Surveillance of high-risk Thai elderly with low bone mineral density by determining the cutoff point as the fracture threshold may guide us in the proper management for preventing these unpleasant events. Of 329 elderly with age range of 50-110 years, 63 with lumbar spine fracture and 55 with hip fracture were descriptively and studied prospectively during May 1997 to December 1998 at Pramongkutklao Hospital. Bone mineral density (BMD) was analyzed to determine the fracture threshold using a receiver-operating characteristic (ROC) curve and compared with the total BMD at the lumbar spine and proximal femur. The cutoff point of the lumbar BMD at 0.799 g/cm2 (78.30% sensitivity, 73.60% specificity, and 74.5% accuracy) yields the likelihood of lumbar spine or hip fracture. For the femoral BMD, the cutoff point at 0.649 g/cm2 (92.5% sensitivity, 73.2% specificity, and 73.05% accuracy) is also used to predict the likelihood of lumbar spine or hip fracture. Of the nonfracture group, 27.33% had a total BMD value below the fracture threshold. In conclusion, early prevention among the elderly to decrease the risks of fracture is very important. Also, the detection and fracture prevention for normal population who had BMD below the fracture threshold are interesting. The BMD measurements and the loss of bone mass in Thai elderly people and the other risks of fracture need further studies.
